Kernel prepatch 4.8-rc6

h, 2016-09-12 14:42
Linus has released the 4.8-rc6 kernel prepatch. "I still haven't decided whether we're going to do an rc8, but I guess I don't have to decide yet. Nothing looks particularly bad, and it will depend on how rc7 looks."

Abbott: Success with Interns

szo, 2016-09-10 01:16

Laura Abbott marks the end of the latest round of open-source internships at Outreachy with a blog post reflecting on "what makes an internship successful," especially as seen in the kernel team's internships. Among Abbott's lessons: "Choose your tasks carefully. Tasks with a specific goal but multiple ways to solve are best. Too open ended tasks can be frustrating for all involved but there should be some chance for decision making. Just giving a list of tasks and exactly how they should be completed isn't good for learning. Give your intern a chance to propose a solution and then review it together." Also: "Speaking of review, code review is a skill. Model how to respond to code review comments. Encourage interns to practice reviewing others code and ask questions as well." That is just a sampling; in total, Abbott lists well over a dozen take-aways from the experience, all worth reading.

A bite of Python (Red Hat Security Blog)

cs, 2016-09-08 19:59
On the Red Hat Security Blog, Ilya Etingof describes some traps for the unwary in Python, some that have security implications. "Being easy to pick up and progress quickly towards developing larger and more complicated applications, Python is becoming increasingly ubiquitous in computing environments. Though apparent language clarity and friendliness could lull the vigilance of software engineers and system administrators -- luring them into coding mistakes that may have serious security implications. In this article, which primarily targets people who are new to Python, a handful of security-related quirks are looked at; experienced developers may well be aware of the peculiarities that follow."

[$] What's next for Apache OpenOffice

cs, 2016-09-08 11:00
Concerns about the viability of the Apache OpenOffice (AOO) project are not new; they had been in the air for a while by the time LWN looked at the project's development activity in early 2015. Since then, though, the worries have grown more pronounced, especially after AOO's recent failure to produce a release with an important security fix nearly one year after being notified of the vulnerability. The result is an internal discussion on whether the project should be "retired," or whether it will find a way to turn its fortunes around.

[$] An asynchronous Internet in GNOME

cs, 2016-09-08 06:57

At GUADEC 2016 in Karlsruhe, Germany, Jonathan Blandford challenged the GNOME project to rethink how its desktop software uses network access. The GNOME desktop assumes Internet connectivity is always available, which has the side effect of making the software stack considerably less useful and, indeed, usable to people who live in those places regarded as the developing world.

Danko: Next steps for Gmane

k, 2016-09-06 21:01
LWN previously reported that Gmane creator and maintainer Lars Magne Ingebrigtsen shut down the website and was contemplating shutting down the service entirely. Martin Danko now reports that Gmane has a new maintainer. "I petitioned some of our directors to allow us to offer to take it over and in the end we entered into agreement with Lars to take over Gmane. The assets of Gmane have been placed into a UK company Gmane Ltd. As part of the agreement, we have received the INN spool with all the articles but none of the code that drives the site. We’ve started rebuilding parts of the site just to get it back online, its not perfect and there are pieces missing but we’re working on building all the functionality back into the site."

Kernel prepatch 4.8-rc5

h, 2016-09-05 08:56
The 4.8-rc5 kernel prepatch is available for testing. "So rc5 is noticeably bigger than rc4 was, and my hope last week that we were starting to calm down and shrink the releases seems to have been premature. [...] Not that any of this looks worrisome per se, but if things don't start calming down from now, this may be one of those releases that will need an rc8. We'll see."

Z-Wave protocol specification now public

szo, 2016-09-03 00:58

The Z-Wave wireless home-automation protocol has been released to the public. In years past, the specification was only available to purchasers of the Z-Wave Alliance's development kit, forcing open-source implementations to reverse-engineer the protocol. The official press release notes that there are several such projects, including OpenZWave; Z-Wave support is also vital to higher-level Internet-of-Things abstraction systems like AllJoyn.

The US Department of Justice has announced that it has arrested a suspect in the 2011 kernel.org breakin. "[Donald Ryan] Austin is charged with causing damage to four servers located in the Bay Area by installing malicious software. Specifically, he is alleged to have gained unauthorized access to the four servers by using the credentials of an individual associated with the Linux Kernel Organization. According to the indictment, Austin used that access to install rootkit and trojan software, as well as to make other changes to the servers."
