In this second part we look at the factory methods to handle the different request and the formatters classes.

A REST API in 20 minutes - Part 1.

If you haven't look at it, take a look at the Subsonic project, is really cool and can generate a ORM infrastructure faster than any other framework I tried out there. It also provides a cool HTTPHandler to expose those objects.

Why you need to use a good architecture when writing JavaScript

I'm working in an application originally programmed in 200 by only one developer. I really clever guy that put in place quiet a bit of base code. The original design of the application is not all that bad, but several waves of developers have done maintenance on it.

Adam Goucher gave a good presentation on the use of Selenium for web automation. These are my notes taken during the session.

Luca, a quick look at the request object.

I decided to completely isolate Luca from the HttpRequest object and define my own. The main advantage of this approach is that having a pure javascript object, mocking and stubbing is extremely easy, making testing a breeze.

Luca, writing a simple web service.

As a first simple example of using Luca I wanted to write a simple web service that returns json or plain text.

Creating my first WP7 application.

I decided that my first Windows Phone 7 application should be a Pomodoro timer. It's a fairly simple thing to do and useful at the same time.

Luca, abstracting the request object.

The JavaScript engine allows for the use of .Net objects inside JavaScript, but I wanted to completelly abstract Luca from anything related to the HttpContext.

Luca - server side JavaScript websites in .Net, choosing the engine.

I wanted a very simple framework more like Sinatra than Rails. Something that make very easy to put together some simple Restful websites. And I wanted to use JavaScript to write my code and be able to run it inside .Net and IIS. But first I needed to find my JavaScript engine.

A list of books for my team.

Today I started to put together a list of books that I will like my team to read. The list started to grow so I have to do some triage. Here is the result.

Last Saturday I had the opportunity to assist the first WindyCityDb. A one day, single track conference on databases technologies that are usually grouped under the NoSql umbrella. In general the conference was very good.

Pickle cucumber steps not recognized before creating the model.

The title kind of tell it all. I started to use pickle now for filling up and managing my test with cucumber. Fill up data, etc. Pickle creates some step definitions for you to make things easy, what it's much appreciated.

Node.js web development with Express

I have been researching node.js and the ecosystem around it. Yes, node has an ecosystem, a very vibrant one if I may say. Today I tried a simple web framework that resembles Ruby's Sinatra by the name of Express.

If you, like me, haven't been able to go to PyCon don't despair. The videos of the sessions are available at blip.tv.

Mercurial integration with Visual Studio

I recently posted about how to integrate Git with Visual Studio. Of course Git is not the only DVCS out there. Mercurial is another source control system similar to Git that is having more and more relevance.

Git integration with Visual Studio

I started to use Git seriously 5 months ago when I sign up for my Github account on September 1st 2009. Before that I was a very happy subversion user. One of the things that I really like about Git is the speed.

Using SpecFlow + WatiN or BDD for web applications without leaving the CLR.

Last week I wrote about using cucumber to test your web applications outside in. In the post I showed a simple example (actually comes with cucumber) to open a browser, go to a site and perform some actions.

Test driven outside in, starting with Cucumber and RubyMine.

On my new project I want to start using end to end testing. The idea is to write an specification run it against an outer interface. Gui, Web service, etc. It fails. So you start implementing the feature using TDD until the Spec pass.

Ruby Koans, learning ruby the test driven way.

Probably you are aware of Edgecase Ruby Koans. In case you aren't, let me introduce you to them.

The simplicity and speed of Git and DVCS in general.

Since I started using Git a few months ago, and particularly GitHub since last September, my life have been good in DVCS land.I used to be a Subversion user and I was happy*, maybe because I didn't know anything better.

Insert route, route registration after the fact on ASP.NET MVC

Kazi Manzur Rashid has a post about registering Areas dynamically after the registration of other routes and the problems this has since the order the routes are registered is very important.

My new an improved tooling for builds and project management.

I try to be pragmatic in my approach to development and one of the things that change the most are the tools I use to deliver software. There are several reasons why I change tools so often.

Using the Connection String section for Log4Net and NHibernate

The other day at the office my boss took a look at our configuration files and he expressed his concern about breaking DRY with all the ConnectionStrings. One for Ado.Net, one for NHibernate, one for our caching db and another for Log4Net.

Proper naming in generics and Lambda expressions.

Hopefully gone are the days were you considered ok the use of single letter names for your variables or your arguments and you are giving informative names to all the artifacts in your code.

Using Gestalt in a site that already uses prototype.js

Gestalt, the new js library release by the MIX Online labs, takes a dependency on jQuery. They use it to do some Dom manipulation (locate tags, modify the Dom). But what happens if you already use prototype.js in your application?

Yellow sticky notes for your watched variables in the new VS 2010.

One new feature in the code editor is the ability to put sticky notes in the code while debugging. This sticky notes are actually attached to a given variable and you can see the actual value of it in the note (similar to using the watch window).

Common List E-book (free online) Apparently you can also download it from the Apress website's book page but the link was down for maintenance when I tried.

Extending ASP.NET MVC

I want to be positive in this post. So I will just mention this once. The framework is very extensible but It's more difficult that It should. I guess that the problem is not really with the framework, but me trying to make it do something that is not in the spirit of it.

Silent lately

I have been silent lately because I have been working on a project based on ASP.NET MVC. The idea is to have the bare minimum to create highly configurable sites.

Why testing saves time.

Exploring why the detractors of TDD that seen it as a waste of time are just plain wrong.

ASP.NET MVC in Action chapters 5,6 and 7.

I enjoyed this chapters as well, specially chapter 6 and 7 about extending the framework and preparing your site so it scale. Some of the code examples are using a previous (old) version of the framework. I hope they will be updated for the print version.

You can only refactor when you have a testing suite.

I don't remember if I read this on Clean Code or Refactoring or maybe I just hear it somewhere, but It's so true. It's not that you can't change the code and that you can't apply refactoring techniques.

Auto properties in c#, what the compiler does for you.

If you ever wonder what the compiler does to make the auto properties work let's take a look at the code the way Reflector sees it.
