Not magic, just a different kind of science.
I had to cache the results a couple methods recently, and only after I had done it a few times, I realized I should just write a memoization extension for System.Func. public static Func<T, TResult> Memoize<T, TResult>(this Func<T, TResult> func) { Dictionary<T, TResult> dict = new Dictionary<T, TResult>(); return input => { if (!dict.ContainsKey(input)) […]
MoreLoyal followers! I'm not dead! In fact I've been working away on a few cool projects, but I'm not quite ready to divulge. Anyway, I thought I would post about a few different resources I've been reading through lately: A Conversation with Anders Hejlsberg You have to read every word. Seriously, stop reading this […]
MoreOn any engineering team, it's sometimes difficult to agree on best practices. Everyone has different ideas of good style, consistency, etc. But there's one thing we've reached consensus on: enums. Here is what our best practices say an enum definition should look like (keep in mind, this is only for int valued enums): public enum […]
MoreI use PHPStorm for all my JavaScript needs. Dang it's good. Anyway, I've been working on a secret JS project I'll hopefully share one day, and one thing I've been working on is my JS file template. There's not a lot to it, but this is what mine looks like: 1 2 3 4 5 […]
MoreI had a few ideas for C# constructs, so I thought I might as well write them down. Perhaps, some day, someone can tell me why these don't exist... Making Generics More Generic Several times I've been frustrated by the fact that Func<TResult> has a bunch of variants. Wouldn't it be cool it you could […]
MoreI recently wanted to curry a Func (and variants). Here's how I ended up doing it: public static Func Curry<TCurried, TResult>(this Func<TCurried, TResult> fn, TCurried arg) { return () => fn(arg); } public static Func<T, TResult> Curry<TCurried, T, TResult>(this Func<TCurried, T, TResult> fn, TCurried arg) { return param => fn(arg, param); } public […]
MoreIf you have an array of values, how can you take the sum of any range of them in constant time? With a sum table! Here's a formal definition: Given a list of values , then a sum table is a corresponding list such that . That is, each value in the sum table is […]
MoreUpdate: The source can be found on GitHub. In part one of this thrilling diptych I unveiled my beautiful classic noise function on the world using many many lines of someone else's code. Well in this post I hope to further bedazzle you by actually using that noise function-- and even some of my own code. […]
MoreUpdate: Part II of this post can be found here. Update 2: The source can be found on GitHub. Where to begin? As a previous post pointed out, I've been working my way through "Texturing and Modeling: A Procedural Approach" and it's blowing my dang mind. For instance, did you know that Scorched Earth is […]
MoreIn my previous post, I described a process for generating terrain on a spherical mesh. As the screenshot showed, the algorithm worked pretty well to give you a lumpy looking planet or asteroid. But-- what if you want it to look like Earth? Green continents, blue water? You know the Earth I'm talking about. Well here's […]
