Simple iTunes AppleScript script examples alvin June 28, 2016 - 10:00am

If you’ve never used AppleScript, here are two iTunes AppleScript examples to get you going. First, This one tells iTunes to play the playlist named “My Favorites”:

A gallery of 130+ Gimp filters/effects

There are times when I work on images a lot with Gimp, and then there are times when I don’t work with Gimp for a month or two. When I don’t work with Gimp a lot, I tend to forget about all of the different things I can do with. Therefore, I have created this page as a “Gimp special effects cheat sheet” page to help remind me of all the cool things I can do with Gimp effects.

An introduction to Scala Types (from the Scala Cookbook) alvin June 21, 2015 - 1:14pm

This is an excerpt from the Scala Cookbook (partially modified for the internet). This is the introduction to Chapter 19, Types.

When I wrote the Scala Cookbook, I gave each recipe and then each chapter my full attention. I thought that if I wrote each recipe as well as possible, and included important recipes in each chapter, well, I wanted each chapter to be worth the price of the entire book. That was my goal.

As a result of this effort -- and perhaps to the chagrin of my editor -- the Scala collections chapters ended up being 130 pages in length.

Play Framework Recipes alvin August 2, 2013 - 10:25am

Here’s the cover for my new, free PDF, Play Framework Recipes. (I obviously didn’t put much work into the cover, lol.) As the title implies, the book is a collection of cookbook-style recipes for the Play Framework. The book is about 80 pages in length, is currently available as a PDF, and will soon be available as a Kindle eBook. Here’s a link to more information on Play Framework Recipes.
