For the last 3 years, I've been working in the OpenStack Telemetry team at eNovance, and then at Red Hat.

After a few weeks of hard work with the team, here is the new major version of Gnocchi, stamped 3.0.0.

Writing a book is a big undertaking.

When working with timestamps, one question that often arises is the precision of those timestamps.

A few weeks ago, I recorded an interview with Krishnan Raghuram about what was discussed for this development cycle for OpenStack Telemetry at the Austin summit.

Three years after my definitive guide on Python classic, static, class and abstract methods, it seems to be time for a new one.

During the OpenStack summit a few weeks ago, I had the chance to talk to some people about my experience on running open source projects.

Last week was the sixth edition of the Paris Monitoring Meetup, where I was invited as a speaker to present and talk about Gnocchi.

Exactly a year ago, I released the second edition of my book The Hacker's Guide to Python.

It's again that time of the year, where we all fly out to a different country to chat about OpenStack and what we'll do during the next 6 months.

A little less than 2 months after our latest major release, here is the new minor version of Gnocchi, stamped 2.1.0.

There's a lot of situation where you end up needing a software deployed temporarily.

When I started contributing to OpenStack, almost five years ago, it was a small ecosystem.

A little more than 3 months after our latest minor release, here is the new major version of Gnocchi, stamped 2.0.0.

The first major version of the scalable timeserie database I work on, Gnocchi was a released a few months ago.

Last week-end, I was in Brussels, Belgium for the FOSDEM, one of the greatest open source developer conference.

Writing programs is fun, but making them fast can be a pain.

Finally, Gnocchi 1.3.0 is out.

Last week I was in Tokyo, Japan for the OpenStack Summit, discussing the new Mitaka version that will be released in 6 months.

We got pretty good feedback on Gnocchi so far, even if we only had little.

Last week, I've been invited to the OpenStack Paris meetup #16, whose subject was about metrics in OpenStack.

A few days ago, the French equivalent of Hacker News, called "Le Journal du Hacker", interviewed me about my work on OpenStack, my job at Red Hat and my self-published book The Hacker's Guide to Python.

We've been hard working with the Gnocchi team these last months to store your metrics, and I guess it's time to show off a bit.

Continuing my post series on the tools I use these days in Python, this time I would like to talk about a library I really like, named voluptuous.

I've started to use Pocket a few months ago to store my backlog of things to read.

It's been a while since I talked about Ceilometer and its companions, so I thought I'd go ahead and write a bit about what's going on this side of OpenStack.

Recently, I've been fighting with the never ending issue of timezones.

The library presented in this article is becoming obsolete and un-maintained.

Last week I was in Vancouver, BC for the OpenStack Summit, discussing the new Liberty version that will be released in 6 months.

I've recently been contacted by Johannes Hubertz, who is writing a new book about Python in German called "Softwaretests mit Python" which will be published by Open Source Press, Munich this summer.

A year passed since the first release of The Hacker's Guide to Python in March 2014.

A few months ago, I wrote a long post about what I called back then the "Gnocchi experiment".

A few months ago, I wrote the definitive guide about Python method declaration, which had quite a good success.

With OpenStack embracing the Tooz library more and more over the past year, I think it's a good start to write a bit about it.

A lot of people read up on good Python practice, and there's plenty of information about that on the Internet.

I've switched my Git repositories to GitHub recently, and started to watch my contributions statistics, which were very low considering I spend my days hacking on open source software, especially OpenStack.

A little more than 2 years ago, the Ceilometer project was launched inside the OpenStack ecosystem.

Last week was the OpenStack Design Summit in Atlanta, GA where we, developers, discussed and designed the new OpenStack release (Juno) coming up.

As promised, today I would like to write a bit about the making of The Hacker's Guide to Python.

When I started writing the landing page for The Hacker's Guide to Python, I wanted to try new things at the same time.

And done!

Yesterday, the second milestone of the Icehouse development branch of Ceilometer has been released and is now available for testing and download.

The Ceilometer project supports various database backend that can be used as storage.

Last week was the OpenStack Design Summit Icehouse in Hong-Kong where we, OpenStack developers, discussed and designed the new OpenStack release (Icehouse) that is coming up.

I love to say that Python is a nice subset of Lisp, and I discover that it's getting even more true as time passes.

Last week, the third and last milestone of the Havana development branch of Ceilometer has been released and is now available for testing and download.

I've been hacking on Python for a lot of years now, on various project.

Doing code reviews is a great way to discover things that people might struggle to comprehend.

Last week, the second milestone of the Havana development branch of Ceilometer has been released and is now available for testing and download.

A month ago, a mail hit the OpenStack mailing list entitled "The OpenStack Community Welcomes Developers in All Programming Languages".
