James Brown's Celebrity Hot Tub Party!

This site has the low down on James Brown's Hot Tub Party. If you have no idea what I mean, take the time to enjoy the (19MB!) video.

Soon you will not be able to hear "Hot Tub" without shouting "Good God!".

Camera Phone Enabled Home Screen | Virtuoffice

PhotoPlug is a neat little application that makes the camera the centre of your smartphone's world. It's in beta at the moment, but you will get the point.

Feed me better

Feed me better is an online campaign that accompanies Jamie's School Dinners - an great show that highlighted the national disgrace of British school dinners.

There is an online petition that closes on Easter Monday, and I hope you will join me in signing it. In the short time Jamie's regime was in force at the test schools, the kids became better behaved, more attentative, and asthma rates fell dramatically!

Drawing Fractals With Interval Arithmetic - Part 1

Interval arithmetic is a radical programming paradigm that allows you to write provably rigorous algorithms, which I have blogged about before.

I have written a paper about the application of interval arithmetic to the problem of fractal rendering (if one can call it a "problem"). The paper is available here:

Drawing Fractals With Interval Arithmetic - Part 1

The paper includes a fractal-explorer tool for reproducing the results, a sample of which can be seen here:

  

The graphic on the left is a Mandelbrot drawn with the traditional single-point approach, and the one on the right is the result of the interval approach.

Like fractals, many (if not all) chaotic systems are iterative, and this paper has implications for simulating chaotic systems regardless of whether one uses interval or single-point methods.

In Part 2 I will try and quantify the results I am seeing, and investigate more sophisticated implementations of the maths behind the Mandelbrot equation.

Keima

Keima is a new website I have set up as a place to put interesting software. It will also be a place to put technical content that is too-big-to-blog.

The first things to go up will be a couple of small .NET libaries that I have been fiddling with recently. The intention is for all content to be original.

I am still playing with the mission statement and the general presentation of the information, so I would welcome (constructive) comments.

Cardiff boy lands plum job...

BBC NEWS | Business | Sony appoints first foreign head

Amazingly Sony are replacing their long serving CEO Nobuyuki with UK-born Sir Howard Stringer.

Sony once turned me down for being colour blind, so I am slightly peeved that Howard doesn't even speak Japanese.

Freeware Smartphone Boardgames

There are plenty of Chess games available for the smartphone, but Valentin Iliescu Chess is free.

Pocket GNU Go is unlikely to challenge real players of the game, but it should be able to give me a run for my money.

LeonardRossiter.com: Reggie Online

Reggie is one of my all time favourite fictional characters (followed closely by C.J.), and I love this website dedicated to all things Perrin.

I'm quite tempted to buy the complete collection boxset - £28 for all three series is great value.

Update: Simon points out that it's cheaper on Play - even more of a bargin!
