I just published the simple-random ruby gem, which is ported from C# code by John D. Cook. You can view the source on github or install the gem via rubygems: gem install simple-random The gem allows you to sample from the following distributions: Beta Cauchy Chi Square Exponential Gamma Inverse Gamma Laplace (double exponential) Normal Student [...]

Java maps and sorting
Posted: 1 August 2009 in UncategorizedTags: algorithms, code, collections, java, programming, sorting
I’m always a little annoyed I have to implement sorting Map keys by their values myself in Java. It seems like they should be a part of the standard Collections library or something. Maybe they are and I just haven’t seen it? My solution (gist) is based on feedback from Josh in the comments to [...]
Jekyll and Code

Tom Preston-Werner, aka mojombo, rocks. When GitHub announced GitHub Pages recently, they pointed to a new blog engine, Jekyll. Jekyll generates the blog as a set of static pages — no database reads, no PHP, just fast HTML. I was instantly drawn to it, and since I’ve been itching to switch blog engines, I damn [...]
LDA in Ruby

Since Ruby is my new favorite toy, I thought it would be fun to try my hand at C extensions. I came across David Blei’s C code for Latent Dirichlet Allocation and it looked simple enough to convert into a Ruby module. Ruby makes it very easy to wrap some C functions (which is good [...]
Plurk your tweets

A couple of days ago, I wrote a script that would tweet anything you plurked. Thanks to some code from Neville Newey (based on PHP code by Charl van Niekerk), the plurk.py script I wrote has been updated to both plurk your tweets and tweet your plurks. This should work on both windows and linux [...]
Tweet your plurks

If you want to use Plurk, but aren’t ready to leave Twitter, I wrote a little python script you can use to automatically mirror your plurks on Twitter. This will not work for response plurks, but your main plurks will be extracted and posted to your Twitter account with the prefix “plurking:” followed by your [...]
Java Properties

I discovered the java.util.Properties class a couple weeks ago in the ginormous Java API docs. If you’ve ever created a software project where you have a lot of different settings that change frequently, this is the class for you. In my research, I implement all these different algorithms for various things, find out they don’t [...]
brainfscking set theory
Posted: 3 December 2007 in UncategorizedTags: arithmetic, brainfuck, code, computer science, math, mathematics, set theory
I mentioned the esoteric programming language brainfuck a little while back. It consists of 8 operations and was created in order to make the smallest compiler in the world (I think the current best is 174 bytes). I was reading a post over on Good Math, Bad Math that defines arithmetic in terms of sets. [...]

Either the coolest or the stupidest programming language in the world, brainfuck was designed by Urban Müller in order to create the world’s smallest compiler of a Turing-complete programming language. Originally his compiler was 240 bytes in size, but he reportedly got it down to about 200 bytes. Others have gotten it below that. The [...]

Ever get pissed twice before you’ve really even opened your eyes? This is why I shouldn’t read my RSS feeds so early in the morning. At the top of the list is Bush equating Democrats who oppose the war (as if it could be called opposition, anyway) to those who ignored Hitler and Lenin and [...]
