 Monitor files while developing to restart Processing sketch on save with `entr`. After running the sketch in one terminal with `processing-runsketch_IF3.sh`, in another terminal run something like 
 ```
-ls PROJECTS/IF3Si/pde/IF3Si/*.pde | entr killall /home/random/src/processing-2.2.1/java/bin/java
+ls PROJECTS/IF3Si/pde/IF3Si/*.pde | entr killall java
 ```
+(this will kill other running instances of java, so beware)
