    If you disable paste in an input field, you should never be allowed to program anything ever again.

    Just going to point out: the UEFI BIOS spec is 2300 pages long, but somehow they couldn't manage to standardize on what key you would press to enter it.

    Me: "Delete this file." Windows: "Someone is using it." Me: "Who?" Windows: "I can't say." Me: "I checked using a utility. It says your file explorer is the one using it!" Windows: "Well, I had to show a preview." Me: "Why?" Windows: "Because you selected the file to delete it!"

    40 years of Windows versions and you still have to install a 3rd-party utility to tell you which program is preventing you from unmounting a volume :(

    If you thought software was bad today, buckle up, because it's about to get a whole lot worse.

    There's a new kind of coding I call "vibe coding", where you fully give in to the vibes, embrace exponentials, and forget that the code even exists. It's possible because the LLMs (e.g. Cursor Composer w Sonnet) are getting too good. Also I just talk to Composer with SuperWhisper

    "Really really smart people have a different opinion than I do, therefore they must be oblivious" is a bold take.

    Every time I see this kind of crap I want to know why there is a length limit on something you should never be transmitting or storing. Hashes don't get longer just because the input was longer. If you don't believe me, ask a cryptographer.

    Please stop creating microbenchmarks without analysis. If you haven't read the assembly for each run, you have no idea what you're actually benchmarking. This creates a lot of work for people like me who have to clean up the wave of misunderstandings. It is very frustrating.

    Check out the results for Levenshtein distance. Fortran out here impressing. I'd like to turn this repository into something special, with a wide variety of problems to solve with each language. If you have ideas, head on over and make issues / PRs!
