Doing VFX Work in Linux? Here’s Your Reference Platform

Filed under
GNU
Linux

The Visual Effects Society (VES) has released its Calendar Year 2014 Reference Platform, which specifies versions of different Linux tools and libraries as a target for VFX software. VES said the platform aims to minimize incompatibilities, make it easier to support Linux pipelines, and encourage more software vendors to release tools that run on Linux.

Anyone who's done much work on Linux systems knows about the tangles that can arise when different software packages rely on different iterations of crucial libraries. Standardizing a baseline set of tools for installation on a VFX-ready Linux workstation should help, assuming vendors cooperate and users are made aware of the recommendations. To that end, the VES plans to announce the 2015 version of the platform at SIGGRAPH, and is currently inviting industry feedback on its draft version.

Wink's Linux Hub and Mobile App Take on Home Automation

Filed under

Linux

The flood of Linux-based home automation hubs that has arrived over the last two years is now being joined by a wave of intermediary solutions that integrate multiple ecosystems. One of the most promising is Wink, a spinoff from crowd-investment firm Quirky. A week after announcing its Linux-based Wink home automation hub and mobile app, the well-heeled startup demonstrated the technology in a model smart home launch event in New York City, and announced 15 partners and 60 compatible devices.

Wink also released its Javascript-based API to developers interested in building Wink apps for the supported Android and iOS platforms. Last week, Wink announced it will also ship an Android Wear version that will run on Android Wear smartwatches like the LG G Watch and Samsung Gear Live. The Android Wear app will communicate with devices via the full Android smartphone app, rather than directly, and will offer more limited features.

Intel Linux Driver Trying Bay Trail Aggressive Downclocking

Filed under
Linux

Intel's Linux open-source crew is toying with aggressive down-clocking for current-generation Bay Trail hardware for greater power-savings and lower heat output.

Chris Wilson of Intel OTC has proposed a patch to be more aggressive about down-clocking -- dropping the Atom/Celeron SoCs to their lower frequency/power states more quickly after being in a ramped-up state. Assuming the workload has finished, this should yield a quicker return to the lowest power state for maximum power-savings / longest battery life and lower heat output.

NSA: Linux Journal is an "extremist forum" and its readers get flagged for extra surveillance

Filed under
Linux
Security

A new story published on the German site Tagesschau and followed up by BoingBoing and DasErste.de has uncovered some shocking details about who the NSA targets for surveillance including visitors to Linux Journal itself.

While it has been revealed before that the NSA captures just about all Internet traffic for a short time, the Tagesschau story provides new details about how the NSA's XKEYSCORE program decides which traffic to keep indefinitely. XKEYSCORE uses specific selectors to flag traffic, and the article reveals that Web searches for Tor and Tails--software I've covered here in Linux Journal that helps to protect a user's anonymity and privacy on the Internet--are among the selectors that will flag you as "extremist" and targeted for further surveillance. If you just consider how many Linux Journal readers have read our Tor and Tails coverage in the magazine, that alone would flag quite a few innocent people as extremist.

Docker and Linux containers: Red Hat opens up on the issues

Filed under
Linux
Red Hat

Red Hat's platform business vice president Jim Totton believes the current focus on containers could signal the growth of an alternative type of computing architecture — but says it's not yet clear how people will apply the technology.

Elements of container technology have existed in Linux in the form of cgroups since 2006 and in UNIX for decades. Containers sit on top of a single Linux instance and are a lighter-weight form of virtualisation, each capable of running an isolated app on a reduced OS under the control of a resources policy.

10 tips for a more user-friendly Linux desktop

Filed under
GNU
Linux

The Linux desktop is leaps and bounds from where it was 10, five, even two years ago. Desktop environments that many declared unusable or dead have seen a renaissance in usability. But that doesn't mean that out of the box, every Linux desktop is ready for every type of user. For each user type there may be many ways to make a desktop more usable. Thankfully, this is Linux -- so options are never a problem.

With that in mind, I wanted to highlight my 10 best tips for creating more user-friendly Linux desktops. Not every one of these tips will apply to your particular desktop (be it GNOME, Unity, KDE, XFCE, Deepin Desktop, Cinnamon... the list goes on). But you should find more than one tip that will go a long way toward improving your experience.

A DRM-fixes pull request for the open-source Radeon Linux graphics driver for the Linux 3.16 kernel is going to enable BAPM by default for some APU systems.

BAPM is a power management feature that handles power budgeting between the CPU/GPUs on APUs. Up to now BAPM has been disabled by default, but for fixing some power-related bugs, this feature is looking to be turned on post-3.16 merge window for some AMD APU hardware.

The SUSE method for live kernel patching, kGraft, is being proposed for possible inclusion into the linux-next branch in hopes it will be merged into an upcoming Linux kernel release cycle.

The kGraft patches for live kernel patching continue to be revised and reviewed but at the same time there's still Kpatch that's been developed by Red Hat with some different design principles for updating the running kernel in real-time. To date there's been no general consensus on the superior solution nor any agreement to try to merge Kpatch and kGraft.
