(N)compress provides the original compress and uncompress programs that used to be the de facto UNIX standard for compressing and uncompressing files. These programs implement a fast, simple Lempel-Ziv (LZW) file compression algorithm.

This package provides a parallel implementation of gzip that exploits multiple processors and multiple cores when compressing data.

GNU Gzip provides data compression and decompression utilities; the typical extension is ".gz". Unlike the "zip" format, it compresses a single file; as a result, it is often used in conjunction with "tar", resulting in ".tar.gz" or ".tgz", etc.

Parallel Zstandard (PZstandard or pzstd) is a multi-threaded implementation of the Zstandard compression algorithm. It is fully compatible with the original Zstandard file format and command-line interface, and can be used as a drop-in replacement.

Compression is distributed over multiple processor cores to improve performance, as is the decompression of data compressed in this manner. Data compressed by other implementations will only be decompressed by two threads: one performing the actual decompression, the other input and output.

Archive huge numbers of files, or split massive tar archives into smaller chunks.

Ziptime helps make .zip archives reproducible by replacing timestamps in the file header with a fixed time (1 January 2008).

``Extra fields'' are not changed, so you'll need to use the -X option to zip to prevent it from storing the ``universal time'' field.

ISA-L is a collection of optimized low-level functions targeting storage applications. ISA-L includes:

• Erasure codes: fast block Reed-Solomon type erasure codes for any encode/decode matrix;

• CRC: fast implementations of cyclic redundancy check. Six different polynomials supported: iscsi32, ieee32, t10dif, ecma64, iso64, jones64;

• Raid: calculate and operate on XOR and P+Q parity found in common RAID implementations;

• Compression: fast deflate-compatible data compression;

• De-compression: fast inflate-compatible data compression;

• igzip: command line application like gzip, accelerated with ISA-L.

This library allows reading and writing gzip-compressed JSON catalog files, which can be used to store GPG, PKCS-7 and SHA-256 checksums for each file.

Compton is a compositor for the Xorg display server and a for of xcompmgr-dana, which implements some changes like:

• OpenGL backend (--backend glx), in addition to the old X Render backend.

• Inactive window transparency (-i) and dimming (--inactive-dim).

• Menu transparency (-m, thanks to Dana).

• Shadows are now enabled for argb windows, e.g terminals with transparency

• Removed serverside shadows (and simple compositing) to clean the code, the only option that remains is clientside shadows.

• Configuration files (see the man page for more details).

• Colored shadows (--shadow-[red/green/blue]).

• A new fade system.

• VSync support (not always working).

• Blur of background of transparent windows, window color inversion (bad in performance).

• Some more options...

Picom is a standalone compositor for Xorg, suitable for use with window managers that do not provide compositing.

Picom is a fork of compton, which is a fork of xcompmgr-dana, which in turn is a fork of xcompmgr.

The gem5 simulator is a modular platform for computer-system architecture research, encompassing system-level architecture as well as processor microarchitecture.

Ripes is a visual computer architecture simulator and assembly code editor built for the RISCV instruction set architecture.

This package helps to manage personal configuration files across multiple machines.

BundleWrap is a decentralized configuration management system that is designed to be powerful, easy to extend and extremely versatile.

By allowing for easy and low-overhead config management, BundleWrap fills the gap between complex deployments using Chef or Puppet and old school system administration over SSH. While most other config management systems rely on a client-server architecture, BundleWrap works off a repository cloned to local machine. It then automates the process of SSHing into servers and making sure everything is configured the way it's supposed to be.

Konsave is CLI that lets you backup your dotfiles and switch to other ones. Features:

• storing configurations in profiles

• exporting profiles to '.knsv' files

• import profiles from '.knsv' files

• official support for KDE Plasma

The rcm suite of tools is for managing dotfiles directories. This is a directory containing all the .*rc files in your home directory (.zshrc, .vimrc, and so on). These files have gone by many names in history, such as “rc files” because they typically end in rc or “dotfiles” because they begin with a period. This suite is useful for committing your rc files to a central repository to share, but it also scales to a more complex situation such as multiple source directories shared between computers with some host-specific or task-specific files.

An EFL user interface for the connman connection manager.

Cmst is a Qt based frontend for the connman connection manager. This package also provides a systemtray icon.

Connman provides a daemon for managing Internet connections. The Connection Manager is designed to be slim and to use as few resources as possible. It is fully modular system that can be extended through plug-ins. The plug-in approach allows for easy adaption and modification for various use cases. Connman implements DNS resolving and caching, DHCP clients for both IPv4 and IPv6, link-local IPv4 address handling and tethering (IP connection sharing) to clients via USB, ethernet, WiFi, cellular and Bluetooth.

RootlessKit is a Linux-native implementation of "fake root" using (code user_namespaces(7)). It is used to run containers engines as an unprivileged user, known as "Rootless mode".

A toolkit to run, read and write docker-compose.yml files with Guix machinery.

Conmon is a monitoring program and communication tool between a container manager (like Podman or CRI-O) and an Open Container Initiative (OCI) runtime (like runc or crun) for a single container.

Buildah is a command-line tool to build OCI container images. More generally, it can be used to:

• create a working container, either from scratch or using an image as a starting point;

• create an image, either from a working container or via the instructions in a Dockerfile;

• mount a working container's root filesystem for manipulation;

• use the updated contents of a container's root filesystem as a filesystem layer to create a new image.

crun is a fast and low-memory footprint Open Container Initiative (OCI) Container Runtime fully written in C.
