Gameclock is a fairly simple application designed to track the time spent thinking by the players during a chess game. Various clock engines are available (speed chess, fisher chess, board games, or hourglass). The graphical interface is keyboard-driven and is intended to be minimal and simple. The code is made to be extensible to other game types.
Screwdriver++ is a package with various tools for the C++ programmer in Unix environments. It contains classes for time measurement, image and file manipulation, and arbitrary precision arithmetics. Timer is a class for measuring time intervals with millisecond accuracy. Image is a class that uses OpenCv to manipulate images. File is a class to manipilate file input and output in various formats. Number is a class to manipulate arbitrary precision arithmetics.
Likwid is a set of easy to use command line tools for Linux. It supports programmers in developing high performance multi-threaded programs. "Likwid" stands for "Like I knew what I am doing". It contains the following tools: likwid-topology, which shows thread and cache topology; likwid-perfctr, which measures hardware performance counters on Intel and AMD processors; likwid-features, which shows and toggles hardware prefetch control bits on Intel Core 2 processors; likwid-pin, which pins a threaded application without touching its code (it supports pthreads, Intel OpenMP, and gcc OpenMP), likwid-powermeter which prints the Turbo mode steps and measures energy consumption on supported Intel processors, and likwid-bench, a low level benchmarking framework. It works with any standard Linux kernel. Likwid is lightweight and adds no overhead during measurements.
Publish is a relatively simple bash script for reducing the workload in the tasks related to publishing an image into a user's ~/public_html elsewhere via scp. Optionally, the script prints out the URL (preformatted for Web BBS use if so desired) coupled with most relevant EXIF information, does conversion operations, and adds an copyright notice.
clac (Command Line Advanced Calculator) evaluates mathematical expressions input via command line arguments or from stdin and writes the results to stdout. Unlike other command line calculators, clac has infix (natural order) expression syntax, is quite comfortable with complex numbers, defines a great many functions and constants by default, and allows easy definition of new user functions and constants using Python.
Seetxt is a lightweight text file and man page viewer for X windows. It maintains "document meta-data" for each user, allowing them to automatically keep bookmarks and highlights for read-only system files. It also has a "server mode" so that command line requests can be sent to a single running server rather than starting multiple instances. Other features include hypertext-style apropos (man page) searches, file monitoring, multi-level regular expression searching, a command history, and nice little toggle lights on the interface for the server and file monitor. There's also cross-application drag-n-drop support, and handy little features that allow you to view the output of shell commands and process the text buffer with an external command (sed, awk, grep, perl, etc.) Seetxt is POSIX compliant.
