MSA book - let me send a buck overseas again as usual
I have read some books by this guy before and I cannot afford to miss this one - Kicking Butt with MIDP and MSA. While I know the majority of its content, Knudsen is always a good read in my opinion.
Linux Top Smartphone OS By 2012
I am sure Linux will increase its market share in the coming years...Maemo is maturing (and it is really open, not like the Motorola's Linux devices, which have closed environment), I bet we will have one device with more than Wi-Fi soon...

Going to BOSSA Conference 2008
Today I am going to BOSSA conference 2008, organized by the Nokia Technology Institute in Brazil. In my opinion, BOSSA is the the best mobile Linux and Open-source event in Brazil. As usual, it will take place in Porto de Galinhas, Pernambuco, Brazil but this time the venue is the Summervile Resort.

Technology professionals unveil their suffering - reporting from Brazil
This is about the average salary of tech guys in Brazil (in Portuguese).
A while ago when I was going to São Paulo for a business trip as usual, there were 2 guys beside me and one of them was the president of a company in Brazil. He has commented with the other guy that his annual bonus alone was something about 300K a year...I think I need to rethink my focus :)

The AAC, AAC+, eAAC+ audio formats
Nowadays everyone is buying a smartphone, or feature phone, whatever, you name it.
When I find friends talking about the memory space available on their mobiles and the MP3 thing, I always advise them to check if their phone can play the eAAC+.
I have hundreds of songs in my mobile today :)
Today the vast majority of good Nokia phones use it and I have explained it so many times that I always wanted to find a good (user) article about it. Here is the finding ;)
Sound start to music on mobiles
