A

Later, in the day, with their machine of my head and then they point out because it got actually lodged it was, he said under microscope- is it was like a plastic disc and it got lodged side into my eyeball.

B

A

Pain, crazy, my wife was out of town, so I drove myself to the they are they put some like anesthetic into my eye? Immediately, the pain was gone, they didn't, then they, you know, took it out and they told me to go to the drugstore to get drugs by the time. I was in the drugstore.

A

I I couldn't drive on the highway home crying so which.

C

A

C

From the bottom be a bunch of the Cindy sings, but ah we should talk with Eric Earhart, one RV together yeah. We should probably do like a good overall thing in.

D

Skies and then you'll get a message.

C

So, let's start we have free networking claims which are so ah I should say simple, but yeah I, almost people that usually can go down on Obama number, four from bottom and then one second from the top or third from the top. There are very basic reading, even higher up higher yep. This one.

C

C

If you want to the only alligator naming system, pretty straightforward, the only different or advice might be: does I'm a teapot versus the start from the top on the vallarta status is I'm used, so the casing is different. If Damon cares.

A

A

However, we should sell it out. I am used.

C

It's probably easy to read a visit, he copy/pasted votes actually in majority and what's actually as well on Wikipedia, it's called capital, I capital m space used and that wikipedia article is about without.

A

A date yet wikipedia article about with RTL video about yeah yeah, something like that.

D

Didn't all it you were that popular vpat.

E

This is really.

D

E

D

A bunch of unit.

E

F

It's sitting there for two years: three months, it's kind of a person. Yes, so the casing.

G

Isn't inconsistent HTTP 2 to 6 is I am in sit, which is Vincent's, manipulation used in HTTP for 16 as I'm, and then I am a teapot.

G

G

I am is not enough, you know I resisted it. It's instance. Manipulation used I, am you see, but not in 44:18? It's the contraction I'm without the.

D

That case I think it's cheating, but it's correct.

H

Didn't you write the guidelines first off yes, but not about.

I

I am used like we thought you had a guideline to set uh acronyms lesson. Three syllables roles of her listen trailers were also you know,.

D

Was this really is about right? Now? Instead of somebody took offense that I always specialist case in your lower kids or like that, we.

J

K

Have done that.

A

D

A

Right well, I have to do research on the difference between variations, shortenings and there's something else. There's called taxonomy of these things if you study linguistic books, otherwise none of the guidelines would make sense, but then I read the thing and I fear of Chanel. After the fact.

C

Right so here we go here something similar. We are adding constant strengths for education, Jason application. Somehow we have text, slash XML will be researched or research bunch of things that might be useful. The application JSON is actually useful because there's on the second floor question this confusion. What should be used and they're like you- know, four four or five variations. This is the ripe on based on I, believe RFC or something this.

D

Is actually such a thing is a correct month? Well, they're mime.

J

Types dictated by RFC's: yes, oh.

G

J

Then there's gazillion apotres that people use so yeah I always have compression at mine times are so.

E

J

So bumper stickers that whenever.

E

You feel like it, but.

J

Sometimes servers.

E

Are kind of yeah I guess it's true, like the cryptographic time, stamping that says.

L

This will be the five type of the requests today.

D

I mean, and this away is an objection.

D

Except the Correa's.

A

D

Seems to be in the right spot was much to argue, exposed.

M

To application type and for just tight call application.

D

Was initially it's in its basic media type name story application to us so.

D

Given that the.

M

Type already existed when.

D

M

Just curious, I surprised me again and.

I

C

Switching the default to version 2.0 and let me start discussing that we figure that you know figure out that let's do a default and basically you know slits it to deep. You know kind of not system default by the implementation, people or.

M

Else, every time I had something that floats like this. It breaks people. Yes, it.

C

Mike I think so we can exchange the two total anyway right, you know, so they cannot break people. The question is: if we want to relay and stop changing that on regular basis and saying, like you know,.

D

What I would do is I would change the value from defector name from before to highest available or something because default is a policy right. This is the, if you just say highest available. I mean that is always true, but it did may not be the default. Well.

A

But it's not clear whether it's going to be true, so imagine a new version is released, but we don't change. The implementation. Api said: take this thing: isolated.

D

Means highest available.

A

D

Supporting right guys available doesn't mean necktie.

J

Para mental support only right, so you don't get a robot so.

G

I mean this is easy for.

J

G

The question is for framework: are we going to do the once we've added it, and it is lot to a thing to talk to a thing. Are we actually going to let it move in which case says what said it always lights us know.

D

G

D

We could still see own best off the ephod versions. That say one one by hardwire, but there's a constructor that takes an HTP version and the customer says I want the highest available. We should let people do that at.

I

That point: should this actually reflect the highest available and not be interactive.

D

Maps what I mean to me like the victims, like the problem, is it's a sentiment right until it is such a thing as in next video as a version, this.

G

Is static, read-only icons, so there should you contain, so they will pull the value and then we'll get whatever the assembly says.

K

I

Mean, or there are scenarios in which someone would want to query with the highest supported versions for anything right well,.

D

I'm, nothing like how they'll mail this. This is not the right API. For that I mean you could argue instead of having a property to just make it method like get highest available, but then I'm not sure we can do that because it depends on where it should be version. The type ships, armor implementation, that's right, so that so, let's imagine HP version is a thing that ships in box- and we can't change it. But then there is an auto ban, it should be client or something, and then you can accept the HTTP version.

D

If you just get a sentinel value, you can order it. If the SAV.

A

Is forced to produce it in your screen? So how do we imagine people using this API like? Is it even like shouldn't people be explicit? What version they want.

C

Well, we they are overall or I, think it's appropriate I believe, but in general they don't then don't set it. We have defaults right now be default to one point one. So the point is like hey, you know one phone or less per day. All 2.0 is faster, so let's switch it to 2.0 and with that we want to give us about people opportunity to say I. Can they set it explicitly to say like yeah yeah? If you don't care, you really want to latest greatest, like part pastor to default. That was like use.

C

Whatever we decide is best.

N

Or they can just a check if some specific version is already supported or before use it right. We've.

G

N

Had this probably.

G

Before because HTTP 1 1 predates that.

D

You think I'm, a HP versions are not like coming out like crazy, generally speaking and yet because.

O

What we're highest order and show highest available, but that would work to me.

D

To me, it's really I, just don't like the word default, because it applies that this is the policy which we may not be able to actually.

C

Well hold up nightcore, it's gonna, be the policy yeah, but okay.

A

Sure yeah by changing defaults over there is like yeah I I can just see people trying to do if highest support. It is 2.0 them to something otherwise.

P

A

A

And 3.0 is released and that the code doesn't work but.

G

G

Hey max max forever, we still it's the you pass it into the library and it tells it just do whatever you want to do, and then you cannot use to query yeah. You have to do something with it and ask that what did you actually do? I.

A

Have to say I'm like I, don't mind this API, but I'm a bit skeptical. It.

P

A

Used for query and if I like you know, we have existing ideas that return versions I understand that they need to change, because we want to move to 2.0. But if I explicit this like call some API and that I pass in a value, I think I would like I, don't understand what would be the sign for I. Don't care just give me the highest if.

G

We want so for a query type thing and we need to live not as static here. We need to live on the implementation type, so we live on a ship I used.

Q

To be called a handler because oh yeah the hand or whatever in the lair.

G

Actually does the work, because that's what would actually know what the best that it supports is, and so maybe that's a better answer.

A

As I said, I don't feel super I mean you know. Possibly there.

R

Are scenarios it's just hard for me to do it better? If you have like a supported version, you check for some.

N

Specific versions.

G

The Sentinel being called like best-supported, but her.

G

The difficulty could be that, like you, could be in the state where you think I was working but you're not confident so like what would work if someone passed it in, but otherwise you're going to say, 1 1 is your best support and like trouble is at some point we're making an opinion and.

A

Also like so you know the highest supported, let's say it's 2-0, you compare it to the highest supported and it's doesn't compare to equals. Isn't it weird yeah.

S

A

The current behavior and stress in this proposal well.

G

I mean that'd be like comparing. Is this timeout bigger than timeout that infinite, so I? Guess it's like? Oh okay, but I believed it have exceeded my timeout like no time out that into its negative one. It's both greater than n less than all other entities.

D

One thing that is problematic with like having central ages is that people would probably end up comparing the sensitive ages themselves, their same. Some things like edge, beavers and highest supported, equals a GP version version 2.0, and it will never be true right, so we probably should rename into these two something, like you know, use highest or something to make sure that it's a you know an instruction rather than an actual version number, but maybe exposing something that they do itself is not a good idea. You shouldn't.

G

Set any it's a different overlook, it doesn't take the burden yeah.

D

I don't know like do. We know how this looks like I mean if it's a structure somewhere, then it may be hard to do, but.

C

All the post, recomm.

D

Like the question is so imagine, instead of having this API here at all, like whatever takes diversion right now offers the different property. That's basically like, instead of having a virtual, you just say you know, there's another thing you can say you know use highest equals true, or something or.

G

We take the thing that takes a version and make it a little bit. It's a noble version that donates do whatever you.

D

Want right, I mean I, could imagine, there's digital layers that don't care if I don't make the thing that uses the HTTP client, it doesn't actually customize anything.

D

Possibly experience for you know, their consumerism is one thing that works yeah.

D

What did oh actually anime should be was the most rewrote.

G

It it has nothing in common okay, so.

F

D

Just you know better Cooper and wise or like koala protocol or whatever it's binary instead of text. Oh welcome to the 21st century,.

D

G

Alright, so then.

F

G

Still has headers and content and.

I

Native it reflects it assumes at some point that you had connection some sort.

I

T

A

Except use house support, it sounds like you know it. It only looks good on the con side. It doesn't look good when you look at the class with historic fields. Hdpe 11.1, 2.0 use highest supported hmm three nouns or noun phrases in one verb.

A

So to me, in my mind,.

A

For the person.

P

A

Is to grow like show AP is that would consume it and kind of some common scenarios like. Why would you even pass it to some API like? Doesn't the API have a default, or should it have any.

E

D

There we go and all we should pull in one of the notes unless.

P

D

Becomes constant.

D

D

And I don't know what else we could do. I mean these are really the only two options.

A

And you know add a comment to provide examples of usage and I like IPS that would consume it.

P

C

K

And we do the shooting the first ones first, so.

M

D

Let's just try to look them all.

D

D

This is really the line. Api like I mean.

E

True mean it'll just.

I

Give you like an impact or something or long so there actually is an API already. That gives you an inch back because it's basically compared to, but it produces.

A

None of compared to compared to compared to the.

I

Values yeah well, then, so, there's a there's, an API that basically takes right, left and returns a difference that already exists. However, that encourages.

P

I

That you don't necessarily want opportune or min hot code bouncing. This is done either modding about thinking.

A

Whoa was just asking: can I get an integer representation of dodges and just know.

I

You so there is a two pointer. However, you can't do that because of the garbage collector, the node that is around so.

N

I

A compare for like an actual less than greater bill. That's actually good point. I have you would so you? What would it be like less than wrap, yeah.

N

I mean, like is above means that, if the fittest above the second right, which is as great as insect yeah. But what would that look like when you're waiting like.

A

Our compare methods compared.

B

A

Reps and returns and 8 is minus one select.

I

One like I I, actually created. That is the very first idea here. The problem is that is incurring overhead in hot code hat.

I

Happens is you have this method which returns -1, 0 or 1? Now you have another comparison after that, because all you really cared about was if one was less than the other. So now you actually have two different.

N

I

Be honest one because you just provided the pointer right, the point your left, which we already have an API for that and I tested it, and it gives bad performance and moderate amounts, the reason being that it incurs an arithmetic operation where we really just want to direct rehearsal. So what does the LT being more expensive? The sub and test yeah.

G

U

N

So so that imitation, how you implement it like is about what you would do inside a it's.

I

Written in il it's just a simple comparison like load, F, load, R, 1, R, 1, R, 0, load art, one of compared less than.

G

You so I mean doesn't need the same argument of you can't call two-pointer, because it could groove mean that this ApS effective of useless. No, because when you're, when.

I

When the, when the Seattle, our detection, the two arguments are actually references rather than pointers that make sure that they're both correct as far as juicy goes before the computers. Yes, but as soon.

G

As it returns back to your function, compaction to not have that same relationship, so by the time you get the answer, it could be false or wrong. It.

I

Could be, however, as far as for the particular scenarios, where we're using this, it's actually okay, because once an area we know for a fact that we're working with the same buffer, we just want to know whether we've gone past, the midpoint of the buffer. This is the array dot. Reverse example, basically, where you have one pointer going from the beginning, one pointer going from the end eventually they'll meet in pass each other, and this is a way to tell if they pass each other.

I

The other one is used as a and copy to implementation and the same thing they're like they as long as each individual comparison is correct as far as pcs concerned than everything I mean it is, it is a really low level, API right for use, I.

D

Mean like the discussion, I just can go with like the naming discussion. I think the own aesthetic or the other names have the same problem like I mean, if you say, is less than lady one. You really like that. It still gives you the wrong idea of what the API does probably breath value warning wrapped up. But well, that's not the point. The point that Eddie made was, if you read it like this.

D

Basically, what ends up happening is you say it's below left but like it's basically left is below right by the neck, bent birthday, but less than or X is greater than like all the compared two methods have the same, although less you have two in.

A

Your head, imagine this in this is an infix operator. Well, except I. Don't think we use in the framework terminal below and above use, less than and greater than no sure like I mean they are synonyms, and why would we not have to convey that you? What you're, comparing is the address, not the value they are pointing to and.

I

Below it above actually are is the terminology. That's actually use accusers. Well,.

D

That one I care less about, because I mean we can just make whatever the thing I mean we could also call the lake is, you know, is memory below or something or isn't below or has lower address or something it can also just put the name address, yeah the.

M

Trippin unsaid.

K

Addresses alone, I wouldn't be horrible, closer.

I

Okay with it then or or allow us to put my all consumer.

I

That's what the introducer well.

E

Good luck, password.

I

I mean this is.

D

All right so naming the edges should be involved, so unsafe is below, and unsaid is sorry. Unsafe God is address, Allah is address below.

M

Works for me, why not its address less she's recalling address we? Don't you do it also.

A

Works I just listed it's longer, but.

N

We already have a class is called downs here. Yes, yes,.

H

Well and now, from now on on new api's.

I

Daughter, so you'd prefer less any greater than as opposed to like. Before and after.

A

Yeah, because less than and greater than this existing terminology and below and after seems like a synonym for less than in the context of addressing settings for the pitman pageant generated, it.

V

So to call it a disorder reference.

D

Right we're comparing two references. Well, if you say reference again like we're, comparing two addresses. What are you comparing? The video of the reference has a variant of reference reference list. Yes,.

W

So you're, comparing.

D

X

I

The difference.

F

It's yeah, you can delete it just.

X

P

You never knew that no.

X

Life-Changing thing: yes, it is you just copy one.

C

Time's up to magically extends, but almost sometimes so yeah.

L

S

It's correct: okay,.

F

So it's school again.

L

All right, happy resistant, yes,.

L

N

C-Sharp cannot have like operator or command references. There is no.

I

Values, so you could accurately you could do like if a lesson the threat, but is comparing the values that are pointed to by the by the references right.

N

Another enough I cannot say like riff, a design with.

Y

K

That seems someone walking or drinking enjoyed RL. No, no.

C

No can actually jump obvious Matic on you are on the Skype call, but you're not on the Skype call well.

D

It's capital because I will only for 10 minutes and nobody was on the phone. Okay. Is there now? So, let's do the thing, a jump in the toggle, the.

Y

String stuff, what they do.

A

You have to fight excited okay,.

O

Are we going anymore order here.

D

I, take that as a yes.

B

F

Oh no good, hello.

Q

Can you hear us.

P

Yeah all right.

D

You may potentially drop in and out because guide this thing sky and I'm using a Mac and that's not healthy.

Z

D

That's what I meant using your Windows on Mac, so I'm asking for trouble.

Z

Yeah I, just conserve shins, now moved on to new opportunity. Now so I haven't had a full jump. Look, it was the only thing I could deal with. This is reciprocation text. Input should be properties and all fields.

D

D

Yeah other thing otherwise looks reasonable.

A

I did I have a question about the time to live. What what is it.

D

He's on hold again because sorry you were on hold because again, Skype is nice guy, so.

Z

What does he I don't know? If you heard me anything I could see with this said, shins now I've gone on to new opportunity, so I'm coming at excuse me fresh the only issue I see. Is this indication text input and failed to be properties? Yes,.

D

And then crystal asked what it's time to live, what does it represent?.

Z

You refresh the feed.

A

And it's like an advice from the server is: is that what it is yeah? This is actually part of.

Z

The RSS spec, which we historically never had implemented it's an optional field, and it's like how often do you have to refresh this so like if the feed was putting out new articles like every few hours they might time to live to be you know an hour long, but then, after you get outside the publishing hours, they might put it like up to eight hours or something like that. So.

A

Ways it an int and not because that's time, cuz, that's what, since, but.

Z

We could do time span, but yeah. Let me let me look at the actual spec, because the thinker's just I think was just an int in the spec, but that doesn't mean we can't represent it with hands. Pal I mean.

D

Clearly, the spec has to decide what the India's, but it's minutes or hours or.

G

D

G

Problem, like we're afraid of somebody wanting millisecond precision when the specs of this minutes, and we should at least put what the unit is in the name. I.

A

Would just change it to a time span because, like you know, it's a return value, so it's not like somebody can suddenly start returning weird values and we just return. You know one hour and it's so much easier to deal with existing within existing api's. We.

H

Like object model collection, do we care.

U

D

Else would you use.

R

D

Is because it's implementation time.

Z

Yeah, it's actually called TTL in the X in my document and number of minutes that indicate how long.

Z

D

Z

All right say again: it's tight Sam, it's a number of minutes, the TTL field, and it's how long you can cache the document before I'm to refresh on the sauce.

D

Yeah we generally don't like, like ins, because then nobody knows what the unit is.

Z

Yeah I agree: I mean.

S

I think that's.

Z

The only problem we have it being a trans man is, you lose fidelity like syndication feeds, isn't just for reading peach. You can generate feats as well, and so, if we put a time span and someone puts in seconds then what do we do.

D

Argument not exception, I mean.

C

D

You could do is like when you know like when of you up, I mean when you do the same operation. Logically, there like a safe method or like how like well like, when does this effect happen.

Z

You build your whole object model and then there's an API, which you can't think of right now, where you generate the XML in one shot, I see so.

D

One thing you could you could validate and say: if the timespan, it's not like, you know an integral, basically number of minutes and you blow up from.

Z

A property setter only allow time spans which have no seconds or milliseconds component.

H

Documentation that you, what that you're supposed to put minute documentation if there are any more than minutes and if we just call total minutes with cast two minute mama. Well, because.

A

Junkie, substract asian is silent like if you don't read the docs, it's kind of silent and you may be surprised persons, they exception. Just lets. You know, and you see the exception message says you cannot sell the team for anything but multiple.

K

So that's anything lesson.

H

Thirty minutes- and you know 30 seconds sure, so why punish them and just not rabbit down to pretty much so they.

I

U

G

It's the exact same argument.

E

U

G

This show so the yeah I mean if we think that we would throw on the granularity problems and I think time to live minutes is fine and somebody.

U

I'm I'm good with either I would die with loading. Ttl is like great four.

G

D

D

F

Does copy to throw enough yeah I forgot to reassign nice I was always over already simple protector for bugs.

Z

So what we think that time to live.

A

A

Expires or something I don't know, 19 years again,.

D

I crime law perfect. So basically, what crystal just said is you would throw.

I

The pardon does, the our suspect was the maximum value, the BTC elephant.

Z

No maximum, just an integer of minutes of.

I

Any arbitrary way up to and including it does, it doesn't say, like the integer, has to be like ten digits or viewers.

P

Okay I mean we're all about that.

I

Like- yeah yeah.

L

All right, so you take time, span.

G

Already, that's fair, so throw if it's not an integral number of minutes.

Z

Okay, so he's saying make it timespan and throw when it.

Z

F

G

P

Or zero, presumably I.

G

P

Z

Zero, just doesn't make sense, you're saying like because that could trigger continuously fetching it like I, think there'll be okay. As long as there's a very explicit they asked of zero, we aren't truncating, it.

N

What to suspect you say, yeah.

G

Like just whatever the minimum, the maximum is right.

D

There sounds like the video is absent, like it's almost the same.

S

Wouldn't be sensible, then also one is not about it. Bother.

S

Z

um I think I think you could argue varies reason to allow zero, because, as its defining, how long we can cash for a zero value could mean don't cache. Miss.

P

So, like you know what makes sense on that, we're just pointing out that.

G

Negatives, probably, are gonna, throw and that's where the that's not integral. Minutes comes in right.

Z

All right so just make them properties and change the time to live to I'm, fine yeah.

D

Yes, so I just actually do it, so you had the notes. I just commented: okay, all right.

L

L

O

Yes, rather than an API change, especially since the string cupressus one would only live in gold if, anyway,.

D

So, regardless of the actual shade last week, we discuss whether they can little memory extensions right, I think we could include it there. The answer is yes: yeah.

O

Yeah, so all the ones that don't require utilization can label memory, extensions, which is the first half even.

D

Though it's like, why would the other ones not be able to live there.

O

Because they acquire the dimension machinery, that's listen for so there will be dead core. Specifically they can. They can be exposed from memory, trations short well yeah. It just means that the rest subversion doesn't neglect those API systems. We can do them all of that unless we essentially copy and have Pierce lower just to have parity for portable ApS it another thing somewhere is. The memory is already split right in terms of fast versus worth limitations. Oh you're saying it's still exposing in the same slot, so that would be a PRI voice, identical right levels.

A

Your interpretation yeah, what would this slow API do? It will copy into a new string and the constant you call the stringer yes, so it would not be only slowed with the allocation. Oh yeah.

O

A

That that worries me a bit because kind of the API signature implies that it's not allocating but maybe ice. Okay.

P

E

A

One for you could maybe.

I

I

A

I

So I thought your argument was: they were afraid that so scram would have really hurt their processors know.

A

These IP is like even with fast pan, if you called the API, where you don't have a well, it's correlated because fast found in the advice IPS at the same thing, but it's I mean this has nothing to do with the slowness of the span itself. No.

I

Life I guess I was assuming that if you were using faster and you would have access to be the underlying right.

A

Well, if you use the new core CLR, you would actually.

O

So I'm the point.

A

F

O

Close by having allocation, all-you-can operating with AP is and the slow spam version knowledge.

A

Us are located at Olivia, letting I. Guess it's fine, because it's temporary I guess I mean it depends on what you want to do. If you want to look yeah.

S

You could also have the API throw no.

A

No, when did you drink this kool-aid.

X

Well, then, you can write.

X

A

Can write portable code, but you cannot execute it.

D

The point is you: can you just have to write an if check, rather than a negative, so easy? What.

N

Will be, is a chicken just.

D

Ask the runtime ask for the runtime like if its core, then you do it. Otherwise, you know.

O

L

O

That Yan had was about the replaced API, which he said that these are usually convenient. Cp has that you want just play around with, and given that is, gonna be a CPI. The signature is quite complex, especially for the one that takes screen compress.

D

Because the wrong word here like it, then.

K

D

K

D

I would say well I just debated for self by the neck. I'm I'm still not to the api's, are super useful, but I think from Crystal's point.

D

Represent an algorithm that you know if you want to implement them yourself, because it may just be five lines of code, but boy does it suck?

D

If you have to debug the bones like all the time I mean, is it may be tedious to call, but that's probably easier and, like you know, obviously this is one very obvious where you can call them brushes, oh and even have to find the bounds myself and I do the math correctly and, like hopefully, I didn't it up, and so in that sense like it may be worth it to call the API is just so you don't do it yourself that doesn't make them convenient, but you know it makes us.

D

You know convenient in the terms of not having you.

A

To give money out of them so I have a question about the boolean, the retain returning member members. Why are they not try because I assume the boolean they return false when the destination buffer is, for example, too small right, so there should be tried right so remove, replace.

R

Had left, okay, those ones yeah, yeah,.

O

R

Was a string good class, the.

A

Ring again classes.

R

A

But Oh string ap ice, no no string ID is are not the same signature because.

R

The allocation is showing the same name.

D

Is doing the same functional true, but I will say that to me this is is what is more argument if you get whoa the name doesn't matter I'm.

N

Not talking about sourcing battle I'm talking about like somebody trying to settle for something about layering guys has a place. I mean so well.

V

D

N

A droplets, as soon.

D

As you open intellisense in you and you try pad left, try pad left will show up no just pad left. If you call pad left yeah.

Y

Are you have left will.

D

Show up there's a name so.

Y

D

Just too intelligent you just you know, type in pad left. We will show this API have attributes of try and then select. This is more argument for. Can you discover using the old name as you can, can you get code to compile it continuously? No, but that's true regardless. So in that sense, I would argue that the then, as long as the name is included somewhere, I think it's fine. We made everything out there. Try and yeah I think more consistent consistency before rehearsals.

N

So if we have the freedom to change this again, so I would suggest like like yeah try to place, but I would add, also ordinate to be very explicit, because this is very confusing in the string today. So people using the place and which is does organize stop. If you didn't pass any problem and we will expect it to a work in your culture.

N

A

They possibly I'll tell you my concern about it. If, if we just add try you kind of like learn, it start using span eighty ice and we learn that they try very hard, not allocate their first versions of api's that used to be without trying. Now they are trying returned there. So, but it's kind of you know if I saw a method of this type and it was called, try, replace I would be like okay, there's just a version of replace except it doesn't allocate when I see, try replace already now I'm thinking.

A

Is it different than the replacement string or it's the same, and now they just decided to suddenly add the ordinal qualifier to be fairly lucky, but.

D

If you ignore span, you just look on string when the technique direction. Today, pianists in Kerala no I mean given the ordinal is the term they have used on troll, firmer, already I, don't think it's a.

G

Huge jump well, but I mean if, if it the comment says, does exactly what strings that replaced us. So then.

G

They had the word ordinal if we're trying to distinguish behavior the.

N

Other idea is like moves. This signal, I mean.

N

So it would be explicit all the time.

G

Except those are in the list of api's that might not make it too late. Yet.

D

Well depends on. Let me do this fight, I mean that's.

J

Just a slow version of that.

D

J

G

Ended up any other market.

A

Yeah, if it's ordinal, he could actually implement it without access to.

A

It will be just lower because it will go. You.

H

Know chata by child surgeon so.

I

Realistically, are these actually going to be packs in of our knees in general, going to be backed by real string objects? Just a little, you know sliced views into them.

I

What was going to get instances every moment as a charm, because it's their back by string, then what you could do is an optimization is if you can pull out the backing object.

I

You can call into the actual globalization aid guys so.

A

Is it try getting them on.

H

A

A memory we don't have try answering well.

O

You know we don't have it don't understand.

A

We have it on memory, we look at it on memory, oh I, see but not on span. So once you have a span I, don't think week, you.

H

Can we can fish out the string.

I

No I mean for for slopes and I. Believe sand is actually backed by three fields: an object, an absolutely don't. We have internal access to that object, field. Yeah we do so. We could fish it out spam or real Michigan, so slow spider would be fasted. No.

H

I

In case the snows have to be backwards and.

Y

Trust fun with.

AA

I

No, his best man would have the property API, so would already just be passing I.

O

He's right, good point right. So, if the, how do we know that okay, yeah at this man is backed by a string object? We don't need noodle cops, you don't have to do a copy if it's not a collection object. That's.

I

Clickable advocate okay.

O

I

I'm, just kind of got challenged that I think the majority will be back by string objects on well. So.

O

So specific to try, ApS I would think that only the mother returned might written should be called try, and maybe we don't even want both those are. You can do a costume check beforehand.

O

I mean like you, either need to return, boolean or grow right yesterday. The cat left remove. Those are ones that you shouldn't be out. If you should be returning boo or not, rules like gives like coffee to.

H

Right we we don't just do nothing if it doesn't it's too small right, that's running so, what's the total weight in.

A

O

Left under right, so you're, how many captured you wanna add is based on the total of it and your input. Oh, so it's total width of the padding on one for each side. So let's say throw that is 100 and your stand is 20 Q PI by 80.

O

Total it is the same as the specialist.

O

A

Know how much it's gonna grow right.

O

Symmetry move, it will I know the details have by trend and bytes written will be total with that's right. Irrespective of what source will remove. I, don't think that's true about remove yeah, it would be start index count minor impacts. Oh.

A

Because I was thinking about replace the onion, yes, that's right, it felt disparities, replace relays can grow so now only plays should it be operation, status, kind of API, but I.

O

Was going to ask somewhere ah the thing, is it doesn't have any of the other states? It only has if it's not not enough definition, but should.

G

It, what did it make progress yeah instead of just a board, should you be able to continue like oh I've replaced the first from the first. You know 100 characters, but then I ran out of destination space. When you resume, you should start at 100 character mark, but it goes should make progress. It has bite Regina as output.

G

It's a parameter. We have any of our span tribe things that return false, yet still did work and promise that they did work. I, see you're, saying they all return off in shadows when they are promising. I think the ones that we have if they return false bytes written, is zero and that they hopefully didn't actually write any bites before saying bye to zero.

G

So, like that's just.

A

A concern how we're going to implement it and another thing is so the photo replace can the source and destination be the same buffer, clean.

L

G

Or worse, going to be not the same, but overlap.

N

It consumes us another zombies symbol. Yes,.

G

And I can see your shop is very clearly destroyed by overlap. How does it affect the ignition well.

A

It's not clear from the API right now.

M

Whether I think it's certainly possible with pessimist for the API says mother or not you check in my throat and does it there is something really bad it, but.

A

That's intermission, he didn't work. We have more nice rapport the contractor, so we can't believe the eyes that go in place, transformations right and.

R

A

Take one span: it makes it very clear in the signature what's going on, they just take one span, it's a read/write span and they taken.

A

Much data there is in the span, because if the transformation is expanding, it can expand to the whole span. So I don't know if we want to go like they Pia's get more and more difficult to to.

S

Us, maybe a party boy.

U

In brown, maybe.

I

U

I

Added in the future, run if first name or- and that was not saying that this has another decided I can like I- can see, use cases for to lower in place to operations, but those are removed by the way uh some amount up to that example. Last week, I think the German SME refer are we sure the two lowers who offer will always preserve the number of Arthur's numbering? Yes? Yes, that's one on Tiger, two dresses: okay,.

N

Yeah remover deserves the same number of characters across over all cultures, developed an ordinal culture of warning.

R

Okay, that makes.

N

Yeah I mean we don't support that the casings, that it changes a character length, so so yeah I mean it's existing. The Unicode standard like.

AA

That's a good xsi.

N

AA

I

Cases we don't, which is all that's because about what I just do on my fingers. I iced up the culture to the de de I have to capital a systematic call to lower and I got two more contestants, rather.

Q

I

That's a character, so that's a yes.

Q

They don't know which way it's what's approaching. Is it because only we had a German language expert, yeah.

AA

O

O

Expand which then, how do you fit there uh straight or super checked out I do the other way.

D

So, okay, let's just go with this top to bottom, so we can't finally decide what to do. Is the trim ones? There was no feedback I. We just take it out. This is whitespace going fine, but I have a suggestion.

I

Can we call it is void space or empty.

O

The reason being does it return true or false? If you have something up to you truth, because that's what isn't a lot.

AA

O

Does forestry is.

D

It it's a thing empty.

O

Or what space, what.

D

About now, isn't it is it all right, based.

O

On strength necessary, isn't that all whites website it returns true or inept? You want to.

G

Yeah, shall we have to think it's not. Alright. You don't think there's interior there's.

AB

G

Empty and then there's something or white space which.

I

We can't have bolt it would be, as is if there was this, but I am pumped that.

D

G

It confuses people that there is no erases uncle.

AB

Christian are gonna, show, trim puffed every trim you want does the same spent yes. Well, it's at IKEA, lab or slice trim.

G

Trim end is just slice, trims start is forward or trim. End is slice with a smaller length. Trim start is forward slice and trim as both right. It's.

A

Search and thin slice, but.

G

You're definitely just getting a like it's the same. Remember you just range.

M

Alright, so the string is norepi. Where is normal weight squeeze it doesn't have anything about is empty in my tree, like that.

D

So I don't either either way. Well, the argument was I think you said: that's right, there's no such thing. That's not here. Therefore,.

A

It should be, maybe is just right.

G

Guys, white choice is null or whitespace return is true for empty in the null or for span would be then this white space, where empty is defined by the other vendor to be white cells, so is white. Space is fine. Okay, it returns. True, you know.

I

AA

For any move, we.

O

Don't need a hood on white space, nautical for imagination or the analysis I.

H

Feel like it, it's the again it's. This is the span on a return to let's, let's call it is not white space. It's not that one. It's not not white space.

A

Does not contain non white space and.

D

Not not is not.

A

White space, okay,.

J

The only problem with this into your white I said little holes in the question, but I got wings and there's no white space does something different on it. So, just as ambiguity worried right all right so.

O

Then remove reset its try, remove. No, it was just a void, it throws a adjust.

AA

Anything in German, okay, void, remove you.

K

Don't see what you're typing and.

D

While I'm typing it here, because my life is easier, I can't look forward and then replace same thing. Replace.

O

There's the return options; instead, we have enough at this level really Oh. Actually, that's a good point.

O

Don't right! Oh no!.

B

Q

I mean like what, where to be good, because extra memory on.

O

It sure did some framework API.

AA

O

No, we didn't have finish or obvious Addison. Not now we had an issue that even probably talked about that. Maybe added applause, so we may suggested is.

D

Predicated on whether any other API is needed, yeah and then we had broccoli, which we used it and in later and then yeah and so like I, think if we ever need it, don't we just push.

O

It down just said: we haven't pushed it down holding because nobody ended up being a good thing, so this one's a big candidate for needing operation status, however well I mean it has. It is enough.

D

I'm fine with that.

A

I would be void right, so I actually went going back to replace I disagree.

A

Is one error condition? Okay, so if the destination is too small right and also if, at the end of the first buffer, you detect the old value, but not all one need to ask for more input, because you don't know whether you replace it on you know what I.

B

A

B

A

Let's say the old value is a B and you at the end of the span, and you see an a destination is not too.

O

Small, you need more data, but there's no condition this compares that version versus VD hasn't it well, that's it and you don't worry.

G

If this class, if you get the, is needs more source data- and you know you're at the end, then you're like well. That means it wasn't the match. Yeah exactly okay,.

L

D

Domain knowledge all right, so we have fine sent with those signatures.

L

D

Right now, let's talk about equals and compare any concern with those ApS. Is there.

E

A

Is there another replace? Is it.

O

That extreme professor, oh.

A

O

A

O

The overload yeah okay, so what is what is you ask? Why is there another replace? Oh I, never really.

M

It's just a clever why these are three separate is because the culture comparing youthspan overloads this or this.

M

What do you each other separate? These are separate they're not in, though, because this in.

P

Order to have any wonderment.

A

M

Need to compare the culture compared for the harsh manner.

A

But now we just decided we're going to have them all in all places, because we will correct. We will basically have three cold paths in there in the kind of you know. If it doesn't run on car CLR, it will try to get span out of this, I mean try to get the string out of this one and then call the existing api's or it will just copy basic power source that to string or whatever, there's stinking.

O

Should pay about this online yeah.

A

Create basically a string from the source destination and just how they.

M

A

Be able to check while another string has been attached to the string, it has access to the field, the object field inside span and it will just say, is it a string.

I

Oh, maybe not maybe, on a racism you can.

I

How does this work if you're calling an extension method on standard chart, or these hit like what these actually show up on Spanish ah yeah, specifically.

A

Specifically because I did all I see what you're saying no, no.

A

Easy to do sometimes read-only span and span, but I think for these.

A

Of we'll be relatively rare and then the the thing you can do is just say as any doughnuts bad.

I

Code, easy as I was thinking back to the scenario that you have earlier, where you're doing about your transforms one after the other, so you have your source and your destination and then your destination becomes your source for the next country, which means that that's actually stand up to you. Instead, yeah.

A

But you can do you know as renown Lisbon I mean, of course it's you have to know to do it, so maybe we want to add it I'm not saying we shouldn't, add it, but I don't know if it's worth it it's but like. We would have to basically double the number of methods here. What's due to becomes a problem.

O

Right then, and so the other Clopper ones, maybe they can be what is but I was it worth the same? It seems like the last one is essentially what crystal mention is very place that takes bull our returns both and takes it into battle. What do you want to do with that? We.

A

Also measure up versus as we can, because that will be what we did. The only thing is that, okay, so this one is a bit more tricky because chief, he gets this string and.

A

Then calls the string operation.

A

He cannot store the state for later. This may be tricky to implement, but probably it's doable. You know what I mean like this API promises that it like do as much progress as it.

O

Tell you I'm done here and then you can call it again so that.

A

It will continue last two.

O

Sets characters is a B and you're looking for ABC, it was not look, replace it and we'll say, give me more data. Maybe there's a CN there. You can always return bytes of it I do they already owe basic.

D

Just say always: we start like there is. No continuation in the debuff is big enough for the output string or it's not, in which case you always start over. It will not be efficient and.

A

You should always.

D

A

In the worst case, you can do really inefficient commentation.

D

A

D

A

A massive output buffer call, always okay, the.

O

R

A

Make you know how.

R

O

Try to implement it a bit better than email such as no, because the part that is, but if you don't know the source is over and you do it and does nothing SS know enough source, you redo it again.

O

The return is kind of source and redo the whole thing again. If it's the purpose right.

A

Wow well defeats the purpose, if you in the world, where you don't have access to the actual, yes, okay, sure.

I

Compared to versus compare since it is an extension method.

I

Should probably match the other instance methods or string mm-hm.

P

I

On string that says, compare the instance feathers compared to the static.

AA

D

You say that I buy that back. It seems not unheard.

L

N

Rich to know is like compare that kind of thing sense. Another string right and that's. This is the current instance, because it says it statically in.

I

Well, it depends on really how we expect people to call it right if people are calling it passing it. Basically, this dot something I thought it's an instance. Even.

K

Though it's time I mean it's: where is index off by the way you have index I want to the.

A

Index of ordered its it.

D

Doesn't accept its finger.

A

D

It is all right how do I get index off with the sweetbreads.

D

Just the longer version of contains right.

A

So question you to it: what you want so.

A

Is it's all data is that the case is that the case string comparison know all these AP is if string comparison doesn't show in the signature or culture info. It's already done. Instead, oh so.

N

Which was a beautiful, it's culturally current culture, white folk accept the place.

N

And equals oh I.

A

See: okay now I understand your comment about adding the original surface right.

N

This is, why is a string is very confusing today, so if you say like it's one, equal two qualities to this is what, if you say this one, what equal is to this is dead all right, but if you say, compare x1 and is to this is cultural. So why is this.

A

So what why would we not do they're all ordinal unless specified.

N

What do you think about this? So by default, it's ordinal, unless you specify again about like you know, if somebody using a string today, they will be confused about two's incident. It is because I mean honestly what you just told me: I mean.

B

N

Has been a lot of times, they are using. This string give you ice, so they understand how it works today today, essentially, yes, they have to know.

D

I know I, think I. Think honestly, the way it happens, this people write code. The code works in the three cultures, they happen to care about, and that's it I, don't think they actually understand what the differences are. Now, if you already poured the code to span, there's a million things you can do wrong anyway, so my argument would be I would be more with Chris up and say for this API service I think they would be better to say, okay, this is our chance of faces and say you can get any behavior you want.

D

If you really want to get consistency before framework sure you pass in, you know, string comparison, current culture, for you know the comparisons if you really care center. Otherwise you don't a couple quick comments.

AC

First of all, there is a fix. This is suggested to give you culture of the time which is kind of a pain on some of them and, second of all, most people do culture ordinate what they care about is upper case if he solved upper case and lower case in a culturally. That's where the cultural awareness of the upper case and lower case, but that's why people use it. He believes ordinal when they don't want a you know they they that's, why he was worried and so there's um it's very better case.

N

Also time people complaining was a strain going missing that a fourth time in that compared and they got surprised out like like some unexpected result, which is linguistically true, but they don't expect this right, yeah, so I I agree I mean like still some people confuse, but if you.

AC

Want make it better make compared to an enum and not have them have to go. Look up what negative woman! Why not you know.

E

D

Know they're putting longer a team bunch rather plus one, we just say less than zero and higher than zero yeah.

S

A

Thing is that the you know compared to is a pattern in the framework and it always works the same way. So, yes, somebody needs to learn, learn it about the framework, but it always works the same way. We don't have compared to method that returns. Some.

A

Versus the string semantics of strings comparisons are all over the place you have to kind of like remember, and it's not super easy to remember and I'm, also with emo, so I've been working on this I've been working on, be CEO team for twenty years and I, don't know seriously I, don't know some I know many, but not all.

D

AC

Was that was I would have added extra stuff to replace.

D

AC

The one thing we.

D

Can do with the ones that take in news you can default them the nice thing of defaulting it is. You know what the default is, because the telogen intelligent at one point with overloads. Is you don't know if you omit the argument with what the value is? You know if to beat the dog so.

N

D

To the sense was telling you this is like basically.

N

D

In brackets, with what the default values would say, string comparison tall order, so we'll tell you that if you a minute, that's what it will use so.

AC

If you did that, instead of making a lack of it, be still legal but means something different, that's what I was going I, don't like that to say that if you allow it to be optional and then the default is different than it is in the non-spam version. That's when I think that you're, really confusing people, if you now require it and default, is something different. I think it's my default it to what you think is right. As long as it's going to be, there I think that would be okay.

R

Just : best code without rewriting that.

D

Means see, do I get that but like as soon as you get like bugs you start fussing around. They intellisense it.

N

His people argue that we have thoughts, not there right. I mean like I really I mean like only compared to string and say yeah, it's equal and say no, no way this right, so they think it's our buds and then in and it's really their.

V

Boats, not outputs I, don't know like.

D

Maybe I I mean only you know in USS. It's like the way I think about this. If something looks different on screen, then I'm obviously.

D

I give they they give the if the if the bites are.

V

Different and the answer is it's different I'm like what ordinal, but but there is other I mean, like you know, like.

N

If you have this one right in all right- and you have this one right- you have this two string, you look to this- are equal or not equal to you a clearly.

V

D

Clearly it's years, lugu sticky is but but that's something I think as developer. I would be like I'm I'm, more inclined to say if I want them to be like identical I understand, maybe there's some option after passing to make them at people like medieval assumption would be it gives it. If the memory is different, then I would expect them to be different. I think.

V

The reverse is works, but the.

D

V

D

You want right.

N

This is English right, but if you are in different, culture doesn't make any sense for stumble or tarnish or Germany's.

P

N

Very good example about wrecking our you like this and I like this right. This is not capital or in Latin. This is different for reporter.

N

They're surprised this.

V

Are equal well on the screen? It depends.

D

On what you want, the compression to do like I think I would be messy what I'm trying to get it. Is it there's like four choose and then there's like false fault right like where you know you expect it to be true, but it's.

V

Fall to expect it to be false, but it's true I didn't mean the so.

N

The question is: I agree with.

V

You I mean, like you know, if.

N

If I'm rewriting the string class from scratch, I would do what what crystal suggested about like an everything, is ordinal at your life and.

V

If you need me.

N

Linguistically you, you can just have overloads for this right. I would say that.

V

I

Require that's you're just required with.

AA

Water water require two trips required.

AC

To be scheduled, don't have a default and if the default only serves to confuse people, it's know.

D

How this'll so? Ok, let me tell you, I, think this one and the reason it's wrong is that's effective. What at ex-cop tried there? Won't you every single time it didn't pass in the culture. Guess what people do string comparison slightly different, a culture. You say that but like in the end, the problem, is you open up there, the intellisense on string, comparison, there's like six values and the thing we've seen is a busy set time and time again.

D

If you make people choose like the thing is on average, what's your chance that the person typing the code in makes it better decision than we do and on average I would say the answer is: usually they don't they just pick a random value at some point like I would say if we can make a default, that is better than a random choice. It's.

A

Probably better so I would agree with that, but I I also I I can see the point. Your point about this.

AC

You two're ardours, okay, what right is how could we have you.

A

See you see cold and it says string.

A

The next line and it's a span- but you don't know it's just a variable name and course contains write and they look to you exactly the same and take a very different semantics. I. First there's something good about it. So, but.

D

I mean I, guess the other thing I try to get it, which I think I'm not doing the job of it's like take, for example, the the semantics we have with all the parts numbers in the primer, whether you pass in the culture right so unfortunately made the choice that the default is foreign culture or to string same thing is the default of the current culture. So there's two kinds of bucks you can have based on the default right. If the default is that say, invariant or ordinal or whatever the worst part you can have.

D

Is the things look shady on the screen versus? If the default is current culture and the worst bug you have is you cannot read the data that you have written earlier, so your data, corruption and the output is essentially just an artifact, a good.

I

Thought that was originally.

D

Used to make them table tops yes, no.

I

That that is basically what it is. You are, in general terms with X, because.

O

It's same thing.

D

Happens it again across the wire and that's why I'm saying like if you choose a default like that you they should choose the kind of box you can have and I think it's is it.

D

Then. If things don't look right on screen or consumers on the look at output, they don't think the output makes sense. But if you return, for example, two things or two strings are considered equal when they do not have that entacle bytes, it's the same kind of boggle sidewall. They should have been equal, but we said they're not I, think there's a kind of bug then Oh to do two different bytes return. True because it may you know school, your caching or whatever else you do when you actually make assumptions about that I. Don't.

AC

D

Your kind of bug and I think that is I.

AC

Don't I don't buy that buy that there's an ability to say that a bug that returns true and it should return false is worse than a bug that returns false when it should return. True, you have absolutely no idea what logic happens next and I think that's just I guess both.

D

Oh, it's not just to a fault, but the argument is that you basically make a decision on the contents of the buffer and if the buffer literally has the same bytes, then clearly it will be true or false. In position.

P

D

But if the buffer has different bytes, then the question is: if you return true, is this say UN my is better over us. So.

AC

You have a scenario where well, there are clearly scenarios where it would be better to have the default to be ordinal and say that there that they have to be exactly match that you and I could come up, particularly you I focused scenarios where it would be absolutely this is your point. You're thinking you I, you think what the user sees. The user goes with the heck. Do you talking about that? Those things aren't saying in fact, they're coming out even looking the same on my screen, I can't tell the difference. I'm absolutely broken.

AC

If you make an assumption that it should be or not you're, not I'm, going to say we had do not have the capacity to say that bugs that are because something says it's true and it's false are worse than folks. That say expose which should be true by the programmers intent, and so that's why I broke.

Y

So Leslie we have to.

AC

Require it because it's a freaking mess out there, it is any default. We do will be misunderstood some of the time by some programmers and if they do what you must suggest, they're just going to picked up one and intellisense it'll be on screen in their face. When they're looking at it, it's going to actually be in their code. It's not going to be a default. They have to look at. So what about.

A

AC

A

They have to say so: let's, let's start can we start with? You explicitly have to always specify and.

A

A bit more advanced developers who look for performance and correctness and then, if we kind of discovered that people don't like the situation, we can always add that involved right. But at that time maybe they will already like people who use the ID ice will learn. Maybe we will do it in five years and the default, and by that time everybody will know that you know well. I was just very different than today yeah. What I would say like we don't know.

R

A

Would be different because there wouldn't be contains that just takes fun and Polly. You have to always pass string comparisons, that's right, but after five years what will happen now? Lady Raquel data store not.

AC

A

Will just because you know.

AC

It is a preview wait for charging. Is that gallery they won't know, and maybe, if they yell. The answer is that that that doesn't ever even exist.

D

Main people already yelled today, I mean like I mean this is like super popular thing that hands him a push at some point to say you know, string equals and there was a few others, but I said I don't want to pass in the thing at the end, because it's a lot of text like people yell at us for that already today. So I'm I, don't think like five years longer, will give us any more insight at the last twenty years haven't given us or 15 years realistically, because Polly previously public, um but.

V

Me maybe you have would have like another guy to configure this. My default, like dress.

P

Does carry more action where.

V

V

Course the default can do.

D

Auction culture in the force fun is.

E

What you're healthier when you're poor sit.

I

D

So my other question is so, let's say, possum Tasha. All the time like like is everything that is culture sensitive or ordinal, sensitive, already marked no so too low I understand.

AC

I did not say past culture in all the time I said.

A

Passing string comparison yeah, like the comparisons I mean we have full already so for comparisons. We almost have it except it's not in replace unless I don't see.

O

The last parameter is why the bar, we'll both of the partial, doesn't yeah. That's always.

P

Because this one is, it.

O

This one has single person, but.

A

We have another: oh yes,.

S

So should we basically.

A

Just not have overloads that you know, don't take basically remove the first method. The first replace just have the second one. You always have to pass the comparison so.

I

Are you looking at the very top the story? Yes, it's just that group. Oh sorry, sorry, okay, I thought you were talking about over answer.

A

Like I mean it's, basically, this one has implied or banal right.

D

Which is what string, maybe.

A

D

Title I'm fine I mean like, quite frankly, it's ready to replace EAP on it's, not the one that will be a one-liner to call regardless. So, okay.

A

Adding one more value.

D

Will not change the API drastically.

A

So the only the only ones that cover implicit culture are the two lower in twelve.

D

That would be true that Walter wouldn't be string comparison right. There will be worse. Yes,.

A

That's cartoon.

A

But the default today, it's invalid culture. Is it invariant on current parent, couch and well, which is to be feather. They have.

AC

A

S

N

Di name as world open on it and it took the exact lesson at that time. I'm calling sold and I mean like to know the blissful so.

AC

It's you're saying something like let's just do contains, because maybe replaceable mark detains and possibly contains culture contains ordinal and notes note playing contains or.

N

I mean I contain contain ordinate, so this is vodka soda contains without ordinal. It would be like current culture. I would.

O

See that if for your.

N

AB

E

O

Mean providing a default value, pushing a person as orgrim. This is a few less characters if you're counting characters, Oh.

AC

One case is there a Tulsans choice when they pick the method and the other when they get out to the end they're, faced with a choice, those kinds of differences, so they're subtle, but they're I think there is a little bit of experiential difference. So.

N

If we have ordinance a method name to be very explicit and we were going to have to best extra parameters so.

I

We would you if you did have compare, contains more goals. You still have like a big mortgage yeah. We can advances, we can have it over kind of.

N

Another order is an hour you guys that.

I

Are ordinal specific.

A

So, like the string comparison, it's not such a big deal once you start going to like ignoring case, and this and this like it's an enum, it just say, string cumbersome that you know or do nothing no case.

I

Oh yeah, yeah I was talking specifically about the API so to work on ourselves, not being culture.

N

I'm just trying to sort by what like no one before, should we have and in same time we will don't have to specify a lot of stuff while callings I get so.

A

I would say, like you know, people who don't understand it. They just want default for a very complicated space where they should care, they don't care, they should just use string idea, it's like. If you hear you like. How did you get this pan of char? You probably thought jeez I want none allocations. I'm, like you know, this is a bit of more sophisticated software, the same developers who care that deeply about birth. They care about correctness, probably a bit more as well, and they want to be explicit about what's happening, not like I.

A

You know like cauliflower,.

N

A

Wonder what happens, let me think I.

N

Was agree about like we will care about performance? Would care about correctness is two different things. I can't care about performance about, would.

AC

You agree that they're thinking a little more deeply about their code. They're they're, not they're, not just trying to get down the fastest thing that does the job they're truck. They are thinking more deeply about code in general, and so this small annoyance of picking an extra thing. If it's not the person who's like doing that, you know, but if the person who's actually thinking, what is my code doing? How is it doing it?

AC

Is it as fast as it can be or I have a performance problem and I agree with you: they're not necessarily focused on correctness, but do you think they focus more deeply on the code and you would probably make the road extension rapid around.

I

O

Off should be at our value, the really spent charm but know that I need you looking for should be single.

O

It can be, has others called index of any as done looking for the string and looking for the substring where that starts, there's.

AC

Two there's a couple of overloads, one of which does require just a single chart, but then this replaces the string and does everything it's possible. People complain and ask for and overload that they don't have to have a span. They can just pass the kick to char in which is what they do for one of the overloads right now they might ask for that. So so.

A

Sit the culture here to lower to upper. What do people think I would.

A

Basically, the ones that don't take culture missions are not a caricature, I'd, be fine with that, and then you know like. If people complain about it, we can add them, but now we can.

O

That is, why do we need to know a minute as well? You call this passing by. It is a convenience method. It exists on string as well right, so does the other one without the attribute cleaver the pool or yes,.

AC

But but we bet it's a bad practice to use it, it's a bad practice to use it. So you know: let's go beautiful than that joke in very no. No. Those are great. No, the one. We got rid of I think this bad practice. Ok bar without a culture.

O

But cool or invariant is a good new to be passing in a very culture, but you can be fair.

AC

If you do it that way, you can you know, but.

D

They don't think it's not a surprise, more culture connected because it's better if.

AC

It wasn't on stringer, wouldn't at it, I think.

T

Right, mother to.

Y

Leave it yeah okay. So this is the a tuition.

M

The removes you upper the replaces up top.

I

Yeah, so on this replace it, we documented, where the possible return values of operation steps are because things like it validated.

I

Well, because operation status has several values on the right, some of which might not be affordable.

A

What, if you have an unpaid surrogate.

I

Data hope, if you have an unimpaired surrogate, then it just doesn't match or.

A

It's invalid data. No, what.

S

Does it kind of string ATS do no.

A

It's just they ignore and the circuits ah interesting yeah there's.

I

Otherwise, correctness well otherwise replace will always always always refer, not enough input data, because how do you, how does the developer ever say like there is no more data? After this, you have a boolean and the data flag, I'm, not sure kinda said what. So, how do you know that, like the source side passing it to, you isn't some is part of like you know the collected works of Jason it could be, but like it would be silly to assume that so we would never return, for instance, on the compiler.

A

Team at issue of what some people return: Andy, nothing good, I'll, tell you what yes, because let's say you you, your old value is a a B and you pass a source that ends with a we say: nothing up, data.

I

What if my old value is a and my source ends with be, but the next character of the real source would have been a because I passing. And if this.

N

Is easy for ordinate, as you are seeing, but for linguistic? Is you.

N

It if you don't like your restrained end of this, a musician, yes you'll say not enough data. If.

A

You find an A at the end, yeah.

A

Maybe I don't know if it's easy to implement so.

AA

Yes, gently be complicated, but yeah. You.

A

Are very smart.

I

That seems, it seems dangerous if we're referring something.

I

Then I say that's dangerous is because imagine a developer, who is going to replace a larger source with a smaller replacement, so he allocates his destination to be the same size as the actual incoming data, so he noticed that it's never going to fail now. He just calls replace without checking the return value, because why would it return anything under the dock? Well,.

A

So we should maybe we should talk about this offline because we spent so much time on this. The other alternative is just not correct, so you feed basically chunks of spans into our pipe, and it will give you incorrect data if you want to replace a B but a BS in one span and B's in the other yeah. This is life. This is basic.

P

A

The moment we return operation status, who kind of imply that the API can be used within a 5.

I

Minutes of wrong return, 5 all.

A

Right, that's what I'm saying it's I, don't think we can return operation status and not return. I need more data when a is found at the end, but I'm searching for a B, because it will be basically incorrect code. If you run it through the piper. Do you agree? Yes, no, no I never saw this is Python as I saw this, then their shows in return into.

N

Operation so then.

R

I go back to bull.

N

And drive less so sure what about to return the last found replaced, substrate or Socrates I mean, like you know, if you search you such a small string in biggest ring, so you replace, replace, replace and as end you, you just release Turtles.

A

Was that about like? No, we stopped here, plus that's exactly what the API is. That I was the semantics concept tool, because there is a Corral yeah. There are put parameters right, so it will basically consume up to the last a and it will say this is how much in consumed I cannot make a decision about.

A

The last rest, I need more data, and if you have more data, you stitch it using like a stack allocated span and then you pass more data in it can say that whether it was a and B or it was a and C, and so.

G

A

We don't want the API to go to basically be used in and with a very usable routine. That does the stitching. So if we don't want the API to be used in this routine, it should be returned operation service, because basically people will just use it and it would be not correct and it will be not correct. Only like weird edge cases when a and B are at their. You know at the boundary between two different spans, but.

O

That operator just also need to add the parameter consumed by Suncheon correct base. We don't hurt yeah, so I'm.

A

Fine with going back to boolean and basically just saying this is an API, you have to have the whole, you know this, it doesn't work with chunked spans, it has to be the whole span and the destination has to be large enough for the replacement work. If it doesn't, then we return false, but will still returns must found.

S

R

N

R

Which is okay,.

N

O

Emo, the consensus was the date. Sweeney may try to place and return both instead of operation. Charles have us a whole know how many how watering middle solution needs to be. They.

A

Try and if it fails, they make it larger and tried it. You.

O

A

O

A Caganer upper bound, you have an upper bound where you it's based on social and divided by the old vanillin, so you can have an upper body. You know for sure you some succeed. Yeah we could be talking about.

N

Which, realistically is not going to happen, but how? How do you know that to order 10 I mean like if there is no enough buffer, but you requests some of sub-strings, you return for short or.

A

If there's not know that, if we, if we don't return operation status, this API, oh.

N

A

That you can continue after it I.

N

Understand I mean, like our our your suggestion, is to return for you right. So if you could replace okay, unwritten poly and you replaced some substring and the fund at the end, oh I don't have to obtain for solos.

I

D theta 3 transpose, has also returned in the out parameter. How many, how large the destination needs to be for to succeed? No, the desert Menace was the out parameter, has known.

O

Health, but then how do we expected Homer to ever do the right? Now you go to government and.

I

If that doesn't succeed, you throw it again well.

A

So the only other alternative we had is Operation saddles. It allows you to continue, but then it has to have the semantics that I described, which may be difficult to implement and I think it's doable to implement it, but it may be not worth it I.

A

Would it's like two weeks of work, I kind of guesstimate to do the gymnastic, especially for rural culture, really.

I

Really don't want pipelining api's here, though, because this is for people who are used to working with fully self-contained data like sharing.

AC

I'm naive on this stuff, so my naive question.

AC

Contains because.

A

Contains there's no like there's no destination path or mutation, so replace basically mutates. It needs a destination battery if the destination buffer is not the right size. There's all this complexity, yeah.

AC

I

But in theory, if you were using operational status, contains, could still return potentially need to intervene.

I

Okay, if you're doing like a training pipeline, correct I would really recommend, leaving the signature of try, replace but having the out parameter returned the actual number characters of women, otherwise,.

E

I, don't think the colors.

I

Ever going to do anything, I.

O

Mean they're that point we're talking like wimpy region song with the eyes, but mostly ideas on false, do not give any useful information from down parameters and.

A

Also, the method would have to continue like. Let's say you pass a you know, input bathroom.

H

Ten bytes, we won't have to walk the whole moocher going to have to do anyway. If the operation would have.

I

Succeeded and presumably the caller wouldn't have culture if he didn't want to succeed. Amazing.

A

Measure API yeah, but.

AA

Now we get both boys one for the measuring and then must know so what you do is you you optimistically.

I

Alton, then you keep walking by to the actual calculation and that's all the power. This is how much it actually is good. Now having optimistically forgave you the right size buffer, you just do too much on this also means that you're destroying the Alpha buffer. Even if you've returned us so.

N

I would stand up. This means that you will really really are going to look at some buffers to do the rest of the operation.

I

Turns out, stringer is already does out there.

I

If I mean yes I'm, you can't get away, so you need. You need to keep track of how many different items you've seen like where all of those indexes line up, which means that you actually have a separate allocation under the covers string. Don't replace today already has a separate allocation separate from the actual output string. That's okay and the reason that it has that allocation is to keep traffic. Weird sync data, the spam, don't replace method would need the same.

I

Behavior I mean it has some optimization saying if I see like fewer than X number of things needing replacement, I can do a stack outlook, otherwise I still over to the knee like you can do stuff like that, but you can't avoid it entirely. So.

D

A

D

Then, from the API shame I.

A

Just think that if we start doing what you said, we need to invent new method, name signature. It's a new pattern. Basically I will try api's either work or they fail. They don't like. Oh, let me try to work. If I cannot work, then I will do something different right. Like.

H

The measure would pretend.

A

H

I

What we really need to see them with try replace, is an example of how a power is supposed to user.

A

Like I think this one would be used like as the signature is today, it will be used for short strings like I. Have you know like 20 characters and I know that I will be replacing a B with a so it's going to shrink so I'm gonna just allocate destination that is basically the same length as their source and I'm going to call it and not done anything more sophisticated I think we need to like specifically design the API and make it I'd line, makes you.

I

Know any measurable difference for information I.

A

Don't know we don't have any throwing IP ice here. You're.

I

Saying that, logically, it's the same, is that not a pimple on wall lower, lower invariant, throw if the destination is too small like we have? The API is a pro because they expect that the colors custom a properly sized.

H

Element sure, but do you kind of know what the size should be because of that? What is it yeah.

I

But replace is the same if you just said that the typical use cases you're replacing longer-dated tornado question no.

A

AC

Sure, where else was that there are cultural, two buffers and to lowers that will result in a different number of bites at the end. Okay, I didn't think so. I just wanted.

A

So I think we need more sophisticated baby eyes, but I would do it as a separate.

Y

A

B

So you try with my son.

A

He would we could I would.

AC

So why use so if, in your view, try replace it I do see it, throwing if it's too small or juice it returning false I will.

A

Return false and the reason for I kind of you know the other AP is it's nonsensical to call to lower as a smaller bubble this one? Yes, the mainland scenario is what I discarded it will not grow, but there are some other scenarios like we have many API scene already in the framework where they deal with small buffers. So what they do is they attempt to do the operation and if it they cannot complete, they return false and then you just double up the buffer size and it will succeed next time.

A

So this is shortly I.

AC

Should have questioned worries okay, so I have I, have I have two scenarios, one scenario I've, given you two smaller buffer and the other scenario is that the strings not found is, is try replace you're supposed to be I, found it and replaced it? Is that what that boolean normal? It's.

N

Just about the size of the destination right, so eight or ten inputs only if this is not enough.

I

Right this is only or so you just said you expect the color if he sees false to double the size of the destination. Try again is that guaranteed to succeed here.

A

What is specifically, you mean when you call it second time: yeah, no, you then double again and it's in perpetuity sure it's going to end up very quickly. It's a exponential function, I.

I

Didn't think we should be in the habit of having our callers make exponential of security at all like we should really be in the habit of hitting our callers used to doing exponential data based on potentially untrusted user. Oh.

D

But I don't understand how that how you could possibly solve the problem like the like the caller, cannot possibly know about doing the algorithm or for plays with the exact size of the buffer has to be yeah. It always has to.

AC

Be some sort of you.

U

AC

You pull that out and you don't have that at all and what you're getting is that if the span is too small, the destination is too small, then they're going to wind up with an exception which is going to hurt their performance and because tire design is not to hurt their performance to Purvis you this this exists, so that it is that's why this exists right, but we can't get enough information that that's it. Sir. No.

I

AC

Our place in strength, no shells right realize.

I

It's not complicated enough. The reason it's just regular places to go sale right. You can always allocate it out from.

AC

Don't replace make sense to have nothing I'm saying, try, replace, doesn't seem like it's giving you much the confusion and like I, said, I read it wrong. Nothing think it was doing what it's doing and so I feel, like maybe I'm the only one in the planet that will ever look at that and have the expectation that I had. That was completely wrong. It is possible. It's.

A

A good book because we.

AC

A

I think I would pull.

AC

It tell you, have an API that sufficiently complicated.

AC

For example, with a tuple or, for example, with something else, and maybe if you have an exception, thrown at least time up.

AC

It's a receiver will Graham question.

N

About bytes written this is the number of bytes it into the output right. Yes,.

A

And also another target gene charts, yeah.

N

I understand, but why we don't give the hand also to return about where we replaces a lot string in the in the source string sources.

N

Mister for that location, as you mentioned about, like you know, if I have like 13 characters and I best like 5 character, destination and Richard, like you know, saving characters, it fits in five. So I know that I don't have to allocate another five. If, if I, the remaining is just.

N

Maybe the Chris office described it's not five lines, but it's just a hint about like know where how far I want to the source and replace strings it yeah that sounds exactly.

I

Like the pipeline API, because in the case that you're describing you want to be able to do partial data and then the next time you call this method just pass in like a different window of the input string at a different output buffer and then you'll just manual stitch them all. Look at me up right right.

A

This is what I'm seeing adding this will not as complicated. So so what about this? We kind of ran out of time. What, if we just remove it and basically this one method and try to design it and add it later, because it seems like you know, it would be good to support the pipeline scenarios. Maybe have some measure api's for some other things, and it's not like you know, replace, is critical to be. Anybody opposes to this plan. Wes is.

W

N

By night was.

D

Original, replace you mean ain't it to private players, brothers, as this as soon.

AC

As no replacement does not replace no, it's.

A

Just not really place that we place it does with.

T

T

A

Jesus spent total like two hours, so nothing.

M

Or like we don't other two hours for this review, no.

A

That one was altitude.

D

One you know that what was the one hour, why also T's? No, so we're done so. The other two things were not ready for view anyway. So it's good all.

A

Right guys, oh my my.
