[$] Darling: macOS compatibility for Linux

수, 2019/07/31 - 1:54오전
There is an increasingly active development effort, known as Darling, that is aiming to provide a translation layer for macOS software on Linux; it is inspired in part by Wine. While Darling isn't nearly as mature as Wine, contributors are continuing to build out capabilities that could make the project more useful to a wider group of users in the future.

Subscribers can read on for a look at Darling from this week's edition.

Kernel prepatch 5.3-rc2

월, 2019/07/29 - 5:29오전
The 5.3-rc2 kernel prepatch is available for testing. "There are fixes all over, I don't think there's much of a pattern here. The three areas that do stand out are Documentation (more rst conversions), arch updates (mainly because of the netx arm platform removal) and misc driver fixes (gpu, iommu, net, nvdimm, sound ..)".

GitHub starts blocking developers in countries facing US trade sanctions (ZDNet)

토, 2019/07/27 - 11:46오후
ZDNet reports on GitHub's blocking of users from Crimea and Iran. "As GitHub notes on its page about US trade controls, US sanctions apply to its online hosting service, GitHub.com, but its paid-for on-premise software -- aimed at enterprise users -- may be an option for users in those circumstances. It also claims to be in discussions with US regulators about how to rectify the situation."

[$] Completing the pidfd API

토, 2019/07/27 - 5:27오전
Over the last few kernel releases, the kernel has gained the concept of a "pidfd" — a file descriptor that represents a process. What started as a way of sending signals to processes without race conditions has evolved into a more complete process-management interface. Now one of the last pieces is being put into place: the ability to wait for processes using pidfds. But, naturally, that API has had to go through some revisions first.

[$] Access to complex video devices with libcamera

금, 2019/07/26 - 6:13오전
Laurent Pinchart began his Open Source Summit Japan 2019 talk with a statement that, once upon a time, camera devices were simple pipelines that produced a sequence of video frames. Applications could control cameras using the Video4Linux (V4L) API by way of a single device node; there were "lots of knobs", but the overall task was straightforward. That situation has changed over the years, and application developers need more help; that is where the libcamera project comes in.

[$] Python "standard" library

목, 2019/07/25 - 4:33오전
Python is often mentioned in the same breath with the phrase "batteries included", which refers to the breadth of its standard library. But there is an effort underway to trim back the standard library by removing some unloved modules. In addition, there has been persistent talk of a major restructuring of the library, into a fairly minimal core as described in Amber Brown's talk at this year's Python Language Summit, or in other ways as discussed on the python-dev mailing list in January (though it has come up many times before that as well). A mid-July python-ideas mailing list thread picked up on some of that; it ended up showing, once again, that there is no real consensus on what the standard library is—or should be.

Fedora Magazine covers the first preview release of Fedora CoreOS, a new Fedora edition built specifically for running containerized workloads. "It's the successor to both Fedora Atomic Host and CoreOS Container Linux. Fedora CoreOS combines the provisioning tools, automatic update model, and philosophy of Container Linux with the packaging technology, OCI support, and SELinux security of Atomic Host."

[$] Protecting update systems from nation-state attackers

수, 2019/07/24 - 11:56오후
Frequent updates are a key part of keeping systems secure, but that goal will not be met if the update mechanism itself is compromised by an attacker. At a talk during the 2019 Open Source Summit Japan, Justin Cappos described Uptane, an update delivery mechanism for automotive applications that, he said, can prevent such problems, even when the attacker has the resources of a nation state. It would seem that some automobile manufacturers agree.

[$] Accessing zoned block devices with zonefs

수, 2019/07/24 - 6:15오전
Zoned block devices are quite different than the block devices most people are used to. The concept came from shingled magnetic recording (SMR) devices, which allow much higher density storage, but that extra capacity comes with a price: less flexibility. Zoned devices have regions (zones) that can only be written sequentially; there is no random access for writes to those zones. Linux already supports these devices, and filesystems are adding support as well, but some applications may want a simpler, more straightforward interface; that's what a new filesystem, zonefs, is targeting.
