One benefit of using immutable values

When your values are immutable you are often forced to use a declarative style. This means you express what a value is, rather than imperatively building it up.

For example:

results = []
for x in values:
    results.append(func(x))

This common style of imperative code may seem simple at first, but when you read it, you as the reader must mentally construct a state machine and step by step reason about the state of mutation on each line.

"Vendoring" is a vile anti-pattern

What is "vendoring"?

From a comment on StackOverflow:

Vendoring is the moving of all 3rd party items such as plugins, gems and even rails into the /vendor directory. This is one method for ensuring that all files are deployed to the production server the same as the dev environment.

The activity described above, on its own, is fine. It merely describes the deployment location for various resources in an application.

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
