Sonar est une plate-forme libre (LGPL v3) permettant de gérer la qualité du code source Java (exécution de tests unitaires, analyse de la couverture du code par ces tests, vérification du respect des règles de codage, complexité du code, etc.).
FindBugs is a program to find bugs in Java programs. It looks for instances of "bug patterns" code instances that are likely to be errors.
rabroué le multitâche
Qui l'eut cru ? Utiliser plusieurs applications simultanément ne nous rend pas plus productifs. Bien au contraire. Selon les scientifiques, le multitâche a plutôt un effet nocif sur notre cerveau car le changement de contexte permanent dégrade la mémoire et les capacités d'apprentissage. Sur le court terme, il nuit à la concentration et élève notre niveau de stress. Mais à plus long terme, il peut conduire à l'atrophie du cerveau. On n'était peut-être pas si mal lotis sous DOS…

«Le kms est le fait que c'est le noyau qui apporte la gestion des accès à la carte graphique. Cela permet par exemple de faire tourner le serveur graphique sans lui donner de permissions de type root. Cela permettra également d'avoir des messages d'erreurs graphiques (l'écran marron de la mort ?). Et cela permettra d'éviter d'avoir des écrans qui scintillent/clignotent lors de changements de résolutions ou de basculements entre terminaux.»

NAME
iptraf - Interactive Colorful IP LAN Monitor
SYNOPSIS
iptraf { [ -f ] [ -q ] [ -u ] [ { -i iface | -g | -d iface | -s iface |
-z iface | -l iface } [ -t timeout ] [ -B [ -L logfile ] ] ] | [ -h ] }
DESCRIPTION
iptraf is an ncurses-based IP LAN monitor that generates various net‐
work statistics including TCP info, UDP counts, ICMP and OSPF informa‐
tion, Ethernet load info, node stats, IP checksum errors, and others.
If the command is issued without any command-line options, the program
comes up in interactive mode, with the various facilities accessed
through the main menu.

NAME
iftop - display bandwidth usage on an interface by host
SYNOPSIS
iftop -h | [-nNpbBP] [-i interface] [-f filter code] [-F net/mask]
DESCRIPTION
iftop listens to network traffic on a named interface, or on the first
interface it can find which looks like an external interface if none is
specified, and displays a table of current bandwidth usage by pairs of
hosts. iftop must be run with sufficient permissions to monitor all
network traffic on the interface; see pcap(3) for more information, but
on most systems this means that it must be run as root.
By default, iftop will look up the hostnames associated with addresses
it finds in packets. This can cause substantial traffic of itself, and
may result in a confusing display. You may wish to suppress display of
DNS traffic by using filter code such as not port domain, or switch it
off entirely, by using the -n option or by pressing R when the program
is running.
By default, iftop counts all IP packets that pass through the filter,
and the direction of the packet is determined according to the direc‐
tion the packet is moving across the interface. Using the -F option it
is possible to get iftop to show packets entering and leaving a given
network. For example, iftop -F 10.0.0.0/255.0.0.0 will analyse packets
flowing in and out of the 10.* network.
The platform is freely (AGPL) available at :
There are plenty of plugins and application that can use it, and for
example it is working with :
* webinterface
* Jabber/GTalk
* email
* SMS
For those who only want to try it, they even made a concurrent of
twitter using the platform :

powertop is a program that shows the power consumption on Intel-based
laptops and makes suggestions on how to extend battery lifetime.

NAME
rubber - a building system for LaTeX documents
SYNOPSIS
rubber [options] sources ...
rubber-pipe [options]
DESCRIPTION
Rubber is a wrapper for LaTeX and companion programs. Its purpose is,
given a LaTeX source to process, to compile it enough times to resolve
all references, possibly running satellite programs such as BibTeX,
makeindex, Metapost, etc. to produce appropriate data files.
The command rubber builds the specified documents completely. The
source files may be either LaTeX sources (in which case the suffix .tex
may be omitted) or documents in a format Rubber knows how to translate
into LaTeX (this currently means CWEB or Literate Haskell documents).
If one compilation fails, the whole process stops, including the compi‐
lation of the next documents on the command line, and rubber returns a
non-zero exit code.

HotCRP is conference management software: it accepts paper submissions and manages the review process. Many conference management packages are available nowadays, including START/Softconf, Linklings, EasyChair, and Dirk Grunwald's original CRP. (I haven't used Conferencereview.com or Continue.) HotCRP is better than the original CRP. Relative to the others, as of early 2007 it is easier for PC members to navigate from paper to paper and to search for papers in HotCRP, but START's single-page paper submission form is easier than HotCRP's paper submission process (HotCRP includes an email validation step). If you don't like HotCRP try START. Linklings is not in the same class.
HotCRP is open source and requires that you run your own server, although the initial setup process is quite easy and should take about 15 minutes on a modern Linux or BSD box. Software requirements: Apache, PHP version 5 or higher, and MySQL version 5 or higher, plus several PHP packages. The README for the latest release has more.
HotCRP was written for the HotNets V workshop in 2006, and used thereafter for USENIX 2007, SIGCOMM 2007, and SOSP 2007, among many others. It is based on Dirk Grunwald's CRP but is mostly rewritten by now.

protects machines from accidental shutdowns/reboots
The package installs a shell script that overrides the existing shutdown/reboot/halt/poweroff commands and first runs a set of scripts, which all have to exit successfully, before molly-guard invokes the real command.
One of the scripts checks for existing SSH sessions. If any of the four commands are called interactively over an SSH session, the shell script prompts you to enter the name of the host you wish to shut down. This should adequately prevent you from accidental shutdowns and reboots.
This shell script passes through the commands to the respective binaries in /sbin and should thus not get in the way if called non-interactively, or locally.
