Hangover Alpha 2 Lets Windows x86/x64 Programs Run On ARM64, POWER 64-bit

Filed under
Software

The Wine program for running Windows games/applications on Linux and other platforms can run on a number of different architectures, but Wine doesn't handle the emulation of running Windows x86/x64 binaries on other architectures like 64-bit ARM or PowerPC. But that's what the Wine-based Hangover is about with currently allowing those conventional Windows binaries to run on AArch64 (ARM64) and 64-bit POWER too.

Hangover started out with a focus on Windows x64 binaries on ARM64 in looking at the possible use-case of running Windows software on ARM mobile devices and more. This year with the help of Raptor Computing Systems there has been Hangover support added for IBM POWER 64-bit.

Jonathan Dieter: Switching to OSTree

Filed under
Red Hat

Given our shift towards containers, the most obvious solution would have been to switch to Fedora CoreOS, but a number of our call servers have Sangoma telephony cards with kernel drivers that are, unfortunately, out-of-tree. While there are some elegant ways to load custom kernel modules into Fedora CoreOS, we needed a more stable kernel, due to the (lack of) speed in which these modules are updated to build with new kernels.

So we decided to go with a custom OSTree distribution (surprisingly named SpearlineOS), built using rpm-ostree and CentOS 8. SpearlineOS has two streams, staging and production. At the moment, we’re manually building each new release, pushing it to staging, running it through some smoke tests, and, then, finally, pushing it to production. We are in the process of setting up a full staging environment with automatic builds and automatic promotion to production once a build has been functioning correctly for set period of time. We’ve also setup greenboot in SpearlineOS so that our servers are able to fail back to an older release if the current one fails for any reason.

  • This week in KDE: Continuous bug massacre

    This week the bug squashing continues at full speed! We’ve made short work of tons of bugs throughout our software stack, including the infamous login sound bug, some very important and longstanding issues with extended attributes, and a ton of quality-of-life improvements for the Plasma Wayland session.

    But we also managed to add a few nice new features that I think you’ll like.

  • KDE Saw A "Bug Massacre" This Week With Better NVIDIA Wayland Experience, Many Fixes

    The bug fixing in KDE land continues and ends the month with a "bug massacre", for how KDE developer Nate Graham describes it in his weekly recaps. 

    Graham also commented of this week's KDE efforts as "bug squashing continues at full speed!" Some of the work that got addressed this week for KDE includes: 

    - The KDE Plasma Wayland session no longer requires manually setting an environment variable to make NVIDIA GPUs with the proprietary driver properly function. This change is with KDE Plasma 5.20.2 for offering a better KDE Wayland out-of-the-box experience on NVIDIA's proprietary driver. This is addressed by automatically detecting the NVIDIA proprietary driver and EGLStreams rather than making the user set KWIN_DRM_USE_EGL_STREAMS. 

Chromium Browser Now Officially Available in Linux Mint and LMDE, Here’s How to Install It

Filed under
Linux

After making it hard for users to install the Chromium web browser on their distributions by deciding to drop support for Ubuntu’s Snap universal packages with the Linux Mint 20 release onwards, the Linux Mint developers are now packaging Chromium and distributing it trough the official repos.

Chromium is not only available in Linux Mint, but also in the Debian spin LMDE (Linux Mint Debian Edition). Users can now easily install the open-source web browser with a few mouse clicks. Depending on the edition you’re using (Cinnamon, MATE or Xfce), all you have to do is open the Software Manager and install Chromium.

Kick Microsoft Windows 10 to the curb — switch to Ubuntu-based Linux Lite 5.2 today!

Filed under
Linux
Ubuntu

Many technology pundits have been theorizing and discussing the possibility of Windows eventually becoming a Linux-based operating system. They cite the fact that Microsoft has become less dependent on Windows for revenue, making it silly to dedicate so many resources to it. Not to mention, Microsoft has certainly cozied up to both the Linux and open source communities nowadays.

Do I think Microsoft will make this move one day? Who knows. Years ago I'd say it was crazy, but in 2020, the company's flagship mobile device -- the Surface Duo -- runs the Linux-based Android. For now, Linux-based Windows remains pure conjecture. With that said, I think we can all agree on one thing -- Linux is the future of desktop computing, with Chrome OS leading the sea change.

A Brief History of Ubuntu Touch

Filed under
Ubuntu

Sensing the tech trend, Ubuntu tried its hands on creating a Linux-based mobile operating system. The first announcement came a decade back and six years down the line, Ubuntu closed the curtains on the project.

What went wrong? How it started? Is Ubuntu Touch still alive? Let’s take a look at the history of Ubuntu Touch in chronological order.

The Ubuntu Touch project began with a blog post by Canonical founder Mark Shuttleworth. The blog post, dated October 31, 2011, started with a bold prediction: “By 14.04 LTS Ubuntu will power tablets, phones, TVs and smart screens from the car to the office kitchen, and it will connect those devices cleanly and seamlessly to the desktop, the server and the cloud.”

Shuttleworth went on to explain that this move would be accomplished mainly through the use of the company’s new desktop environment, Unity. (Unity was introduced in Ubuntu 10.10.) “Unity, the desktop interface in today’s Ubuntu 11.10, was designed with this specific vision in mind.”

Control Philips Hue Lights on Ubuntu with this GNOME Extension

Filed under
GNOME
Ubuntu

In 2016 we wrote about a GTK app for managing Phillips Hue lights on the Linux desktop. Though very handy that tool hasn’t been updated for a while. But no worries: now there’s something better.

If you use Ubuntu (or any distro with GNOME Shell) and your Hue bulbs are connected to a Hue Bridge you can turn lights on or off, control their brightness, and even change their colour — directly from your desktop PC.

The brightly named “Hue Lights” GNOME Shell extension is able to discover Hue Bridges (or connect directly by IP). It lets you manage individual bulbs or groups of lights in “zones” (e.g., ‘bedroom lights’, ec).

  • Status update, October 2021

    On this dreary morning here in Amsterdam, I’ve made my cup of coffee and snuggled my cat, and so I’m pleased to share some FOSS news with you. Some cool news today! We’re preparing for a new core product launch at sr.ht, cool updates for our secret programming language, plus news for visurf. Simon Ser has been hard at work on expanding his soju and gamja projects for the purpose of creating a new core sourcehut product: chat.sr.ht. We’re rolling this out in a private beta at first, to seek a fuller understanding of the system’s performance characteristics, to make sure everything is well-tested and reliable, and to make plans for scaling, maintenance, and general availability. In short, chat.sr.ht is a hosted IRC bouncer which is being made available to all paid sr.ht users, and a kind of webchat gateway which will be offered to unpaid and anonymous users. I’m pretty excited about it, and looking forward to posting a more detailed announcement in a couple of weeks. In other sourcehut news, work on GraphQL continues, with paste.sr.ht landing and todo.sr.ht’s writable API in progress. Our programming langauge project grew some interesting features this month as well, the most notable of which is probably reflection. I wrote an earlier blog post which goes over this in some detail. There’s also ongoing work to develop the standard library’s time and date support, riscv64 support is essentially done, and we’ve overhauled the grammar for switch and match statements to reduce a level of indentation for typical code. In the coming weeks, I hope to see date/time support and reflection fleshed out much more, and to see some more development on the self-hosted compiler. [...] The goal of this project is to provide a conservative CSS toolkit which allows you to build web interfaces which are compatible with marginalized browsers like Netsurf and Lynx.

  • My Favorite Warnings: uninitialized | Tom Wyant [blogs.perl.org]

    This warning was touched on in A Belated Introduction, but I thought it deserved its own entry. When a Perl scalar comes into being, be it an actual scalar variable or an array or hash entry, its value is undef. Now, the results of operating on an undef value are perfectly well-defined: in a nuneric context it is 0, in a string context it is '', and in a Boolean context it is false. The thing is, if you actually operate on such a value, did you mean to do it, or did you forget to initialize something, or initialize the wrong thing, or operate on the wrong thing? Because of the latter possibilities Perl will warn about such operations if the uninitialized warning is enabled.

"They want a unified development platform where developers can build, modify, and deploy applications residing in both containers and VMs in a common, shared environment," the pair added.

  • The Dell Inspiron 15 3501 supports Linux

    With the Inspiron 15 3501, Dell has a 15.6-inch office laptop in its lineup with its technology housed in a slim, matte-black plastic case. The chassis lacks stability: The lid and the base unit in particular can be twisted a bit too much. The matte display (Full HD, IPS) offers stable viewing angles, good contrast, and decent color reproduction. However, the brightness and color-space coverage are too low. The built-in combination of the Core i7-1165G7 processor, 16 GB of RAM (dual-channel mode), and a 512 GB NVMe SSD (M.2 2230) equips the laptop for office and Internet applications. If the storage space isn't enough, an additional 2.5-inch storage drive can be installed. You can also replace or expand the RAM.

The intricacy of the ingenious mechanism is laid bare in [Mechanistic]’s 3D-printed scale model of a small section of the grand piano keyboard. The ‘grand’ distinction here is piano length-agnostic and simply refers to any non-upright. Those operate the same way, but are laid out differently in order to save space.

Revolutionary as it was at the time, by today’s standards its display is rather primitive, with no backlight and a usable area measuring only 47 mm x 44 mm. [Martoni] figured out a way to solve this, by developing GbVGA and GbHdmi, two projects that enable the Game Boy to connect to an external monitor. This way, you can play Super Mario Land without straining your eyes, and we can also image potential uses for those who stream their gameplay online.

  • Why digital transformation demands a change in leadership mindset

    Recently a key retail executive forecast that their industry will change more in the next five years than it has in the past fifty. Another executive believes society will change more in the next fifty years than it has in the last three hundred. A recent headline declared that, “We are approaching the fastest, deepest, most consequential technological disruption in history”, and Ray Kurzweil, Google’s Director of Engineering and co-Founder of Singularity University, has said that there will be fourteen internet size revolutions in the next decade. Whichever way you look at it, things are shifting… fast. When you speak with the visionaries and entrepreneurs actually building the solutions of tomorrow, from on-demand retail to vertical farms, and ask how far into this new era we are, almost universally the reply is: “only one percent”. Imagine then, where we will be ten years from now? How about 50? Major industries, from medicine to energy to travel to entertainment, are radically transforming, putting pressure on others such as manufacturing, construction, transportation, finance, education…frankly, all of it. What an extraordinary opportunity this presents.

  • DevSecOps lessons learned during a pandemic | The Enterprisers Project

    As we’ve seen over the past year and a half, the pandemic has accelerated digital transformation and forever changed workplace culture. Increased reliance on digital tools has elevated the value of DevSecOps, as enterprises of all sizes and across all industries realize the importance of automating and integrating security at every phase of the software development lifecycle – from initial design through integration, testing, deployment, and product delivery. My engineering team was no exception to this shift – we had to quickly prepare to build a new Virtana SaaS platform and deliver several new modules, all while working remotely. Here I’ll share some observations, pain points, and lessons learned to help others intelligently embrace DevSecOps best practices within their teams.
