pdumpfs: a daily backup system similar to Plan9's dumpfs
What's pdumpfs?
pdumpfs is a simple daily backup system similar to Plan9's dumpfs
which preserves every daily snapshot. pdumpfs is written in Ruby.
You can access the past snapshots at any time for retrieving a certain
day's file. Let's backup your home directory with pdumpfs!
pdumpfs constructs the snapshot YYYY/MM/DD in the destination
directory. All source files are copied to the snapshot directory for
the first time. On and after the second time, pdumpfs copies only
updated or newly created files and stores unchanged files as hard
links to the files of the previous day's snapshot for saving a disk
space.
This program is used to send multiple system commands to a group of UNIX-like
remote servers simultaneously using concurrent processes. Supported protocols:
FTP, SFTP, TELNET, SSH and SCP. With telnet and ssh all system command are
supported provided that they are not interactive.
Its main usage is to send repetitive sysadmin tasks to a group of servers but
you can also use it for automatic ftp or scp backup and much more.
Commands are exactly those you type on your terminal. It also allow you to use
'su -' to execute your commands under the TELNET and SSH protocols.
This is the last version that handles both the 8.x and 9.x install
media formats.
Qjail [ q = quick ] is a 4th generation wrapper for the basic chroot jail
system that includes security and performance enhancements. Plus a new level
of "user friendliness" enhancements dealing with deploying just a few jails or
large jail environments consisting of 100's of jails.
Qjail requires no knowledge of the jail command usage. It uses "nullfs" for
read-only system binaries, sharing one copy of them with all the jails.
Uses "mdconfig" to create sparse image jails. Sparse image jails provide a
method to limit the total disk space a jail can consume, while only occupying
the physical disk space of the sum size of the files in the image jail.
Ability to assign ip address with their network device name,
so aliases are auto created on jail start and auto removed on jail stop.
Ability to create "ZONE"s of identical qjail systems, each with their own
group of jails.
Ability to designate a portion of the jail name as a group prefix so the
command being executed will apply to only those jail names matching that prefix.
This qjail version only supports the RELEASE-10.x series of releases.

system that includes security and performance enhancements. Plus a new level
of "user friendliness" enhancements dealing with deploying just a few jails or
large scale jail environments consisting of 100's of jails.
Qjail uses the jail(8) jail.conf method. This provides the ability to enable
the following options on a per-jail basis. exec.fib, securelevel, allow.sysvipc,
devfs_rulesets, allow.raw_sockets, allow.quotas, allow.mount.nullfs,
allow.mount.tmpfs, allow.mount.zfs, vnet.interface, and vnet. The vnet option
gives a jail its own network stack using the experimental vimage kernel module.
The vnet option has only been tested on i386 and amd64 equipment.

This is a Linux/i386 rpm port of procps.
procps is the package that has a bunch of small useful utilities
that give information about processes using the /proc filesystem.
The package includes the programs ps, top, vmstat, w, kill,
free, slabtop, and skill.
QPxTool is the Linux way to get full control over your CD/DVD drives.
It is the Open Source Solution which intends to give you access to
all available Quality Checks (Q-Checks) on written and blank media,
that are available for your drive. This will help you to find the
right media and the optimized writing speed for your hardware, which
will increase the change for a long data lifetime.
These tests are actually supported:
* PIE / PIF Scan
* TA Scan
* Jitter / Beta Scan
* Transfer Rate Scan
* C1-, C2- and CU-Scan
* Blank Media Quality Check
* FE/TE Scan on blank media
* FE/TE Scan on written media
See webpage to get a list of the currently supported hardware.
QuickSynergy is a graphical interface (GUI) for easily configuring
Synergy2, an application that allows the user to share his mouse and
keyboard between two or more computers.
Without the need for any external hardware, Synergy2 uses the TCP-IP
protocol to share the resources, even between machines with diferent
operating systems, such as Mac OS, Linux and Windows.
This qjail version only supports RELEASE-11.0 and newer.

Rename is a quick and powerful tool written in C, featuring extended
regular expression support for searching and substituting pattern
strings in filenames.
Rename can rename, convert to lowercase/uppercase, and change the
ownership of a large number of files.
The Swap Extender Daemon is designed to monitor the amount of swap space
available on the system and create more on-disk swap as needed. Additionally
Swap Extender will remove unwanted swap space when memory is freed.
