  • Intel Comet Lake Processors To Feature Up To 10 Cores: Linux Support List

    With Intel set to release their next-gen Comet Lake processors, a leaked Linux support list has indicated that the forthcoming desktop processors might feature up to 10 cores.

    Intel will still rely on the 14nm manufacturing process, and the Comet Lake-S is speculated to be based on the Skylake micro-architecture. It will succeed the currently popular Intel Core i9-9900K processor which has 8 cores and 16 threads.

  • The KVM Changes Aren't Too Notable For Linux 5.1, But Many x86 Cleanups

    Paolo Bonzini submitted the Kernel-based Virtual Machine (KVM) changes for the Linux 5.1 kernel on Friday, much later in the cycle than normal. This isn't due to some big ticket features landing but rather "some ugly factors" in the form of tracking down some bugs and ended up dropping some premature optimizations. 

    So for Linux 5.1 the KVM virtualization work isn't the most exciting but there are some clean-ups for the ARM code, similar work on the S390 front, bug fixes and improvements to the POWER code, and "many, many cleanups" on the x86 front. Along with the many x86/x86_64 cleanups to the KVM code, a number of unnecessary MMU code optimizations were removed.

  • Krita 4.2.0: the First Painting Application to bring HDR Support to Windows

    We’re deep in bug fixing mode now, because in May we want to release the next major version of Krita: Krita 4.2.0. While there will be a host of new features, a plethora of bug fixes and performance improvements, one thing is unique: support for painting in HDR mode. Krita is the very first application, open source or proprietary, that offers this!

    So, today we release a preview version of Krita 4.2.0 with HDR support baked in, so you can give the new functionality a try!

    Of course, at this moment, only Windows 10 supports HDR monitors, and only with some very specific hardware. Your CPU and GPU need to be new enough, and you need to have a monitor that supports HDR. We know that the brave folks at Intel are working on HDR support for Linux, though!

  • When "Zoë" !== "Zoë". Or why you need to normalize Unicode strings

    It first hit me many years ago, when I was building an app (in Objective-C) that imported a list of people from an user’s address book and social media graph, and filtered out duplicates. In certain situations, I would see the same person added twice because the names wouldn’t compare as equal strings.

    In fact, while the two strings above look identical on screen, the way they’re represented on disk, the bytes saved in the file, are different. In the first “Zoë”, the ë character (e with umlaut) was represented a single Unicode code point, while in the second case it was in the decomposed form. If you’re dealing with Unicode strings in your application, you need to take into account that characters could be represented in multiple ways.

  • GPS D-Day is less than a month away


    On the other hand, maybe very worried indeed: after all, GPS wasn't used half as much then as it is today. Bill Malik, Trend Micro's vice president told Tom's Guide: "Ports load and unload containers automatically, using GPS to guide the cranes. Public-safety systems incorporate GPS systems, as do traffic-monitoring systems for bridges. Twenty years ago these links were primitive. Now they are embedded. So any impact now will be substantially greater."


    To be clear, this doesn't impact all GPS devices. Anything made in the past decade has got a longer fuse, using 13 bits for the week counter meaning a total of 8,192 weeks. That means your Apple Watch won't start misbehaving until 2137, when you'll be long dead (happy Monday!)


  • Bruce Schneier: It’s time for technologists to become lawmakers

    Bruce Schneier, a well-known security guru, called on technologists to become lawmakers and policy makers so countries can deal with issues such as the governance of artificial intelligence and cybersecurity.

    Schneier teaches at the Harvard Kennedy School of government, and he said the place is crawling with economists because they were able to answer many of the questions that arose in the 20th century. But in the 21st century, change is happening faster, and it’s driven by technology.

    “The future is coming,” Schneier said, speaking at the RSA security conference in San Francisco. “It’s coming faster than we think. And it’s coming faster than our existing policy tools can deal with. And the only way to fix this is to develop a new set of policy tools. With the help of the technologists, you understand the technologies.”

  • XHCI (USB 3.0+) issues have finally been resolved!

    Users have been facing issues with XHCI (USB 3 host controller) bus driver since quite some time now. Last month, Waddlesplash, a team member at Haiku, worked towards fixing the XHCI bus driver. Though few users contributed some small fixes, which helped the driver to boot Haiku within QEMU. But there were still few issues that caused device lockups such as USB mouse/keyboard stalls.

    The kernel related issues have been resolved now. Even the devices don’t lock up now and even the performance has been greatly improved to 120MB/s on some USB3 flash drives and XHCI chipsets.

    Users can now try the improved driver which is more efficient. The only remaining issue is a hard-stall on boot with certain USB3 flash drives on NEC/Renesas controllers. The work related to USB2 flash drives on USB3 ports and mounting the flash drives has finished.

  • ESP8266 Gets Its Game On With Open Source Engine

    Well, judging by software frameworks like the “Little Game Engine” created by [Igor], it looks like the ESP is expanding its reach into offline projects as well. While it might not turn the ESP8266 into a next-gen gaming powerhouse, we’ve got to admit that the demos shown off so far are pretty impressive. When paired with a couple of buttons and a TFT display such as the ILI9341, the ESP could make for a particularly pocket-friendly game system.

    The game engine that [Igor] has developed provides the programmer with a virtual screen resolution of 128×128, a background layer, and 32 sprites which offer built-in tricks like collision detection and rotation. All while running at a respectable 20 frames per second. This environment is ideal for the sort of 2D scrolling games that dominated the 8 and 16-bit era of gaming, and as seen in the video after the break, it can even pull off a fairly decent clone of “Flappy Bird”.

  • The Sad State of Logging Bugs for Apple

    This is where things get screwy depending on the component your bug lands in, since bug management is group dependent. Many groups will have only one or two QA people to do the initial screening of those large drop areas for bugs. QA engineers are sometimes instructed to screen bugs with a priority and “fix period” before passing them off to the engineer responsible for the code. This is terrible because many engineers will not look at bugs with a low priority. It is much better for the engineer who “owns the code” to look at a bug and determine the priority. The QA engineers will frequently get a huge back log of bugs to screen, and it can take weeks, or even months, for some bugs to get screened. Sometimes this leads to a mass screening of bugs, marking them all with a low priority. Bug originators have to notice this, and complain about it for the priority to get increased. Worse yet, some groups mass close bugs older than a year or so, and ask the originator to re-open the bug if the issue still exists. A lot of people don’t pay attention to bugs that need verification, and they simply become lost.

  • What I learned at the ONAP & OPNFV Event in Paris-Saclay

    The ONAP and OPNFV projects kicked off 2019 with a combined developer event at the Nokia Paris-Saclay facility in France earlier this year.  A few more than 200 developers from those combined communities came together to discuss their next respective releases, plan longer-range strategic priorities, and for the first time ever met together to explore further collaboration between the two groups.

    As always, I get energized by taking part in these discussions and planning sessions feeding off of the enthusiasm, and passion for excellence that everyone in these communities exude.  This event had approximately 150 sessions spread across four days as well as an OPNFV Plugfest and 2 demonstrations set up by our Nokia hosts. I want to thank Nokia for hosting this event.  They have always been an incredibly supportive participant in these communities and an outstanding Platinum member of the Linux Foundation Networking (LFN) fund.

  • Videos and Books in GNOME 3.32

  • Dirk Eddelbuettel: RcppArmadillo

    A minor RcppArmadillo bugfix release arrived on CRAN today. This version has two local changes. R 3.6.0 will bring a change in sample() (to correct a subtle bug for large samples) meaning many tests will fail, so in one unit test file we reset the generator to the old behaviour to ensure we match the (old) test expectation. We also backported a prompt upstream fix for an issue with drawing Wishart-distributed random numbers via Armadillo which was uncovered this week. I also just uploaded the Debian version.

    Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 559 other packages on CRAN.

  • More on Headerbars: Rebuttals

    People pointed out that you can drag on the UI controls, or use the hidden Alt-drag shortcut. Other people questioned how useful it is to drag windows around anyway, preferring to maximize everything or use window tiling keyboard shortcuts. I will address these responses:

    “Just drag on the controls in the headerbar”

    First of all, dragging controls to drag the window isn’t very intuitive. What other controls outside the headerbar allow you to move the window when dragging on them? Sure, you can learn it, but this isn’t the same as a good user interface that re-uses familiarity with existing elements rather than making you learn new modes.

    Second, you can’t drag the window by dragging on controls that themselves implement draggable behaviors–such as tab bars, comboboxes, pop-up menus, and sliders. So those controls can’t be put on the headerbar without reducing the drag area and violating the “you can drag the window by dragging on the controls” rule. In the original post, I gave an example of Firefox’s horrendous CSD that puts draggable tabs in the headerbar, reducing the drag area for the window itself to almost nothing. Ensuring draggability by only using controls that are not themselves draggable reduces developer flexibility compared to a traditional titlebar. It’s just not a problem if you have a separate titlebar.

  • Revisiting PEP 394

    With the uptake of Python 3 (and the imminent end of life for Python 2.7), there is a question of which version of Python a user should get when they type "python" at the command line or have it as part of a shebang ("#!") line in a script. Back in 2011, PEP 394 ("The 'python' Command on Unix-Like Systems") was created as an informational PEP that relayed the recommendations of the Python core developers to Linux distributions and others in a similar position about which version to point python to. Now, Petr Viktorin, one of the authors of the PEP, would like to revisit those recommendations, which is something that is suggested in the PEP itself.

    Viktorin is concerned that the recommendations essentially require a distribution to include Python 2 if it wants to install a "python", in addition to explicit "python2" and/or "python3" commands. The current recommendations are that, if there is a python, it should point to the same place as python2, and that scripts which are compatible with both Python 2 and Python 3 may continue to use python on their shebang lines. That effectively means a distribution with shiny new Python 3 scripts (which also support Python 2) needs to ship Python 2, which is not what some distributions want.

    The main issue is that some distributions are supported for ten or more years, but Python 2, in the form of Python 2.7, will reach its end of life on January 1, 2020—just ten months away. That leaves those distributions with some tough choices. They can either break with PEP 394 by making the version invoked by python configurable, for example. Or they have to ship scripts that could happily work on Python 2 with shebang lines that will invoke Python 3 (e.g. #!/usr/bin/python3).

  • RInside 0.2.15

    A new release 0.2.15 of RInside arrived on CRAN and in Debian today. This marks the first release in almost two years, and it brings some build enhancements. RInside provides a set of convenience classes which facilitate embedding of R inside of C++ applications and programs, using the classes and functions provided by Rcpp.

    RInside is stressing the CRAN system a little in that it triggers a number of NOTE and WARNING messages. Some of these are par for the course as we get close to R internals not all of which are “officially” in the API. My continued thanks to the CRAN team for supporting the package.

    It has (once again!) been nearly two years since the last release, and a number of nice extensions, build robustifications (mostly for Windows) and fixes had been submitted over this period—see below for the three key pull requests. There are no new user-facing changes.

    For about a year now I’ve had the occasional run-ins with “light” internet abuse and cyberbullying. There are a lot of resources around youth (and sometimes even college students) who are being cyberbullied, but not a lot for adults.

    I wanted to write a bit about my experiences. As I write this, I have had eight instances of being the recipient of abuse from threads on popular forum sites, emails, and blog posts.

  • State of the copyleft union

    The license-importance divide seems almost generational: the older generation cares about licenses, and the younger generation does not. Yet, the historical focus on licensing in FLOSS, while occasionally prone to pedantry to a degree only developers can love, stemmed from serious governance considerations regarding how community members interact.

    Copyleft was invented to solve the many problems of project governance, assuring the rights of users and creating equal footing for all contributors. The licensing infrastructure today also has increased in complexity, with proprietary relicensing business models, excessive use of CLAs, and tricky clauses on top of existing licenses.

  • RISC-V opens up processor design

    Today, if you want to build a high-performance computing device, you can almost certainly find all the software you need in a free and open form. The same is not true for the processor chips that run that free software — whatever you choose, a chunk of what you pay will go on proprietary hardware licences to Intel, ARM, or their friends.

    RISC-V, pronounced 'Risk-Five', is a new architecture that's available under open, free and non-restrictive licences. It has widespread industry support from chip and device makers, and is designed to be freely extensible and customisable to fit any market niche. To be a success, however, it has to perform technically as well as be economic to design for, verify and program. It has enthusiastic supporters, but it also has enormous competition that has been dug into the very heartland of IT for decades.

Forbes Says The Raspberry Pi Is Big Business

Not that it’s something the average Hackaday reader is unaware of, but the Raspberry Pi is a rather popular device. While we don’t have hard numbers to back it up (extra credit for anyone who wishes to crunch the numbers), it certainly seems a day doesn’t go by that there isn’t a Raspberry Pi story on the front page. But given that a small, cheap, relatively powerful, Linux computer was something the hacking community had dreamed of for years, it’s hardly surprising. [...] So where has the Pi been seen punching a clock? At Sony, for a start. The consumer electronics giant has been installing Pis in several of their factories to monitor various pieces of equipment. They record everything from temperature to vibration and send that to a centralized server using an in-house developed protocol. Some of the Pis are even equipped with cameras which feed into computer vision systems to keep an eye out for anything unusual. [Parmy] also describes how the Raspberry Pi is being used in Africa to monitor the level of trash inside of garbage bins and automatically dispatch a truck to come pick it up for collection. In Europe, they’re being used to monitor the health of fueling stations for hydrogen powered vehicles. All over the world, businesses are realizing they can build their own monitoring systems for as little as 1/10th the cost of turn-key systems; with managers occasionally paying for the diminutive Linux computers out of their own pocket.

  • Interested In FreeSync With The RADV Vulkan Driver? Testing Help Is Needed
    Since the long-awaited introduction of FreeSync support with the Linux 5.0 kernel, one of the missing elements has been this variable rate refresh support within the RADV Vulkan driver. When the FreeSync/VRR bits were merged into Linux 5.0, the RadeonSI Gallium3D support was quick to land for OpenGL games but RADV Vulkan support was not to be found. Of course, RADV is the unofficial Radeon open-source Vulkan driver not officially backed by AMD but is the more popular driver compared to their official AMDVLK driver or the official but closed driver in their Radeon Software PRO driver package (well, it's built from the same sources as AMDVLK but currently with their closed-source shader compiler rather than LLVM). So RADV support for FreeSync has been one of the features users have been quite curious about and eager to see.

9 Admirable Graphical File Managers

Being able to navigate your local filesystem is an important function of personal computing. File managers have come a long way since early directory editors like DIRED. While they aren’t cutting-edge technology, they are essential software to manage any computer. File management consists of creating, opening, renaming, moving / copying, deleting and searching for files. But file managers also frequently offer other functionality. In the field of desktop environments, there are two desktops that dominate the open source landscape: KDE and GNOME. They are smart, stable, and generally stay out of the way. These use the widget toolkits Qt and GTK respectively. And there are many excellent Qt and GTK file managers available. We covered the finest in our Qt File Managers Roundup and GTK File Managers Roundup. But with Linux, you’re never short of alternatives. There are many graphical non-Qt and non-Gtk file managers available. This article examines 9 such file managers. The quality is remarkably good. Read more
