[$] Code, conflict, and conduct

2시간 4분 지남
A couple of surprising things happened in the kernel community on September 16: Linus Torvalds announced that he was taking a break from kernel development to focus on improving his own behavior, and the longstanding "code of conflict" was replaced with a code of conduct based on the Contributor Covenant. Those two things did not quite come packaged as a set, but they are clearly not unrelated. It is a time of change for the kernel project; there will be challenges to overcome but, in the end, less may change than many expect or fear.

Versity announces next generation open source archiving filesystem

화, 2018/09/18 - 8:15오전
Versity Software has announced that it has released ScoutFS under GPLv2. "ScoutFS is the first GPL archiving file system ever released, creating an inherently safer and more user friendly option for storing archival data where accessibility over very large time scales, and the removal of vendor specific risk is a key consideration."

Apache SpamAssassin 3.4.2 released

월, 2018/09/17 - 10:30오후
SpamAssassin 3.4.2 is out, the first release from this spam-filtering project since 3.4.1 came out in April 2015. It fixes some remotely exploitable security issues, so SpamAssassin users probably want to update in the near future. "The exploit has been seen in the wild but not believe to have been purposefully part of a Denial of Service attempt.  We are concerned that there may be attempts to abuse the vulnerability in the future.  Therefore, we strongly recommend all users of these versions upgrade to Apache SpamAssassin 3.4.2 as soon as possible."

[$] Fedora reawakens the hibernation debate

월, 2018/09/17 - 9:52오후
Behavioral changes can make desktop users grumpy; that is doubly true for changes that arrive without notice and possibly risk data loss. Such a situation recently arose in the Fedora 29 development branch in the form of a new "suspend-then-hibernate" feature. This feature will almost certainly be turned off before Fedora 29 reaches an official release, but the discussion and finger-pointing it inspired reveal some significant differences of opinion about how this kind of change should be managed.

Kernel prepatch 4.19-rc4; Linus taking a break

월, 2018/09/17 - 7:06오전
Linus has released 4.19-rc4 and made a set of announcements that should really be read in their entirety. "I actually think that 4.19 is looking fairly good, things have gotten to the 'calm' period of the release cycle, and I've talked to Greg to ask him if he'd mind finishing up 4.19 for me, so that I can take a break, and try to at least fix my own behavior."

Lights, Camera, Open Source: Hollywood Turns to Linux for New Code Sharing Initiative (Linux Journal)

토, 2018/09/15 - 6:59오전
Linux Journal covers the new Academy Software Foundation (ASWF), which is a project aimed at open-source collaboration in movie-making software that was started by the Academy of Motion Picture Arts and Sciences (AMPAS) and the Linux Foundation. "Still at the early stages, the ASWF has yet to develop any of its own projects, but there is interest in having them host a number of very popular projects, such as Industrial Light & Magic’s OpenEXR HDR image file format, color management solution OpenColorIO, and OPenVDB, which is used for working with those hard-to-handle objects like clouds and fluids. Along with promoting cooperation on the development of a more robust set of tools for the industry, one of the goals of the organization moving forward is to put out a shared licensing template that they hope will help smooth the tensions over licensing. It follows that with the growth of projects, navigating the politics over usage rights is bound to be a tricky task."

The (awesome) economics of open source

금, 2018/09/14 - 9:11오전
Over at Opensource.com, Red Hat's Michael Tiemann looks at open source from the perspective of the economic theories of Ronald Coase, who won the 1991 Nobel Prize for Economics. Those theories help explain why companies like Red Hat (and Cygnus Solutions, which Tiemann founded) have prospered even in the face of economic arguments about why they should not. "Successful open source software companies 'discover' markets where transaction costs far outweigh all other costs, outcompete the proprietary alternatives for all the good reasons that even the economic nay-sayers already concede (e.g., open source is simply a better development model to create and maintain higher-quality, more rapidly innovative software than the finite limits of proprietary software), and then—and this is the important bit—help clients achieve strategic objectives using open source as a platform for their own innovation. With open source, better/faster/cheaper by itself is available for the low, low price of zero dollars. As an open source company, we don't cry about that. Instead, we look at how open source might create a new inflection point that fundamentally changes the economics of existing markets or how it might create entirely new and more valuable markets."

The first /e/ beta is available

금, 2018/09/14 - 5:07오전
/e/ is Gaël Duval's project to build a privacy-oriented smartphone distribution; the first beta is now available with support for a number of devices. "At our current point of development, we have an '/e/' ROM in Beta stage: forked from LineageOS 14.1, it can be installed on several devices (read the list). The number of supported devices will grow over time, depending on more build servers and more contributors who can maintain or port to specific devices (contributors welcome). The ROM includes microG configured by default with Mozilla NLP so users can have geolocation functionality even when GPS signal is not available."

[$] Compiling kernel UAPI headers with C++

금, 2018/09/14 - 1:47오전
Linux kernel developers tend to take a dim view of the C++ language; it is seen, rightly or wrongly, as a sort of combination of the worst (from a system-programming point of view) features of higher-level languages and the worst aspects of C. So it takes a relatively brave person to dare to discuss that language on the kernel mailing lists. David Howells must certainly be one of those; he not only brought up the subject, but is working to make the kernel's user-space API (UAPI) header files compatible with C++.

HHVM ending support for PHP

목, 2018/09/13 - 10:23오후
The HHVM project has announced that the Hack language and PHP will truly be going separate ways. The HHVM v3.30 release, due by the end of the year, will be the last to support code written in PHP. "Ultimately, we recommend that projects either migrate entirely to the Hack language, or entirely to PHP7 and the PHP runtime." HHVM was first announced in 2011 as a compiler for the PHP language.

[$] Machine learning and stable kernels

목, 2018/09/13 - 6:45오전

There are ways to get fixes into the stable kernel trees, but they require humans to identify which patches should go there. Sasha Levin and Julia Lawall have taken a different approach: use machine learning to distinguish patches that fix bugs from others. That way, all bug-fix patches could potentially make their way into the stable kernels. Levin and Lawall gave a talk describing their work at the 2018 Open Source Summit North America in Vancouver, Canada.

[$] Trying to get STACKLEAK into the kernel

목, 2018/09/13 - 2:06오전

The STACKLEAK kernel security feature has been in the works for quite some time now, but has not, as yet, made its way into the mainline. That is not for lack of trying, as Alexander Popov has posted 15 separate versions of the patch set since May 2017. He described STACKLEAK and its tortuous path toward the mainline in a talk [YouTube video] at the 2018 Linux Security Summit.
