Created April 12, 2026 18:03
Formula to calculate fee coverage for Paddle for a given subtotal and VAT percentage. Also takes a source and target currency to add fee conversion fees. The source currency is the buyer currency, the target currency is your account balance currency. Note that with a payout, if your bank account's currency is different from your Paddle account c…

Generate compile_commands.json automatically for clangd with CMake
# Automatically create and update a symlink to the compile_commands.json file in
# the source directory, so that it is in a known location and can be picked up
# easily by clangd. When using Visual Studio Code, use the clangd extension,
# version 0.3.2 or higher, so the clangd language server automatically restarts
# on configuration change, which is useful when switching between Debug and
# Release builds (to switch between debugging and testing performance). See
# https://github.com/clangd/vscode-clangd/issues/300. Always build the "ALL"
# target during development, to ensure the compile_commands.json is in sync.

Regulate your screen brightness live with a simple zenity slider. Made this script because the built-in slider in Manjaro's task bar doesn't work on my older iMac and I don't want to put too much effort into fixing it. Based on this script: https://gist.github.com/ViktorNova/a13c6613dd365b2c67b0 NOTE: Check line 60 for window positioning
