This is cool. I used to prefer PostgreSQL/Postgres over MySQL, but guys at my company preferred MySQL. I’m glad to see Postgres is still around. Here’s a link to the story on ReadWrite.

Scala FAQ: What is the difference between Nil and List() in Scala?

Short answer: There isn’t any difference, as shown in the Scala REPL:

scala> Nil == List()
res0: Boolean = true

It’s more “idiomatic Scala” Scala to use Nil rather than List(). For instance, I wrote code like this last night using Nil in a Scala match/case expression:

“What is an I/O Action?" From the book, Real World Haskell.

Wow, the following code might be the largest Scala SBT build.sbt configuration file I’ve ever seen. It comes from this project.

Here’s the build.sbt file contents:

I received an email from the O’Reilly folks stating that they’re having a sale on “Top 25 five-star” eBooks and videos (including the Scala Cookbook). Here’s a link to their sale.

“The difficulty lies not in the new ideas, but escaping from the old ones.”

I just learned about the Atreus curved, wooden keyboard from this tweet.

Summary: In this article I share an approach I used to make a condensed version of a PDF book by printing only the first two sentences of each paragraph in the book. In the long term I hope this will help me create a “CliffsNotes” version of the book.

At the 2014 Buddhist Geeks Conference, Mikey Siegel offered this “thought exercise” on the end game of the Meditation+Technology movement. That is, if everyone was incredibly successful with the all the new technology efforts, this is as simple as “enlightenment” can possibly be. (I don’t know if you can achieve enlightenment without effort, but I suppose this is an ideal.)

I was reminded of the ”Joel test” when I looked at this “Notion” job posting in Denver, Colorado. (If that description said “Scala” instead of Ruby, I’d be all over it.)

When I lived in Talkeetna, Alaska, I quickly learned that a constant supply of electricity was not a fact of life, as this story about ravens and beavers bears out.

Folks in Anchorage, Alaska got hit by up to nine inches of snow today (October 20, 2014). Photo from this Twitter page.

As a short note, I like the “add one event at a time” UI widget in the Mac OS X Calendar application. There are some other things I don’t like in the Add New Event UI, but I do like that concept, even though it is a little hidden.

Wow, from this story on Bloomberg, IBM is paying more than $1.5B to get out of the chip business. For me this hits home because I remember that IBM thought the PowerPC chip would be a competitor to Intel’s chips back in the day.

Why it’s hard to get home delivery in Alaska. :)

They started tearing down the bleachers in Wrigley Field today as part of the big renovation. More photos here at the Chicago Tribune.

I just learned that Alaska’s own Marian Call will be playing in Boulder, Colorado on October 29, 2014. I’m in.

I’m always surprised that people don’t double-check headlines.
