More and more smartphone manufacturers have been moving towards on-screen buttons, with Google really pushing for it over the physical button alternative. However, there are still a few OEMs (we're looking at you, Samsung) that have preferred to keep things a bit more traditional. Tell us which way you prefer and why.
Complex Numbers App Makes the Imaginary Seem More Tangible
It’s not quite back-to-school time anymore, and not many people deal with complex numbers on a day to day basis. But if you’re a student or engineer, it never hurts to incorporate a new tool to streamline your tasks.
XDA Forum Member WeissenbornC recently created an app to help you work with complex numbers more easily. The app is divided up into four pages: basic arithmetic, quadratic equation, roots, and polynomial factorization.
Basic Arithmetic allows you to perform simple operations on complex numbers such as adding or multiplying them, taking their root, or performing trigonometric functions. Quadratic Equation allows you to use real and complex coefficients to solve using the quadratic equation. Roots allows you to solve n-degree polynomials for all of the roots using the Durand Kerner Method. Finally, Polynomial Factorization takes an n-degree polynomial and divides it into n factors.
If you’re a student or engineer constantly working with complex numbers or if you simply want a tool to help you with quadratic factorization, Complex Numbers can potentially be a huge time saver. Head over to the application thread to give Complex Numbers a shot!

While there are frequent unexplained changes and pushes to Google's AOSP repositories, an interesting-looking new branch has been pushed out recently, called "master-soong". Taking a look at the changes made to the manifest repository (which is used to specify the repositories to be downloaded when building Android), it appears there are some new repositories making an appearance. Of note here are new prebuilt repositories for Go, and Ninja. Go is a programming language, created by Google, which compiles to produce...
There already are many solutions on the Google Play store if you want to send a link to one of your devices -- but what if you wanted to do it quickly without having to install any software or logging in to a website on the recipient end? Most apps require you to do either or both, which can be a hassle (or even a security risk) in some cases. Luckily, XDA Forum Member wyemun has developed CaastMe. Inspired by...
