I am a developer of the modern web. And for more than a decade I am a rigorous practitioner of Open Source.
My day job at SUSE.com is hacking, operating and maintaining the Linux distribution development platform Open Build Service.

Involved Projects and Packages
zdaemon is a Python package which provides APIs for managing
applications run as daemons. Its principal use to date has been to
manage the application server and storage server daemons for Zope / ZEO,
although it is not limited to running Python-based applications
An event publishing system and a very simple event-dispatching system on
which more sophisticated event dispatching systems can be built. For
example, a type-based event dispatching system that builds on zope.event
can be found in zope.component.
Proxies are special objects which serve as mostly-transparent wrappers
around another object, intervening in the apparent behavior of the
wrapped object only when necessary to apply the policy (e.g., access
checking, location brokering, etc.) for which the proxy is responsible.
This Perl script makes it easy to create MP3 files from an audio CD. It
tries to find the artist and song titles with the help of CDDB.
rlwrap uses the GNU readline library to allow the editing of keyboard
input for any other command. The input history is remembered across
invocations, separately for each command;history completion and search
work as in bash and completion word lists can be specified on the
Tails a given file anywhere on your X Window System root window with a
transparent background. It is customizable with regards to font, color,
rpmrebuild allows to build an rpm file from an installed rpm, or from
another rpm file, with or without changes (batch or interactive). It
can be extended by a plugin system. A typical use is to easy repackage
a software after some configuration's change.
rsnapshot is a filesystem snapshot utility for making backups of local
and remote systems. Using rsync and hard links, it is possible to keep
multiple, full backups instantly available. The disk space required is
just a little more than the space of one full backup, plus
incrementals. Depending on your configuration, it is quite possible to
set up in just a few minutes. Files can be restored by the users who
own them, without the root user getting involved. There are no tapes to
change, so once it's set up, you may never need to think about it
tvtime is a high quality television application for use with video
capture cards. tvtime processes the input from a capture card and
displays it on a computer monitor or projector. Unlike other
television applications, tvtime focuses on high visual quality.
tvtime supports: * Deinterlaced output at a full interlaced rate of
59.94 frames per second for NTSC source or 50 frames per second
for PAL sources. This gives smoothness of motion and high visual
* Multiple deinterlacing algorithms for finding the optimal mode for
your video content and available processor speed.
* 16:9 aspect ratio mode for the highest available resolution when
processing input from an external DVD player or digital satellite
* A super-slick on-screen display for the complete television
experience, with a feature-rich menu system.
* 2-3 Pulldown detection for optimal quality viewing of film content
from NTSC sources.
You can find more information at http://tvtime.net/.
Wmctrl provides command line access to almost all the features defined
in the EWMH specification. Using it, it's possible to, for example,
obtain information about the window manager, get a detailed list of
desktops and managed windows, switch and resize desktops, change number
of desktops, make windows full-screen, always-above or sticky, and
activate, close, move, resize, maximize and minimize them.
The command line access makes it easy to automate these tasks and
execute them from any application that is able to run a command in
response to some event.
Please note that wmctrl only works with window managers which implement
This program is used for getting and setting X11 Xv attributes such as
XV_BRIGHTNESS, XV_CONTRAST, XV_SATURATION, XV_HUE, XV_COLORKEY, etc.
You must have a version of X11 with the XVideo extension and a graphic
card that has Xv graphics acceleration. to work with this program .
Unlike most monitoring tools that either focus on a small set of
statistics, format their output in only one way, run either
interatively or as a daemon but not both, collectl tries to do it all.
The Courier authentication library provides authentication services for
other Courier applications.
Courier-IMAP is a fast, scalable, enterprise IMAP server that uses
Maildirs. Many E-mail service providers use Courier-IMAP to easy handle
hundreds of thousands of mail accounts. With its built-in IMAP and POP3
aggregation proxy, Courier-IMAP has practically infinite horizontal
scalability. In a proxy configuration, a pool of Courier servers service
initial IMAP and POP3 connections from clients. They wait to receive the
client's log in request, look up the server that actually holds this mail
account's mailbox, and establish a proxy connection to the server, all in
a single, seamless process. Mail accounts can be moved between different
servers, to achieve optimum resource usage.
The only practical limitation on Courier-IMAP is available network and I/O
bandwidth. If you are new to Courier-IMAP, this may sound a bit
intimidating. But you do not need to tackle everything at once. Start by
taking small, easy steps. Your first step will be to set up a small
Courier-IMAP server, using it like any other traditional IMAP service, on
a single server. After you gain experience and become comfortable with
Courier, you can then begin exploring its advanced features.
This is the same IMAP server that's included in the Courier mail server,
but configured as a standalone IMAP server that can be used with other
mail servers - such as Qmail, Exim, or Postfix - that deliver to maildirs.
If you already have Courier installed, you do not need to download this
version. If you install this version, you must remove it if you later
install the entire Courier server.
Ding is a smart X Window System English-to-German dictionary. It works
with a local database file. For full functionality, agrep should be
ez-ipupdate is a small utility for updating your hostname for any of
the dynamic DNS services offered at:
* http://gnudip.cheapnet.net (GNUDip)
* http://www.dyn.ca (GNUDip)
fs-check checks file system sizes to see if they are getting too full.
It uses a configuration file that specifies the file systems to check,
e-mail contacts, trigger thresholds (percentage or amount used and
unused), and a report program to run. It includes fs-report, which
shows things like the largest files, the newest files, and core files.
It can be run from cron or as a daemon.
Gcal is a program for printing calendars. Gcal displays a calendar for
a month or a year, eternal holiday lists, and fixed date lists. The
program correctly omits the dates that were skipped when the current
Gregorian calendar replaced the earlier Julian calendar.
help2man is a script to create simple man pages from the --help and
--version output of programs.
Since most GNU documentation is now in info format, this provides a way
to generate a placeholder man page pointing to that resource while
still providing some useful information.
IMAPFilter is a mail filtering utility. It connects to remote mail
servers using the Internet Message Access Protocol (IMAP), sends
searching queries to the server and processes mailboxes based on the
results. It can be used to delete, copy, move, flag, etc. messages
residing in mailboxes at the same or different mail servers. The 4rev1
and 4 versions of the IMAP protocol are supported.
IMAPFilter uses the Lua programming language as a configuration and
The server part (package knockd) listens to all traffic on an ethernet
(or PPP) interface, looking for special "knock" sequences of port hits.
This client makes these port hits by sending a TCP (or UDP) packet to a
port on the server. This port does not need to be open. Since knockd
listens at the link-layer level, it sees all traffic even if it is
destined for a closed port. When the server detects a specific sequence
of port hits, it runs a command defined in its configuration file. This
can be used to open up holes in a firewall for quick access.
This is an attempt at implementing a mailing list manager with the same
functionality as EZMLM, but with the MIT/X11 license and no mail server
Pdsh is a multithreaded remote shell client which executes commands on
multiple remote hosts in parallel. Pdsh can use several different
remote shell services, including standard "rsh", Kerberos IV, and ssh.
