Rediscovering RISC-V: Apple M1 Sparks Renewed Interest in Non-x86 Architecture

“With the runaway success of the new ARM-based M1 Macs, non-x86 architectures are getting their closeup,” explains a new article at ZDNet. “RISC-V is getting the most attention from system designers looking to horn-in on Apple’s recipe for high performance. Here’s why…” RISC-V is, like x86 and ARM, an instruction set architecture (ISA). Unlike x86 and ARM, it is a free…

Developer Successfully Virtualizes Windows for Arm on M1 Mac

Developer Alexander Graf has successfully virtualized the Arm version of Windows on an M1 Mac, proving that the M1 chip is capable of running Microsoft’s operating system. From a report: Currently, Macs with the M1 chip do not support Windows and there is no Boot Camp feature as there is on Intel Macs, but support for Windows is a feature that…

4.5-bil­lion-year-old ice on comet ‘fluffi­er than cap­puc­ci­no froth’

After years of detective work, scientists working on the European Space Agency (ESA) Rosetta mission have now been able to locate where the Philae lander made its second and penultimate contact with the surface of Comet 67P/Churyumov-Gerasimenko on 12 November 2014, before finally coming to a halt 30 metres away. This landing was monitored from the German Aerospace Center Philae Control…
