This page is a work in progress and more for my own benefit than anyone else.  It is an easy way for me to keep a list of certain online resources that I may not use a lot but which are just the thing when I do need them.

Open Web Application Security Project (OWASP)

Outstanding resource for how to write secure applications generally, and secure web applications in particular.

ThoughtWorks Technology Radar

ThoughtWorks is best known as a thought leader in the Agile movement through the writings and teachings of its Chief Scientist, Martin Fowler. Part of this leadership is its annual technology radar which is broken down into four areas, Techniques, Tools, Platforms and Languages and Frameworks. Within each, technologies are categorizes by what phase of adoption they are in, ranging from “hold” (don’t use), through “assess”, “trial” and “adopt.” Its definitely worth looking at.

JSON Pretty Print

Super simple, paste in any JSON and have it formatted nicely. Great for making any JSON that lacks white space readable.

Chrome Postman Plug-in

This is a great little tool for generating HTTP requests and examining the results—perfect for REST endpoint testing.

RegExr: Online Regular Expression Tester

This one is a flash application but its as full featured and interactive as any expression tester you could ever want.  It uses the ActionScript 3 regex engine so its not going to work perfectly for .Net.  If you need something .Net specific try Derek Slager’s online tester.

Awesome site for learning CoffeeScript and for converting your legacy javascript files to more maintainable coffee script. Converts both ways and can be used as an online editor for both, converting from one to the other on the fly as you type!


Got one of those pesky problems that is likely the result of malformed Javascript being interpreted not the way you intended by an overly forgiving interpreter?  JSLint will check it with merciless exactitude for you.

W3C XHTML Validator

What can I say, the best way to make sure your HTML is XHTML compliant.


From the site: “ is primarily a wiki, allowing developers to find, edit and add PInvoke signatures, user-defined types, and any other information related to calling Win32 and other unmanaged APIs from managed code.”

Graham King – Credit card numbers

Provides a list of randomly generated credit card numbers for all major card types that will pass the initial check-sum validation of most e-commerce sites. Immensely handy if you are testing out an e-commerce site or using the PayPal sandbox. The page also contain links to other useful information about credit card number and CVC algorithms, etc.


Simple little site to generate animated “loading” gifs (a.k.a. “spinners”) styled to match your website.
