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

Ecto Soft Delete

Soft Delete Ecto Repo

The goal is to support soft delete functionality in Ecto.Repo. With the suggestion by @imranismail, another repo is created and the remaining functionalities are delegate to the original MyApp.Repo.

The new repo get/2 and all/1 functions will exclude the soft deleted record by default. delete/1 and delete_all/1 will update the delete_at column by default instead of deleting.

Example

MyApp.Repo.get(MyApp.User, 1) //will return nil if record is in soft delete state
