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

Bash

for file in prefix*; do mv "$file" "${file#prefix}"; done;

The for loop iterates over all files with the prefix. The do removes from all those files iterated over the prefix.

Here is an example to remove "bla_" form the following files:

bla_1.txt
bla_2.txt

Notes on teaching both test/unit and RSpec to new Ruby developers

@tenderlove asked "Is it good to teach RSpec (vs t/u) to people who are totally new to Ruby?" I have experience suggesting that it is a good thing; after a short back and forth, it seemed useful to write it up in detail.

Background

This goes back several years, to when I was the primary Ruby/Rails trainer for Relevance from 2006-2009. I'm guessing that worked out to probably 6-8 classes a year during those years. Since then, RSpec has changed a fair amount (with the addition of expect) and test/unit has changed radically (it has an entirely new implementation, minitest, that avoids some of the inconsistencies that made test/unit a bit confusing during the time I'm writing about here).

I started out as an RSpec skeptic. I've never been afraid of what a lot of people denigrate as "magic" in Ruby libraries … to me, if you take the trouble to understand it, that stuff's just pr

I'm puzzled by the behavior of take_while and drop_while when called without
a block. They return enumerators -- that part I understand -- but I'm not
understanding how those enumerators behave. 

Here's what I mean:

>> enum = [1,2,3,4,5].take_while
=> #<Enumerator: [1, 2, 3, 4, 5]:take_while>
>> enum.next
=> 1
