LXer: An introduction to the DomTerm terminal emulator for Linux

Wednesday 31st of January 2018 06:47:53 AM
DomTerm is a modern terminal emulator that uses a browser engine as a "GUI toolkit." This enables some neat features, such as embeddable graphics and links, HTML rich text, and foldable (show/hide) commands. Otherwise it looks and feels like a feature-full, standalone terminal emulator, with excellent xterm compatibility (including mouse handling and 24-bit color), and appropriate "chrome" (menus).read more

Phoronix: DNF Package Manager Is Now Available On Clear Linux

Wednesday 31st of January 2018 06:08:38 AM
While Clear Linux may be extremely performant as shown in our many benchmarks, its default repository serving "bundles" (their task-based approach to package management) can be a bit light if wanting to use this Intel open-source Linux distribution on the desktop. There has been yum available via a bundle while now next-gen Yum, DNF, is also now available on Clear Linux...

LXer: Linux Kernel 4.15:

Wednesday 31st of January 2018 04:42:05 AM
Linus Torvalds released version 4.15 of the Linux Kernel on Sunday, again, and for a second version in a row, a week later than scheduled. The culprits for the late release were the Meltdown and Spectre bugs, as these two vulnerabilities forced developers to submit major patches well into what should have been the last cycle. Torvalds was not comfortable rushing the release, so he gave it another week.

LXer: Refreshing old computers with Linux

Wednesday 31st of January 2018 03:39:11 AM
It's nearly impossible to enter a school these days without seeing an abundance of technology. Despite this influx of computers into education, funding inequity forces school systems to make difficult choices. Some educators see things as they are and wonder, "Why?" while others see problems as opportunities and think, "Why not?"Andrew Dobbie is one of those visionaries who saw his love of Linux and computer reimaging as a unique learning opportunity for his students.read more

TuxMachines: AMD AOCC 1.1 Shows Compiler Improvements vs. GCC vs. Clang

Wednesday 31st of January 2018 01:44:04 AM

A few days ago we found out that at the end of 2017 AMD quietly released their AOCC 1.1 C/C++ compiler. AOCC is AMD's compiler succeeding AMD Open64 that existed years ago as their optimized Fortran/C/C++ compiler for past CPU microarchitectures while the "AMD Optimizing C/C++ Compiler" is designed for current-generation Zen processors. Here are benchmarks of the new AMD AOCC 1.1 release compared to GCC 7, GCC 8, Clang 5.0, Clang 6.0, and Clang 7.0 SVN.

TuxMachines: Compact, low-power serial device gateway runs FreeRTOS on Cortex-M3

Wednesday 31st of January 2018 01:37:25 AM

Artila’s “Aport-213” is a low-power, industrial strength, single port serial-to-WiFi gateway that offers WiFi-based remote access to devices such as meters, sensors, and switches without requiring the development of wireless LAN drivers and security supplicants.

The Airport-213 is the newest member of Artila’s industrial communications gateways family. The device runs FreeRTOS on an unspecified 166MHz Cortex-M3 SoC, and offers 802.11 wireless connectivity to serially-interfaced devices for monitoring and control functions. The compact, low-power device can be configured as a transparent bridge, allowing a serial device to be accessed wirelessly without requiring modifications to existing software, says the company.

Reddit: How do I get past the intermediate stage of whatever I'm trying to learn?

Wednesday 31st of January 2018 01:05:17 AM

Recently, I've noticed that I become just good enough with certain applications. Nothing more.

For example, vim. I've been using it for years, yet I can count the number of features I use regularly on my fingers. I can move around, search (always have to Google to remember how to replace). I know how to jump to ten lines down, but instead I find myself pressing and holding the down key to get to it instead.

I've just started i3. I love it. But I have one shortcut to open chromium and another to open a terminal. I find myself clicking instead of using the keys to switch focus between windows. There are so many other features in it that I could use.

I RTFM on quite a lot, but my issue isn't learning the knowledge, it's ingraining it into my workflow and making it become second nature.

Thoughts?

GNOME and Fedora

  • RFC: Integrating rsvg-rs into librsvg
    I have started an RFC to integrate rsvg-rs into librsvg. rsvg-rs is the Rust binding to librsvg. Like the gtk-rs bindings, it gets generated from a pre-built GIR file.
  • 1+ year of Fedora and GNOME hardware enablement
    A year and a couple of months ago, Christian Schaller asked me to pivot a little bit from working full time on Fleet Commander to manage a new team we were building to work on client hardware enablement for Fedora and GNOME with an emphasis on upstream. The idea was to fill the gap in the organization where nobody really owned the problem of bringing up new client hardware features vertically across the stack (from shell down to the kernel), or rather, ensure Fedora and GNOME both work great on modern laptops. Part of that deal was to take over the bootloader and start working closer to customers and hardware manufacturing parnters.
  • Fedora Atomic Workstation: Works on the beach
    My trip is getting really close, so I decided to upgrade my system to rawhide. Wait, what ? That is usually what everybody would tell you not to do. Rawhide has this reputation for frequent breakage, and who knows if my apps will work any given day. Not something you want to deal with while traveling.

Why You Shouldn’t Use Firefox Forks (and Proprietary Opera)

  • Why You Shouldn’t Use Firefox Forks Like Waterfox, Pale Moon, or Basilisk
    Mozilla Firefox is an open source project, so anyone can take its code, modify it, and release a new browser. That’s what Waterfox, Pale Moon, and Basilisk are—alternative browsers based on the Firefox code. But we recommend against using any of them.
  • Opera Says Its Next Opera Release Will Have the Fastest Ad Blocker on the Block
    Opera Software promoted today its upcoming Opera 52 web browser to the beta channel claiming that it has the faster ad blocker on the market compared to previous Opera release and Google Chrome. One of the key highlights of the Opera 52 release will be the improved performance of the built-in ad blocker as Opera claims to have enhanced the string matching algorithm of the ad blocker to make it open web pages that contain ads much faster than before, and, apparently than other web browsers, such as Chrome.

Graphics: Glxinfo, ANV, SPIR-V

  • Glxinfo Gets Updated With OpenGL 4.6 Support, More vRAM Reporting
    The glxinfo utility is handy for Linux users in checking on their OpenGL driver in use by their system and related information. But it's not often that glxinfo itself gets updated, except that changed today with the release of mesa-demos-8.4.0 as the package providing this information utility. Mesa-demos is the collection of glxinfo, eglinfo, glxgears, and utilities related to Mesa. With the Mesa-demos 8.4.0 it is predominantly glxinfo updates.
  • Intel ANV Getting VK_KHR_16bit_storage Support Wrapped Up
    Igalia's Jose Maria Casanova Crespo sent out a set of patches today for fixes that allow for the enabling of the VK_KHR_16bit_storage extension within Intel's ANV Vulkan driver. The patches are here for those interested in 16-bit storage support in Vulkan. This flips on the features for storageBuffer16BitAccess, uniformAndStorageBuffer16BitAccess, storagePushConstant16 and the VK_KHR_16bit_storage extension. This support is present for Intel "Gen 8" Broadwell graphics and newer. Hopefully the work will be landing in Mesa Git soon.
  • SPIR-V Support For Gallium3D's Clover Is Closer To Reality
    It's been a busy past week for open-source GPU compute with Intel opening up their new NEO OpenCL stack, Karol Herbst at Red Hat posting the latest on Nouveau NIR support for SPIR-V compute, and now longtime Nouveau contributor Pierre Moreau has presented his latest for SPIR-V Clover support. Pierre has been spending about the past year adding SPIR-V support to Gallium3D's "Clover" OpenCL state tracker. SPIR-V, of course, is the intermediate representation used now by OpenCL and Vulkan.

Security: Updates, Tinder, FUD and KPTI Meltdown Mitigation

  • Security updates for Friday
  • Tinder vulnerability let hackers [sic] take over accounts with just a phone number

    The attack worked by exploiting two separate vulnerabilities: one in Tinder and another in Facebook’s Account Kit system, which Tinder uses to manage logins. The Account Kit vulnerability exposed users’ access tokens (also called an “aks” token), making them accessible through a simple API request with an associated phone number.

  • PSA: Improperly Secured Linux Servers Targeted with Chaos Backdoor [Ed: Drama queen once again (second time in a week almost) compares compromised GNU/Linux boxes to "back doors"]

  • Another Potential Performance Optimization For KPTI Meltdown Mitigation
    Now that the dust is beginning to settle around the Meltdown and Spectre mitigation techniques on the major operating systems, in the weeks and months ahead we are likely to see more performance optimizations come to help offset the performance penalties incurred by mitigations like kernel page table isolation (KPTI) and Retpolines. This week a new patch series was published that may help with KPTI performance.
