Ingebrigtsen: Whatever Happened To news.gmane.org?

수, 2020/01/08 - 4:18오전
Lars Ingebrigtsen provides details on the current status of the Gmane archive server and asks for feedback on whether it is still useful. "Over the past few years, people have asked me what happened to Gmane, and I’ve mostly clasped my hands over my ears and gone 'la la la can’t hear you', because there’s nothing about the story I’m now finally going to tell that I don’t find highly embarrassing. I had hoped I could just continue that way until I die, but perhaps it would be more constructive to actually tell people what’s going on instead of doing an ostrich impression." (Thanks to Giovanni Gherdovich).

[$] Removing the Linux /dev/random blocking pool

화, 2020/01/07 - 12:51오후
The random-number generation facilities in the kernel have been reworked some over the past few months—but problems in that subsystem have been addressed over an even longer time frame. The most recent changes were made to stop the getrandom() system call from blocking for long periods of time at system boot, but the underlying cause was the behavior of the blocking random pool. A recent patch set would remove that pool and it would seem to be headed for the mainline kernel.

Kernel prepatch 5.5-rc5 and stable updates

월, 2020/01/06 - 9:24오전
The 5.5-rc5 kernel prepatch has been released. Linus added a note to the release announcement: "One sad piece of news I got this past week was that Bruce Evans has passed away. Bruce wasn't really ever really much directly involved in Linux development - he was active on the BSD side - but he was the developer behind Minix/i386, which was what I used for the original Linux development in the very early days before Linux became self-hosting."

On the stable-update side, 5.4.8, 4.19.93, 4.14.162, 4.9.208, and 4.4.208 are all available with another set of important fixes.

[$] Some median Python NaNsense

토, 2020/01/04 - 7:11오전
Anybody who has ever taken a numerical analysis course understands that floating-point arithmetic on computers is a messy affair. Even so, it is easy to underestimate just how messy things can be. This topic came to the fore in an initially unrelated python-ideas mailing-list thread; what should the Python statistics module do with floating-point values that are explicitly not numbers?

The Schism at the Heart of the Open-Source Movement (The Atlantic)

토, 2020/01/04 - 6:16오전
It is not all that often that the mainstream press looks at issues in the open-source world, but this article from The Atlantic does just that; it looks at the controversy surrounding GitHub renewing its contract with the US Immigration and Customs Enforcement (ICE) agency and the concerns some have had with their code being used by ICE. "So when news of GitHub’s contract with ICE emerged, its employees weren’t the only ones outraged. Because of the transitive nature of open source, volunteer developers—who host code on the site to share with others—may have unwittingly contributed to the code GitHub furnished for ICE, the agency responsible for enforcing immigration policy. Some were troubled by the idea that their code might in some way be used to help agents detain and deport undocumented migrants. But their outrage—and the backlash to it—reveals existential questions about the very nature of open source."

[$] A medley of performance-related BPF patches

금, 2020/01/03 - 7:49오전
One of the advantages of the in-kernel BPF virtual machine is that it is fast. BPF programs are just-in-time compiled and run directly by the CPU, so there is no interpreter overhead. For many of the intended use cases, though, "fast" can never be quite fast enough. It is thus unsurprising that there are currently a number of patch sets under development that are intended to speed up one aspect or another of using BPF in the system. A few, in particular, seem about ready to hit the mainline.

Ruby 2.7 released

금, 2020/01/03 - 2:46오전
Over the holiday week, we missed the announcement of Ruby 2.7 on December 25. It is the most recent release of the Ruby programming language and was more than a year in development. There are quite a few new features including experimental pattern matching for case statements (more information can be found in these slides), a new compaction garbage collector for the heap, support for separating positional and keyword arguments, and plenty more.

[$] Python first()

목, 2020/01/02 - 5:18오전
Python prides itself on being a newbie-friendly language; its developers have gone out of their way to try to ensure that easy tasks are straightforward to program. A recent discussion on the python-ideas mailing list looked at a use case that is common, but often implemented in an inefficient, incorrect fashion, with an eye toward making it easier to do correctly. Finding the first match for a regular expression in a body of text is where the conversation started, but it went in some other interesting directions as well.

[$] LWN's 2020 vision

목, 2020/01/02 - 5:14오전
January 1, 2020 marks the beginning of a new year and a new decade. Many things will doubtless change over the course of this year in the free-software community and beyond, while others will remain the same. One thing that will certainly hold true is LWN's tradition of starting the new year with some ill-advised predictions about what may be in store. Your editor has no special vision, but neither does he fear being proved badly wrong in a public setting — it's all in a day's work.

[$] Fedora and fstrim

수, 2020/01/01 - 7:20오전
A proposal to periodically run the fstrim command on Fedora 32 systems was discussed recently on the Fedora devel mailing list. fstrim is used to cause a filesystem to inform the underlying storage of unused blocks, which can help SSDs and other types of block devices perform better. There were a number of questions and concerns raised, including whether to change the behavior of earlier versions of the distribution when they get upgraded and if the kernel should be responsible for handling the whole problem.
