  Convert a video file (e.g. from https://losslesscut.app/) to gif, downscaling & using only every 4th frame: ```bash ffmpeg -i in.webm -vf "scale=384:216,setsar=1:1,select='not(mod(n,4))'" out.gif ``` - 384:216 → the new size ` #Bash #Linux #ffmpeg #gifmaking #fandom

  Solved sekrets management for my budding NixOS pi application cluster (kinda :P)! In this case, it's transcrypt to the rescue: https://github.com/elasticdog/transcrypt ....I really should have initialised it in aes-256-ctr instead of the aes-256-cbc default tho....... But yeah, transcrypt + git submodules = I can open source my NixOS config in the future! #NixOS #transcrypt #git #sysadmin #SecretsManagement #terminal #RaspberryPi

  Useful character: the unicode zero width space '​'. Ever wanted to @​mention someone without pinging them, but felt awkward doing the space thing ala @ mention?

  @sbrl's 2 laws of artificial intelligence: 1. AI will always hallucinatinate 2. AI will always be biased AI is like a dictionary. It stores the important things in the training dataset in its memory. Then it matches against them when queried. Anything outside of what it learnt matches results in an inaccurate answer. Data is generated by humans, who are inherently biased. We can't account for biases we don't know about. What matters is not really AGI and media hype, b...

  `lnav` is a fab tool for analysing logs. Today I used it for debugging a verbose `strace -f` log file to analyse what the problem was w/smth and it was cool Tip: hit `<tab>` to edit, enable, and disable existing text filters added w/e.g. `:filter-in` and `:filter-out`. #lnav #Linux #Logs #strace #debugging #ArchLinux #Tools #DebuggingTools #Sysadmin #CommandLine

  I have hyprland on my lab pc (considering a switch to niri), and just had a situation in which I couldn't get gamepads to work no matter what I did. Solution: make sure I had the `input` group so I had permission to access `/dev/input/*`...... * facepalms * 🤦‍♀️ #Linux #LinuxDesktop #hyprland #gamepad #ds4 #debugging #DebuggingMonday #ExceptItsThursday

  Reminder system, component #381.6: https://starbeamrainbowlabs.com/msg.html By writing a message and using the *send tab to device feature*, I can send myself little messages I know I'll see when I sit down at that target device.
