The black hole…
I confess I have some admiration towards the Mono Project. It is the base of different tools, and it allows those tools to run virtually on any device. A good example is the Unity 3D Game Engine. In my teaching duties this year I need to each MonoGame. Not sure if this is a good […]
Cross Posted from my Perl Blogs blog. So, yeah, to make me more active in the Perl community I decided to join the Pull Request Challenge. I have a quite big number of modules to maintain, but sometimes it is good to look to some other people code to learn something. My attribution for January […]
In the last two days I engaged in developing Reversi, just to learn how the minimax algorithm works. To make it easier to share, and remove GUI toolkit dependencies, my approach was using HTML (a simple page with a 8×8 table), three images (empty cell, black or white cells), a CSS file that fills empty […]
I can’t see how people say Java is an end-user language, whose applications are for general user usage… SEVERE: Exception javax.xml.transform.TransformerException: org.apache.fop.fo.ValidationException: “fo:inline” is not a valid child of “fo:block”!

This year I am teaching Artificial Intelligence for Games. I grabbed some book PDFs from the Internet (yes, sorry, it would be impossible to buy all the books to choose one, and libraries around doesn’t have books in this thematic) and I chose a pair of books to buy. One of them is this Artificial […]
Probably this is a stupid rant/question. If so, please clarify me. I can live without the insults. Really :) OK, on to the relevant stuff. Twitter has a new OAuth authentication mechanism. To write an application able to post on twitter your application need to be registered and have a consumer key. That key is […]
If you know me, you know that I program mainly C and Perl, that my preferred editor is Emacs, and that I use mostly Mac OS X for that task. But, I teach programming, and sometimes I teach programming to students that never heard of Linux or, worse, that never used the command line of […]
I teach XML, DTD and the like, and I teach (or show and make students use) CSS for XML. It doesn’t work properly on all browsers, it doesn’t work consistently on all browsers, it doesn’t do everything web publishing needs. But it is a good approach to add some style and usefulness to XML without […]
I posted some time ago about Pascal, and the nice (and worst) things that Pascal has in its language. I discovered yet another cool thing. Unlike C, where you can pass parameters to functions by value, or using a pointer (and therefore, as reference), in Pascal you can use a value, you can use a […]
As I posted before, I am teaching Pascal. I could discuss the relevance on teaching this language in this decade, but that is not my concern. I would like just to point The Good, the Bad and the Ugly I find in Pascal. The Good: Pascal evolved and is a high level language. You have […]
