A

That's in the past to Paris the real problem is: are you before or after the the week that doesn't exist due to the gregarious.

B

A

Bright is it before, after the switch in Russia or not Russia, all.

C

A

Whose order you want to go.

D

Through Carol remember,.

A

D

Do we have the right people like we have the you know, WCF folks, for the service model, syndication thing they want it. We don't have them on Coliseum. For one thing we want at the arm and Jeremy Kuhn has two of the five I/o. So you know necesita of notes, I assume it said.

E

The father wanted skater because it's gonna put triage anyway and then that WCF, the other one yes Sato, that that would I would do the other ones that are like. Basically.

F

In the I, don't have do.

G

You want me to paint going researched yeah. We can actually bring him in. That might be all just sort of know where Bo is the unthinking, unique good fairies.

B

Ministers are one rich.

G

And take five minutes off you already you're, already further! Okay! Keep in here long enough that that's.

H

E

Just pick a random obvious in order to it.

I

All right so each person, yeah, okay,.

J

So the proposal here is just we want to get it. A X opposed get unicode category, which is take a safety 32-bit instead of one character string.

J

So today we have a way to do that in two steps which is converted to this.

J

Then we good category format, but the problem of this is obviously we are creating extra string pieces. So the proposal here is just have one API that doesn't allocate any strings and the return the desired desired results. So it takes an int correct and take an entered as a decade.

C

So unicode scalars are unsigned in its correct. Do we care about the range that the int method would not.

J

Cover so I, don't think so, because the range is now it's. It's like the 16f.

K

J

C

J

24 that's right now the maximum value will not. We.

L

Never gonna have you want before they need.

A

L

Labelmates double you know, 30 is.

A

60 thousand planes they need a double unicode. I think, seven more times before the site is okay, so we could. We can have this method just throw a few passing our right hand and.

C

Also so scalars are subsets of all Unicode code points. Are we gonna throw if you pass something? That is a code point, but not this error? You.

A

Mean like to pass on a surrogate is: this: is.

L

I think that is a category.

A

I'm pretty sure a Unicode surrogate is actually some category. The category is surrogate no.

J

No, no I mean okay, so that the circuit is two characters right. If you miss just one character, it would be surrogate yes, but if you best two of them it would be another yes right I'm. So this is this one, which is the.

C

The post together, which is give user where I'm not talking about like.

C

Is that surrogate character is not a scalar.

I

C

This ABI should, if it accepts surrogate characters, should not be called get Unicode category from the scalar, but rather from Unicode code, but I.

K

C

Your name is: there's no bids in the parameter anything I'm going to do. Okay, if you, if.

J

You have UTF, what's.

C

J

Parameter name.

C

Cah, oh that's. We also need to talk about that. The title of the look at the title of this pull request I mean this issue. It says Unicode scalar, so I I was confronted. Yes, this is confusing. Okay,.

M

Forgive me we don't have a type of unit or any well I.

A

Got a proposal for.

M

C

Somebody was basically saying this would be the name of the parameter: no okay, okay, all right. So what's the name of the parameter should be Unicode code.

A

Points or confound it I mean.

N

It represents a code, whatever you want to call, it is okay, Amy and I would say. Ch1 would.

J

Still be okay but see etchings; okay, oh baby, yeah, we'll.

H

Do it cause the existing way? This is probably just seen.

A

I know it's probably char CH, but I'll tell you you can never go wrong without you. Let the suspect call a datum on utf-32. A code unit is a datum map. So should we call.

L

It code unit I think we should be decoded code point or scale and I'm gonna look now in this back. They say: if you want to accept d800, then you should call a couple points, but yeah.

A

Like values, thanks good and then you just talking about what it actually takes.

O

I'll be sure it should go quite high.

O

You like it I, like not you, okay, can.

J

You get the documentation for convert from utf-32, we can see what is the name of the angle there. So, let's see the word documentation, yeah, but we're in the.

P

Ramekin images, apparently mr. Emery,.

C

P

Least, yeah that wouldn't be that what.

A

Income is this God, the.

Q

Premise, the brand.

A

Name in that's utf-32, literally yeah, alright, so yeah.

O

Which is good, I mean I'm.

E

Under the existing method, you know gotta go, it takes two arguments string and an index, and the string is called s. Index is called index right, but the so I would argue that, given our string works, it's.

F

E

It's not yes, it is because guess what the existing method does it indexes into the string? Take that jar and runs whatever that thing there and the existing method doesn't work. No.

C

It does it just allocate; no, it doesn't work for anywhere about BMP, no.

J

No, no! No! What torkoal zeros with surrogacy yeah, what yeah yeah? Okay! So what it does! Is it it checks to see if the character that you've pointed to there's a high serving so what's this another convert from utf-32, it will give you a string of two characters. Yes,.

B

J

If you take this string and pass it to the get your category, it will take the two character and know it knows that yeah it's or gets so I can get work at.

Q

The next character, but what movie thanks demos saying there's a method that takes an index expression? That's where you started and that one is a lower, looks like next kicked all right. Oh okay,.

H

It jumps to the.

R

S

And then optionally.

C

Also read the next K okay, so in it. So it's is so it's not a character because it reads potentially either one or two characters. It.

J

Depends what you define character come.

C

On I define it as the type that we have in the framework system, dubbed jar. Okay,.

J

K

J

I agree with you, because this is why I I said I suggested not to have this. The I expose from charm struck and instead it from the other type that yeah.

F

Character, Unicode and by the way, our chart a business in labor, because it's basically YouTube sixteen Copeland right good unit, sorry code.

E

You that's, which one which one Chaco charter.

C

Therefore, this one is not jar, because it's not utf-16 code unit, it's two of those which basically has a name in unicode spec, it's code, but I should call kind. If we need to call it contacts, it should.

J

E

You just call it CNN could be the Co point or charge.

K

But you want to look the other way to fix. This would be to introduce pan overload for the getting code correct category atra. The only problem the existing API is. That typically requires you to allocate thing right. Baby.

K

R

A

That's already utf-32 and then you need to convert it to utf-16 to call the existing method. So now you, if you have utf-32 you, pass the utf-32 value. If you have utf-16 surrogates, you need to combine them or you can call the old thing in the WTF 16 on zurich, as you just added. Also, there may.

C

Be a small issue with endianness, if you and if it's a sequence of charts versus if it's an INT, there's no I mean endianness, is let's trick a little.

T

C

You have the right, it.

I

That it may be a penalty ass.

E

I

E

That's not like.

C

A straightforward primary: it's just maybe what you know like the suggestion that young head would be a bit simpler. If you already have the straight, if you already have a string getting an int for, for you know, the next count points. It's not usually.

J

The algorithm the channel will be very good if you already have the stream in utf-32 and you just use the span over it to do whatever. But if you have just one value of UT absurd to you, how do you get the value? That's my point.

C

Do we have an idea in the framework that says, give me that next cold part? So if it's, if it's a surrogate parent, it gives you yeah, we have X chars and my class is called the string and you have to use it correct.

J

And then you can get the int basically that we would have the ID I write it give you actually yeah. You can remember it over the string and if it is like surrogate, so it is kept by two. It is not serve it escaped, but you have to enumerate correct. You cannot just say in this location.

C

A

Considering a utf-16 string as and then you want to enumerate five scalars like because they're variable length encoded, you do have to go about my Colossus chemical.

E

Isn't the way it was on tempeh? This streaming looks like, except for the camera I.

A

Don't know if we have an optimism we have surrogates I know we have one for ask Erik, Hersman or not ASCII I.

G

U

G

An optimization there.

A

So what was the best proposal? We've been hearing just to call it code point as a primer, mm-hmm I.

D

Mean that is called the spec that lets.

L

Get bias bearson is correct for.

D

L

D

L

D

Does it relates to the proposal from Miguel about learning system Runa, slash corner? There have been long discussion around that as well.

A

A rune is not a good point, a rune is a scalar. They are two different concepts.

A

You said before the confidence that makes me think I've no idea what you're talking about, because.

E

A

Likes to define it differently and what I said is it does to my adversity. So you said that the spec says that a utf-32 datum they could unit is.

V

K

A

Could point to code unit that will need to care about? So yes, so a code. Well, a code unit is in imagine that you have a utf-8 string. Okay, you tfh string consists of a bunch of beauty if they integers all all sequence. Each of those utf-8 integers is a utf-8 code unit. A utf-16 string is a bunch of utf-16 integers called utf-16 code units, and you can do the same for utf-32 and so on. A code unit is not necessarily a scalar. It's not necessarily a good point.

A

Now you know, code unit is just how do you represent this as an integer like either in memory or on the wire code unit, is encoding.

A

Okay, the point is the this is unit: u plus 1 au courant sentiment so.

W

That I, like so.

E

There's a cool point: the only people would like think of as an individual character right.

A

No, a scalar is what people would think of as an individual. We are but hey and wait. Okay, because a scale, a scalar is a code point except for all of the surrogates. When, when I say, surrogates I mean the individual hi surrogate 16-bit integers and the individual Oh surrogate 16-bit, when you combine them, for instance, into a pile of poo emoji a little.

B

A

Emoji is a single scalar, also a single code point that consists of two utf-16 code units. Hopefully.

E

That made sense: are there any like they skaters the consist of multiple code points, so what the vision.

A

E

A code point in skin and then as.

A

I've said a code point is a superset scalars with the graphical overlay like go back one character and draw over top the previous thing. Oh like a modifiers. Basically like, though those are still individual code points, individual scalars, a scalar doesn't have to be a printable character. A scalar is literally have everything from 0 to 1 0 ffff, except for these surrogates, like da 0 0 for D F F. That's literally the only difference today, a close relative ASEAN.

E

It close enough tomato Chism, I, don't know like honestly like so we haven't overloaded. It's called gate, Unicode category that takes a char C, so I mean we can everyone that takes an envelope point or cursor code unit. Oh, come on good point: yeah! Okay! I can't wait! Ok like it!

E

It's just it in z+ code points good.

E

So the existing one that takes a chart. That means that that has correctness issues if you call it from the string correct, like I'm supposed to call the one that takes the string in an index rather than passing in the jazz record. So.

A

In particular, if chardot is, is surrogate of Z? Yes,.

C

And the class already exists correct cherry on the clan just additional member.

H

We need it the inverse of literal currently there's an get numeric value as well as soon as sort of the inverse. Interestingly enough, a returns, the devil.

J

Yes, the numeric value.

J

There is some some unicode characters that it has it's a digits. Oh so.

X

You want to get is I want.

J

To do it's, giving it's translating.

H

That can character.

X

To like a number going that way, I.

H

Assume it was getting that.

X

H

X

It that have I'm gonna tell you.

A

All right, yes, southerner birth, so there there are unicode characters, as in the the Arabic numerals 0 through 9, correct that we're all familiar with. There is also 0 like inscribed within a circle which presumably this API return, 0 like to inside right within a triangle or something and then like the fraction, 1/4 and 1/2.

E

Anything has it just that's it good. Okay, next.

G

E

G

One helper that one that's pretty good young, take.

I

For the rector delegates.

O

F

K

Big a did. The problem that is proposal trying to solve is that today, when people want to float, make the fly, beret and discovery dynamic that run time, and they don't know where it is or what what the exact name is on Windows. You know they just be involved. Growth, library and you know, get broke a dress on UNIX. You know, if you are kind of in the.

K

If you are just, are getting the main line, distrust you can tl library in similar way on Windows, but unfortunately, the dear library isn't like name they same way across all the UNIX system. So there's no good portable, a how you can really do it on Linux pixel, there's no fixed library to be invoke in do so. This the whole point of this propose is just create simple, manage wrap around those two there's, no safety I, so that you can begin to apply, break and rock address in whatever I see.

K

So it's basically when the names and only known that the run type.

C

K

C

K

The names or location site, for example, you want to probe for it in some.

C

Is not the problem or.

K

You want to have control over which versions you will bake right. Sometimes there are multiple versions of the library and you like one better than the other one night, so you can want to profile um so.

A

The problem that I raised with this class.

A

Kind of the last comment that this is all safe, looking code that then as a thing that results in undefined behavior for delegates that you've already Val, you know what it makes sense to help delegates capture the sound reco be like today.

K

This is in system and a diameter of services, namespace ID, so it's kind of unsafe, ID by convention right, ah you know, I, would today the problem with delegates to delegates pointing to if you get delegate from our manage point today right, you have the same problem already, so this is not trying to solve that problem and you know be in order to set say so that problem we would need.

K

It goes slower.

K

Like how to make a beam folks out, you know like calling on magical via delegates like safer.

M

And I say, like you, have a good simple today: it's basically when people do load library themselves and.

E

Then basically bind the delegate and later call was it called free library, I guess yeah then.

R

A

I the problem here is: if somebody makes one of these and something like FX, copper and analyzing, say: hey, you created a disposable thing. You should put a music statement now they put a new using statement, but they returned to delegate out of it. They're gonna crash right.

K

A

R

A

It needs to not be disposable where the delegates need to be safe, but that's another difference.

A

There's a disposable thing here and people go make this rules only by wrapping. It neatly what I've always done in practice. Every single time I've had to do something like this is I always end up calling JC handle Alec on the native library. That comes back because, although certainly my application is going to have incorrect behavior if I'm ever free, this library, I wonder if, like Jeremy actually really does have a point here is: do we expect the majority of applications to keep these things alive for them for the entirety of the app.

R

Probably, but you know, they're like by the cases value actually do.

K

One to unload a library so.

A

I'm going to agree, but.

W

A

Those ten percent fewer.

W

Maybe yeah that meant Oh.

C

So, let's go back to the FX capital, make sure that we are not putting people in this situation where they shoot themselves in the foot there. The rule just says that if you have a field that is AI disposable, your type needs to be a disposable. It doesn't inspect your code and tells you that you have to code this post.

A

I believe, if you call a method that returns my disposable and you don't do anything with it, such as setting it somewhere or return it back to your power I'm, pretty sure it says you should put this in a recent statement.

A

So you call native.

R

Library, open it, it returns my disposal, so the rules for this are.

K

Same as the rules for delegates you create ourselves for parenteral right you have to if you have to keep them alive right, but uh okay, I.

R

Manually call it both library, you.

A

Didn't like nothing that we did put that in a disposable type for you, so probably most people we're calling load library, never make a copy and book and a free library, and then it lives forever. Okay, so that's that.

F

T

Separate the I guess, rules were from the general API should.

E

They say they would not implement I, disposable and instead of having disposed, you would have I got an unsaved free or something right. This is a very aesthetic that shape then, or is it literally just ability.

A

That you can unload at all, that is the problem of being able to unload as useful, like I would have used this API kind of existed in. My previous role, like this looks immensely used. So if your point of view is just the fact that it's itis fold, which makes it slightly.

R

A

No, not necessarily that, like I I think it can be I disposable, but also safe. For.

R

Instance, by having delegates keep library rank, but that's kind of killing the performance.

K

Of internal pride and making more complex, I wouldn't want to do that, except, like you know, I, when you look at the inter up that how people use delegates for for, inter out, you wouldn't actually want to use that I. Guess II just use delegates picture, that's the only thing you can use in c-sharp right.

K

You would actually want the the interrupts to just do. Call I, and you know in manage the past paths. You could have done possible sobriety dead weight today, so we are using out. So if you want to make the kind of interrupts fit delegates to be more kind of bit of success in stuff failure, that's today I think we should be looking at that. You shouldn't be looking at like how to make the delegates. You know that are so already in slower, so that they do some light type like time that.

A

Obviously, is the argument that you're making that you think that would be an unnecessary performance for yeah? It's it's like.

R

Then could it perhaps be an offshore friend role enough yeah but I think if that's the case, it should be basic good.

K

We should be looking at like changing how to get delegate API to de box right. So the one thing about that is the get delegate. Api is just like it's fine to remove this from it from this proposal in the current proposal, all did get delegate. Does it just you know, cause the marshals get delegate for you so that right? ah So, if that API is problematic, we can just remove it from the API and people can do it themselves right. It kind of wouldn't.

R

Change anything, but then how are we having value other than there's just being a wrapper around like save library and yes, that that's that's kind of the key value of.

K

This API is proper. It's portable wrap around pull, I break. It broke address its.

C

Portability, whatever I.

K

C

Know get simple and you don't have to worry about. Different doors is.

A

There a thing we can do with a safe handle that if anybody calls get delegate the safe handles now tracked finalization independent of the lifetime of this thing, making it return, custom, delegate types to track the field or something so.

K

The delegates today super comp I all right and the other thing about hey. You want to make it even more complex by doing some extra tracking for enterprise as.

R

I think they go through this.

K

R

Would have the.

K

Safety that I, don't think you do I kind of disagree that you know like yeah. If you are using the interrupt ap outside you have like many different ways. How can like throughout right? You can have mismatching signatures right, you can go drunk method so and I think the key point for instead of, is you kind of want to invert. We fast right in the past.

K

We have like bolted bunch of stuff on to interrupt and then make everybody opt out of that, because if they want to interrupt to be to be fast right in the early days of dotnet, like the Interop was doing some, some crazy cast checks right, everybody was opting out of it weeks of and and this is being the same category right. You are talking about how you know in order to do to get delegate you want to check in on that part. So you know. Is this a life, and you know how.

A

Is that any different than house you in a safe handle across a period of boundary, because.

R

You're safe handles are like slow times. They do to interrupt operations because they do they do an a.

A

Dangerous address and a dangerous or no ground correct, yes, and we don't think that that performance is acceptable for that.

K

Performance is not acceptable, like you can ask like that, for a magenta made of working on system, IO, eBay.

K

In our own framework, we are getting rid of, and we are sized I think the same hand was the same thing in networking stack VP. We found this to be both might be become sites that the siphon sale handles there and we can't doing some other crazy thing I. The crazy thing we can do here for whatever reason, but it's like library dependent. It's like the the up stack code. Somehow you know and base or this- and it says out: okay I know I know, but the I'm doing.

E

Honestly think that comments in our sample I mean everything. Interrupts services is meant to be your building block this unsafe to be wet and cold. It makes this a so I think now I.

K

E

Make it possible it's those are my excel. This is not the term services itself provides to say by the assumption is that it forwards the burden to the constructors who use it as the Google and I think everything you know, I think the best case we can get it but like risk is in that's why people, maybe just of the check, twice exit easy. We just increment I, don't have a safe way of doing.

A

This then we're doing a disservice to our customers, because someone's going to post a minimal example on Stack Overflow that is going to be used in everything and it's going to be unsafe, with undefined behavior. No.

W

I, just group that I think I think we can. We can totally make.

E

The API externa Tory, in the sense that we just give it the right mix if we can already.

T

E

An unsafe sauce that does unsafe us, we, like code.

E

You know get delegate awesome name of invested in a committee specifically delegate as well. You already have in million ways you can misuse the API. This hose is just one I. Think to me. The only argument to be made is that, like you know, the name native library expose doesn't necessarily imply undefined behavior right I mean if you just rename the stuff to basically indicates you know, unsafe native or unsafe library.

K

Or something the basically I think that everything is in system antimatter of services. Namespace is implied to be unsafe, that's how we are naming the API side. For example, we moved the some of the unsafe API from spam to this namespace, so that right they account the.

A

The argument that we were making earlier was, if you follow the tools of you talking.

A

A dangerous I like.

R

They won't tell you to misuse the savior. That's some concern.

K

Okay, so I I think it's fine, for they say for this not to be I disposable, it's fine for this to be the method to not be called dispose, but call it three I or unload a time to not have to get delegate a convenience.

R

Method in there really, what all these things are: fine, yep delegate longer I mean for convenience as long as our tools are telling people.

A

Misusing API, okay, yeah.

R

Like really it's the it's.

A

The company it's the TI disposable in the fact that, whether it's our tools or recharge or something, okay, hey this is I disposable. You should put an easy.

R

A

The other thing.

E

Is we really have that understanding local context? You also entertain it you up, adding and unload, or it would make that a disposable either right, so in that sense, I, think, unload and disposable. You could argue and say.

K

Make it not I, disposable and claimed.

D

Disposed to unload turner has proposal to change it to unmanaged library versus Snyder's library, I. Think.

I

We reuse native in other areas as the prefix.

K

About to be used on mage, that's pretty big! Do it right? That's true!.

R

A

You, if you do have an unload or a free method, is it allowed to be parameterless, or do you have to be able to set parameters for playing? If you want.

A

Operating system where, when you're reading a library you have to pass in like the same flags that used oh I, don't.

A

Know I mean if you have to pass the same time you gave to open a bluish, a disorder actually flies, no I know of Windows. You don't have 200 I'm, trying to figure out if we can ever get into a situation where we now have to add a new on the ideal. No I mean like open.

G

You can something so current like we would have to add over all of Obamacare and added moment that in the world for unload or something or figuring out, this make sense right.

A

Oh, do you need an API on here to get the real path that was used for the DLL in case you.

K

Need, apparently, do.

A

K

In on UNIX in practical, you cannot go back from kind of you know, file back to file path and it's ambiguous because of links in title on labels. It's like do already have a deal in for.

J

Search box ready.

C

Which directories property do I assume.

H

As recharges default set such that you can catenate and reorder them, investment to open this da.

K

This is it if you want to search for divided at the same way as the runtime book, but you want to customize it mama area, and this.

C

Is the first place is because this API, like it's weird, that this API is on native library, given that it's a search part in general for the only other when a figure to speed run.

K

Time its search path, specific for 95, ready for its specific to native, like it's not for managed assemblies or something so so.

J

What what happened is I call like such personalities. I got the list of directories and pass it to open with customizing it and after that, I will call back search directories whatever get so. The.

K

J

K

This is a metabolites like its proper latest site. It always ends the same so.

R

K

R

J

Right because, like this would be confusing because, like after I called opens, customized directories, yeah I would expect like this one, which tell me the customized answer. I mean this is static rather than instead.

A

So would have to be a little sub, which implies it as a default, but the name is right confusing. Wouldn't you also mean.

C

By passage to open up and doesn't take care agreeable and extra little for church as well.

L

But that's not the return type of sales directory. So what why do you need, sir.

A

Short reason like what does it give the developer? Why would the developer ever call that progress? Then you.

Y

Want to end one more.

K

You will use two digit or something more, maybe.

D

K

So today, I'd people want to, uh for example, our example in the system, drawing something since the drawing come on.

K

The pass Enda is like you kind of want to use the OS library if it's there, otherwise use the one that was published with the opposite four-bike. The developers.

R

A

Building up the entire path himself owned by looking at the default search directories and then saying does default search directory sub-zero. My dll access, no does supple. I've got my dual existence. Oh, is that your idea yeah.

K

That, and do this like a spot of longer sequence, I first, look some badass then maybe do days. Then.

A

Then that also implies that I should be able to get the full path back from any arbitrary GL. That's open because I might need to know. I might need to load a sister DLL to that. Oh.

K

It's true that we can in for these API because, as the name, we can have a property that you know gives that name alive, and you just give it back to you. But.

A

It just strikes me as weird that what I asked earlier like is there any reason that you would need to know the full path of the particular zlo is loaded from the answer is no, but is there a particular reason that the application developer would need to manually create whole paths for particular DLLs? The answer is yes,.

A

If you want to know if.

E

A

A

Ended up loading. No, but if you say that you have a dll and B.

R

Dot, DL, L and a depends on V or a is a play about the you are loading both oh damn right yourself is.

K

Not kind of exchange type that will be in public. You know CHS of the light base right that you know not.

A

Necessarily so if say that say that you're loading a plugin, for instance right like you as an application developer like maybe maybe you go through the typical search directories manual, concatenation ant,.

A

R

Future DLLs relative to that guy, like you, could keep track and.

K

It's like that. That thing is different right. You have kind of plug in and bugging listen playing some directory and you kind of what I can happy I did code, so this API does isn't isn't other thing, that's an I/o! For that scenario. We have like another hook on us and low context that lets you load unmatch assets for safe, plugins right.

K

This is kind of when the library doesn't want to be kind of plug-in. It just wants to be kind of self-contained unit that you know way. I looked at the API sent up interrupt services namespace the anime seems to be more common graphics than native. So there's like a mesh memory. Access a mage memory seem mermaid function pointer, so the unmatched might be.

T

I don't have and.

B

T

Only thing I remember is that people divided native code generally don't like.

J

Yeah, okay, further open missile. If I pass not for BLM for search path, this will just use the default. Oh now, ITT now I'd say no! Yes, because I didn't know that idea. It's ethic for so.

C

Which option said like? Should I which options are valid for they know? Looking at.

K

The options and like the idea is that the API will do the same thing as if you have DL impart with name and deal import search path. It's exact same og.

K

The DLN port search part comes like a second attribute. You.

C

K

Specify the dll.

C

Import Saoirse should we currently default.

A

We're not the reason yellow import doesn't allows you to not specify. The argument is because dotnet framework b1 allowed you to not specify the argument, but it always pops up on people's security. Reviews of you need, somewhere to scope where this DLL imports coming from it's like. So the security guidelines say that you should always specify it, so we should make people always specify they can make their own well.

E

I mean surely I'm taking very conservative choice. Right I mean we don't have you that it's like.

C

Comes out about they've choice, it's kind of thinking well, application director is, is relatively conservative, correct or.

L

Semi directory is only both. It.

A

L

A

L

A

The options is correct: you need to know which of the options is correct in contacting, but that's other wouldn't have an option. If, although like every single one of the options in that enum.

R

Is wrong in some scenario, if.

K

You have domain photo, I, say PII, you can't really don't fund.

C

To get out so two valid options today, our assembly directory and oh there's, no a circuit. So what is legacy be here ah program.

S

All over the place did.

S

Someone go through it, it's all over the place.

C

Like us interesting save directories yeah.

A

Well because then, the human second on the one that's not painted or the one that doesn't take an option also can use a similar level attribute, which would then become weird with this and like who is assembly or addressing from so be. The guy who immediately called this function, but like was that the right answer was that yet another benefit, because that's never Fitness India's right. So I think that we want to leave it as a mandatory artist, and if somebody doesn't like that they can make their own function that calls this one.

A

It doesn't take jerkin.

E

Do we like this.

F

Bow and arrow, because I think we said before we don't want to API. Is that indicated for bluing with other floor? Not the reflection.

A

Api is held, this parameter.

F

I mean like they ship like a new one right, so there's nothing. You can do about them. So.

K

It's fine to not have to throw an error of the interest return now they would return now or we make it. Try open! Oh, and you know you kind of. If there is an error example.

K

Actually it would be kind of death only if it's not found in there just a bladder. It still grounded. Okay,.

A

So maybe we want to be try open and try get elegant stuff like that, w do if the dates not found.

C

Much like right now just returns wells because it has well. Oh, it has false, is the decode. It doesn't throw.

I

Returns in dollars equals so maybe make both maybe make a try open, tried it on it.

A

And to try get simple atmosphere, and so why don't we just throw by default? Because there are cases where you want to probe to see what capabilities into.

R

Your life house so then main menu, then.

K

You know what that is, Bozak see you can just use the existing dealer important. You don't need SAT at all and in most cases nowadays.

R

It's like not ten percent over yeah.

A

So like in the AC, don't a crypto stuff that I wrote a few years ago on one of the things that we do is we open be crypto tol and we test to see what methods exist, because otherwise we have to do an OS version check and it's just unreliable.

C

Yeah, in this case, I would I would make it try.

J

At node a document you have this pattern before to have try and then sometime you cancel from it, not.

C

J

H

C

We have no parent, where you can try again that's right. No.

H

It does there's lots of third try, AP has it through, but they only use.

H

K

Carbon one and it would be as it still the case here is it fails because of.

J

And send angular different sends our other condition like memory out of something, but but if I best like if I call I call it like dry open and at the same time, passing through on error is true. Doesn't.

N

Make electronic.

J

N

This parameter anymore, we're removing throw an error fog, there will be the shape, so will they keep the open.

G

C

To get be able to try or having have just to try, yes, I invited, try, forget simple address and get delegates, but Carlo has a good point like. Why did we change open to try open well.

A

It's very useful, but we read both it says, can be so on. You know to take Levi's example, where they open decrypt, if Windows XP was still an option that you would try to open decrypt, because it's not it's not they're. All on XP.

C

You can open and catch it's you doing it nonce at the beginning of your program. That's true! For really you mean mother. The.

S

Other essay of the guideline did you try something catch? Oh, it didn't exist. Well, the other one. The other one is like I assume is pretty fun performance.

K

Else not a bit more Gotama system.

S

K

Other ones are other ones. You also typically coachella funds in your program, forgiving X, then maybe this should repeat right. You mean I I,.

R

K

That needs to be away how to do this without exceptions I, it's just the.

A

Thing is especially with opening like failures are a bit weird, because it could be that the DLL exists, and it could be that you actually did try to open it, but maybe it's the wrong architecture. Maybe some of its dependencies are found, and so on. Should that return also? Should that grow exactly.

L

C

L

C

You get lots of information with.

L

Just happened if you want it well, in the case of low library, a job, fortunately, as far as holes, and we.

H

Can make the first 3/4 case only be whether that exists is existing right? That's happened. Everything else throws.

C

Q

See zero complaining anymore, so not so much time of this one I.

C

Can move on, but what we need to be able to shape is that we happy with that champion otherwise tech there. That's what.

Q

Lies dormant names.

C

Would start me fine with it it's just. Basically, we don't use try unless it's a performance issue, we don't use. Try for like oh well, yawn doesn't like exceptions, so we don't like using Charlotte, try it's more more like a performance of.

R

The production I think that, in this case, is a lot of the you know like.

Z

R

Failure is sort of the expected case on most movies, like most of the time of people.

A

Are going to call them they're not going to fail, but like of all of the inputs, you could pass the try open. Nine-Nine's of them are going to fail, like you need a valid input into this in order for it to work once it's a valid input, it's probably not going to throw them. Almost everything on almost every system is an adult. Okay, a library can but I mean.

F

Api seems to be designed for, like.

E

Light up before.

A

This is a feature so.

F

Like in that sense, like failure, is it yeah just otherwise you just.

A

Want to kind of do a little important it's you would do what we can do today to to do. Party invokes and.

H

All right and I have two other questions for this. One I think I might have missed that earlier question for the search searching. What are people going to do with those when they do all.

V

Right for some reason, I originally thought they were going to pass it to try open but not David, I plan to add a name to it. Then you know what.

I

Is their planning.

V

Listen up and you know, yeah, that's not a mutated blue strip. No! It's.

E

D

V

But you can create wrapper around that right. You know, but.

E

The question of what you pass it try open it. Will you pass in a fully qualified path.

A

E

A

Open doesn't take any pass, it could take us out. He's a purse parameter. It's examine this extraneous, not an ienumerable or list.

H

Though so you're gonna go, try call try multiple times with different pass yourself position. Okay, I see I, so their.

M

Name is a patent that they're uh there's a deal search. It.

K

M

K

It spot and it might be none likewise, they see if the path is fully qualified. The ignore the search path, right, iOS.

C

AA

C

AA

C

First, not call open just pass, not fully qualified. The still name are.

B

C

Searches the defaults and if it fails, then you try whatever your fully qualified directories. What yeah.

AA

C

Don't need to append, it is only like you don't either did ever have to read this search directories because yeah, it's open.

P

What everything I understand you just.

C

P

Just call you know: yeah open with the footpath all your reason.

Q

H

Would do a full passes if you wanted a specific one from certain objections? Oh so.

K

You're saying that Sanjay agrees perfectly doesn't make sense. We should get rid of it.

X

That's what I'm wondering trying to understand the scenario where you actually use it? Maybe sister for fish buses can be different.

C

J

C

Oversteer, this is for just also there's.

J

C

I see for search directories which would be like maybe using remove. It potentially is basically diagnostic. So imagine that I call open and it fails and I'm like so.

K

Today for the Diagnostics AI, it's like when, if you add up the net car by the size directories, this is the implementation for that good. Just return, the up context get data. You know some property name because of this bigger the site directories are in the up context. Oh.

A

No I mean no matter what that would only need the search directories for one of the possible search have sex, so it will be wrong for the other end of them. Last.

R

One so I think dead is also factoring again like okay, then the columns data later the other question I was there moving search directories.

I

H

H

Whole nest enter fashion or one time only I'm, only a pencil.

V

H

A sense it is a portable 4 OS, but it's not portable in a sense, it's library code using it right because it's going to be neck for Apple, eventually, all right. That's what I want and what is this going to go into system running around services contractors I'll.

K

Let you know: ok,.

C

And what is the reason we don't make it closer Anton well,.

K

Because of the you know, it's you don't know what the look like that I get broke. A dress is called on random OS. It's out there and stay out by known cases very busy like you eat until you could make a portable proper like that, but it would have really ugly decision matrix based on the OS. You know to decide the wrong times. Gonna have to do that right, yeah, but the wrong time. Does it already right and we build around I'm paralyzed.

C

Ok, I see what you're saying the implementation has to be rented in Toronto, so it cannot be like an oopsie, sharp I know my evil deed yeah.

A

Something personal enough.

C

A

The implementation, that's the same, which we know askance. It sounds like it's so radically different between us.

A

That was limp or CLR.

A

Unfortunately, we need to get that back into MS Corgi.

A

Decided this is not going to sub class a panel.

H

All right, it is we're not going to dispose this unload.

G

To the V remove the default search, dll search path until we want to remove the arguments to try open yeah, we.

I

Thought I believe that our search path.

G

Just don't need that direction. What so, just we don't need to default? This outcome because drinking ah you.

A

H

You're going to pass you're going to get one of those values is going to be used to default list.

A

Essentially, the property that was the default list was not some new control. It was just something we could read to find out what the default or else, and it's only the default for one of the it's.

AA

Not all of the options, so we cut it all, so you renamed it to unmanaged library. Yes, today.

K

In the third bullet point, there's the type of death season full.

I

K

I

C

Also, are the parameter names results correct? Should they be called address and.

Q

House aides for the more without the parent.

C

A result is such a good about what reply he he was killing their.

A

N

A

I

Honestly, I don't know anymore and there's another season.

AB

Who saw the type of acceptance.

B

Or should be like Kreiger, similar to the resort, beep symbol address this jet available here. So what you want to call them symbol address.

L

Delegate a simple name signal.

A

Address it's kind of redundant I mean the result of column, gets similar analysis for the user.

C

Or it does have.

A

This I mean it could be just add this I, don't care about the simple pickets, but well, if you call that electricity just have LT at telling good like yeah this is you can't call it LT Delhi again.

AB

K

The bell: are they try yeah barson I think that I I.

AA

Don't think we ever see result I, think I, don't know. You say that.

I

E

Them all result, actually, my father's always resolved.

P

Really the two ones that I just tried.

C

Yet well, maybe because we've had the same problem, I mean them. It.

Q

C

Q

Get a ticket: what do you sing the Opera organize a.

AB

Potato yeah I'm well.

C

Wait till you have, we had another loans that returns to things and then the first one will be called result and the other one would be called. These are two yeah.

A

No II thought like honestly, the only L tonight.

A

Rim, because every time I.

U

Have to go back to figure out house.

A

With is it outing the remainder or is it outing? The quotient.

P

But it turns out it called out B, that's what I saying it's only an ambiguous. If you retain one thing.

D

The big question is that guy, so, if I want to first, I probe something some mine own path and they able to you, know, handle and we'll move it to the default. Do I pass now to destroy the dialogue? Yeah Selena Selena? Yes,.

A

Yes, yeah: it's do you want system passes? Do you want application relative? Do you want.

C

Anything else, I am not sure. If I, like the change from native to unmanage, we.

Y

Talked about this earlier, but when you had a perfect young me before I, don't care I can drink free people online. The.

K

Other day, like I'm gonna, just.

Y

There in the stem and I'm eclipse, Tanner.

D

Had some actually arguments for why to code, my unmanaged.

M

Are you happy now, okay,.

P

Thank you and I had.

AB

To come back to NATO because it Christoph's the only one is something I'm omega-3 people asking for a managed, really yeah. If.

C

People really think that an Manish is better and the.

D

Argument from tenor actually.

D

Because there is no automatic management of further types native implies native, but doesn't in buy or deny safety.

U

I'm just doing people, children then write your own. The sorry.

E

Alright I think we should go back to this of the Epistle shouldn't the team a lot of time in it. We have more time. Otto was sorry. Where are we so I spent the meeting into two to being on the second hour, and so this was the thing that person wanted to reveal pretty sure with this or thought half-hour and I'm, not convinced I,.

C

Said if it takes longer than half an hour, we are at Hawley, but we just spent half an hour on the nail exactly so on or more so. Basically, this is an abstraction and a default implementation. It's just the implementation is internal and it's returned from the default property. The abstraction is for a pool that returns owned memory of T instances.

C

The abstraction is used by pipelines.

C

They have an implementation that has a slab based slab allocated based implementation. This default one would basically just return, don't memory and return their own memory. The nice thing and the interesting thing about this pool the difference between it and array pool is that you just rent the buffer and then, if you dispose on memory, it will just return the underlying buffer into array and that's pretty much it overview of the type and the.

K

Implementation pulls the old memory objects to r8 8/8 right.

C

No, we don't support ruling on memory because we removed a cookie. Does you remember? Okay I had and you guys all wanted to remove I.

Z

Would say one of the most interesting thing or one of the more interesting things about the site is the right semantics like what do you do if you're, not basically, array pool and returning the exact size, that's passed into read every time, also any size? That's like assign a value right so.

C

The parameter to rent is called minimum buffer size, so it cannot return less, but it can you return more, it's out of memory if I catch, um so we should talk about this. I mean it's a bit of an implementation, but so there are some implementations that cannot return the size. It's either, because the system really is out of memory and then, of course, would throw out of memory, but sometimes it's a limitation of the pool so, for example, slab allocating boom.

C

It has fixed size buffers for K and it cannot do larger. So that's where the property maximum buffer size comes. If you pass something more than the max buffer size, it will throw an exception. I would not want to use out of memory because I think it's it's a different error condition. So I would just use you know, argument out out of range exception. Okay,.

A

But branch is guaranteed never to return, though right.

B

What's the point of having any size, infimum value, a certain Holly.

C

So any size means I, don't care just give me about it? Why choose in.

B

Z

Should it be oh, it could be, but I mean mean.

A

Value is negative, 1 rightly, why what's the scenario in which you want any size proper in.

C

A lot of scenarios in pipelining, you literally don't care, you just say, give me the most convenience size of the batter.

R

So we can return a 0.

C

By popper, or one by one by is typically I mean it's. You know it would be very strange pulling permutation, but the point is that there are scenarios where you don't care. You basically want to leave it up to the pool, so it can return the most efficient.

C

You know size for it for its implementation. If.

B

The minimum is one that should settle value, V, 0 I, just.

E

Say one yeah I mean I mean 0 would be in one particular an agent with egg. So.

L

C

Reason for this, is they like the idea, because, logically, it is one is logically after I. Don't care what size. This is well, of course, zero zero size buffer doesn't make any sense, but what.

Z

Because there are two real okay there's one real implementation: there's another fake invitation, one space on slaps and what's pipeline uses, and that has like a maximum four K size that you ran, in fact, if basically turns returned to either a fork a bucket for the other implementations based on a ray pool, uh and in that case it is correct me. If this has been changed, it returns exactly the size you asked for it.

C

Z

Anything also his.

C

Pockets: okay, it tends.

Z

To closest to okay so, but the risk is that if you say that one for any size, you're going to end up getting the smallest bucket and a rape will nonetheless now using one for the pipelines, version of the pool would be just fine for the way we typically use it, but for a pool it might be less efficient to do one bite for every call to Rhett. Just because maybe you want a bigger slab, um it's one of those things where it's like.

Z

Okay, I can split up the data that I'm writing into these buffers, but I'd, rather not so like. What's the best way to represent that, so any size says to the pool choose what you think is optimal hurt. The pool I would think so that the a size should be.

K

As unique all right, it should be minus one. It's used.

W

M

In a legate's indication, not bullying correctly.

C

There's not much you can wear sophist for even a trifle I, don't think it returns ever arrays of size, one yeah so, but granted it probably returns arrays of size 16. If you ask for one.

K

C

K

Know you can diffuse the pool venue, you commute kind of some size of buffer that you want that you can.

K

You know if you can disallow buffer sizes of size, one or makers.

K

Completing size of the buffer that they might need need to handle like, oh you know, and if it's too small.

B

K

It up to do right, or you know something yeah.

C

I, don't think this problem will go away, though, but.

K

Nobody's with the booze do that for that today,.

Z

K

Z

If you like, having a any size, set, no value or you say I, think any size and value is good. So.

C

So now, why do people care whether it's intamin value or minus one minus.

K

Ones like your small, natural and bite, you know if.

W

You have bought.

K

The 80s and 90s tiny bit smaller card I just wanted to strong, okay.

J

If it is minus one, so if I quadrant 2 is minus 1, you will accept this. Yes, now it's that see any size, it's gonna be any size. So.

Z

Romantical takes any size 2.

J

Right so the parameter for rent it can take minus 1, yeah I mean it's an integer. You can send at night as.

B

To its own word, when.

J

I guess minus 1 for rent doesn't make sense to it. So why was changing.

C

Because otherwise,.

S

The sentinel value will do work this we have to accept, you can pass in a tuple or something, but it's not worth it right. We look at 0 as a sentinel party because it I mean zero, so some nonsensical for.

E

Every oh solid.

S

E

Actually did, but to me, like one turns out that you never return. My and.

T

You return some other buffer size. That's.

E

Really, zero on one you.

T

Can actually return? That's.

E

T

K

It's like oh, it's like, but with like in C++. You can do mal zero and it works just fine yeah and you actually do take advantage of it. Sometime. Okay, fine, get.

C

Rid of it so minus one is fine. Another argument for minus one, it looks very nice on the printout from emos API review. 2 versus int min value, like you staring at some large number, is that she don't.

E

Fear my reread pics is that, because there was annoyed with what's the rendering context.

C

Well, because I found the issue- and it was pointed me to a repo and said change this- the.

A

Next raid is not your problem, it's eadamson really, haven't you. Never ever ever have a structural nap time ever. I'm gonna. Stop you right where you stand, but.

Z

The reason it might not be a good one is we have an implementation that pins arrays yeah like that instrumentation as a constructor you never put on the F chart yeah. It makes.

H

Sense can somebody educate me why whatever pass any size to it, I know you guys are talking about I'm still not following.

C

This you know, process. Let's say you process like data. That comes your way and you need just buffers. You kind of don't care what the size of the buffers is, because it never ends on the second.

H

Asset, you want to write it. What so, they pick a number and pass it to the polls and why do I need to this episode? What.

S

H

Better than you feel exactly because if you pass a specific number, two.

C

It's more efficient for the pool to return u4k the night cream, for example, array pool, maybe is it ran out of buckets? It ran out of the you know for case chance, but it has still 8k charged. So it could give you eight K without allocating, but not forget stuff feels very odd I mean. Would you add this to repose.

H

Well, any size.

C

I

Is it gonna get rid.

F

Of pleasantries, but so we still have the any size, even if it was negative, one that seems sort of an aside one in my life, I, basically stripped the any size field and I just added minus one directly to the decoder. Fine.

C

You know what it ought to have that yeah.

E

C

Good action change because it's annoying to have this any size, yeah roughly constant, but you can't past.

H

In went down to like a red pool cause, it's not gonna handle it right. No, you.

C

Can have, is this so you're gonna handle.

H

It explicitly and only persisted.

C

Yes, yeah, because this is an abstraction at a pool- is not really an access. What.

H

Is an abstraction same way. This is an abstraction. No, this one is chose a repo ready. Yes, oh yeah.

V

H

This questions going to be what, if we didn't, have the own memory being in system memory. Would we also just put these this rent directly on a report instead of having a separate Ike.

C

No because then you would have to implement an abstraction that gives you either.

C

Cannot do it, for example, and their memory pulled. The tree turns that is based on native memory, cannot reach her in the race? Okay, so that there are multiple plantations of this kind. Just not a.

H

C

Are actually two implementations that are shipping and there's an implementation based on native memory, which Steve dupe asked me to warn you guys? How do you get accessed on a public API, so I assumed default is always going to be the rapist, so this one is going to be they're able in pipelines that is going to be another one which is the slab allocated, and you call it slab. Yes, that's what they called it. Yes, I, don't know if it's a name that is a standard name, just means lighting of larger racing.

C

Yeah allocate one massive array and then pin it and then just give you slices so.

Z

Big enough for ADA end up in the large object you potentially and then slice it up. There.

H

Any reason why we wouldn't have the same structure as we do on a repo and I have the four piece called shared and have great methods to have multiple memory pools, so there's no way to create I. Think.

C

Why wouldn't it be it's a multiple of what may open variables? Why should one native and one mention where are you I, don't to ship native yet, but I think what we're saying is basically the create method on this. One could basically just call underlying irate that create yeah I'm trying to fish again like lose ApS or the rape of.

H

It because it's bit cool article II a lot of the same thing. It should so a good witnesses of what detect a default. One I mean.

M

You clearly have multiple: they.

H

Gets a default like that.

M

The father's basically.

H

The same way as a reports, the shared yeah.

E

And then there you have, you can create multiple choice. You are saying so. Instead of having a default one, you actually expose the derived type and like make that just Newell know, you have your default. How you get rate.

K

One we have create metal, have written.

E

K

That is like the problem with a typo. Is that the way it's designed today, I.

K

You actually come, you know, like Ben Adams was like looking at that and the abstraction curve. It's like significant chunk of the overhead to come from the memory that you have to go to buy property, go to virtual method right. So it's like we are in flight that you know tries to creatively avoid this abstraction to some degree, but it's like for any I think it was kind of a mistake to make it customizable helping just one right for this. One I think it makes more sense, but.

C

So I definitely like wisest suggestion to rename the default property to share it, because people moving between those two different poles. They don't want to.

H

C

Changing thing, whether we add the create method I could that I could I don't like it's not it's not a scenario.

K

That people asked for it to be good, I, don't know, I I think it's like that. It's a mistake that escape method I'll be able just keep.

E

In mind that those guys show up in the providers, you may not want with static share like if you derive like, if you have a native memory pool that you have, and you want to share native memory, for you basically have to hide it like if they call it something else and they make it stick, it could just get when you're worried about the static API should I have a drive types. Yes well,.

H

E

Should work I I, understand that, but I mean I'm, not sure why I wouldn't matter, because these are like I mean like if you, if you're on, let's say your native memory pool and your today, the memory pool of TDOT shared code looks fine, it's just you don't get a native memory, pull back, you get you get whatever this deal. Implementation does right. I go tentatively to that design you, but you would have an abstraction that is pure.

E

Then it would have like I, don't know default memory, pool of T as a public type and that would have like it dot shared on it, but people they want to model that differently. Otherwise,.

F

E

F

H

A my asked question for apparently with it rapport so assume return is just encapsulated in memory. You just dispose it to return it for it. Okay,.

A

And this other question: what happens if you have a native memory pool and T is a managed class like person.

Z

W

C

The same thing happens: if you just put an e-wrap native memory in this pan and you can assign it. You know one of the values to it as an 8 by as a managed object.

A

So we're because their references, rather than the actual object itself I guess now. It's it.

K

The if you in most places VF roadblocks that VSS now don't do this like throw exception. We don't have it on spam. We do have a constant like menu. Then you have like you know, struct with reference types or reference type and page span of reference type, and you call the constructor that takes void star and in that context. But if you just create the span of object and I start sticking objects inside this panel, it works, but you pay the span out of one over pointer.

K

Now we did the constructor that takes the pointer, repre, really.

C

Yes, what if what, if I allocate and.

K

Same for stock I, look at its fun, that's the stack, elevates pains looking for them. Similar reasons work only for like the raw data not up to the pants and.

C

So I assume that we want exactly simply here to yeah.

K

And I would think that.

C

I had negative L or.

K

C

Then we thought various plated. It would throw. Basically whenever we.

A

Try to create a span, so it also sounds like owned memories of disposed routine knows what bullet came from and get reduces all that the correct cool, yes, and if and because on memory has its own finalized or safe, handle or whatever, if I forget to dispose, it will just clean yourself up great all.

A

Can we get rid of the destructor I mentioned else.

S

I always don't know what their goals are, so the distracted aims like we should get rid of it. Yeah.

A

No, no, why the de chine you can put it on the drive type yeah, but their structure should only ever go on the drive type. It should never go on a next limitation that has no inter or void story, reels, the reason being that now, every single subclass of this type, including the fully safe, fully managed to rape type or a rape hole. Okay now goes in the permutation okay about it.

A

Right also, look at like system Windows component or whatever, which has a destructor and now all of.

J

We have another issue of on memory that can change it to some interface. Like so should we use the interface instead of their own memory.

H

Dear ones, that happens yes, it's.

K

W

K

H

Logical pockets only can be changed at the same time if it happens to change.

A

What happens you just dispose the default Network for know what.

W

S

What do we want it to do? Probably not let's grab the system is one.

W

K

S

K

Might define or just dunno up depends on say what's on accept it.

F

Y

K

Know like it's like it might be better.

E

Because it definitely like, if you start disposing random people's memory pools like you, have a bucket your problem, this just waiting, no.

K

You know like a valid, but that invite to know of implementation would be helpful is if you have API that you know or something that takes memory pool to allocate from and finds that things go away kind of wants to dispose. It dispose the memory who you get it from right, and so, if you know get it on the default memory pool, that part has a special check. That says out. We finally great if I'm, not gated, on default memory, food and dispose me or device do not think it.

A

Also trigger an MVA watcher if you want to be in on attend behest, and you can't.

W

K

W

The similar thing is, if.

K

You dispose like the converse things, I'm, not sure what what is a grateful. There does have two sports balls.

W

C

I am Not sure it make up this bowl.

K

Otherwise, they stayed standing matter now.

S

K

Is like DGC thanks, Carol I taste like nothing police box. You.

S

Know I'm saying like.

K

If you want to have eagerly debt-ridden pockets, but I'll do it have you can get eagerly container, but you just like stop referencing this stuff and no then we'll still close to the energies the bucket. Well, let okay I see it's kind of a different program today who is leaking today, but maple.

E

Does have to suppose today it doesn't.

C

Know but IIIi think I saw some issues. People were basically saying, like I use the right pool now. I'm not gonna, be using it for two days, but it holds to all the race side and I like say for now: I don't need them reallocate when I call you in two days well,.

K

It's more take units so.

T

Are you saying the noir thing.

E

For the sort of share this better scenario, like better semantics, no, but everybody has some special case.

C

Yeah I think so I mean the problem. Is it just general? It's not only about the shirt, so imagine that somebody implements I mean.

B

C

Their custom pool like in pipelines and the pool is being passed to Allah. You know to use your code, you kind of only want the owner of the pool who created the instance to be able to dispose, not everybody who wants to rent the buffer, but we kind of you know we could implement it by complicating the IP is a lot by having, like you know, the owner view of them all and the user view of the goal, but it just it would be over engineered and.

E

Like my general thinking is people like the people that ran should never call this boat right, it's basically, whoever like selects the which pool two units. There should be a higher exactly so that guy should know where they came from.

K

Share create right, I mean it happens is like if you just allocating some component, that needs a pool glaze and you know, and you kind of created with some pool and then you just say: I'll go like I. Don't care about you anymore. You know it's like. If y'all had a lotta.

C

Friend well, I say this is a simple email saying: yes, okay, the code that actually calls new or whatever some static method to get. You know a new instance of a pool. They should be the only code that can call this post.

C

If you create a ball, you get rid of the pool. Well, if you just use.

K

The pool you just use the rent method, you shouldn't be a Valerie itself, cementing it fast, you might get fasting account create a fasting. Then you pass it to somebody, and you know they oftentimes they're fishing boat disposal, but sounds because yeah, but it depends like what button you site so.

T

You the wrapping pattern that that that is true, like I, mean.

K

E

We say that our writers, actually throw like is sorry actually disposes. Also I, don't know whether I would redesign the api's like this today has other boats, yeah I I can wearing like no obscene to firmly the most conservative choice. I'm. Definitely.

Q

For the day for the shared.

H

One for the default one: we just have to do it yeah if there's nothing, to dispose anyways just make it a no op. How.

E

Do you mean my share versus there's only one right, we just me name the only.

AA

C

On this one, if you call these poles, it doesn't do it it's a shear in. If what, if you implement your own abstraction, you incur it from this one. Of course, this ball would do whatever you want supposed to do.

H

We finally exposing publicly the other ones. The array, poor memory pool and the ratable is already exposed.

C

But an instances are shouldn't, be public. Oh the implementation of this one. Yes, I, don't know that I again, we can expose it in the future, nobody's asking for it. So I. That's what.

B

C

Think that's good showing for an additional fun.

H

A

H

I was asking whether or not we're going to implement, expose the concrete implementation memory pool. That's based on a repo, probably oh, I, see as its own.

A

Concrete type, rather than through dotty.

H

Old, well still haven't thought default or shared their, but I was just wondering whether that for people who want drive from the repo version so did default is guaranteed to point to a managed.

A

Array is that a code agreed upon her well, I, don't know we want to so you know the documentation say this is a contract. So the reason for this is there is potentially a race condition at potential, a B with this. If it's not implemented, if it's not backed by managed by a manager right, imagine a method that has three lines. First, one our pool equals new native memory pool second line. We don't allow you to say mmmm, you know it's an abstract class.

A

Do you need a miracle second line, VAR n equals pool dot, rent whatever dot memory? Third line bar stan equals mem dot Sam? What are the lifetime guarantees of span.

C

Well, you're saying at some point somebody disposes this native moment.

A

And I'm saying it's because because neither the pond or map is referenced at any point for the remainder of another, then she's free to reclaim it and now span points to.

R

Now this, if you and creates referencing those if.

K

It's now, if it's managed, if it's if it's doing La poule. Yes, yes, the.

U

Info for a pool is.

K

Good, if you are using native memory, yes, you are right that you have to be careful about taking the life times yourself. There's no safety in words. So.

A

This makes me think that if we do explode.

A

Which is default memory or something like that? It would have to be managed in order about the situation I just mentioned, but it's just the only thing else.

C

I asked because the pool can go away yeah the spawns memory will not go away necessarily if it's a marriage.

A

Pool that's correct, but if it's in a table out.

K

Its name if it can go away well, like none of my money, but.

A

The thing is I've.

E

Now written fully safe code, which code.

W

E

Get this point here like let's say the method ends here: I don't know, did you don't use either pool no memory at all well, buzzies plan.

C

No, no, you need to remember how how owned memory works. So this meant memories and spawns owned memory. Write this owned memory controls the lifetime of the native memory. You.

A

Can also disappear.

C

A

This isn't here right here, but it doesn't disappear. Nothing happens so right right here at this exact point of memory and pool are available, producing because no one representing more.

C

Well also so right at this point, you know, but it has access to spam. Also well, I mean I I use.

K

Them especially, and that this method very distinct in a method and.

R

Can you return it yeah, you can't so there's nothing, nothing in the kind of the.

K

R

Doesn't doesn't get into a you know the rooms I can't lean on it anyway, so here here's something where we don't don't return. The spam, like.

A

And then maybe maybe here you do likes like buffer or binary primitive, stop right into spam. The number 42 right, the api's and we're introducing, but the thing is like immediately after line sex memory and pool can be juicy which means that this code, which is all ostensibly type saying theoretically Canadian yes,.

E

I, don't know who you're thinking would prevent it where.

C

E

Do is examine when time, when this object, which is fine.

C

So the only know what I'm so okay, there is a problem here, but I want to make it clear where the problem is native memory pool can go away, it doesn't affect the actual native memory. Is this object called on memory rights insurance, the lifetime, whether they also go away absurd? Aligned of you know when, when basically memory so just wanted to make sure it doesn't spend on the native memory pool lifetime?

C

Correct depends on the memory right, so you're saying if I basically disposed, the pool I will not destroy all the instances that did it that this pool giving away it depends on the implementation of the data, because.

E

I would like, hopefully, the Canadian. We pull the finest that you just did to defeat a memory like the native memory, in which case what the objects do is relevant. It just no point you're, basically return memory, I'm, not sure.

K

But you know, even worse case is like you can make the do stuff presence panel by and it also compiled fine. Now.

C

So but email for your comment, it depends on the implementation. I would actually prefer an implementation where owned memories.

S

Completely resolve the lifetime, I would say this is more an issue of own memory.

A

Then very good, maybe all I'm saying, is that this code works type site. Would absolutely house review and maybe yeah.

S

And I would say just remove the pool and use our memory. He says: well, so the code can be written to be more correct and not ad.

C

If you call after after you get memory out of the pool you you can retain it just and then it.

L

Will not eat me right.

A

But not get rid of them. That's that's! Assuming the developer knows to do all right like do. Would we have tools, it would catch this.

L

C

You don't have to do this. What you basically just have to go after.

S

Z

To call memory dots so in the memory pool, use or pipelines, we currently have some compiled of time flies, which we do have our own to bugging, which will show if you are disposing, pool without everything being returned does retain due.

A

To the idea that comes I mean I know, there are obviously ways to address us, like you put a using statement around our memory wall Bob but, like my quite central point, remains like the developer, wrote code, which was ostensibly types, a personal ad and.

K

And that's like fundamental problem with the would be the memory and pooling and native all rights like did he had this program even even before by the this.

Z

Memorable API and finalizer makes it a little more implicit than it would be if you just used on memory directly, because the finalising just run so it kind of both. What I was saying. I was Stefan said.

C

S

B

C

Because it gives you those own memories, it and it's.

S

M

Old memory factory you I.

S

Dated Lee, oh.

Q

Let me just again paste in what I have written up based on our discussion and type checked. It again.

C

Sure so we just I thought we decided not to expose, create we're gonna wait till people want it, but that was a decision on the concrete instance but okay and we decided to remove any size which is removed. One yeah going to change your keyboard, I think.

B

So because it's called shared on Eric, but what about the I think you meant to cover about native memory. God be God, has a shame from one or a pool. It's.

E

Not it's not ready to do name, it's just the fact that you have basically a member on it step, but type that is extensive, alright, because this guy shows.

Q

It's an interest, everybody calls it shared all.

Y

Q

B

We usually use mats and shelf maximum that we don't police a Sputnik. We.

E

Have used mix before they usually the problem of Mexicans police, like this three other words, usually like minimum buffer size, for example, it is not on abusing the time it gets. Ridiculous also, naturally have Max and mins. It.

C

Will find I actually think that we had this discussion at some point a year ago and we decided, let's just like make it official. We use mix in mice and men, half.

A

An or just like you wanted 38 minutes.

Q

All right means if a few more minutes actually use and.

B

If you're doing, based on some ID, the string like API is I updated at the very bottom, unless somebody.

Q

Has a size where it says epic: they will take forever. Oh, yes,.

A

It is actually going to read to us from the earlier piace exactly, which is that link update ApS.

B

Here, look below it says.

F

B

B

The key questions here are: should easy methods be generic.

B

Is the remove, replace and all the other ones that solve them, return an out parameter by straighten and solve them? Don't because the user can know ahead of time already as a constant? What device return should be? My students should be so they don't have those. Those are two main issues and sample causes below.

C

So, which could be genetic which all of these ApS could be genetic or or.

Y

AC

C

Lower just a bottom half back here, all the king came api's. I hope trim could be genetic, that's actually what asp.net team asked for right. It basically said: I want I, have a battery of lights, I want to just trim. You know the byte of value. Five and eight do.

B

We either have byte or specific overloads for some of these, or do we just have two so before we get to this question.

C

So? Which half of it could be made? Genetic.

B

C

No, it's not I started.

B

In half, but like most of the next had left could be genetic as well, because just adding elements.

A

The thing is, we would, if we made these generic, we would want to special case certain types like charm right, because string, dot, char, doesn't just I'm, sorry string, dot trim, doesn't just trim space I, believe it trims. Everything that qualifies as whitespace do.

Z

We want to match strings behavior for trim.

Z

Is that what's happening with the default overload or chiness.

Z

I hope that I would personally like to have all of these for bite, like all of these extension methods, to read only span up by it, with the exception, of course, two upper and two lower. Oh yeah,.

C

Well, so I think we eat. Last time we talked about this. The trim that doesn't take any parameters, but this one doesn't make sense to be on bites. All the other ones do head.

S

Trim doesn't make sense on bites yeah because of.

Z

S

Z

Was saying like I mean it's fine, if you spun of bytes, we don't need the first overload. The other overloads that right. Okay, the.

A

More station, can you beat it so the issue is string, taut trim is not trained, will trim white space from both the front and the end of a string, but white space isn't just a like 2o character like your like 6 or 7, maybe even more characters in Unicode. They are considered quite special. Would this have the same behavior as trim trim yeah when it will now tell were special casing chars as a team inside the save it.

C

You guys that it's so basically what he's saying is white pipe white.

C

So it kind of just takes spider bytez, because then you would have to say in which encoding divides our advance. The moment you pass the parameter shrimp char, you don't care about it voting because you explicitly pass. You just want this number to be removed. So all the three methods, except for the one that doesn't take any additional parameters, they could be Oh bite yeah, it's very explicit what they do.

C

Yeah, there's no ambiguity and same reply: click trim, start trimming and other than that, the default one will just be span of char, which makes it a bit weird, but and at.

Z

The point where we're we want the overload for read-only span a byte for everything that is an encoding specific. You could just make it tea right, because anything that we're son by it would work on to you right. So.

F

What's like what zeros or like basically ASCII space.

Z

um It depends the only thing that I think we tried calling the trim method on once and I think we even might have just spent okay stood like to have our own strip method is for, like headers, so various whitespace characters on either at but its ASCII. So it would be nice to like do that prior to creating the string or getting actual characters.

Z

B

That is similar question about Pat left, padding the bytes with zeros or is its best characters in this case again, you would need encoding. You.

Z

Pet, it all I, don't think you doing today, Oh is there a default pad one that doesn't take yeah, there's one that doesn't take a padding car, okay, yeah, then I! Guess you want to have that for byte either.

Z

Or 40 or whatever we end up doing.

C

Interesting, so what are the parameters in odd, like the last two parameters? Reverse.

C

Before before the car.

AC

C

Try to be consistent with existing API, so it's just yeah.

B

Because it's just ApS, the only difference here is that we have to have a destination Indian a destination object, so usually string. Aps has totally the heading chart, so I ended in education instead of talking or you know, traditionally, outcomes of your an accelerate yeah.

C

I'm not through with this there are. There is no alt parameters here. Right well, I mean the destination.

A

Destination is now primary. It met its route to.

R

But how it doesn't it it's a tonic.

E

I thought, logically, you must expect destination to.

Z

Be always a lesson, try to acquire argument that.

E

In charge of them switch whether it I stick.

S

Well, that's the.

Z

Thing is they do not required argument right. You forcing the.

S

Tradition for luggage, oh.

Z

I guess for some of these api's or all these API is required. Okay, I see, okay, now right all right. So what's a pallet with.

A

But the top one will probably be spaceless figure. That's what screamed out as well. So no we're special.

E

Case in charge, oh well, I mean that Vinton what what? What? What what shave beard me I mean I'll, be basis. Amy, I still don't know how these specially castings right, I mean like I, would I would expect. You would do this one here, as as we only spend a bite and then this one only is we'd only spend of char, but if you are invoking it on char, both Oberlin supplies, logically, we'll still want to have heading.

A

To be the last one, because it just makes it clear: it's not one, you would, what would the default value be for we don't for of have attention, no I'm saying it's, there wouldn't be one there wouldn't be one. It's.

M

Just in both overlooked supply, if you invoke it honest on ahead.

A

M

See so that's what you're saying the orders, your position? Yes, because otherwise say they show up in the roarin. Sorry.

E

K

Do we believe that you know this dislike safe bed right that they, you know, operates on Spence.

K

Kind of you know the opposite: editing the string, I kind of want to pet it and remove this thing, and with that thing, and if I look at how I would write code with this, like I need to do crazy amount of buffer management myself right like to grant you know ten different things from a rainbow land and also I think so. This is one second.

C

One is with strings. Padding is kind of tricky because you have the original string. You need to somehow create a copy and have like you know on both sides. You have to have room I, it's tricky. This one is, you can expand, apparently it's larger than the data slicer. You don't have to slice you just index to the last location, and you put the thing that you wanted and you index to the -1 location and you just add the character to Pat, laughs and you're done. I mean it's just necessarily.

Z

More complicated than just calling add, left or Pat right and you should have to zero out like the initial buffer for the things that you're not writing in or whatever like I, don't know like it's a few lines of code. All right, then you are using this API, so you are personally doing it.

K

Because if you kind of are sending it somewhere right and at that point you are most likely using this, like other spanning both writer side. That kind of.

Z

Yeah I mean in casually when it uses as a day. Trip is the only thing that was the absolute. If I myself in the.

T

Same bonus as grants and.

E

I mean like all this API, it's trim pad even remove and replace I used them on strings when I want to hack up something fast. You'll want to do something pop I, don't you can call them on strings I call the music on spring builder.

J

Or some other API, even if you want to use it fast, I mean how we are going to bring messages. This is not as.

C

Bad as you pay only of.

J

Which one the trimming and the party to a Baltimore.

C

Well, training the implementation is, is not that hard? No, it's hard. What you do it linguistically or organ.

P

N

Did you consider sorry two best characters, you smell something I have more diverse.

J

During has options the best like culture, caricature or ordinal, or in other projects for trip the dissolution. We have a proposal which is approves a support to other options. Yes, but it's not implemented. Oh.

E

I was under the impression that shrimp only handles like you know, basically, whatever.

T

J

About you in a second, what you choose tomorrow,.

Q

I think that that limitations, lots of us go straight forward, but.

B

We could just, for example, for char or source like Cooper just pass in.

B

Yes, do all the news for some reason over, but whatever put up. If we tried to add new api's, we could just pass in the same order to the online chat idea. The same way they to a variant. You can just use tar to operate it for each character. Now.

K

If you cannot actually I like soda linguistic things, I like feeling kind of like new 2d characters like the excel in Unicode right, one kind of you know letter can be multiple. Car tights, like German, has.

Z

A set it's like one of those examples of these which grows.

B

Or shrinks yep.

J

My point is like: if we need to support this, it will be more complicated, not just an implementation, but we will have to support some other options to pursue and.

K

And it will be super difficult to implement it in the portable version of this panel.

C

So I I think we yes, it would be good to have these other options. We don't have them on string either. We.

J

Have it is not.

C

J

What was that I think? It's really approved that supported alone I.

P

Z

But this was luck, moves on one year so to the point about two upper and two lower, potentially changing the size of the string. If you will I replace, has you can bring work? We don't choose size, oh we don't, but I thought you said you got something approved to do that or is that something else? No.

C

This is something like that. Well also I mean this is a separate issue about to upper invariant and to up.

C

The to Apple was meant to be do exactly the same thing that the string method us, which is culture sensitive, but maybe it's a bit more difficult to implement than just calling the underlying API. But we call dependencies yeah.

J

We can it's not stressful, so.

Z

I mean talking about the value of this API I think this came up the last meeting. We reviewed this and like teams, Tim seaward, said that the finance world runs on trim and I feel like if you're like consuming any api's. uh You know maybe you're at such a high level that strings and stuff or fine you're, okay, like trimming allocating a new string, but if you're optimizing for finance kind of situations, maybe you know yeah.

C

This one doesn't.

Z

Look good because.

C

Z

Agree: yeah! No! That's so I'm just glad.

C

S

Z

For these kinds of operations and savings allocations for sure.

P

Yeah I think we should add the shrimp operation. The pad left are now convinced we shouldn't.

AC

You can basically just do it yourself like this. You know. Does that not apply to trim too, though it's essentially the same thing just perverse instead of taking away the car patting car you're adding code, but it's tricky to find what you trim off versus.

C

Bad, you basically are saying: I have a buffer area and he did bite at the end and this at the beginning. While it's.

V

You know to find.

C

The locations of these trim is kind of like you, first have to know like how do I find. You know the the thing to trim off so.

AC

Trim start that doesn't look to see if the first character is trim care. It goes until the first instance of trigger. Oh that's,.

Z

Not now you I think you understood, trim correctly the first time if the first character isn't a trim character, you nothing happens. That's a nor the ones. I think they're, both kind of easy but you're.

F

Z

E

Yes, so normally the one that actually has to take it out or like trim and heading and apart, but all the other ones that compare contain, starts with advanced super doodles.

Z

I think those are actually super. Super useful yeah, like I, think the value to this for me is not having to convert these into strings while doing these kinds of transformations. Just to save allegations, I think, remove and replace are very useful.

C

So the first section, the first half I- think the house will. The only issue is: do we want to have the byte overloads and I'm kind of torn, because we cannot make the first one to be by and then the moment we make the second one byte. It's gonna be weird: it's like. Oh now, I need to pass. I want to pass the trim character. I need to cast my span to span of byte, so I can pass it to this method.

C

It's we should just have the ones based on charts and if somebody in the future wants fight ones, we should add explicit ones over either T amigas. So.

Z

The web runs on utf-8, which is oftentimes more than that. It runs on a ski like if you look at a lot of api's you're.

C

Arguing, maybe what I didn't explain supervisor if we want, in addition to the first, have ideas that operate on bytes and not some other things we should have them I'm. Just saying we should get these yeah.

I

Z

The encoding based stuff is a more tricky right and also you're saving yourself. Why.

C

Are not convincing.

E

Before, like to me, like I, mean those ones here to me are no-brainers because they are like trivial um now, this one is well trivial, isn't like they, they don't give up spent, but they just give you back a war right. They are hard, so they're they're, like somewhat of expected, I, think they're like same semantics and they're.

C

Easy to call like, let's talk about first half, first, like the chip, do you have a concern about the tree method? My.

J

Question is how will be lamented four characters? Yes, how are we going to implement it? Is it linguistic or ordinal exactly.

C

Like this string overload, kissing.

J

Good not exactly.

C

How strings work, if you, basically the semantics the tests for this should be the test takes the string called the string method then casts the string to the span of char calls this method and compares the results.

AC

So to be clear, so we work with strings.

J

At some time, where.

AC

J

Are going to other constraints right well for some reason, if you call the string you'll end it so.

AC

We just want us a metric to decide it's for the test that will do the casting Act.

K

I think this in this English invalid, this should be called memory extensions and whether it will be in the portable system that memory surface or whether it be net corrupt specific.

K

So, if it's like all you know like, do you want more extensions to be this dump dumping ground, for, like all sorts of you know like chart which are based globalisation, sensitive kind of API side? Well,.

W

K

Funding and they also be difficult environment as a you know, variation yeah, okay,.

C

That's a good ended, that's a good point. So.

E

That, given that we're running out of time again, I really think we need to spend an hour for this thing to actually segregated out the things that we think are easy foods and then the rest just get more design time on, because we keep doing this half-assed thing I mean even this one. You don't be neatly.

X

As you're comparing.

A

It does take a if the Overland's that exists to take a culture info and a string comparison by default. It doesn't work. The live link right in these casing is you do think you got an, and there is a boolean parameter for case n is 1 yeah, but this one is like that too. It's just.

AA

K

But this the thing is that it's about having this thing.

E

I mean this goes back to what Ben said as well like to me to me honestly like. If we, then she just constrain it down, do the things that make sense every single span now I think it made sense.

K

Okay, what I didn't have the other ones? I, don't.

C

T

So like me, he.

C

Didn't want to make the charm methods be overbite, he said I.

E

Also said, like even those Watson strain sea bass, it just never cause basically, today call that not.

M

Only heard they hosted.

B

M

E

More techy like okay, what what is the? What is the thing we agree on so far so.

C

I well different people agreed on different things. I think he I'm just heard this a good point. In my opinion, many of these first I don't know if people agree but I, like the first half I, think an.

B

Alias already type of api's.

C

And I think IANA the good point. It should go to just caller lip and quorum, because otherwise the implementation will be a misery. So it's not a portable API. It just goes to a different. You know to call it.

C

The second half is a bit more tricky. I, don't know again. If people agree with me that I would just remove part left and pad light, and not do them. I mean.

W

It's try to cross over.

E

We see the first half which just refers to the train was correct. No.

C

Trim equals compared contains starts with ends with white space. Up to the first comment and all.

B

C

All on char, if we want bytes, we will add them in the future and in fact, bytes don't comfortable with the globalization issue. They probably would not go to college, they could be totally portable because they are just you just search for the end. It's it's a helper.

Z

So I'm gonna keep you up until I, so.

C

Now to upper to lower to me this one is not such a clear-cut API.

C

Operation in place, or not so there's maybe a bit more discussion than we should just like. We are running out of time, so I would almost like a little different stuff and then the LA and then remove part left part of pad right and everything else. We reveal next time so.

Z

None of the two upper to lower invariant overloads change, the size of the destination from the certificate yeah.

C

They don't change, but I think the API is now specified. It's not clear whether I can call it on the same buffer, okay, which I don't know if we have a solution for it, but we don't have time to even discuss it now.

B

You got really quite a simple.

B

This the input is really is bad right.

C

Well, I could have a read/write span and pass it to read on this file and.

K

C

Know you can tell the.

K

Destination to be like you know, you can have the destination to be overlapping with the input. Oh yeah, so yeah.

B

D

K

Different types represent yeah, so.

D

You guys mention the first half is going to be. You know specific to the runtime right. Do we have any complications heart to put? Is HD allow or like class and stuff? Do we have any restrictions in there? Well.

C

I think to reuse the integer current implementation. It would need to be in color, correct and.

K

We would read provider here the first half in particular the you know, the start date and end date and it's y space I. They are kind of just another extension of these one ization of the college surfaces. We have done it very, very divided implementation to operate on spans internally and expose data api and just change. The existing API detects thing to just call that Steven.

K

W

K

W

Does it mean which times can they go consume your memory, extensions.

C

So we already have a type inside curly bits called span, and it has that.

K

One is just like internal helper type: that's not the public back. One.

B

And the span cast, which contains sections right.

K

That one isn't in the public reference assemblies, it's just like our plumbing type, to deal with the fact that the thing is played before that's.

M

K

True correlate and the collar facts, and it should go away once you can make the system memory to be in correlate so for, but you know all the different reasons why.

AC

Did he start stuff to be called specific, just it'll be slow, otherwise, no.

C

It's not only slow, it's very tricky to implement because they need to have the global access to the globalization. So.

K

Yeah, this think of Edison pulls in a complex machinery. It is it.

B

Subtree, maybe, as volt requesting compression.

Z

Required comparison.

C

No well, no, no, they do the first one, the first one, the first one does not the other ones, because it needs to know what's the white space. Why.

AC

Spaces are culture, specific I.

N

G

AC

K

Situations were, but they are at least you know, kind of the culture day that specific and you can be. You can oh, what's.

AC

This- and this is just you know- good category, yeah I, don't think we need culture stuff for the first overloads, but stripping.

T

Light space event.

AC

Okay, that doesn't help as much as I. Don't think we'd want them to be in separate places, but, okay.

E

So did cities they can all go memory extensions again, so at La Silla like what we.

I

C

I

C

Every extension.

E

Switch type should they go on yeah.

C

We look, we don't have to. We need to the side so.

K

Maybe it's not as easy as you can close that it needs to be like you know, globalization, extensions or something like that. I don't know.

C

All right next time, but we have money from it. We make progress.

E

You want to go somewhere for food. True, sir. Yes,.

C

W

Earnest in a globalization issue, honestly or.

E

Upper and low because it's the thing I mean the implementation of these types- goes with the collab anyway right well,.

C

As was the decision, it has to be there, otherwise he cannot implement equals all right so like what does it mean? They can't be memory extensions, then, because memory extensions is not inevitable, but why.

E

Don't we put it in the scholar for.

C

Very complicated reasons, but yes, it's not there and cannot be there. So we have decided the pianos talking about scold span right. It is basically that Ms Khalid version of memory, extensions memory, extensions by design, is a type for portable implementations that we didn't want to have.

C

We wanted to share code for memory extensions. If you have something in MS Kolob, you cannot share color code between it and the portable sir.
