Does this perform Paxos on every single transaction (wouldn't that be expensive?) or is Paxos used to elect a write coordinator replica and ensure a consistent view of the cluster to guarantee serializable consistency? If it's former, can w

Using a "magic marker" like this doesn't imply looking at a raw memory dump (which, however, is still needed in several places Google is involved e.g., kernel hacking, embedded devices). For example, I used it myself when debugging an issue

Most definitely! If it's easy to use, implies it must be easy to implement. Serious note: I think that it's beautiful that an untrained technical person thinks Amazon or Facebook could be built in a weekend. That's a testimony to the excell

No, you're not oversensitive here. I am. I regret putting that comment in. It's a visceral, emotional gut reaction. Nonetheless, I'll leave it there: editing it out would be Orwellian. However, there's an interesting point: they spent thei

Others have already listed good books. That's great, except I'd suggest spending time looking at data structures and algorithms books as well as software engineering and design books: a right data structure or algorithm can mean less code.
