Bitocast - A hybrid BitTorrent and IP Multicast content distribution solution

Delivered and fininshed in January 2010 my Master thesis in Computer Science.

Master in computer science for Universidade Nova de Lisboa - Faculdade de Ciências e Tecnologia - Departamento de Informática

Abstract of the Master thesis:
In recent years we have observed an increased use of the Internet as a means for transmitting
large content. There have been several technology attempts to attack this problem, including
costly distribution networks and, more recently, peer to peer (P2P) protocols. Amongst
these P2P protocols, BitTorrent has proven itself as an effective means for transmitting large
content items and today enjoys great popularity.

Numerous researchers have analyzed BitTorrent and proposed concepts and models to enhance
its reliability, efficiency and fairness. Further, there are proposals to extend BitTorrent
to support on-demand multimedia streaming. In this Dissertation we present Bitocast, a
content distribution system that combines IP Multicast and BitTorrent protocols in order to
achieve a more efficient usage of an Internet Service Provider’s network and reduce download
time when serving large sets of contents to large audiences.

HTML5: A concorrência ao Flash dominante

Fui recentemente entrevistado telefonicamente para a Exame Informática de Julho, artigo “HTML5: A concorrência ao Flash dominante”
O artigo completo pode ser visto online  (pág 88). Claro que aquilo que dizemos é sempre um pouco alterado para o artigo, mas eis um excerto:

 

FarSeer in Microsoft Surface

Last year (2009) I ported Farseer physics engine to Microsoft Surface. With that I was able to do same demo projects. You can see some of the videos of the apps [1], [2], [3], [4]. One of these sample projects was even shown at the keynote of Microsoft Dev Days 2009.

Since several people asked me for the source code, I'm putting it here, available for download. It was developed on older versions of farseer and of Surface sdk, but I was informed it is still working under current versions. If you download and use it, please be so kind as to leave a comment.

I talked with the people responsible for Farseer about the possibility of having Surface was one of the platforms, but their response was:

genbox: "... I don't see Microsoft Surface being the next huge gaming platform in the near future. :) If I include it in the source tree, a couple of people might download it and have good use of it, but I would also have to maintain the code. Every time I change the API in Farseer Physics each change must be implemented into the samples too - We are simply too few people (and don't have the hardware) to maintain a huge selection of samples on different platforms."
