Presentation at Dallas Scala Enthusiasts

Here’s a presentation I made recently (4/9/2015) for the Dallas Scala Enthusiasts meetup group. I attended Scala Days 2015 in San Francisco and presented the notes I took while there.

I wasn’t trying to be a substitute for going to the conference, but I realize most people aren’t able to attend and I could provide some guidance of which presentations are worth following up with. Since the presentation the videos have finally gone live and are available at Parleys

A note on my presentation style: This is the second presentation I’ve made using Remark.js and hosted on Github Pages and I plan to keep using this setup going forward. I’ve found this to be a quick way to put a presentation together and easily host and distribute it. I’m happy with the tradeoffs of making a decent looking presentation very fast with all of my content in markdown. Also, if there’s demo code (like there was last time), I can keep the code and the presentation in one location.

Scala-Format package

I fixed some issues with my Scala-Format package for the Atom editor. Please upgrade to 0.1.4.

Atom updated their API and removed some of the methods I was using, so I had to do some minor refactoring.

Nodeschool Dallas : git-it

I’m one of the organizers for the Dallas chapter of Nodeschool. We are going through the git-it workshop at our next meetup .

As always you can come work on whatever workshop you want, but all of the organizers have already done git-it in advance, so we’ll be there to help you.

Implicitly Yours

I recently presented at the Dallas Scala Enthusiasts meetup on implicits in Scala.

My presentation can be found here and the code can be found in the associated Github repo:

Recent commits:

additional code created during the meetup, Steve Gangstead
11th hour update, Steve Gangstead
more round corners, Steve Gangstead
citations were needed, Steve Gangstead
much more slides, Steve Gangstead

Here’s some sample code from the slides so this post looks interesting:

implicit val n: Int = 5

def add(x: Int)(implicit y: Int) = x + y

add(5) // takes n from the current scope
add(5) (1) //can always call explicitly

I had a lot of fun making this presentation and switching back and forth between slides and code. I really liked making the slides in markdown with Remark.js and hosting the slides in the same repo as the code.
