Ubuntu Expands Its Kernel Uploader Team

Filed under
Ubuntu

As a sign of the times with the Linux kernel being affected by an increasing number of CVEs (and particularly high profile ones at that), there are now more Ubuntu developers with upload rights for sending down new kernel upgrades.

Ubuntu's Kernel Uploaders Team approved adding Tyler Hicks (a longtime Canonical developer working as an Ubuntu kernel engineer) to the kernel uploaders group as well as Juerg Haefliger (having worked on stable kernels and recent high profile CVE issues already) and Khalid Elmously (another Canonical employee and existing kernel team member).

KDE: Summer with Kdenlive, Linux perf and KCachegrind, Qt at KDAB and Plasma 5.16 Beta

Filed under
KDE
  • This Summer with Kdenlive

    Hi! I’m Akhil K Gangadharan and I’ve been selected for GSoC this year with Kdenlive. My project is titled ‘Revamping the Titler Tool’ and my work for this summer aims to kickoff the complete revamp of one of the major tools used in video-editing in Kdenlive, called the Titler tool.

    [...]

    After the backend is done with, we begin integrating it with Kdenlive and evolve the titler to use the new backend.

    A great long challenge lies ahead, and I’m looking forward to this summer and beyond with the community to complete writing the tool - right from the backend to the new UI.

  • Linux perf and KCachegrind

    If you occassionally do performance profiling as I do, you probably know Valgrind's Callgrind and the related UI KCachegrind. While Callgrind is a pretty powerful tool, running it takes quite a while (not exactly fun to do with something as big as e.g. LibreOffice).

    Recently I finally gave Linux perf a try. Not quite sure why I didn't use it before, IIRC when I tried it somewhen long ago, it was probably difficult to set up or something. Using perf record has very little overhead, but I wasn't exactly thrilled by perf report. I mean, it's text UI, and it just gives a list of functions, so if I want to see anything close to a call graph, I have to manually expand one function, expand another function inside it, expand yet another function inside that, and so on. Not that it wouldn't work, but compared to just looking at what KCachegrind shows and seeing ...

    When figuring out how to use perf, while watching a talk from Milian Wolff, on one slide I noticed a mention of a Callgrind script. Of course I had to try it. It was a bit slow, but hey, I could finally look at perf results without feeling like that's an effort. Well, and then I improved the part of the script that was slow, so I guess I've just put the effort elsewhere Smile.

  • KDAB helps unu build Qt-based UI

    Those of you who’ve visited KDAB’s offices in Berlin, will know we have a fleet of electric scooters for our staff. You may have even tried one yourself!

    Today, unu, the Berlin-based mobility company that makes them, launches their latest electric scooter – the unu Scooter.

    The unu Scooter has been completely redeveloped, is more open to sharing and rental services and has the fastest acceleration you’ll find in any electric scooter, courtesy of its Bosch engine.

  • Help Test Plasma 5.16 Beta

    Plasma 5.16 beta was released last week and there?s now a further couple of weeks to test it to find and fix all the beasties. To help out download the Neon Testing image and install it in a virtual machine or on your raw hardware. You probably want to do a full-upgrade to make sure you have the latest builds. Then try out the new notifications system, or the new animated wallpaper settings or anything else mentioned in the release announcement. When you find a problem report it on bugs.kde.org and/or chat on the Plasma Matrix room. Thanks for your help!

Huawei and other mobile “tech giants”: you should (really) break free from Google/Android

Filed under
OS
Android
Google

Huawei has probably played a questionable game with user data and corporate data. This has led governments to discourage the usage of Huawei devices, which is a fair and understandable attitude.

However, what Huawei really didn’t understand is that their dependency on Google/Android technology and services would put them into this terrible situation. Discussions have moved out beyond regular commercial and trade arguments, and are now clearly out of control.

They should have learned from the past: USA has a significant track record when it comes to embargoes and export restrictions. They don’t even hesitate to force their allies to apply the same restrictions, by threatening them more or less directly, commercially and financially.

For Huawei, what we witness today is the result of 10 years of strategic blindness. They should have realized that when they sell a smartphone, most of the value is in the software, not in the hardware. Therefore, they shouldn’t have become so reliant on Google/Android for the software: this hard dependency is a major risk for any mobile business.

    Super Powered Battle Friends from Cache Grab Studios is a new platform fighter, with both local and online play and it's now in Early Access. As promised on the rather unsuccessful Kickstarter campaign, it was release with same-day Linux support.

  • Geneshift gets a GTA2-inspired update with civilians, an expanded demo, better maps for driving and more

    Geneshift continues to evolve into a very interesting top-down action game, mixing in a single-player/co-op campaign, various traditional multiple modes and a Battle Royale.

    The developer, Nik Nak Studios, said they're celebrating ten years since Geneshift first came online (originally under other names). This latest update pulls in some inspiration from GTA2, adding in roaming civilians you can take down which will eventually become aggressive towards you. The more you kill, the higher their aggression rating and loot dropping will be giving the various online modes like Deathmatch and Battle Royale a little mini-game.

  • Video recording and livestreaming software OBS Studio has a new 23.2 Release Candidate out

    For those who create videos and livestreams, OBS Studio is for the most part all you need. It continues advancing too, with a Release Candidate out for OBS 23.2.

    New features this time around include a hotkey to toggle the preview, the ability to preview scene transitions, the ability to estimate recording time available based on disk space (not that I've seen it, might be Windows only), a "luma" key video filter, the ability to copy and paste filter to/from scenes in addition to sources, the ability to centre items vertically or horizontally in the transform menus, a message when there's no sources included in a scene to help new users and numerous other enhancements.

  • DASH, the fast-paced platformer where you create the levels is launching in June with a new trailer

    But when Google launches the next version of Android later this year, it may not be available on Huawei devices.

    Future Huawei devices may no longer have apps such as YouTube and Maps.

  • Forget Huawei, The Internet Of Things Is The Real Security Threat

    We've noted for a while how a lot of the US protectionist security hysteria surrounding Huawei isn't supported by much in the way of hard data. And while it's certainly possible that Huawei helps the Chinese government spy, the reality is that Chinese (or any other) intelligence services don't really need to rely on Huawei to spy on the American public. Why? Because people around the world keep connecting millions of internet of broken things devices to their home and business networks that lack even the most rudimentary of security and privacy protections.

    Week after week we've documented how these devices are being built with both privacy and security as a distant afterthought, resulting in everything from your television to your refrigerator creating both new attack vectors and wonderful new surveillance opportunities for hackers and state actors.

A Look At The MDS Cost On Xeon, EPYC & Xeon Total Impact Of Affected CPU Vulnerabilities

Filed under
Graphics/Benchmarks

This weekend I posted a number of benchmarks looking at the performance impact of the new MDS/Zombieload vulnerabilities that also included a look at the overall cost of Spectre/Meltdown/L1TF/MDS on Intel desktop CPUs and AMD CPUs (Spectre). In this article are similar benchmarks but turning the attention now to Intel Xeon hardware and also comparing those total mitigation costs against AMD EPYC with its Spectre mitigations.

This article offers a look at the MDS/Zombieload mitigations on a 1st Gen Skylake Xeon Scalable server as well as a Kabylake Xeon E3 server for reference. Following that is a look at the total CPU vulnerability mitigation costs for 1st Gen Xeon Scalable, 2nd Gen Xeon Scalable (Cascade Lake), and an AMD EPYC 2P server as well for its Spectre mitigations.

As expected given Intel's guidance last week of their latest Xeon processors being mitigated for MDS, indeed, the dual Xeon Platinum 8280 Cascade Lake server reported it was not affected by the MDS mitigations and thus not enabled. So for the MDS tests up first it's just some reference results using a dual Xeon Gold 6138 Skylake server running Ubuntu 19.04 with the Linux 5.0 patched kernel and reference results side-by-side for a separate Xeon E3-1275 v6 server.

The Two Solitudes of GNOME and KDE

Filed under
KDE
GNOME

Novelist Hugh MacLennan once described Canada as “two solitudes” — an English-speaking one and a French-speaking one, neither of which had much to do with the other. The description is decades out-dated, and today a dozen solitudes might be more accurate. However, the phrase echoes in my mind whenever I think of the gulf today between GNOME technologies and KDE software compilations. Although both are based on the Linux kernel, the expectations and philosophies are different enough that they might almost be different operating systems.

The difference has not always existed. When GNOME and KDE began in the late 1990s, both were scrambling hard to match desktops on other operating systems. Widgets aside, the differences were minimal. For years the two graphical interfaces regularly traded places on reader surveys, with perhaps a slight edge for GNOME, depending on the magazine or site conducting the survey. Flame wars could be fierce, but like many flame wars, the fierceness reflected how trivial the differences mostly were — at least, after KDE’s Qt toolkit became free software. The difference was largely one of branding.

Still, GNOME and KDE each slowly developed its own ecosystem of applications. A few applications like OpenOffice.org were shared, presumably because developing alternative for large applications was difficult. Moreover, the popularity of some apps like Firefox overwhelmed native alternatives like KDE’s Konqueror. But in categories like music-players, archivers, and CD burners, each slowly started to developed its own set of tools.

  • Health Port: Creates Holistic Solution for Open Source Electronic Health Records

    The medical industry has been slow to embrace modern record-keeping technology. Health Port is bringing next-generation blockchain technology to Electronic Health Records (EHR). The idea behind Health Port is simple; make EHR technology simple, safe, and open source.

    Around the time that the internet bubble was in full swing, there is a good chance that your local doctors were still writing health care records by hand. The internet has been a big force in the world of data, but the medical industry has been left out of the internet data revolution.

    [...]

    The most important reason why EHRs need to be open is patient care. A person should have easy access to their medical history. When a person changes location or healthcare providers, making sure their medical records go with them shouldn’t be a hassle.

    An EHR isn’t special from a data handling perspective. Much like other sensitive personal information, it should be easy to share with authorized agents. In an emergency care scenario, this aspect of EHRs is even more important.

  • Intel Loses 5X More Average Performance Than AMD From Mitigations: Report

    Intel has published its own set of benchmark results for the mitigations to the latest round of vulnerabilities, but Phoronix, a publication that focuses on Linux-related news and reviews, has conducted its own testing and found a significant impact. Phoronix's recent testing of all mitigations in Linux found the fixes reduce Intel's performance by 16% (on average) with Hyper-Threading enabled, while AMD only suffers a 3% average loss. Phoronix derived these percentages from the geometric mean of test results from its entire test suite.

    From a performance perspective, the overhead of the mitigations narrow the gap between Intel and AMD's processors. Intel's chips can suffer even more with Hyper-Threading (HT) disabled, a measure that some companies (such as Apple and Google) say is the only way to make Intel processors completely safe from the latest vulnerabilities. In some of Phoronix's testing, disabling HT reduced performance almost 50%. The difference was not that great in many cases, but the gap did widen in almost every test by at least a few points.

    A few months ago, we received a phone call from a bioinformatics group at a European university. The problem they were having appeared very simple. They wanted to know how to usemmap() to be able to load a large data set into RAM at once. OK I thought, no problem, I can handle that one. Turns out this has grown into a complex and interesting exercise in profiling and threading. The background is that they are performing Markov-Chain Monte Carlo simulations by sampling at random from data sets containing SNP (pronounced “snips”) genetic markers for a selection of people. It boils down to a large 2D matrix of floats where each column corresponds to an SNP and each row to a person. They provided some small and medium sized data sets for me to test with, but their full data set consists of 500,000 people with 38 million SNP genetic markers!
  • Why precompiled headers do (not) improve C++ compile times
    Would you like your C++ code to compile twice as fast (or more)? Yeah, so would I. Who wouldn't. C++ is notorious for taking its sweet time to get compiled. I never really cared about PCHs when I worked on KDE, I think I might have tried them once for something and it didn't seem to do a thing. In 2012, while working on LibreOffice, I noticed its build system used to have PCH support, but it had been nuked, with the usual poor OOo/LO style of a commit message stating the obvious (what) without bothering to state the useful (why). For whatever reason, that caught my attention, reportedly PCHs saved a lot of build time with MSVC, so I tried it and it did. And me having brought the PCH support back from the graveyard means that e.g. the Calc module does not take 5:30m to build on a (very) powerful machine, but only 1:45m. That's only one third of the time. In line with my previous experience, on Linux that did nothing. I made the build system support also PCH with GCC and Clang, because it was there and it was simple to support it too, but there was no point. I don't think anybody has ever used that for real. Then, about a year ago, I happened to be working on a relatively small C++ project that used some kind of an obscure build system called Premake I had never heard of before. While fixing something in it I noticed it also had PCH support, so guess what, I of course enabled it for the project. It again made the project build faster on Windows. And, on Linux, it did too. Color me surprised.
