Elixir installation guide

Version numbers should be the ones you want. Here I do it with the last ones available at the moment of writing.

The simplest way to install elixir is using your package manager. Sadly, at the time of writing only Fedora shows the intention to keep its packages up to date. There you can simply sudo dnf install erlang elixir and you are good to go.

Anyway, if you intend to work with several versions of erlang or elixir at the same time, or you are tied to a specific version, you will need to compile it yourself. Then kerl and exenv are your best friends.

Kent Beck - Paint Drip People

Keith Adams worked on kernels at VM Ware. Then virtual machines. Then search performance at Facebook. Then the HHVM implementation of PHP. Then machine learning. Now he’s Chief Architect at Slack. In between he worked on hundreds of little projects that lasted hours or days or weeks. Keith is a Paint Drip Person.

I was a big fan of the T model of skills, introduced by David Guest in 1991: know about a lot of things, be really good at one. The more I taught it, the more unhappy I got with the metaphor:

• Skilled people are good at several things.
• Skilled people’s interests develop over time.
• Skilled people don’t plan their next focus area. Sometimes it seems completely unrelated to their previous focus area.

Safari iframe cookie workaround

Safari by default discards cookies set in an iframe unless the host that's serving the iframe has set a cookie before, outside the iframe. Safari is the only browser that does this.

The 10k foot view

In order to get around the issue, the parent (src) and child/iframed/remote (dest) site have to work together, if the source site only wants users to access the destination via the iframe and can't assume that the user has visited the destination host before.

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
