Are you a hack programmer? Do you find yourself constantly Googling for how to do basic programing tasks?
Suppose you want to know how to format a date in bash. Why open your browser and read through blogs (risking major distraction) when you can simply stay in the console and ask howdoi:
$ howdoi format date bash
> DATE=`date +%Y-%m-%d`howdoi will answer all sorts of queries:
$ howdoi print stack trace python
> import traceback
>
> try:
> 1/0
> except:
> print '>>> traceback <<<'
> traceback.print_exc()
> print '>>> end of traceback <<<'
> traceback.print_exc()
$ howdoi convert mp4 to animated gif
> video=/path/to/video.avi
> outdir=/path/to/output.gif
> mplayer "$video" \
> -ao null \
> -ss "00:01:00" \ # starting point
> -endpos 10 \ # duration in second
> -vo gif89a:fps=13:output=$outdir \
> -vf scale=240:180
