Instant Star Rating

Released earlier this week was my star rating tool. I’d actually started this about a year ago but only remembered last weekend that I had it gathering dust in my hard drive.

Instant Star Rating allows you to create 5 star ratings in several different styles to go on your website. Unlike other star raters it doesn’t use Ajax. This is because Ajax doesn’t work across domains. Instead it uses the dynamic script method. When the user clicks on a star it loads a new script from the server. Read the rest of this entry »

Exploring Fractals

Fractals are some of the most intriguing shapes. The Mandelbrot set is one of the most intriguing fractal sets. To be honest with you I don’t really get what it represents and why it has such a weird shape but I know that it is intriguing to see.

For those mathematical boffins the Mandelbrot set can be defined as the set of complex values of c for which the orbit of 0 under iteration of the complex quadratic polynomial zn+1 = zn2 + c remains bounded. That is, a complex number, c, is in the Mandelbrot set if, when starting with z0=0 and applying the iteration repeatedly, the absolute value of zn never exceeds a certain number (that number depends on c) however large n gets.

Anaglyphs Types

Having recently added the anaglyph creator to my main website I decided to add some more options. Up till now I have offered bog standard colour anaglyphs. There are in fact several different ways of generating anaglyphs to get an optimal 3D image. For a full comparison see this article. The different types of anaglyphs are:

True: This but only displays the red and blue channels and doesn’t preserve any colour. The advantages are no ghosting but it does result in a dark image.

Greyscale: This creates a lighter image than the true anaglyph but results in more ghosting. Again no colour is preserved.

Colour: This preserves most of the colour but causes retinal rivalry. This is the type of anaglyph which I originally offered.

Half Colour: This preserves less of the colour but reduces the retinal rivalry.

Optimised: This uses none of the red channel from the original image so preserves none of the red colours but most of the blue and green. The advantages are almost no retinal rivalry.

I now believe that my anaglyph creator is the most comprehensive anaglyph creator available on the web. Please try it out with your own images and compare the different anaglyph types.

Instant Solve Updates

It’s the new year and I haven’t posted on my blog or made any modifications to my website for a long time. I’ve got around to making a few changes to my main site Instant Solve.

I’ve updated Instant Solve with two new tools. The first is the anaglyph creator which I created a while ago. Please try it out. Some fabulous images have been made with the anaglyph creator.

The second is a translation tool. It relies on the Google languages API. The translation tool is as good as Google translate but offers real time Ajax translation of text. Other features may also be added at a later date. If you do have any ideas or feedback, please leave a comment.

A few more tools are in the pipeline such as a maths tool which can help with solving equations, trigonometry, integration and differentiation. Unfortunately, this tool is proving more difficult than I first thought. Other projects are a kakuro and a griddler solver however since both problems are NP complete the solutions take a large amount of computing power. I have also yet to come up with a meaningful interface which doesn’t heavily rely on javascript.

Instant Quiz beta release

I have been working on this project for a few months so I am very happy to announce that Instant Quiz is live. Instant Quiz is an application which creates quizzes for you to share with friends, colleagues or students. Please sign up and try out the application. I would much appreciate any feedback or criticism to help improve the site.

Instant Quiz is still work in progress so some features haven’t been implemented yet. Quizzes don’t show answers and the quiz UI may change. In the next few weeks I am going to try and hook Instant Quiz up with Facebook so Facebook users can create quizzes for their friends to take.
