Debunking the myth that rust is "just as fast as C"
Readers added context they thought people might want to know
Rust: naive recursive Fibonacci in unoptimized debug build (cargo run). C: Binet formula with -O3. Different algos and opts; not a fair language comparison. doc.rust-lang.org/cargo/referenc… nnethercote.github.io/perf-book/buil…

From what I see here, y'all started to prefer pooping code without steering, like if there is no tomorrow. Thanks to this, setting up a more conservative, discussion-based workflow became very painful with today's harnesses.

I can't count the number of markdown files I had to edit just to state that a question or a problem statement is no greenlight to edit stuff.

So much irony of how the most corrupt bunch of Hungarian politicians and oligarchs are seeking shelter (and looking for jobs) in the US, in MAGA circles. These are people who are know nothing else than how to thrive in corrupt systems. And how to build such systems.

Viktor Orbán heads to the US in June, where family members already live, while loyalists seek MAGA think-tank jobs and visas after the election defeat. Meanwhile, oligarchs & cronies are shifting wealth abroad, largely to the Middle East. @floragaramvolgy theguardian.com/world/2026/a…

Orbán's 16 year experiment with right-wing authoritarianism didn't bring anything but incompetence and corruption. In the end, it was the election system they built that backfired on them. Congrats Hungary, we made it through!

@GergelyOroszApr 12
Hungary, in the end, chose Europe, rejected Russia, and rejected sprawling corruption. With record turnout (78% of those eligible voting), Tisza gained supermajority. Orbán’s autocratic regime, built out, step by step, over 16 years, will promptly be dismantled. Historic!

yes, the AI gold rush is turning the industry's approach to QA upside-down. there will be even more fake "coverage" contributed only to improve metrics

I see a lot of "I never used to write tests but not I just tell LLM to generate a full suit". But isn't this wrong? Thinking from first principles, if tests are definitive proof that your code works then you should put a lot of manual effort into designing good test suit, and then just let LLM oneshot the actual code to satisfy the tests. Why the common practice is the other way around? Is seems that in theory TDD should thrive in agentic-first coding, but it not. Why?

"They declare a struct which uses a single object reference for storing its Value, which means: Boxing" 😮‍💨

We merged an early C# 15 preview feature into .NET 11 preview 3: unions. Adds union declarations (`union Pet(Cat, Dog, Bird) { ... }`) and union types (attributed with `[Union]`). They can be treated by pattern matching/switch expressions as a closed set for exhaustiveness.

Two ways to use ChatGPT if you don't know something: 1. You ask and learn how things work. You know how to do new things yourself. 2. You tell ChatGPT to do it for you. You learn nothing. Two different self-feeding paths: Iterative self learning vs stuck in the bottom.

I keep being amused that Microsoft decided to leave GitHub without a CEO and independence - playing reorg games instead of reinventing themselves - right when GitHub would desperately need to. AI makes existing workflows useless. All set for a startup to take on GitHub

I’m not afraid. I’ve been dead for 47 years this is the voice of a woman in Iran who is fed up with the Islamic republic. 47 years ago, the Islamic Republic took our rights and turned a nation into hostages. Today people have nothing left to lose, they rise. Iran is rising.

Every time Microsoft or Google employee tweets about "wow AI writes 90% of my code, so amazing". Don't worry, we've noticed. Good luck with the next layoffs round!

If you’re protesting against a war and holding up a picture of the guy responsible for the repression, murder, and execution of Iranian children and people, you’re not an ally to Iranians and their fight for freedom. Imploring you all to research this man & not glorify him.
