oelna / bingo.php
Last active Oct 9, 2019
A generator for unique Bingo cards in PHP. See in action (generates cards printable on A4 paper size)
View bingo.php
Generate however many unique bingo cards you require (should be fewer than 10k though).
This is not meant to compute ALL possible bingo cards, obviously, but to help set up a
nice amount of cards for play.
If you require a free space somewhere on the board, you should probably tweak the output,
not the generator.
I wrote this because existing solutions on stackoverflow were in languages I could not
test as easily and many existing generator websites generate crap cards that do not
adhere to the bingo number distribution in the 5 rows, so you spend an eternity looking

Clean an iTunes M4A audio track from all identifying/personal information with AtomicParsley and Python

What is this

This python script is a radical attempt to remove all personal information from iTunes M4A audio tracks. All ID3 information will be lost in the process, sadly. You need to figure out a special offset in one of your audio files in a hex editor for this to work. If you are looking for a very simple solution, this is not your script.

If this helps you, please consider tipping to make up for the ridiculous amount of time I lost putting this together:

This code is based heavily on the instructions given on
Many hours on Stackoverflow have been spent trying to make this.
I tried to clean it up, make it readable, add a nicer UI and feedback about errors.
If you like this, use this or it helps you, I'm happy to hear about it.
Drop me a line if you have feedback, too.
