Linux VR Headset

Filed under
Linux
Hardware

Since most VR Headsets support Windows platforms today, there are very few options for Linux users. Despite its support, many people have faced troubles setting up and running their Headsets on Linux. However, not anymore. The VR gaming experience is now getting better!

The all-new Xrdesktop is an open-source development that lets you work with various desktop environments like GNOME and KDE. Since this project is under progress right now, we can hope for more features like Steam, Valve and other platforms for gaming and Virtual Reality experience.

In addition, the Xrdesktop will also offer integration with Windows as well. Once completed, it will be a great step towards traditional Linux desktop environments. The program is available for installation in both packages for Ubuntu Linux and Arch Linux.

An Easy Fix for a Stupid Mistake

Filed under
MDV

I waited a long time for Mageia 7 and for OpenMandriva Lx 4. When both distros arrived, I was very happy.

But new distros bring changes, and sometimes it is not easy to adapt. Mageia 7 has been rock-solid: it is doing a great job in my laptop and both in my daughter's desktop and in mine. There is one thing, though. I have been avoiding a strange mesa update that wants to remove Steam.

OpenMandriva is also fantastic, but this new release provided options like rock, release, and rolling. When I first installed the distro, I chose rock because I was shying away from the rolling flavor. Eventually, I had to move to rolling because that was the only way in which I could manage to install Steam in both my laptop and desktop machines.

  • Clear Linux Is Being Used Within Some Automobiles

    Intel's speedy Clear Linux distribution could be running under the hood of your car.

    While we're fascinated by the performance of Intel's open-source Clear Linux distribution that it offers meaningful performance advantages over other distributions while still focused on security and offering a diverse package set, we often see it asked... who uses Clear Linux? Some argue that Clear Linux is just a toy or technology demo, but it's actually more.

    There's an exciting patch set to GNOME Shell and Mutter now pending for finally wiring up the full-screen unredirected display / full-screen bypass compositing for helping the performance of full-screen games in particular on Wayland.

    GNOME on X11 has long supported the full-screen compositing bypass so the window manager / compositor gets out of the way when running full-screen games/applications. That support under Wayland hasn't been in place and thus there is a performance hit for full-screen Wayland-native software. But now thanks to Red Hat's Jonas Ådahl, that infrastructure now appears to be ready.

    In addition to the work being led by DigitalOcean on core scheduling to make Hyper Threading safer in light of security vulnerabilities, IBM and Oracle engineers continue working on Kernel Address Space Isolation to help prevent data leaks during attacks.

    Complementing the "Core Scheduling" work, Kernel Address Space Isolation was also talked about at this week's Linux Plumbers Conference in Lisbon, Portugal. The address space isolation work for the kernel was RFC'ed a few months ago as a feature to prevent leaking sensitive data during attacks like L1 Terminal Fault and MDS. The focus on this Kernel ASI is for pairing with hypervisors like KVM as well as being a generic address space isolation framework.

  • The Linux Kernel Is Preparing To Enable 5-Level Paging By Default

    While Intel CPUs aren't shipping with 5-level paging support, they are expected to be soon and distribution kernels are preparing to enable the kernel's functionality for this feature to extend the addressable memory supported. With that, the mainline kernel is also looking at flipping on 5-level paging by default for its default kernel configuration.

    Intel's Linux developers have been working for several years on the 5-level paging support for increasing the virtual/physical address space for supporting large servers with vast amounts of RAM. The 5-level paging increases the virtual address space from 256 TiB to 128 PiB and the physical address space from 64 TiB to 4 PiB. Intel's 5-level paging works by extending the size of virtual addresses to 57 bits from 48 bits.

Releasing Slax 9.11.0

Filed under
Debian

New school year has started again and next version of Slax is here too Smile this time it is 9.11.0. This release includes all bug fixes and security updates from Debian 9.11 (code name Jessie), and adds a boot parameter to disable console blanking (console blanking is disabled by default).

You can get the newest version at the project's home page, there are options to purchase Slax on DVD or USB device, as well as links for free download.

Surprisingly for me we skipped 9.10, I am not sure why Smile

I also experimented with the newly released series of Debian 10 (code name Buster) and noticed several differences which need addressing, so Slax based on Debian 10 is in progress, but not ready yet. Considering my current workload and other circumstances, it will take some more time to get it ready, few weeks at least.

    The last week I was in Milan with my wife Aiswarya to attend Akademy 2019, the yearly event of the KDE community. Once again it was a great experience, with lots of interesting conferences and productive BoF sessions (“Birds of a Feather”, a common name for a project meeting during a conference).

    On Sunday, we presented our talk “GCompris in Kerala, part 2”. First, Aiswarya told some bits of Free-Software history in Kerala, gave examples of how GCompris is used there, and explained her work to localize the new version of GCompris in Malayalam (the language of this Indian state). Then I made a quick report of what happened in GCompris the last 2 years, and talked about the things to come for our next release.

  • Akademy was a blast!

    I attended my first ever Akademy! The event was held at the University of Milano-Bicocca in Milan, Italy this year. And the experience was splendid. During the 2 day conference, I had the opportunity to talk at the Student Showcase, where all of the SoC students presented their work to the community. There were about 8 students, and everyone gave a good briefing on their project.

    My project this summer was with Kdenlive, the open source non linear professional video editor. I proposed to revamp one of the frequently used tools in the editor, called the Titler tool, which is used to create title clips. Title clips are video clips that contain text and/or images that are composited or appended to your video (eg: subtitles). The problem with the titler tool as it is, is that it uses QGraphicsView to describe a title clip and QGraphicsView was deprecated since the release of Qt5. This obviously leads to problems - upstream bugs crawling affecting the functionality of the tool and an overall degradation in the ease of maintenance of the codebase. Moreover, adding new features to the existing code base was no easy task and therefore, a complete revamp was something in sights of the developer community in Kdenlive for a long time now. I proposed to rework on the backend for the period of GSoC replacing the use of XML with QML and use a new rendering backend with QQuickRenderControl, along with a new MLT module to handle the QML frames. I was able to cover most of the proposed work, I seek to continue working on it and finish evolving the titler tool.

Bison 3.4.2 released [stable]

Filed under
GNU

Bison 3.4.2 is a bug fix release of the 3.4 series.  It fixes a number of 
hard-to-find bugs, mostly discovered by fuzzing. 
In Bison 3.4 a particular focus was put on improving the diagnostics, which 
are now colored by default, and accurate with multibyte input.  Their format 
was also changed, and is now similar to GCC 9's diagnostics. 
Users of the default backend (yacc.c) can use the new %define variable 
api.header.include to avoid duplicating the content of the generated header 
in the generated parser.  There are two new examples installed, including a 
reentrant calculator which supports recursive calls to the parser and 
Flex-generated scanner. 
See below for more details. 
================================================================== 
Bison is a general-purpose parser generator that converts an annotated 
context-free grammar into a deterministic LR or generalized LR (GLR) parser 
employing LALR(1) parser tables.  Bison can also generate IELR(1) or 
canonical LR(1) parser tables.  Once you are proficient with Bison, you can 
use it to develop a wide range of language parsers, from those used in 
simple desk calculators to complex programming languages. 
Bison is upward compatible with Yacc: all properly-written Yacc grammars 
work with Bison with no change.  Anyone familiar with Yacc should be able to 
use Bison with little trouble.  You need to be fluent in C, C++ or Java 
programming in order to use Bison. 
Here is the GNU Bison home page: 
   https://gnu.org/software/bison/ 
================================================================== 
Here are the compressed sources: 
  https://ftp.gnu.org/gnu/bison/bison-3.4.2.tar.gz   (4.1MB) 
  https://ftp.gnu.org/gnu/bison/bison-3.4.2.tar.xz   (3.1MB) 
Here are the GPG detached signatures[*]: 
  https://ftp.gnu.org/gnu/bison/bison-3.4.2.tar.gz.sig 
  https://ftp.gnu.org/gnu/bison/bison-3.4.2.tar.xz.sig

[*] Use a .sig file to verify that the corresponding file (without the 
.sig suffix) is intact.  First, be sure to download both the .sig file 
and the corresponding tarball.  Then, run a command like this: 
  gpg --verify bison-3.4.2.tar.gz.sig 
If that command fails because you don't have the required public key, 
then run this command to import it: 
  gpg --keyserver keys.gnupg.net --recv-keys 0DDCAA3278D5264E 
and rerun the 'gpg --verify' command. 
This release was bootstrapped with the following tools: 
  Autoconf 2.69 
  Automake 1.16.1 
  Flex 2.6.4 
  Gettext 0.19.8.1 
  Gnulib v0.1-2844-g03add7eb9 
================================================================== 
NEWS 
* Noteworthy changes in release 3.4.2 (2019-09-08) [stable]

** Bug fixes

  In some cases, when warnings are disabled, bison could emit tons of white
  spaces as diagnostics.

  When running out of memory, bison could crash (found by fuzzing).

  When defining twice the EOF token, bison would crash.

  New warnings from recent compilers have been addressed in the generated
  parsers (yacc.c, glr.c, glr.cc).

  When lone carriage-return characters appeared in the input file,
  diagnostics could hang forever.

* Noteworthy changes in release 3.4.1 (2019-05-22) [stable]

** Bug fixes

  Portability fixes.

* Noteworthy changes in release 3.4 (2019-05-19) [stable]

** Deprecated features

  The %pure-parser directive is deprecated in favor of '%define api.pure'
  since Bison 2.3b (2008-05-27), but no warning was issued; there is one
  now.  Note that since Bison 2.7 you are strongly encouraged to use
  '%define api.pure full' instead of '%define api.pure'.

** New features

*** Colored diagnostics

  As an experimental feature, diagnostics are now colored, controlled by the
  new options --color and --style.

  To use them, install the libtextstyle library before configuring Bison.
  It is available from

    https://alpha.gnu.org/gnu/gettext/

  for instance

    https://alpha.gnu.org/gnu/gettext/libtextstyle-0.8.tar.gz

  The option --color supports the following arguments:
    - always, yes: Enable colors.
    - never, no: Disable colors.
    - auto, tty (default): Enable colors if the output device is a tty.

  To customize the styles, create a CSS file similar to

    /* bison-bw.css */
    .warning   { }
    .error     { font-weight: 800; text-decoration: underline; }
    .note      { }

  then invoke bison with --style=bison-bw.css, or set the BISON_STYLE
  environment variable to "bison-bw.css".

*** Disabling output

  When given -fsyntax-only, the diagnostics are reported, but no output is
  generated.

  The name of this option is somewhat misleading as bison does more than
  just checking the syntax: every stage is run (including checking for
  conflicts for instance), except the generation of the output files.

*** Include the generated header (yacc.c)

  Before, when --defines is used, bison generated a header, and pasted an
  exact copy of it into the generated parser implementation file.  If the
  header name is not "y.tab.h", it is now #included instead of being
  duplicated.

  To use an '#include' even if the header name is "y.tab.h" (which is what
  happens with --yacc, or when using the Autotools' ylwrap), define
  api.header.include to the exact argument to pass to #include.  For
  instance:

    %define api.header.include {"parse.h"}

  or

    %define api.header.include {}

*** api.location.type is now supported in C (yacc.c, glr.c)

  The %define variable api.location.type defines the name of the type to use
  for locations.  When defined, Bison no longer defines YYLTYPE.

  This can be used in programs with several parsers to factor their
  definition of locations: let one of them generate them, and the others
  just use them.

** Changes

*** Graphviz output

  In conformance with the recommendations of the Graphviz team, if %require
  "3.4" (or better) is specified, the option --graph generates a *.gv file
  by default, instead of *.dot.

*** Diagnostics overhaul

  Column numbers were wrong with multibyte characters, which would also
  result in skewed diagnostics with carets.  Beside, because we were
  indenting the quoted source with a single space, lines with tab characters
  were incorrectly underlined.

  To address these issues, and to be clearer, Bison now issues diagnostics
  as GCC9 does.  For instance it used to display (there's a tab before the
  opening brace):

    foo.y:3.37-38: error: $2 of ‘expr’ has no declared type
     expr: expr '+' "number"        { $$ = $1 + $2; }
                                         ^~
  It now reports

    foo.y:3.37-38: error: $2 of ‘expr’ has no declared type
        3 | expr: expr '+' "number" { $$ = $1 + $2; }
          |                                     ^~

  Other constructs now also have better locations, resulting in more precise
  diagnostics.

*** Fix-it hints for %empty

  Running Bison with -Wempty-rules and --update will remove incorrect %empty
  annotations, and add the missing ones.

*** Generated reports

  The format of the reports (parse.output) was improved for readability.

*** Better support for --no-line.

  When --no-line is used, the generated files are now cleaner: no lines are
  generated instead of empty lines.  Together with using api.header.include,
  that should help people saving the generated files into version control
  systems get smaller diffs.

** Documentation

  A new example in C shows an simple infix calculator with a hand-written
  scanner (examples/c/calc).

  A new example in C shows a reentrant parser (capable of recursive calls)
  built with Flex and Bison (examples/c/reccalc).

  There is a new section about the history of Yaccs and Bison.

** Bug fixes

  A few obscure bugs were fixed, including the second oldest (known) bug in
  Bison: it was there when Bison was entered in the RCS version control
  system, in December 1987.  See the NEWS of Bison 3.3 for the previous
  oldest bug.

If the tab is there, go to it and enable all enhancements, and click Apply. Next, disable them all, and click Apply again.

  • Lilocked ransomware (Lilu) affects thousands of Linux-based servers [Ed: This is not about "Linux"; they're repeating ZDNet (tabloid) talking points from their anti-Linux trolls, whom CBS hired to attack Linux (the real issue here is malware being installed)]

    A ransomware strain named Lilocked or Lilu has been affecting thousands of Linux-based servers all over the world since mid-July and the attacks got intensified by the end of August, ZDNet reports.

  • DigitalOcean Continues Working On Linux Core Scheduling To Make HT/SMT Safer

    With Hyper Threading continuing to look increasingly unsafe in data centers / shared computing environments in light of all the speculative execution vulnerabilities exposed thus far particularly with L1TF and MDS having no SMT-secure mitigation, DigitalOcean continues working on their Linux kernel "core scheduling" patches so they can still make use of HT/SMT in a sane and safe manner.

    DigitalOcean's core scheduling work is their way to make Hyper Threading safe by ensuring that only trusted applications run concurrently on siblings of a core. Their scheduler also tries to be smart about not using SMT/HT in areas where it could degrade performance.

Linux Kernel and Linux Foundation Leftovers

  • Improve memset
    
    since the merge window is closing in and y'all are on a conference, I
    thought I should take another stab at it. It being something which Ingo,
    Linus and Peter have suggested in the past at least once.
    
  • An Improved Linux MEMSET Is Being Tackled For Possibly Better Performance

    Borislav Petkov has taken to improve the Linux kernel's memset function with it being an area previously criticzed by Linus Torvalds and other prominent developers. Petkov this week published his initial patch for better optimizing the memset function that is used for filling memory with a constant byte.

  • Kernel Address Space Isolation Still Baking To Limit Data Leaks From Foreshadow & Co

    In addition to the work being led by DigitalOcean on core scheduling to make Hyper Threading safer in light of security vulnerabilities, IBM and Oracle engineers continue working on Kernel Address Space Isolation to help prevent data leaks during attacks. Complementing the "Core Scheduling" work, Kernel Address Space Isolation was also talked about at this week's Linux Plumbers Conference in Lisbon, Portugal. The address space isolation work for the kernel was RFC'ed a few months ago as a feature to prevent leaking sensitive data during attacks like L1 Terminal Fault and MDS. The focus on this Kernel ASI is for pairing with hypervisors like KVM as well as being a generic address space isolation framework.

  • The Linux Kernel Is Preparing To Enable 5-Level Paging By Default

    While Intel CPUs aren't shipping with 5-level paging support, they are expected to be soon and distribution kernels are preparing to enable the kernel's functionality for this feature to extend the addressable memory supported. With that, the mainline kernel is also looking at flipping on 5-level paging by default for its default kernel configuration. Intel's Linux developers have been working for several years on the 5-level paging support for increasing the virtual/physical address space for supporting large servers with vast amounts of RAM. The 5-level paging increases the virtual address space from 256 TiB to 128 PiB and the physical address space from 64 TiB to 4 PiB. Intel's 5-level paging works by extending the size of virtual addresses to 57 bits from 48 bits.

  • Research Shows Open Source Program Offices Improve Software Practices

    Using open source software is commonplace, with only a minority of companies preferring a proprietary-first software policy. Proponents of free and open source software (FOSS) have moved to the next phases of open source adoption, widening FOSS usage within the enterprise as well as gaining the “digital transformation” benefits associated with open source and cloud native best practices. Companies, as well as FOSS advocates, are determining the best ways to promote these business goals, while at the same time keeping alive the spirit and ethos of the non-commercial communities that have embodied the open source movement for years.

Releasing Slax 9.11.0

New school year has started again and next version of Slax is here too :) this time it is 9.11.0. This release includes all bug fixes and security updates from Debian 9.11 (code name Jessie), and adds a boot parameter to disable console blanking (console blanking is disabled by default). You can get the newest version at the project's home page, there are options to purchase Slax on DVD or USB device, as well as links for free download. Surprisingly for me we skipped 9.10, I am not sure why :) I also experimented with the newly released series of Debian 10 (code name Buster) and noticed several differences which need addressing, so Slax based on Debian 10 is in progress, but not ready yet. Considering my current workload and other circumstances, it will take some more time to get it ready, few weeks at least.

  • Back from Akademy 2019 in Milan

    The last week I was in Milan with my wife Aiswarya to attend Akademy 2019, the yearly event of the KDE community. Once again it was a great experience, with lots of interesting conferences and productive BoF sessions (“Birds of a Feather”, a common name for a project meeting during a conference). On Sunday, we presented our talk “GCompris in Kerala, part 2”. First, Aiswarya told some bits of Free-Software history in Kerala, gave examples of how GCompris is used there, and explained her work to localize the new version of GCompris in Malayalam (the language of this Indian state). Then I made a quick report of what happened in GCompris the last 2 years, and talked about the things to come for our next release.

  • Akademy was a blast!

    I attended my first ever Akademy! The event was held at the University of Milano-Bicocca in Milan, Italy this year. And the experience was splendid. During the 2 day conference, I had the opportunity to talk at the Student Showcase, where all of the SoC students presented their work to the community. There were about 8 students, and everyone gave a good briefing on their project. My project this summer was with Kdenlive, the open source non linear professional video editor. I proposed to revamp one of the frequently used tools in the editor, called the Titler tool, which is used to create title clips. Title clips are video clips that contain text and/or images that are composited or appended to your video (eg: subtitles). The problem with the titler tool as it is, is that it uses QGraphicsView to describe a title clip and QGraphicsView was deprecated since the release of Qt5. This obviously leads to problems - upstream bugs crawling affecting the functionality of the tool and an overall degradation in the ease of maintenance of the codebase. Moreover, adding new features to the existing code base was no easy task and therefore, a complete revamp was something in sights of the developer community in Kdenlive for a long time now. I proposed to rework on the backend for the period of GSoC replacing the use of XML with QML and use a new rendering backend with QQuickRenderControl, along with a new MLT module to handle the QML frames. I was able to cover most of the proposed work, I seek to continue working on it and finish evolving the titler tool.
