[update: First, my apologies to jdalton, my post was not meant to derail Fusebox, merely to show a different approach to similar problems. ] I read a post on Ajaxian about Fusebox, a JavaScript library which is described as: [...] The problem is that frameworks / libraries / third-party scripts may overwrite ...

The Joy of Clojure

Thursday, January 14th, 2010

In case you haven't noticed there is a very interesting Clojure book coming out, titled "The Joy of Clojure," written by two very interesting authors that anyone hanging out in the Clojure community should know: Chris Houser and Michael Fogus. As an appetizer, the first chapter is available for ...

Please help funding Clojure

Tuesday, December 15th, 2009

Rich Hickey, creator of Clojure: As should be obvious, Clojure is a labor of love on my part. Started as a self-funded sabbatical project, Clojure has come to occupy me far more than full-time. However, Clojure does not have institutional or corporate sponsorship, and was not, and is not, the by-product of another ...

Review: Ext JS 3.0 Cookbook

Wednesday, December 9th, 2009

Intro and motivation. While my recent blogging activity and interests have been (and are) about Clojure, I am still very much interested in, and actively programming, JavaScript. That is why I immediately accepted when Amit Sharma from Packt Publishing asked me to review the new book Ext JS 3.0 cookbook ...

Clojure circuit breaker

Monday, November 23rd, 2009

[Update Jan 1., 2010: A couple of people have been linking and twitting this, so I've made the blog entry match the current Clojure version at github. Code works in the 'new' branch of Clojure: tested with commit 3ae9e8874d43f9fd37e59bb7ea8cce0f85bac101. There is support for creating several circuit breakers wrapping given functions]. As an ...

Identity, State and Values

Please watch this video carefully at least once: http://www.infoq.com/presentations/Value-Identity-State-Rich-Hickey It is pretty hard not to agree, isn't it... Give in now.

Monty hall and Bayesian probability theory

Tuesday, June 23rd, 2009

Jeff Atwood discusses the "Monty hall" problem. I made a comment about why I believe people's intuition is often wrong when presented with the problem: I believe it is due to the way probability theory is taught in schools and universities. The notion of probability simply as an extension of ...

Clojure event sourcing

Sunday, February 22nd, 2009

Event sourcing: Event Sourcing ensures that all changes to application state are stored as a sequence of events. Not just can we query these events, we can also use the event log to reconstruct past states, and as a foundation to automatically adjust the state to cope with retroactive changes. I recently ...

Happy New Year!

Wednesday, December 31st, 2008

Can't remember the last time I laughed so much. http://www.yankeepotroast.org/archives/2008/09/11_words_that_s.html Got the Link from Ryan Tomayko's (great) blog.

IE doesn’t understand HTML or HTTP

Saturday, December 20th, 2008

The so-called "web"-browser Internet Explorer version 7 (and probably all versions below) doesn't get HTML or HTTP. In a recent project for a client we've been building an advanced, 100% JavaScript client application that had to run in IE7 (as a minimal requirement). The application is rather complex and has ...
