Audio capture in Linux on Chromebooks testing about to begin in Chrome OS

Filed under
OS
Linux

I may be one of the few that wants to record audio using a Linux app on my Chromebook, but I’m going to share this news anyway. The effort to bring audio capture support to Project Crostini that started in February is nearly ready for testing, at least on a limited basis.

’ve tried to start my conainer with the new –enable-audio-capture argument using the Dev Channel of Chrome OS 79 but the extra parameter isn’t yet recognized. Hopefully, it arrives in the next Dev Channel update for Chrome OS.

My specific need for audio capture is when using Audacity, an open-source audio editing tool available for Linux, as well as Windows and macOS.

Proper Linux Screen Sharing Coming to Chromium & Electron Apps like Discord

Filed under
Linux

A patch to add ‘screen enumeration’ to the Chromium browser is currently pending merge upstream.

Once this fix is accepted Chromium and Chromium-based apps (like Discord) will finally support full screen sharing on Linux in a manner similar to that on Windows and macOS.

Not being a multi-monitor user, or someone who shares their screen often, I wasn’t aware of this particular limitation until recently.

So I’ll explain.

Linux-powered NVR system offers up to eight PoE+ ports

Filed under
Linux

SolidRun’s rugged “ClearFog GTR A385” NVR system runs Linux on a Marvell Armada A385 and offers 4x 90W PoE++ or 8x 30W PoE+ camera ports plus powered GbE PoE WAN and 2.5Gbps SFP+ ports, 3x mini-PCIe, and optional 2x SATA.

SolidRun announced a fanless network video recorder for indoor or outdoor surveillance and industrial infrastructure applications. The ClearFog GTR A385 is available in an unpriced S4 model and a $345 L8 model. Both provide 4x PoE++ Gigabit Ethernet ports for 90W Power-over-Ethernet control of cameras. The L8 model provides four more GbE/PoE ports that can be configured with the first four ports to alternatively support 8x 30W PoE+ (802.3bt) connections. All the ports are 802.3at/af/bt-compliant power sourcing equipment (PSE) ports with up to type 4 PoE support.

Manjaro Linux 18.1.0 Juhraya Cinnamon - Spicy but sweet

Filed under
Linux
Reviews

You know how the popular saying goes. When it rains ... people drive slowly just to annoy you. But as it happens, I received a bunch of emails from people asking me two things: 1) Why have I not recently done any more Cinnamon reviews (other than Mint)? 2) When am I going to review the latest version of Manjaro 18.1 Juhraya?

The answer to these question is: yes. At the same time! I decided to try Manjaro Cinnamon, not something I've done before, so it should be an interesting, refreshing and hopefully worthwhile exercise. The test box will be the same one I used for the Illyria Xfce test, so we can compare things in earnest - and accurately. This is an eight-book mixed Windows & Linux box, and it comes with UEFI, Intel graphics, 16 sweet partitions, and another instance of Manjaro that we won't touch in this review. Begin to start.

Pacman 5.2 Release

Filed under
GNU
Linux

We have a clear winner. Although I’m sure that at least half of those are in responses to bugs he created! He claims it is a much smaller proportion… And a new contributor in third.

What has changed in this release? Nothing super exciting as far as I’m concerned, but check out the detailed list here.

We have completely removed support for delta packages. This was a massively underused feature, usually made updates slower for a slight saving on bandwidth, and had a massive security hole. Essentially, a malicious package database in combination with delta packages could run arbitrary commands on your system. This would be less of an issue if a certain Linux distro signed their package databases… Anyway, on balance I judged it better to remove this feature altogether. We may come back to this in the future with a different implementation, but I would not expect that any time soon. Note a similar vulnerability was found with using XferCommand to download packages, but we plugged that hole instead of removing it!

Forbes Raves Upcoming Linux Desktop will enclose Windows 10 and macOS

Filed under
GNU
Linux

Forbes senior employee Jason Evangelho dedicated an entire article to an upcoming update for a Sino-domestic Linux distribution:

If you haven't paid attention to a bit of Linux desktop distribution called Deepin, it's time to put it on your radar. Remember that Huawei Deepin chose to ship on their MateBook laptop lineup. Remember that Deepin Cloud Sync (for system settings) is a great, progressive feature that every Linux distro must use. Remember that the retractable control center from the future looks like something sexy and sensible. But looking at 2020, Deepin is absolutely breathtaking.

This is without a doubt the nicest desktop environment I have ever seen … For me, the UX is more intuitive and pleasant than macOS and Windows 10. And luckily a quick setting can also transform Deepin into the traditional Windows or macOS desktop paradigm's that you are already familiar with. Hell, even the installer is a relief.

[libre-riscv-dev] power pc

Filed under

So as you know, the RISCV Foundation is seriously impeding progress. There
is huge momentum around RISCV itself, however as far as open *innovation*
is concerned, the sheer arrogance of the Foundation in failing to respect
the combination of Libre goals and business objectives has us completely
isolated from key critical resources such as the closed secret lists and
wiki.

We cannot even get access to documentation explaining how to propose new
extensions.

I have been considering for some time to reach out to MIPS and PowerPC.
Yesterday I wrote to the OpenPower Foundation and was really surprised and
delighted to hear back from Hugh Blemings, whom I worked with over 20 years
ago.

I outlined some conditions (no NDAs, open mailing lists, use of
Certification Marks and Compliance Suites) and he replied back that this
was pretty much along the lines of what they were planning.

I will have a chat with him some time, in the meantime I found the spec:

https://openpowerfoundation.org/?resource_lib=power-isa-version-3-0

It is eeenooormous, however Hugh reassures me that they want to break it
into sections.

Why would we even consider this?

The lesson from RISCV is really clear: if the ISA is set up as a cartel,
Libre innovation is not welcome.

If we had a goal to just *implement* a *pre existing* Extension, there
would be no problem.

It is the fact that we wish to implement entirely new extensions, for CPU
and GPU *and* VPU purposes, but not as a separate processor (which would be
classified as "custom") that is the "problem".

So starting at page 1146, we need to work out how to shoe horn a ton of
stuff into the ISA, as well as fit 16 bit compressed in as well.

Ubuntu: AMD Support, NVIDIA GPU Operator and More

  • Ubuntu 19.10 Doesn't Ship With AMD Navi / Radeon RX 5700 Support Working, But Easy To Enable

    While last week's release of Ubuntu 19.10 "Eoan Ermine" is new enough for Radeon RX 5700 series support with the Linux 5.3 kernel and Mesa 19.2, it doesn't actually work out-of-the-box for these Navi graphics cards. While the principal driver components of the Linux kernel and Mesa3D (for RadeonSI OpenGL and RADV Vulkan) are new enough with Navi support, Ubuntu 19.10's support isn't rounded out because its linux-firmware package isn't new enough for containing the necessary Navi firmware binaries required for the open-source driver usage. So if booting a clean Ubuntu 19.10 install with Radeon RX 5700, you are likely to just see a blank screen.

  • NVIDIA GPU Operator – Simplifying AI/ML Deployments on the Canonical Platform

    Leveraging Kubernetes for AI deployments is becoming increasingly popular. Chances are if your business is involved in AI/ML with Kubernetes you are using tools like Kubeflow to reduce complexity, costs and deployment time. Or, you may be missing out! With AI/ML being the tech topics of the world, GPUs play a critical role in the space. NVIDIA, a prominent player in the GPU space is one of the top choices for most stakeholders in the field. Nvidia takes their commitment to the space a step ahead with the launch of the GPU Operator open-source project at Mobile World Congress LA.
