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

Colours in terminal

It's a common confusion about terminal colours... Actually we have this:

plain ascii
ansi escape codes (16 colour codes with bold/italic and background)
256 colour palette (216 colours + 16 ansi + 24 gray) (colors are 24bit)
24bit true colour ("888" colours (aka 16 milion))

printf "\x1b[${bg};2;${red};${green};${blue}m\n"

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

	#!/bin/bash
	exec {times}> times {typescript}> typescript < "${1-/dev/stdin}"
	while read -r; do [[ $REPLY = ' "stdout": [' ]] && break; done # skip to this line
	LANG=C
	printf "Script started on %(%c)T\n" -1 >&"$typescript" # dummy
	while read -r open; [[ $open = '[' ]]; do
	read -r elapsed; read -r string; read -r close
	eval printf %b%n "$string" characters >&"$typescript" # put count in $characters
	printf "%s %s\n" "${elapsed%,}" "$characters" >&"$times"
	done

	{ config, pkgs, ... }:

	{
	imports = [ ./default.nix /root/nixcfg/core.nix ];
	services = {
	example = {
	enable = true;
	};
	};
	environment.systemPackages = with pkgs; [ wget tcpdump ltrace gdb ];

	defmodule Curried do
	defmacro defc({name, _, args}, [do: body]) do
	curried_args = Enum.map(Enum.with_index(args), fn({_, index}) ->
	Enum.take(args, index + 1)
	end)
	for a <- curried_args do
	if a == Enum.at(curried_args, Enum.count(curried_args) - 1) do
	quote do
	def unquote(name)(unquote_splicing(a)) do
	unquote(body)

	defmodule Curry do
	defmacro defcurry({func_name, _func_ctx, args}, do: body) do
	num_args = Enum.count(args)

	if num_args - 1 >= 1 do
	new_args = Enum.take(args, num_args - 1)
	quote do
	def unquote(func_name)(unquote_splicing(args)) do
	unquote(body)
	end
