DNS & AlternC - How does it work?

Now that AlternC 1.0 is released, you know, that free software, control panel for web and mail hosting on Debian GNU/Linux, you may be interested in knowing that the DNS system has been completely rewritten by Alan, aka Fufroma.

Here are some explanations on the way the DNS works with AlternC 1.0 and later.

Luks Bruteforce : test all your passwords

A few years ago, I started using cryptographic capabilities of Linux to encrypt my usb keys, hard drives and laptop. More efficient against the usual bad guys than a root password, this gave me a pretty good privacy for personal and professional data ...

... Until that day when, after about a year without rebooting, one of my server rebooted and asked me for a passphrase ... which I obviously forgot!

I didn’t find anything on the Internet to bruteforce a Luks-encrypted partition, so here is the script I produced to help me do this efficiently ...

Arduino driver for Sure0832 led panel

When I went to Berlin, Germany in January 2010, I was glad to discover the Arduino electronic board, and the Lol Shield from Jimmie P Rodgers.

We even made, with Coucouf, a Tetris, a Pong and a Space Invader based on the same board Arduino+LolShield

In May 2010, after I bought a bunch of 8x32 led panels from Sure, I wrote a driver to write texts on those panels, and here is the result ...

Nice style for forced form fields

These days, thanks to Chantal and Nicolas, I made many usability improvements to AlternC, the web control panel software suite, the free software project I started long ago...

During my development phase, I created a nice style to show "forced text fields" in web forms. Those text input fields used when part of the field content is locked.

How does it work and how does it looks like ?...

Optical Fiber in France: How it work? Free vs Orange

In France, since 2007, big network operators are installing optical fiber in big cities. This new technology allow a very high speed Internet access, and new services

Since the beginning of the fiber deployment, Orange and Free, the 2 biggest French operators, are using two different technologies to provide us with fiber-based Internet access. What are those technologies ? What are each technology pro & cons ?

Let’s explain this, with some drawings too ! ...

All games for Arduino & Lol-Shield : Pong, Shoot them up, Tetris

Finally, since coucouf, aka Aurélien, sent me the source code of its tetris, I decided to produce a last video summing-up all what we coded for Arduino and LolShield from Jimmie P Rodgers during 26C3 in Berlin... Starting with the graphic library of Alex Wenger, we created some programs and other liibraries : an enhanced version of the Charlieplexing library from Alex, a figure drawing library (Figure.cpp) and text drawing one (Text.cpp), with a minimal font. Jimmie just opened a Google (...)

Google, Akamai, At&T : We are only dumb meat

In July 2004, Patrick Le Lay, who where at this time CEO of TF1 (the first privately owned television in France), was sentenced to a mediatic death because he says a plain thing, which was, at this time, taken out of its context, but which made him notoriously famous :

"What we sell to Coca-Cola, it’s available human brain time. " (cf wikipedia)

Today, I have a far better inappropriate expression to tell you about, an expression that has been totally unnoticed, but that really deserves your attention.

Guess what funny name Internet access providers and Internet content providers gave to Internet Users ?

Let me tell you a little story...

26c3. Day 4 : The LOL Shield, last post : SPACE INVADER !

This is the last article on LOL Shield for Arduino before a while (I guess), this fantastic circuit from Jimmie P Rodgers : We where glad to obtain this wednesday morning a library, (under LGPL license, perfect :) ) created by Alex Wenger, from the ArduinoBuch Blog, which is no less than a graphic driver for the LOL Shield !

26c3. Day 2 : A Microntroller-based led panel from Jimmie

During that second day at the 26th Chaos Communication Congres at Berlin, I choose to make it a manual and active day : Jimmi P Rodgers, a friend of Mitch (the inventor of the TVBGone) brought an electronic kit called "LOL Shield for Arduino". It’s a 14x9 led panel, either green or red, driven by an Arduino, a microcontroller board with an Atmel 328, and a USB/Serial converter, which make it very easily programmable.

Let’s go for a small demo, source and video ...
