What I did during AndroidConf Brasil 2011

Hey, reader! 

Today I was in the AndroidConf Brasil 2011 with some fellows. 

It was a good event. Not the best, nor the worst. A good one.

People who know me, know that I don't like cellphones. Then, since I'm not a proper example of enthusiastic about this topic, I tried to invest my time with an experiment. 

Last days I was trying to minify a javascript file by myself. I thought that would be as easily as count till 3. It turns out that I was wrong. I had to write a compiler in order to make it work well. Thus, I went back to the theory to see how it could help me.

As I was reading about automata and its uses, it turned out to be interesting to have a working example of the theory I was dealing with. And why not during the event? 

First presentation: git init. No wireless network?! That's ok. Thank you git!

There I was, writing a simple Deterministic Finite Automaton. 

Had a lot of fun doing that. 

Great saturday, =)

If you wanna see the resulting code -> https://github.com/cathoderay/dfa.

Need some rest now.

Till the next post!

pomodoro technique with arduino experiment

Today I decided to implement the pomodoro technique with my arduino.

It turns on an orange led (I didn't have a red one) from 10 to 10 seconds, just to remember me that I'm in a busy time, while a tic tac is reproduced by the buzzer.

After the first 25 minutes -- suggestion by Francesco Cirillo, the author of the pomodoro technique -- an alarm is activated. Then, a green led is turned on for 5 minutes -- so, I can rest a bit -- and the loop continues.

It's working pretty well, =)

The source code is available at my github -> https://github.com/cathoderay/pomoino/blob/master/pomoino.pde

Till the next experiment =)
