  • Badabinski@kbin.earthtoTechnology@lemmy.world•Shell Tricks That Actually Make Life Easier (And Save Your Sanity)
    8 days

    set -e: Exit on error. Very useful, but notoriously weird with edge cases (especially inside conditionals like if statements, while loops, and pipelines). Don’t rely on it blindly as it can create false confidence. (Pro-tip: consider set -euo pipefail for a more robust safety net, but learn its caveats first.)

    while I appreciate that the author mentions how weird this is, nobody is going to learn all the caveats correctly. Don’t use set -e. Don’t use set -e. Don’t use set -e. It’s a shit ass broken ass fucked feature that half of nobody understands well. Here’s a great wiki page explaining why it’s trash: https://mywiki.wooledge.org/BashFAQ/105

    People like Go, and Go requires you to manually and stupidly handle every possible error case. Why not do the same for shell? It’s really quite easy:

    #!/usr/bin/env bash
echoerr() { echo "$@" 1>&2; }

die() {
  message="$1"; shift
  exit_code="${1:-1}"
  echoerr "$message"
  exit "$exit_code"
}

temp_dir="$HOME/tmp"
mkdir -p "$temp_dir" || die "Failed to make persistent temporary dir $temp_dir"
lc_dir="$(mktemp -d -p "$temp_dir")" || die "Failed to make target dir in $temp_dir"

    Look at that, descriptive error messages! And it doesn’t depend on a shell feature that is inconsistent between versions with no good documentation about all of the fucked up caveats.

  • Badabinski@kbin.earthtoLinux@lemmy.ml•What's a Linux distro thats breaks the windows mold and is good for testing?
    2 months

    If you want extreme flexibility, use Arch Linux, since it makes it trivial to swap out which window manager you’re using. It sounds like you’re familiar with Linux at this point, so you probably have the requisite knowledge to give Arch a spin.

    Niri is supposed to be a pretty interesting WM if you’re looking for something new. I’d be interested to hear why i3 was too much, since I found it to be pretty smooth to pick up.

  • Badabinski@kbin.earthto3DPrinting@lemmy.world•Does Prusas textured sheet...work at all?
    3 months

    I use a textured sheet for all of my Prusament PLA prints on my Core One and XL, and it’s never given me a hint of trouble. I’m using the Prusa-provided profiles with zero tweaks.

    I just hit it with a bunch of 99% IPA while it’s cold and scrub it with paper towels before every single print. I don’t heat it up until all of the IPA has dissolved, since apparently PEI is incompatible with hot IPA. I’ve never washed my sheets with soap, I’ve never applied any sort of bonding agents to them, and I’ve never sanded them.

    Maybe you just have a bad print sheet?
