This simple daemon feeds entropy from the CPU Jitter RNG core to the kernel Linux's entropy estimator. This prevents the /dev/random device from blocking and should benefit users of the preferred /dev/urandom and getrandom() interfaces too.

The CPU Jitter RNG itself is part of the kernel and claims to provide good entropy by collecting and magnifying differences in CPU execution time as measured by the high-resolution timer built into modern CPUs. It requires no additional hardware or external entropy source.

The random bit stream generated by jitterentropy-rngd is not processed by a cryptographically secure whitening function. Nonetheless, its authors believe it to be a suitable source of cryptographically secure key material or other cryptographically sensitive data.

If you agree with them, start this daemon as early as possible to provide properly seeded random numbers to services like SSH or those using TLS during early boot when entropy may be low, especially in virtualised environments.

The rasdaemon daemon monitors platform RAS reports from Linux kernel trace events. These trace events are logged in /sys/kernel/debug/tracing and reported through standard log mechanisms like syslog.

Zerofree finds the unallocated blocks with non-zero value content in an ext2, ext3, or ext4 file system and fills them with zeroes (or another value). This is a simple way to make disk images more compressible. Zerofree requires the file system to be unmounted or mounted read-only.

Touchégg is an application that runs in the background and transform the gestures you make on your touchpad or touchscreen into visible actions in your desktop.

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs.

Btrfs is a CoW file system for Linux aimed at implementing advanced features while focusing on fault tolerance, repair and easy administration.

The Python scripts in this project generate a GTK-UI to change TLP configuration files easily. It aims to protect users from setting bad configuration and to deliver a basic overview of all the valid configuration values.

Libavc1394 is a programming interface to the AV/C specification from the 1394 Trade Association. AV/C stands for Audio/Video Control.

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs.

The reform2_lpc module allows for interaction with the NXP LPC11U24 Cortex-M0 MCU system controller in the Reform 2 open hardware laptop. It provides battery status information and is necessary to completely shut down the system when powering it off via userspace.

Aumix adjusts an audio mixer from X, the console, a terminal, the command line or a script.

PRoot is a user-space implementation of chroot, mount --bind, and binfmt_misc. This means that users don't need any privileges or setup to do things like using an arbitrary directory as the new root file system, making files accessible somewhere else in the file system hierarchy, or executing programs built for another CPU architecture transparently through QEMU user-mode. Also, developers can use PRoot as a generic process instrumentation engine thanks to its extension mechanism. Technically PRoot relies on ptrace, an unprivileged system-call available in the kernel Linux.

The sysstat utilities are a collection of performance monitoring tools for Linux. These include mpstat, iostat, tapestat, cifsiostat, pidstat, sar, sadc, sadf and sa.

Collection of tools to query what type of USB devices are connected to the system, including lsusb. The experimental usbreset command included in the package, but be aware that it may not work for all devices.

NUMA stands for Non-Uniform Memory Access, in other words a system whose memory is not all in one place. The numactl program allows you to run your application program on specific CPUs and memory nodes. It does this by supplying a NUMA memory policy to the operating system before running your program.

The package contains other commands, such as numastat, memhog, and numademo which provides a quick overview of NUMA performance on your system.

F2FS, the Flash-Friendly File System, is a modern file system designed to be fast and durable on flash devices such as solid-state disks and SD cards. This package provides the userland utilities.

perf is a tool suite for profiling using hardware performance counters, with support in the Linux kernel. perf can instrument CPU performance counters, tracepoints, kprobes, and uprobes (dynamic tracing). It is capable of lightweight profiling. This package contains the user-land tools and in particular the perf command.

This simple Linux kernel module allows calls from user space to any ACPI method provided by your computer's firmware, by writing to /proc/acpi/call. You can pass any number of parameters of types ACPI_INTEGER, ACPI_STRING, and ACPI_BUFFER.

It grants direct and undocumented access to your hardware that may cause damage and should be used with caution, especially on untested models.

iptables is the user-space command line program used to configure the Linux 2.4.x and later IPv4 packet filtering ruleset (firewall), including NAT (Network Address Translation).

This package also includes ip6tables, which is used to configure the IPv6 packet filter.

Both commands are targeted at system administrators.
