Library and command line tools for XZ and LZMA compressed files

LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core (>0.15 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (~1 Byte/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio. LZ4 library is provided as open-source software using a BSD license. This benchmark simulates simple "static content transfer" scenario such as OS Kernel compression or video game's static assets (text/images/tables/scripts/etc) which loading from Flash Memory / HDD / SSD. In this case, compression time is completely ignored. Because only content developers compress the data at once and usually they don't care about its computational cost. But they always care end user's experience a.k.a. "loading time" and bandwidth. Please pay attention to "LZ4HC -9" which is quite faster than other methods.

Zstandard is a fast compression algorithm, providing high compression ratios. It also offers a special mode for small data, called dictionary compression. The reference library offers a very wide range of speed / compression trade-off, and is backed by an extremely fast decoder (see benchmarks below). Zstandard library is provided as open source software using a BSD license. Its format is stable and published as IETF RFC 8478. The negative compression levels, specified with --fast=#, offer faster compression and decompression speed in exchange for some loss in compression ratio compared to level 1, as seen in the table above. Zstd can trade compression speed for stronger compression ratios. It is configurable by small increment. Decompression speed is preserved and remain roughly the same at all settings, a property shared by most LZ compression algorithms, such as zlib or lzma.

pngcrush and other tools for manipulating PNG (Portable Network Graphics) and MNG (Multiple-image Network Graphics) files.

uCON64 is a tool to backup all kinds of video games. It supports almost every available backup unit for cartridge-based consoles and performs many other tasks like ROM hacking.

Remote Subversion repository dump

Duff is a Unix command-line utility for quickly finding duplicates in a given set of files. Duff is written in C and should build and run on most modern Unices.

JDIFF is a program that outputs the differences between two binary files, either in binary format or in human readable format (detailed or summarized) and then allows to reconstruct the second file from the first one and the diff-file.

vmdkutil is a utility to manage VMware sparse virtual disk files (.vmdk), creating, cloning, merging, etc.

m23 is a free software distribution system (license: GPL), that installs (via network, starting with partitioning and formatting) and administrates (updates, adds / removes software, adds / removes scripts) clients with Debian, (X/K)Ubuntu and LinuxMint. It is used for deployment of Linux clients in schools, institutions and enterprises. The m23 server is controlled via a web interface. A new m23 client can be installed easily in only three steps. Group functions and mass installation tools make managing a vast number of clients comfortable. The integration of existing clients (with .deb-based distributions) into the system is possible, too. Client backup and server backup are included to avoid data loss. With the integrated virtualisation software, m23 can create and manage virtual m23 clients, that run on real m23 clients or the m23 server. Scripts and software packages (for installation on clients) can be created directly from the m23 web interface.

minidjvu is a DjVu encoder for black-and-white images.

TclTrf is an extension library to the script language tcl, as created by John Ousterhout. It extends the language at the C-and Tcl-with ``transformer''-commands to encode and compress data. Based on the stacked channels of the tcl core (ability inter

This utility converts Motorola S-record files (namely .S19 files) to binary files and vice-versa. It has several useful features that allow full manipulation of record addressing and output file size.

LibSecRm (LIBrary for SECure ReMoval) is a set of replacements for these standard C functions which cause data removing from files. The data is first securely wiped on-the-fly, to protect the user's privacy, then the original functions are called. There is NO NEED to rebuild your software, because LibSecRm is a pre-loadable library, meaning you just need to RUN the software with LibSecRm loaded. LibSecRm is also a development library. The following wiping methods are supported: Gutmann-like, random, Schneier, DoD. See the project homepage https://libsecrm.sourceforge.io and the project Wiki in the menu above. To wipe data that was left on the drive by using "normal" delete operations, you can take a look at WipeFreeSpace (https://wipefreespace.sourceforge.io), which wipes the space used by files marked as deleted (and other things, too).

Clean is a program that searches for backup files and such identified by regular expressions in a ~/.cleanrc, and deletes them: possibly interactively with a per-file y/n decision, or in a batch mode. Clean is written in C and targets Unix/POSIX.

Patches xmms for on the fly recoding id3 tags, m3u playlists, and file names from one encoding to another. Support ID3 tag editing, playlist sorting, encoding autodetection. Configuration available under encodings page of standard xmms preferences.

UPX Tool is a GUI for the popular UPX EXE Compressor. Windows Programs and Dlls, and DOS Programs can be compressed.

Fastjar is an implementation of Sun's jar utility that comes with the JDK, written entirely in C, and runs in a fraction of the time while being 100% feature compatible.

FlashProg is USB base flash memory programmer which is specifically design to read and program 3.3V SPI flash memory devices.

A CVS with simple architecture and easy interface. Use to sincronize automatically a directory, project or for backup. Works in any OS with Perl. FEATURES: web access; client/server; protocol compression; own chksum; Web Admin.

DELOLD is a command line tool used to delete old files with a create date older then a set amount of days. It can do verbose and rescursive with any path given. Perfect for Scheduled and/or batch file jobs.

CoolPackager is a program which will take a .tar.gz file and a installation script file and create a self-extracting executable scipt. Install it on your system by typing this command as root: lynx -source cpkg.sourceforge.net/cpkg | sh

LnxZip is a Gnome front-end to common archive utilities under Linux/Unix. The goal is to provide the end user with a quality tool he/she requires to either work with compressed files or create RPM's. LnxZip is covered under the open source GNU GPL
