Migrating VHS using Canopus Firewire in Fedora

My notes around migrating analog VHS tapes to digital files using the Canopus ADVC55 IEEE1394 firewire hardware device in Fedora.

Hardware

I can't find this hardware online much anymore, but it works with a PCIe Firewire card. The VHS player outputs to it, it uses an FPGA to play the raw video through firewire to Linux. Ensure you have a green light on the device when playing the VHS tape.

Capturing to raw file

I prefer to capture using uncompressed, unaltered format so that if there's a better codec or format later in time, I can use it. This way I keep the original source material (with no quality loss), even though it does take up a huge amount of disk space.

My hundred struggles while using Linux as my desktop driver (Ubuntu 24.04)

Hi! On Thursday 25 April 2021, I entirely switched from macOS to Linux: https://maelvls.dev/evolution-of-my-home-office/. I took note of every adjustment I had to make along the way. I use Ubuntu "vanilla" (with Gnome as my desktop manager).

🔥 Update 26 June 2023: I am abandoning "desktop" Linux! I can't bear having to work around everything all the time, not even counting the tons of problems that occur whenever I do a major version upgrade (e.g., when I upgraded from 21.10 to 22.04, my PPAs broken obviously, and also I lost all the hack I had made to the /etc to work around problems). I am officially back to macOS starting 26 June 2023. I'll still use my Linux workstation remotely over Mosh, but not as a desktop environment.

Running games through Steam's Proton is great. But what if there is a secondary exe or configuration application bundled with the game? How can you launch it if Steam itself only launches the game?

Simply run this command in a terminal:

cd /path/to/steam/steamapps/compatdata/20920/pfx

STEAM_COMPAT_DATA_PATH="/path/to/steam/steamapps/compatdata/20920" WINEPREFIX=$PWD \
    "$HOME/.steam/root/steamapps/common/Proton 5.0/proton" run ./drive_c/path/to/custom_application.exe

True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.

Building and using mesa for development and testing

This explains how to build mesa from source, and how to use the custom built mesa to run some apps and games, without needing to replace the mesa libraries that your operating system runs on.

Let's assume that you are using an x86_64 system.
