A memory glitch

This is not a technical note. It is about myself.
I revoked a situation, an image from my memory. It was sometimes when I was 7 or 8 years old. I went to the bed but I took some kid books with me and I was reading those poems again. I was in the same body position as when I am reading datasheets at late night today.
Amazing! That means I showed a tendency to read and learn everything interesting. I can remember the hunger for information in that evening as I planned which parts will I read again, on my own.
Bad luck that time when I woke up I realized that I did not finish reading all the books I wanted to.
Parents! Support your children's abilities! Pay attention to them!

Mario has a PICMicro hacking blog. Security issues of MCUs are discussed here.

So my first rant will be about SMD TQFP soldering.

I added some pictures to the discussion (link below) and I hope it will help some people who got the SMD soldering mental block. I really don't see any problem with any SMD once you get to learn to use tool BIG enough, not SMALL enough to do that. What am I doing is not work of little dwarfs on the PCB, it is the same work that is done by some real large SMT soldering station.
Soldering and desoldering of large SMD TQFP chips is described below:

Enough! pictures speak for themselves.

Well, the discussion evolved into ranting about some 20T Bitter magnet (after Francis Bitter), which can now make peak some 60T only ;).
