@cmuratori @fernandp maybe put that code in a separate compilation unit and use that flag can work?

@fernandp "Selectively" being the key here :) I agree you can turn it off for an entire CU.

Is there any way to selectively disable SLP in CLANG? It seems to really really want to SLP even when you disable vectorization for a loop:

@ID_AA_Carmack perhaps you can DIY speakers by connecting wired speakers to an SBC to use WiFi instead of BT.
or maybe there are commercial speakers that support WiFi.
English
When you stream Spotify to Bluetooth speakers or headphones, the audio comes over the network lossily compressed with Vorbis or AAC codecs, is then decoded on your device to 48 Khz raw samples, then the Bluetooth stack lossily re-compresses it with SBC or AAC codecs before sending it over the airwaves to the speakers.
I don’t have “golden ears” to pick apart audio quality like I can with, say, missing gamma correction on texture filtering, but that still hurts my system optimization soul. It is likely over-optimization, but It would be cleaner if there were a way to send bluetooth-ready, compressed audio directly.

@Love2Code i wonder if 3D modeling non basic shapes (humans, monsters, etc) with SDF isn't practical

I'm building a toy game engine based on Signed Distance Fields (SDFs), inspired by Mike Turitzin! 🔧

@Adriksh give Premake a try.
i wrote Premake generators and a concise guide for using them with vscode and clangd: virhex.com/a/vscode-prema…

How do you teach programming in 2026?
I have been teaching programming professionally for two decades.
It doesn’t work anymore.
I now consistently catch students who produced good software during a 15-week course be unable to write a simple loop at the end of the course.
« Just forbid AI. »
You can’t put someone in a cage for 100 hours and force them to program without AI.
We need to change the whole approach. Maybe go AI first. 🤖
This means MUCH harder homeworks.

@Love2Code please compress the video video a little more i can almost make out a single letter
English
I think I found a faster, recursive algorithm to render Signed Distance Fields (SDFs) more efficiently using less samples. Here's a video with a short explanation. As far as I know this is novel? Curious to hear your questions/feedback.

@Enhex @lauriewired @AgustinLebron3 I don't know C++ (apart from the basics).
But all of the experienced, productive developers who are well versed in C++ and some other languages unequivocally tell that C++ is a broken retarded shit.
One of there friends wrote a book on UBs in C++.
English
C++23 is the answer to the question:
"What if you put nice features in a language, but did them in the ugliest conceivable syntax? You know, because of backward compatibility or something."
English
@lauriewired @AgustinLebron3 i never heard a concrete real example for something bad in C++ from its haters.
vast majority of them are parroting "C++ bad".

I think flat_map was a very nice addition. More cache friendly map option. Personally I think it's very nice that the syntax is still the same as all the other containers.
I basically don't have to learn new syntax to be able to add the latest and greatest containers to my repertoire

@wookash_podcast It's been 1-3 years since people have been saying this stuff. If they have 10x'd their productivity, that is 10-30 years in traditional developer time. Where is all the softwares that should have been produced by this massive productivity increase?

It kinda feels like "everyone else on twitter" might not be perfectly honest with their results

Alright interns, we need to have some real talk here I am tired of vibing on stream. I dont really like vibe coding unless its a tool i have no desire to build (how i manage things on my stream / how i write my youtube videos are great examples of things i would never build but i have). I dont like vibing the things i care about. I hate the code it generates, i hate the feeling of getting everything i ask for and nothing i want. I hate the subtle offness around vibe coded things. It is just driving me nuts. So for the next while i am going to be done vibing on stream. I genuinely have been trying my hardest to make this work and i cannot quite put a finger on why i hate it, but i do. And i just feel so horribly guilty and wrong because i am not getting the results of "everyone else on twitter." How am i, someone who prides themselves on making youtube videos that i think are actually good for people. To make videos that help people laugh at the silliness of tech or learn something new. But here i am not able to keep up with all these people claiming the sky is literally coming down. I just feel horrible and guilty about it. Now i know the world is changing fast, and i want to be able to understand that change super well, be able to talk about it, be able to give really accurate opinions about it so for the last 3 months i have vibe coded an absurd amount of things. But now... i am just tired of it. I dont want this any more. I want to be a tradcoder. I dont know why i told everyone this, but i just have this growing sickness that is just eating me alive around vibing and i dont know how to express it. You all are fired, CEO ThePrimeagen

@ForrestTheWoods be the change you want to see in the world.
shouldn't be too much work i assume.

Are there any doc generators for C++ that are absolute garbage?
I hate Doxygen with a firey passion. The comment syntax is bloated crap. The website is ugly garbage.
RustDoc is great. I want that for C++. And also Python.
That seems like a reasonable ask! Suggestions?
English
@Pretentious_A_ @midnucas @lauriewired @ChShersh well if you actually want multiple instructions then reusing a register with them without loading a new value to it qualifies as single data.
English
SIMD actually means “Single Instruction Multiple Data”???
It all makes sense now.
English
@midnucas @lauriewired @ChShersh you can categorize instructions that do multiple operations like fused multiply add and passing the same variable in multiple operands as multiple instructions single data
English
@lauriewired @ChShersh Are there any MISD systems?
English
definitely not a misleading graph

@ChristerEricson even if it works keep in mind when you're using it you're sending your code to the biggest copyright infringers in history.

The best programmers I know swear that Claude Code et al have transformed how they code. Tests + prompting is key. I 100% believe them.
But: does it work cuz they’re super engineers, who prompt towards proper architecture and solutions?
Can lessers guide AI as good as them?

Wow, this is probably the most eye-opening chart you will see today. With profound consequences for our societies, future and prosperity.
Can someone please explain how this happened?

why is the mouse industry so fucked up?
why can't I find a mouse that:
- does not look like a RGB gaming rig
- doesn't have a ton of buttons on it
- is wireless
- has a good build quality which doesn't have a scroll wheel that dies within 2 months
- is not MX Master
