checkit is a file integrity tool that adds basic data assurance capabilities to file systems which support extended attributes. It allows you to detect any data integrity issues or file changes to any file. By storing a checksum as an extended attribute, checkit provides an efficient way to detect silent data corruption, bit rot, or other modification errors. It was inspired by the checksumming performed by filesystems like BTRFS and ZFS. Checkit allows similar functionality, the ability to compare stored files and entire directory trees against a checksum at a glance.
comedi2py feeds data from a data acquisition board into Python by using call-back functions. The goal was to make this as easy as possible, hiding all the complexity of the asynchronous acquisition in comedi2py and providing the Python program simply with an array of the sampled data at a given sampling rate. The program has been tested with the USB-DUX boards, but should also run with any other COMEDI supported data acquisition board.
comedirecord is an oscilloscope program to record data from a COMEDI-compatible device. Its philosophy is to save the data in its original unfiltered form but allow comfortable viewing of the data during an experiment. One can acquire data from multiple DAQ boards simultaneously, and also append data via an incoming TCP port, which could be a telnet connection into comedirecord or data from another program. Low-pass, high-pass, and notch filters can be switched on for each channel. A DC filter can be switched on, which is useful when observing small voltage changes at a high gain (for example, measuring small temperature changes). The output format is ASCII so that the data can be imported into GNUPLOT, scilab, or octave.
crunch/crnlib is a lossy texture compression tool and library for developers that distributes and uses content in the DXT1/5/N or 3DC/BC5 compressed mipmapped texture formats. crnlib can compress mipmapped 2D textures and cubemaps to .8-1.25 bits/texel, and normal maps to 1.75-2 bits/texel. crnlib's quality and performance is competitive to transform-based solutions, or other offline/real-time DXTn compressors such as squish or ATI_Compress. crnlib implements a new form of "clustered" DXTn compression, with a compressed texture data format that was carefully designed to be very quickly transcodable directly to raw DXTn texture bits with no intermediate recompression step or individual pixel-level operations. The typical single threaded transcode to DXTn rate is equivalent to 100-250 megatexels/sec. Fast random access to individual mipmap levels is supported.
csv2html is a command line utility and reusable Python module that convert CSV files into HTML tables and full HTML documents. They can use either the old school HTMLgen module or the more modern HTML module (both for Python 2.x), and offer a wide range of options for formatting the output.
delaboratory is an image postprocessing application. It allows you to modify the color and contrast of a photo in a creative way, using curves, a channel mixer, an equalizer, blur, an unsharp mask, high pass, vignette, dodge/burn, shadows/highlights, and blending in different colorspaces (sRGB, ProPhoto, LAB, CMYK, LCH, HSV, HSL) with floating-point precision. Each operation is stored as an adjustment layer, and you can watch a realtime preview.
