[$] Scheduling for asymmetric Arm systems

화, 2020/12/01 - 3:15오전
The Arm processor architecture has pushed the boundaries in a number of ways, some of which have required significant kernel changes in response. For example, the big.LITTLE architecture placed fast (but power-hungry) and slower (but more power-efficient) CPUs in the same system-on-chip (SoC); significant scheduler changes were needed for Linux to be able to properly distribute tasks on such systems. For all their quirkiness, big.LITTLE systems still feature CPUs that are in some sense identical: they can all run any task in the system. What is the scheduler to do, though, if confronted with a system where that is no longer true?

pip 20.3 release

화, 2020/12/01 - 2:03오전
The Python Packaging Authority has announced the release of pip 20.3. There is some potential for disruption with this release. "The new resolver is now *on by default*. It is significantly stricter and more consistent when it receives incompatible instructions, and reduces support for certain kinds of constraints files, so some workarounds and workflows may break."

The new rules for Perl governance

목, 2020/11/26 - 1:29오전
The process of adopting a new governance model for the Perl project appears to be reaching an end; the new model is designed to look a lot like the one adopted by the Python project. "So, now Perl has two well-defined bodies involved in its governance: a core team of a few dozen and a steering council of three people. The core team sets the rules of Perl governance, votes on membership of the two groups, and delegates substantial decision making power to the steering council. The steering council has broad authority to make decisions about the development of the Perl language, the interpreter, and all other components, systems and processes that result in new releases of the language interpreter." The full description is available for those looking for the details.

[$] Mutt releases version 2.0

수, 2020/11/25 - 11:50오후
The venerable email client Mutt has just reached version 2.0. Mutt is different from the type of client that has come to dominate the email landscape—for one thing, it has no graphical interface. It has a long history that is worth a bit of a look, as are its feature set and extensive customizability. Version 2.0 brings several enhancements to Mutt's interface, configurability, and convenience, as well. In this article, readers who are unfamiliar with Mutt will learn about a different way to deal with the daily chore of wrangling their inboxes, while Mutt experts may discover some new sides to an old friend.

GNU Guix 1.2.0 released

화, 2020/11/24 - 3:22오전
GNU Guix, a functional package manager and associated free software distribution, was introduced eight years ago. The 1.2.0 release celebrates the anniversary. "A major highlight in this release is the ability to authenticate channels, which probably makes Guix one of the safest ways to deliver complete operating systems today. This was the missing link in our “software supply chain” and we’re glad it’s now fixed. The end result is that guix pull and related commands now cryptographically authenticate channel code that they fetch; you cannot, for instance, retrieve unauthorized commits to the official Guix repository."

Huang: Evaluating Precursor’s Hardware Security

화, 2020/11/24 - 3:06오전
For those who are interested in security at the hardware level, this blog post from Andrew 'bunnie' Huang is well worth a read. "Despite any claims you may have heard otherwise, tamper resistance is a largely unsolved problem. Any secrets committed to a non-volatile format are vulnerable to recovery by a sufficiently advanced adversary. The availability of near-atomic level microscopy, along with sophisticated photon and phonon based probing techniques, means that a lab equipped with a few million dollars worth of top-notch gear and well-trained technicians has a good chance of recovering secret key material out of virtually any non-volatile storage media. The hard part is figuring out where the secrets are located on the chip."

Kernel prepatch 5.10-rc5

월, 2020/11/23 - 9:24오전
The 5.10-rc5 kernel prepatch is out. "The 5.10 release candidates stubbornly keeps staying fairly big, even though by rc5 we really should be seeing things starting to calm down and shrink. There's nothing in here that makes me particularly nervous, but in pure numbers of commits, this is the largest rc5 we've had in the 5.x series."

[$] epoll_pwait2(), close_range(), and encoded I/O

토, 2020/11/21 - 2:50오전
The various system calls and other APIs that the kernel provides for access to files and filesystems has grown increasingly comprehensive over the years. That does not mean, though, that there is no need or room for improvement. Several relatively small additions to the kernel's filesystem-related API are under consideration in the development community; read on for a survey of some of this work.
