Turns any terminal into a very useful way of writing code and scripts ~:whatchfile [file] [command] This will run the command every time the file is updated.

A large zero filled matrix is gradually filled with circles. Each circle is randomly drawn and adds a 1 to the matrix. The outlying random landscape looks quite natural. After a while, it seems very static, but before you realize it, it will completely change.

A bash based computational algorithm and protocol management tool. Very simple yet very useful. ~$cat commands.v function _01_firstStep { echo first step cp some files chmod 777 * } function _02_some_R_code { R –vanilla <<ENDOFRSCRIPT countdata = read.table(‘aligned/merged.counts’) countdata = round(countdata) write(countdata,”data.csv”) ENDOFRSCRIPT }   now to run any steps: ~:v command 01 | bash […]
