News briefs for March 18, 2019.

Khronos today released the OpenXR 0.90 provision specification. From the
press release: “OpenXR is a unifying, royalty-free, open standard that
provides high-performance access to augmented reality (AR) and virtual
reality (VR)—collectively known as XR—platforms and devices. The new
specification can be found on the Khronos website and is released in
provisional form to enable developers and implementers to provide feedback at
the OpenXR forum.” And following the release of the OpenXR 0.09 provision specification, Collabora announced Monado: “at the center of Monado is a fully open source OpenXR runtime for Linux. It is the component in the XR software stack that implements the hardware support, it knows how to process non standard input from HMD devices and controllers, it knows how to render to those devices and it provides this functionality via the standard OpenXR API.”

Solus 4 Fortitude
is now available
. This new major release “delivers a
brand new Budgie experience, updated sets of default applications and
theming, and hardware enablement”. Visit the download page to install.

3.32 was released
yesterday. This is a feature release of the GNOME email
application and aims to “align Geary’s interface better with GNOME 3.32”. It
has “a new icon, the application menu has been moved to a burger menu in the
main window, sender images in conversations are now taken from the the
desktop address-book, and those without a custom photo are given a
personalised image with initials and background colour based on their name”,
along with the usual bug fixes and other improvements. To install, visit here.

Linux kernel 5.1-rc1 is out. Linus Torvalds writes,
“The merge window felt fairly normal to me. And looking at the stats,
nothing really odd stands out either. It’s a regular sized release
(which obviously means “big” – , but it’s not bigger than usual) and
the bulk of it (just over 60%) is drivers. All kinds of drivers, the
one that stands out for being different is the habanalabs AI
accelerator chip driver, but I suspect we’ll be starting to see more
of that kind of stuff. But there are all the usual suspects too – gpu,
networking, block devices etc etc.”

recently announced that Opera 60 has entered the beta stream
“Opera 60 beta brings a refreshed interface with light and dark
themes inspired by high- and low-key lighting photography, respectively. It
will also include a Crypto Wallet in the sidebar.” This version is actually merging
with Opera 59, and the two versions are being called Reborn 3,
which will be in the stable channel soon. See the Opera 60
for more
details on the changes.

Have a look at the game below, after White has played his 15th move. A similar position to this occurred at Street Chess on Saturday, and at first glance I just assumed White had a big advantage. (NB I cannot recall which White rook was on d1, so White’s 14th move may have been Raxd1). With the bishop well posted on f3, and being the first to get to the d file, all I could see was White using the initiative to win the game (and in the game on Saturday, this is what happened).
So I am a little surprised that Black won the game given here. Of course the black pieces were being handled by GM Gawain Jones, and he did out rate his opponent by a significant amount, but White should at least hold this. Playing though the game a few times (with the engine off) I suspect that White was a little eager to swap pieces off (especially the bishops), until it reached a point (on move 31) when the final rook exchange left White with a lost pawn ending.
If there is a lesson to be had here, maybe it is that if you look like you have an advantage, keep the pieces that give you the advantage!
