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 [...]

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 [...]

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.

However, the current ohcount distribution (which you can download from this link) does not build out-of-the-box in Leopard. [...]

It’s fun to find out how to tackle the same task in different programming languages; in this case, it’s all about doing HTTP requests over a network: fortunately, there are networking libraries in virtually all major programming languages. In my current project, I’m generating wrappers easing the access to the core of the project itself, [...]

There’s an interesting discussion going on these days on Ruby blogs about, basically, how to avoid one of the most common, annoying, easy-to-create bugs in any programming language: calling a method on a null reference (or pointer, depending on your language).

This single issue happens all the time, in garbage-collected and non-managed languages, static and dynamic, [...]

I’ve just uploaded a new version of my Delicious Library to BibTex Converter, which might fix some issues for some users. Thanks to Hernun for the testing!

Introduction
I have been working as a software developer since 1996, and as such I’ve used a variety of different languages, both compiled and interpreted. But the who languages that I know and use most today, are two somewhat different ones, C# and Ruby. I will begin my presentation with a short explanation of both, providing [...]
