I’ve been having a lot of fun learning Haskell these past few months, but getting started isn’t quite as straight-forward as it could be. I had the good fortune to work at the right place at the right time and was able to take Bryan O’Sullivan’s Haskell class at Facebook, but it’s definitely possible to get started on your own. While you can play a bit with Haskell at Try Haskell you’ll eventually

Mochi Media's Code Substantial multi-language codebase Erlang code going back to 2006 Did not always have good tests :( Doing It Wrong Write code without tests or review Push to production branch Deploy Firefight [and repeat] Doing It Better Write code, tests and docs Push to issue branch Review [and repeat] Merge to production branch Continuous Integration server runs tests (again) Deploy

Python 2.6 was released yesterday, which has tons of cool new features including a new json library and a new multiprocessing library. The json library is basically simplejson (from a few months ago) minus the Python 2.4/2.5 support and refactored to take advantage of the latest future-compatible features (such as the new str.format method instead of using % format interpolation). The only downsid

Aral Balkan has recently released SWX, a new data exchange format for Flash. In his current implementation it's really two standards: A JSON-ish format based on PHP (bad idea) and a particular layout of SWF bytecode on the receiving end (good idea). Creating another JSON-like format is stupid. I really don't know why he did that. There are plenty of fast parsers for JSON in PHP, which are almost c

While I didn't personally attend Freedel 06, I recently came across the slides for Anant Narayanan's Web Application Development talk. Specifically it covers JavaScript web application development with MochiKit and Dojo, and it's split into four sets of slides. I've just had a chance to give them a look and they're quite good. The slides are all done with S5, which is what I used for the MochiKit

In JavaScript, there are basically two kinds of object iteration: All objects support property enumeration: for (var propName in someObject) { var value = someObject[propName]; } Some objects support the "Array protocol": for (var i=0; i<someObject.length; i++) { var value = someObject[i]; } These both suck. Property enumeration is only really useful for debugging, since chances are the objects wi

Bob Ippolito (@etrepum) on Haskell, Python, Erlang, JavaScript, etc. I’m pleased to announce that OSTIF recently sponsored a security audit of simplejson, performed by X41 D-Sec. The release of simplejson v3.9.1 includes fixes for the potential security issues discovered in this audit, as well as a number of security hardening measures it recommended. Many open source projects such as simplejson a
