'Amazon's Alexa Has 80k Apps and No Runaway Hit'

I read the headline of this article, and immediately had some thoughts:

I saw this coming a mile away, and I don’t know that there will ever be a “killer app” for these devices.

  1. Discovery: Installing the apps is relatively inconveneint / out of the way
  2. Usability: Using them is awkward (“Alexa, tell <app> <thing>”)
  3. Recall: An audio-based interface gives no opportunity to prompt you that an app you’ve installed even exists
  4. Crapflooding: A gold rush can drown out the gems.

Pitfalls of a Monorepo

Getting At Awkward Code, For Great Testing

A couple days ago, I wound up helping out a colleague on a problem he was having coming up with an appropriate test case for a piece of code in a Rails app. It reminded me that I had wanted to talk about how structuring your code affects what you are actually testing, and how that related to what you want to test.

Pathfinding in Unity

When it comes to pathfinding in Unity, you can roll your own, or use one of two publicly available resources. The most drool-worthy is AngryAnt’s Path. Having gotten way too familiar with the problem of pathfinding myself, and wanting a better workflow and richer capabilities than my home-grown solution affords me, I decided to poke around with AngryAnt’s code last night.

License of UnityUnit

I was asked today about what license UnityUnit is released under. Since I didn’t explicitly state the rights and terms one can’t reasonably assume that it is safe to use it! So, I am officially noting that all versions of UnityUnit to date are released under the BSD license. Enjoy!

Unit Testing in Unity

Until now, there has been no good solution for building unit tests for games built using Unity. As of today, there is. Get the package (version: 20090704) here.

Ruby on Rails and Performance. An Interesting Experience.

I was out sick yesterday, but I managed to spend a little time working on “SB”. I’ve been playing with Ruby on Rails for a couple months, but today I really began to grok where the limits are with respect to Ruby, Rails, and performance.
