MorphOS 2.7 has been released, and it’s mostly a bug-fix release. The one thing that stood out to me is that some work has gone into fixing bugs for several PowerPC G4 chips – more specifically, models used in PowerBook G4s. MorphOS has been demonstrated on the PowerBook G4, but official support for it has not been released yet.

Verve: A Type Safe Operating System

“The Singularity project (an OS written in managed code used for research purposes) has provided several very useful research results and opened new avenues for exploration in operating system design. Recently, MSR released a paper covering an operating system research project that takes a new approach to building an OS stack with verifiable and type safe managed code. This project employs a novel use of Typed Assembly Language, which is what you think it is: Assembly with types (implemented as annotations and verified statically using the verification technology Boogie and the theorem prover Z3 (Boogie generates verification conditions that are then statically proven by Z3. Boogie is also a language used to build program verifiers for other languages)). As with Singularity, the C# Bartok compiler is used, but this time it generates TAL. The entire OS stack is verifiably type safe (the Nucleus is essentially the Verve HAL) and all objects are garbage collected. It does not employ the SIP model of process isolation (like Singularity). In this case, again, the entire operating system is type safe and statically proven as such using world-class theorem provers.” Channel9 has an interview on video with one of the developers behind this MSR project. Source code to Verve is available.

Steve Jobs recently told a Mac user, enquiring about the probability of USB3 on Macs in the near feature, that the technology is not ready because Intel has yet to adopt the platform. A recent rumour slated Intel to integrate USB3 it into its chipsets by no earlier than 2012.
LaCie electronics, however, is not prepared to wait around until 2012, and has just released an USB3.0 driver for Mac OS X. Just one catch: it only works with LaCie’s hardware.

An anonymous reader writes “Phoronix has published benchmarks of the past five years worth of Linux kernel releases, from the Linux 2.6.12 through Linux 2.6.37 (dev) releases. The results from these benchmarks of 26 versions show that, for the most part, new features haven’t affected performance.”

Mortimer.CA writes “The release of OpenBSD 4.8 has been announced. Highlights include ACPI suspend/resume, better hardware support, OpenBGPD/OpenOSPFD/routing daemon improvements, inclusion of OpenSSH 5.5, etc. Nothing revolutionary, just the usual steady improving of the system.

geek4 writes with this excerpt from eWeek Europe: “An analysis of Google Android Froyo’s open source kernel has uncovered 88 critical flaws that could expose users’ personal information. An analysis of the kernel used in Google’s Android smartphone software has turned up 88 high-risk security flaws that could be used to expose users’ personal information, security firm Coverity said in a report published on Tuesday. The results, published in the 2010 edition of the Coverity Scan Open Source Integrity Report, are based on an analysis of the Froyo kernel used in HTC’s Droid Incredible handset. … While Android implementations vary from device to device, Coverity said the same flaws were likely to exist in other handsets as well. Coverity uncovered a total of 359 bugs, about one-quarter of which were classified as high-risk.”
