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/

Mozilla Experiment: Set Default Search Engine to Bing for 1% of Firefox Users
by Peter Reutemann 20 Sep '21

20 Sep '21

'"Mozilla is running an experiment on 1% of the Firefox desktop population currently, which sets the default search engine to Bing in the web browser," reports Ghacks: [I]n most regions, it is Google Search. Mozilla and Google extended the search deal in 2020 for another three years. Google is paying Mozilla "between $400 and $450 million per year" so that its search engine is the default in Firefox in most regions. Google has been Firefox's default search engine since 2017, when Mozilla ended its search deal with Yahoo early. Firefox users may change the default search engine to one of the other engines that are included by default, or an engine that is not included but can be added... The study started on September 6 and it will run until early 2022, likely January 2022. About 1% of Firefox desktop users may notice that the default search engine is changed when the installation of Firefox is picked for the experiment. Tip: load about:studies in the Firefox address bar to list the studies that the browser us currently taking part in and has completed already. Firefox users who don't want to participate in studies can disable the preference "Allow Firefox to install and run studies" on about:preferences#privacy.

Is 2021 The Year of the Linux Desktop?
by Peter Reutemann 20 Sep '21

20 Sep '21

'"2021 Is the Year of Linux on the Desktop," writes PC Magazine. "No, really..." Walk into any school now, and you'll see millions of Linux machines. They're called Chromebooks. For a free project launched 30 years ago today by one man in his spare time, it's an amazing feat.... Linux found its real niche — not as a political statement about "free software," but as a practical way to enable capable, low-cost machines for millions... Chrome OS and Android are both based on the Linux kernel. They don't have the extra GNU software that distributions like Ubuntu have, but they're descended from Linus Torvalds' original work. Chromebooks are the fastest growing segment of the traditional PC market, according to Canalys. IDC points out that Canalys' estimates of 12 million Chromebooks shipped in Q1 2021 are only a fraction of the 63 million notebooks sold that quarter, but once again, they're where the growth is. Much of that is driven by schools, where Chromebooks dominate now. Schoolkids don't generally need a million apps' worth of generic computing power. They need inexpensive, rugged ways to log into Google Classroom. Linux came to the rescue, enabling cheap, light, easy-to-manage PCs that don't have the Swiss Army Knife cruft of Windows or the premium price of Macs... One great thing about open-source hacker projects is that they can be taken in unexpected directions. Linux isn't controlled, so it can adapt, Darwinian-style. It was a little scurrying mammal in the time of the dinosaurs, and then the mobile-computing asteroid hit. Linux could evolve. Windows couldn't. When you're building something that fits in your hand and has to sip battery, you can't just keep throwing processors and storage at it. Microsoft had a tough time adapting its monstrous megakernel OS to the new, tiny world. But *nix platforms thrive there: Android (based on Linux) and iOS. "Android and Chrome water down the Linux philosophy," the article argues, "but they are Linux..." Does this make any long-time geeks feel vindicated? In the original submission wiredog (Slashdot reader #43,288) looks back to 1995, remembering that "my first Linux was RedHat 2.0 in the beige box, running the 0.95(?) kernel and the F Virtual Window Manager... "It came with 2 books, a CD, and a boot floppy disk."' -- source: https://linux.slashdot.org/story/21/09/18/0050255 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/

Hi, I have parcels going missing. Does anyone know of technology to trace parcels?
by Michelle 18 Sep '21

18 Sep '21

It would presumably use GPS. It would involve a very small device put in the parcel that a thief would very possibly not even see when the parcel is scanned at customs. The icing on the cake would be if the route of the parcel was able to be recorded as evidence. I will give more details later like it going on for 3 months and involving parcels posted in NZ as well. But this is trial run email because I haven't posted in a long time and I want to make sure I am doing it right. I am hoping that if anyone replies to this that there is a convenient reply to button or link that I can reply back to. Oh well, after I send this email I want to go to the site and see if it has posted. Thanks for any help.

Some ne’er-do-wells are targeting users of the open-source paint app Krita, purporting to offer payment for advertising the app on their YouTube channels. But when they download the referenced media “asset” pack, they get a ransomware attack instead. <https://www.theregister.com/2021/09/14/krita_users_targeted_by_ransomware/>

UN Calls For Moratorium On AI That Threatens Human Rights
by Lawrence D'Oliveiro 16 Sep '21

16 Sep '21

The UN human rights office has released a report <https://www.aljazeera.com/economy/2021/9/15/warning-of-risk-un-rights-chief…> on the risks of AI technologies to human rights. Its head, Michelle Bachelet, wants safeguards against the abuse of such technologies before they get too widely deployed. Such technologies are increasingly being used for automated decision making by both companies and governments, in ways that can impact people’s lives in a major way: for example, to control access to social security benefits, health, education, or to identify criminal suspects for arrest. When mistakes are made in these areas, the consequences can be catastrophic for the individuals concerned. And the tendency to secrecy on the part of those using such technologies doesn’t help.

Travis CI flaw exposed secrets of thousands of open source projects
by Peter Reutemann 15 Sep '21

15 Sep '21

'A security flaw in Travis CI potentially exposed the secrets of thousands of open source projects that rely on the hosted continuous integration service. Travis CI is a software-testing solution used by over 900,000 open source projects and 600,000 users. A vulnerability in the tool made it possible for secure environment variables—signing keys, access credentials, and API tokens of all public open source projects—to be exfiltrated. Worse, the dev community is upset about the poor handling of the vulnerability disclosure process and the brief "security bulletin" it had to force out of Travis.' -- source: https://arstechnica.com/information-technology/2021/09/travis-ci-flaw-expos… 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/
