Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

This information applies to the PICO-8 0.1.6 release.

This document is here to help folks with a proficiency in Lua understand the limitations and discrepencies between Lua and PICO-8's Lua.

You can always view the manual or yellowafterlife's extended 0.1.1 manual.

General

anything written in uppercase the PICO-8 editor or .p8 is made lowercase by the editor. → editing the .p8 file directly can work
print(function() end) outputs the string function instead of the string function: 0x0000000.
