Linux 5.5 To Finally Expose NVMe Drive Temperatures Via HWMON
Linux for years has supported monitoring NVMe drive temperatures when installing the nvme user-space utility and run as root, etc. But now finally with Linux 5.5 the kernel is supporting NVMe drive temperature reporting through the hardware monitoring "HWMON" infrastructure alongside other hardware sensors.
Come the Linux 5.5 stable release in early 2020 is the NVMe HWMON support to allow reporting the current NVMe drive temperature sensor(s) and min/max thresholds via this kernel infrastructure. This in turn allows user-space to simply query the data over sysfs without the need for any utilities, no root requirement, and should gracefully work with the various programs that report HWMON sensor readings to Linux desktop users.

PHP 5.3 To PHP 7.4 Performance Benchmarks On AMD EPYC
With the big PHP 7.4.0 release due out next week, yesterday we published our PHP 7.4.0 benchmarks using the near-final build for this annual update to PHP. Those benchmarks compared previous releases as far back as PHP 5.6. But out of curiosity after that article I went to do some benchmarks going back to PHP 5.3 through PHP 7.4 and PHP 8.0-dev.
With the AMD EPYC 7642 server running Ubuntu 19.10 used in yesterday's article, I ran the final PHP 5.3/5.4/5.5 benchmarks added in to yesterday's data. So for those curious how the historical PHP5 performance compares to the imminent PHP 7.4, these benchmarks are for your enjoyment today.

Wine Patches Coming To Allow UMIP Emulation - Works Around Issues For Ryzen 3000
Coming up this weekend with the Linux 5.4 kernel is emulation/spoofing of the SGDT/SIDT/SMSW instructions around UMIP for allowing newer 64-bit Windows games to run on Wine and Steam Play (Proton). With newer CPUs like the AMD Ryzen 3000 series that support UMIP, these instructions are not allowed to run in user-space with Wine due to UMIP. So while the first stable kernel release is about to land with this support, some Wine-based emulation not contingent on the kernel patches is also in the works.

KF6 Sprint - Day One
Today we started our KF6 sprint at the MBition office in Berlin.
Beside the people attending in person, we have David Faure joining us via web conference.
Thanks already to the people at MBition that spend time on making it possible to host the sprint there.
First stuff to be discussed were some high level things, like does the monthly release scheme work out well. Short answer: yes The short period works well, allows people to fix issues directly in frameworks and still have that reasonable fast provided to the users. And the overhead of release creation is low, thanks to automation.

Goldman Sachs is planning on giving some of its most valuable software to Wall Street for free
Goldman Sachs wants to give away some of its most valuable software.
The investment bank spent countless hours over 14 years developing a platform called Alloy to help it access and analyze the growing set of financial databases being created across the firm. Now Goldman is taking the unusual step of making that program, as well as the language underlying it, available to the rest of Wall Street for free as open-source software in collaboration with a nonprofit called Finos.
The software and language "have grown to become critical tools within our firm across the trade lifecycle that help us price, assess and evaluate risk, clear transactions, and perform regulatory reporting," said Neema Raphael, co-chief data officer at Goldman. By making it publicly available, "we'll unlock tremendous value for the industry when we co-develop and share models."

Open source transparency comes to root of trust hardware
Geopolitics have put enterprise data centers in the crosshairs of international espionage. From all corners of the globe, hackers of all sorts, including those aligned with national spy agencies, are zeroing in on hardware roots of trust.
For any computing platform, the root of trust is the ultimate line of defense against cybersecurity attacks. No matter how secure your operating system and applications appear to be, they are acutely vulnerable if running on a hardware platform whose root of trust has been compromised by an unauthorized party.

Cloud Print becomes the latest product to face Google death squad
At the end of 2020, after over a decade in beta, Google will pick up its product-ending shotgun and take Cloud Print for a talk behind the back shed, from which it will never return.
"Beginning January 1, 2021, devices across all operating systems will no longer be able to print using Google Cloud Print," Google said in a support note.
"We recommend that over the next year, you identify an alternative solution and execute a migration strategy."
Last week for its own Chrome OS operating system, Google added CUPS printing, which it will use instead of Cloud Print.

Google shuts down its Cloud Print service after 10-year Beta
Google revealed plans to shut down Cloud Print, a cloud-based printing solution, at the end of 2020 permanently.
The company launched Cloud Print back in 2010 as a solution to print from any Internet connected device to compatible printers. The main benefit of the solution was that users did not have to install printer drivers on their client devices and that devices did not need to be in the same local network as the printer. The solution enabled printing on devices without official support from the printer's manufacturer or drivers for that particular device.
On Windows users could install the Google Cloud Printer application to add cloud printing functionality to the operating system.

Google Cloud Print will be shut down on December 31, 2020
After offering printing from any device, from any location, to any web-connected printer with Cloud Print, Google is shutting down the service that has technically been a beta product since 2010. Cloud Print will be gone by the end of next year and users will need to find an alternative before December 31, 2020. Chrome OS, which originally relied on Cloud Print entirely for printing needs, eschewing the need to develop native printing controls, is now going full native.
Chrome OS already handles some administrative tasks for printers that use the Common Unix Printing System (CUPS). Google promises to expand administrative options through the end of the year, and add more robust support for external print servers and other security policy administration in 2020. Since Chrome OS and its apps relied entirely on Cloud Print, Google will also be developing APIs for third-party developers to handle printing tasks.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
