LUKS and Yubikey for crypted boot

29 October 2013 in Debian, Hi-Tech, Linux

I recently crypted all my disk as I changed laptop. At the beginning, I just tested a simple password to see performances changes. I didn’t really see changes for the moment. Once I’ve finished to install and configure my needs, I wanted to have a strong password solution. I decided to use a remembered password concatenated to a generated yubikey password. I updated my LUKS tutorial to explain how to update the password.

Debian on the 11,1 model MacBook Pro 13

27 October 2013 in Debian, Hi-Tech, Linux, Mac

I tested to install Debian as I love it more than Mac OS X for work on my new MacBook Pro 13 retina. Most of the hardware works out of the box on a Debian Jessie (because of the kernel version > 3.8) but is not really optimal. That’s why I’m going to explain how I did to make it better. First of all, you need an EFI manager. I discovered that Refit is not maintained anymore and let place to rEFInd instead.

TogetherJS : a real-time collaboration tool

19 October 2013 in Hi-Tech, Linux

Once again Mozilla made a future hit ! TogetherJS is a service you add to an existing website to add real-time collaboration features. Using the tool two or more visitors on a website or web application can see each other’s mouse/cursor position, clicks, track each other’s browsing, edit forms together, watch videos together, and chat via audio and WebRTC. Plugins already exist for WordPress and it’s easy to integrate in any website :-).

Which load web testing tool you recommend ?

15 October 2013 in Hi-Tech, Linux, Web

Hi all, This time, I’m asking help to find a good load testing tool. The one I know is Tsung but it’s not able to speak to some social API. I would like to know what kind of solution you are using and your feedback on it. I already played with Jmeter and I do not remind that it’s able to do better. Any help is appreciated :-) Thanks

I3 : testing an Awesome alternative

11 October 2013 in Hi-Tech, Linux

I’m using Awesome WM for a few months and really like it’s modular LUA configuration file. But I encounter some little problems with window resizing that waste my time day to day and forced me to look at an alternative. A colleague who encountered the same issue talked to Awesome creator (Julien Danjou) that I sometimes have the chance to see at eNovance. It looks like a complicated bug to resolve, he’s not the core maintainer anymore and as it will take too much time to resolve it, this bug shouldn’t be fixed one day.

Ceph Day in London : here we go !

9 October 2013 in Ceph, Hi-Tech, Linux

Ceph is a high availability way to store your data. I really love that solution and how it works. It’s a real good alternative to high cost disks storage. With some colleges of eNovance, we’re currently participating to the Ceph Day today in London (http://www.inktank.com/CEPHdays/). I’m very excited to be here, as I wanted to put in production Ceph, 4-5 years ago (when it was released as experimental in Linux Kernel).

Synology : I finally took a NAS

7 October 2013 in Hi-Tech, Linux

I’ve never really been interested in NAS solutions as I’ve always made my own server and installed what I needed manually. In addition I always thought that it was closed sources since a friend show me I was wrong. He definitively convinced me and I bought a Synology DS713+ last week. It’s really easy to use, brings a lot of features and the biggest point : it’s an open system. I mean that you can have root access on a busy box and do what you want.
