astateful is a unique approach to Web development. It incorporates a solid theoretical foundation based on Dynamic Programming in which a Web site is programmed in such in a way that it can be "solved" using a 'top down' or 'bottom up' approach. It is very scalable. Caching and encryption are included by default. It has a steep learning curve.
iterate simply takes a command line with an inserted dollar sign, $, and substitutes $ with entries from a list. Each such inserted command line is executed sequentially. The list can either be specified in the command line or in a file. iterate is particularly useful in sending commands to clusters of nodes. It was written with SSH/plink in mind.
U++ is a C++ cross-platform rapid application development suite focused on programmers' productivity without sacrificing runtime performance. Based on strictly deterministic design, it provides a viable alternative to garbage-collected platforms, even for business logic oriented problems.
notification-thing is a full-featured implementation of the Desktop Notifications Specification. It is not tied to any specific desktop environment, and is focused on features like rate-limiting and flexible filtering to minimize distraction and noise ratio in a transparent way, without silently dropping anything ever.
"aura" is a desktop (X root window) background setter. It picks images randomly from specified paths, skipping those that are too small or have inappropriate aspect ratios, and rescales them by cropping solid margins, resizing with cubic interpolation and then the liquid rescale algorithm to fit the desktop with as little quality loss as possible. Images are labelled in the corner using embedded tags. It can changes images on a timed basis or when triggered by SIGHUP or the CLI, and tracks previous and blacklisted images.
BlockHosts is a script to record how many times a local system is attacked, based on configurable scanning of system logs for sshd or other services. When a particular IP address exceeds a configured number of failed login attempts, that IP address is blocked using hosts.allow files, or by using null-routing, or by using packet filtering. An email notification facility is also available.
