Advent of Code 2020

Completed! I finished the Advent of Code for 2020, and this time pushed myself past the holiday indulgences to actually complete all 50 challenges! I pushed myself to use Elixir for everything this year, and barring a few small instances where being able to mutate a value would have saved me a lot of headaches (specifically this evil creation) it was a pretty awesome experience. Aside from the usual 2D grid geometry problems, there were a lot of new things in there and I discovered some nice things on the way.

Install referrer testing

Note: The broadcast referral functionality has been deprecated by Google Play and will be removed on March 2020. The new implementation involves connecting directly to the Play Store app - documentation is available at https://developer.android.com/google/play/installreferrer The install referrer is an intent on android, which is broadcast after the app install to give the app information about the reason it was installed. This is useful if you're tracking marketing / paid installs and you want to tell between paid and organic installs.

AnkiRB - spaced repetition flashcards made in ruby

In the past few weeks I discovered Omniglot and Anki and thought it'd be pretty cool to be able to create flashcards for the useful phrases listing. Being able to say “this guy pays for everything” in Turkish, or “my hovercraft is full of eels” in Norwegian could be an incredibly useful life skill. And so AnkiRB came into existence. The library basically replicates what the application itself does when you create flashcards via the gui, except uses ruby's sqlite package to create flashcards and bundle media files together.

Compiling C with Rakefiles

Make is solid. It's been around since before the internet and still one of the most important tools used today. As such - it's tried, proven, tested, and was used in some of the most successful projects out there. …but what are the chances that something so old got it right the first time? What are the chances that good old Make is the be-all, end-all, perfect ultimate solution for every possible development project?

How to write a bug report

Note: This is a post I created for internal distribution when writing bug reports for mobile applications. I'm sharing it here because I think it's useful for future situations. What's a bug report Bug reports exist only to inform people about software defects. They are not for notes, for tracking work done or for planning. There are better systems for this. The best bug reports will have as much appropriate information as possible to help asses get kicked as fast and effectively as possible.

2D OBB Collisions in XNA

OBBs (Oriented Bounding Boxes) allow for a greater degree of accuracy than their axis aligned counterparts in the field of collision detection. It turns out this is a lot simpler to implement in 2D than 3D. Here's my own take on it, which I hope to put to heavy use in an ongoing project. The OBB is modelled by an orientation matrix (in the form of two Vector2's because the Matrix type seems to suck), an origin and a Vector2 representing the +ve half widths in the x and y axis.
