Not magic, just a different kind of science.
Virtual. It’s a language feature that I’ve decided I have understood incorrectly for awhile– but it’s not completely my fault… See, a large part of my professional career has been in Java Land where the virtual mechanism is a quiet little assumption sitting off by itself in the corner. All methods are virtual by default […]
MoreOnly the finest material makes it to thegoldenmule’s Reading Roundup series. This time, I even included a video for you folks that can’t read! Predicting the Future, by Alan Kay http://www.ecotopia.com/webpress/futures.htm This is the one where Kay famously says, “the best way to predict the future is to invent it.” And it’s brilliant. I […]
MoreI 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 Memoize(this Func func) { Dictionary dict = new Dictionary(); return input => { if (!dict.ContainsKey(input)) { dict[input] = func(input); } return […]
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: /** * Author: thegoldenmule * […]
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(this Func fn, TCurried arg) { return () => fn(arg); } public static Func Curry(this Func fn, TCurried arg) { return param => fn(arg, param); } public static Func Curry(this Func fn, TCurried arg) { return […]
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 $$v_0, …, v_n$$, then a sum table is a corresponding list $$s_0, …, s_n$$ such that $$s_i=\sum\limits_{j=0}^i v_j$$. That is, each […]
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. […]
