  • Why I switched to NixOS (And why you should, too) - Márcio Sobel

    Jump

  • I am a nixos fan, I do tell people to use nixos, but for some reason all these switch to nixos posts feel sus. Idk.

  • How would you design parallel grep for huge JSONL files?

    Jump

  • If you're writing a program, definitely multiple threads or processes that each scan a chunk of the file, which basically means seek to the start of the chunk, read lines into the scan code until you hit the end of the chunk. For jsonl each chunk will need an alignment step to not break the jsonl.

    For command line trickery, maybe the file could be chunked up by running multiple dd instances with an offset parameter piped into grep. This has many synchronization issues and all the outputs should be captured separately then combined afterwards. I can't think of a good way to align this method to line edges but maybe you can put some fancy regular expression magic into the grep step to ignore malformed json at the beginning and end and overlap the chunks?

    Grep is fast already, maybe test the simple approach and see how long it takes.

  • Local LLMs and learning CUDA on a machine with 6 1070Ti GPUs... Some of it works out of the box... For other stuff I'm having to explore what will work on the sm61 cuda architecture.

    Also getting better at running a pair of old 3d printers.

    I'm not one to buy new hardware if you can't tell :P

  • I wouldn't say it's the only sane way, but it's certainly my favorite

  • I think nix just has name recognition, that's why I use nixos not guix :/

    Guix really should be called Gnuix, maybe that name was already taken.

    Why does this website feel like the end of FOSS?

    Jump

  • Wait, this makes no sense. Just ask your AI to write the libraries you need rather than clone an existing project

  • Can you touch type?

    Jump

  • I didn't learn to touch type until I overpaid for a keyboard with blank keycaps. I didn't make much of an effort other than struggling to type without a way to check what keys I was about to press, but it seems to have mostly worked. As a consequence I never learned dvorak because qwerty was tough enough, maybe next month I'll switch 😅

    My typing speed feels faster but it's probably not great for things I don't normally type, plus I haven't measured it

  • Nowhere, but I've bought prints locally that are really nice that come from people on patreon... Lol but I forgot the names :(

  • Any idea what is this community about?

    Jump

  • It's a time proof blockchain system that allows submissions to be incorporated into a block and then after the block is published users can prove that they submitted whatever before a certain time I think. Worth a block IMHO.

  • Designed a simple photo frame on FreeCad. Why are some layers peeling in my print?

    Jump

  • Hopefully this isn't a common problem, but I was running auto bed leveling manually, the getting failed prints because I didn't save the levelling results to the printer and I didn't have gcode to load the levelling data and enable it in my slicer settings.

    Maybe something similar is happening to you.

    You can also try disabling auto leveling and level manually, that was giving me better prints for a while but it's a pain.

  • Where is Linux not working well in your daily usage? Share your pain points as of 2026, so we can respectfully discuss

    Jump

  • I have the same problem with nixos. It's partially solved but some plugin derivations are behind the times or something (or maybe I'm the problem and I can blame documentation :P)
