Fedora Silverblue is an amazing immutable desktop Submitted by Roy Schestowitz on Sunday 12th of April 2020 12:42:18 AM Filed under Red Hat I recently switched my regular Fedora 31 workstation over to the 31 Silverblue release.I’ve played with Project Atomic before and have been meaning to try it out more seriously for a while, but never had the time.Silverblue provided the catalyst to do that.
What this brings to the table is quite amazing and seriously impressive.The base OS is immutable and everyone’s install is identical.This means quality can be improved as there are less combinations and it’s easier to test.
Upgrades to the next major version of Fedora are fast and secure.Instead of updating thousands of RPMs in-place, the new image is downloaded and the system reboots into it.
As the underlying images don’t change, it also offers full rollback support.
This is similar to how platforms like Chrome OS and Android work, but thanks to ostree it’s now available for Linux desktops! That is pretty neat.
It doesn’t come with a standard package manager like dnf.Instead, any packages or changes you need to perform on the base OS are done using rpm-ostree command, which actually layers them on top.
And while technically you can install anything using rpm-ostree, ideally this should be avoided as much as possible (some low level apps like shells and libvirt may require it, though).Flatpak apps and containers are the standard way to consume packages.As these are kept separate from the base OS, it also helps improve stability and reliability.» Anodyne developer makes the game open-source
Anodyne hit the Switch back in 2019, but now players can see the game in a whole knew way.The developer behind the title has made the entire project open-source, which means you can dig into every nook and cranny to see what’s hiding inside.The developer is hoping that by bringing the game’s source code, art, level editor, and music to Github, players will be encouraged to sift through the content and make their own.
Game mods, remixes, comics, and more are all encouraged by the developer.Let’s hope people take him up on the offer! You can check out all of the game’s assets here.
Valve add a Prestige option to the Dota Underlords ‘City Crawl’ mode to increase the challenge
Dota Underlords, the curious blend of Dota lore and characters in an auto-battling strategy game has a brand new update out as it continues to see a healthy amount of players since release.After leaving Early Access in February, it seems to have found its place with many more than ten thousand players on it regularly.With the full release came the City Crawl game mode, a special mode with various puzzle challenges that sees you attempt to take over a city.As you do it, you can unlock rewards and it’s proven quite popular.Now Valve has boosted this mode with the option to Prestige through it.
This will reset it, make it harder and allow you to earn more (and you can do it multiple times).If you complete it again during this you will get a restige seal on your Wanted Poster, as well as a flashy crown for all of your Underlords in-game.Enjoy the Easter Game !
Thanks to Franklin Weng, who has launched the idea, coordinated the project and provided the Chinese localization, and to the Japanese localization of Naruhiko Ogasawara, the Spanish localization of Daniel Armando Rodriguez and the Italian localization of Italo Vignoli, we offer a small Easter Game to play around the concept of Software and Document Freedom, and the Open Document Format.
Of course, with billions of people confined in their houses because of the COVID-19 pandemic, there is nothing to celebrate, so this is just a nice and gentle way to stress the importance of open document standards for our community.Click on the eggs to launch the Easter Game.Alexander Mikhaylenko: On windows and titlebars Recently, I’ve been working on a few widgets for libhandy to provide applications more flexibility with how to handle their titlebars.But doesn’t GTK already allow this? Let’s take a look.
First, GTK has a widget called GtkHeaderBar.It looks like a titlebar, has a close button, a title, a subtitle and allows to add widgets at the left or right sides, or to replace title and subtitle with a custom widget.Second, there’s gtk_window_set_titlebar() function that allows to set a widget as a custom titlebar.GTK will place that widget above the main window area, and then it can be dragged to move the window, and will handle right click menu, double click and middle click.
Additionally, GTK will draw client-side window border and/or shadows and provide an area to resize the window with.Naturally, GtkHeaderBar is a perfect fit for it, although nothing is preventing other widgets from being titlebars.If nothing is set, GtkWindow will use a GtkHeaderBar with a special style class (.default-decoration) as a titlebar on Wayland, or legacy decorations on X11.This approach works well if an application just wants to have a titlebar with some widgets in it.However, in many cases it’s more complex.Let’s take a look at some cases that are difficult or impossible to implement right now.SUSE and Red Hat Leftovers SAP Data Intelligence Benefits From Linux And Open Source
If SAP customers already use Suse Linux Enterprise Server for SAP Applications (SLES for SAP) in combination with Hana or S/4, they will also want to use Suse solutions in combination with SAP Data Hub and Data Intelligence, as it leads to beneficial technological continuity.SUSE CEO: avoiding disruption with open source and how her focus has changed
In March 2019, the company become independent from MicroFocus, and today continues to provide all of the open source based operating systems that power the applications of mission critical systems.
The open source technology is also embedded inside medical device components like CAT scans and mammogram machines.SUSE is led by Melissa Di Donato, former Women in IT Awards winner, who became the company’s first female CEO in July 2019.“We are the technology backbone that powers many and most mission critical systems and applications.Coupled with that we’ve got a cloud-based application platform for storage and our Container-as-a-Service business as well,” she told Information Age during a recent interview.A tip to play audio (and video) in a browser
She uses Fedora on her laptop and Firefox as the browser.All of the online tools that the institution uses works just fine.She is able to share presentations, tabs from browsers showing websites etc.The one challenge she encountered was in playing some audio files that are on her laptop.
For some reason that online platform is not able to pick up the VLC player that will be playing the audio and shared to her students.Did not matter what audio tool was used (Totem, Audacity (yes, that’s an overkill)), that window was not showing up as being shareable.
It could be something to do Wayland being used, but I did not want that to be the issue and that it should work everywhere.
I have heard that there is already a number of Debian Developers working for Red Hat, so if you happen to be one of them, I hope we’ll get in touch ! COVID and Openwashing Mercedes-AMG F1 and UCL open-source breathing aid designs
Mercedes-AMG F1 and University College London (UCL) have made the designs for a reverse-engineered breathing aid freely available to help the global fight against COVID-19.Details can be downloaded for free at a new UCL COVID-19 research hub.The package includes the designs, plus specifications of materials, tools and equipment required, and the fabrication time for each part.#HackCorona 2.0: Open-source hardware, telehealth & pandemic forecasts
According to WHO, it took more than 3 months to reach the first 100,000 confirmed cases of coronavirus worldwide, but only 12 days to reach 200,000, 4 days to reach 300,000, 3 days to reach 400,000 and another 5 to reach 700,000.China’s cases rocketed in the early weeks of the outbreak but curbed before other significant outbreaks had happened.Now, the US has the most number of confirmed cases.
Can we predict where the virus hits next? Greece currently faces over 1800+ coronavirus cases.As of now, over 200 people have recovered but 81 people died.With a disciplined approach the Greek Government is implementing, the outbreak could be very well under control.However, based on the experience of other European countries and taking into consideration the threats of an economical crisis, easily implementable solutions, will help manage the current state of affairs better, avoid overloading the healthcare system and putting additional burden on the Greek economy.
Healthcare Gets a Dose of Open-Source, But Will It Cure Coronavirus?
The crypto and open-source community have been working hard to stamp out the spread of Coronavirus.These healthcare efforts have been manifested in several initiatives from ethical tracking measures, 3D printing schematics, and crypto-based charity campaigns.It’s not just the virus they’re fighting either.

A group of Israeli researchers and experts from a variety of companies, governmental organizations and non-profits have partnered to create a low-cost ventilator whose blueprints, design and codes are completely open-source and that has the potential to save millions of lives as the coronavirus crisis continues to sweep through the world.Dr.
Eitan Eliram, the project coordinator of the initiative, told The Jerusalem Post that in the days since the material has been made available online, over 30,000 people have accessed the website and over 100 groups of experts from all over the world – including Iran, Egypt, South Africa, Guatemala, Italy and the United States – are already working to build up their first prototypes.Researchers Develop Simple ‘Open Source’ Ventilator
As the need for ventilators continues to grow around the world, manufacturers are ramping up production and some industries are shifting to ventilator production.But, there are also out-of-the-box approaches being worked on.A team of researchers around the world have developed a basic ventilator design that can be built using parts from the hardware store.
It’s called the Open Source Ventilator Project.Latest News Docker builds open source community around Compose Specification
“Opening the specification will allow innovation to flourish and deliver more choices to developers, accelerating how development teams build and ship applications,” Docker wrote in a blog post.“Open governance will benefit the wider community of new and existing users with transparency and the ability to have input into the future direction of the specification and Compose based tools.” Previously Compose did not have a published specification, and was tied to the implementation, and to specifics of the platforms it shipped on.Now, Compose simplifies the code to cloud process and toolchain for developers by allowing them to define a complex stack in a single file and run it with a single command.This eliminates the need to build and start every container manually, the company explained.
Docker intends to submit the specification to an open source foundation “to enhance the playing field and openness.”.
