The Ultimate Packer for eXecutables (UPX) is an executable file compressor. UPX typically reduces the file size of programs and shared libraries by around 50%--70%, thus reducing disk space, network load times, download times, and other distribution and storage costs.

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.

A data compression/decompression library for embedded/real-time systems.

Among its features are:

• Low memory usage (as low as 50 bytes.) It is useful for some cases with less than 50 bytes, and useful for many general cases with less than 300 bytes.

• Incremental, bounded CPU use. It can be used to chew on input data in arbitrarily tiny bites. This is a useful property in hard real-time environments.

• Can use either static or dynamic memory allocation.

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.

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...

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

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

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.

This package provides an implementation of Compose Spec for podman focused on being rootless and not requiring any daemon to be running.

This package provides a replacement for libslirp and VPNKit, written in pure Go. It is based on the network stack of gVisor and brings a configurable DNS server and dynamic port forwarding.

It can be used with QEMU, Hyperkit, Hyper-V and User-Mode Linux.

The binary is called gvproxy.

Catatonit is a simple container init tool developed as a rewrite of initrs in C due to the need for static compilation of Rust binaries with musl. Inspired by other container inits like tini and dumb-init, catatonit focuses on correct signal handling, utilizing signalfd(2) for improved stability. Its main purpose is to support the key usage by docker-init: /dev/init – <your program>, with minimal additional features planned.

This package provides a tool for exploring a Docker image, layer contents, and discovering ways to shrink the size of Docker/OCI image.

passt implements a thin layer between guest and host, that only implements what's strictly needed to pretend processes are running locally. The TCP adaptation doesn't keep per-connection packet buffers, and reflects observed sending windows and acknowledgements between the two sides. This TCP adaptation is needed as passt runs without the CAP_NET_RAW capability: it can't create raw IP sockets on the pod, and therefore needs to map packets at Layer-2 to Layer-4 sockets offered by the host kernel.

Also provides pasta, which similarly to slirp4netns, provides networking to containers by creating a tap interface available to processes in the namespace, and mapping network traffic outside the namespace using native Layer-4 sockets.

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

Distrobox is a fancy wrapper around Podman or Docker to create and start containers highly integrated with the hosts.

This package provides Container Network Interface (CNI) plugins to configure network interfaces in Linux containers.

Podman (the POD MANager) is a tool for managing containers and images, volumes mounted into those containers, and pods made from groups of containers.

Not all commands are working out of the box due to requiring additional binaries to be present in the $PATH.

To get podman compose working, install either podman-compose or docker-compose packages.

To get podman machine working, install qemu-minimal, and openssh packages.

libslirp is a user-mode networking library used by virtual machines, containers or various tools.

slirp4netns provides user-mode networking ("slirp") for unprivileged network namespaces.

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.

convmv is a file renamer, that converts between different encodings, e.g. from ISO-8859-1 to UTF-8. It is particularly usefuls for files with names, that display incorrectly.
