From YouTube: Tech Talks @ Kinvolk: An Introduction to casync by Lennart Poettering

Description

Lennart Poettering, creator of PulseAudio, Avahi, systemd, and currently a Senior Software Engineer at Red Hat, stopped by the Linux Technologies Meetup on July 13th to give a debut talk about his new project, casync. casync is an instrument used for efficient image synchronization for IoT, containers, VMs and backups.

This new tool combines the rsync algorithm with the idea of git's content addressable filesystem, in order to implement fast and efficient disk image and file system tree synchronization, taking benefit of the similarity of data. With a focus on simplicity, reproducibility, security, efficiency and metadata minimalism it's supposed to become a useful tool for everybody who needs to synchronize disk images or file system trees over IP networks in high frequencies, for example to implement IoT, container, VM or backup systems. The tool is designed to be friendly to HTTP for data delivery, in particular when used with CDNs.

Speaker: Lennart Poettering
Lennart is currently Senior Software Engineer at Red Hat. He is a German free-software engineer known for his work on PulseAudio, a sound server, Avahi, an implementation of the zeroconf protocol for network device discovery, and systemd, an alternative to the System V init daemon.

A

Do you think it's something I've been working on for couple months and isn't.

A

First announcement like two weeks ago and yeah this my first talk about it.

A

Yeah conversations that made it to my face positive and dancing is a new tool.

A

That is very much like a lot of other tools, but also very different yeah. So.

A

What is it like, the name already to death, but it's content, addressable.

A

Audience will see a supposed to mean and the think it's supposed to mean a little.

A

I-Car see everybody here consume. Those are things. Does anybody know of men.

A

Marketing everybody very good so yeah, so it tries to combine the two. I see core.

A

Ideas of content, addressable fire purpose, my calming the retro positive.

A

Will give right, like everybody knows here right like any, you do right, so a.

A

Trust come on to ideas of gifts and all are things that are at the core parking.

A

You can something new with a couple of different use cases well completely.

A

So yeah the long part of what I mean to the common of graphical data.

A

Synchronization tools, it's possible contree, synchronizes ok2say has medicine.

A

Of treatment, specifically, the use cases are that you might have an electric like.

A

They're like something like a 10 years arm dora. What our information that you.

A

Want to synchronize about across the model systems and an opera version right.

A

So it could be nice to a container in tree, iot 3, the anthem it doesn't even.

A

Count all the same. It's all about shipping lots of different as directory.

A

Treaties or files with them over the internet and keeping our session.

A

You get to like, for example, they can be useful for the coronation of your.

A

Home directory and can be useful for background, but victory's of the lighting.

A

So you get a couple of things that I'll talk about today, so the primary thing.

A

However, is delivery of what images and I'm pretty sure like most people, can you.

A

Probably have some use case of that in some former analysis model, and I.

A

Mentioned container system on the internet orange juice, I teach.

A

Development or something like that, I work with the ends on the things opposed.

A

To speed out there is me, thank you yes, so ca things can work up to two.

A

Different layers, first of all, accountants work on the block line. The block layer is like, with our taxes to death, sda or something like.

A

That, in that case, what it can do, for you is making it a little positive images.

A

Where I like definitely sweet image, right, xss, image or squash a detriment.

A

And that's what it will deliver for you as a binary, explicit image to the other.

A

Player can also operate on as possible. In that case it doesn't do the block.

A

Lighting it instead will operate the level of files and directories right and.

A

I wasn't worked kind of guitars, they need, but little bit dense. So through the.

A

Entire thing, like this time, you'll see, I think these two different layers are.

A

Visible right so yeah, let's talk about it, I would actually not really doing any.

A

From everything I talked about, like it's compatible it'll take until you was kind.

A

Of juice workers, you still don't have any feeling was actually going on there.

A

So yeah, let's have a discussion about what section technical background. So the.

A

First thing that system that is saying it does when you run it, it will first.

A

Utilize all things: if we operate on the block lattice easy, we can just read off.

A

The box from the block you life, like challenge.

A

If we operate the filesystem and we just realize the directory tree, the same way.

A

As target because that's exactly what target it goes through and directory.

A

Tree and generate the denotation of the second step of what th think will do for.

A

You is we'll take this huge simulation right leg. That's the idea that it's huge.

A

Lit it up, this up means it terminates a series of chunks, chunker's special word.

A

For block- and the interesting thing about this- is that these times do not.

A

Have all the same same type? Instead, they have variable size, as that is key.

A

Feature and it kind of idea that I think we came up with or pioneers in.

A

Everybody's life and that it does that what précisément do there may be good, go.

A

Stream, the entire screen and something that into a little chunks but the actual.

A

When it puts one in campari is dependent on the content of the channel, the idea.

A

Behind that is that the same data will result in the same chunk silence the.

A

Benefit is, if you have launched, there is asia.

A

And next day you see this if you're like the same and they're completely or both.

A

Of us again right and very little thing, if you think m changed like, for example,.

A

You had another file and directory at the beginning right that the chunks that.

A

Are generated from this are mostly the same, except for some local chunks around.

A

The actual change may follow me right like if he lead also purchases to always.

A

Take equally five chunks, if you do that, and you add one by to the beginning of securitization and of course all the.

A

Chance all the way to the end will change because in every single chest one.

A

White bike will be flushed out betting. It will all be move to the rest. So the.

A

Coronary is, does not music but use variable type chunks and make.

A

The chunk size dependent on the content so yeah adding any provided function to.

A

Not ripple into all the following chunks, which is to say little, the algorithm is.

A

Implemented with us, an algorithm called perhaps but hash is a hash function like.

A

Everybody here did you know what hash function in one way or another, but there.

A

Is a special one is called so called titan' hash function. It basically allows.

B

You to to very efficiently calculate the the hashes of a block of memory and then.

A

Calculate the edge of the block memory that is shifted by one by two, the right.

A

To follow so it's basically very efficient if you have a window that he.

A

Passed throughout the relation for example, and calculate from every window.

A

Every overlapping window that the stimulation has detection- yes, really.

A

Some typical that now what ta thing does are that hesitation goes through the.

A

Cessation of the sponsor algorithm basically calculates the hash function.

A

Over every single window and is the hash value that is calculated like that.

A

Matches a certain text that will put up chunk boundary right so now here that is.

A

Same data result in the same hash value and if the hash value is ostensibly junk.

A

Unless we control, if you want to same data development, a cup was different.

A

Data resulting different cup, the has actually used just for the multi carrier.

A

And complete trivial: if h, is the hash value that we calculated when we do modular calculation have q minus month and I think means.

A

That I think you we can choose what the average chunk size shall actually be.

A

Right, if you pick a few small, then the test h1 with q, equals simmons one and.

A

Will be true very very frequently, and if you can use queueing large value and in.

A

Wrote yeah it's our long. Was it too much about theoretical numbers? It's not very.

A

Hard, so I can't hopefully, we've got some things here that I was talking about, but.

A

Yeah to use the direction, I don't have to care about all that.

A

So the first two sets where theorization of everything.

A

Chunking things up the third step now is, after we got all these jumps. We.

A

Calculate a strong cash value of each of each chance has a hash function. You to.

A

Shop just evict everybody does that I presume.

A

Now this is where the ideals get now gets into play, because now we can use.

A

This strong hash function, like the has a little calculate for each template for.

A

That but identifiable chart. So at the same time as we do that we actually.

A

Write out into its so-called index file, the index file is nothing more than the.

A

List of the transaction right, so the index file will now describe our.

A

Accusation perfectly right, because you just said yeah: you first have to put the.

A

Chunk which we hash mark play with the hash value so and so then next one is.

A

The tank was the hassle is and on and on, and they go the four step.

A

Now is we take the choice that we already ate compressive individually and.

A

Stick them in come directly as regular file that are named after the hand, value.

A

And have a content to compress content of the charge right. So let's do the.

A

Trillium, like the penthouse because can actually use the sharp 206 command that.

A

You get on the shell. Likewise, on google correo tilde, consistent working on on.

A

The other side will just return you. The final answer, so an authority, everything.

A

Tha, canada, so directive 59 it has host eps. The first one is that was that.

A

Series agent, the second one- was splitting xington jump. The third one was.

A

Calculating the strong hashes of these chances in writing the healthy index.

A

Worth the force, one is taking the chunks and restoring in the in the in the.

A

Chunks, or, of course, while is my pretend that these are four separate steps. They.

A

Think them all the same time so that it's readable dancing. But this was.

A

Beauty, we didn't pretend they will do all that. One video that question is.

A

Equal to her mississippi fish manager, baby shower.

C

Penalty shot acted so, while he still missing work.

A

Yes, so the question was was now regarding is choice, a function and we.

A

Use sharpeners, if you think there and it was very wise, reportedly vulnerability.

A

And chance, and one so yeah, yes, picks up the animated camera. Typically, we think.

D

This at the points in time, right now that time, right and especially well with.

A

Me, but it doesn't really matter right like if you, if as long as he a taken a sense well, it's good like you have to go with.

A

Times and yeah they will eventually, when chart. 156 is going to be.

A

Broken there will be another version of the a thing that english r 12 or.

A

Whatever kind at that point in time, but at this point in time has 10 consecutive.

C

20 days yeah, while giving users a chunk, so the.

A

Question was there like if I lose the chance by storing it in something alex. I.

A

Lose and the answer to that is needless use- red chakra, the chakra taking is.

A

Small, an entity that is creating it again. Yes, let's talk about restoring all.

A

The later well sometimes about that, but yet about.

A

The animation, once I have shown to you, he continues to take the questions like.

A

A pendulum what chance, either specifically you on you there's no clear answer like that. Again, everything that I talked about is.

A

Not normal it anyway, right, like anything that I was talking about, has been, is.

A

Limited nonsense of the race, not discrimination, but the concepts are far.

A

From you they are 1983 or something and they're nothing different, but so there.

A

Was a prior ours and what they think default canal fix it: okay, as average.

A

Chunk size the minimum like it will not commit super small chunks, though it will.

A

Enforce a minute transplant of a course of them, and it will important maximum.

A

Chance that is four times of that right. So yes, but thank you for okay,.

A

The average, but it repented in this case you might want to actually play around.

A

With that, but we'll talk about it later right, like sometimes in one small.

A

Sometimes you would bigger ones continue up to you. One of the key features.

A

Actually doesn't give you that control. Where did you otherwise min and max look.

E

That's missing one who, compared to the average joe's so.

E

That if I choose average a title or 400 k or something, then it will always break.

C

Up a chunk larger than 400 k, even joe yep, but actually the question there.

A

Was if that is four times in the force, oh intent on the average one is a pig.

A

Chasing actually committed deputies between all three felonies, as you wish.

A

But you see is mobilized, would suggest people to do it and just like, I think.

A

The four times of the force is okay and then just pick the average one forget.

A

About the other one, but you can do what anyone I can visit the statistics of.

A

Sets are not trivial right, like um the average time side is a function of of.

A

This the module tests actually like I mean it, can pick you slightly something.

A

When there's still some kind of calculation involved to actually come to.

A

Liquid yeah, I don't want to be that technical mathematical actually talk.

A

About it anyway means questions all right, although will proceed to actually instruction, so what an extraction.

A

We simply reverse effect, so first that we acquire the next time a makes final.

A

You remember with just this list of strong hand, values when we have that we.

A

Acquire each charm, but downloading from that work or what we have in that chunk.

A

Store directly and uncompress it and just concatenate it again so yeah, but.

A

Dessert, the concatenate, the occupied chunks and there we are, we have our.

A

Original translation and then the 4/7 used to rely that theorization by the.

A

Disk again, either by by facilitation of the file system, describes like pd, was.

A

Right into the what device or to some new text file, whatever you choose or in.

A

The competency level, it will just be done on tart. Well, that's kind of.

A

Already everything that's due today, it's very very basic right. I think I can't.

A

Hope that looks if you've got what this does right and doesn't really get any.

A

More complex than that, this is the entire like computer science.

A

Fits with our behind this yeah, so let's talk a little very briefly about so what.

A

Does they think actually two different compartments? The main I didn't have many.

A

Differences and visit no as attention to see is anyway comprehensive. This is just.

A

The one key different that I think is coming is the most relevant and that's.

A

The final boundary, because I mean that's what our scene is about about so.

A

When harding does right, everybody who uses regularly right, it's a you specify.

A

Some remote concrete and one local file tree and then what our thing does it go.

A

Through this file trees and looks at the end times of files, you want to find two.

A

Five, the same name on both of these sites. If the end times.

A

Differ on the arcing algorithm actually interesting. This an arcing actually gets.

A

Activated, that is, it starts doing the chunking algorithm doing hash function.

A

Because our thing is pretty oath, that hash mark is not chopped 2 /, 6, +, 5.

A

Originally updated of them, but so if you say to be.

A

Same address, but it is primary and originally always about the file longer.

A

To them right is to five films. They are the same name. We also are seeing.

A

Algorithms, won't actually do anything for you right if the if the two files.

A

That don't bear the same name. Our thing is no better than acting serious for.

A

Example or some other two leaders right so they're actually interest any most.

A

People who use our can from the evidence never actually realized that this smart.

A

Bit about our think only is what is buying 2010 names with cyber defense.

A

Company, so the key difference you took from arcing to see a changes then see. I.

A

Think we read a cat about a 1005, we first see realized and then we split up.

A

We don't understand the file of the first and only set up off the responses.

A

In the file and that's the major difference because of bdd means, we love.

A

In our chunks, some small class together right and small files are everything.

A

Right like if you, if you, if you look at a linux directory tree in sd for exam.

A

You have a shitload, very small files at the house at the hostname. All these.

A

Happening they have like, I don't know some of them.

A

Is 10 bytes or 1100 right, but it's still very, very small has no way abdul is.

A

Every cheese chocolate with caa that's really nicely handle because all of them.

A

Are clumped together until we average tank size in the tech toad, and you can.

A

Get up also the reverse of the price to large files. A nicely split out bites is.

A

He a single individual chance, so what jason gives you as much.

A

Guarantee is that the chances it spits out really has the average campsite.

A

Regardless, how small, or how big individual files where they get you put.

A

Into music right, so yes, they are teaming size and another spec is really.

A

Worthless see anything because it doesn't care about the I'll boundaries.

A

Is actually really good at finding similar areas in infants and that.

A

Basically means that if you move and file in there actually trees, if you just.

A

Rename it if you, if you copy it ca ca, will recognize that, because it doesn't.

A

Really care about final aims, because it doesn't really require two.

A

Files on those sides to have the same name and then doing the entire thing and.

A

So on, because it will just recognize the same data regardless, where it is in that spirit, damien, and it is around ten types.

A

Of sterilization orbit at that place or that place it doesn't matter, it will.

A

Always we know the same chunk and yes, so that's the main difference for our space.

A

I'm not saying by the way that our thing is, that is absolutely not. It is this.

A

Seven computer science, especially since nobody else did that before and by the.

A

Tens ages in use case it's for synchronizing, directly treated like.

A

Individual see, I think that we do that, see the figures. We use cases that you.

A

Have lots of very similar trees that you update a lot of frequently and you have.

A

A lot of clients that exponent down now: why do we do all this? The reader.

A

Detector that it gives a lot of very symmetries to chunks will be mostly the.

A

Same that I've generated right. You have this transfer positive at the tran store.

A

Where you add a couple of chunks, when you only add the chunks that haven't.

A

Been used before that they can be mean if you have your container tree and to.

A

Keep working on it right and today and have that version.

A

And then you know the bucket and tomorrow you fix that bug and want to.

A

Employ that again, the directory tree will be mostly the same right change. One.

A

Binary, effectively or or or one text file, whatever you change, but pretty much.

A

Everything outputs say the same, and it has automatically to the effect that the.

A

Container trees will reside in the same chunks, except for a few chunks. Actually around this doesn't exist. So it's a it's a very.

A

Efficient storage for storing lots of very similar work relatively similar and.

A

There trees, like you, have if you do.

A

Frequently up in containers that you do fabrigazi updating or you cannot.

A

Complicity to any kind of updated container, please iot three, the entries, whatever you call it right, so that this kind of key like.

A

Tht to something you shouldn't be using, if you only have one copy of everything.

A

Because doesn't matter it's really about something where you want want to learn.

A

Many repetitive similar things, another really important concept was, they think.

A

Everything to you think is like the reproducible and process. That means cac.

A

Can't be used to deliver like many phonetic data, because every single child.

A

Is protected by the strong hash and the value and the image file describes the.

A

Entire simulation, when you access it, when we extract it, you get the guarantee.

A

You get exactly the same two relations before this is not like we're kind of.

B

Talk, it's very heated like at the end table.

A

All and you go to like you, can edit a business written if you like, and change.

A

It by that it will not be recognized right. So as long as the gimmicks are.

A

Protected the entire simulation protected, that's something that is.

F

Similar to get married easily, of course, is kind of a fear. This is a poster.

A

Particular system, if that's what you want, there's no like in today's world, we.

A

Live in a world where, where we know that the nsa and russians or whoever else.

A

Hack systems all the time, so I think it's the absolute duty that anything.

A

That it's down on all the alleges all enhance images. All the container images.

A

Are 30 days on download and they didn't even on like that so yeah. I think it's.

A

There's a core tenant: we do it that very question, so this stuff is.

A

Designed to be used with http or something them up like so the question.

A

Was how to actually translate the in the class? The idea is that everything is.

A

Http, like every nook, the world of http, this table is designed to be very.

A

Friendly to http and the way people use it in the day, meetings and comedy.

A

Networks so I mean this kind of respectively, of the average chunk size.

A

Stuff, because it's really highly cashable and you can make the best of.

A

The city and because you don't get a huge file of your os treatments, that.

A

Every day you lump on the cdn and nobody can cache so yeah, but the idea is an.

A

Image file is, if you gather to some second channel drink and get some.

A

Suating, if you have any doing dvd verification- oh right, but there he is.

A

Basically, as soon as your unit, everything else is stable right now, c88.

A

Doesn't do the verification for you right, like it expects that you somehow.

A

Applies with me and I goes like a store entirety so well, but it assumes that.

A

They that the image file is trusted away, but I want to take that actually so that.

A

See a thing can actually book dvd for you and, although you downloaded and the.

A

Detached signatures, those because I mean that's how you have to be quiet.

A

Otherwise, it's pointless right. This way is the index files and not trusted than.

A

The rest for the paltry, if you have an itch all you get, is a very good present.

A

Content but as national palace, a garbage collection happen and the answer to that.

A

It doesn't at the moment, but I'm working on it, but the idea is like I mean it.

A

Making you specify you help you think about a couple of these. The next time.

A

That you actually still care about and then we're.

A

To remove everything almost all of the don't, it doesn't didn't, show the showing.

A

Up and even excel right, but it's a powerful antidote yeah, not very funny.

A

Dude, yet he has very thing, for those who know is like this thing that it's something that chrome, os and relatives like it.

A

Like an instance where, basically, every single disk accesses cryptographically.

A

Verified at access time, which is excellent because it basically means.

A

That offline changes on a portable review a bit earlier to it and the other.

A

Systems that are loaded like this, like a western, for example, 8/10 multi context.

A

Again says they will do verifications and I'm going to download the non after.

A

See I think you can use those modes actually see. I think and download.

A

Something for you from that point on is on you in the specific module, which is manipulated your problems, and you can also use it in a mobile able this crowd.

A

A little later, we basically say yeah very, very blocking against we block as.

A

It's needed and verify, but yeah it's not about a little bit later. I already.

A

Mention that it is making intended it's like, you choose the other two oxides and.

A

By making a large you anything in prices that you need by the collective object.

A

Of every grammar correctly, and so by treating the average and what their time.

A

Size, you have the freedom to say yeah. I want many requests loyal. Few requests.

A

Like the trade-off between how much you want to pay the cdn provider and how.

A

Much you actually want, like I mean a lot of times, gets the less kind of reused on.

A

The client side right, so, if you do that kind of stuff, it gives you a little.

A

Control how much money you want to spend and how much they do possible itself.

A

That so why all this part to were just a really important content area when.

A

Acquiring new version of some directly example, we can use if we already have an.

A

Old version of some form that has a chunk source like sc. The way is that.

A

Some is beta, give me a sign, saying re right. So, let's, let's say an example. You.

A

Have a container image and you can close up the server and the next thing to play.

A

The next version of the server what the download was they think they can do for.

A

You it it can index the first one. The same way like go to go through.

A

Determination generated chunks as the hazards occur, for you.

A

And then, on this second day, when you update the try to update the thing and.

A

Roll down on the index way, I look at it figure out. Oh that check. I already had.

A

From yesterday, in that chunk, I already have one yesterday, let's just copy that.

A

Over from tomball, I already have that's only down the few chunks. That's actually.

A

Changed right and that's key- and it's not only useful part daily- contain this.

A

Is updating flexibility much anything because you always do have an old version if you're doing out there, so you should be able to make use of whatever.

A

You have, and the good thing is that all this happens fully automatically right.

A

You do not have to to do called-- anything. It will just find the filament.

A

Similarities completely automatically for you, if you have an iot device.

A

Usually you have this ad setup when you have one submission area in one position,.

A

B and then a petitionary, you have the operating system in economy, improvement and petition p. Yes, the one that you put the battery that is going to update to.

A

Next right, so then, you always have two versions of the operating system. That is.

A

That entirely clean space and yeah one is always one to run and the other one.

A

Is the one you going to run next so with the a things but not just natural? This.

A

Design, because the basic you say is I'm booted from from position a then I'm.

A

Using submission, afc and writing to petition me as I reboot to participate.

A

As if acted that want to get usb as a seat and write to a again and so on and.

A

So, on and off for requests that you said earlier that you have when.

D

You run the over on someone, they exist in class, but that you have to build up.

D

The storage the lending is to copy from that in gds violently. Well I mean them.

A

The wireless healing works is I go through everything and then just.

A

Remember I was also you can, when you're applying together this. You can hope the.

D

Other people, preference, yes, it's a vetting is heating. It really like it.

A

Really yeah, I think my aunt implies a question. Actually the page and the.

D

Present series we about montana copy anything round unless my connection is.

A

So sitting also work with a treat I mean here, get angry yes,.

E

Claiming that let my opponents promise we know yet it census.

B

Well, I think the question was regarding it is that much more difficult if we.

A

Actually, do that not the blog layout in the files of the mayor, because in that.

A

Case we have, we can't just jump to month with exhibition. The physics position is.

A

A past club and offset plus actually a couple of more fives, it might come after.

A

Is where the chunks will go go well, then, is all in there's hope for you and it.

C

Works really nice trees changes. Well, that's fine, because I, the question was.

A

What happens in department decision tree changes while the seeding takes place.

A

And why we'd like between the time of the see, happens and.

A

The thing is, and if we go through it and calculate the hashes of these chunks and.

A

Remember them and remember where we got boston and then later actually means.

A

Because they are referenced in the new version and we will read the block, will.

A

Verify it again because yet we have the hash, so we check it if we notice.

A

Actually not matching row the way down of the chunk anyway right, so it's.

A

Completely robots against that when and it's an assessment actually an excellent.

A

Segment I like, because you can throw any kind of at it and it will do the.

A

Right thing I already have two port and one yes, okay, so the first one is.

A

Regarding a what happens, is the I gamma today with, and everything was put.

A

Together for specific chunk size on the next day for different chunk size, so.

A

When a new index files down under this is supposed to be applied, the index file.

A

Contains metadata is not actually just a few words list of hashes.

A

It also contains information about the device concert right, so it was out of.

B

The index file will then start feeding and then will actually make use of that.

A

So you can change it that as you like, of course, if you have the central junk.

A

Store and you keep changing the average type size and you can't reuse any chance.

A

That's up to you, you need to know that, of course,.

A

Yes, but a single tear is painful, but the text or might not be if you keep.

F

Changing every question the test, yet one of the thing it has also not realizable.

F

To avoid the manila or education system in the future.

A

Well, so the question was regarding whether tests like modern tests, they can.

A

Be changed while you imperfectly change, but it is for me to break right. I can.

A

Even say it's designed so that we can make incremental changes in the format.

A

Sooner or later, but that would be one if we actually change the test.

A

Yeah but I mean you know, the text would look like it. Everybody know the test.

A

Like the same way since 1983, I don't see anything changing in that area. The hash.

A

Function, they will, I, like you to be locked out.

A

Eventually and other things, but other things text matters because for it, but.

D

Ideas a mathematician, so what do I any other questions.

G

Dana well arcing differences same there. What it is it ain't until our sickness.

A

So are things eunice language of algorithms, like tiny xxx toxins like thing came out and by the way is alive in 83 you think 92, and but this is to.

A

Have changed to them so they do not use potash. They use something called aha 32.

A

Which is something that came out of teeth development, which is also money.

A

Actually and besides the fact that and the.

A

Results are not. Cryptographic was much more like cryptographic, hash, hash, hash.

A

Mark and another 32 is the text. Ultimately, is all the thing.

A

Well, in some people like getting that balances.

A

A little rustic, for example, they don't you moto chesley. They do a tech where.

A

They they only to make chunks of articles of exponent of 2 and then.

A

Instead of doing the model check, they do some binary thing, but it's kind of same.

A

Thing, except that I accept any kind of what does better so yes, please, try you.

H

Think are unique either movie, so the pressure of where wonder what the.

A

Limiting factor is or uninteresting by the speeded then maybe depends like that.

A

We can't be used like a compression like within a single natively compress with.

A

Access and access, slow and that's kind of a main thing right now. I like this.

A

You, if you actually create a disk image with it, but if you chuck it out from.

A

Craziness and lola, these none of anything is like that, and it's probably.

A

Wanted to take the old, replace by something faster like we're gonna play with facebook, progress which I, before up the name of something come up with or.

A

Something yeah, it has a very nice name. Just call you come standard makes it is.

A

Calling th enemy always notice that everybody should do better, but I don't.

A

Know it's like tell that kind of is limiting things. If you download see a.

A

Thing is really really easily. Can I completely fill up your your real.

A

Network link, because what downloading firstly in exile, but as it has that then.

A

It can go on and download the chunks own peril right like to just know them and.

A

Then basically means electrics a thing to deal with that stuff, because if you.

A

Build 90 divided, probably not a good idea to do get requests all the same time and plumbing of the network actually has.

A

Support for specified bandwidth limits, electrons take more because in one town in the background month, not the crime machine. Well, let me finish my flow.

A

Regarding few food, yes, it's ok, one more really important thing is to come. The.

A

Difference from this to travel, business, there's no remission, control register.

A

Right, meaning what I mean by that the thc will recognize similar data.

A

Automatically for you right, there is no requirement to ever tell cfc. This is the.

A

Ovary- and this is a new version and version numbers anything like that, and.

A

We'll just figure out everything automatically: it can reuse, something we use it if it can't cost. This is excellent because you know the.

A

Debian and developer example a very simple assistance. We see a cd connection.

A

To cross up it, they can use a debian image as a seat, and there is the north.

A

Edge of it as well, of course, be much less than 10. We use much less because.

A

Composite if encompassing ahead, but it will still be able to reuse a lot daily.

A

For sometimes of data, each block that selection kind of payment on all system.

A

So, yes, and even though fedora zillion don't have a common history in any way.

A

Like the distribution that he put together with weather tools, do not have.

A

A common history, so you think this tab will take whatever cancer. So one more.

A

Key difference- and I really want to put one like the anthem- is on it. The key.

A

Term is revision control? I don't think the rhenish control should ever be part.

A

Of the machinery and don't refer some kind of employed like because the doctor.

A

Had this thing would have toggled and they have a delta table, while the delta.

A

Now, power to actually deploy returns on some system, there is a need to download.

A

A double and because people hate this and they flatten things and then they.

A

Kind of talk about a goes out of the window, but the key difference. You've.

A

Read is, there is no reversible shows because revision control has no place on.

A

The deployed device revision control of the tool for the developer and not for.

A

Deployment so ya, see a cig. Won't do that for you. It will find things.

A

Automatically and doesn't really care about any kind of historical.

A

Relationship between enemy yeah, I mean it's kind of nice like break out a.

A

Docker, like the way how people build their images, is they always start off.

A

From the same image, rather, they always take that you would live into the.

A

Official one and then make the changes from that and that's the only way how.

A

Does god was actually to stay as small, but in this case it doesn't matter? You.

A

Can actually take apps captain when death looks at whatever in building your.

A

Image every day completely from you and is entirely tiny to do that because they.

A

Simple automatically recognized, for that is that there will not be a difference.

A

Yes, any presence to the part of the light yep. I already mention that and.

A

That what does he does? The theory nation of the directors republic are very early.

B

In a car buzz and just a long lifetime, not hard, that's for two reasons.

A

Like I actually like, it actually uses hiring particles asian.

A

Part of cac commuting penalty of the recipe is being like without detecting.

A

Without detaching an end form where you can just say, give me this irritation of.

A

The director in g- and we call it dope- he ate our files entire file, because it's.

A

All our planning, experimental ca and yeah- it's really like at our mother, has.

A

Some greenery properties that are double offer and you didn't reason why I do not.

A

Use targeted the for me personally most interesting when I slip reproducibility.

A

With see a car by the definition of the former there's a guarantee that one.

A

Dietary tree can only have one a specific bite, exact series, ation, there's.

A

Only one, rather than one of them that maybe means that it has a variation, is calculate the hash function as I'd like we have any absolute. If the guarantee.

A

That the resulting directly matches what you think it matters.

A

This isn't from time right the entire, because there's the entries can appear.

A

Basic in any order- and nobody has bothered to specify anything there and.

A

Because the the reformer that has so many variables, basically there are any.

A

Number of valid two invasions of the planet- endor activity, some of the.

A

Implementations of tar try to fix that, but so that they give you the guarantee.

A

That, if you use that tool to generate our goal of that directory tree, then it.

A

Will always be only one and one only, but this is that, in that case, a property of.

A

The implementation on a property of the of the healthy commenter.

A

Nc a time and that nearly is everything's are strictly reducible and.

A

As one limit under this another major change from kyoto target right magnus.

A

Meaning, if you want to jump to a specific parts and directory.

A

The relation and you can do that then then, parallel pen time, you can do it in.

A

O log n time multiplied by the decibel directly ns. Let's let major difference.

A

Right like because, as your file directories grow, the only way how you.

A

Can jump to the 1 million file in a tar? Ball is by iterating through the front.

A

Nine hundred thousand nine and nineteen time and so on, file. First right, that's.

A

Decision different performance, so yes, these two things are the main.

A

Differences they have about how to write an actor exactly excellent, because.

A

Waiting an alder to do fuse and you can just australia, because and if we can.

A

Jump in in an excellent time to any file in the situation we can do use. We can.

A

Expose like an archive of it as a few times as we can not develop it, and in.

A

The background we can download by http, whatever you like with chunks and you.

A

Access them, but we can tell you, have to download the chunk that actually are.

A

Needed for that specific part, so yes a little bit more about how to see start.

A

Stealing so we have files that a directory with one of these four topics.

A

The c8 idx is a an x file or directory tree. Cai v8 is all the linux file, but in.

A

The paper buckets right like the difference between on the positive 11 or.

A

The block leg c8r- I already mentioned this- just a little lighting- is better.

A

Targeting right, like the series actions of our country and don't see a sdr.

A

Is the big chuck story and the directories appear like the director that had several topics? This is really small. You need to know about this stuff.

A

That the see a single to spit out, writing like if you can actually check.

A

Out the directory tree, what it will spit out will use one pai x file and then.

A

Drop charms and one c ast directory. If you do the same for block.

A

Device it will instead generate once he regulates and also drop 7080. Okay,.

A

Something is also I really care about it. Metadata control metadata is all the.

A

Little bits and pieces that you need to know about file directory metadata for.

A

Example, some ownership like which uses on this part there's things like enzymes.

A

Modification time it seems like apl, extended attribute and as linux guru, who.

A

Gained more and more and more and more business metadata nstac, we try really.

A

Hard to cover them all, but that comes in theory with drawbacks because like for.

A

Example, see a single to say, restore for you, this big, that they, the chakra the.

A

Change occurred. Part of the matter is not sure if you know that they are not.

A

That well-known, it's like an additional bits field for every file, the most.

A

Important that you can set their most well-known is one that's called immutable, any seminal. Any kind of texture change the file anymore. Now the.

A

Hr will tear let's utilize, that for you, the goal is, I want with the disability.

A

Right I want that one directory tree in all its position. It can be sterilized.

A

And we recently get an exact same everything back. Do you think? Oh there's.

A

A lot of details to do it all these little bits that actually tries to.

A

Civilize them what I try, but kind of drawback right, because, depending on a.

A

Use case you actually want different amounts metadata few lines, for example,.

A

And all of what I was just talking about another use case for you: can those.

A

Backing up my home directory every day, in that case, I just really.

A

Care about which use id which demand use. I do that's come directly because if I.

A

Want to back it up and restore them some different machine, and on this one I have.

A

Using one the other one I have 1001, it doesn't.

A

Really matter, I think the fact that the number is different.

A

Doesn't change the fact? That's my popularity. On the other hand, if you.

A

Actually employ a a container image. The metadata is, you want a lot more native.

A

Methylating actually care about the user idea of who owns it, because that's how.

A

Unique access control actually works. On the other hand, you don't care about the.

A

Modification time in that case, because my education time got awful but education times basically means that is to compile the same file twice the same.

A

C file twice on this same day and the exact same fire him additive result of.

A

The same yellow fire, it will feel the difference because one got done early on.

A

The other later because two different attacks, but generally people who.

A

Actually, care about deployment and positive trees want to turn off the.

A

Stories on end time and the fbi thing kids, with full control of that it has.

A

These happy it has these touches that, like latex, for the reason remove the.

A

Double such as that suppose, we'd ss, with investors without absolute good novel, a.

A

Take a parameter controller, but what about this time? The question was about.

A

Exercise so exercise something the calibration resort of unix. There are.

A

Limits the only thing that it can change a lennox is the empanadas c time of the.

A

Active time the best to deny the awkward unless you go through the public level.

A

And I'm do some widget and hence island board as any. I don't even support c time.

A

Meal, I have a very good reason, but I forgot it. I've made another time I'll.

A

Tell you remember so, but there are many times the ones that match the.

A

Avant-Garde and again, enzyme also does not matter.

A

Okay, one question that is pretty interesting is like a bee. I see.

A

Frequently, you ship your your discriminative torture test now squash.

A

Japan and for those who don't know the file system might decrease, but it's.

A

Compressed and as we only in a best way, I can just think what you want it and.

A

Distribute them very efficiently and if you want to have them, use very little.

A

Space on your ema to divide now, swastikas images are compressed right.

A

Compression is, in theory, a problem with the estate right, because compression is.

A

Compression works correctly, like the, for example, if you would actually use it compressed. Our bullets think that entity a thing which is totally cannibal to.

A

Accept that, like maybe get together already serialize thing, then, if, on the.

A

Next day you generate the same tarball, but with one bite change somewhere due.

A

To the compression, which is one big change that you might have done, will.

A

Explode into the entire rest of the of the of the compress screen, because.

A

That's how compression works right? They tries to reduce the remove redundancy.

A

And amazingly, as effect yes, she could change one vital exposure to the rest of.

A

These of the compression station now so yeah, if you, if you use a compressed a.

A

Ball and put that as a pretend block device image into see a think will.

A

Happily do everything, but it's not going to be able to recognize much data.

A

Because yeah and it will up to that point way to change but from that point.

A

On when americans enemy now as for success,.

A

Is all the compressed upon will as humans all the great? But it's not.

A

Because kwacha says because it's random access, they need to be able to to locate.

A

The data that they need and access it's not a time to compressed what it does is.

A

It's 1,000 new blocks and these locks are individually compressed, but finding.

A

These blocks is not compressing, basically visit visited if the.

A

Concatenation of individualized blocks, but the compression always start again.

A

In arson, block size has reached right so, and that fact is actually good for ca.

A

Think because it has the effect that changing one-sided somewhere, the prompt.

A

Does not ripple through the entire image, be the block at the end will still be.

A

The same right, so you connecting your authorized and creating the combination.

A

And will still do good, not as good as an uncompressed file. They will do but still.

A

Be ok, of course, and you need to somehow sync.

A

Up the block, silence, process use the unit explorer type and the various.

A

Websites that see a success, and you have to sing for not, as man delight, that I do.

A

Not understand yet, but there's some research showing lots of people watch.

A

Figure out what the best way is, because a my assumption is that this quadrant.

A

Has blocked they need to be pathetic, smaller than and creating websites proceeding to do best. There's a give up issue. If you want hollow the thief discussion, some people are our happiness for me. Rhythms.

A

Abilities everything so really. I was like. I want that the entire trees can.

A

Always been reproduce and that's why you can actually taste it has a couple of.

A

Different words that you can use wanna make one of these in exile and.

A

Source up an installment to expect it. But as all the see a thing dive into.

D

Using em tree, if you think I didn't calculate the sun, I mean as an angel.

A

Calculator diapers over a director chief and what it does there is one to.

A

Serialize, it's not action characterization for calculate this assassin of this derivation by the duster, so it's kind of like you know how.

A

People michonne 2056 done on the command line to calculate exit of some file like.

A

The content of file we're seeing guidance. You can do the same thing. Other.

A

Well, entirely directory tree will give you one hash tag and describing exactly.

A

The record tree in all this metadata and everything the metadata again, you have.

A

Control, you can use that thing with with who, with the desert, without.

A

Individually, select the metadata bits that you actually wanna store them and.

A

Creating actually is kind of similar to that's entering something. There's a cfd.

A

Concept with the previously people can upload that it fits in many tests tree.

A

The basic text- format where you can it just lists stupidly.

A

Metadata about past directories recursively retrieve like in certainly.

A

Content metadata about them, I can show you how now, let's make sure to do that.

A

So let's come to the demo section entities we met. So if you invoke see a.

A

Sink, which is how to get this long health what's interesting here, like it.

A

Will list all the busy at the end, at least with a whisk and then the file.

A

System properties, but you can either choose to include in their archival or.

A

Or the digest, aeration or knotting to but yeah, let's just invoke it with once.

A

A month I said see, I think I just, and I hope that we're confident divers of my.

A

Contractor trade- that's let's see here and that precisely is quite anything. The.

A

World in the file, in that record, you might break down with me now touch.

A

Some thing yet because the directory build itself, it was a diverse, will change, but it'll cause again goes well to write for the blog and entries has.

A

Some other data, giro country- let's dissolve this stuff and show you.

A

That's neither use smoke, make up some smaller and that's really is not a.

G

Former, that's what I came up with this stone from vsp, because yes- and if this.

A

We just described here's a file by that name and the file women has this mode.

A

And exercise and you they'd be in crew baby and you, the main group name, is time.

A

And the project is excited, but yeah. This is just a side feature. Actually, let's.

A

Actually use the async to create our purposes like this from this directory.

A

Tree my development three seven years, not an ice cream, yeah pop video. It's not.

A

A westar in this case just like norman treatment, the identities of academy, has.

B

In there first, so if we actually want to do a an index file, we'll just do getting.

A

Make give it a name and run that and I'll take a lot of their context. Part of.

A

That is actually kind of march and take them all what you're waiting for you is.

A

Extent and then you go will also spit out. Jesus said, I tell you what, if I'm.

B

Generated position x, file florence's people were not meeting it. 6226 k inside.

A

Rather, we're going to kind of buy me nonsense. I think it's visible and next to it and actually put populated this very false.

A

Var hdr with it are chunks, or we actually look through that look like.

A

This they're always in individual files, they're named after hash salt xp and if.

A

You actually use on ip to fc. I think, for example, and then do this right. So I will.

A

Now uncompress this file and calculate all the.

A

Of the compressed file and we see charlton and then we will actually see.

A

That this matches right so this well, it is calculated- and this are the final and.

A

Exactly the same, so it's kind of nice that I like this, this concept here that.

A

There is no metadata now nothing, it's like you can actually go with your shelters and introspective story will actually be able to validate anything.

A

And do all this myself now we actually want to come extract that there are. We.

A

You see, I think again now in extract. We set about a path to toolbar, both the x.

A

And let's say we want to be competitive, some directory here we call it dating.

A

Copy and that's what I do so yeah so one of the problems, because it's a critical.

A

Metadata some of the metadata cannot be I'm expected with without privileges.

A

Live and thing is not specifically finding, but let's make the image again.

A

But this time we take ocean, we pick a.

A

Different set of metadata, what I added here is this with our privilege, so I'll.

A

Say and so everything that you can but leave how's everything that is.

A

Privileged and everything that privileges, supposedly all the metadata.

A

That cannot be replayed again without actually having privileges like for.

A

Example, that's file on the ship right file. Ownership can only change the route.

A

As everybody knows, and hence that I does exclude that now, but I will still.

A

Include everything else like education time, whatever you like your fault.

E

Store to to not the dimension was window. This you've been doraemon calculate so.

A

The store is just, let me put the stuff and union see ya. He's sorry.

E

Now another like and the see, isn't the edge of satisfied like, for example, if we.

A

Already have a version of all this we can set aside like movie, but we calm it.

E

Down but let's do stuff, I guess it's going to use the same score right, yeah.

A

Well, wouldn't see that my something to get there, you can say definitely yes, so the contents of the files are already in that chunk right, but the metadata.

A

Isn't so any chunks? Because the metadata change? Because I suppress some deputy.

A

Now, because I've kicked out everything that is privileged, so the child that.

A

Contain any kind of man that are going to be recalculated, but the chunks that.

A

Are just putative creep you file contents playing over use. I think I can.

A

I think I just have to set by that, so those my launchers, what vector doing.

A

And it will get reused join. Tell me to put that. Could it could be right and.

A

Basically, all the remaining ones, so I fix 5 to minus 433- is a the chancellor.

A

Economics, are you sure the size of the index file today.

H

And you see the directory was everything tony to make about game site right and.

A

The the in exile is 28k and then the store both runs. Now I mean this so.

A

Cannot contain the tentacles of the ranchers will be a little bit larger.

A

Lin and the uncompressed version rain. It's important okay, because I press.

A

Cancel megabyte communist or anyway, that's now now we send the other version.

A

Now that's actually extract to bar this time properly and then marty p call it.

A

Like this now we go when I accept everything.

A

Wow, you should leave it on its fidelity.

A

So, let's good work, okay anyway, so this kind of idea of it lets them to look.

A

Like post again, oh yeah, something of ourselves.

A

Expressions they're currently offered to do this, so the question was: we got it.

A

Can you pick these the metadata options that you want during extraction as well.

A

So let the series asian contains more information than these than which one's.

A

Actually checked and the answer to that is kind, it's not supported, but it's just.

A

Because of what's amazing, but they get something that's possible, it has some.

A

Drawbacks, however, because I mean I'm all about recruiters abilities and if you.

A

Pack up a lot of metadata and then don't you play it and put take it up again.

A

That it will necessarily not match anymore but like, for example, our our.

A

Entire test cave is really about just them. Ripping things up, I'm compressing.

A

Them against the thing that I was always making sure that the texans match before.

F

Oh yeah, so basically we check everything after and that the average stock size.

A

That's the one, that's basically matters for pattern, recognition because.

A

Basically, it is anything that's more than the smallest chunk size, we'll never.

A

Be able to recognize in the crossfire, but it's not the one that actually is.

A

Directly relevant to the tem, that's actually pitfall that you have a bit is.

A

Important like, if you take the average chunk size, it does not translate to the.

A

Actual object size directly, you still have to to incorporate the average.

A

Compression ratio than your tax status will be able to do with.

H

Your compressed air does it do something. This time wait home well as well as a.

A

Credible said you never do something special to profile the whole, so won't do.

A

With anything particular when contacting them blast on when decompressing them.

A

It's sexy, smart and well. Whenever it comes across a long series of irritable.

A

Generate an adult, so it has no, no, you know it mostly relies well. Health are.

A

The way arms, but it will automatically always.

A

Make holes where it can to make things efficient as well. This player is.

A

Connection also because it's a very good one that, like you, can remember things.

A

Like that, but I know that some people actually might want to have the ability.

A

That they actually can serialize child exactly good behold, but they have math.

A

Can become amazon the tumulus, but it was a question mark on the to-do list here.

A

Like I'd ever want to do sex me, you saw that.

A

I mean when we also don't do having so that stuff, like this isn't question, but.

H

Yeah, I was thinking whatever I said. I guess this one since you just sure.

A

Content compressed, it means on a beach lots of small times. Yeah I mean it's.

A

Like at the depression was whether it makes finally likely everything, because.

A

We do compress that eighty something very well compressible and yeah huge.

A

File is very well compressible, then this will fill mena and get lost.

A

Women's of exertion, then you have a question, could fill me with renovate.

A

Okay, so let's talk a little bit of what what else I can do for you.

A

One thing: that's pretty term: he uses seating functionality right so where you basically specify, therefore, exactly like we, let's say we do it on the pants of.

A

Survival- and you have one quest reit already placed and.

A

Now you download the new version and you spent for the emergency. Then I'm system.

A

It correctly takes benefit of that and, if you desire so instead of copying the.

A

File, each time actually create oddly right. That of course comes with pitfall.

A

If these alleged trees are manipulated, of course, the changes will propagate to.

A

The other one, so we probably don't want to do that unless you really know what.

A

You're doing, but it is something that has to go, and so I saw people in it and.

A

I think it's useful if you have read any trees right, because when you have kind.

A

Of a lot of freedom, trees and everything's just around one. But if you.

A

Could not have read only tree and see a support you in any boats having.

A

Redundant so then, how can you make changes to what I think is way better.

A

Than dragons of resonance resonance for those who don't know, wrapping or.

A

Something that a couple of more modern positive support them. It's like butter.

A

Has does oracle hands? Does new versions of xss do xe for dozens? Rustlings are.

A

Something where you basically can say I can make copy of a file and let's free.

A

Because the new copy will actually still point in the old version, except when.

A

Somebody action medically one of those two side: the net copyright takes place.

A

And this is the files are ready to depart right. Retinas are much lighter.

A

Than harding's because they are transparent in their vacation, there is.

A

No propagation between, if you use that to your unit vetri, they hope they like.

A

The movie copies out, while writing so there's occasions, they will not notice.

A

That that any kind of magic going on the chad block for me, it all, doesn't make.

A

That available hard links that are actually honored on the part of the.

A

Metal like below the file boundary, so what we can actually do is.

A

Maintain that link between two files, but only have part shares, fell apart, not.

A

Right because a test out how things are usually plays, video means change.

A

Individual building, one d8r is their typical title there now, with the lower.

A

Side, another question was regarding a quiz. I become francis chr. If you also.

A

Get directly can be earning and ref links. If you specify speed, many will try.

A

To link everything up on the seat, it's not smart enough right now to do the.

A

Rest linking from the extraction is currently operating on, but that's mostly.

A

Because I've been for the hooking that up, because it was a tiny bit more.

A

Complex, if you actually need to use a source, what you can't be extract instead,.

A

Of just with over going best plain and simply make. But if any of my things like.

A

You saw little attention on that. Yeah wrappings are incredible because they.

A

Are transparent is take you like fidelity do at the end manager, right and.

A

The and managers usually work with this, given like rama skin visit, like you like.

A

Something which bt inside of them, xp, for whatever in terms of you, can use yes and.

A

Realize me, too, to download new versions of beasley and disk images. They tell see.

A

I think each time and then you shall feed with the old version and then.

A

Really only the actual changes are are placing new file actually have the.

A

Wrestling right and is automatically so they can execute other, like you, yeah.

A

Like they can be demonized, and on this, you just pay for the actual changes as.

A

Important to change of the maze and never for how many different versions of.

A

Key changes, everything and so the questions regarding and with they exist.

A

Mutagenic himself so right now I mean the indica tiny right, like you need to.

A

Call that m- and I'm pretty sure that is he with you- are kind of terabytes of data. We see a single unit, I will grow. I mean simple math calculation that yeah.

A

You know the other small sides and you know um how logical shot on this and.

A

They can multiply, help lies the following and there are some systems which I know which people with spend too much time on their computers, implemented.

A

Whether they take the image file and use them, consider that the theorization of.

A

The next level, and then the index file of it is it, was.

A

Of civilization, and do that as long until they only get one hash back for.

A

What I mean right- and I thought about doing the same thing, because hazards.

A

Like computer science, be all the cool, I can't just do this all on high levels.

A

And pills just one, and I said that that's ridiculous invested and that I.

A

Don't think it's really necessary, so we can.

A

Come father they may call there's a large. Maybe we do something about that.

A

Until then, like it's, like an exception, you know we need to get one level deeper.

A

Should we can do that, but also we cannot and an identity with point in it, but I.

A

Do have some statistics for the computer science point of view that this is a.

A

Sexy right, but also I try to exercise a little topper and simple talk, works.

A

Because I mean, if you don't do that stuff, I can tell you that in like five.

A

Minutes on my slide, if I start doing with that, and we do it on the same level.

B

Again and again and again very easily coming the space age is able to do.

A

Everything locally, obviously, but it can also acquire chunks and indexes by happy.

A

The agencies ssst ssst, like I am watching please like like.

A

Second links to curl, and so in theory could do anything that lets carl can do.

A

Though ikely yeah, I mean you see, we couldn't even get your data from what.

A

They call all the ways public health regiments curls report and what was what.

A

They call there's a copper it couldn't offer, but of course, that I did not.

A

Innate that part and but sure and yes, and how it kind of nice thing is when I.

A

Replay this connection make some changes or when it lifts things up again as well.

A

It can be you, it get ships with south to useless.

A

What is updating is add or subtract a fixed value from henry unity and goobidy.

A

Inner equity- that's unuseful for contains that you.

A

Sitting and kite, but they also use it unless you connected and one thing that.

A

I really wanted to find out if so, this thing can be used to make these images.

A

And to extract them again, but you can also do this. This basically is a command.

A

By we say see, I think, make me a device described by that index file of blocky.

A

Life and what happened is your mobile and I would prefer show that to you. But.

A

Now I'm afraid for the sales of hardly what did that? Xew progress fan and you.

A

Blocking light shows up- and it's called my water depth, maybach image and it.

A

Going to be supplied ssd a and what happens in the background is that csing.

A

Will start downloading chunks from the beginning, slowly blah blah blah, but as.

A

Your success, the block device right, can technically come out it. You can use cf.

A

Design, whatever you want, like you, learn and the accident, it will then read the.

A

Chance that you request authority first, so basically it's a really nice way. How.

A

You can expose a remote file system locally with okay performance. I mean.

A

It's not very optimized, but it probably could be optimized quite a bit and and.

A

Haven't really shown as a local popular with leather like ice carving, but with.

A

Security in ship- well, all isn't about. Having like the question, is what about.

A

The project that all of this is about the disability, making guarantees about.

A

Immutability and immutability reproducibility: all these things are the.

A

Opposite of writers right asses right, but that said I mean, and I could think.

A

That maybe one could put together something here where you building like.

A

It like a system that knows transactions where, basically, when.

A

Actually, actually write, something would collect them and then doing you in excel.

A

Upload evidence and things like that, but that I don't know it's not it's not in.

A

The talk about what I wanted to be right now, but people can build whatever they.

A

Want I mean this is always help you actually like those resources are written in a style that they're supposed to become a.

A

Chef by week, sooner or later, so that people can build whatever they want out.

A

Of this on heavy level like I don't really give you the high level access.

A

Only I get the exigent there's a lot of actress on the series agent. Another line.

A

One is campaign, and it's all because I kind of hope that people pick us up and.

A

Build a little bit interesting, I can supposed to be difficult. Get for.

D

Exam because we've had say my weight, so people could view things together shall.

A

Not want to see no no, but I think I pretend I want three that people instead.

A

Of doing this stuff, they can also try it. You know, be a testimonial if they like.

A

Or some money for http but then translate for protecting, sets or end in.

A

X, what I might turn this in the background requires a kaiser those with.

H

The networks to that, but yeah anyway, that one question was it totally to.

A

Excuse for anything m'kay that, like I mean the next slide of this, the next level mounts, and so the difference here of courses again see a vx is the initial.

A

Of the block device, but the adx is the image file of theorization directory. So.

A

This command will actually take that thing and mount it to you locally on.

A

Some directory in this kind of such somewhere and then as you, access through.

A

That it will get attentions and exposes that is excuse this unit mvp. You know I.

A

Mean ii and a media is the network block device, but something has.

A

For ages and jasmine full of alcohol, but it works for this project, so the.

A

Original idea of enmity was actually to I like ice college when amazing, again.

A

Exposes we're not occupied berkeley, of course, the way any keywords and we every.

A

Request this posterity to the other side, I usually simply to to talk to my local.

A

Ta chicken-sized and then there's local piercing consensus. All the magic was figuring out the chance of entering a chance to become brilliant chance, and things like that. So it uses some concepts of the kernel.

A

Driver that nbd has, but if you was nothing of the enmity, the code of.

A

Protocol or anything like that, it it and take benefit of the fact that it becomes.

A

Provide the way how these the states can implement block conversions by means of.

G

The kernel calamity and right for this job there's a one yeah yeah, just right.

A

For the chance are well know what the presence there was the in this part.

A

Precisely crowds of the image file cuz I'm a little metadata and then really.

A

Just contains information like the elicit ashes plus they're offset. We also.

A

Deformation to tally redundancy only reason why the offset information in.

A

There is in order to have random access, because again, this is not an equal block.

A

Type thing: isn't, it is a variant block type thing. So if I want to jump to.

A

Reservation position where five five five five five, then the only way to do.

A

That is fine, right block. Where is- and I can do that by by section- if I always.

A

Thought it the author than that, but under.

A

Information that there's no information about url, that's what you're asking.

A

The the idea is always the explicit idea. Is there when you invoke see a thing.

A

Until it uses that index file that the store is located, maybe they're the same.

A

Place but called before, but the sdr that's been before when you actually can.

A

Do is on the command line when you're broken, you can specify store, equals.

A

And specify any url you like, and that's why the look you can kind of specify as.

A

Many stores, as you want, they will try them all one after the other, like a.

A

First order: that's something we'll use the next! What their new baby is that, if.

A

You big organization, you can have a little store of stuff that people already download or frequently used, and if that's not as I've, let me actually go.

A

To the internal erbil other, but yeah be the implicitly folder. The video said.

A

Anything that looks at the url and generates a different url. But when the.

A

Venules were going off indication for the alabama that, while I haven't.

A

Implemented should be services. Look over some entity in the code really supports.

A

Everything under the sun they do anything to and actually taking.

A

Automatically customer support page, which is really nice as this tech.

A

Lighting and whatnot really cool to see that I don't really have to care about.

A

That and so now we don't do authentication because I don't know if I.

A

Actually have to enable it explicitly and in in the curl is that required, not.

A

Explicit dangling and it will just work so.

F

Yeah we support variables like we allow you to configure very little, but that's.

A

Mostly because we can meet it, there was a reason to total support.

A

Like right now, you can set the bandwidth limit for dallas, but I mean, if you want.

A

To be able, the ssl certificate change to text I'd be happy to take attached with.

A

The penance doing that, and so we have a fully grow and whatever tickle me right.

A

Yes, that's a very question, so the question regarding whether I support the.

A

Volume and allowing to being this other thing that I brother was the publicize.

A

So I versus come racing we're building altitude to do prices on the local.

A

Network and actually interesting ideas like combining this, that was, that might.

A

Be caused the problem, you know if you have a world where you lots of similar.

A

Devices deployed infant network, like I don't know the seven steps or small.

A

Incision here, they're all the same network and if they all go to the.

A

Internet validation that some kind of redundant right like if one is the first.

A

One and download everything would be much michael, is the next keeping with.

A

Actually and then expand the 7x down. It's not as amended right now, but I.

A

Think I would hold onto it with around, because I don't think that I didn't need.

A

To invoke line that there's a life of service management and I think our.

A

Service discovery, I think cac, would probably it would make a lot of them to learn something just give molly calculated.

A

And look we're not facilities put forth for actually the chunk. It would just set.

A

Our message saying I want this chart this chart this chart and I'm the other.

A

Piece will supply them, okay, say if they have it, so I definitely would love them.

A

For that one day, you're, probably on home, like the other high, is in that different.

A

Thing so I can hold an altercation with my company apiece and that's not what once they're right like. There's no need to know that chime tone. So suddenly we.

A

See it on the network, nobody will care about that until the point where to do.

A

Is download and when you do that with an dimension query, but we can learn a lot.

A

From how providing again anything work, then you said there, but doing that would.

A

Be a key excellent, because, basically we could just do it completely magically.

A

And completely secure, because again, every chunk is always has this like we.

A

Requested through the tech center, even if you have the road turn of pets- and we.

A

Want to give your once again there you can really go faster.

A

Away and not create anything from it, so is that anymore, so we gotta tell you.

A

My intention to have another back-end went to the basically, we can build on.

A

The network and I can speed things up and actually yeah like chrome eyes, the.

A

Steps they do it with the body. I wrote a line, but I still do it. A lot is because I don't know if you have a hammer, everything looks like a nail.

A

Would what everything was like the right thing to use a lot more technology, yeah.

A

But I made a message of eternal life like I: have this beautiful concept of a.

A

Chunk that, if it is proof simple right on ice cream, things are way more complex.

A

Right right because yeah actually have something smarter filters and whatever.

A

Help right so, if I do on see, I take a protocol that just up anybody has that.

A

Chunk, I can implement that need to be in securely and simply- and I'm done with it.

A

Well, you probably have to actually talk to like a cool topic and direct.

A

Connection as he talks on six mark, it has a beauty of see a thing.

F

It does but kind of a cache really.

A

Deleted when you're done with it but effective intentional interest as well.

A

To make a cash and object assistant, if you want to but doing that when of.

A

Course mean that I would have to commit to the format of a cache. And while I'm.

A

Happy with committing to the form of the index files and on the store, I'm not at.

A

The point yet where, when I connect to the cache- but I mean timely- is that all.

A

That position moves everything I'm not doing with the removal. Over 30 I mean.

B

It's exactly really good point, like all of my things that I want to build this.

A

Into eventually it's a caption, you know and backup and basically means that.

A

Every day you run the thing, and it does medically put a couple of your judgment.

A

Servers if we would actually go over your home directory every day and read.

A

Everything alive utilizes chocolate haven't drawn right. A lot of time.

A

Because we have to look at everything, a pile together translational, so one thing.

A

That is very hard to do. This is to make that use case work where you have.

A

Terabytes in your home directory, then there's a cache for that right. We're.

A

Basically saying that yeah, if we are at that file in the end time, is that and so.

A

On so on, then, that's by the way, the hash. When there's no point you don't have to.

A

Read it as long as all the end time to match this rule, so caching is a good.

A

Thing or they need to be more satin like them, you wanted renders, and it's kinda.

A

Crowded acquired to open things up for backup, but for delivering it doesn't.

A

Really matter because images we deliver tends not to be terabyte, they tend. I.

A

Don't know, I guess you don't think like I teased, especially they probably.

A

Had images that don't grow about python magnet bad enough and to doing this.

B

Apart memories, during the build process to really have a wall that would years.

F

Ago, yeah yeah now embarked indeed well.

A

No, it's a cash, it's actually next to the place where we have to place it in the.

A

End so we can do smart things to the problem, so the president marking t was.

A

Whoever there's no benefit of not going to marketing people, but we never use.

A

Left hand, because best time is a small positive. These things can grow to a.

A

Particular my source employed, oh yeah. Well, I want really nice thing that is.

A

Also, does it trouble, you know one is that the area we're supposed to be used.

A

Is it now that you do the conjugal teams set up your hands? It's a position to be.

A

Position that I already mentioned, and these decisions has vertically.

A

Large-Size immunity, heart of the cs, part where we have that the valve is.

A

Installed in these petitions they usually much smaller right. That's.

A

Because you would want to add room for the future for growing things right, so I.

A

Don't know you have two gigabyte be card in there and one you get, but this one.

A

Wants to get a 32 and the first one is built upon omega recommend. You know: okay,.

A

You still have five in megawatts to grill over this as time progresses. Now I.

A

Mentioned that represent ability, medalist tongue goes to me. This is kind.

A

Of a big thing, because if you would actually use shot to a little thick, some.

A

Like the shell come out on death sba, one more whatever it's block devices called.

A

Then it would actually calculate that checks of not only on the access file.

A

System that, but of all zero, the carpet right, let me know because it makes me.

A

That data, but is also not be because these protections will not match right.

A

So we added to say I think, there's a little bit of smartness that operate on.

A

Block level it can actually understand the super block of silicon systems and.

A

They figure out the actual size of the thing and then we'll baby. We fall back.

A

To the size of the block device, only if it has no true and that's kind of cool.

A

Because maybe means I can run ca, think dieded onto somewhat device and it will.

A

Actually calculate you need check some of the houses upon it and ignore all the.

A

White space, with my concert, this is a nice cool feature. I mean kind of support.

A

Right iii is whether that a couple of other one, but there is not something yet.

A

I think this one's much my last slide made sure it mostly dc. It has one of.

A

Them obviously, with need to come next yeah. Eventually, you want to be in a.

A

Dispositive and then you need to remove the tank, but because the terms may be.

A

Referenced by couples and nexus remove the chancellor. Never you know in.

A

X is less than actually matter from the gic. I feel the difficulty that I did not.

A

Somatic it, and actually, if we want to make it usable back up that I need the.

A

Caching, so that was mentioning earlier, but it's our only encryption.

A

Right, like everything I talked about right now, is we got encryption. The.

A

Assumption is that if you deliver proton or anything like that, sure doing, the encryption are making to be at level. But there is not really need.

A

To to encrypt the actual data itself because of the protocol ball recover.

A

That so backup and a couple of other use cases with them cut it anymore.

A

So backup is really essential that the data that you backup on a server is.

A

Encrypted when your key in the sort of know the key times- oh yes it, I just.

A

Going to happen that I mean the main goal of totalitarian support with.

A

Instability and that I was kind of very different, but also very similar news.

A

Page right, because if you do image to the radio, thompson's always only have a.

A

Lot of very similar, directly trees, let's make some of a backup right. If you have.

A

A lot of racial of director street because we do with that help any day so.

A

That's kind of where it fits together see a thing supposed to be done. Couple.

A

English kids in the world, but it's supposed to color still a couple like a.

A

Range of these cases and backup and image disarray of certainly both of them.

A

Are supposed to be covered yeah if we do, if you do with that out.

A

Stuff and then I don't want to then six are economic hard to do and what we need.

A

To change is, instead of actually calculating the sha some of the blocks.

A

What we do is we cut it as a map of these blocks. We need a key pass on some.

A

Other key of the hash marks is actually equipped decree that they wanted useful.

A

Backup and we will have to compare encrypts the individual blocks, which is.

A

Pretty obvious: how to do that and the this chunking.

A

Algorithm needs to albany key so that the sciences or the chunks do not reveal.

A

Information of might be in that stream, but these.

F

Strings are already proficient than we have the prospect of the time of.

A

Intersection remember: there are backup systems like that already in place again.

A

Much as wouldn't like they've anything that I was talking about the probabilities like it's all implemented elsewhere in some form already one.

A

Backup system that does pretty much what I'm describing here is power, snack.

A

Toppings from some open, bsd guy and he activated visited mother resources- here's my difficult, but it isn't it's his way of living like he most of that.

A

But tarzana kind of does the same thing for backup like he doesn't care about.

A

Them into the rate he only cares about becca and because target written by the guidance road meant are. He doesn't.

A

Really part from tar because tars everything to him so he says: do dope.

A

Emily consider him in a dynamic, customized means of group, yet incoming.

A

But otherwise, like from the cryptographic on backup detective, it's.

A

Excellent, and in this way I see a singles gelman, so this to that model and.

A

There are systems like that as well, like any nick began like this. If you a when I.

A

Put it on your hand, one of the most frequent requires a godless. This is.

A

Exactly like predict silver zone, and why don't you just use shell script in that.

A

Project, why do you tell us with my fingers and.

A

Yeah I tried to my home, I figure out all. Is this a good one somewhat like this.

A

But there's no tool that can you this was nice, so yeah. That's the idea.

A

Officers, it's the way the team to put together that is different. There are.

A

Another thing that might wanna do eventually hit is the online executors.

A

And home speculation so kind of some of the second thing like if you do regular.

A

It's called your home, directing on some server. Many can be played on another.

A

Server like on a client they're in automatic kind of transaction ways, there.

A

Is yes, this would be an accidental etiquettes yeah? If you do this kind of.

A

Automatic synchronization will had a lot of popular. It's the topic that that what.

A

They call them like my google drive and dropbox currently cover, but it could be.

A

Built on this, actually, I think very nicely, and the big benefit would be that.

A

This server and can find hd dvd and you don't have to trust it because all the.

A

Stuff and we stole there would be encrypted before tools there. So yeah.

A

That's that's actually, my last life. This is, if you want to know more about this.

A

Like a first url list, later decided aligned right so weird me as we got.

A

Started, I have it something like a guest that many of you worrying whether its.

A

Kind of kind of just talked about, but in text form then under the I want to get.

A

On your elbow, yeah keep on the source code, it's been packaged by a number of distributions right now, and it has a modern history, already development and.

A

All the stuff from them again, I don't attack version upon to pay what we.

A

Want like the first version very recently, and so yes- and this part that I.

A

Just showed you is not in the version of return that came after that.

A

But morgan came this again guys new software product is perfect. How many.

A

People tested in size means we have the test. We did find. A lot of things were.

A

Also, of course it has to be, I realize you do you rely on sight. We do.

G

That tonight something move to do. Oh, yes, I could want that myself, a three um yes.

G

Seems like I was the reason I didn't announce it on your own, yet because I.

A

Wanted to be sure that I can keep committee with my informants. Let's fan.

A

Since I didn't argument people, I gave a couple of ideas, so I will probably, as.

A

Extensive but I just had to do an incompatible life, so I do not give to.

A

The city, but yes like if all of our locality, like it changes them, don't.

A

Explode all across the divider 38 inches work life. Like I mean the thing is like.

A

Eventually, why I want to put together, like I just want to monetize how, how.

A

Building works right like because regardless is a.

A

Desire to you by the container reserve, whatever else I think little robotics.

A

Passion to be all amazing to memphis work and there shouldn't be different.

A

Little containers and ign and an in-service the chola, should always be.

A

The same trusted and like like, like with trust ability built in different.

A

Verticals and right on beginning so I'm kind of like this is one building block.

A

A very naturally long term that you can usually be given by the way it is most.

A

Parts into these, it's part of the tiffany umbrella project obvious, but.

A

It's a mexican hat upholstery. You can't even without a comedian, not.

A

Sure why would either I can sell, and it's not only right now, I'm having to.

A

Take patches of this one purposefully to have our uniqueness, but I mean you may.

A

Consider some one reason: we're like things like open hat for those who know.

A

Are supported, I don't really want to have like huge comfortability accessory in that. I'm happy, though, is it. Has its method of covered abilities exactly yeah.

A

So this I said that this torment- they they were some of the bits that we.

A

Actually, saving store are things like adults and file attributes likes for.

A

Those who remember a system hidden archive regularly, so actually I support.

A

In the entire file format, so that you could make use of it of windows to you,.

A

Might want to that. Do that the reason why I did that is.

A

I actually want to be useful to me, realize a a massive property and, on my.

A

Laptop, I always will have a competition because psi requirement of csp, so my.

A

Appeal is occasional, do that properly and actually still the metadata that is.

A

About an effort is the same way as we care about the meditation that we have.

A

Set before so yeah, that's all certain that was portability in the content.

A

Somewhere and yes, there's nothing boss, people from committing mental health or.

A

Again, I would be willing to add support for treatment, other chemicals that have.

A
