A Javascript library to manipulate vector and matrices.

Homage to the computer that set my imagination wild. This really brought back memories.

Pure python barebones pgsql adapter. Ultra cool.

A long thread of discussion covering the PEP 333 and the decoding of the PATH_INFO attribute in the environ dict. Final verdict – its sucks, but it should be decoded. Reason being the CGI spec, which the PEP 333 refers to says so. I encountered this issue when I noticed that wsgi-inspect does not actually decode the PATH_INFO attribute.

A useful tool when you need a simple tool to code and decode strings quickly.

A great collection of notes on how to hack TiddlyWiki. TiddlyWiki is one of those excellent examples of a completely javascript based web application, with the potential of working in a distributed, semi connected environment. With things like Gears and TiddlyWiki one can imagine web based application that work offline, and sync online seemlessly. Something to bite into soon.

"I think it’s because institutions are so good at squeezing the fun out of everything. It’s appalling for example how schools can take the most vibrant topics and mangle them into formulaic, mediocre slog. And so it is for programming. Many corporations turn an inherently rewarding experience into something people just barely stomach in exchange for a paycheck." Amen brother.

Standards and techniques to look into if we are ever going to implement a simple json interface ontop of arbitiary databases – ala DBslayer

A proposal that sets forward a schema and a refernce implementation of a validator. Is this just complicating a simple serialization format ?

A windows ME app that can read barcodes. Based on zxing. I need to try this out !

Java based (JavaME and Android support ) library to read barcodes. Looks interesting – no support for Windows ME though.

How to read a barcode from a black and white image of a barcode. Now will need to figure out code that will be able to detect a barcode in an image. Promising nonetheless

A barcode reading utility. Based on the code from http://www.wiredfool.com/2006/07/04/barcode-recognition/. Pass it an image and it reads the barcode.

Note to self – When encoountering the "Argument list too long" because the bash expansion choked on a large list of files – use "find ./ -name '<pattern_to_match>' | xargs <cmd_to_run>"

A very cool tutorial on using Raphaël to make a performance monitoring graph. Very clean code and nice looks.

Python – pass by value or pass by reference ? Neither it seems . Great summary.

An interesting ongoing tutorial on implementing the MVS stack within the browser (A-la JavascriptMVC.com). Looks intriguing and possiby a solution to the mess large javascript applications tend to be. However, the jury is still out (IMHO) as to the whether a MVC framework within the browser is really the best solution for this

An excellent tool that makes use of modest maps to build a topogrpahical visualisation of web visitors.

Pythons 'with' statement. Setup and cleanup cold handled elegantly. effbot.org is excellent.

Gedit is slowly growing on me. Maybe you really don't need a VM to run your IDE This is a simple recipe to add XMLIndenting. Useful indeed.
