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.

Linux

Con Kolivas has updated his out-of-tree process scheduler for the Linux kernel.

The Brain Fuck Scheduler has been revised to version 448 and released on Wednesday for the Linux 3.15 stable kernel.

Besides updating against the kernel interfaces of Linux 3.15, there's no reports of other changes for the BFS scheduler with the v448 revision. Kolivas continues to have no desire to mainline the Brain Fuck Scheduler.

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.

Linux 3.16 Aims To Enable Radeon BAPM By Default

Filed under
Linux

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.

kGraft Being Discussed For Inclusion Into Linux-Next

Filed under
Linux
SUSE

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.

KDE and GNOME: Kubuntu, Krita, GNOME Development

  • Kubuntu 18.04 LTS Could Switch to Breeze-Dark Plasma Theme by Default, Test Now
    The latest daily build live ISO images that landed earlier today for Kubuntu 18.04 LTS (Bionic Beaver) apparently uses the Breeze-Dark Plasma theme for the KDE Plasma 5.11 desktop environment by default. However, we've been told that it's currently an experiment to get the pulse of the community. "Users running [Kubuntu] 18.04 development version who have not deliberately opted to use Breeze/Breeze-Light in their System Settings will also see the change after upgrading packages," said the devs. "Users can easily revert back to the Breeze/Breeze-Light Plasma themes by changing this in System Settings."
  • Interview with Rytelier
    The amount of convenience is very high compared to other programs. The amount of “this one should be designed in a better way, it annoys me” things is the smallest of all the programs I use, and if something is broken, then most of these functions are announced to improve in 4.0.
  • Grow your skills with GNOME
    For the past 3 years I’ve been working very hard because I fulfill a number of these roles for Builder. It’s exhausting and unsustainable. It contributes to burnout and hostile communication by putting too much responsibility on too few people’s shoulders.

  • A Lot Of Improvements Are Building Up For GIMP 2.9.8, Including Better Wayland Support
    It's been four months since the release of GIMP 2.9.6 and while GIMP 2.9 developments are sadly not too frequent, the next GIMP 2.9.8 release is preparing a host of changes. Of excitement to those trying to use GIMP in a Wayland-based Linux desktop environment, GIMP's color picker has just picked up support for working on KDE/Wayland as well as some other Color Picker improvements to help GNOME/Wayland too. GIMP's Screenshot plugin also now has support for taking screenshots on KDE/Wayland either as a full-screen or individual windows. Granted, GIMP won't be all nice and dandy on Wayland itself until seeing the long-awaited GTK3 (or straight to GTK4) port.

  • The art of the usability interview
    During a usability test, it's important to understand what the tester is thinking. What were they looking for when they couldn't find a button or menu item? During the usability test, I recommend that you try to observe, take notes, capture as much data as you can about what the tester is doing. Only after the tester is finished with a scenario or set of scenarios should you ask questions.

Clang's default C++ dialect is now GNU++14 version of C++14 rather than GNU++98 (C++98). The older versions of the C++ standard remain available and can be set via the -std= argument, just as those previously could have specified C++11 / C++14 / C++17, but now in cases where not specified, GNU++14/C++14 is the default.
