Stevey's Google Platforms Rant

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

There are two types (actually more, but for the problem at hand only these two are important):

• flat strings are immutable arrays of characters

• cons strings are pairs of strings, result of concatenation.

If you concat a and b you get a cons-string (a, b) that represents result of concatenation. If you later concat d to that you get another cons-string ((a, b), d).

Indexing into such a "tree-like" string is not O(1) so to make it faster V8 flattens the string when you index: copies all characters into a flat string.

Can NAT traversal be Tor's killer feature?

tl;dr: how about a virtual global flat LAN that maps static IPs to onion addresses?

[We all know the story][1]. Random feature gets unintentionally picked up as the main reason for buying/using a certain product, despite the creator's intention being different or more general. (PC: spreadsheets; Internet: porn; smartphones: messaging.)

The final result: require() any module on npm in your browser console with browserify

This article is written to explain how the above gif works in the chrome (and other) browser consoles. A quick disclaimer: this whole thing is a huge hack, it shouldn't be used for anything seriously, and there are probably much better ways of accomplishing the same.

Update: There are much better ways of accomplishing the same, and the script has been updated to use a much simpler method pulling directly from browserify-cdn. See this thread for details: mathisonian/requirify#5

The following is a partial annotated bibliography of SNI Mempool, building the case for why Bitcoin will displace all competing currencies, including altcoins, fiat money, and precious metals:

In terms of monetary policy, Bitcoin is the greatest money the world has ever seen.

• "Fractional Reserve Banking is Obsolete" by Pierre Rochard

Unsurprisingly, Bitcoin has gained substantial popularity, and there is no reason to believe it will not continue to grow. This growth is not merely a bubble.
