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 [...]

Historically, we can distinguish really big software companies for providing, at least, four major kinds of products: an operating system (sometimes open sourced at a certain level), a web browser (with various degrees of standard compliance), a suite of office applications (slightly compatible with everyone else’s), and a programming language with curly brackets (generally incompatible [...]

Yes, it’s possible. Even if Objective-C is one of my preferred programming languages, in any case I think it’s worth mentioning that, 2 years after the official iPhone SDK has been announced, the iPhone development landscape has really grown up, and many, many different options are available today. This article provides a very high-level enumeration [...]

I love playing with iPhone URL schemes. And if you ask me, just like for Mail.app and Safari, I think there should be a “default” Twitter client URL scheme in the iPhone, with an interface in the Settings application allowing you to set the application that you prefer to tweet. Alas, this is not the [...]

The first iPhone application under the akosma brand has just been published on the App Store:
bluewoki is a very simple walkie-talkie application, which uses the new GameKit framework available on the iPhone OS 3.0. It is available at the App Store! In English, Spanish and French.
The source code is really simple (around 170 lines [...]

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
This has been [...]

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 [...]

This is one of the most common scenarios for network- + UITableView-based applications; a UITableView instance whose contents come from the network; not only the text, but also the images! Somehow we all want to reproduce the behavior of the App Store (or of the iTunes) iPhone application, where the icons (or covers) of [...]

No, not a comic strip nor anything else that uses the “strip” word. But rather this component which lately has appeared in many different iPhone applications (see below some screenshots from the Facebook, the LinkedIn and the TSRinfo ones), and which I simply reimplemented, and then posted the code to Github for everyone to enjoy [...]

ImageMagick is a cool toolkit; not only it’s a complete set of command-line applications, ported to Windows, Mac and Linux, supporting hundreds of different image formats, it’s also a C++ library that you can use in your own applications!
On Mac OS X, I installed it via MacPorts using the all-time classic:
sudo port install ImageMagick
Then I [...]
