Some time ago, I read some books about a boy who stops some evil dude using a supercomputer made of brains from planet populations or something like that. It later turns out that this evil dude was selling information to spacefaring civilisations and used these brains to solve alien questions. The protagonist helps some aliens, and later, maybe in the second book, he is traveling with them when they are attacked, and he uses an evacuation pod, ending up on some planet where he joins some mercenaries. There, he helps in some space battle, affecting the outcome. After he rejoins the first set of aliens, he disarms a nuclear bomb in some court. There is also mentioned somewhere that, sometimes, some civilisations experience sudden change, a techonolgy leap, or "ascend".
