Le but de CAcert est par la sensibilisation et l'éducation de promouvoir la sécurité informatique au travers de la cryptographie, spécialement en mettant à disposition des certificats cryptographiques. Ces certificats peuvent être utilisés pour chiffrer des courriels et les signer électroniquement, authentifier et habiliter des utilisateurs se connectant sur des sites web ainsi que sécuriser la transmission de données sur internet. Toute application qui supporte le protocole « Secure Socket Layer » (SSL ou TLS) peut utiliser les certificats signés par CAcert, comme peut le faire toute application qui utilise des certificats X.509, par exemple pour du chiffrement, de la signature de code ou de la signature de documents.

The Reverberation Machine is a synthetic atmosphere creator. Use the effect on any instrument to add depth and simulate different environments. Experiment and combine a variety of settings to obtain the perfect ambiance for your sound.

The controls on this pedal are straightforward. Volume, Altitude, Reverb Blend and two distinct reverb flavors: Bright Sunshine and Dark Star. Altitude adjusts the gain structure of the reverb and the clean simultaneously creating exciting new reverberation soundscapes that span from subtle to wild.

Although the controls are extremely easy to use and intuitive, there is a vast array of sounds. Everything from simulations of vintage amp verb, playing in a cave, large concert halls, and space ships being sucked into wormholes.

Pflogsumm is a log analyzer for Postfix. It can mail out a summery on a daily, weekly or monthly basis and is fully configurable. The generated report can show you patterns in email traffic so you can better determine bandwidth limitations, mail server abusers or if your mail server needs to be upgraded. Statistics can be very helpful in showing, for example, when most of your mail is sent or received or if that one mail user is sending out more than their fair share of mail. Pflogsumm will give you the ability to quickly determine what machines on your network are the top (ab)users and the proof to follow up company policies with numbers.

Pflogsumm is a single perl file and its only dependancies are perl, the perl module Date::Calc (which is probably already installed on your system) and the proper location of a Postfix log file.

The Sonar™ is a “tremolo” pedal, but this one’s different. This unit has the ability to chop up any signal you send into or out of it. Unlike most other tremolos, it can cut down your high gain signal to silence. It can also sound gorgeously transparent like a traditional tremolo. It does other fun stuff like increase or decrease tempo, duty cycle (amount of time the trem is ON in a given cycle), or both simultaneously on the fly. It also has tap tempo and a slew of advanced features (attack, release, and depth controls). Lastly, and perhaps most importantly, it has aZVEX Machine™ circuit built right into the box.

Open source libraries are very popular in Java world. Nowadays Java/J2EE/Android developers often work with Java-based projects which using a lot of open source Java libraries.

One issue with using open source Java libraries is how to find documentation/source code for these open source libraries fast and easily? It is tedious and time consuming to search for the source code, download and attach source code packages to the libraries. If your project has 40 libraries, how long will it take to find source code for all libraries?

The solution is to use this Eclipse plugin to do the task for you with only one mouse click. This Eclipse plugin will help to find source code for open source Java libraries automatically from Internet. Just right click on a Java library, choose the menu item "Attach Java Source" and wait. The source code for the library will be found and attached to the Java library in several seconds.

ncdu (NCurses Disk Usage) is a disk utility for Linux systems. Its name refers to its similar purpose to the du utility, but ncdu uses a TUI under the [n]curses programming library.[1] Users can navigate the list using the arrow keys and delete files that are taking up too much space by pressing the 'd' key. Version 1.09 and later can export the file listing in JSON format.

ncdu was developed by Yoran Heling to learn C and to serve as a disk usage analyzer on remote systems over ssh.

It's an interesting dilemma. There are two obstacles to doing this in sed. One is that sed operates line by line and never sees the newline endings. Second, sed's regular expressions don't provide a way to exactly match a newline character.

If you really want to do this, don't use sed; use tr.
cat file | tr '\n' ','

A Perl REPL !

SpeedCrunch is a high-precision scientific calculator. It features a syntax-highlighted scrollable display and is designed to be fully used via keyboard. Some distinctive features are auto-completion of functions and variables, a formula book, and quick insertion of constants from various fields of knowledge. Available for Windows, OS X, and Linux in a number of languages.

pflogsumm.pl is designed to provide an over-view of postfix activity, with just enough detail to give the administrator a "heads up" for potential trouble spots. The following is an over-view of the reports produced.

find . -iname '*.gz' -print0 | xargs -0 zgrep PATTERN

The infinality patchset aims to greatly improve freetype2 font rendering.

SASL est un daemon qui permet l’authentification smtp avec Postfix.

Postfix is the default Mail Transfer Agent (MTA) for Ubuntu. It is in Ubuntu's main repository, which means that it receives security updates. This guide explains how to install and configure postfix and set it up as an SMTP server using a secure connection.

The problem with lxdm (and slim) was that when started, it showed only a black screen and blocked for about a minute.

Ncdu is a disk usage analyzer with an ncurses interface. It is designed to find space hogs on a remote server where you don't have an entire gaphical setup available, but it is a useful tool even on regular desktop systems. Ncdu aims to be fast, simple and easy to use, and should be able to run in any minimal POSIX-like environment with ncurses installed.

This piece of software will protect you against screens blue light, letting you sleep when your brain asks for it.

sbin - superuser bin

/sbin is a standard subdirectory of the root directory in Linux and other Unix-like operating systems that contains executable (i.e., ready to run) programs. They are mostly administrative tools, that should be made available only to the root (i.e., administrative) user.
