BcacheFS – Jupiter Broadcasting

What do we need to get started? Two things: a reasonably recent browser (WebRTC is supported in current versions of Chrome, Firefox, Edge and Opera but not in Safari or many mobile browsers) and drumroll – a server.

An Introduction to the ss Command

The ss command is a tool used to dump socket statistics and displays information in similar fashion (although simpler and faster) to netstat. The ss command can also display even more TCP and state information than most other tools. Because ss is the new netstat, we’re going to take a look at how to make use of this tool so that you can more easily gain information about your Linux machine and what’s going on with network connections.

Systemd for (Impatient) Sysadmins

…and although I’m at philosophical odds with it at some levels, I see no reason why everybody shouldn’t understand it a bit better – especially now that most people will need to deal with it on their favorite distros.

Linux tracing systems & how they fit together

The thing I learned last week that helped me really understand was – you can split linux tracing systems into data sources (where the tracing data comes from), mechanisms for collecting data for those sources (like “ftrace”) and tracing frontends (the tool you actually interact with to collect/analyse data). The overall picture is still kind of fragmented and confusing, but it’s at least a more approachable fragmented/confusing system.

How Microsoft brought SQL Server to Linux

“Talking to enterprises, it became clear that doing this was necessary,” Kumar said. “We were forcing customers to use Windows as their platform of choice.” In another incarnation of Microsoft, that probably would’ve been seen as something positive, but the company’s strategy today is quite different.

Formal Verification of WireGuard Protocal

The WireGuard protocol, described in the technical paper, and based on Noise, has been formally verified in the symbolic model using Tamarin. This means that there is a security proof of the WireGuard protocol.

ZFS Is the Best Filesystem (For Now…)

ZFS should have been great, but I kind of hate it: ZFS seems to be trapped in the past, before it was sidelined it as the cool storage project of choice; it’s inflexible; it lacks modern flash integration; and it’s not directly supported by most operating systems. But I put all my valuable data on ZFS because it simply offers the best level of data protection in a small office/home office (SOHO) environment.

Smach Z – The Handheld gaming PC

“Hi Smachers,
AMD has kindly agreed to let us inform backers about the new SoC upgrade. We can officially confirm that we are moving to the latest generation AMD technology which will be based on Ryzen and Vega technology.
We’re working together with AMD to bring the best performance to SMACH Z, so it will be the most powerful handheld console in the market. The new generation looks amazing, and we want to thank AMD for all the support and efforts contributed to our project.
At this point we cannot say any more information, but I hope that this announcement works to alleviate the long waiting and to confirm that SMACH Z will feature the best hardware when it will become available.
This decision has been taken after a thorough analysis of the situation. Being forced to move away from Romb.io technology and having to redo the SoC integration has moved our schedule opening the opportunity to bring the latest technology to our design. For the moment this announcements is private only for backers.
Thanks for your support!”

Beginner-Friendly Vulkan Tutorials

For those who don’t know, Vulkan is a new graphics API– in other words, a fresh new way to talk to your GPU and make it do things. It’s managed by the Khronos Group, which means no one corporation controls it. It’s pretty cool, and anyone who wants to do work on GPUs (not restricted to graphics programmers!) should at least have a high level knowledge of what it is.

vkmark: more than a Vulkan benchmark

Ever since Vulkan was announced a few years ago, the idea of creating a Vulkan benchmarking tool in the spirit of glmark2 had been floating in my mind. Recently, thanks to my employer, Collabora, this idea has materialized! The result is the vkmark Vulkan benchmark

Announcing Mageia 6, finally ready to shine!

The whole Mageia community is extremely happy to announce the release of Mageia 6, the shiny result of our longest release cycle so far!

Though Mageia 6’s development was much longer than anticipated, we took the time to polish it and ensure that it will be our greatest release so far.

Highlights of Mageia 6

KDE Plasma 5 replaces the previous KDE SC 4 desktop environment
Support for AppStream and thus GNOME Software and Plasma Discover
Support for Fedora COPR and openSUSE Build Service
Successful integration of the ARM port (ARMv5 and ARMv7) in the buildsystem
While not a new feature, Mageia 6 supports over 25 desktop environments and window managers

Kodi Is Getting A Proper Netflix Plugin

Desktop Linux’ future growth might depend on Electron/Web appssum

Then I wrote a script, nativefier-freedesktop, that takes *.webapp file as input, build the app with Nativefier and install it, so you can launch it from your app menu. It can include custom CSS style and JavaScript code to be injected during the building. The icon can be themed by icon themes.

GitHub – jiahaog/nativefier: Make any web page a desktop application

Nativefier is a command line tool that allows you to easily create a desktop application for any web site with succinct and minimal configuration. Apps are wrapped by Electron in an OS executable (.app, .exe, etc.) for use on Windows, OSX and Linux.

A New Linux File-System Aims For Speed While Having ZFS/Btrfs-Like Features

This new file-system is Bcachefs. BcacheFS is based on _BCache, the Linux kernel block layer cache_for pairing a large-capacity hard drive with a low-capacity, high-performance solid-state drive to act as a cache. In developing this block layer cache, Kent Overstreet (the primary Bcache/Bcachefs) developer realized they were basically writing their own file-system in the process. He explained, “the bcache codebase has been evolving/metastasizing into a full blown, general purpose posix filesystem – a modern COW filesystem with checksumming, compression, multiple devices, caching, and eventually snapshots and all kinds of other nifty features…I and the other people working on bcache realized that what we were working on was, almost by accident, a good chunk of the functionality of a full blown filesystem – and there was a really clean and elegant design to be had there if we took it and ran with it.”

PERFORMANCE:

I’m not really focusing on performance while there’s still correctness issues to
work on – so there’s lots of things that still need to be further optimized, but
the current performance numbers are still I think good enough to be interesting.

Here’s some dbench numbers, running on a high end pcie flash device:
