 zfp is a compressed format for representing multidimensional floating-point and integer arrays. zfp provides compressed-array classes that support high throughput read and write random access to individual array elements. zfp also supports serial and parallel (OpenMP and CUDA) compression of whole arrays, e.g., for applications that read and write large data sets to and from disk.
 
 zfp uses lossy but optionally error-bounded compression to achieve high compression ratios. Bit-for-bit lossless compression is also possible through one of zfp's compression modes. zfp works best for 2D, 3D, and 4D arrays that exhibit spatial correlation, such as continuous fields from physics simulations, natural images, regularly sampled terrain surfaces, etc. zfp compression of 1D arrays is possible but generally discouraged.

 SIONlib is a library for writing and reading data from several thousands of parallel tasks into/from one or a small number of physical files. Only the open and close functions are collective while file access can be performed independently.
 
 SIONlib can be used as a replacement for standard I/O APIs (e.g. POSIX) that are used to access distinct files from every parallel process. SIONlib will bundle the data into one or few files in a coordinated fashion in order to sidestep sequentialising mechanism in the file system. At the same time, the task-per-file picture is maintained for the application, every process has access to its logical file only. File access is performed using SIONlib equivalents to standard C-I/O functionality (fwrite becomes sion_write, fseek becomes sion_seek, etc.) which have similar semantics as their C counterparts.

         Gammy is a GUI tool for adjusting pixel brightness/temperature automatically or manually.
         It can dim the screen if its content is too bright, or brighten it otherwise. This can help your eyes adjust when switching between dark and light windows, especially at night or in suboptimal lighting conditions.
         Screenshots available on its website.
