PeerSim, if you don’t know it, is a famous P2P networks simulator, written in Java. You can find its home clicking this link.
Surely, when you are writing in Java, it’s convenient to use Eclipse. In this article I will talk about how to configure eclipse to work with PeerSim. I decide to write this article mainly because I’ve founded some articles that talk about this integration; but I disagree with their solutions.

With the success of Ruzzle Solver, a lot of users have asked me to publish more informations about it. Some of them were interested to know more about it for an university exam. In this post, I will talk about some methods to realize this type of an algorithm. Surely, in the future, I will talk more about its implementation.

In AI, sometimes, you need to plan a sequence of action that lead you to your goal. In stochastic environment, in those situation where you can’t know the outcomes of your actions, a sequence of actions is not sufficient: you need a policy.
Markov Decision Process is a mathematical framework that helps to build a policy in a stochastic environment where you know the probabilities of certain outcomes.
In this post, I give you a breif introduction of Markov Decision Process. Then, I’ll show you my implementation, in python, of the most important algorithms that can help you to find policies in stocastic enviroments. You can fine a more detailed description of the Markov Decision Process in my my slides that I’ve used for a seminar at University.
A common problem, for people who create sites, is to create an elegant image gallery that manages the various sizes of images. Flickr and Google+ manage this situation in an excellent way, the purpose of this plugin is to give you the power of this solutions, with a new fast algorithm.
Some month ago, I wrote a WordPress plugin that shows a Flickr photostream with a justified grid. Now, I decided to do a more abstract plugin (jquery plugin) that can be used everywhere!
See all the documentation in its project page. Or download it from github.
Hi! I just put online again the Miro Rubix game for PC and for PSP! A simple puzzle inspired by the famous game called Rubik’s Cube. The puzzle starts with two equal pictures where only the left one is mixed in various boxes. Moving the columns and the rows of the left one, you just have to form the picture on the right. The game comes with few puzzles. Some puzzles are classic, they contains only boxes with few colors; the other was created using various photos. But, you can create your own puzzle with your own photos!

My first WordPress Plugin has just been released!
Plugin that allows you to show your Flickr Photostream in your blog. Awesome thumbnails disposition with a justified grid, with a Javascript algorithm, for a fast redraw. Various settings to configure the height of the rows and the behaviour of the last. You can show photos with a lightbox, or with a link to Flickr. You can configure the number of photos per page, then, you can navigate between various pages. You can configure the plugin to create fixed height rows or to create rows where the height depends on the images. The plugin chooses the right resolution for the image, using the Flickr size suffixes.
Hi! I use Flickr to share my photos, and I know that Exif data are normally considered as “sensitive data”. For this reason, I realize a simple bash script that removes all Exif entries only leaving the most importants.
Continue readingI’m writing an application in C# that needs to know if the system time is not fake (only if the network is on). For this reason, I make a class that retrieves the time from a NTP server. The class is written to prevent that the same servers are called too often using a simple circular array. For the data returned by the servers, I invite you to see the RFC-2030.
Continue readingFinally, I release my first version of MExpr library!
A C++ Library that parses mathematical expressions. The library is made using bison and flex. Evaluation on AST Tree browsing it recursively. Ability to compile it in a bytecode that uses a stack to evaluate the expressions. Support to variables. Support to implicit multiplications like -3xy^2. Support to functions and overloaded functions. Set of standard functions taken from math.h
I post you my simple class to shutdown, reboot and logoff Windows using the famous ExitWindowsEx. Each method is overloaded with another that force the action, in other words, it executes the action without prohibiting Windows to send the WM_QUERYENDSESSION message. With the latter way, the user can’t cancel it.
