  • Proton 3.7 Updated, More RADV Fixes To Help Steam Play Gaming

    Overnight Valve promoted their Proton 3.7-7 build with better alt-tab handling and full-screen behavior for many games. There is also fixed mouse behavior and DXVK 0.80 is now used for the Direct3D-11-over-Vulkan translation to yield better Steam Play gaming performance.

    Steam Play 3.7-8 is also now available in beta with minor compatibility fixes, which Valve says is in preparation for future Proton versions.

  • AMD Stages A Number Of Fixes Ahead Of Linux 4.20~5.0 - Plus Vega 20 "MGPU Fan Boost"

    Following several interesting and exciting feature pull requests for the next Linux kernel (to be released as either version 4.20 or 5.0), AMD developers have moved onto stabilizing this massive amount of new feature code.

    The first "fixes" pull request was submitted today to DRM-Next focusing on stabilizing and fixing issues stemming from all this new code. As a reminder, that feature code ranges from AMD Picasso APU support along with Raven 2, a lot of Vega 20 enablement code including compute support, initial xGMI support, VCN dynamic power gating, DC display code enhancements, VCN JPEG engine support, Raven Ridge GFXOFF support, GPUVM virtual memory performance improvements, and a variety of other interesting work.

  • NVIDIA's Guide For Getting Started With RTX Ray-Tracing In Vulkan

    Last month's Vulkan 1.1.85 release brought NVIDIA's experimental ray-tracing extension (VK_NVX_raytracing) while for those curious how this fits into the Vulkan workflow, NVIDIA today published a guide for getting started with ray-time ray-tracing in the Vulkan space.

  • Freedesktop.org: its past and its future

    At the 2018 X.Org Developers Conference (XDC) in A Coruña, Spain, Daniel Stone gave an update on the status of freedesktop.org, which serves multiple projects as a hosting site for code, mailing lists, specifications, and more. As its name would imply, it started out with a focus on free desktops and cross-desktop interoperability, but it lost that focus—along with its focus in general—along the way. He recapped the journey of fd.o (as it is often known) and unveiled some idea of where it may be headed in the future.

    The talk was billed with Keith Packard as co-presenter, but Packard could not make it to XDC; Stone said that he sent Packard a copy of the slides and heard no complaints, so he left Packard on the slide deck [PDF]. Stone wanted to start with the history of fd.o, because there are lots of new contributors these days—"which is great"—who may not know about it.

ps_mem Shows Per-Program Memory Usage On Linux

Unlike many other tools that report memory usage per process, ps_mem reports the RAM usage of programs. For example it shows how much RAM is used by all Chromium processes combined. The program developer notes that the ps_mem name is used for backwards compatibility, but a more accurate name would be coremem. The displayed RAM is calculated by adding the sum of private RAM and the sum of shared RAM for a program processes. Running ps_mem with no arguments shows a list programs and their RAM usage in ascendant order (from the lowest RAM usage to the highest). For each program it shows the private, shared, and total used RAM, as well as the number of processes. Swap information for each program can be shown as well, by using the -S option (sudo ps_mem -S).

  • The State of Neural Machine Translation for Asian Languages
    Open source for Asian language NLP is getting more and more active, but it would be useful to have more projects that are both frequently updated and popular. Sometimes, code licensing plays a negative role, because many old projects are GPL (General Public License). Jieba, Rakuten MA, KoNLPy are some frequently-used libraries for CJK (Chinese-Japanese-Korean) NLP. (Lucy Park is a KoNLPy developer.)
  • Will your organization change itself to death?
    Organizations, open or otherwise, cannot spend every moment changing themselves. For one thing, doing so would mean abandoning whatever mission they purport to have. As the saying goes, "if you don't stand for something, you'll fall for anything." That adage, while most common in the context of political beliefs, is applicable here too.
  • Open source may be the future, but very few are writing it

    Open source may dominate the software we use to power the cloud, AI, and more, but a small percentage of developers do most of the coding. While it has long been true that for any given open source project, the vast majority of core contributions come from a cabal of committed developers, it seemed like the popularity of using open source would bleed into writing open source. Nope.

  • viewport and iphone reflow

    Something that’s annoyed me for some years is that all the web sites I build don’t work quite right with my iphone. Scroll down a page, visit a link, go back, and safari jumps back to the top of the page. Very annoying. Pretty much no other site I visit seems to have this problem, yet I couldn’t figure out what I was doing wrong since I’m barely doing anything at all. There are some support forum complaints about similar bugs, but mostly from several years ago, and mostly “solved: it works now” without explanation.

    Finally, figured out what seems to be the problem. The iphone introduces its own viewport meta tag, to define the screen dimensions, and control whether the user can zoom or not. A lot of sites abuse this to the point of unusability, so I very determinedly stayed clear. But without a viewport tag, safari is really dumb.

  • Categorizing OpenBSD Bugs

    I thought it would be interesting to see if something similar were true of OpenBSD bugs. I went through two years of OpenBSD errata for the most recent four releases (6.1, 6.2, 6.3 and 6.4) and categorized each bug.

  • Bug in French government’s WhatsApp replacement let anyone join Élysée chats

    Tchap is not intended to be a classified communications system—it runs on regular Android phones and uses the public Internet. But as the DINSIC, the French inter-ministry directorate for information systems that runs Tchap put it, Tchap "is an instant messenger allowing government employees to exchange real-time information on everyday professional issues, ensuring that the conversations remain hosted on the national territory." In other words, it's to keep official government business off of Facebook's and Telegram's servers outside France.

    Based on the Riot.im chat application from the open source project Matrix, Tchap is officially still in "beta," according to DINSIC. And that beta test is getting off to a rough start. Within two days, French security researcher Baptiste Robert—who goes by the Twitter handle @fs0c131y (aka Elliot Alderson)—had tapped into Tchap and subsequently viewed all of the internal "public" discussion channels hosted by the service.
