Update 1 : Debian on the 11,1 model MacBook Pro 13

10 November 2013 in Linux, Mac

So this is my first update to get a full working MacBook Pro under Debian. For now, as already talked in a last post, I’m trying to make every things working. The remaining nonworking things/problems were and the resolutions I’ve found : The iSight Camera : still not working (didn’t had time to search solution neither) The Speaker : should work with the latest kernel and patch (RedHat bugzilla) but didn’t have the time to test it yet (3.

Lego Calendar : An interesting way to manage your team tasks

8 November 2013 in Hi-Tech

The lego calendar is a wall mounted time planner that we invented for our studio. It’s made entirely of lego, but if you take a photo of it with a smartphone all of the events and timings will be magically synchronised to an online, digital calendar. It makes the most of the tangibility of physical objects, and the ubiquity of digital platforms, and it’s also puts a smile on our faces when we use it!

Redshift : screen color temperature adjuster

6 November 2013 in Debian, Hi-Tech, Linux

Redshift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night. Two of my colleagues (Julien and Axel) praise virtues of this application. So I started to use it yesterday. For the moment, my opinion is good during the night, but during the day…I don’t have opinion for the moment. Here is my configuration.

Yubikey : debug your authentication problems

4 November 2013 in Debian, Hi-Tech, Linux

Since I’ve reinstalled my desktop on my new MacBook Pro 13, I had to fight with some problems with my Yubikey. I never had such and wonder if it couldn’t comes from a Debian package update. Anyway, I had problem with permissions on the USB device and found a udev solution. I’ve updated my documentation and let you check and would like a feedback if some of you have encountered the same issue (USB error: Access denied (insufficient permissions))

Galera : Enlarge your gcache

2 November 2013 in Hi-Tech, SQL

Galera uses a preallocated file with a specific size called gcache, used to store the writesets in circular buffer style. By default, its size is 128MB and it’s a good idea to upgrade it to a higher value. I’ve updated my documentation on that if you want to check. In addition, you can find more informations, I suggest a Severalnines link.

OMG, Nagios OpenSource project is almost dead !

31 October 2013 in Hi-Tech, Nagios

This is not a really good news. An announcement at OSMC (Open Source Monitoring Conference) as been made by Andreas Ericsson ( Nagios 4 core dev) about the future of Nagios. Nagios 4 is the latest Core version of the project ! Only the enterprise version will remain (strategic choice of Ethan, the creator). A Nagios 4 fork will appear called Naemon and developed by Andreas Ericsson. I remind as well that the Shinken is a real good alternative and is able to work with your current Nagios configuration.

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.
