A

Hi good evening, people from Brazil Good morning or good afternoon for those who are watching us from other parts of the world welcome and welcome to the second edition of that gift card gift. My name is Priscila and I you, the host of this event, today I'm going to start here share on my screen with you. We start the conversation.

A

A good show guys this second edition of our event that started for the first time in august of this year. Little technical problems guys technology anyway, but anyway I will introduce myself to you that still didn't participate in the event.

A

For you who still don't know us, her name is Priscila, reread I'm brazilian from Minas Gerais and currently I live in near the city of Chicago and I'm part of hip-hop in the support team and release William, so I help our team to give the best technical support to companies, and it should be the best way possible and I live here with my Black Duty dogs as well as you can see, him walk, I'm here and I'm, also part of orthogas, which is an affinity group for people of Latin descent, and the author explains to the group that has been helping us, create and organize these events, and he brings the cultures about to be delivered Shelby helping.

A

We even have a support group and friends before work, as I mentioned to you. This is the second event, and it is part of the commitment that, via terrazzo has with Latin America is one of the points that we always want to emphasize is that the gift Hobby within Latin America from Brazil, Mexico and other countries? Sorry we're listening to a feedback.

A

So listening to me talk and sent an appointment following hobby is for us to maintain a collaborative relationship and that's why we are organizing these events, in addition to maintaining documentation in Portuguese and Spanish,, which is very important,. The novelty has already started this year.

A

tro of Latin America in general. Is we also have a super interactive and new group within it, Charm Actually, two and short Stories, and the key Campos is that I'm going to talk a little more about them? Today we have the forum for our must-have community that now there is also the possibility that you can write in Portuguese or in other languages, and we also have the Big C op mobile application that is compatible with Andro d and Apple and t.

A

Day, I wanted to point out that and gives a very pecial highlight to two two inter al groups. Here it rains on the truth they are. Representatives of the Communities must here Shelby is that they are the hip hop Stars. Today we have three steps that is Júlio, Arruda, Mário, Souto and William. Justin is what you should be. Is a recommendation or reference program for people from the Brazilian community can indicate who they think or who owe them?

A

Brazilian people think that they are good leaders in the community and that they bring value to communities living in the Brazil So. If you know someone who has all the characteristics, indicate this person to participate in Tiago estar's program and to indicate this one visit, stories.de, xat.com Hi and the second group that I wanted to highlight today that it is very important- has a place special in our hearts. Only hip hop Campos EcoSport. Today we have four Campos at forces that are Otávio, Germano,, Otacílio and Gui is to know more about this program.

A

You can visit this page with like on your screen and on the same from the rapid oberfest,, which is this special month of october,. They have created content and tutorials workshops that help new and experienced must participate in the rapid oberfest to contribute code to others. Only if and they also create content to help. You learn more about programming in general and Ricardo in general is also not worth checking the program, and if you don't have these people in your social network already add them there. On Linkedi n on Twitter.

A

Is a message a little bit about fast berfest? How could I do this event today and not mention to you at the Raptor berfest table? What you know is also actively participating in case you haven't participated yet there's still time for the party also happens on the day, October 1st, until the Thirty-first of October It's. Up to today, we have more than 500 thousand pieces that have already been created and in almost 700 events, organizers within the community were also created.

A

One of their events that I had the honor to participate in was organized by the EcoSport Otacílio Maia campus. That, for this event, is like a workshop and lectures is for the team of the community must in Recife, so don't stop participating.

A

And now, especially I want to show you our schedule for the day, and it will have two videos Robert bringing information about mpm and security in open-source software later we will have Taiana and will talk about democratization of r Augmented reality on the web. We also have Hernandes talking about legacy projects and finally, Lucas who will talk about weed language, which is a language completely in Portuguese created by Brazilians.

A

Here, as you can see, there are Brazilians should go out in difference every day, our community and, at the end of the event, invites you to wait. A little bit.

A

André Eleutério talking about sharing security in Open Source software What's up And.

B

What about the fish and Priscila you just have to confirm for me if you can see my screen, everything is ok before starting here.

B

And I just shared.

B

It 8 years ago my name is Andréa seriously: I'm a Nubian security researcher and I'm going to talk a little about sharing security in an open s, software ource And. How can Beach rugby help in this process start ensuring that all software has a vulnerability, and that is inevitable because it suffers ages. Software is not something static, it will stay like this forever. After all, the paintball of your software is no longer supported. It already has four new versions: a critical dependency was the people was abandoned, or else you have another dependency Here.

B

You have a community that directly affects you at other levels in the deposit, application can be vulnerabilities, and this is very inevitable. It is much more a matter of time until you find one profitability or how much will be invested to find a priority in this project, right,. The focus ends up being and ensures that people can update these software or at least make their own decision on whether or not to update these safe actions.

B

vulnerability in open source software and one that keeps this and suffer hasn't corrected it. Another way, skill is just a blog, and the consequences of this rubbish is true that make a situation more complicated right. Then it will run away in the same way as a bath. I, don't know it was a dependency of yours and the function expected three Paraná na new version. I was just waiting for one more and you updated the package but authorized the code suddenly it broke. This is a bug right. This can be a shade.

B

It just depends on what will happen after that, for example, a book I tried to log in with my credentials correct, and there was an error. This is a boy now I tried to log in with my credentials and ra and hence the much more dangerous consequence right. You have a vulnerability. My session expires every 20 seconds and they are bug. It's just annoying because he's trying to use and probably goes, the other thing but I, don't even session- expires every 20 years. That's.

B

Of course a skill spoon speaks when you need a reasonable time there to wait sessions, it's unusual characters and they tend to be wrong on the screen. André Carvalho's acute accent appears that little square of the old flashlight is boring, is ugly, but a blog now features uncommon generates an exception when crashing down the whole system. So it's a problem right I, like André André, goes knocking down the center everyone a much more dangerous consequence and with the consequences are so much more plastic.

B

It is important to think about the process of correcting this vulnerability in English. It is called a bear possible to discuss just to be well chip, but it is important that this is done in a way responsible, right, then, in terms of the process, Today I'm So,.

B

First, you have to know the report sent to know this seriousness in some way,, especially in a private way,, for us to be able to enter into a pact because he has to do what he has to use just to then after I maintain software, I have to fix a problem in some way, right and preferably in coo operation with those who found the vulnerability, luckily to test together to ensure that the worst eaten is and, lastly, warning the community right Mainly, it is getting from the consortium so that they always publish some kind of statement, warning the eyes of the Risk and that whatever you don't take, are insecure and how to protect yourself, then for proprietary software, and this ends up being easy.

B

After all, the company will have a team to receive the reports to correct the problems that will have security to test these corrections and then a whole infrastructure to disclose and ensure that the eyes are not aware and go to being able to update. Now when it comes to cancer, if I don't understand these same facilities can How. Many is the same person doing the three steps there at the weekend with time. So that's what they have ways to help.

B

Whoever maintains software on each woman quote and that's what I'm going to talk a little about the next few minutes there, so the first r part of getting the ones she can security from the most critical here is that this has to be done in a private way.

B

To avoid the says, zero day, smoking skill, which is one of the worst situations that can safely happen, which is this is when a woman skill is publicized, becomes known to the public before anyone who writes software, that has the skill fix this severity because then, suddenly it's on twitter. Everyone knows everyone can be hacked. Mainly. This involves is some proof of concept and a test a demo and how to test.

B

If gravity and beauty Porto is the photo that everyone will start the day the fastest right, then it's very important that it be done in a private way, so that the developer, who maintains this only has time to correct the anfalpet and then disclose it, but when it waits for public, there is already an easy way for users of this suffer to update themselves. And stay safe together is, and what ended up happening many times that a ends up being done in a public garbage in which I can be free of rap.

B

Someone opens a school community here. Does it like this? This can be very complicated even more than just for the staff. If you may not have time to correct that immediately, it was not prioritized.

B

You can omit this because it ends up helping a lot and, if I'm, because it was chic to think that he has a lot of chic project watching this event here today and if you have your own domain,, make a mile to email to redirect the email Security@tem a domain.com, because it is very common for researchers to try it on yourself and before asking for the room, are ways: ok with that, always looking at the time.

B

In addition to getting very fancy, it will be very useful for researchers who tried to contact your project and to do this irresponsibly. But the main thing is what you like here: MG is what I'm going to now follow that it's a communism file,, it's just that it's a security policy. It's your project's security policy, and that means you enter there in the Security Security policies tab.

B

It will be a document who has this document is preferably in the ideally, there will be some information there, so buy cut, eat skills here on the right side, I put the police watch, this security policy in a very big night project called Alex, Tom and Tele. In it to report a problem to e-mail mom to such Ah yeah So, this is very important. The first thing a searcher of the wanted.

B

You can yes, but also there are other project security things that may be important to put, for example, general considerations about the security of the project. Is, for example, you make software that was actually only to be used within a secure and controlled network was not made to be exposed on. The internet is very important. All eyes are in the know, and this security policy is a great place to put this information.

B

Another thing is that many times the code will have security barriers just to protect users, but that sometimes limit the flexibility of how you can use this soca, and it is possible to disable certain settings that give us security and take away. Flexibility can only be a shot in the arm, developer, foot right and it's very important that these issues are well described. An inherent example. Aunt Nelma is for those who deal with web development Beauty. You can use this function to avoid SKY and they don't get to understand it a little better.

B

It's very dangerous of you to use if arbitrary inculcates there, so it ends up being very important. It leaves Clear. The function part is dangerous cause. It goes this way. It helps a lot of developer. Who is consuming this information, this file that followed that it is the reason why Mark gives a just like the regime believe rendered there on the homepage and he gets this safety. Water Just put a reason it's on Mars, from where you took the one that contains Dino Rush from your project.

B

What sort of thing You already take care of presenting it in the right place, just correcting For when she screams, like I, mentioned it before it's the first text, that's it with whoever reported eating skill after all after all,. Sometimes a test was passed in this Field Put this wicked and give this problem Beauty. You corrected it and simple, but there are others. In fact. Sometimes the correction with very specific was not generalized enough and that's what you should be able to identify at least is one courtesy na cutout eating here.

B

Only this from teste bola is, and the Ruby kit manages to facilitate this communication. Excess here. I do n't tell you when you start the process of disclosing a vulnerability. You don't have the code. It is possible to open a private, temporary, strong that allows the developer and to anyone wishing to be added to this temporary stronghold or to share information, right,. Do the back and forth.

B

While it was right here., the city is alert, but there are other things that are important that help a lot Whoever is trying to do its location first is to correct it in other versions, not only in the latest Brent and right in the newest one, but to make a package for another helps many people who can having difficulty updating the latest version depending on infrastructure issues. There are n reasons why updating a suffer can be difficult.

B

Another point to identify the committee with the correction if it happens, send the comment correct the truth, put a message that makes it clear: that's what it's happening there, because whoever goes to give him what he suffers has to later understand the vulnerability more in depth. Will probably go into the history and how they try to find where it was fixed, helps a lot already have that clear and finally, what to see, if it more difficult that include testing even to eat skill in the code.

B

That is, of course, has all the questions as to why it doesn't want to be imposed: It's important for development,, but as a whole to fix bugs, right then,. Just like any bug,, you do a test, so you do n't have a regression that the boy exists again,, but when it comes to a skill,, it also matters who's pressing consume. This you can see the test can try to reproduce right to see if it is affected, if it is not, any extension of the problem test are important.

B

Is another beautiful way to be very thorough about this and now here the last part that ends up being to disclose this vulnerability users right and it is the part that is lacking and often there is no way to do it properly. So the Ruby kit provides an entire infrastructure for security communication. They are formed of what will be able to have peace. They are used a lot and it is the the way that what opens you allows admins to do this, and hence also a matter of beauty once I created this.

B

This announcement is in the repository co so that everyone knows right,, it's certainly a question to start at the beginning. So what is this security announcement in the tyrant is what I have right here on the screen. This is an example of a communiqué that I gave you last week in a package. Then the scripts, only those from me from the repository can create how many and it will not have Fields there. You can see the risk in this high house.

B

The name of the package does are the numbered questions which are safe and mainly the details are what that governance is actually written there, and what 's really cool is that once you publish this safety bulletin, it is automatically transmitted through dependabot and ntm Oil of making sense So, whoever keeps it just for what they love must have already received it. Several Terres do depend on the court to update the dependencies and such- and this is one of the sources of this information or certainty.

B

When this is published, and my uncle we see right What is food, the skill and does this transmission, both behind that Box, when it has oil who works with JavaScript, has already done. It has a sun and appears there. It is because the question skills this is also one of the origins of this information by these security announcements and it is in a state, does not have a repository light enter nothing Follow, Follow, current jobs of all that were created for that specific repository, and this from here.

B

As you create this announcement for your own repository, you go there Security, Security advisors, and if you are from me, it was an option. New draft Survival can I make a draft of a new one, and here are the fields of the form it has to be filled in the title. What are the versions it Gives me the time, mainly the larger field. That is, with the description of the eating skill. The details so is.

B

Maybe it is not this one inform sometimes he is just very clear on what he expects from whoever is disclosing In fact. It is being done, and there will be this one for him in the future uro next, yes, you who are watching have some kind of feedback about this.

B

Please contact me directly and bring it could be better what helped I'm not and discussing internally, because the idea is just to help the community right and ensure that these announcements are as clear as possible and that really help those who are building, but that make life easier for those who are publishing, keep keeping this one was only achieved with responsibility and now I'm going to write in this statement. I like Dina and since there's nothing about this code, that I write there to make it clear here. It's building and there's a problem.

B

It's first that you don't want to eat skill right like there in that. As you said, the father is missing: pollo-chan buá buá buá injection cycle in the application. This is certainly where it starts, but where it gets harder is when always writing. What is the impact on users that has very strong where it is not necessary. I declare How, the user will use only still the most was a package, or sometimes there are questions from the deponent, an application in an infrastructure that is different from that one,.

B

It's difficult for you to say what the impact will be on everyone and to help people make their own judgment on their own,. There are some items that are certainly important, for example, say what the vulnerable function is. If that makes sense, because if it's a package that depends on the funeral function and I don't use this function, so I can leave this note for later, or else I can focus in something else. I can prioritize your reality.

B

Differently is once again the invitation that correct the ponderability before I said to put a message on the invitation when you do right, Your current there in charge more here when you write this communiqué, clean glass, Comment, the Job's path was in comic-x has been fixed, is very interesting. When possible also put an attack scenario: That is, I write to you with But. This can cause a problem from the hacker who accesses the application of the problem, for example,, a malicious person, an access to the input field, dick in a privileged network position.

B

I, don't know why a tom who can do that that helps a lot who is watching to to be able to understand if certain parts of this scenario are applicable or and how many security barriers often have several barriers, and it may be that more and one of them there with this problem Hello, how do I get the original report of the vulnerability? Also, this document, this communication is the one of accounts even for the transparency and how this arrived can help.

B

A lot is other things that can help the person to make an appropriate decision. First is the conditions that increase or decrease the risk. For example, if you use this this package with a stick option, you have no problem. Ok now, if you use it with another configuration, then you have a greater risk. It is very important that you leave it well described how what these are. People can mitigate the risk by hand and it's Make it clear. What are the safe solutions.

B

After all, for a lot of people, what this safety announcement will serve is to see. There's a Bonner skill is correcting here, Disney, the milk, so making this clear already helps him a lot. There are specific fields for that,. It's not, and an important part is if there is any way to protect yourself without doing an update after all,. Sometimes you can't update that one. The product team said you can't can't do that.

B

Now, it's going to have to stay for 3 sprints from now and we'll do it,, so sometimes there's a time, give you, for example,. If it's a configuration that is safe. If you find it without this configuration.

B

All the difference for those who consume good, but and to spread the news here for the whole world to know there that we use these identifiers called you see like a come on Lilo Listen next post right, then it is a global identifier that serves to officially identify a vulnerability and ensure that it is not duplicated after all, imagine there is only one vulnerability in the repository and such and then suddenly there is a way that you differentials can generate a lot of confusion in the double work with a lot of people,.

B

So this is an idea,. The identifier in this format, CV dash the year dash five digits and everyone has a global structure of who can assign these services. Are the operations have their scope, right and each one can assign these to projects that makes sense to you within these body, and the This identifier will always be painted a reference to a security release.

B

Where this was is really to disclose so general, for example, you can big here at the end there there is a link to get it goes to the original, and it is by example, Red Hot Toys, its own services glasses. Now pro that runs on the Ruby kit right for the subte repository Rubi kit itself can give these CV identifiers, and when you publish a security announcement,, there is an option: Wiki quests IV.

B

What my team will get and we will evaluate whether or not it makes sense to deliver an identifier like that that is already known globally, and what is the importance of what this is,? You can see there if you give it being official and being unique, it is the only source of information for many tools and databases around the world. For example, there are several tools that companies use where you already, you know all the glasses you have and from that you know that you are vulnerable, right,.

B

If you stay alone on the coast,, the scanner is contained here to get the and database like NBB,, which is from the American government and which is very respected and categories to everyone on CBS and it's more difficult to ask for it in a CV is a way that I've already seen in the communiqué to warn the whole world and then start this whole process of updates, right and your users can be get insurance as quickly as possible and hope it doesn't have any issues until then And.

B

That's what I had to talk about today about sharing security and others Force about how you got it can help in this process, I'm available, anytime, Twitter link or at any platform to talk a little more about it. Thank you very much for your time. I'm going to spend around the pool.

A

I'm back guys when it goes wrong, we'll come back later, we'll try again I went we'll go then it's pass to the next person who will be our speaker is father Ana and then in the middle of the way you go. We try to make a right single support here and we stay on the street. Back can be.

C

A

C

A

In the middle of the way, let's change here quickly for questions techniques, But the bad will come back like this information about npm set and then I would really like to invite the next person who will speak at today's event that Taia it's not that it's part of an open-source project related to augmented reality, and he and she have a bachelor's degree in computer engineering from Estácio, E, S, A, M I, know your University, but then you're doing it there and I'm very pleased to invit Taiana to meet her personally for a short time and the work she is doing both in terms of representing Brazil in the project is international caught.

A

My attention and I believe that what she has to share with you today will open many eyes and we create opportunities so without further ado, Daiana,. Please go talk to us. A little., Hello everyone,.

D

All the best Good night, I want to thank you for the invitation to be here.

D

D

A couple of years ago- and it was thanks to the existence of this library- it initially started with a library that I entered the world, right. Let me share here my screen, well here it is, here is rjs studio, right, democratizing, augmented reality on the web. I bring this title right, because maybe someone has already heard about rjs right I'm, going to talk a little bit about it. First of all, I'm going to talk a little about it me right, but you didn't call me Taiane.

D

The Mamoré belt I'm from Belém do Pará and I'm in love with a people right, I'm, enthusiasm for web technology in the simple calls the fxr and it's nothing more than virtual reality. Augmented reality on the web. Currently community organizer saw gesnort,, which is a local community here in Belém, do Pará and is part of the a rjs organization, development, team.

D

About reversible technologies right because I used this term, because the web doesn't talk about the rjs library, right,, the types of augmented reality that they have and talk about the platform in the studio right and doing a little practice. If you give time and here about reality, when we talk about technologies and miscibles right, we are talking about virtual reality, mixed and extended, augmented reality and in English it is It, is known by these as VR a rmr XL isn't virtual reality. Isn't it what's growing there every moment it's when I?

D

Have it I completely lose the notion of the real world and its immersed in the virtual world isn't augmented reality. Now I bring the digital world to my real world right, so through devices, in this case, mobile devices are being used. A lot, like the Smartphone and tablet, I can be there through it, right? There is an intermediary to be able to be viewing. My digital content in the real world and mixed reality is when I make a junction of the two, right there, in the example,.

D

In this example that I brought the girl, she's using the rolence Right,, it's a mixed reality, glasses, right then I can I can be viewing the digital content and, at the same time, interacting with my own hands. When I talk about the three, right That's, when I bring the XR, right, that the extended reality Today,, it does n't end up ah ah,. It ends up walking, along, right? the two end up walking together both augmented reality and virtual reality.

D

So it ended up being the most used now the XR, right,, which is the extended reality And then I, come here, I bring you to go, right because I talked about augmented reality on the web, And, then I come and I. Ask because the web I'm going to tell a little story, right. Let's say we have us in an image gallery right And, then something very common that I don't know if it's happened to you, but it's something that will end up being common, but increasingly common is to see information like this,, right Then.

D

When we look at it, we already know that it is a mobile application that we will need to download So. We will have to have it on our smartphone one right access the Access, the app the app. How are the apps in the Store and to be able to download to be able to download right? The app will be able to see some experience more right, Hi and then I come to bring you the dark side of mobile apps I'm, not here saying that the mobile application is not good,.

D

Ok, people, I have a lot of people who stay Wow, but do I have to give up the application. Again,. That's not it,, that's what it's all about in each case,. It's in the case for developers. The high cost for development, construction and launch of the application, for in the case of the BIOS, I need to have a Macbook to be able to develop the application and it must have a developer license for Android and IOS for the user, right?

D

There is the issue of finding the application in the Play Store stores, like the Apple Store in the image I showed there was the QR Code, right,, but it's that thing,, the smartphone, it already comes with the integrated QR Code reader,. Then it will be more It's, an application that the user will need to download And.

D

Then I'll have to install this application, And that if there 's space available, right How many times, we don't have several applications and then, when we want to install a new one, we don't have a no there's more space available,. So there we go, the old saga, right, of trying to keep it up to date, right?.

D

Then, when I can't,, it's updating, because there's no space to remember its existence, right in this case, and then remember to delete that precisely it falls into that situation. That I'll only remember that I have the application. When I'm going to need to install another one,, then I I'm, going to wash it, I go looking And then I see an application that I've never installed it again,, just once, I used it only once,. So here I bring some technology solutions,.

D

It's augmented reality reality of virtual on the web. In the case of this year, 2020 for solutions or prices right I bring these lists there. The ai j.so fxr of will know I j, sart20, 5 and so on. Right for paid solutions we have the etiol. One is pretty cool, only that it has a limitation of use and then for opensource virtual reality solutions.

D

We have the iframe YouTube and if I highlight here the JS, the fm, because it brings up a lot this issue of democratizing right in a little while I'll tell you you, because, because I used that word, that's right,, rjs, I, don't know. If many people know it, it's a library, right java script,, it's the dressing, right, It's cross-browser, which means that it supports multiple internet browsers and since the beginning it started as a marker- based version 2 that was released in october last year.

D

It was a location-based one and the beginning of this year it launched version three with image tracking come back talking a little bit about And. Then here I'll talk briefly about how this is possible with a virtual reality. Augmented reality is possible in the browser. Thanks to these three apis right webrtc, the LG l, o l x, RBR pc-app responsible for making the web browser communicate with the device features both mobile and device, as well as the PC is webgl guys. He is the p I responsible for rendering graphics in the browser itself.

D

Right and fxr is what makes reality virtual reality. Augmented reality happen on Android. Basically, all browsers will good, ok, good, it's giving a nice experience, I use rjs, then I leave a little a little cold note, because it will only work from version 11 right. It will have a better experience and it has to be in the Safari browser.

D

Ok, UFRJ is, if it is the library it was augmented reality. It is possible, thanks to these three, it was killed right. Waifray What did I mention right that it is a JavaSc tremor, ript, augmented reality by the way, sorry virtual reality created initially by Mozilla foundation. The sad thing is that the sick person turns out to be a distrijazz refrigerator right. He's a library I've seen a writer responsible for rendering graphics right and the j r, a r of the kit, which is what what is a library, makes you.

D

The marker based is possible, and here I will talk about the people behind this of projects right money me étienne. He is, he was the person who started the rjs library, so there in 2018 2017/2018. He started right and started with the marker based and Ione put Pig. Look. He is currently is ok. How did the organization create rjs right in Itaú today as the leader right of the team team talking a little here about the types right, the one based on the bookmark, the content it is displayed over the bookmark right?

D

It is possible to have multiple bookmarks in this case. I can have more than one bookmark to be able to tar for each bookmark to be possible to render erization of any content, right And when I say content,, it can be anyone,, it can be a video,. It can be an audio and image 3D models, model image, 2D models, 3D gif models. In case what imagination wants It is already based on location, right it uses world coordinates real to put the content right in the context.

D

Then users it can be free, moving freely right and I content associated with your location. It will be scaled according to your distance right. So, for example, if I put your your sat in the code that the that the object will appear here when I'm going to distance myself and the feeling I'm going to have that I'm, distancing myself from the object too, and here the image tracking that launched earlier this year is almost similar to the marker. That only that the difference is here because going back there,, right?

D

The issue of the marker I will be showing you,. It depends on some edges around it to be able to serve as a trigger so that the my camera can recognize that image. Already this image tracking, which is the iefp Right in English.

D

Sorry, sorry, the MST, which is in English right then it no longer depends on the edges. Understand I can be training any image there, the rjs library right she always appeared to her, right,. Whoever heard of this library in Java Script passes it on to augmented reality on the web in ten lines of html. So with 10 lines of HTML I can already have my own experience. I can be here, I, don't know. If those who don't know the library may be saying Wow,, but HTML is HTML, yes,.

D

The only thing I'm going to do here is to include the two subscribers, right, It's, just the necessary clips,.

D

There's that question I mentioned because by frame the rjs library it uses, Freio oxide is the one that is already basically pure JavaScript. So it's not using the devil written to make it easy and make it use and Gabriele myself I'm going to use the iPhon and right. Then he.

D

Joins me, putting the clips from there frame putting the script from my Bible, my rjs library I can be doing the rendering is from my first experience in augmented reality. This code here is a basic example of squats appearing as soon as the camera see the marker right then, like wow, very easy I. Remember it like. It was today right.

D

My first 10 girls in HTML when I did the rendering me when I saw the result, some Wow I don't want to stop studying anymore and that's how I I joined the world, no, it 's just that it doesn't bring all these facilities, right, from the rjs library I've been bringing the pros and cons is the pros, right because everything I 've already mentioned it really is bronze pros. So most current browsers, updated with the exception of iOS.

D

It 's just Safari on IOS but, for example, on Android on my Windows and on Linux any updated browser. It will work right. It's easy to For the developer, right, now,, there's a new documentation, note, right From the moment it turned into a rjs,. It's a wish when we made an improvement in the documentation,. It's even there available in the do. Tá contributed, we're with the next step of letting it just translate. He swims for other languages that he has incre se only in English, and then he supports Hi Fran, ou g to the standard.

D

So using the former prime minister I bring this facil ty right I bring this possi ility of doing an exper ment with HTML. Only he there are some purchases, right,. He doesn't have the dedicated support for the projects. So, who will be creating your project, doesn't have someone to be there helping and everything else,, even because everyone pays the price, right so,. As the colleague said about the first lecture,, it depends on the availability of the person right, but so the main point it is difficult for those who are not a developer right.

D

It requires knowledge of programming, mainly HTML, in what is HTML the knowledge of what Java script is,. You don't have to have the habit of reading documentation and tutorials, and like this issue of reading documentation, is something that we developers need and already trying to.

D

Start,, mainly, you have to build this Lego habit of reading documentation, And then how do I do it to democratize, right ah,, because if the teacher wants to, he's using this technology to create an experience in the classroom, that ah, the arts guy, right, the person who 's there doing his image gallery, you also want to use augmented reality to do something cool, understand, then, why not use the web, also understand to do it to be doing this And? Then it was the Italian, I didn't even put pighinelli,. He made this announcement, there, right,.

D

He did it on his own Twitter and in the middle calling for volunteers to be able to be creating the first. The first, the first platform right or prices of the authorship is augmented reality the web And. Then they came up with the a rjs studio, this print. When I got it,, it was still a little outdated,. It already has some updates And. Then we went I saw that thing Wow,. Why not help, right and so I am, as I said, I'm Junior, So I'm, starting really two years ago,, but I started in the area.

D

In the area must And, then I saw an opportunity. I thought Wow I want to be helping, because it was thanks to rjs that I entered at least must So I want people too. You can have this facility right, Hi and then, as I said,. The first platform was born,, the people, right,. It is still in the Beta version, right,. We made a schematization, right for the Raptor berfest, right, so there are several bugs there, right, open problems, inside.

D

from the platform in the river spill to be able to be using it, and we can already launch version. 11 already has the little babies right. It's with him. It's not with the studio. I can be building it publishing right, augmented reality. Without ne, no programming, knowledge, So guys,, with a few clicks on there, entering the site with some clients, she will be able to create it.

D

D

So,, what are we still studying to try to see what the problem is,, but as soon as anyone who can help will be very welcome, right,, the person can be choosing their own content and coordinates, right? automatically generated, and then at the end he has two options or get the file or the zipped file.

D

With the complete code And, then he can be opening this code on his own computer and he's seeing how it 's, like How the whole code works behind or else publish it directly in the Hobby animal to a certain Santana live site and I started to get into debt. To write about reality is a the a rjs Studio at portuguese right. ah Ok, so I started here, sorry and Google I. Don't know why she is. She thinks I'm staying I want to call her. That then I started. Writing right. About number must uncle So.

D

Whoever wants there is good, starting and little by little. They don't my days off. I'll, be writing more, right now, I already have a marker-based tutorial for using root, Hub right and then I'll be presenting it's time.

D

Priscila I know. If there's time I'm going to present it here for you, Saturday is there, from my number from Laje will be available. This website that I will be showing you I will not I will not generate it. I will I will create an option to download the code. Ok because I access it here, look.

D

I will put generating the I will not be generating the link through from hit Ruby, because it still has some rubbish And. Also because that question of the person when he is not a developer, maybe he may not have it.

D

Rcador right here and here's the Sérgio feedback button, a very simple thing: they didn't formulate so Anyone, who wants to be looking at, creating and wants to, is giving feedback advising her about a bug. You can initially feel comfortable the form It's in English, but it can be, can be answering in portuguese. Ok, guys, no problem there I'm going to start my construction here. We have a marker already the default marker right, but this way I can be uploading. An image of my own right here.

D

I already have an image that I downloaded he own ramp. Kit I'll have to be I'll need to download this one. This image is there. Let me save it here. There is this option and right here in Shoes, with sneakers right I'll be able to be offloading the is of my model or image that goes whatever. You want, I already downloaded here the zipped file of a kitten look at it, I love cats, so I'll always download this 3D model. Kitten. It!

D

Wasn't me that modeled it ok, people I, don't know I, don't know how to work ar still with 3D modeling I've already tried to change some things in Blender and everything else, but it's not I'm, not an expert, but then I present to you this platform right, it's Pole Google. It's basically like a library of 3D models. Ok, then I'll be able to use them. Most of them have a license. You understand to be using it 's, just a search. It's ok! So here I downloaded it I downloaded the e by 3D Look right here.

D

Where is this option to download me? I can be downloading it right. Then any format here 3D model. Even then look how I told you right, thanks,. You know the fgl This is what is possible in my browser, right,, the rendering of 3D graphics from 3D models, where I can be viewing in my own browser without needing It's installing the plugin or anything right like in the old days. It's. Ok, coming back here, it render render I'm here. If it's done it's because everything is ok with my model. So here look at export.

D

The project I have these two options, I even have the option of downloading mine from my package or it's publishing it on YouTube,. In this case, I'll be downloading. It right, I already downloaded it,. So that's why it appears here. I leave it or it's here, so the I didn't download it. I thought I had downloaded it for a long time,, not just a moment.

D

D

I'm opening it here just to show you the content is.

D

And it's over index da, it creates its files.

D

B

D

Then, just a moment, Andthen Andthen I was talking to what you think today open here. Look. It was already for me automatically all the right code. I opened it here, just to just to be able to put it showing you that I'm going to need this code here right all And then look at making the there is this this this platform here that is the glitz right, It's, a more friendly platform right for you're building, creating the code so I'm going here just to be showing you the right result.

D

Andthen, it.

D

's, just a mo mentto leave it here. Look I, think my internet got bad. Ok, now good, so I'll be taking the files right here that I don't need. The only thing I'm going to need is the HTML. My folder watch Andthen.

D

And, then, that one that code there, all that I came to me from do a rjs studio, I'm going to paste it right here, but before starting I have to see it here because right here in this option in this tag here the brand, right I'm going to be putting the go It's getting right to he. Where is my marker, right, then,, my trained marker- he comes right here. Just show him here.

D

Is right here, I'll see if there's a way to open it, just to show you it exists in time, but ok I'll bring him here right.

D

And inside here, I have my url that I need ok, I'm, going to copy it, and I just make this small change here this to this tag here, I need it I need it. Well, here, look it's including my model right there here. It is.

D

And it's something Hi and from there I can be I'm doing, and my test is the only thing I allow here right then it's ready. It appeared here. It's already in means that it's ok, this link here is the link. I'll need to be able to access it right and somewhere else, as I. Don't have the printed image right, because my teacher's ink has run out, I 'm, going to make the small one here.

D

And this is another website from the QR Code, Monkey and I may be creating the QR Code, right, we'll do it here quickly and the access to I don't know who wants to go testing it. You can test it. Ok, but you have to go there. You have to download that one just get it here where it was 's about there that image Andthere.

D

And put one next to the other, so you can Andthere.

D

A

Andthere Andthere.

A

Andthere, it's just now.

D

D

And the guys I think I'll owe this part to you in 1, already I'm going to owe this part.

D

Well. So whoever has the QR Code reader on their Smartphone just point there to the qr- code. Qr-Code there authorize the use of the camera EA from the moment it will open the browser EA from the moment we open it,, show the result, right From the moment it opens. The camera, then just tell this image that the image that we trained from YouTube And then it appears the 3D model- is showing up,.

D

It didn't work at all,. It owes this part Hi. It worked Oh, that's good, because it's for you to see how it is instantaneous right, That's, exactly what I knew would work, but I wanted to show you here. 's a small show, case, right,, one of the team members made this one,. He had this fantastic idea, right, to train, to put the QR Code, train inside the marker itself,. So whoever wants to is watching her Hit Ruby is hers? Is a woman Sorry? Whoever wants to is watching her Zap You can feel free,.

D

There's this show case there. Fantastic, to put it in here. Just for you to see the result and the result that it gives is just that,. This little dinosaur will appear, right,, wonderful and t itself her right. And then on social networks, right We already have Instagram,. I already have it, it's going to be from time to time, people are posting, right, on Instagram, on Instagram, about what's out there, right?.

D

Where there are more things that we can like, examples of using the JS air, where there are more examples and Linkedin, right, then, the buy it there,. If you filter by the hashtag noon noon and algés right in English,, it goes, you will be able to see the amount above a huge amount of examples from there using the library spread around the world, and here are all the references that I used, right.

D

I can be making it available later this month, Delaide that, then you will be able to see everything all the references, I used it and thank you very much I'm here. Whoever wants to have any questions can exhibition 1.

A

The mall there Ana Diva absolute everyone closed said the same thing queen of Thank, you very much to Daiana, went to concerts and presentations. There were a lot of questions about you,, it's in the chat and, as we have other lectures, what we want to do leave the questions for the end Because. Then we can discuss it at one and whoever wants to participate. Ask me directly to get to know your work. Ask a question directly, then we'll be a pleasure. Ok, ok, nothing! So guys Thanks for the can questions.

A

A chat well participate in the action with us is for you to ask directly Taiana it's for nothing, that's coming for the others you know and for Lucas, who will also be seeing you in a little while and now I would like to invite Hernandes to go there with us. Mateus hernán is the one who participated in our first event. He was interested in me talking to you.

A

He gives a lecture about things that he has many and at the same time, business and already has knowledge too, and the theme of today's errants is making peace with connected projects, and this theme for me is important because when I'm not developed vedora on a day-to-day basis, but when I did a web bootcamp, it says the web increase. One of the things I learned was usually from Who. Is a junior developer already enters a company to get the bomb right and usually these bombs are that I have already turned off.

A

So this theme, for me, is super interesting. I hope you like it too, and then I'll call Hernandes.

E

Andthen, thank you. Priscila is consuming Ok. Everything is ok, Ah ok, good night, everyone I hope you are well at home. I have my water bottle here, so I hope to have a baby in the water. It's also good to eat. One need it not me about making peace with pra Delegates. My name is Matheus Fernandes I'm, an instructor Natura also organizes beck Brasil. You came to find me on Twitter and on any wall, or my e-mail is at my username is steal. Elieu Ernandes is an interesting thing.

E

I wanted to comment on anyone who has had a problem submitting with Google Docs or any other another slide system. You can download your presentation six at the company, a lecture like here in PDF and Firefox itself. You can enter presentation mode, it's what I'm, using now it's much lighter than using Google Docs or consuming any the system. Of course it won't have the transition benefits of the console team. Much less. My computer's girlfriend Call those who use Firefox Chrome a lot etc. You know that memory is practically gold.

E

Right,, it's good I'm and become tough inside. That Brazil will be my Twitter and let someone want to follow me. The idea later I'll send the link later just take the opportunity to make a comment at the beginning, André. He talked about the security issue and also how to use almost all commissions with YouTube is a very interesting example. On the issue of options with the city. Your program that ends up in can turn into a shot in the foot.

E

Because options that give more security but end up bam, turning shot in the foot because they are optional. The person can move on whatsapp. There is a protagonist of the clip called to follow them. She is responsible to make connection with the database, so we know what is very serious is a serious thing for fill use and even one up to version five are wrong. What was released last year and this year I don't remember right. You could put some operators intact with the object or not And.

E

With that you, as it was optional, you could end up putting this one line in hand or put an object with the same value and key, and with that you run a serious risk of having SQL injection anywhere. You would have accepted user input directly in the intent before the clean, Caesar state, but there was still if risk and the secular team had already come up with a way to get around this problem of adjusting it,, but the staff wasn't adopting it because it was optional.

E

And then I just left an order, so here look, you can leave it optional today, but in the future we will give military, and today, in version six bleeding the last version version six is mandatory. You can't use the old s dex, where it allows management. God want t, so it's just an example for those cases of options that end up shooting themselves in the foot. The result It was a success that the staff managed to reverse and remove from the process everything good going back to today's lecture. Now is the question a lot.

E

I think. The best question for me to ask is why do I have worry about the rush connected because I have to worry about it, but you, let me ask you why we have to worry. He has to know what a legacy project is. We have to be able to recognize that it is a connected plate because they have several characteristics, including what I'm going to talk about? It's not written in normal silver, stone. They are small characteristics that you can detect in linked projects Like, for example, ours, our code, all our code.

E

It exists that we are not going to create the project. Now it will grow. Other people will start working on it and everyone who programs knows that, even if it is a one week project that is programming, even people would have been playing with the study as Taiana present just now, even if we are playing with anything on the weekend or on a daily basis, and they will appear from someone there. Oh I loved that I think message: ok, I'm, going Andthen.

E

What we talk about now, I'm just going to get the wrong one,. Just let me know.

E

What's up What's up And, that's.

E

It right now coming back Beauty. What is a legacy project Why do we have to worry about it, but he has to see what a legacy project has left search until the team. Dia has a great example just wikipedia like you, no later there's a giant text and it's boring and a giant text. I don't know about you, but I don't like it. I'm not a big fan of milk. This giant book type event see you later s anyway. So in short, why do we have to worry?

E

What is a legacy code is by the way, the best it is because a legacy code is bad, because a legacy project will even make its characteristics the main problem of a legacy credit of when it starts accumulating bugs so be in front of us created Now just a week. That's why I started playing now: either Ressurge I just downloaded I'm starting to play or a library, a new project of my company.

E

Do they will appear in any time for you having your breakfast quietly with your family at home, quiet and especially when it's broke when off work. Nobody can access the site. Finally, banks will appear and a linked phrase is normal or not normal. In fact, it's how we find bugs a lot of accumulated like crazy, accumulated even about 50 to 70 or more banks that are small. Were mine like ah let's not touch this today po, because it only affects one person, two people, a very small portion of users who rarely use it anyway.

E

They are a bunch if it will start accumulating And, then, for several different reasons. We may end up not being able to solve these banks, but this change is one of the characteristics. You can rest assured, which are just huge accumulations of banks. Ea. We can't keep up with the resolution of these banks, then what ends up being a little worse is that a legacy project is common for us to count the magic code that I can't male can't. Nobody knows what does is a code that does everything that logs in I wanted to account.

E

What day it was data in the database that sends e-mail what to do daddy to study. But no one knows what this code does. No one can understand what that code really does what it was written or at last. You can't understand what it does is show us main causes legacy.

E

As I learned commented just now, yes, I also went through a situation where I started with Junior already receiving in my first one to be a bomb to take for delegate I already think it looks like a legacy Worse I took it was a commercial building. Take three four, even with you I, remember the version, but it was 5 down. So it was a very old version and it won't stay. 17 had just been released, 7.1 and that thing that nobody in the company knew it could do Nobody wanted to change the project.

E

And, that's what's new in the company for unfortunately, I ended up forgetting that learning to work with the project is that they had a board hurts no one knew what to do. I. Remember how I used to take you a lot of head to get hold of the code. You had to open about seven, eight, nine ten, a place a function. Only then like it really was a code that was terrible to mess with, and the worst of all is that the more the code has more bugs and they get more magical.

E

It is harder to test further capture, bad guys it inside it, but you have to find a bunch inside our code and most of the time we may not even have unit tests. In reality, most of the time there aren't many volunteers or any kind of test, and that, even if we want to face it, it gets difficult because we have a lot of bugs. We don't know where to start to solve them right, Sometimes. We have to follow the entire flow of the company itself,.

E

It already has its future publication and we can't follow God with our mind, because there's a lot and there's a lot of code that they understand how it's done. And.

E

Then, if you put the two together, you have a code that you can't test, because you have a I, don't know: 5, 6, 7y, conditionals cases, side effects can happen inside the code and I kept, not understanding how to be able to test how to understand the code Oi and the worst thing is that maintenance is expensive, that is, when we have this project, even if it is working to provide maintenance ahead, cost dearly for us as a person, because it costs mental health to have to spend the night at night and call that coffee shop, Sharon, harlow energy drink.

E

That I had to be able to understand the code, hand it in right away. Then I kept forgetting we access with other people with the project itself and success with everything, because maintenance ends up with more expensive sleep for us to go to the company that ends up wasting time with the development of the project, with the maintenance of the project and cannot deliver Fitness of the new employees. On top of that, and as we commented now, it's just a matter of moving the project. This is the worst fact of having a legal deadline here.

E

Nobody wants to move, nobody wants to touch, nobody wants to pay attention. Nobody wants to do anything with this project Hi and then eventually, a terrible accident happens, which is to break the project and the worst. If you are full of bugs. If the code hurts no one understands how it can work right and it is hard to test and imagine what does this code break so it works. Nothing. People are going to do. What are we going to do things with the school and to get it back I to get it fixed Dom?

E

Some people will get it this week, I, don't care I, just don't care, because I 'm just going ask for the accounts of the company's work or I'll call from a project to anywhere anyway. They go through this summer. I. Don't need to worry about this project and the country has to think Well I, don't need to worry I. No I can't even leave my project that I'm starting today to reach this point. This project will never reach the wife to become a legacy.

E

There are a lot of bugs of having a poorly documented magic code and etc, but then we come to another problem, which is that we don't know how this becomes legacy still out. There understands that the sun in Brazil But. How can I know how this project will trigger legacy? What how can it end up becoming legacy or not?

E

We have some possible causes, there's a lot that can leave the flash on there's a lot that can leave there bugs leave the male code etc, and we have the possible causes that I think the main one is a short delivery time. We have a deadline course too short to deliver Sometimes. The company is in a hurry to deliver a new feature. We're there thinking. Why wait? I can't stop and write These cute codes, I write on the days I need the way they won't understand. I 'll!

E

Take it because they're pasted that crazy and that's it- the exams- are just too lazy to write beautiful code. It will be easy to read I'm too lazy to write good code Like. This makes you too lazy, because you have to think You have to program. You have to test delete what comes out of new and etc, and we often have problems that we don't know about and then whoever leaks to those who are cover for we go there.

E

Looking for how we did how to get out of vim and say copy, it's the same solution, so we Cláudio Sometimes, we end up, duplicating, choose and the same thing copying Claros to converter, sometimes in a hurry, precisely because we don't take the course to deliver things, what we're fed up with. They don't understand what code works. And, then our cut will get more and more macho, that is, we copy and paste code.

E

They don't understand that they find out what they do without they just know that it works, but it ends up becoming a problem cause there is a sound is turned on, because then you imagine who is working on the project today. I had a problem, I bought it from Nicole Bahls woke up. They work as a production touch in a month. You will come in my place and you will have to work on the projects it just stayed.

E

Bro I did everything in a hurry because I love, you short term, to deliver and I was too lazy to do things right. I accidentally went there I copied and pasted the code and crazy understand, I, understand And. Then, if you have a problem, you will want to talk to me. Just look I, don't know, I, don't know how it works. I, don't know why it's giving this error, and then it comes back to it.

E

Problem that takes longer for us to provide maintenance is expensive for the company to be able to maintain, and with that we end up with the relationship. Also with the lack of standardization in the project, that is, our project does not have a standard,, it does not have the standard of whether it is a working day, that is, it has not stopped. City has no written standard, does not have an execution standard and the project Each one. Does it his way so today, I do it my way.

E

Tomorrow we have a new person in my place about loving this project, and the person won't be able to understand what he's doing now, making love that comes fast I'll. Do it my way doesn't have pattern: I, don't have a pattern. I can't do it my way, and then our code It stays with me and a face me, a mine and an easy but beauty that what I do now I'm going to develop av2 I'm, going to delete everything and start from scratch. I gave up programmable from the diary.

E

What I'm going to do here is everything I do n't know what I do here. There's a very interesting point that this issue of developing av2 all comes from. That's why I spent it everyone dreams of this V2. Everyone has this wonderful idea of it's horrible singh? What to do?

E

Let's pay and let's do aside how to write from 0 only that ends up making more problems, for what kind of looks like a wonderful idea to us only that we can end up falling water safety, because unless the product has a drastic changes by unless the product of a lot of one, there was writing, erasing and doing everything 0. It won't change much because all our code that she's messing with today was done with another person who also had a tight deadline had to come at night to program there had to deliver.

E

The string taking place had to try to understand as much as he could to get the code delivered and make it work ie. It can just take the job of a person who turned two three nights to solve each problem. He had erases. This lady forgets: let's make it from scratch. We can't do that because we end up wasting more time,.

E

We end up resorting to the same books as that person who turned the night to solve, ended up passing him only because of that she came at night to sleep problem, so we end up staying in this infinite circle. We end up letting go and doing my God in heaven. How am I going to solve this problem? How am I going to do the? What can I do now to get to work with this project, not to hate it, even if it is a legacy and still keeping the same company that I am today good.

E

One thing that André said at the beginning is equivalent to a question of security when legacy phrases are that all code will become connected that at some point it will be like he said that the team will evolve to the machines computers, where the cell phone is worth it will be able to browser in those was all that we were using others. We will have, and consequently new problems we will have. We will have new problems regarding security regarding stability, performances, etc.

E

So, regardless of what we do project, but they ended up connected, but of course there are some things we can ask for, and that happens to prevent our snake from getting any nicer. They can ask that big problems like bugs accumulation or lack of standardization happen within our code. You can keep our copper pan Despite, it's been a while Hi guys, she's. Having problems is some Banks is starting the body stopped it exactly as we can for both sides.

E

We have an invitation relationship or with any system, and the name if you use glitter, passes some more used today. Some water here.

E

E

And we have a winch that everyone uses I, think almost everyone. Actually, we can give you r other versioning services, I, think I called myself main today, and normally we do n't care about us saying that call click there. On the repository put the cute name, put a description, Zinho put the video and put the license, plus some information that the repository column starts, waking up with a lot of peace, with a lot of peace with a lot of production by itself and that's it.

E

But we can add a pattern to our Beach as bitflow that some well-known patterns to use as capsulite people can standardize until our code works and stay easier for us to keep a part of our code stable or if we manage to suffer even more from the invitation versioning, we can kill a part of the state code we can separate and isolate. It happens that is being problematic, So that function. That is breaking, and nobody knows why. Talking to the mind, you are a little easier to isolate what is in pro duction or other functionalities.

E

If you can have several fronts of yours here of your product, working whether you are working on yours at home or whether you are working in your company having to work complete with 5 two three people or with 50 200 people, when we starts at four using, we can facilitate the workflow with our code And. In addition, we have good language practices and the building is using nowadays either as JS or with P or with let's go Rubi Júlia any language.

E

There is a work library that you want to look for us to beat good practices,. There will be people who started to create that or who started to use that right at the beginning with roasted chicken and went through a series of problems, and sometimes people like it and me. A good practice guide asks for the language of the project, library, etc. So.

E

There will be more people who have already overcome a project before and you can take advantage and follow people's tips to avoid that you have the months during my performance, I want to leave, etc. Besides, we have The style guides and I, don't know. If everyone knows there, it's called to connect to some languages. I already have this code ormatting by default, built in, y. U already have a team like the goal. Smt is other languages like PHP or Python in js700 does not have this formatting langu ge, but some have their own Their code.

E

Attern already documented as PHP h s a step I'm just mistaken to see the fathe. You have apepe apepe, 8 and or pick up pt in Mr. I'm wrong, I've been a little long time since I, don't move catch big in a highly 2014 company. But some languages have their own langu ge standard that has already been debated by peopl who work in the language. Yes and some anguages a little more versatile l ke. Sometimes we have some market standards, the market serial as a dengue code. Standard, we have the standard, I can use,.

E

In addition to people,. There are other factors that I I don't remember. Now it's And, then each language will have its own set of rules. I've already looked it up ahead. There's an accident that comes out allows us to not be as if we want to,, the father also takes it P they have their own rules But. They. They have different functions and projects that try to keep these rules within our project. That is, we have code rules,, we can use several. How do we call variable?

E

How do we put it; puts it doesn't put a period,? How do we define conditional if we put the name of the variable separated by Cássio by underscore, because the muqueise around is small things that we end up running on a daily basis to discuss to think about the phases not felt like I, don't like, but some even and standardized, and to improve the husband down to and tools to do that? The goal is an interesting example because it already has its own its own code style rules.

E

Yet it has an e his own function for his has interacted to check your code. You are following the Serginho output, so, yes, you will have inspector Zinho there in your code that will keep looking it works. You put it; can not put; here Or. You forgot to put this inverted conditional. Finally, we have these These functions or, if programs that are beautiful from the Simpsons use our code and follow the rules that we open or that the language itself knows yours.

E

We watch these TV streams, guide flow people style guide tool to use this certain people think of a very interesting thing. They want automation. We will always want automations. I am grateful intense, but everything I do nowadays and some things work wrong and automating is always good to automate help, but we have to do it very carefully because we can run into a problem- and this is an afternoon that I got on the Internet I. Don't remember the author. If anyone remembers, please send it to me, so I can believe it correctly.

E

It's one to be able to translate is basically in the first first graph. We have in the vertical line how much work we are going to put in and in the horizontal line, the we have the time to develop or to work, and then in theory, we have the original task that has this line like the median of an average work effort and then, after a while, it goes there and below. But when the we have to try automated then write a new code.

E

The idea here we spend more time writing WhatsApp code and then the time we spend on this function in this task will drop to almost zero or it will drop much smaller than if the difference making the hand only that automating always appears a good idea. Then we can always fall into the error. That is, we end up spending much more time our streamlining code than doing some tasks.

E

Sometimes it is much easier for you to open a new tab and just write slack.com to enter the site than you create a program that will run when yours manages to open that opens in your browser of choice and fan, birds make someone etc. Because. We've been through a lot. The time writing code we have to publicize the return we have to think we have to re-develop and we end up wasting a lot more time in this autumn, attempt WhatsApp what to actually do the task that we are not there So in that.

E

Second, we can see. There is the issue of work in the workstations it grows and comes and goes does not run with an imagination being that the normal work, if we were to execute task manually without trying the most Zap, this is not spending that much time. Another thing that is very important are the extra tests. 7 is boring. Rate is hard to do test in need, it's not worth it, etc. But it's something I read this week that passed me feeling here.

E

If the test is hard to write, there is a 99 percent chance of the test of being necessary that exactly where I am Test will make your father have his greatest value within the project, because, if it's difficult for us to test just by seeing your fine test, it's because I wasn't of the best, even if he is in the best possible state. In the best quality he has ever had, we don't need to test him, because if you can't get a kit, we can be sure he's studying and that's a cliché that is easier.

E

We know that the code broke. What to expect the main customer of the company. The gift that pays the company, the most Call complaining phosphoric is broken, is not working. I can't loop application and, whenever possible, elevate, the code is a function, is a variable, a conditional always reinforce the code a but refactoring. I have to write. I have to spend more time refactoring. How can I bill what I want refactoring if I need our place weather, not good.

E

The default definition of refactoring is the process of changing the code, just right that is the Speed size, despi e, changing the code that already exist, , changing its behavior, that s, before refactoring a function,. We ch nge the code inside it, but the code continues to work, and here it is worth mentioning that refactoring I'm trying to write different from rewriting our planet so just paste.

E

My task So there's a new function in the X-File when we have two more in this file functions, is that the pocket, the two functions for me, and eventually the two functions- are a little so little difficult to understand. So the code is so beautiful. It is not the day. I like it I go back. There I go there and factor the function uses the variable name, changes conditional and I made any mini changes. You want to this string to make it minimally more readable.

E

Already has a reformulation already has something that will either help you tomorrow or after or under the person who was working with you tomorrow or after that will have to mess with this code And then, let's go to the points that is to avoid programming oriented to gambiarra. I talked before about copying and pasting, with the covert and sitting in the mind. This is a thing that we can stop. Doing, I do n't stop doing it, whenever I need to copy and paste the Saber codes.

E

It was the second year it 's just that we have to be careful to avoid programming oriented to the famous coke or extreme go horse gambiarra for those who already recognize it is ideal or best of all is that we always understand the code we have today. So if I have a problem and I go to your color I find a solution. I copy and paste it's working go from production, I'll mark it. Catarina is finished, no I'm going to stop I'm going to read the code to know how the console works soon.

E

The print will show a terminal that it's doing to make sure how my code is working, how to choose the top. What bag is working and, if possible, to that you can even refactor this month. The cut people got to know why usually or not answering Someone knows who I am. We don't have it most of the time in a very rich context, for us to be able to know and set up a good example out the person.

E

So this ends up using pseudocode or a very different case, and sometimes we have to copy and paste the code in the name of the input and output, variable, etc, and the alcoholics take care we always fix. This is our code, but only understand what he was, what he does, how he does what he has done for us. We are a headache in the future and one thing that ends up becoming a controversy from time to time, for us is to document the code.

E

No, yes, put those comments at the beginning, the function explaining that the committee made it clear that we have to use this with a lot of common sense, because we don't need to declare a variable equal to age and put a date or just a variable Satan, but don't put the date because, sometimes, depending from the context of variable variable functions, it is all around your code and you can already deduce that it is always good and ends up bringing a very large value. Our current application documents.

E

Our code is for other people who are joining our project or for that Junior person who is joining today is starting to work on our project, or you call people who will be working on this one in a month In a week and for sure we won't remind the parents that we made I. Don't remember code I wrote last week last month.

E

Can it be so if the document that code, when I come back from reading that comment, I, don't know exactly what you 're doing, and it's even better that we did it in the project because very much the documentation tool for code can and leave. Comment on your code generate a cute HTML, so you can send as many people to access and people understand our code.

E

Colors HTML makes it easier for people to know where the codes are and it becomes a reference in the its your project, so I'm just entering the next new one today and there's a documentation and I'm moving a task that I need you, r, the Office of the registered and logged in user I can open the documentation there. That I will need to use login or some keyword that leads me to Haloween. I can find out if there is already somewhere.

E

That does this, and it also makes it easier for me to refactor the code, because if I look, for example of code in the documentation, it even a place that does this, I can very well take advantage of that claudiu I can eat myself call the way what was left o library pack of seven files like I'll, let you know ok, hi hi. I can know that cut That way. I can separate the WhatsApp world re-invoice and then use com in both places. Whatever our context, is,.

E

It's something that I, don't think is presented so much by people when they talk about code, review and score quality is that we need to review and not even the code people. This is something that a colleague of mine, told me in 2018 2017 in the second job I had in technology is I was being mu, ito, giving an ipega library, folks, lady,, take a look at the source code and see how it works and we'll know, because the documentation wasn't the best and I couldn't understand how to use that library.

E

What I did I had to download the project? It is the source code and it turns out that this became a good practice and I. Consider it a good practice to be something I usually do nowadays, which is always the source code of what I'm, using even if I'm, creating an application similar to moto in this application that I'm waiting for and I'm going to look at the source code look at the documentation, but my look at the source code, the dependencies like I in the middle function. How do I treat Lucas?

E

How was I this specific function? How do I trace defined that thing and so on? When you can read people's code, you understand and learn how many people develop similar problems on different fronts. What makes us today an example: I had recently I created the biotechtown side from law is to work plan, another answer to be able to work with Diego made ml, SP, tonsils, etc. I had several problems in terms of encoding implementation, you implementation of files, etc and analyzing.

E

Other libraries that had a similar work, I managed to solve the problem in a very simple way, feel like they are racking their brains for days and days and days to imagine a solution that someone else managed to solve, sometimes in a simplified way or a better way. Then, whenever possible, go there understand the code for a little while 15 minutes for you that I don't design, listen to the code by the Ruby kit itself. You can fill your eyes with the code browsing is the bug.

E

Has a new or traditional function, new function for you Navigate to among the code definitions, and it helps a lot for you to review other people's car, and although people of all these p points of code quality, we remember that we know how people who program what and what forms are necessary in know that a good code,, readable, code,, tested,, well documented,, etc. has a much higher value.

E

functionalities only that in the company this doesn't make sense, sometimes for the company. It won't do much, feeling. So all this care spending more time, refactoring writing a test with a meeting about paying for code about how far the gaucho followed. So we end up having to take us,. We end up having this problem of having to take our all to everyone. There, God, not that we have about code quality for the company So.

E

It ends up and ends up falling short, saying: that's how we can tell the company that code quality is good, that it will bring benefits or what benefits code quality brings to the company will see. People have to talk to people, pr, oduct or consciously or sometimes even against you,, but the refactoring makes a great new company. That is, the code is easier for me.

E

I think there are many, many small steps that we have to take, but when we put everything together, it can be easier to read the performer more it becomes safer or if we spend less resources, then less money goes to resources and more money can go to the salary increase.

E

The dust of finally and the company pocket can go to new company initiatives, our products we have to sleep with performances, a performance we have colony as long as it arrives, to maintain the project, because you are not well documented,, it is well tested and there is not so much magic code, so we can arrive and solve a problem more easily manages to account and your city and the workers funny two three four five nights trying to program to solve this problem.

E

Andthen well then, if Whenever possible talk to people who are also programming and try to establish What are the high points. The key points of code quality within your project is I. Can't give you a straight list right now of what quality code is getting your company, because it changes from product to product Sometimes.

E

There are products that work a lot with require a lot of thought, resources and the code quality will bring a great gain in performance, and so from a point that you can take it, but it is without products that don't use performance so much So. If you talk about Performance in code quality, making sense of the company, then the ideal is to recognize.

E

What are the Key points, quality, refactoring code? You have to maintain and talking to the team you can know which are the points that bring the most benefits for the company and I'm talking directly about money, because it's exactly what will end up helping the company what and it will end up giving that priority alarm for most people and despite all this Andthen I'll, be here like this. Despite everything, we have to put food on the table I with the provider or you are watching at home.

E

We work with us there's a life outside of work outside the code. We have a family, we have a son, we have brothers, sisters, father and mother, grandmother, grandfather uncle and play go to this Milanese block. We have to work, we have Hobby are Mental Health to take care of, especially the moment we are living through. People have to eat will make health difficult, both physical and mental, emotional, etc. We have several things new forms of life that we have to take care of, and we know how to find some You must know.

E

Most must know how a company with asks for an environment or concrete bad can end up affecting your life either, because I'll have to come at night. I. Don't know why you end up stressing about people in your company organization with capricorn. Is this one stress everyone can end up trying to improve the code at what time do we get stuck in a circle that starts to work? Duh, I'm fed up with this code. I don't want to mess with it anymore, I'm going to quit I'm going to kill everyone.

E

If I said this ends the day, people go home, sleep rest eat, come back in the morning same thing, look at the same code that no one has money is getting it works. It ends up over time. It ends up getting stressful hours of programming technology mara, a lot of people that people does anyone know how much sooner this is the. How much of a problem answer to make for us, mainly mental health problem is so we know that there are. We have about these points only that it comes back part of your life.

E

I think I give it to everyone and don't get stuck forever in your work. I already had cases that I have already joined the company with a terrible project that I tried to help improve I liked the project I had I dreamed of leaving me the plant good friend, perfume r, the constants. It was just that it's true everything has a mental health and I know how annoying it is. Especially, you can't improve your affection. You have to keep working on a terrible project that you don't like to mess with, that.

E

You can't work with anyway, a minimum of leisure, a minimum of respect for yourself So despite the good sweets. It is worth mentioning that you can very well look for your job and if you can't take the numbers from work and you can't improve your own life with it, I recommend you looking for a job look for other vacancies. Until today we have a lot of service vacancies in Brazil. So if you are going through so many problems, you don't have food or less company. The company does not accept this improvement of these quality improvements.

E

Code. Don't worry, your head is looking for employment companies. We will have health Jennifer, they will end someday and not even the police have to live for the company So. If possible. Look for a company look for more vacancies. I know that this is not always wrong. It is feasible for Maria people, but there is one thing that we have to remember that for us it is easy she just eat and if I go to the crust company I tell companies that are they pay more or less than Pay me Less.

E

You will give me a better quality of work or the same so I can't let go of a good weekend,. You have to spend the weekend in the hospital or stressed without being able to rest, and that's it and I have to this summary screen. I'll leave the link for you two there and you can look later, but this is the complete summary of all these points that I decided here who it.

C

E

Ah Ok, ok, ok, attention of all the points. I said that sucks practice, language, Lottery framework, etc. We have hotel Factor ep, which is a site. Even a little famous has two factors or more even good practices. You can be solidification, antibac, front and Efraim etc. Know if the code standards are always con.

E

Vite e, be com is connected about style, always influxes, a care but criticizes the teeth of your project, even your company, because, with the flow you manage to prevent unexpected things from happening things that no one knows why happen with this cut of the people who work with you either the library you use or the code, the person is working with you. The person is on the other side of the screen.

E

Working with you write a lot of unit tests in friend, integration and setra write the text that will help you Especially when you think I didn't do it test because the code is boring or when you don't want to do it or you're lazy, because it's difficult and also the points are difficult for us. The others test documents the code Forget.

E

This story about the code looks when you need a comment is a fallacy, because people tell me that if you need to put main comments, the code is because I'm together, ok- and it's not, let's tell the truth, because sometimes the code is complex,, there's no way. We can get an indication algorithm and not comment on the code, because we think that just because it's hard to understand, it's because the code is bad, Sometimes, it's appropriate for the company's business, the company or the project, is difficult.

E

Ah It's just to close now, I give a lot of rope. The repertoire is always possible and drink water, whose health is that, if you have it in the group, you can have him put it in the final together with the guys later, I use a Pri I'm done like this I couldn't answer in the chat now Andthen.

A

Andthen I 'm, just remembering thank you so much for the lecture and for the jica. It's because of the topic, the term that now I'm going to use direct object to gambiarra and they said it asks that it has to come out loud. I thought that closed Thank, you very much for participating for the tips that you don't know.

A

Excellent and I, don't know, but questions for you later during the personal chat that had a question back there for us to talk more during the s, a Thank you very much and we Hi and now let's continue so if you were here earlier today, you saw that we had some technical problems because, after all, we are part of the technology. Hour happens, but we recovered and we want to bring I, went back to talk a little about mpm and he's back ready to kill, come on Rui.

C

Cold I came back to stay now,, it's okay, because if it doesn't,, it's also going to happen just answer the chat, questions or explain a little more without the slides it is, but so without further ado, let's talk about good things. Right, Let's be serious. People is that it is the latest version of msn, and here once again are a reminder of how you are going to install version 7.

C

If you don't have it yet installing it is already part of the PSB with 15, but when I had managed to say, this, Lux would join it here with the site,. Only that I had prepared it, I just had to do a small project that could show the exam for each command. Then we have our little project here, right, I, think now, dog, and now it worked just fine and even because it is very difficult to limit the command. It is already difficult to talk to him in front of us with an example.

C

If there was nothing- and he was left with a lost, so here is an example that I I said so much about the other time and that we couldn't have your side at that time. If you have any from Morro It's, basically a survey, it's part of the BPM and basically there's no more- is that an example.

C

I defined more than one package gave that one and the one here, Rio de Janeiro, returned from So he's using the language with a general,, an associate director, which in this case, is just to generate a new project again here and there and it's going to hit more,. The time is what it already did, right in this case, here it is.. We won't spend any power to put information about. This project will be generated and with that he talks about a military installation at the end here now we can see how they can learn.

C

The much less pollution in the Auto Po This is what happens in the command there, right then,, it's just a progress bar and at the end, you have a summary of the installation, right.

C

C

Oil, we're already the Mago's doctor,. So another example because I wanted to show the 500 ml is also not the best,, so I'm going to show you something that is installed Lúcia project in that one , taking it, right, I know if I do it in the TM list here, I 'll see that now and it's in this city. The difference there with the previous garbage is that we show only the first level of installed.

C

Packages are the altitude which is more useful, like this standard method, and we are here, we were so used to ourselves without using it. He has deserves so up that equal to zero is the whole community using that, but he decided to have lunch to make it his standard now, but everyone we did got it wrong before taking the truth out It's behind a kitchen.

C

If you want to behave, if you call me not even making smooth cream upwards or the ML na And, then he'll be all his packages even practically the same as he was even he has 61 good. So, let's move on here to a few more examples of what I. Also put here, the type of funk was he has to talk about. It was also a little improved with this version.

C

Now we list by URL, and we also fix the hydration issue there, which are age, and there is something that it did, but it doesn't work in selling and in the month users are also more pleasant. They have different colors to give the RL. It also needs to be better there from the contributing house than what you really want to visit.

C

When you use this information, right, then it gets more cute There in the real terminal than in that little video, but I also wanted to lift this ball there, and here an example, is actually a demonstration here to show how the audio that I order you with has changed what the audio is, I, don't know how you do the mother's day-to-day in Portuguese, 1 Ah ok,. There's no need here for a package that has a reality.

C

André is doing and that we saw earlier that it must have and get to know this one skill there at the base of the BPM and when we are talking, we almost see that there are two open vulnerabilities.

C

Now we have found and know if the version that has a problem so when we return the cream to the order that we were used to in the past, I was a feedback that we had the community. Also, a lot of people brought that we that the one with the type of table that I had before it was very difficult to read when ashamed to go up your Chrome.

C

Some information comes to me, so it went well Work enough here to try to solve the male and also not to do the vulnerability multiplication here that we used to do before. Actually now you only see the number of really the same open skills with. If you got it. go installed and not necessarily every time it was used, we would multiply. It was very large on the market, so we hope it will be more useful for the community. This is the kind of a little more beautiful with this one.

C

At the end, even the like here, demonstrating once again a novelty to remove the oil that we also used an option: mk5 Box. That will actually try to correct that thing. Actually, even updating versions that sometimes felt compatible with women are kind of right So. In this case, we see that no example. I did the ms in the middle of that day, because I had it installed before, and I can see that it actually installed a version 1.0 which fixed the problem I had of vulnerability and but potentially can cause problems in the string.

C

Then policy behind the form option. Right,. It's always an option so we'll understand. What are the changes and more that we can help a lot personally that we have something that we The goal is to make a lot of Almeida go up when there is actually a new version, Donald s, the truth, the height he is almost. He just wants to communicate that he is no longer good at that previous spend Donald s, so sometimes it ends up being a hand in the wheel and will be able to make it easier.

C

The work of updating dependency really Mainly when you have to send it in fact, look and here now another example that I have. That is one of the important things Also. Those who are sensitive and now went back to install going to bed on. These is not the default, so here in my example, I am showing that there was nothing in the background. I saw it here in my installation, Adriana and here I am showing information about this package. You saw that it is a package.

C

I use a woman to be able to create the t. How did it get online? There? I am just showing that there is a fan to eat a turkey, it's his one. So when I turn a year old by the sun installing this little package, he will be a woman who is pressing him. He will.

C

Declare as dependent on his project I want to be able to consume another project. That sometimes has this like. The mask is shared of. What's all, but in fact it's necessarily using it directly in your application. So it's the big change that doesn't work faces and And then I wanted to put it too, but it kitchen is to get better to talk about it.

C

And then, here it's actually the last time like more complex cut. Let's go that is also the Fit vehicle. It's sunny more waiting, even not that I don't have to implement us. Finally, during the conversation 17 so here for to verify, this, I ran my test command because it is running the Zinho script that is inside it very beautiful that it feels there and then I am creating a chat here, a package in the workspace within my Fala Brasil project, and then you can see that I wanted a pact. Here,, that's it,!

C

This package, I 'll, find a way,. He didn't call and I'll first put it here,, which is what was associated with best friend. And. Then you also or create the file here, I. Still don't have to go, I just put as an example here, a customized message that we will be able to consume it in the main package, put it in the case speaks Brazil, not even here.

C

That is the important moment that is really when we go in Peter Jackson of our project that now we have support for the key of the countries right, it's true. It's this one to them that can be In fact. It's strange that it can be the way to it packages there inside your project, that you want it to be understood while 18 items or and also accepts Gloria, that I will use here an example that really defined a folder and use É*.

C

He will see all the cults of the aspects that are afraid he will try to read as another did and to talk a little more than A Turma Da Lógica of mine. It only needs this key, the effect of the agile library, and it only needs the Cups inside the defined there. It has a really that lets me also know how to understand here for you to clean in the case here. I did an installation after the result, Fala Brasil. How is it right so now I also show self post here, sick, they Fala Brasil.

C

You can see that it is actually a link to Brazil prayer. One, as you wish is the link directly to my wordpress .com define is the one that speaks Brazil So now I can use it within my project, which is this here, is the thing Sometimes. Those who are not so used to what functionalism did right. There are sometimes actually saying that he series doesn't have a skill.

It's the main thing now I'm going to use my package I can make a record it really, while only speaking Brazil, as it really was a package that I had actually brought from the record. It's not and it's easy to publish it later and be consumed by the people. It is the pattern that many for this person already use I'm here in the case I'm using my Fábio now with the direct record KL and when Robson He must be I, see now that I have this, the other one who had before and also speaks Brazil.

C

No. This is an example, so it was really to be able to take the course because I ended up spending more time and before,, but here's the important message if you haven't tried it yet lpm is o class me gnp, M@ seriously, to be able to try this new one and feel free to send feedback. You client of our mpl repository patience there in the video and If anyone wants to hire directly on Twitter I'm, the guava outfit um That's. It now I, don't know who comes after, but a lot.

C

Thank you for your patience and faith.

A

A

I've already been, thank you very much. Thank you for your patience and for the technical support that you yourself are.

D

A

Right And contributed there just learn more about it has seven, it was excellent. Thank you and guys, just to remind you we're going be all available in the one after you finish receiving, then Lucas is coming. So if you have any questions for the speakers who have already spoken or for me another the other knowledge or for Lucas who will come in a little while and there with an agent on the nails we will talk already say face to face with you and now.

A

I have a great satisfaction and pleasure in introducing Lucas I learned about mare language, a little bit. I happened to LinkedIn, because I saw that it was a repository on Saturday. They are receiving several stars and I thought it was a very cool project, but when I saw that it was a programming, language and Portuguese created by students, I thought it was the best theme for october in celebration of cooberfest to Espírito Universitário.

A

So you Lucas and the water language.

E

People for Lucas all the best Have a good night. Everyone and I have here a little bit to talk about what water language is, right. I would first like to thank you. Someone loves you, and especially Priscila, for the invitation. It's a great pleasure to be here talking a little about one of the most amazing projects. I've ever participated that I've had opportunity to create. So it's a huge pleasure right.

E

First of all, I want to introduce myself I 'm, the creator of the ruler language and today, I also like estagiario.net at Stefanini, Brasil and, like Priscila, says I'm, a computer engineering student at stabilizing and this project. He has this university course today. I am not the one who maintains it. We have a team of five developers and he takes care of one of the projects later on. We will talk a little bit about it, and the first thing, I have to say, is about what is the purpose of our below?

E

What is the proposal, the proposal to bring to everyone a simple and modern programming right. Our focus is the programming beginners, who have several barriers until you get to software development learning and the people just want to stop and numbers of these Barriers to bring a highly simple and totally modern programming,. First of all, it is presenting a a little bit of our website for those who want to access mare and Tec, and this is the first look at it,. It's super simple. We have three buttons directly, one that takes you to our documentation,.

E

The second that takes you to our idea is that it works completely online and the third button that takes you to our burial organization, where you can find the open source of our language, the open source of the open source. Finding of everything we have to offer today, right, showing a little bit about how the water language is, what yeah And.

E

Why does it have this purpose of this modern Yes them I brought here an example in which we have a code of it in Portuguese and brought it in orienta, bringing the object orientation right, which is something that is lacking today in numerous languages that have the its location, in general, terms,, the very languages that we already have Portu uese, that does not support objec orientation languages that we have oth r languages and There are others in other languages such as Spanish,.

E

So we are here to show why w are simple, moder people and bringing a little bit of the histo y of the creation of our langu ge,. It appeared there more or less in Au ust-September of 2019 a subject called self-mutilated equals to college. Initially it came up with the idea of an exercise and had the first versi n created a lexical partner in JavaS ript called X1 So. It came up still in English and without any purpose and l ttle readable, we didn't have t no purpose at the time. I started.

E

I had a purpose. I had no vision of it. And then time passed, we had new members of the EA language. We were able to shape a little better, the focus we would have until around April of 2020 we launched version 1.1 of the language,. It was already in Portuguese,. We already had this for the Educational pit for beginners and it had a very high visibility compared to the other languages life easier for many begin ers in the field of programming, but befor continuing talking about the mare, anguage Nowadays.

E

We have a multi ude of technologies and languages,, as we can see here in this examp e, and why hey h y? There is someday a program in water.

E

What is the differential of the water language and why would I like to start with mare and not start with another language like So I will close any other Peu and the first difference that we bring is the breaking of the barrier in installation of our compiler, which is actually an interpreter, and we work the language works completely on the web through a platform that we affectionately call the mare idea, and it has more or less this little face that you are seeing and it works completely online, thus dispensing with any need for installation.

E

So we end up skipping the barriers that we would have to have. The teacher speak in the classroom. There install the language compiler and the idea of such a language when ou are starting in programming. You h, ve, no idea what an adult body that is an idea is me myself when I did m first progr mming cycle in college. I had no idea in the first class and install the C language buyer on your computer, so that you can do an exercise in the discipline So.

E

This first barrier breaking is something that we have always prioritized and let's say that we ended up bringing it completely on the web, right?, and the second barrier that we broke by bringing this language into Portuguese is precisely to remove this language barrier.

E

But then the question that remains is precisely how dividing one can help newbies in the world of programming, because since we are so used to it, English interlanguages ython itself arranged its Sharp like Java, because bringing something in Portu uese is one of the bases that we had f r to substantiate this decision were that several researches show and still show that a small portion of the Brazilian population is and This makes it very difficult because it took no. Despite we already have a series of documentation translated into Portuguese.

E

Some things are still not fully localized, so the we wanted to bring this structure of location. We wanted to give this cultural trait that has both in Brazilian terms and in Pará,, since ours in Iguaçu was created here in Belém do Pará So. This was the one in this. This was the main trigger and it gave for us the opportunity to say we need to have a website in Portuguese.

E

We want to bring leads in Portuguese, because we are in fact going to solve a problem, and that is the problem is that we are trying to solve it and trying daily in the continuous development of the language, and we always like to remember a phrase that Steve Jobs said that everyone should learn to program a computer, because it teaches you to think Hi and we have,. Today as a computing student,, we realize that the structure is computational.

E

Reasoning, a little more grounded,, a little more direct and linear for solving countless problems, right And. If we stop to think today, thinking is not only computational thinking,, a computational structure is present in almost everything in our life,. All areas need a branch of technology linked to it,. We have a very important example is bioinformatics..

E

I was a scientific initiation student working in the computer lab all the time,, bringing this balance between computing,, programming, and biology,, so two areas that when I was in high school, I had no idea they were related, and then I went u In today's very related impact,. We have an end to a series of Other day-to-day applications of technology.

E

Today we live in a pandemic time and it's very cool to see a series of data analysis to try to find better solutions for people to survive using data science, seeing which places have the most infected where, where the government can insert directly with more beds, forcing a much greater social distance So. We have this present a lot in our lives, and that is why we value having technology among us.. We iphan talking a little bit about the language, now above our code.

E

It is all open, we keep it in the Ruby kit, although we have a development team that takes care of it, we are, shall we say, the fixed ones, but we also have you external contributions and not for our language and also for our documentation in Raptor time well closes. We are also participating, ok, accepting flash in the crowd, because I think they make sense forever. It's improving our language, not only from our biases, but with the help of other people.

E

This is very important since we don't make the language for ourselves since the we make the language for people to use. So it is very important for us to have this direct contact. We also like to remember that around the end of August, when we started to receive a series of stars knock me down, we entered the Beach Hand with those from the 12th most famous repository in the world that day, and we were in 1st place in Brazil for three days. So it was something really amazing for us to see this actually happen right.

E

So it's open You can find it on Koch up there. Eva contitech You can get there next Ruby and be able to help us, right, contribute with us. This 5th, showing a little of the language here. I'll show you a little that we actually have syntax today,. It exists in the language,. We have it here. Initially, an example is the creation of a variable name and it is assigned a streaky, right,.

E

Our variables need to be declared, but they are static, and you tell the language to write in the screen literally saying write, so we think the readability is very big and right below. We have an example of a function.

E

Our classic example function to show double a number where you get this number a function you just need to say function is assigned, was a variable called result multiplies by 2, and when you give the return, you say return then, and it has a very high readability right in direct terms and showing a little new, our mare idea.

E

Here we have a code example in orientation to objects, right since we brought this proposal of third modernity and always keep current aspects of programming languages, since the g We have object orientation today without the most used paradigms. We brought this to our language. We have already heard many questions related to functional programming. We think about risk one day, but I wouldn't say it will be next month. I think yesterday for us to base this idea more to bring the functional paradigm to our language.

E

So here, as you can see the readability again in our language, that we have a class called animal and at the moment we create an inheritance called dog of this animal house. We basically say that the dog class inherits good, so keep this legibility. This one you can read drained in portuguese. We have a location which is something very important.

E

This tape, a lot for those who are starting right, It, is no longer a lot of structured command, loose and starts to make a logical sense, and here another example showing a piece of code snippet defines and static. That was a work that we had in college in advanced algorithms and we did in the languages he teacher sent and also has this roposal to bring this to make you angry to say: look,, it's possible,, we, the l nguage, is mature enoug to reproducing exercises that we have in college.

E

So this is very, very important for us. It is very important to have this level of maturity in the language. To act. Is the terms of technology stock. What we use the language to all those who have JavaScript right using increasing my GPS is we can run it locally.

E

We can run it there as I'll talk about it a little later, but for those who know dieese the same code that I didn't come runs, our browser doesn't run So how we wanted to have this structure that worked statically in the browser, so that we would n't need to have a cloud provider running all the time in the afternoon, which would make it very expensive. our application, and it would make it unfeasible to happen,. We worry about bringing this conventional JavaScript that runs in our browser.

E

And, then, for that we used a sensational tool called a browser with the code editor we use coldflash, but not pure it. We took the code from Cold fresh Air Ok and made some modifications to fit our needs and, along with all that, that makes the whole gear run.

E

Underneath is the hit Rehab Ethical as our continuous integration tool, so that the we can make our invitation to do the Quest there for Márcia, and it goes straight to the server and is instantly available to everyone,, so that no one is left behind in terms of language version, and it is a compiled language, right. It would be a little serious, very complicated for us to bring a structure compiled by the browser. So we said we are going to keep the interpreter works under the covers and a little more, it's simple.

E

We can abstract a series of things like the garbage collector. We can abstract the direct connection with the Chipset model of your computer, so we wouldn't have a series of problems and we're going to interpret what the things will work. Just as I had said, we work on the command line as we had. We always had it as a focus for those who are starting in the language, but often someone who had programmed time knowing the language wanted to understand how it was and always I said Wow, but it doesn't run locally.

E

I can't run it on my command line and we chose to say now you can and it's in the hypeness today you can install it in a Global way, with this command line on Linux, you need it with the deaf right, but on Windows you can do this directly and it works as a terminal structure very similar to the one.

E

So for those who know and have here, A light print of it t it's running on my computer, right All, this structure, in which I make the bad situation and Gir mare right after that I just call mare, and it opens the console. Currently, this print in particular, is from version 1.0.4.

E

Well, so the we already have a small improvement in relation to this version today, but it is very similar so and buying to talk a little more about the language. It would be impossible for us to have a programming language without documentation So. Today we maintain documentation that not only there is the documentation of the language, but we Lisa also explain and explain. Some concepts is that we have in the programming language. What a class is What is an inheritance. Then what is a constructor So?

E

We have what manthey this is all in a documentation and that you can also access from our website. So the point until now was done entirely in WordPress. The code is available in rit Rami and we also use it as a tool. Continuous Integration, nt, Kubitschek, Chan But in this special case for our documentation. We also use Charles And then help us to make some gifts that are necessary and, first of all and I would like to thank everyone for accessing our site. Water.

E

Tech and we have the name of our entire development team here, so you can get to know them better,, we'll all get together later, so we can talk to each other better about the future plans of the language, like the things are happening and I'll wait for you. There beauty, that's it. We.

A

Thank you And there And there is Lucas. Thank you very much and excellent for your presentation with many people that you agreed to clean ours inside. Thank you very much. Thank you very much. Thank you very much and guys in the chat. Ok, everything impressed, there are people who are going to install language right now so head on and on and.

E

On Thanks Priscila So.

A

Guys,, thank you very much for your participation. I wanted to share with you quickly the end here of our event. Let me put it here. Good and I also wanted to share it with you. Here. Ok happening in the future of hip hop and regarding events is, as you may be aware, we have someone angry Universe, also arriving on December 8th bread from December, 8th to December 10th. The event will be in English to access.

A

This link, I tell you Universo.com, and we have plans to hold an event on December 15th again in Portuguese like this event, but like the different theme, because December is the month of vacation month of holiday and everything else stay tuned on Twitter he tells you is that we will always disclose when our events will take place and If. There is any kind of change in the date, but at first it is December 15th. Even next time I can Twitter and, as I had promised or before is if you forgot interest in participating as speakers.

A

The next events we would love to have more members of the Brazilian community participate with us. If you have any feedback or idea or suggestion for our own upcoming events, send me an email. It's because Sofia, my user bit of and more and more other platforms, can tell me and send an e-mail,. You can come talk to us at the same time and we'll give you more information or if you know someone who is working on the cool project and it's worth sharing with the community,.

A

Tell us too and we'll get in touch here is the link for us to participate in the one that all today's speakers will participate as well as works and other co- workers. We would love to meet with you for the blue one that we can exchange an idea, and thank you very much once again for participating. Thank you for the patience. Everyone raises, the techniques that we had today, so life we were in techn logy happens, but thanks for the patie ce for the participation- and we are t en blue beyond.
