JS1k Winners – Top Ten Entries

So, the JS1k contest is over and the winners are finally in! What a fantastic event this has been, massive thanks to all the organisers and judges, and to all the entrants for putting on a great show, I can’t think of a single entry I wouldn’t have been proud to have written myself, and some of the entries were simply amazing.

The judges did a brilliant (and difficult!) job of ranking the entries and choosing their top ten. I’ve compiled the entries into a list below, and you can click through to the demos themselves from here. I read on twitter that the official site will be updated tonight, so check back at for the full scoop :)

If this is the first you’ve heard of the contest, head over to and browse through all the entries. I also compiled a list of all the tweet-sized entries, as I’m buying a copy of Douglas Crockford’s JavaScript:The Good Parts as a prize for the best tweetable entry. Have a look at my own tweetable entries too.

js1k: an allRGB entry in <1k of JavaScript

It’s contest season! The An Event Apart 10k JavaScript app contest has just ended (my entry got 2/5), there’s a node.js contest, and the JS1k contest is ending on Sept 10th. JS1k is a much purer contest, disallowing any external libraries, while the 10k contest allowed things like jQuery and external web services. As Frederick Polgardy puts it, js1k is “An exercise in constraint, resulting in a kind of executable haiku”.

For js1k, I’ve entered a port of my PHP allRGB entry. The allRGB project is a great idea in itself – create an image which contains every possible colour in the RGB space exactly once. That’s 256*256*256 colours (=16777216), in a 4096×4096 image. Quite a challenge for PHP, and certainly not the kind of thing you’d attempt in JavaScript, right? ;D

allRGB Entry – PHP Image Manipulation

The objective of allRGB is simple: To create images with one pixel for every rgb-color (16777216 to be exact); not one color missing, and not one color twice.

What a cool project! As regular readers will know, I love messing about with image manipulation in PHP, so when I heard about the allRGB project I knew I had to make an entry for it. A few false starts and about half an hour later, I proudly submitted my first entry, a 4096×4096 PNG image containing every single possible RGB colour. As one redditor put it, “It’s like poetry, just without words.”

Adaptive Web Sites

(this is a slightly expanded transcript of a talk I gave at Oxford in June 2009 about my work there)

Hi! I’m Howard Yeend, my supervisor is Vasile Palade, and the title of my project is:

Implementing Adaptive Web Sites using Machine Learning and Ajax“.

But before I talk about what all those buzzwords mean, I’d like to give a little background information about why this is an important research area, and why I feel it’s the right project for me.

When I was trying to think of a project title, I had a question in mind:

How can we improve the web?

And I think that’s a hugely important question for us to ask.

3D PHP – playing with ImageCreate

A PHP city (it gets better after the break):

PHP ImageCreate

Basically I was bored one day and decided to play around with ImageCreate and ended up making this “crate” demo (click the image for some other experiments).

And then everything got a bit silly and I made this:

Neat Windows Tools

Most of these tools have a computer security slant, some cannot be classified under any other term than ‘hacking tools’, so be careful when running them, especially if you don’t know what they do. Tools that interact with a network in a potentially dangerous way are marked with ‘D’. Read the rest of this entry »

The Right To Read

Taken from

For Dan Halbert, the road to Tycho began in college–when Lissa Lenz asked to borrow his computer. Hers had broken down, and unless she could borrow another, she would fail her midterm project. There was no one she dared ask, except Dan.

Go placidly amid the spam and waste,
and remember what peace there may be in a decent firewall.
As far as possible without surrender
never run untrusted executables.
Post your comments quickly but clearly;
and read the others,
EVEN THE ONES IN CAPS, and the ignorant;
we too were noobs once

The Hacker’s Manifesto

The Conscience of a Hacker
better known as “The Hacker’s Manifesto”.
A prolific and influential piece of writing, January 8, 1986:

Another one got caught today, it’s all over the papers. “Teenager Arrested in Computer Crime Scandal”, “Hacker Arrested after Bank Tampering”…

Damn kids.
They’re all alike.
