I can drive a car!

I passed my driving test! From now on, I can get everywhere much easier and faster than by cycle. Next Thursday my driving license will be ready to be picked up at the municipality house, so I have to wait a week.

The driving test wasn’t bad at all, I didn’t need to drive throughout many difficult area’s, so that was lucky for me. One time I was a little bit confused, but I could organize it well enough.

I can’t wait until next week… :)

Solving a Sudoku puzzle with JavaScript

Although I build this many months ago when I got bored, I didn’t publish the Sudoku Solver. I was just interested in how fast JavaScript could do this, and if I had the skills to code all the logical things.

The solver doesn’t solve very hard Sudokus, but many puzzles you’ll find in newspapers he solves in just a second or two. If you have some tips on how to solve this faster, or better, please leave a comment here.

Also mention this is not a best practice project, the JavaScript is not optimal and is embedded in the HTML document instead of doing this unobtrusive.

During the building of the solver, I also found another Sudoku Solver with even more solving methods and some great options. I also found a Sudoku Programmers Forum, but the more of the things discussed there I didn’t understand.

Launching my Codex

Finally I had some time to build my codex, my publishing platform for scripts, code and articles. At this moment there is only one live script (I’ll blog about this very soon), but some more are on the way!
For some extra usability I added some JavaScript to make it much more prettier to read, although this effect is nicer to see with more items than only one. I’ve done the scripting with jQuery, and this is actually the first time that I used that library. JQuery works fine for me and I think I’ll use it in more projects.

Thanks to Kilian for some tips and help building it.

World’s Highest Website…

I translated World’s Highest Website into Dutch. WHWS is a CSS experiment to see how high browsers a web page can render, currently the site is almost 19 kilometers high. The website is an idea of Jens Meiert, a front-end developer from Germany.

Review: Don’t Make Me Think!

A Common Sense Approach to Web Usability

That’s what the cover says about Steve Krugs Don’t Make Me Think!. I bought myself a copy of this book, since I got interested by various other web designers who own this book as well.

The first chapter directly explains the title of the book, it is the first law of Krug: ‘Don’t Make Me Think!’. Leading is the task to get rid of all questions users of a web site can have when they visit it, like ‘What’s this?’ and ‘Can I click on that?’.

The other chapters are written in the same clear way as the first chapter: to the point. Krug did a good one on that: he explains most of the content with good examples.

The diversity of the content is also nice: chapter five is about text writing, and chapter three explains how to design web pages for scanning. In the same way chapter seven tells how to design a good homepage, and nine how to test with users.

I’m happy that I’ve bought it.
