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

#    FasterCSV (ok, recommended)
#    ccsv (fast & recommended if you have control over CSV format)
#    CSVScan (fast & recommended if you have control over CSV format)

Design in the Small

• Don't design a Model to be coupled to an API
• Create a Service that talks to both your Model and the API

Service Wrapper Record

• You have services, stateless objects that talk to the application
• You have records, objects that talk to the database
• And you have Wrappers, a thin class for a narrow interface to an API
