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

Step 1

Identify what the business goal is for building software.

Business goal

Increase repeat sales to existing customers by 50% over the next 12 months

Step 2

From the business goal, derive the scope of the feature(s)

function prng01($min = null, $max = null){

        $max = PHP_INT_MAX;

What

A lot of times you are developing a web application on your own laptop or home computer and would like to demo it to the public. Most of those times you are behind a router/firewall and you don't have a public IP address. Instead of configuring routers (often not possible), this solution gives you a public URL that's reverse tunnelled via ssh to your laptop.

Because of the relaxation of the sshd setup, it's best used on a dedicated virtual machine just for this (an Amazon micro instance for example).

This is a more wordy, narrative accompaniment to my pretty bare presentation about d3 that I gave to the jQuery DC Meetup.

What is d3?

• Not a chart library (though you can make charts with it)
• Not a map library (though you can make maps with it)

Which is to say, d3 can be used for building things, but the 'atomic parts' are lower-level than bar graphs or projections or so on. This is a powerful fact. It also means that d3 is a good basis for simple interfaces, like Vega.js, that make its power accessible in other ways.

• Not a compatibility layer (it doesn't work with bad browsers)
