BSides Lisbon and SECUINSIDE 2015 presentations

I guess my goal for the remaining 2015 of not doing any presentations will not happen. Two weeks ago I presented at BSides Lisbon 2015 and last week at SECUINSIDE 2015. I’m very happy to see BSides Lisbon returning after the first edition in 2013. Congrats to Bruno, Tiago, and the rest of the team for making it happen. It’s still a small conference but I’m glad they are making it happen, and I will always do my best to help the Portuguese scene going forward....

The updated version solves all required offsets so it supports easily new and old OS X versions....

The scale and dimension of everything in Beijing is quite a surprise. No wonder why every Western company wants to be there. We had great food and an awesome visit to the Great Wall. A big thank you to the boys and girls from the organization for all their hard work and dedication....

HiTCON 2013 slides

Taipei is definitely one of my favourite cities in the world! I love its “infinite” amount of small shops, in particular at night when lights are on. Streets look so beautiful and busy. Everyone is very friendly and respectful, and most important, I feel very safe. And the food is awesome (thank you Thomas!). I really love it! If you like Asia, Taiwan is a must visit. The only problem is language – English is not widely spoken....
