VirtualBox 6.0.8 Released to Make Shared Folders Work with Linux Kernel 3.16.35

Oracle released VirtualBox 6.0.8, a new monthly maintenance for its open-source and cross-platform virtualization software with more stability and reliability improvements, as well as fixes for critical bugs.

VirtualBox 6.0.8 is a small update, but it addresses some important problems to make your VirtualBox experience better. For starters, it fixes the saved state resume failures, as well as mouse click pass-through issues that users experienced in multi-screen virtual machines, and a crash that occurred when shutting down a virtual machine without graphics controller.

This release also adds some important improvements for Linux platforms, such as support for shared folders on systems powered by Linux kernel 3.16.35 LTS, support for correctly handling the read-only flag of shared folders, and support for successfully building the VirtualBox kernel module in both non-default and debug build setups.

User interface improvements, Windows fixes

Canonical Releases Ubuntu Updates to Mitigate New MDS Security Vulnerabilities

Canonical has released today new updates for all of its supported Ubuntu Linux operating system series to mitigate the recently disclosed Microarchitectural Data Sampling (MDS) security vulnerabilities in Intel CPUs.

Four new security vulnerabilities affecting Intel microprocessor have been publicly disclosed earlier, and Intel already released updated microcode firmware to mitigate them, but in the case of Linux-based operating system these flaws cannot be addressed only by updating the CPU firmware, but also by installing new Linux kernel versions and QEMU patches.

The vulnerabilities (CVE-2018-121… (read more)

Nvidia 430.14 Linux Driver Improves Performance for DiRT 4 and Wolfenstein II

Nvidia has released today new long-lived stable graphics drivers for Linux, BSD, and Solaris systems to add a bunch of various enhancements, bug fixes, and performance improvements for some games.

The Nvidia 430.14 display driver is now available for Linux-based operating system with performance improvements for the DiRT 4 video game, which was ported last month by UK-based video games publisher Feral Interactive to Linux and Mac platforms, as well as for the Wolfenstein II: The New Colossus first-person shooter video game, which is available as a Steam Play title.

The Nvidia 430.14 display driver also adds new functionality to the Nvidia VDPAU driver, including support for decoding HEVC YUV 4:4:4 streams, new per-decoder profile capability, support for accessing YUV 4:4:4 surfaces, support for creating YUV 4:4:4 video surfaces, and support for allocating VDPAU video surfaces with explicit frame or field picture structure.

The Black Hole Becomes Visible With Half A Ton Of Hard Drives

Brace yourself. You can finally see how a black hole looks like. Up until today, no one really knew how a black hole looked like.

Finally, the day has come but it was no easy task.

The newly released image of a black hole (below) is a watershed moment for physics. Finally, we can put some of Einstein’s most famous predictions from a century ago to the test, but it was not as easy as pointing a big lens at the M87 galaxy and pressing a button. It took years of work and the collaboration of more than 200 scientists to make it happen. It also required about half a ton of hard drives.

What’s interesting about how the snapshot of the black hole was the length of time it took to put it together. It took years and a network of telescopes from around the world to capture the first real image of the black hole.

Data collection for the historic black hole image began in 2017 with a coordinated effort called the Event Horizon Telescope (EHT). That isn’t a single instrument but rather a collection of seven radio telescopes from around the world. The EHT used a principle called interferometry to combine the capacity of all those telescopes, creating a “virtual” telescope the size of the Earth.

The EHT had to collect a huge volume of data to deliver us this one image. Dan Marrone, Associate Professor of Astronomy at the University of Arizona says the EHT team had to install specialized super-fast data recorders on the various radio telescopes to handle the influx of measurements.

The now-famous image of a black hole comes from data collected over a period of seven days. At the end of that observation, the EHT didn’t have an image — it had a mountain of data.

(Via: https://www.extremetech.com/extreme/289423-it-took-half-a-ton-of-hard-drives-to-store-eht-black-hole-image-data_)

The data collected was just too massive for the internet to handle. The hard drives had to be flown by plane.

According to Marrone, 5 petabytes is equal to 5,000 years of MP3 audio. There’s simply no way to send that much data efficiently over the internet. It’s faster to

Google and Collabora Add Major Change to Linux Kernel 5.1 for Chrome OS Devices

Collabora and Google engineers have been working on a new, exciting new feature that would benefit users of Chrome OS and Android devices, which recently landed in the latest Linux 5.1 kernel series.

According to Collabora’s latest report on their contributions to the Linux 5.1 kernel, which arrived last week, it is now possible to mount and boot a mapped device by adding a kernel parameter via command-line at boot time, thus bypassing initramfs image. For Linux kernel 5.1, twelve Collabora’s developers also contributed 64 commits and 111 sign-offs, along with lots of bug reports and testing.
