If you get error 404 with your permalinks and RSS feed after an upgrade of your Wordpress installation to version 2.8.3, it’s worth to check the “Permalinks” section (under the “Settings” tab in the admin panel). Try set it up to “Common”, save changes and then put it back to your previous structure (“Month and name” in my case). This should solve most of current 404 errors after upgrade. If not, check the Wordpress support forum.
This morning, it was impossible to post tweets on Twitter so I finally gave in to install a Twitter client. Amongst many software available, Pwytter seemed interesting to try: free software, written in Python were my two criteria. Unfortunately, the installation process is not straightforward (although its use of the general python setup procedure). Here is how to install it on Fedora 11 from the command line: Download Pwytter, unzip it, enter directory pwytter-0.8 Install ImageTK: as root, type " yum install python-imaging-tk" ( in Fedora, ImageTK was renamed python-imaging-tk) Install simplejson: as root, type " yum install python-simplejson" (optional) launch: python setup.py build launch: python setup.py install Complete the installation by copying some files with the 4 lines below (type them as root too) ( a comment in pwytter blog helps to solve the pwCache installation bug): cp pwCache.py /usr/lib/python2.6/site-packages/pwytter-0.8-py2.6.egg cp pwCache.pyc /usr/lib/python2.6/site-packages/pwytter-0.8-py2.6.egg cp -r media/ /usr/lib/python2.6/site-packages/pwytter-0.8-py2.6.egg cp -r theme/ /usr/lib/python2.6/site-packages/pwytter-0.8-py2.6.egg Now you can launch pwytter from any user! In addition, since the source code is available and Identi.ca supports a Twitter-compatible API, let’s see if it’s easy to modify pwytter for Identi.ca :-) ...
IPGphor2reader is a software meant to parse log (text) files resulting from an experiment with the IPGPhor and to plot graphs. I previously hosted it on my personal website and just moved it to Sourceforge, here. Amongst the various reasons for this move, I wanted the possibility for anyone to participate in the project and no hassle to manage this. Slowly, slowly, most software on my website will be hosted on Sourceforge or Bioinformatics.net. ...
BioMed Central is one of the main Open Access publishers in the world of Science, Technology and Medicine. On a side note, that’s where I published my two articles (in Proteome Science and the Journal of Circadian Rhythms). One might think that, given their support to Open Access, they would also support Open Source software and Open Format documents. For the software side, it’s not very clear. Although they ask authors to consider releasing software described in publications under a free (or at least open source) license, they also support and advertise for a bunch of proprietary software. While it’s not a bad thing per se (it enlarges the number of potential authors), it’s sad to see they don’t cite popular free software like OpenOffice.org (to write your article), Gimp (to edit your figures) or Zotero (for reference management). These are the three main software in each category but the free software world has many more of them! ...
This week, I nearly emptied my internet quota by downloading and seeding the new Fedora Core 11. For those who don’t know yet, Fedora is a Linux-based operating system that showcases the latest in free and open source software. What I particularly like in this GNU/Linux distribution is that its developers prefer to make changes to the original software instead of applying fixes specifically for Fedora ; in this way, all the other distributions may also take advantages of the improved software. You’ll find many reviews and " tours" on the web about this new Fedora. In the next paragraphs, I’ll just highlight some of the most interesting points I saw until now. Coming from a Fedora 9 also helps to pinpoint the major improvements (mainly from a user point-of-view). ...
On the Bruxelles website, you can watch from and move a webcam on the Grand Place. The resolution is good enough to distinguish faces in you zoom. But what is more interesting (imho), is that the stream from the webcam is just a stream of still images from http://www.brucity.be/webcam.jpg. The image below was the current image from the webcam when you loaded this page ; reload the page to see another picture … ...
Being away from presentations to my dismay since a few months, I always enjoy reading the Presentation Zen blog, Garr Reynold’s blog on issues related to presentation design. Recently, Garr came back on the Ignite presentation style with a presentation from Pamela Slim. Here is a video recording: [blip.tv http://blip.tv/play/AfDpaI73Pw] I maybe liked this presentation for its content but above all for its style … At Ignite, you can have a maximum of 20 slides that automatically advance every 15 seconds (so max. 5 minutes talk). I like this kind of challenge. Unfortunately, there is no planned Ignite event in Western Europe soon where I would be able to watch this live. ...
Since I published some videos of Morris Water Maze (MWM) experiments, I received questions about the set-up of the maze and its concept in general. I tried my best to answer them. I collected them and here are the Frequently Asked Questions about the Morris Water Maze. If you have some more questions, don’t hesitate to ask!
Oracle and Sun announced a few days ago that Oracle will buy Sun. Others are more apt than me to comment on the financial and strategic impacts of this move (for example, in the Guardian, the New York Times, the Wall Street Journal or on Slashdot). I’m more interested in the potential implications this move could have on some Open Source projects which were backed by Sun. I indeed believe Oracle will continue the development of his contributions to Open Source software, whether they are notable ( Btrfs or Oracle Enterprise Linux) or less visible. ...
20040 views for my Gemvid presentation at FOSDEM 2009 100451 views for my random field presentation 200418 views for my OpenOffice.org Impress presentation It’s good to be considered as a presentation rockstar (even if it’s an April fools joke).
