Spam, Spim, Spit!

Looks like the three magic words to open the secret door? Well it’s not. We all know SPAM for as long as we remember E-mail (maybe not me, I still remember receiving E-mail by UCCP by X.25 and using those long easy to remember NOT path!host!user addresses). More recently SPIM has been attacking the MSNs and ICQs of life. But now, in the year of VoIP massification, Pedro found in a great article from the security master Bruche Schneier that a new form of E-abuse was created: SPIT (Spam over Internet Telephony). Be afraid, be very afraid. What kind of Anti-SPIT software could be created?

Um Sábado diferente: Saltar de um Avião

Brutal. Peguem na experiência mais aventurosa que tiveram (para um indivíduo que se situe dentro dos padrões standard da normalidade, claro seja), multipliquem por dez e não vão chegar nem perto à sensação que eu tive ao saltar de paraquedas de um Cessna com a cabine aberta a 4000 pés de altitude pela primeira vez…

UML tools for MacOSX

For those of you who, like me, just out of curiosity are looking into non-java/non-bloated UML tools for your MacOSX to check on your next free time slot because you think the concept is great but the real life benefits are questionable, Rui Carmo wrote a nice article on Tao Of Mac and pointed two interesting programs to look into.

The Blogging phenomena

As a newcomer to the blogging world that I am, and after some basic lessons I had about the way this community works I must say I’m very impressed with both the technical and social movement around this phenomena. Although I’m the Internet business, yes it never got me so obvious. It’s really the way information should be created and exist and there’s no stopping now, you big media corporations and so called opinion benders – be afraid!

Blogging has influence in the Elections, Search engine results, it irritates the so-called “Real Journalists“.

This led me to the subject of how the Web and the whole content distribution thing would be so great if it wouldn’t sit on a server/client model. BitTorrent and eDonkey already have about 70% of the whole Internet traffic .

They’re already using Peer-2-Peer to distribute live media (see: P2P-Radio or Peercast) but where are those BitTorrent2HTTP gateways that we’ve seen promisses of in the past ?

iChat and Jabber. XMPP reverse engineering.

iChat and XMPP/Jabber

Well it’s weekend and I decided to waste some time on something cool (“waste” is not exactly the term as working with Jabber is part of my professional activity, but I sure could find something more useful on my top_pri_todo_lst.txt, but not as fun).

Ok 29 of April has finally arrived, Tiger was unleashed and I just love it. One of the most exciting new features is iChat support for the Jabber protocol (aka XMPP). Since XMPP support was announced on Tiger a few months ago, I’ve been most curious on how would they implement it and which JEPs would they support, if any.

I sense that…

Google’s non-evil company perception era has ended. Really.
