Ackr is a very small subset of grep/ack/rak, for lazy developers. grep is a great tool, a very powerful tool, but often too powerful for simple needs. Ackr looks for a search string in all text files and in all subfolders from the working directory, is case insensitive, has no options, doesn't look into hidden folders/files, and displays the search term in a bold font.
animbar lets you easily create your own animation on paper and transparancy. From a set of input images, two output images are computed that are printed, one on paper and one on transparency. By moving the transparency over the paper, a fascinating animation effect is created. This animation technique has been known for hundreds of years under names such as picket fence animation, barrier grid animation, and others.
cipra is a simple, TAP-compatible Unit Testing Framework for C++. It's written in 100% standard C++11 and is only a couple of header files, making it easy to include in your C++11 project. TAP, the Test Anything Protocol, is a standard output format for software unit test frameworks which was originally designed for Perl, but can serve other languages. It has a rich number of tools ("harnesses") which parse TAP-formatted output and do useful things with it. TAP, however, is equally human-readable. The name cipra (pronounced /ˈʃi.pɾaː/ "SHEE-prah") comes from the lojban phrase "lo cipra", which means "the test". It is properly written with an initial minuscule "c", even when at the start of a sentence.
ddrescueview is a small tool that allows the user to graphically examine ddrescue's log files in a user-friendly GUI application. The Main window displays a block grid with each block's color representing the block types it contains. Many people know this type of view from defragmentation programs. The program is written in Object Pascal using the Lazarus IDE. It can be compiled to run on Windows, GNU/Linux, and probably OS X too. The downloads include binaries for the respective target platform and the project files (source code).
foo2hbpl is an open source printer driver for printers that use the HBPL version 2 wire protocol for their print data, such as the Dell 1355, Fuji Xerox DocuPrint CM205, or the Xerox WorkCentre 6015. These printers are often erroneously referred to as winprinters or GDI printers. However, Microsoft GDI only mandates the API between an application and the printer driver, not the protocol on the wire between the printer driver and the printer. In fact, HBPL printers are raster printers that happen to use a very efficient wire protocol. HBPL is just one of many wire protocols that are in use today, such as Postscript, PCL, Epson, ZjStream, etc. This driver uses Ghostscript to perform all of the heavy lifting (image processing). There are five major components to the foo2hbpl printer driver: foo2hbpl2 (the page image to protocol conversion engine of the driver); foo2hbpl2-wrapper (a shell script (compatible with foomatic) that runs ghostscript and foo2hbpl in a pipeline); icc2ps (converts an ICM color profile to a Postscript CRD, which is then fed into Ghostscript before the users Postscript program); foomatic-db (foomatic database entries that describe the supported printers and their options so that printer spoolers know how to access the printer using foo2hbpl2-wrapper); and hbpldecode (a tool for developers to inspect HBPL streams).
