Great blog for Java Design Patterns

I came across this great site via DZone. The site provides a great overview of the Gang of Four patterns as well as J2EE patterns with UML diagrams and sample code for each one. Here what the author, Andre Mare wants to get from the blog.

Java Design Concepts will provide information on how to design, implement and deploy system in a high availability enterprise environment. The design concepts include design patterns, and Object Oriented Programming (OO). Java technologies include J2EE, EJB, JAF, JMS, JSP, JSTL, JDBC etc..

As the site is still in development some of the J2EE patterns are not complete yet but this is definitely one for your RSS reader.

Check out the site here…
UPDATE
(Looks like the site is now down)

New Irish site for Vehicle Registration Tax

Vrt IrelandIn July of 2008 the Irish government intend to change the way it determines the amount of tax to pay to register a car in Ireland. The old model was based on the size of the engine while the new model will be based on the Co2 emissions from the car. The same model will be used to determine the amount of road tax to pay for new vehicles.
I was looking for information on Vehicle Registration Tax and found it hard to find a site that would let me compare the various cars in a band. There are sites out there where I can look for a particular model and see the emissions for that car but no site would compare ‘All cars in emission Band A’ .

I decide to create a site myself. Its very basic at the moment and provides tables for each car type as well as one very large table that contains all of the cars and allows the user to sort by band. I’m using the wp-Table plugin to build each of the tables on the site. This plugin uses a mysql table to store the various rows of each table. It also allows you to upload the data in CSV format which helped a lot.

Ever want to run your web application on Google’s infrastructure?

Well now you can….

Google just launched a preview of their app enigne. You can read all about it here.

With Google App Engine, developers can write web applications based on the same building blocks that Google uses, like GFS and Bigtable. Google App Engine packages those building blocks and provides access to scalable infrastructure that we hope will make it easier for developers to scale their applications automatically as they grow. This means they can spend less time dealing with system administration and maintenance, and more time building and improving their applications. (There’s more detail on the new App Engine Blog.)

I tried to sign up but it looks like the first 10,000 have already applied. You can still download the API from here in the mean time if you want.

Daylight robbery in M&S Ireland

At a time when the Euro is getting very close to the 80 pence mark, M&S in dublin are ripping people off with an exchange rate of 55 pence to the Euro.

See the example below, a packet of puff biscuits that retails for 99p sterling was being sold for 1.79 Euro in M&S in Dundrum.

Exchange rate rip off in M&S Dundrum

I can understand that not all shops are going to update their prices every week to keep in line with the current exchange rate but an exchange rate of 55 pence is disgraceful.
