Thesis defense

February 18, 2010 English

Today was a very important day, as I finally defended my Phd Thesis under the title “Resource Optimizations in Broadcast enabled Networks”.

I was probably a bit nervous as the defense was about the start, as shown in the above picture. The defense started with a 30 min delay, as one my jury member was held in traffic. But in 2h30m time I would be out of the room with boosting confidence levels, as I had finally successfully completed one my most important milestones.

Today I concluded a path, which started 5 years ago when I accepted the challenge of my supervisor to conduct research in an area that was then not very clear if it would become the next hit or flop in Telecom. Today we have very successful IPTV services and operators that cover several technologies (which include broadcast) under a single service platform.

I don’t think my research work in the area is done, far from that, I still believe much needs to be done and changed in the Telecom industry in order to survive in this century without becoming a fossil. But I leave all my new ideas to projects to come

Where is the symbian store?

September 23, 2008 English

So I’ve had a Nokia E51 for less then a week, and all I can say is:

“Where is the symbian store ?”

Compared to the Apple Store where I can get tons of applications for my iPod Touch, or the recently announced store announced by google for TMobile’s G1 Phone announced today, the symbian platform definitely lacks a centralized gathering point for all the software available out there.

For a newcomer such as myself, the task of find applications that fit our needs is too high when compared with the competition, and I don’t think of my self as a tech savvy person…

And then again there is something called MOSH, a sad excuse for a community based store that would do better for nokia if it was actually not maintained by the community.

New (old) Cellphone

September 21, 2008 English

After less then a year of usage my SE w580 has failed me… the cursor right key doesn’t work which makes it pretty hard to navigate in the main screen and to write sms with symbols and using T9.

Luckly enough my father had a Nokia E51 hanging around the house since he bought an iPhone, which I’ll be using for the next time being

That to say until one of the following things happen: I buy my self an iPhone, I get my w580 fixed, the Nokia too fails.

Now what can I say about the Nokia E51 ?

• It’s light (although bulkier then the SE w580)
• Being my first Symbian phone, I’m still getting used to hit but is something that is slowly growing into me…
• It’s 3.5G (which makes it more usable for internet services such as handivi - by the way I intend to review their service in the near future)
• It has everything I asked for in a cellphone, so I’m pretty much happy with it

I can say that my team did a good job and to show their good work we have created a video for YouTube.

Telecom API’s

May 12, 2008 English

The Telecom Operators that relied in voice services are dead. And today’s operators fight for their own existence in a world dominated by the Web 2.0 where services can be created, combined in matter of day’s if not hours by limited resources teams. This new playground poses several challenges to telecom forums that have in the last years devised several API’s for enabling developers to plug in to their network. The following table has the particularity of synthesizing what’s going on.

This table has been adapted from here

IMHO we are going the way of SIP-Servlets. The reason ? From all of the options it’s the easiest! and that has been the rule of thumb for all the Web2.0 developments.
