Find wasted disk space with the Agedu Unix utility

vote

agedu scans a directory tree and produces reports about how much disk space is used in each directory and subdirectory, and also how that usage of disk space corresponds to files with last-access times a long time ago.
In other words, agedu is a tool you might use to help you free up disk space. It lets you see which directories are taking up the most space, as du does; but unlike du, it also distinguishes between large collections of data which are still in use and ones which have not been accessed in months or years – for instance, large archives downloaded, unpacked, used once, and never cleaned up. Where du helps you find what's using your disk space, agedu helps you find what's wasting your disk space. read more...

Run Unity desktop on Linux Mint 12

vote

The combination of GNOME 3 and MGSE is an attempted to improve on the user-experience of a stock GNOME 3 installation, however, it still leaves the user fighting the desktop just to get things done, and MATE is not yet ready for prime time.

sslh – ssl/ssh multiplexer

sslh accepts connections on specified ports, and forwards them further based on tests performed on the first data packet sent by the remote client.Probes for HTTP, SSL, SSH, OpenVPN, tinc, XMPP are implemented, and any other protocol that can be tested using a regular expression, can be recognised. A typical use case is to allow serving several services on port 443 (e.g. to connect to ssh from inside a corporate firewall, which almost never block port 443) while still serving HTTPS on that port. read more...

Currency Traders on Raspberry Pi

vote

You can now run Currency Traders on your Raspberry Pi. It is extremely efficient and takes only about 2.2% of the memory of a 512MB RPi and less than 0.5% of the CPU. More CPU will be consumed when players are online, of course, but it should support up to a hundred or so concurrent players on a normally clocked Pi.

The installation is four quick steps, described in the readme.txt file. The entire system is a single binary, available either dynamically linked or statically linked. The static version should work on most any Pi running most any Linux. The dynamically-linked version was compiled and tested on Raspbian Wheezy and may work without library fiddling on other Pi Linuxes.

Scroll to the bottom of the TEOTWAWKIgames.com page for the Raspberry Pi download links.
