    We're very happy to be hosting the next mercurial sprint in our brand new offices in central Paris. It is quite an honor to be chosen when the other contender was Google.

    So a bunch of mercurial developers are heading out to our offices this coming Friday to sprint for three days on mercurial. We use mercurial a lot here over at Logilab and we also contribute a tool to visualize and manipulate a mercurial repository : hgview.

    To check out the things that we will be working on with the mercurial crew, check out the program of the sprint on their wiki.

    What is a sprint? "A sprint (sometimes called a Code Jam or hack-a-thon) is a short time period (three to five days) during which software developers work on a particular chunk of functionality. "The whole idea is to have a focused group of people make progress by the end of the week," explains Jeff Whatcott" [source]. For geographically distributed open source communities, it is also a way of physically meeting and working in the same room for a period of time.

    Sprinting is a practice that we encourage at Logilab, with CubicWeb we organize as often as possible open sprints, which is an opportunity for users and developers to come and code with us. We even use the sprint format for some internal stuff.

  • New supported repositories for Debian and Ubuntu

    2010/01/21 by Arthur Lutz

    For the release of hgview 1.2.0 in our Karmic Ubuntu repository, we would like to announce that we are now going to generate packages for the following distributions :

    • Debian Lenny (because it's stable)
    • Debian Sid (because it's the dev branch)
    • Ubuntu Hardy (because it has Long Term Support)
    • Ubuntu Karmic (because it's the current stable)
    • Ubuntu Lucid (because it's the next stable) - no repo yet, but soon...

    The old packages in the previously supported architectures are still accessible (etch, jaunty, intrepid), but new versions will not be generated for these repositories. Packages will be coming in as versions get released, if before that you need a package, give us a shout and we'll see what we can do.

    For instructions on how to use the repositories for Ubuntu or Debian, go to the following page : http://www.logilab.org/card/LogilabDebianRepository


  • You can now register on our sites

    2009/09/03 by Arthur Lutz

    With the new version of CubicWeb deployed on our "public" sites, we would like to welcome a new (much awaited) functionality : you can now register directly on our websites. Getting an account with give you access to a bunch of functionalities :

    • registering to a project's activity with get you automated email reports of what is happening on that project
    • you can directly add tickets on projects instead of talking about it on the mailing lists
    • you can bookmark content
    • tag stuff
    • and much more...

    This is also a way of testing out the CubicWeb framework (in this case the forge cube) which you can take home and host yourself (debian recommended). Just click on the "register" link on the top right, or here.

  • IPMI plugin for Munin python code published

    2009/06/17 by Arthur Lutz

    As you might have noticed we quite like munin. We use it quite a bit to monitor how our servers and services are doing. One of the things we like about munin is obviously that the plugins can be written in python (and perl, bash and ruby).

    On a few recent servers we started playing with IPMI to sensor the temperature, watts, fan's rpms etc. So we went out looking for a munin plugin for that. We found Peter Palfrader's ruby plugins. There was one small glitch though, we came across a simple bug : the "ipmitool -I open sensor" can be real long to execute on certain machines, so configuring the plugin was a bit painful and running it too. Changing the ruby code was a bit tricky since we don't really know ruby... so we did a quick rewrite of the plugin in python... with a few optimizations.

    It's not really complete but works for us, and might be useful to you, so we're publishing the hg repo. You can get the tgz or browse the source.


  • Nous allons à PyConFr 2009

    2009/05/25 by Arthur Lutz

    Le 30 et 31 mai prochain (samedi et dimanche prochain) nous allons être présents à PyConFr édition 2009, nous sommes partenaire de l'évènement et allons y parler de CubicWeb. Pour être plus précis, Nicolas Chauvat y présentera "CubicWeb pour publier DBpedia et OpenLibrary". Il avait déjà évoqué ces sujets sur ce site : Fetching book descriptions and covers et DBpedia 3.2 released.

    Si vous comptez y aller, n'hésitez pas à venir nous dire bonjour.

  • Almost reached 1000 tickets

    2009/05/13 by Arthur Lutz

    Logilab.org has almost reached a thousand tickets on the Logilab's open source projects. To be exact there are 940 tickets right now. What kind of tickets are they ?

    Here is a quick graph of the state of the tickets in our tracker :

    http://chart.apis.google.com/chart?cht=p&chs=400x200&chd=e:Dc..Iw9EXV&chtt=Logilab.org+tickets+by+state&chl=deprecated%20:%2020|open%20:%20373|rejected%20:%2051|resolved%20:%20358|validated%20:%20136

    Graphing is neat. Maybe soon we'll get this kind of feature automatically in the CubicWeb forge, see this ticket.

  • Belier - le ssh par hops

    2009/02/17 by Arthur Lutz

    On vient de découvrir belier qui permet de se connecter facilement à des machines auquelles on doit accéder par des machines ssh intermédiaires. Ca peut s'avérer utile. En plus, c'est en python. En plus, il a fait des paquets debian... et en plus il mentionne pylint. Du coup il mérite mention ici.

  • Debian Lenny release date - almost there ?

    2009/02/09 by Arthur Lutz
    http://www.debian.org/logos/openlogo-nd-50.png

    Being big fans of debian, we are impatiently awaiting the new stable release of the distribution : lenny. Finding it pretty difficult to find information about when they were expecting to release it, I asked a colleague if he knew. He's a debian developer so I though he might have the info. And he did : according to the debian.devel mailing list we should be having the release for the 14th of February 2009. In other words : in 5 days!

    http://thread.gmane.org/gmane.linux.debian.devel.announce/1318

    There's a few geeky emails on the release date if you have time to read the threads.

  • Apycot big version change

    2009/01/26 by Arthur Lutz

    The version convention that we use is pretty straight forward and standard : it's composed of 3 numbers separated by dots. What are the rules to incrementing each on of these numbers ?

    • The last number is a incremented when bugs are corrected
    • The middle number is incremented when stories (functionalities) are implemented to the software
    • The first number is incremented when we have a major change of technology

    Well... if you've been paying attention, apycot just turned 1.0.0, the major change of technology is that it is now integrated to CubicWeb (instead of just generating html files). So for a project in your forge, you describe the apycot configuration for it, and the tests for quality assurance are launched on a regular basis. We're still in the process of stabilizing it (latest right now it 1.0.5), but it already runs on the CubicWeb projects, see the screenshot below :

    http://www.logilab.org/image/7682?vid=download

    You should also know that now apycot has two components : the apycotbot which runs the tests and an cubicweb-apycot which displays the results in cubicweb (download cubicweb-apycot-1.0.5.tar.gz and apycotbot-1.0.5.tar.gz).
