Linus Torvalds Recognizes Linux's 'True' 30th Anniversary Date
by Peter Reutemann 26 Sep '21

26 Sep '21

'While it's been argued that Linux has four different "birthdays," last Friday saw the 30th anniversary of Linux's very, very first release — version 0.01. That special first release "was never publicly announced, and I only emailed a handful of people in private about the upload," Torvalds remembered on the Linux kernel mailing list. He no longer has copies of those announcement emails, "so there's no real record of that. The only record of the date is in the Linux-0.01 tar-file itself, I suspect." "Alas, the dates in that tar-file are for the last modification dates, not the actual creation of the tar-file," Torvalds wrote, "but it does seem to have happened around 7:30pm (Finnish time), so the exact anniversary was technically a couple of hours ago." So when the exact moment arrived for its 30th anniversary, Torvalds couldn't resist sharing the moment on the Linux kernel mailing list. "Just thought I'd mention it, since while unannounced, in many ways this is the true 30th anniversary date of the actual code."' -- source: https://linux.slashdot.org/story/21/09/25/0333233 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

First RISC-V Computer Chip Lands At the European Processor Initiative
by Peter Reutemann 23 Sep '21

23 Sep '21

'The Register reports: The European Processor Initiative (EPI) has run the successful first test of its RISC-V-based European Processor Accelerator (EPAC), touting it as the initial step towards homegrown supercomputing hardware. EPI, launched back in 2018, aims to increase the independence of Europe's supercomputing industry from foreign technology companies. At its heart is the adoption of the free and open-source RISC-V instruction set architecture for the development and production of high-performance chips within Europe's borders. The project's latest milestone is the delivery of 143 samples of EPAC chips, accelerators designed for high-performance computing applications and built around the free and open-source RISC-V instruction set architecture. Designed to prove the processor's design, the 22nm test chips -- fabbed at GlobalFoundries, the not-terribly-European semiconductor manufacturer spun out of AMD back in 2009 -- have passed initial testing, running a bare-metal "hello, world" program as proof of life. It's a rapid turnaround. The EPAC design was proven on FPGA in March and the project announced silicon tape-out for the test chips in June -- hitting a 26.97mm2 area with 14 million placeable instances, equivalent to 93 million gates, including 991 memory instances. While the FPGA variant, which implemented a subset of the functions of the full EPAC design, was shown booting a Linux operating system, the physical test chips have so far only been tested with basic bare-metal workloads -- leaving plenty of work to be done. Earlier today, the UK government released its 10-year plan to make the country a global "artificial intelligence superpower," seeking to rival the likes of the U.S. and China. "The so-called 'National Artificial Intelligence Strategy' is designed to boost the use of AI among the nation's businesses, attract international investment into British AI companies and develop the next generation of homegrown tech talent," reports CNBC.' -- source: https://hardware.slashdot.org/story/21/09/22/2057258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Security audit raises severe warnings on Chinese smartphone model
by Peter Reutemann 23 Sep '21

23 Sep '21

'The Lithuanian National Cyber Security Centre (NCSC) recently published a security assessment of three recent-model Chinese-made smartphones—Huawei's P40 5G, Xiaomi's Mi 10T 5G, and OnePlus' 8T 5G. Sufficiently determined US shoppers can find the P40 5G on Amazon and the Mi 10T 5G on Walmart.com—but we will not be providing direct links to those phones, given the results of the NCSC's security audit. The Xiaomi phone includes software modules specifically designed to leak data to Chinese authorities and to censor media related to topics the Chinese government considers sensitive. The Huawei phone replaces the standard Google Play application store with third-party substitutes the NCSC found to harbor sketchy, potentially malicious repackaging of common applications. The OnePlus 8T 5G—arguably, the best-known and most widely marketed phone of the three—was the only one to escape the NCSC's scrutiny without any red flags raised.' -- source: https://arstechnica.com/information-technology/2021/09/security-audit-raise… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Finally Shifting To 'Upstream First' Linux Kernel Approach For Android Features
by Peter Reutemann 23 Sep '21

23 Sep '21

'Phoronix reports: Google's Android had been notorious for all of its downstream patches carried by the mobile operating system as well as various vendor/device kernel trees while in recent years more of that code has been upstreamed. Google has also been shifting to the Android Generic Kernel Image (GKI) as the basis for all their product kernels to further reduce the fragmentation. Looking ahead, Google is now talking of an "upstream first" approach for pushing new kernel features into mainline Linux before deploying them on Android. Google's Todd Kjos talked today during Linux Plumbers Conference (LPC2021) around their Generic Kernel Image initiative. With Android 12 and their Linux 5.10 based GKI image they have further cut down the fragmentation to the extent that it's "nearly eliminated." With the Android 12 GKI, most of the vendor/OEM kernel features have now either been upstreamed into the Linux kernel, isolated to vendor modules/hooks, or merged into the Android Common Kernel. They are making good progress on the GKI front and also ensuring vendors adapt to the new approach to cut down on the kernel mess. But perhaps most exciting is their outlook for 2023 to 2024 for further reducing technical debt. They are going to pursue an "upstream first development model for new features" in making sure new code first lands into the mainline Linux kernel rather than aiming straight for lodging within the Android source tree.

Ubuntu 14.04 and 16.04 Each Get a Decade of Support from Canonical
by Peter Reutemann 22 Sep '21

22 Sep '21

'Canonical has announced that it is extending the life of Ubuntu 14.04 and 16.04 to a decade. BetaNews: In other words, Ubuntu 14.04 and 16.04 are getting longer Extended Security Maintenance (ESM) periods as Canonical pushes back their End of Life (EoL) dates. The former will now get security updates until 2024, while the latter will receive them until 2026. "This lifecycle extension enables organizations to balance their infrastructure upgrade costs, by giving them additional time to implement their upgrade plan. The prolonged Extended Security Maintenance (ESM) phase of Ubuntu 14.04 LTS and 16.04 LTS enables a secure and low-maintenance infrastructure with security updates and kernel livepatches provided by Canonical. The announcement represents a significant opportunity for the organizations currently implementing their transition to new applications and technologies," says Canonical.' -- source: https://linux.slashdot.org/story/21/09/21/1443254 That could help IoT devices to stay up to date for longer (at least OS-wise).

Over-Elaborate Shell Scripting
by Lawrence D'Oliveiro 21 Sep '21

21 Sep '21

When using a computer, laziness is a virtue. This is why we have command lines, to help automate the boring and repetitive tasks. This article <https://arstechnica.com/gadgets/2021/09/command-line-wizardry-part-two-vari…> continues the author’s intro to basic command-line concepts. But it repeats a failing I see all too often in shell scripting: doing complex parsing of the output of some command, when the command itself offers an option to produce something closer to the exact output you need. In this case, he is extracting the names of datasets from the “zfs list” command. And while I have zero experience with ZFS, I can look at documentation <https://docs.oracle.com/cd/E18752_01/html/819-5461/gazsu.html>, and discover that the command offers the “-o” option where you can select exactly that information you want it to output. It even has “-H” to simplify the output format right down, specifically to make it easier to parse. Sure, it’s fun to write code. But it can be even more fun to _avoid_ writing code. RTFM helps.

Linux Foundation Survey Shows Companies Desperate To Hire Open-Source Talent
by Peter Reutemann 21 Sep '21

21 Sep '21

'ZDNet reports: At the Open Source Summit in Seattle, The Linux Foundation, and edX, the leading massive open online course (MOOC) provider released the 2021 Open Source Jobs Report. In this survey of 200 technical hiring managers and 750 open-source pros, the organizations found more demand for top open-source workers than ever. On top of that, 92% of managers are having trouble finding enough talent and many of them are also having fits holding on to their existing senior open-source staffers. In short, if you've got open-source skills, whether you're a developer, a sysadmin, a DevOps expert, or a cloud-native pro, there's a good-paying job waiting for you out there. And, where before the Covid-19 pandemic, you might have been stuck with only jobs in your area, these days, thanks to the rise of working from home, you can still live at the old homestead instead of moving to Silicon Valley or Manhattan. On top of this 50% of employers surveyed stated they are increasing hires this year. The jobs are out there. The difficulty for companies is, as 92% of managers report, finding enough talent and hanging onto existing talent in the face of fierce competition. This is especially true for cloud-native application development and operations skills. Cloud-native tops the list of skills needed with over 46% of hiring managers looking for people with Kubernetes smarts. Indeed, for the first time in the survey's history, cloud and container technology skills are more in demand by hiring managers than Linux. Indeed, cloud and container skills rank far above Linux in this go around with 41% over 32%. [T]he survey also found that DevOps has become the standard method for developing software: Virtually all open-source professionals (88%) report using DevOps practices in their work, a 50% increase from three years ago. In other words, it's all DevOps all the time. "The survey also revealed that a majority of employers, 88%, now say that hiring certified professionals is a priority," the report adds. "That's an 87% increase in only three years, 57% in 2020, and 47% in 2018." Sadly, discrimination has also become more of an issue. "18% of open-source professionals now report they have been discriminated against or made to feel unwelcome in the community," the report says. "That's a 125% increase over the past three years."' -- source: https://news.slashdot.org/story/21/09/20/2031215 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Home Computing Pioneer Sir Clive Sinclair Dies Aged 81
by Peter Reutemann 20 Sep '21

20 Sep '21

'Sir Clive Sinclair, the man behind the Sinclair Spectrum and the first computer to retail for under a hundred dollars (the Sinclair ZX-81, A.K.A. The Timex/Sinclair 1000), died September 15 after battling a long illness. His daughter, Belinda, said he died at home in London on Thursday morning after a long illness. Sinclair invented the pocket calculator but was best known for popularising the home computer, bringing it to British high-street stores at relatively affordable prices. Many modern-day titans of the games industry got their start on one of his ZX models. For a certain generation of gamer, the computer of choice was either the ZX Spectrum 48K or its rival, the Commodore 64. Belinda Sinclair, 57, told the Guardian: "He was a rather amazing person. Of course, he was so clever and he was always interested in everything. My daughter and her husband are engineers so he'd be chatting engineering with them." He left school at 17 and worked for four years as a technical journalist to raise funds to found Sinclair Radionics.' -- source: https://news.slashdot.org/story/21/09/16/1936235 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
