Posts in clojure

If you're a programmer, you're probably fairly comfortable with understanding and interpreting diff patches of the kind that git and other version control systems use. In this post we'll walk through a Clojure implementation of the Myers' diff algorithm, which is the algorithm used by Git.

Last week I started playing around with the Instaparse library, which makes writing parsers really easy in Clojure. What Instaparse does is take the formal definition of a language and give you a parser for that language. You can then use that parser on a string, possibly containing something in that language. You need to write the gra...

One of the classical problems in Natural Language Processing is parts-of-speech tagging i.e. given a sentence of length n, find the sequence of part-of-speech tags for each word in the sentence. For example,

p I recently found myself having to play around with some stock exchange data. The stock exchange in Nepal, unsurprisingly, doesn't provide a data API so I had to scrape their website. The non-realtime data isn't very interesting, just regular old scraping made a little more tedious by the fact that whoever designed the website didn't ...

In my previous post, I gave a pretty quick introduction to Clojurescript. If you haven't already, I recommend you read through that post. This post assumes that you have some Clojure knowledge and already have Leiningen running.

There doesn't seem to be much written about running Clojurescript, especially considering how great a tool it really is. I know there is a book that's coming out soon, but I had some trouble getting started with Clojurescript so I decided to put together this post, that hopefully at least some of you will find useful. This post does as...
