  • Trip Report: C++ Standards Meeting in Rapperswil, June 2018

    A couple of weeks ago I attended a meeting of the ISO C++ Standards Committee (also known as WG21) in Rapperswil, Switzerland. This was the second committee meeting in 2018; you can find my reports on preceding meetings here (March 2018, Jacksonville) and here (November 2017, Albuquerque), and earlier ones linked from those. These reports, particularly the Jacksonville one, provide useful context for this post.

    At this meeting, the committee was focused full-steam on C++20, including advancing several significant features — such as Ranges, Modules, Coroutines, and Executors — for possible inclusion in C++20, with a secondary focus on in-flight Technical Specifications such as the Parallelism TS v2, and the Reflection TS.

  • Proposal for a staged RFC process

    I consider Rust’s RFC process one of our great accomplishments, but it’s no secret that it has a few flaws. At its best, the RFC offers an opportunity for collaborative design that is really exciting to be a part of. At its worst, it can devolve into bickering without any real motion towards consensus. If you’ve not done so already, I strongly recommend reading aturon’s excellent blog posts on this topic.

    The RFC process has also evolved somewhat organically over time. What began as “just open a pull request on GitHub” has moved into a process with a number of formal and informal stages (described below). I think it’s a good time for us to take a step back and see if we can refine those stages into something that works better for everyone.

    This blog post describes a proposal that arose over some discussions at the Mo

  • C gfx library for the Linux framebuffer with parallelism support

    FBGraphics was made to produce fullscreen pixels effects easily with non-accelerated framebuffer by leveraging multi-core processors, it is a bit like a software GPU (much less complex and featured!), the initial target platform is a Raspberry PI 3B and extend to the NanoPI (and many others embedded devices), the library should just work with many others devices with a Linux framebuffer altough there is at the moment some restrictions on the supported framebuffer format (24 bits).

  • Deterministic Firefox Builds

    As of Firefox 60, the build environment for official Firefox Linux builds switched from CentOS to Debian.

    As part of the transition, we overhauled how the build environment for Firefox is constructed. We now populate the environment from deterministic package snapshots and are much more stringent about dependencies and operations being deterministic and reproducible. The end result is that the build environment for Firefox is deterministic enough to enable Firefox itself to be built deterministically.

  • Brave Launches User Trials for Opt-In Ads That Reward Viewers

    We’ve been busy building our new Basic Attention Token (BAT) platform, which includes a new consent-based digital advertising model that benefits users, publishers, and advertisers. Our first phase started last Fall with the integration of BAT into Brave Payments, and enabled users to anonymously distribute contributions to their favorite publishers and creators.

  • Get Paid For Watching Ads: Brave Browser Announces Opt-in Trials

    Brave, the web browser which garnered a huge fan following, predominantly for its ad blocking feature, and depriving advertisers of confiscating private data by blocking trackers is in the news again. And this time, users can earn some cash.

    In a blog post, Brave announced that it will be conducting voluntary testing of their new ad model in which they will showcase at least 250 pre-packaged ads to users who will sign up for their early access version. Thus, offering a small amount of money in the form of micropayments.

    We built Mergify as a free service for open-source projects. The engine powering the service is also open-source.

  • Odd dependency on Google Chrome

    Hmm, so I noticed every time I started a fresh new Chrome, I logged into my Google account. So, once again clearing things I started Chrome, didn’t login and closed and reopened. I had Chrome running the second time! Alas, not with all the stuff synchronised.

    An issue for Mailspring put me onto the right path. installing gnome-keyring (or the dependencies p11-kit and gnome-keyring-pkcs11) fixed Chrome.

    So if Chrome starts but you get no window, especially if you use cinnamon, try that trick.

Instead of being blocked at every turn, though, Dorsey quickly discovered that the media streaming and smart home gadgets he used every day were vulnerable to varying degrees to DNS rebinding attacks. He could gather all sorts of data from them that he never would have expected.

  • Pros vs Joes CTF: The Evolution of Blue Teams

    Pros v Joes CTF is a CTF that holds a special place in my heart. Over the years, I’ve moved from playing in the 1st CTF as a day-of pickup player (signing up at the conference) to a Blue Team Pro, to core CTF staff. It’s been an exciting journey, and Red Teaming there is about the only role I haven’t held. (Which is somewhat ironic given that my day job is a red team lead.) As Blue teams have just formed, and I’m not currently attached to any single team, I wanted to share my thoughts on the evolution of Blue teaming in this unique CTF. In many ways, this will resemble the Blue Team player’s guide I wrote about 3 years ago, but will be based on the evolution of the game and of the industry itself. That post remains relevant, and I encourage you to read it as well.

  • Qt Contributor Summit 2018

    About two weeks ago i attended Qt Contributor Summit 2018, i did so wearing my KDAB hat, but given that KDE software is based heavily on Qt I think I'll give a quick summary of the most important topic that was handled at the Summit: Qt 6

  • The Qt 6 Plans For November 2020, Qt 5.15 Likely Being Last Of Qt5

    At the recent Qt Contributors' Summit as previously covered on Phoronix were some early discussions over plans to release Qt 6.0 in 2020. A few more tidbits of information have come to light on these interesting tool-kit plans.

    Albert Astals Cid of KDAB was at this recent Qt conference and he has now shared his summit notes, particularly around Qt 6. He confirms that Qt 6.0 is planning for a November 2020 release, Qt 6 should be an easy migration path from Qt 5, etc.

  • Google’s Fuchsia OS will support Linux apps

    Google’s non-Linux-based Fuchsia OS has added an emulator for running Debian Linux apps. Like its upcoming Linux emulator for Chrome OS, Fuchsia’s “Guest” app will offer tighter integration than typical emulators.

    Google has added a Guest app to its emergent and currently open source Fuchsia OS to enable Linux apps to run within Fuchsia as a virtual machine (VM). The Guest app makes use of a library called Machina that permits closer integration with the OS than is available with typical emulators, according to a recent 9to5Google story.

  • Here are the latest Chrome OS devices that will support Linux apps

    The ability to run Linux apps in virtual machines in Chrome is expanding beyond Google's flagship Pixelbook line of Chromebooks. The feature, for which plans were first discovered in late February, was formally announced by Google at I/O 2018. Unlike the existing solution, Crouton, support for Linux apps does not require enabling developer mode on Chrome OS, allowing users to install Linux apps without needing to sacrifice security protections.

    In addition to the Pixelbook, support for the new Crostini virtual machine feature has also come to the original Samsung Chromebook Plus, the detachable HP Chromebook X2, and the ASUS Chromebook Flip C101. Likewise, according to a report from xda-developers, the feature is coming to the Acer Chromebook Spin 13 and Chromebook 13, as well as 2018-era Chromeboxes, which all share the same board ID "fizz." Of these, the Acer Chromebox CX13 series and ASUS Chromebox 3 series both have multiple SKUs, maxing out with an Intel Core i7-8550U paired with 16GB RAM and 64GB storage for $750.

  • Linux App Support Is Coming To Acer Chromebook Flip C101

    Acer’s Chromebook Flip C101 is now officially the latest Chrome OS device expected to be in-line for virtualized Linux app support, following a new commit pushed to the Chromium Gerrit on June 15. That places the Flip C101 in a very select club alongside Google’s Pixelbook, the HP Chromebook x2, and the first generation Samsung Chromebook Plus. Of course, there’s no official date with regard to when Linux App support will arrive for the Chromebook Flip C101. If previous trends are followed, then it shouldn’t take too long at all for its official arrival in the Canary Channel of the OS. That comes following a commit indicating that support for the new feature has been moved from the Samsung Chromebook Plus to the devices’ shared parent board. Since only the Chromebook Plus and Chromebook Flip C101 share that board, dubbed “Gru,” that suggests that both devices will support Linux apps in a virtual environment.

Graphics: AMDGPU, Nvidia, Apple's Harm to Science

Graphics/Benchmarks
  • AMDGPU DRM Driver To Finally Expose GPU Load Via Sysfs

    The AMDGPU DRM driver appears to finally be crossing the milestone of exposing the current GPU load (as a percentage) in a manner that can be easily queried via sysfs.

    For years I've been frustrated via the lack of standardization of sysfs/debugfs files among the DRM drivers and some seemingly basic information not being exposed in such a manner that easily benefits various desktop plug-ins, those wanting to script basic monitors/checks/etc around such outputs, and use-cases like with the Phoronix Test Suite for easily querying this information too for its sensor recording. One of the frustrations with the Radeon Linux stack has been that there wasn't a trivial way to read the GPU load usage as a percentage... There's been ways if installing third-party utilities like RadeonTool, but no universal solution nor one that doesn't require root and would be widely available.

  • Radeon Software 18.20 Stable Released With Official Ubuntu 18.04 LTS Support

    The Radeon Software "AMDGPU-PRO" 18.20 hybrid driver stack is now available with official support for Ubuntu 18.04 LTS and Red Hat Enterprise Linux 17.20.

    Two months after the debut of the Ubuntu 18.04 LTS "Bionic Beaver" release, the Q2'2018 Radeon Sotware for Linux driver update has arrived with support for this latest long-term support release. Radeon Software 18.20 was officially released last week but seemingly went under everyone's radar until now.

  • Nvidia Releases a Batch of Open Source Tools for AI

    Graphics processors increasingly used as hardware accelerators for deep learning applications are also being deployed with the Kubernetes cluster orchestrator as another way to accelerate the scaling of training and inference for deep learning models.

    End of support for Apple’s OpenGL programming interface could pull the plug on molecular modelling software

    Researchers are voicing concerns over a move that may affect many 3D visualisation programs that are commonly used in computational research.

    Apple’s Macintosh operating systems (macOS) is set to end support for OpenGL, the programming interface frequently used to display 3D graphics in medical and scientific visualisation software, which has existed since 1992. Nearly all open source and commercial chemistry visualisation programs that are used to display atoms, molecules, bonds and protein ribbons – such as Mercury, VMD and PyMOL – use the system.

Microsoft and ICE, Major Downtimes Again

Filed under
Microsoft
  • Microsoft says pro-migrant, but no mention of cancelling ICE contract

    Both Microsoft chief executive Satya Nadella and president Brad Smith have responded to the Immigration and Customs Enforcement separating migrant children from their parents at the Mexico-US border by issuing strong statements against the practice.

    However, neither has said a word about ending the company's US$19.4 million contract with ICE.

    US President Donald Trump signed an executive order on Wednesday cancelling the separation policy for the next 20 days. About 4000 children have already been taken from their parents and there is no sign of their being returned.

    About 100 employees had sent a letter to Nadella, asking for the contract with ICE to be cancelled.

  • Microsoft CEO: don't worry, we're mostly helping the parts of ICE that don't involve kidnapping children

    As Microsoft employees grow increasingly furious that their employer is a key technology provider to ICE, providing, among other things, facial recognition software, the company is responding, conscious of the possibility of a repeat of Google's showdown with its employees over the provision of AI for drone warfare systems.

    Microsoft CEO Satya Nadella circulated an internal memo to all employees reassuring them that Microsoft only indirectly contributes to ICE's child kidnapping system by providing service to the rest of ICE.

    The child kidnapping crisis has prompted Mike Godwin to temporarily suspend Godwin's law, which allows me to point out that the service technicians IBM dispatched to service the Nazi tabulating machines only helped the Nazis to count the dead -- it wasn't like IBM was servicing gas chambers, just as Microsoft is only supplying adjacent services to an agency that the UN has condemned as "counter to human rights standards and principles."

  • Microsoft Azure suffers 11-hours of borkage across Europe

    The official word is that the downtime, which comes just days after Office 365 went titsup, lasted from around 5.45pm on Tuesday until 4.30am on Wednesday morning.

    However, many customers were still reporting issues today, despite Azure Support claiming that its engineers had "mitigated the issue in North Europe and impacted services should be recovered at this time".

  • A macOS Mojave Inspired GTK Theme Appears

    A new GTK theme brings the luscious look of macOS Mojave to the Linux desktop.

    Not that you should be surprised; we’ve written before about how easy it is to make Ubuntu look like a Mac.

    But thanks to this new macOS Mojave inspired GTK theme that fact is truer, and more faithful, than ever.

  • Make Ubuntu Look Like macOS Mojave’s Dark Mode

    If you’re a Linux user who likes the look of the dark mode coming in macOS Mojave, you’re in luck: there’s a GTK theme just for you.

    The theme is available on Gnome-Look.org alongside several other macOS inspired themes. You’re looking for the one titled McOS-MJV-Dark-mode, but feel free to download more if you think you might want to switch it up later.

    Installing is a little tricky: you need to create a .themes directory in your home folder, then extract the folder in the downloaded archive into that folder. Next you need to install Gnome Tweaks in the Ubuntu Software Store, which you can use to change the theme. You can also use Gnome Tweaks to move the buttons to the left side of the window, where they belong. Fight me.

    Arpit Joshipura, general manager of networking an orchestration for The Linux Foundation, says the latest Beijing release of the Open Networking Automation Platform (ONAP) contains several modules that have been ported to Kubernetes, with more to follow once the Casablanca release of ONAP is released.

  • A Platform Of A Certain Age And Respectability

    But seriously. The many rivals of the OS/400 platform and its follow-ons since that June 21, 1988, launch of the Application System/400 are now gone or not even on life support. We can all rattle them off, but the important ones that drove innovation for OS/400 and its children through to the current IBM i are DEC’s VMS for the VAX and Alpha systems, Hewlett Packard Enterprise’s MPE for the HP 3000 and HP-UX for the HP 9000s, and Sun Microsystems’ Solaris for the Sparc systems. You could throw in SCO Unix, Novell NetWare, and a slew of proprietary operating systems in Europe and Japan, and while you are at it, you should probably also include the IBM System/38’s CPF operating system and the IBM System/36’s SSP operating system. Even OS/2 and its PS/2 platform actually predate the AS/400 by 10 months – and they are long, long gone.

    The idea behind containers has been around since the 1970s, when the technology was first used to isolate application code on Unix systems. However, the use of containers only became widespread in 2013 with the advent of Docker, and container orchestration tools like Kubernetes are even newer than that.

A look at Lutris – Open Gaming Platform for GNU/Linux

Filed under

Gaming

Lutris is quite the handy application I’ve discovered, that helps with organization and installation of games on GNU/Linux, even if they come from multiple sources. One of the project's goals is to support any game that runs on Linux regardless of whether it runs natively, through Wine, or other means.

The main appeal of Lutris is that it provides an interface to manage all games installed on the machine regardless of source. While it is necessary to integrate the games in the application first, doing so is not super complicated. You may add local games right away by selecting them from the local system or visit the Lutris website to add games this way.

Lutris simplifies nearly everything. Users can visit the list of support games on the Lutris website, choose to download and install the game (Note: If its a game that must be bought, you must own it first.)

The website lists supported games and where you can acquire or download them. You can use filters on the site to display only free games, games of a genre, or use the built-in search to find games of interest quickly using it.

    The JSON support is in fact my favorite feature in Random Wallpaper. That's because thanks to it and the examples available on the Random Wallpaper GitHub Wiki, one can easily add Chromecast Images, NASA Picture of the day, Bing Picture of the day, and Google Earth View (Google Earth photos from a selection of around 1500 curated locations) as image sources.

8 reasons to use the Xfce Linux desktop environment

The Xfce desktop is thin and fast with an overall elegance that makes it easy to figure out how to do things. Its lightweight construction conserves both memory and CPU cycles. This makes it ideal for older hosts with few resources to spare for a desktop. However, Xfce is flexible and powerful enough to satisfy my needs as a power user. I've learned that changing to a new Linux desktop can take some work to configure it as I want—with all of my favorite application launchers on the panel, my preferred wallpaper, and much more. I have changed to new desktops or updates of old ones many times over the years. It takes some time and a bit of patience. I think of it like when I've moved cubicles or offices at work. Someone carries my stuff from the old office to the new one, and I connect my computer, unpack the boxes, and place their contents in appropriate locations in my new office. Moving into the Xfce desktop was the easiest move I have ever made. Read more

  • The life cycle of a software bug
    During the process of testing, bugs are reported to the development team. Quality assurance testers describe the bug in as much detail as possible, reporting on their system state, the processes they were undertaking, and how the bug manifested itself. Despite this, some bugs are never confirmed; they may be reported in testing but can never be reproduced in a controlled environment. In such cases they may not be resolved but are instead closed. It can be difficult to confirm a computer bug due to the wide array of platforms in use and the many different types of user behavior. Some bugs only occur intermittently or under very specific situations, and others may occur seemingly at random. Many people use and interact with open source software, and many bugs and issues may be non-repeatable or may not be adequately described. Still, because every user and developer also plays the role of quality assurance tester, at least in part, there is a good chance that bugs will be revealed.

The liboffload library has also confused some with LLVM's libomptarget library for OpenMP support that is in much better shape.
