QuadDioph is a new piece of software from Martin Carradus. It’s an application that solves or finds “solution of certain Quadratic Diophantine Equations, of the form x^2 + B.x.y + A.y^2 = z^p, (e.g. x^2 + y^2 = z^2, two squares adding to a square, or x^2 + y^2 = z^3, two squares adding to a cube).” The application is free to download from Martin’s website.

There are two pieces of news from R-Comp, with the first being the release of version 6.03 of Messenger Pro, which has already been sent out to users. According to Andrew Rawnsley, the new version provides better compatibility with all RISC OS machines, and makes it much simpler to switch users “on the fly”, thanks to new toolbar buttons. Printing has also been tweaked. Andrew asks that if you’re an existing user who hasn’t received the update for whatever reason, please contact R-Comp to receive the update, which is free to anyone owning v6.
R-Comp’s second piece of news is that an operating system upgrade for ARMini users has been released to existing users. The update has been made as simple as possible, with a friendly desktop application that explains the process and lists the changes and new features, and an “Update now” button to actually install the new version of RISC OS, keeping things as simple and painless as possible for users. Once installed, there’s also an easy to use procedure “roll back” to older versions should the need arise. Features of this new version of the operating system include a smoother desktop experience, with particular improvements to dragging windows, etc, enhanced USB device support, improved handling of removable storage devices on the front USB ports, better performance from the built-in card reader also performs better, and the new “filer action” window recently discussed on the RISC OS Open Ltd forum, with a percentage completed bar during copy/delete operations. The update also resolves some minor issues with some of David Pilling’s applications.
Most RISC OS users will probably be aware of Xara, who were once known as Computer Concepts and developed software like Impression and ArtWorks, amongst other things, for RISC OS computers.
