OpenBSD
Theo de Raadt announced the release of OpenBSD 6.6 on October 17, 2019. Marquee features include a new system upgrade tool, an AMD GPU driver, upgrades to core systems daemons ntpd and smtpd, and other platform improvements.
Linux 5.1 released has just been released. The main feature in this release is io_uring, a high-performance interface for asynchronous I/O. There are also improvements in fanotify to provide a scalable way of watching changes on large file systems, and it adds a method to allow safe delivery of signals in presence of PID reuse. Persistent memory can be used now as hot-plugabble RAM, Zstd compression levels have been made configurable in Btrfs, and there is a new cpuidle governor that makes better power management decisions than the menu governor. In addition, all 32 bit architectures have added the necessary syscalls to deal with the y2038 problem; and live patching has added support for creating cumulative patches. There are many other features and new drivers in the KernelNewbies changelog.

When OSNews covered the RISC V architecture recently, I was struck by my own lack of excitement. I looked into it, and the project looks intriguing, but it didn’t move me on an emotional level like a new CPU architecture development would have done many years ago. I think it’s due to a change in myself, as I have got older. When I first got into computers, in the early 80s, there was a vibrant environment of competing designs with different approaches. This tended to foster an interest, in the enthusiast, in what was inside the box, including the CPU architecture. Jump forwards to the current era, and the computer market is largely homogenized to a single approach for each class of computing device, and this means that there is less to get excited about in terms of CPU architectures in general. I want to look at what brought about this change in myself, and maybe these thoughts will resonate with some of you.

Two bits of related news; the 4.0 release of GlideN64, the most-compatible High-Level-Emulation graphics plugin for N64 emulators: but more interestingly, this story about the struggle to reverse-engineer the GPU microcode used in Indiana Jones and the Infernal Machine and Star Wars Episode I: Battle for Naboo that have eluded developers for decades.
