What is a mutex? It's a binary semaphore which is a special case of the normal semaphore, which is a condition variable without the queue...

@code_star def neck beards and ppl hanging around unix and linux SE

Let's be honest. None of us knew what this did before LLMs. set -euo pipefail

@lemire “a wide margin”. Or 6-12 months behind which ain’t that wide.

China is promising to build a massive number of data centers. We all know what is happening: an arms race, not for stockpiling nuclear weapons, but for developing the smartest and fastest AI. You know who is winning by a wide margin right now? The USA. The race is not even close. Europe, Canada, the UK, and Japan are nowhere near what is happening in the USA. The limiting factor is power, electricity. China has been ramping up production and now generates more electricity per capita than Europe. The UK is heading for shortages. Historians will wonder how such advanced countries chose to sideline themselves from the 21st century by rationing energy. The game is not over. A country like Canada could still turn it around. But time is running out. Build!

@yacineMTB the proof is in the pudd.. pole

i actually can't believe i was the first person to solve 6 pendulum cartpole that's crazy

@lauriewired dang you say it like it’s a bad thing. And c++ devs just playing inside the compiler’s dev program

most non-C++ developers are just users playing inside a C++ dev’s program.

@collin_ruth89 10x better is wrong. Are you cooking food 10x faster, or does the food taste 10x better?

Do people actually buy electric stoves? Gas is 10x better. Someone explain this to me.

@davepl1968 gonna do something dumb like find the x,y of the center pixel and then four for loops where I draw up, left, down, right until fall off screen and always plus one to never blit the center.

I'm going to give you a computer science problem, covered by a software patent (US 4,197,590). Let's see if it's "obvious" to experts in the field. You're on a monochrome display. You want to draw a PLUS sign cursor, like in a paint program, leaving the pixel in the middle unchanged. How do you draw the vertical and horizontal lines without stomping on the center pixel? Do you save the center and put it back later? Or what's your solution? No sprites, of course, all done via Get/SetPixel(x,y) only. Assume something like bool GetPixel(uint x, uint y); void SetPixel(uint x, uint y, bool b);

@yacineMTB just buy a garbage bag of weed from a man on a barge and that barge weed is gonna be like ol times

Can you even buy shitty weed in Canada anymore? All of the stuff they sell now is literally crystal psilocybin

@brim006 tree company outfits hire quality control people who sample the planted blocks and if the trees are j rooted, bad density, wrong tree in thre wrong spot, then you have to replant the block. Also foresters check on the block throughout the years.

I always think about this guy and wonder about survival rates. I’m assuming he knows and has mastered the technique…but can you imagine if he finds out years later that nearly none of the trees he planted survived due to his fast planting technique 😭

@leostera 20 s compile/builds (C). 60s unittest. 20 min regression test. 5 min integration test. Don’t format.

random survey: are you on a >100k LOC codebase? how fast are your lints/format/build/test?

@EOEboh two ways to drive to the same store.

Explain the difference between: GET /products/99 GET /products?id=99 Same result. Different meaning Why does the distinction matter?

@yacineMTB you think John Carmack ever said this shit out loud even if it was true for him? If yr the best other people will say it for you.

I seriously might be one of the best programmers alive, if not the best programmer alive period

@tsoding driving on the wrong side of the road at night cause no one else is in the opposing lane kind of “safe”.

Average Rust dev: oh no buffer overflows are scary! >_< Average C dev:

@anuraggoel they want what we tell them rn and no branches implies no git so good luck to you cause rsync to push code is like a poor mans git.

AI is quietly deprecating GitHub. Agents do not need branches, PRs, or CI/CD rituals. They want to ship code straight to the cloud. The rsync renaissance is here. High availability. Zero bloat. Faster loops.

@ChShersh Program each phone app to poll your service every two seconds (lol) and if message then send it back.

Imagine everyone in the world has your app installed on their phone. How would you implement a system to deliver 8B+ notifications to everyone within 2 seconds?

@Adriksh ever tried autotools? Cmake is like a magic carpit over the tarpit

writing C++ is fine but configuring cmake is a genuinely traumatizing experience

@sudomateo we put up with a lot of smoking garbage as is tradition

You're telling me that we all just put up with Helm? I can see why I avoided using it for most of my career.

@yacineMTB march sun ottawa 🧑‍🍳

i don't feel exhausted anymore

@_trish_xD win32 C++. old school, crazy fucking fast, super light, windows only!

working on a client project: need to build a desktop admin panel. requirements: modern ui, decent performance (not crazy fast), but the deadline is tight. what stack would you choose if the goal is to ship as quickly as possible?

@thdxr frame this tweet. all timer

what if the models haven't actually improved for months what if we're all just getting dumber

@asaio87 this won’t age well

The sad thing about AI-generated code is that it can only get worse from here, not better.
