I’ve just uploaded a new project on Github called delicious_wp: it’s a small Ruby script that simply fetches the items stored in del.icio.us the previous week and creates a blog post with them. You can set up a small cron job to execute this script every week, which is what I’ve done for this blog [...]

Wow, that’s a long title, but it should drive people with this problem right here. If you have upgraded your WordPress installation to 2.8, you might have encountered a nasty error in your Dashboard, which says something about a
Fatal error: Call to a member function on a non-object in /home/user/www/wp-admin/includes/dashboard.php on line 647

Now that the NDA on the iPhone OS 3.0 SDK has been lifted (which happened much faster than what I thought it would take!) here’s my first contribution to the world of iPhone OS 3.0 open source code: sample code about how to use OpenGL ES 2.0 on the iPhone 3GS, something I announced in [...]

You might remember my beloved mantras: learning a new programming language and reading at least 6 relevant books every year. Following the 2007 edition, here’s the list of the 8 books I have enjoyed most in 2008, ordered by a purely subjective and absolutely irrational decreasing preference.

Software Engineering is the youngest of all the professions, being born around 50 years ago, but since then it has been continually improved. Practicers have fiercely debated upon it through the years, given the extremely fast pace of the innovations in the field, and the extremely difficult and inherently dynamic nature of software. Many trends [...]

On Mac OS X, I installed it via MacPorts using the all-time classic:
sudo port install ImageMagick
Then I [...]

I’ve just installed the excellent wp-super-cache plugin to accelerate things a bit in this blog; today somebody sent one of my pages to reddit and I’ve had more users than usual! – by the way, thanks for coming! :)
Update: I admit, it also has a bit to do with the reading of today’s entry in [...]

This is the documented path to my discovery of PostgreSQL 8.3, which I’ve never used before. Now that MySQL’s community is getting hammered to death by Sun, and thanks to all the good things I’ve heard about it over the years (including enhanced performance on multicore systems and greater scalability), I really wanted to install [...]

I’ve just had a very interesting conversation with my colleague Marco about different approaches to the organization of code inside a Django application.
As you might know (and if you don’t I’ll tell you anyway), Django’s views (somehow occupying the “Controller” level in an MVC architecture) must take (at least) an HttpRequest instance as a parameter and must [...]
