Retro gaming and an annoying mobile game

Thursday, February 2nd, 2006

Good news for all who like Commodore 64 games and bad news for office productivity: At c64s.com – classic Commodore 64 games online you can play all the classics you played instead of doing homework in your browser (as Java objects).

As I finally arrived in 2005 when it comes to mobiles (my girlfriend dropping my old one being the main initiator) I found a game for Nokia Smartphones that looks like nothing but is highly addictive and has that “Tetris” simplicity: Roto is a free J2ME game, and asks of you to put all the corners of a floating object on rectangles of the same colour to make the rectangles disappear. Sounds easy, and the first few levels seem ridiculous, but the game shows its teeth later on. You cannot turn the object, you can only accelerate and move it in 4 directions and bounce it off the edges of the screen. It is a fullfy fledged physics simulation and behaves accordingly. Good time waster for a while.

Internet Explorer 7 beta out

Wednesday, February 1st, 2006

Microsoft (no, I will not link this one) have shipped a beta of Internet Explorer 7 . It looks quite funky and requires XP SP2 to run. The catch is that it actually replaces your old MSIE6 (hey we all want that), which can be a real issue for testing. You can install the MSIE6 standalone alongside, but allegedly this might cause problems.

Therefore it might be best to install the MSIE 7 standalone version instead.

As for taking the new shiny MSIE for a ride, there is a test case collection going on at the CSS discuss wiki.

Seven accessibility mistakes part 1

Wednesday, February 1st, 2006

Digital Web just released the first part of a new two part article of mine entitled Seven Accessibility Mistakes .
In it I am listing mistakes I have encountered in the past (and done some of them) and give tips how to avoid them in the future.

Some of these tips might be utopic for you to achieve, but I for one am up for the challenge.

Form data preview with DOM

Monday, January 30th, 2006

I got asked to set this up as a proof of concept for an upcoming project, and it might be helpful to you guys, too:

Previewing collated form data with DOMscripting

The code is a bit wooly at the moment and I will clean it up and explain a bit more if I get the time.
In the meantime, just give it a swirl.

Google code analysis and another nifty Firefox extension

Thursday, January 26th, 2006

Google have released some statistics on web pages they have analysed:

In December 2005 we did an analysis of a sample of slightly over a billion documents, extracting information about popular class names, elements, attributes, and related metadata. The results we found are available below. We hope this is of use!

I would very much say so, so have a read about Google code webstats

Another Firefox extension I hadn’t known of earlier is Firebug which put together the best of JS console and the DOM inspector and even shows you your XMLhttpRequest data!
