As cofounder of La Quadrature du Net (a NGO fighting for freedoms in the digital age, still waiting for your support ;) ), founder of Octopuce (my company) and more generally as an hacktivist, I often use Tails, a Linux distribution trying to enhance the anonymity of our communications and enhancing our personal digital safety.
Tails is very useful, not only because it allows me to carry important elements of my digital life in a simple USB dongle, protected by a strong password, but it also allows me to use the anonymisation network Tor in excellent conditions.
Sadly, I was missing an important feature, for me but also for all the hacktivists and journalists whose awareness I try to raise on digital freedom and personal data protection. It’s currently not possible to lock a running Tails and require a password to unlock it.
After an hour of research, I finally found a simple solution, allowing you to lock your running Tails with a password, so that you can go away from your computer for a few minutes without putting your personal data in danger.

On January 20th and 22th, one of the servers of la Quadrature du Net, the Paris-based digital freedom association I co-founded and that my company is freely hosting, got hit by some distributed denial of service attacks.
Here is a quick analysis of what we were able to understand about those attacks...

A few month ago, Ladar Levison, founder of Lavabit, an American highly secure email company, was interviewed by the European Parliament to talk about his story against the FBI about his company’s private keys and his user’s confidentiality.
Listen to this video, its really short, and really insightful on the problem of surveillance of private communications, the right to privacy, how he fought against a request from the FBI to massively spy on his users without any control etc.

A few weeks ago, a friend show me a conference of Professor Eben Moglen, lawyer of Philipp Zimmermann (the creator of PGP), founder of the Software Freedom Law Center and Professor at Columbia University, and also a nice and well-known freedom fighter.
I found this conference so insightful, so dense in its content, and so true, that I started to share it with friends. However, many of them are not as fluent in English as they need to be, if they want to get all what Mr Moglen says. So I decided to make a proper English subtitle for it. Here it is!

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 ...

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 ...

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 ?...

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 ! ...
