An 'in' operator for Ruby?

I have had two fairly small changes I wanted to make in Ruby. The first was realized years ago -- hashes now preserve insertion order and iterate in a predictable way. That's fairly minor, but it did/does have some use cases, and it had no impact on performance.

Here's another one. Personally, this is a bigger thing to me.

Immutable data (ditching the wax tablet)

A couple of weeks ago, I went to Phoenix training prior to the Lone Star Ruby Conference in Austin. I was talking with Bruce Tate, and he shared with me some thoughts about functional programming in general.

Phoenix isn't Rails

I don't know Elixir very well at all. But I've started to learn Phoenix now. The first thing to know: Phoenix is not Ruby on Rails (nor is it "Elixir on Rails").

Ruby for Dinosaurs...

I have a good friend I've known since college. He was much older than I was (though now somehow we are much closer together in age). He was a mentor to me with regard to computers and other things.

Programmers and word processing

The other day, I was thinking about the mechanics of writing. Not grammar, spelling, and punctuation, but the actual work flow involved.

Specifically, I was trying to gather my thoughts on why writing a software book using Microsoft Word is so incredibly painful. (Granted, I have used Word or similar tools to write fiction and shorter pieces.)

It wouldn't seem so at first, would it? Isn't word processing software the savior of the writer? Wouldn't we be using typewriters without it?

Elixir Conf 2014

Last week in Austin, I attended the world's first Elixir conference. It was very energizing!
