The idea is that they will take all the pain away when it comes to keeping the big bad entropy out of the picture so that you can focus on the business side of things.

ESP01S: Teething pain…

Recently I have picked up few ESP01s boards as an addition to my IoT Platform arsenal (Arduino is kinda nailed 101% at the moment). However regardless what I did (and I did read quite a few tutorials) that thing did not want to output any meaningful serial information nor it was going to connect to a wifi network...

Compression idea thingy

Super basics of the Huffman compression algorithm (do more research if this sparks your interest). Lets say that we have a string of characters: 012102 Now lets do a simple mapping of characters to bits, 0 = 0
1 = 10
2 = 11 So the above string would end up looking like this in binary: 0101110011 Once we got that lets have a quick think about how many bits it takes to represent our string: 10 (bits) / 6 (characters) = 1.666 bits per character.
