If you get a mysterious USB stick in your mailbox, don't use it - obviously. USB sticks containing harmful malware have been left in Australian letterboxes, police in Victoria have warned. Residents of Pakenham, a suburb of Melbourne, have reportedly found the unmarked sticks in the boxes. Plugging them into a computer triggers fraudulent media-streaming service offers, as well as other malware, the force said in a statement. The devices are "extremely harmful" and should not be used, police say.

HP are also annoying people by stealthily blocking aftermarket ink cartridges in their printers. And consumer advocacy group Choice says it will begin investigating whether HP has breached Australian Consumer Law. Early last week, HP printer owners using non-HP ink cartridges began to complain they were receiving error messages such as "cartridge problem", "one or more cartridges are missing or damaged" or "older generation cartridge".

NZ researchers have restored the first recordings of computer-generated music, credited to Alan Turing. The aural artefact, which paved the way for everything from synthesisers to modern electronica, opens with a staunchly conservative tune — the British national anthem God Save the King. Researchers at the University of Canterbury (UC) in Christchurch said it showed Turing — best known as the father of computing who broke the WWII Enigma code — was also a musical innovator.

ARM have a new safety processor aimed at (among other things) the autonomous car market. James McNiven, general manager for CPU and media processing groups at ARM, provided some background information about the new processor's development: "We are helping partners to meet particular market opportunities, especially in fully autonomous vehicles and robotics systems where specific functionality is required for safety-critical tasks." To meet the industry safety standards ARM has documented the strict development process, fault modelling and supporting software isolation for the Cortex-R52.

Coming soon to a CPU near you: reconfigurable chaos. “We propose utilizing chaos theory – the system’s own nonlinearity – to enable transistor circuits to be programmed to perform different tasks. A very simple nonlinear transistor circuit contains very rich patterns. Different patterns that represent different functions coexist within the nonlinear dynamics of the system, and they are selectable. We utilize these dynamics-level behaviors to perform different processing tasks using the same circuit. As a result we can get more out of less.”

Meanwhile an AMD A12-9800 APU has been overclocked to 4.8GHz on stock cooling. A Korean overclocker, Namegt, has reached 4.8GHz on AMD's new A12-9800 APU using AMD's Wraith Air cooler at a voltage of 1.325V. This is a huge improvement on the overclockability of AMD's older Kaveri APUs, which require much larger cooling solutions and higher voltage in order to achieve the same clock speeds. This overclock is 1GHz higher than A12-9800's base clock speed of 3.8GHz and 0.6GHz higher than this CPUs boost clock speeds of 4.2GHz, which is an impressive overclock given the fact that this CPU is still using AMD's reference CPU cooler design.
