## Fractional Derivatives and Integrals

You may recall that one of the first things we learn in calculus is simple derivatives, $$\frac{d}{dx} (x^2) = 2x.$$ We quickly learn a pattern forms. The general method for differentiating a monomial is $$\frac{d}{dx} (x^k) = kx^{k-1}.$$ Of course, if we differentiate once, we can do it again. These...

## Crafting Tweaks with a Jailbroken iPhone: Part 2 - Theos, Logos and Hooking

Last time, we used Cycript to do a little memory tweaking and change the "No Notifications" sign to something a little different. To do this we found the object that controlled the "No Notifications" sign, in this case a UILabel, and ran the setText method on it. [nnLabel setText:@"S'all Good"]...

## Crafting Tweaks with a Jailbroken iPhone: Part 1 - Cycript

Do you own an iPhone or an iPad? If so have you ever considered jailbreaking it? Probably not, as according to CodeProof only about 10% of devices are jailbroken. This is partly because jailbreaking has a bit of an image problem - seen as a set of instructions that one...

## New Paper Published

We've had a new paper published in Journal of Physics: Conference Series. It's open access, so you can read it here!

## A 3D Engine

I've been working on a 3D engine. This isn't the first time I've had a go at this, although the previous time it was written in Java - a language I did not have much experience with at the time - and used the LWJGL which did most of the...
