Slightly disorganized but reasonably complete notes on the algorithms, strategies and optimizations of the Akka Cluster implementation. Could use a lot more links and context etc., but was just written for my own understanding. Might be expanded later.
Links to papers and talks that have inspired the implementation can be found on the 10 last pages of this presentation.

The HearSay P2P File Sharer; a response to The Copyright Alert System, as well as several other internet regulation attempts. The goal of this project is to prove the viability of semi-anonymous and confidential file sharing. Consists of several proofs of concepts such as the formation of ad-hoc mix networks and routing throughout them while maintaining anonymity and semantic security.
However, lets be honest with ourselves for a second. Don't use this to fight an oppressive regime. I can not (and will not try) to 'prove' its security, and I
I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.
I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real
