Load the Decompiled #BL602 #WiFi Functions into a spreadsheet ... For easier crunching
Google Sheets: https://docs.google.com/spreadsheets/d/1C_XmkH-ZSXz9-V2HsYBv7K1KRx3RF3-zsoJRLh1GwxI/edit?usp=sharing
Let's do Quantitative Analysis of the Decompiled #BL602 #WiFi Demo Firmware ... How many lines of code do we actually need to Reverse Engineer ... Now that we've found some matching source files?

Little #ffmpeg #bash #script I wrote to compress a video:
- makes videos very small in size, e.g. Tears of Steel 1080p - 704mb to 52mb 🚀
- automatically embeds subtitles into one file (no more carrying around .srt files)
- variable bitrate for both audio and video to deliver acceptable quality
- progressbar with remaining time etc.
- simple to use. just pass the file as param to compress
- if you don't like the default dimensions, edit the script

I've been thinking about making this for breakfast all night since @lupyuen posted his lunch!
It is a bagel with a tiny bit of butter, then a layer of hot pepper cheese, then blended garlic paste, then a second slice of hot pepper cheese, all topped with a sprinkling of potassium salt.
My god it was so much more glorious than it probably sounds!
