Although this guide still works and even works on Debian 13 it's deprecated.

It's replaced by this new guide which supports both 64-bit and 32-bit libraries.

I will keep it because the information here is useful.

How to install nvidia-legacy-340xx-driver on Debian 12 Bookworm

This guide will show you how to download, compile and install the nvidia-legacy-340xx-driver on Debian 12. Some people install the driver directly from sid but this will mix packages from both stable and unstable which may create issues. It's recommended to update and upgrade your system before you start.

Reading waveform data in ffmpeg

When working on an audio player, I wanted to extract the audio waveform data to paint the audio waveform dynamically in the browser on a <canvas> element.

Initially I used the bbc/audiowaveform package but this proved problematic for a number of reasons. First I wasn't able to install that package (or build the binary) in macOS for local dev. The other big issue is that I was only able to figure out how to install it on Ubuntu, so I couldn't use it in Alpine (for Docker images) or other environments like cloud functions.

Initial approach

I found out from these docs it's possible to paint a waveform with ffmpeg by extracting raw audio data:

	#!/usr/bin/env bash

	counter=1
	echo "demo: error state"
	while [ $counter -le 25 ]; do
	printf "\x1b]9;4;2;${counter}\x07"
	((counter++))
	sleep 0.1
	done
	echo "demo: normal state"

	"use client";
	import { useState, useEffect, useRef } from "react";

	function SimpleRecordButton() {
	const [isRecording, setIsRecording] = useState(false);
	const [audioStream, setAudioStream] = useState(null);
	const [mediaRecorder, setMediaRecorder] = useState(null);
	const [audioBlob, setAudioBlob] = useState(null);
	const [recordingTime, setRecordingTime] = useState(0);
	const timerRef = useRef(null);

	import MediaPlayer

	local wezterm = require 'wezterm'

	local themes = {}
	for k, _ in pairs(wezterm.get_builtin_color_schemes()) do
	table.insert(themes, k)
	end

	local fav_themes = {
	"SweetTerminal (Gogh)",
	"PaulMillr",
