Finally an update!

It’s been over a year since I last wrote on this blog. I’ve updated to the latest version of wordpress and changed themes.
I’m hoping to have enough time to take an active interest in my blog, but life has been so busy as my wife just moved here.

I’ve been programming often in Java and Ruby lately, so that is good. Hopefully I’ll have some code to put up in a repository in the near future.

I’ve been working on a framework in Java for testing trading ideas. I’ve been testing it with a simple grid system.

The grid functions based on the current Net-asset Value, and will close all trades after a specified profit level is reached. As I develop a better framework I’ll write more about it.

Google App Engine

It was great news to hear how google has adopted java servlets as the second platform for app engine. My account has it enable now and I look forward to tesing it out.

The few restrictions that exist do not really seem to matter. I haven’t seen a situation where it’d be ideal for a servlet to spawn a thread, though I’m sure someone could point out such a situation.

Later I’ll write more about my experiences with it.

jQuery and IE

I’ve had an interest in testing out jQuery for some time now and this weekend I finally dived right in with a simple ajax example quiz service. The backend was quickly designed as a servlet outputing JSON, leaving me with the frontend to do in jQuery.

As I did the initial design in firefox everything went smoothly, until I tested in IE. The kanji (word) to quiz wouldn’t update on the page. A quick google later I learned IE often will cache the get request. The simple fix was to include the current time as the data in the get, and after that IE stopped caching the requests.

For now the site is very simple as I do not plan to update it, but I will use spring mvc to build the next version.

Java Spring

I’ve started working with Spring, and to me the Inversion of Control via Dependency Injection really stands out as a nice design methodology. Of course this is a concept one can use in any software when required, even without Spring.

After reading about the foundation of Spring, I cannot wait to use it. I plan to discuss it more sufficiently as I gain more experience with it. I’d like to test out its web MVC module as soon as possible.
