Rant about Github pull-request workflow implementation
One of my recent innocent tweet about Gerrit vs Github triggered much more reponses and debate that I expected it to. I realize that it might be worth explaining a bit what I meant, in a text longer than 140 characters.
OpenStack Design Summit Havana, from a Ceilometer point of view

Hy, Lisp in Python
I’ve meant to look at Hy since Paul Tagliamonte started to talk to me about it, but never took a chance until now. Yesterday, Paul indicated it was a good time for me to start looking at it, so I spent a few hours playing.
Announcing Climate, the OpenStack capacity leasing project
While working on the XLcloud project (HPC on cloud) it appeared clear to us that OpenStack was missing a critical component towards resource reservations.

For the first time, I’ll be at FOSDEM 2013 in Brussels on Sunday 2nd February 2013.
Overriding cl-json object encoding
CL-JSON provides an encoder for Lisp data structures and objects to JSON format. Unfortunately, in some case, its default encoding mechanism for CLOS objects isn’t exactly doing the right thing. I’ll show you how Common Lisp makes it easy to change that.

Integrating cl-irc and cl-async
Recently, I’ve started programming in Common Lisp.
My idea here is to use cl-irc, an IRC library into an event loop. This can be really useful, for example to trigger action based on time, using timers.

Logitech Unifying devices support in UPower
A few months ago, I wrote about my reverse engineering attempt to Logitech Unifying devices. Back then, I concluded my post with big hopes on the future after receiving a document with some part of the specification of the HID++ 2.0 from Logitech.
A couple of weeks ago, some of my summer work has been merged to UPower, adding battery support for some Logitech devices.

Inside Synaps, a CloudWatch-like implementation for OpenStack
A few days ago, Samsung released the source code of Synaps, an implementation of the Amazon Web Service CloudWatch API for OpenStack.
Being a developer on the Ceilometer project, I’ve been curious to look on this project and how it could overlap with Ceilometer or other projects like Heat.

Ceilometer 0.1 released
After 6 months of development, we are proud to release the first release of Ceilometer, the OpenStack Metering project. Ceilometer. This is a first and amazing milestone for us: we follow all other projects by releasing a version for Folsom!
Using Ceilometer, you should now be able to meter your OpenStack cloud and retrieve its usage to build statistics or bill your customer!

Gnus notifications
Today, I’ve merged my Gnus notifications module inside Gnus git repository. This way, it will be available for everybody in Emacs 24.2.
Sony Vaio Z Debian Linux support
I had to install Debian Wheezy on a brand new Sony Vaio Z laptop with the new Ivy Bridge architecture (SVZ1311C5E). I’ll talk about this here, because it’s always nice to know that new hardware works quite fine (or not) under Debian.
Ceilometer, the OpenStack metering project

Logitech K750 keyboard and Unifying Receiver Linux support
A year ago, I bought a Logitech Wireless Solar Keyboard K750. I’m particularly picky on keyboards, but this one is good. It has an incredible useful feature: while being wireless, it has no need for disposable or rechargeable batteries, it uses solar power!
My problem is that there’s obviously no way to know the battery status from Linux, the provided application only working on Windows.
Making the jump: working freelance
For the last 10 years, I’ve been working on many Free Software projects. From Debian to OpenStack, through awesome, Emacs, XCB and many more. This obviously allowed me to enhance my technical skills, but it also taught me about Free Software and Open Source development processes, and how to work with and close to the community.
Working for almost 6 years at Easter-eggs taught me how to work in an autonomous manner, how to lead and manage a project. And how to run a company, thanks to the cooperative status of this great one.
These are the reasons why I decided to leave my latest job and run my own company to work as a freelance consultant & developer specialized in Free Software, starting today.

OpenStack Swift eventual consistency analysis & bottlenecks
Swift is the software behind the OpenStack Object Storage service.
This service provides a simple storage service for applications using RESTful interfaces, providing maximum data availability and storage capacity.
I explain here how some parts of the storage and replication in Swift works, and show some of its current limitations.
If you don’t know Swift and want to read a more “shallow” overview first, you can read John Dickinson’s Swift Tech Overview.

Org-mode and holidays
Org-mode has a nice option which allows you to show week-end days in a different color in your agenda. That means that Saturday and Sunday (when I do not work) are fontified with org-agenda-date-weekend.
Google Maps for Emacs: moving, caching and home
Last week, I worked on my Google Maps for Emacs extension. I’ve introduced a new format handling for locations which include the longitude and latitude. The initial format was just a string describing the location, which was obviously too limited.

ATL1E support in 2.6.26-1

So, as suggested by Maximilian Attems, I provided a clean patch for this driver, made from a cherry-pick from the linux-netdev 2.6.27 tree. It has been committed into the 2.6.26-1 Debian kernel, which will be furnished with Lenny.
