You Don't Need To Ask

Alan Pope reminds us that Ubuntu has been around for seventeen years now and mentions it has changed during that time. Alan fears some potential contributors are being missed for fear of asking permission to get involved, thus reminding us that we should be as encouraging to newcomers as we can be.

Ubuntu Voltage

Alan Pope reminds us that for a few years there has been a live version of Ubuntu Podcast seen at FOSS Talk Live, which is going to happen again at FOSS Talk Live 2021 on Saturday 12 June. Time has yet to be decided, but we are reminded of some prior years, with a video link provided for FOSS Talk Live 2019.

Updated Snaps for KDE Apps

Jonathan Riddell tells us he has updated the kblocks, labplot and okular KDE snaps, and asks for some testing of them. We are given details on how to contact Jonathan via Matrix.

Hirsute Yaru Call for Testing

Alan Pope advises that release 21.04 enters User Interface Freeze on March 18th! Alan provides a list of the changes in the Yaru theme and pronounces "it needs testing by a wider audience". Links and directions are given to install the new image and the GitHub theme. As well is the link to the Yaru team GitHub issue tracker to report any issues.

Other Community News

Alexander's fix was accepted and merged into 5.11-rc7 and backported to stable trees. Links to the relevant Ubuntu CVE are provided.

In the Blogosphere

Canonical Chooses Google’s Flutter UI SDK to Build Future Ubuntu Apps

Marius Nestor reminds us what Flutter is, and then tells us that Canonical has announced they will use the Flutter UI framework for their own Ubuntu apps. Marius quotes Canonical's Ken VanDine, who gave a talk on 3 March 2021 at Google's Flutter Engage event, with embedded video provided.

Looks Like Ubuntu 21.04 Will Offer a Hybrid GNOME 3.38 Desktop with GNOME 40 Apps

Marius Nestor gives the opinion that Ubuntu 21.04 will likely come with some GNOME 40 desktop apps on the hybrid GNOME 3.38-based desktop. Marius provides a list of the GNOME 40 apps: those currently found in installed Ubuntu hirsute systems, other GNOME 40 stack applications available in the repositories but not automatically included, those that haven't received any updates (yet) for GNOME 40, plus those not available. Marius' conclusion is Ubuntu 21.04 offers a more modern experience due to these inclusions.

Google and Debian work together to make COVID-19 researchers' lives easier

A Bazel Blog update tells us that it is easy to install a package distributed for Debian and Ubuntu, that delivers "Tensorflow Machine Learning functionality for COVID-19 researchers". The package is needed to support the medical community to help with the COVID-19 pandemic in getting better tools to the medical professionals. We are given a brief history of how this happened, and with the joint effort of Debian and Google, the work will continue.
