nonblonde
A Key/data Store
...Nonblonde tables are backed by b-trees that organize their nodes as critical bit trees. It allows multiple tables per store, atomic updates, keys of unlimited size. Head and tail key compression and a variable block size reduce the database disk size. Disk blocks are never modified in place, for which the written database is always in an intended state and does not need repair or recovery. -

XSIBackup-DC
VMWare ESXi Virtual Machine Backup, runs in free ESXi
©XSIBackup-DC is a C binary that runs in the ©ESXi shell and behaves as a backup and replica service. It follows the same principles as our previous ©XSIBackup editions, that is: a utility that runs in the hypervisor command line and accepts arguments and values stating which VMs to backup and where to copy them. It accepts local and remote SSH paths, thus you can backup and replicate VMs to local datastores or to remote repositories in any additional ©ESXi or Linux server. Download... -

rsptar_gzip
TAR based DLL
C code and DLL (with sample project) with library libarchive and GNU tar 1.34 to list, update, delete, extract and create latest GNU tar files uncompressed or compressed with gzip, gzip2, gzip2 multi-thread, bzip2, bzip3, bzip3 multi-thread, lzip, lzop, lzop2, lzop2 multi-thread, lz4, lz5 multi-thread, lzma, brotli, brotli2 multi-thread, Zstandard, xz , the old Unix compression utility 'compress' (.Z) , compress2 multi-thread (.Z2), zip, 7zip and many more formats with full Unicode support when creating and extracting files in windows, compiled with mingw, notice that we have developed a replacement for tar when running in windows with support to file attributes, it is extensible without breaking compatibility with older files, this means that if in the future we add new features to the format it still will be able to extract older VAL files, this is the recommended mode to be used, the extension is .val, support to AES 256, RC4, Serpent, MARS, RC6 and TWOFISH encryption -

Lexical Analyzer Generator Quex
Generator of lexical analyzers in C and C++. Unicode Supported.
The goal of this project is to provide a generator for lexical analyzers of maximum computational efficiency and maximum range of applications. This includes the support for Unicode (UTF8, UTF16, ...) and a large variety of other encodings directly and via nested converters such as ICU(tm) and IConv. Sophisticated buffer handling allows to operate on plain file streams, on sockets, or manually fed buffer content. 'Ready-to-build' examples explain related concepts and facilitate practical... -

nuster
A high performance HTTP proxy cache server and RESTful NoSQL cache
nuster is a high-performance HTTP proxy cache server and RESTful NoSQL cache server based on HAProxy. It is 100% compatible with HAProxy and takes full advantage of the ACL functionality of HAProxy to provide a fine-grained caching policy based on the content of request, response or server status. nuster can be used as an HTTP/TCP load balancer just like HAProxy. nuster can also be used as a RESTful NoSQL cache server, using HTTP POST/GET/DELETE to set/get/delete Key/Value objects. It can be... -

The jbig2dec project is no longer hosted here. Please see: https://www.ghostscript.com JBIG2 is a compression format for lossless and lossy encoding of scanned monochrome documents at moderately high resolution. It is very efficient in that domain, claiming 100:1 compression. jbig2dec is a decoder-only implementation of the format.

Encode_LV
LabVIEW VIs for ZLib compression and Base64/binhex encoding
These VIs use C-based DLL access to ZLib (https://zlib.net/) and ASCII encode/decode. The VIs and development files are included in this package. You are most likely to be running this from a Windows machine which means that loading the LabVIEW code will generate an error. This is due to the LabVIEW code pointing to the Linux SO instead of the DLL. To fix it, double-click on the CLFN VIs and browse to DLL. -

...This is only the main source code here. I have released it to the public domain. Do whatever you want with it. It will not compile as-is. There is at least 1 3rd party compression file missing and the sound/music code was a licensed library that is not open source. The opening/high score/game select screens are also not included. The game itself can be found for free on Steam. The graphics of the game are not open source and may not be used in any commercial projects. The music and sound effects are public domain but I would appreciate credit to "Roy Davis" if you use any of the music. ...

CStore FDW
Columnar storage extension for Postgres
cstore_fdw is a columnar store extension for PostgreSQL built by Citus Data using the Foreign Data Wrapper (FDW) interface. It stores data in a compressed, columnar format that significantly reduces disk I/O for analytical queries. Ideal for read-heavy workloads and time-series data, cstore_fdw enhances Postgres’ ability to serve as a lightweight data warehouse. -
