This post is about the ways we approached instrumentation, and some tools you can use to optimize your own apps (including code). Learn how we reduced CPU usage by 80% through Python profiling.
My first computer was a BBC Micro. It could do basic graphics at a resolution of 640×256 - with 8 different colours. Not a typo. Eight! The mono speaker produced bleeps and bloops. It was basic, in all senses of the word. Eventually, talented hackers found a way for it to do simplistic 3D graphics and even speech…
You'd think that given the same bytes of input you'd get the same bytes of output. lol. lmao. No, you don't. It's complicated.
