GCompris releases version 1.0 to celebrate 20 years
The GCompris project,
which provides a "high quality educational software suite, including
a large number of activities for children aged 2 to 10", has announced its 1.0
release, which celebrates the 20th anniversary of the project. It
includes more than 100 activities, a new Dataset selection in the Activity
Settings menu for more than 50 activities, and four new activities,
including an Analog Electricity activity to simulate and learn about circuits.
KDE.news covered
the release: "We have built the activities to follow the
principles of 'nothing succeeds like success' and that children, when
learning, should be challenged, but not made to feel threatened. Thus,
GCompris congratulates, but does not reprimand; all the characters the
child interacts with are friendly and supportive; activities are brightly
colored, contain encouraging voices and play upbeat, but soothing music.
The hardware requirements for running GCompris are extremely low and it
will run fine on older computers or low-powered machines, like the
Raspberry Pi. This saves you and your school from having to invest in new
and expensive equipment and it is also eco-friendly, as it reduces the
amount of technological waste that is produced when you have to renew
computers to adapt to more and more power-hungry software. GCompris works
on Windows, Android and GNU/Linux computers, and on desktop machines,
laptops, tablets and phones." | | 1:13a |
Paalanen: Developing Wayland Color Management and High Dynamic Range Over on the Collabora blog, Pekka Paalanen writesabout adding color management and high dynamic range (HDR) support to the Wayland display server protocol. X11 already has support for color management tools and workflow, but not HDR, and Wayland currently doesn't support either, but Paalanen and others are working to change that. " As color management is all about color spaces and
gamuts, and high dynamic range (HDR) is also very much about color spaces
and gamuts plus extended luminance range, Sebastian [Wick] and I decided that
Wayland color management extension should cater for both from the
beginning. Combining traditional color management and HDR is a fairly new
thing as far as I know, and I'm not sure we have much prior art to base
upon, so this is an interesting research journey as well. There is a lot of
prior art on HDR and color management separately, but they tend to have
fundamental differences that makes the combination not obvious." | | 2:06p |

[$] epoll_pwait2(), close_range(), and encoded I/O
The various system calls and other APIs that the kernel provides for access
to files and filesystems has grown increasingly comprehensive over the
years. That does not mean, though, that there is no need or room for
improvement. Several relatively small additions to the kernel's
filesystem-related API are under consideration in the development
community; read on for a survey of some of this work. |
