WebM to MP4 using FFmpeg

This FFmpeg command converts a .webm video file to a standard .mp4 file using the libx264 codec for video, aac codec for audio, and a CRF value of 22. The preset is set to 'slow' for higher quality encoding, and the audio bitrate is set to 128 kbps.

If the input and output filenames don't contain spaces, quotation marks or other special characters:

ffmpeg -i input.webm -c:v libx264 -preset slow -crf 22 -c:a aac -b:a 128k output.mp4

Raspberry Pi Picoprobe Debug Setup/Tips & Tricks

This document details useful information on how to use a Raspberry Pi Pico as a SWD probe for another Pico using the Picoprobe software. This information assumes you have followed all of the steps in Appendix A of the Getting Started with Raspberry Pi Pico Guide and that you are doing development on a Linux system.

Essential Setup

Add the below files to your system to enable non-root access to the devices

/etc/udev/rules.d/99-openocd.rules:
```
# Raspberry Pi Picoprobe
```

	type Success<T> = {
	data: T;
	error: null;
	};

	type Failure<E> = {
	data: null;
	error: E;
	};
