I’m usually an avid fanboy of Qt, but the more I use it, the more I find myself wanting two changes: 1. More slots please 2. More control over signalsÂ Read on forÂ a couple examples.
The GNU crew improved Make with lots of handy stuff. One such gem that I found today is the ?= operator, which only defines a macro if it is not already defined (like as an environment variable).
