A brief history of /proc

Those of you who have used a UNIX system before are probably familiar with the /proc filesystem. This directory provides a view of processes running on the system. Before getting into the gory details of the Solaris implementation (see proc(4) if you're curious), I thought I would go over some of the different variants over the years. You'll have to excuse any inaccuracies presented here; this is a rather quick blog entry that probably doesn't do the subject justice. Hopefully you'll be inspired to go investigate some of this on your own.more...

That's just the beginning, though. read more...

Perl wlan-ui

wlan-ui.pl is a program to connect to wireless networks. It can be run as a GUI which will offer a list of available networks to connect to.nstallation is simple and inelegant.

The system configuration file is different from the options configuration file (@configfile, above). The system configuration file tells the program how to configure the wireless interface, and the options configuration file sets defaults for access points and other things.

Reducing NumPy memory usage with lossless compression.

If you’re running into memory issues because your NumPy arrays are too large, one of the basic approaches to reducing memory usage is compression. By changing how you represent your data, you can reduce memory usage and shrink your array’s footprint—often without changing the bulk of your code. In this article we’ll cover:     * Reducing memory usage via smaller dtypes.     * Sparse arrays.     * Some situations where these solutions won’t work.
