Avi — Thu, 17 Jun 2010 18:50:28 +0000

Horas depois do lançamento do iPhone 4, twitei sobre como seriam revolucionárias as novas capabilidades de VoIP do iPhone, batizado de FaceTime. Fiz questão de vasculhar a Internet para encontrar empatia naquela visão, mas aparentemente todos estavam facinados somente com o aspecto “videochamada” do aplicativo.

FaceTime é uma nova função integrada na aplicação de telefone [...]

I’m not an Apple fan but I tend to disagree with that campaign of Flash support.

Clearly, this is another platform war. The Apple platform versus the Flash platform. It is very strategic for Apple to keep [...]

A Media Center at Home

Since we got a 52″ Samsung LCD TV almost a year ago as a gift from relatives, I knew it was time to attach to it a dedicated computer and have a full digital media experience in the living room. I’ll tell you here my experiences building and running this thing that makes all my [...]

We made a point-to-point SIP high definition video conference over a local area network. Another test used H.323 protocol. We also included my SIP-enabled Nokia E61i in the conference over the office WiFi network in a direct multipoint call simply [...]
