Nmond is a Ncurses based system performance monitor for Darwin (Mac OS X) written in pure C which was "forked" from nmon. The original nmon gathered system statistics by looking at /proc, which is not available on Darwin, so I had to implement system calls for all the statistics. The original program was monolithic and used global state a lot; it was modularized during the rewrite.

Here are some apps for OS X, iOS, or the web which I voluntarily use frequently enough that I would be willing to recommend them to other people.
Securely store passwords and keeps them synced across devices.
I am always in a terminal window, and I usually have more than one open. Tabs are nice for this, but panes are even better. Sure, I could open a single terminal and then use tmux, but I've never got into that habit. As an added benefit, iTerm2 can send keyboard input to multiple panes, which is super slick.
This is currently my favorite general purpose text editor. I started using it because it could quickly open and replace text in very large files. I kept using it because it makes navigating to files and sections within files quick (CMD-p to fuzy search file names, CMD-p then @ to search within the current open file) and it makes editing multiple lines at once very easy (columnar editing or at arbitrary locations with the CMD-d hotkey); for some text manipulation tasks this has replaced using small command line scripts. As an added bonus, it is also available on Windows (in addition to OS X and Linux), and the license is cross-platform. There are some very good text editors out there, but when you code for a living you should buy the best.
Here are the plugins I frequently use:
This is a tool which locally centralizes developer documentation. I use it all the time when I am developing.
This is my tool of choice for creating and managing websites. I have been using it for quite some time, and when I started using Coda it was without a doubt the best tool for this job. Since then other tools have came out which are very competitive, but I continue to use Coda; it is intuitive to use and, most importantly, reliable.
This app gives very good hyper-local, short-range weather forecasts. Do I pack up and go home or stay and wait out the storm? This app has helped me choose wisely many times.
