Kernel 3.17 and kdbus – the kernel column

Filed under
Linux

Linus Torvalds announced the first release candidate 3.17 kernel (RC1) just ahead of this year’s Kernel Summit. Noting that he would be travelling (and thus not able to keep up with a massive influx of patches), he had closed the “merge window” (the period of time during which disruptive churn is allowed in any kernel development cycle) for 3.17 one day early. He also noted that, typically of northern hemisphere summers, this merge window had been “slightly smaller than the last few ones”. New features pulled into 3.17-rc1 were spread all over the kernel. They include the getrandom() system call, and support for the “memfd” and “file sealing” features needed for kdbus.

F2FS File-System Gets Even Better With Linux 3.18

Filed under
Linux

The Flash-Friendly File-System (F2FS) has been running well in our latest SSD benchmarks but with the forthcoming Linux 3.18 kernel it's going to be in even better shape.

Jaegeuk Kim, formerly of Samsung, sent in his F2FS pull request on Wednesday for the 3.18 merge window. Features of the F2FS file-system with this next kernel include support for large sector sizes, FITRIM support, and atomic/volatile writes. There's also enhancements to the check-point speed and roll-forward speed. F2FS for Linux 3.18 also retains some recovery information from fsck.f2fs, enhances the flush command management, fixes a bug in lseek, tunes in-place-update policies, and revisits all the roll-forward and fsync rules.

Time to Replace XFCE?

Filed under
GNU
Linux

According to my sources, the last stable release of XFCE was about two years ago. By anyone's time line, that is a long time between stable releases. Bundle this issue with its apparent inability to play nicely with GTK3 friendly items and instead sticking to its older GTK roots. And others users have pointed out that the perceived GTK3 issues are largely with various desktop themes and the "fault" is to be directed at the GNOME project. Long story short, it's a debate showing few signs of being resolved anytime soon.

On the other hand, 2014 has seen updates to features such as the XFCE power manager, a bug fix to be exact. So it's clear the project isn't completely stalled. Instead, it just feels like XFCE is set in their legacy mindset and has little interest in evolving.

Linux 3.18 Improves FocalTech, Razer Sabertooth & Other Input Devices

Filed under
Linux

Highlights of the Linux 3.18 input changes include a TI haptics/vibrator drv260x driver (DRV2667) written by Texas Instruments themselves, the Xpad driver can now properly identify the Razer Sabertooth game controller, support for detecting FocalTech PS/2 touch-pads, a haptic driver for the max77693, and other changes. The PID/VID mappings for the Razer Sabertooth make it recognize as an Xbox 360 controller rather than generic Xbox controller.

Everyone Has Different Views On The "Open-Source Community"

Filed under
Linux
OSS
Misc

Meanwhile, Michael Hall of the Ubuntu camp wrote a post entitled the open-source community is wonderful. Hall says the community isn't perfect but it's still wonderful. He cites that mono-culture is dangerous, good people are humans too, and to love the whole rather than parts. "There are some annoying, obnoxious people in our family. There are good people who are sometimes annoying and obnoxious. But neither of those truths changes the fact that we are still a part of an amazing, inspiring, wonderful community of open source contributors and enthusiasts."

Systemd 217 Will Introduce Its New "Consoled" User Console Daemon

Filed under
Linux
Red Hat

Back in August I wrote about systemd working to create a new user-space VT solution that could eventually succeed the Linux kernel's VT support. With the upcoming systemd 217 release, the terminal is present.

David Herrmann has been landing a lot of changes into systemd over the past few weeks working on the project's terminal. As of a few weeks ago, there's now a consoled. The systemd-consoled is a user console daemon that's currently rather basic and does rather primitive rendering. Herrmann explained a bit:

5 Exciting New Features in Linux 3.17

Filed under
Linux

Though he had at one point been hoping for an early release, Linus Torvalds unleashed version 3.17 of the Linux kernel on Sunday, thereby sticking to the "normal" schedule after all.

"The past week was fairly calm, and so I have no qualms about releasing 3.17 on the normal schedule (as opposed to the optimistic 'maybe I can release it one week early' schedule that was not to be)," Torvalds wrote in the official announcement.

Watch a working Project Ara prototype demonstrated ahead of Spiral 2 reveal

The engineers behind Project Ara are trying to make the last smartphone you'll ever need. Their design for a modular device has users slotting components — a camera, extra storage space, a Wi-Fi connector — into their phones, as and when they need them. It's an ambitious scheme, but engineers working at NK Labs in Boston have already produced a working prototype, which they showed off to modular smartphone evangelist Dave Hakkens during a recent visit.

Interview with Jessica Tallon of PyPump

There are several interesting projects out there which use PyPump. With my day job as a GNU MediaGoblin developer, we're going to be using it as a way of communicating between servers as a part of our federation effort. A great use I've seen is PumpMigrate, which will migrate one pump.io account to another. Another little utility that I wrote over the course of a weekend is p, which was made to be an easy way of making a quick post, bulk uploading photos, or anything you can script with the shell.

Black Lab Education Desktop 6.0.1 to Be Supported Until 2022

There are numerous Linux distributions that are oriented towards education, but you can never have too many in a domain such as this one. It's based on the Black Lab Professional Desktop, which is a very good and powerful solution. Interestingly enough, Black Lab Linux is actually based on Ubuntu, and the latest one uses the 14.04.1 base (Trusty Tahr). Just like the base that is used for this distribution, the desktop environment used is GNOME 3, but with a few extensions to make it somewhat different from the stock version and to provide users with better functionality. One of the most interesting aspects of this operating system is the fact that it has a very long support period, which, in theory, it should end in 2022. Read more
