The application is very simple, and in fact reminds me of a very limited type of Turtle Graphics.

I heard recently about an interview problem involving matching braces in a string. Checking to see if all the braces in a string are paired up in the proper order. Seemed like an interesting, and short, challenge.
Examples of strings with proper brace matching:

It’s spoiler time for the upcoming Magic: the Gathering set. During this time a lot of images get posted to reddit. Unfortunately a lot of people can’t see those images because magic.wizards.com is blocked for them. Imgur however, often is not. I happen to be one of those people.

Then I’d check the comments to see if anybody re-posted it on imgur, most of the time nobody had.
I figured this would be a good opportunity to try to create a bot that does just that!

Recently I got an idea for a mobile app which has sparked my motivation to learn how to make apps for Android. So I headed to the developer page and downloaded Android Studio. It’s been so long since I attempted programming anything for Android, the last time I did it was still done with ADT and Eclipse. So I’m pretty much starting at square one here. Unfortunately I ran into several problems just trying to get a simple “Hello World!” app to build and run. I could probably write a post just about setting that up.
The first test program I wanted to do was to try reading data from a website. The front page of Reddit seemed like a good candidate, so I went for that.
