having a terrible headache

and i can't stop sweating lmao

01:11

what is happening

gg

TsFreddie

and i can't stop sweating lmao

im not an expert. so i recommend visiting one, be it doctor or ER

01:49

also if U have stuff at home U can check blood pressure etc

no way

most random body problems appear in males 25-35

its prolly just a flu

ibuprofen time

get well soon

oh no

are you dying (edited)

oh no

It's joever, you will become a spider in 24h

cool

If the ibuprofen doesn't help your terrible headache, I'd suggest getting it checked btw

Learath2

you say that like i know how to get checked. going to a hospital stresses me out so much

08:23

TsFreddie

If you get blurry or double vision, or numbness/weakness in arms/legs definitely go to a hospital. Stress/anxiety is temporary

08:26

Other than that headaches are mostly fine to go unchecked as long as they go away with medicine and don't keep coming back

08:26

I'm not a doctor, this is not medical advice. I just have headaches all the time

Learath2

If you get blurry or double vision, or numbness/weakness in arms/legs definitely go to a hospital. Stress/anxiety is temporary

ye, i'll probably know when i have a stroke or diabetes

08:28

TsFreddie

ye, i'll probably know when i have a stroke or diabetes

I know one person who got an extreme headache, decided they could sleep it off, can't use legs anymore

~~that's awesome~~

08:30

i just wish i have more energy for packing and cleaning up.

08:30

my flight home is on the 16th and i still got a lot of stuff to do

TsFreddie

i just wish i have more energy for packing and cleaning up.

Are you moving?

ye

08:30

pulling a 2500km move

08:31

probably just gonna ship everything back home

Oh wow, leaving China?

within china lmao

08:31

well road distance anyway

I sometimes forget how massive China is

I sometimes forget how far i am away from home

08:32

Learath2

I sometimes forget how massive China is

any idea how am I gonna ship 4 spinny harddrive home

TsFreddie

any idea how am I gonna ship 4 spinny harddrive home

Mh, I never trust anyone with my hard drives. Just so easy to break

08:34

If at all possible, take it with you

If it has to be shipped, I guess lots of bubble wrap

i imagine i have to take them off the chassis?

Followed by some less elastic padding, I prefer many layers of cotton

why haven't we got teleportation yet. i have too much stuff

TsFreddie

i imagine i have to take them off the chassis?

I would

maybe i'll ship the machine home and just carry the harddrives with me on the plane

08:36

When I was moving my desktop I pretty much just took all the pieces out and got a new case where I moved to

i would just sell everything

08:37

but i guess harddrives are different

TsFreddie

maybe i'll ship the machine home and just carry the harddrives with me on the plane

Gpu is another one to definitely remove

it's a nas, ain't got no GPU

08:37

That's good

i wish it did tho

08:38

kinda want to run some LLM

~~For transcoding the hentai~~ (edited)

Learath2

~~For transcoding the hentai~~ (edited)

well the iGPU can take care of that

08:38

also strikes are ~

Thanks boss

it is a commercial nas, just cause i'm lazy. it is quite under-powered and overpriced tho

Should I break US sanctions on China and bring you a 4090?

Learath2

Should I break US sanctions on China and bring you a 4090?

we can buy 4090 here

I guess someone already is breaking the sanctions, cool

i thought it was just banning busniess from collabroating?

08:41

iirc if you ban consumer trading you are gonna get kicked off UN or something

08:41

at least i think someone told me that's the reason why amazon and steam are still alive here

Hm, as far as I remember Nvidia was not allowed to export certain chips to China (and some other countries)

Learath2

I guess someone already is breaking the sanctions, cool

Just sell over a third party and a third country. As long as NVidia gets their money they won't brick the GPUs of their customers

nvidia is not allowed to, but e-commerce aren't nvidia that's what i'm thinking

TsFreddie

nvidia is not allowed to, but e-commerce aren't nvidia that's what i'm thinking

That could be it

well unless they just ban it from the customs side

08:45

or they just said that they would and nothing is passed yet

08:45

they do that a lot don't they

08:48

also huawei has 4nm chips and no one knows where they come from. which is kinda funny (edited)

TsFreddie

also huawei has 4nm chips and no one knows where they come from. which is kinda funny (edited)

As in no one knows who is selling it to them? This one should be easy enough to track down

Learath2

As in no one knows who is selling it to them? This one should be easy enough to track down

afaik, huawei don't say anything about them, china sure is not gonna investigate and us just don't know

08:50

it is probably just tsmc, but still. no one is 100% sure on that it seems for some reason

that would be wild

TSMC cancelled a lot of clients after that, but huawei still seems to have them

Well it seems to be just a Qualcomm Snapdragon 7. Qualcomm uses TSMC exclusively for their 4nm chips iirc

huawei is not using snapdragons tho

I guess the issue is that no one could figure out who the middleman is

TsFreddie

huawei is not using snapdragons tho

I assumed you were talking about this

Learath2

https://consumer.huawei.com/en/tablets/matepad-11-5-papermatte-edition/specs/

no

08:53

huawei has in-house chips made in 4nm

Wow, what do they use it in?

Mate60 Pro phone iirc

Well it just has to be coming out of TSMC, who else even has the capability?

08:56

Samsung maybe

there is a Kirin9000S soc, which is supposedly made by huawei's hisilicon chip design firm

08:57

but hisilicon doesn't list that one on their website

08:57

they only list the ones in 5nm

I wonder when SMIC will get to 4nm

SMIC has 5nm with VERY low yield i think

5nm you can still get acceptable yields without needing EUV

09:02

4nm as far as I recall is completely unfeasible

ye

09:03

it's definitely from outside, it's just weird that they can get them and get away with it (edited)

To be honest, it's quite impressive how far SMIC got with all the bans and sanctions

TsFreddie

it's definitely from outside, it's just weird that they can get them and get away with it (edited)

I'm surprised the US hasn't figured out yet. TSMC should know who they produced those chips for, no?

i imagine we just immediately dumped loads of resources on that area the moment the sanctions hit

Learath2

I'm surprised the US hasn't figured out yet. TSMC should know who they produced those chips for, no?

don't we all

09:05

i don't know anything about chip designs, can you just get arm cores and glue them without EUV

09:05

isn't SOCs just glued together arm core designs

Mhhh, I'm also a little weak on the chip stuff, but as far as I know the signaling requirements between the cores are beyond what you can achieve with "gluing them together"

i guess so

AMDs chiplet designs use a special protocol between the core groups to allow the slower signaling through pcb

maybe they just get them from other companies so TSMC really don't know. cuz UNISOC and xiaomi are still getting in-house chips from TSMC i think?

09:08

xiaomi is not using in-house chips at the moment but they are trying to

I've heard of the option of silicon interposers to patch together chiplets, that would be doable, but I remember yields being awful

also huawei just removed android from their product, which is really really weird to me

TsFreddie

maybe they just get them from other companies so TSMC really don't know. cuz UNISOC and xiaomi are still getting in-house chips from TSMC i think?

This would be my guess, but I'd also think the US would immediately figure it out in that case. Random Uzbek company ordering thousands of never before seen 4nm designs with no product to show for it

maybe huawei is just not selling much anyway

09:12

cuz even here, i would think a lot of people wouldn't go for huawei.

I wonder if anyone has confirmed that this chip is indeed novel

well maybe they do, but i think it'd be a hard sell after they ditched android

I've seen the scam of laser etching a different model number on the die before

Learath2

I've seen the scam of laser etching a different model number on the die before

that do happens A LOT here

It would be quite funny if this was just a snapdragon that has been re-etched

i should go pack some more stuff now

I should go shower, then go deposit some cash

09:20

Nvm, no hot water

09:24

you don't take cold shower?

TsFreddie

you don't take cold shower?

No I'm not a hustle culture influencer

i thought cold shower is just a white people thing

German government collapses after Olaf Scholz sacks finance minister

Unexpected move throws Europe’s largest economy into political disarray and is likely to lead to snap elections in March

wtf is going on over there

Lmao yeah he asked our president to kick out our finance minister

@Learath2 After 2 weeks of peeking at others code, I undertood that I've done a lot of horrible design decisions(not that I knew a lot about compilers xd), and now it's time to fix 'em all. The question now is what to feed to codegen, there're 2 options: 1) Symbol table & AST(as it is implemented now) 2) Lower AST to IR and don't pass symbol table IR will be referencing other elements so probably symbol table won't be needed, for example let a = 10; a + a; can be represented like:

IR {
    nodes:  [
       VarDecl {
           id: Id(1), // dis id is uniquely generated
           type_: Type::U8,
           name: "a"
       },
       Expr {
           op: Add,
           lhs: Id(1), // references the thing above
           rhs: Id(1),
       },
    ]
}

Which option do you think is better? :p

If you are going to an IR make sure you go to an SSA IR while at it, it'll make a lot of optimizations far easier in the feature when you decide you need them.
Embedding your symbol table into the IR is not going to change much, it'll just make it more annoying

14:27

nvm, do it correctly this time, you did the jank once

I still don't know what's the correct way, I just know that now it's trash xd

You usually want to go from the raw AST your parser generates, into something a little more friendly to optimization and code generation

14:30

Something like 3AC or an SSA form nowadays

where dooes type checking and name resolution happen?

You do that before you emit the IR usually

14:33

It can be helpful to actually have another IR in the middle that can help you with your typechecking

yep, that's what i thought about xd

Especially if there is a lot of syntactic sugar in your language that would make the original ast very annoying to work with

not now

14:37

Btw, I finally can use a vm, it was laggy as hell(maybe someone couldn't read qemu docs) before but after I installed virt-manager is works pretty nice

gcc e.g. has 3 different IRs and the AST

14:39

@MilkeeyCat btw you are getting to levels of compiler design that might benefit from looking at a book

do you know such books?

The classic is ofc the dragon book

However, if you want to learn about SSA forms and optimization, building an optimizing compiler is pretty readable

I saw comments on reddit which say that it's a bit outdated and no one makes compilers like dat nowadays

why are these all dragons

The issue is that I'm outdated and I make stuff no one makes

14:42

So my references are also outdated

I've heard good things about "Engineering a Compiler" but that's also rather old at this point

I also decided to make a kernel module xd

for easier codegen u want an IR thats made up of blocks
