bash: give yourself useful recent directories with `cd` and `d` commands
Recommend to add aliases in `~/.bashrc` to use this scripts. For example:
alias cd='. ~/bin/cd-pushd.sh'
alias d='. ~/bin/dirs-good'
Causes, for example:
$ d 0 ~/bin
1 ~
2 /srv/www/project/ ... /long-directory-name

DAG visualization

taken from https://github.com/bobbydavid/dag-visualization at 6/22/13.

The algorithm is:

Create a random DAG (topographically sorted).

Determine X-positions. For each node, find it's minimum X-position. Then, in reverse order, find the maximum X-position of nodes that can be moved forward.

Determine Y-positions. For each node, place it as near as possible to the mean Y-position of its parents. Give preference to placing nodes that have a single parent with a single child (a 1-1 relationship), so that these will always be shown in a straight line.
