"The laws of Australia prevail in Australia, I can assure you of that," [Malcolm Turnbull] said on Friday. "The laws of mathematics are very commendable, but the only law that applies in Australia is the law of Australia." <https://www.techdirt.com/articles/20170714/10385237789/aussie-prime-ministe…>

Munich Council: To Hell With Linux, We're Going Full Windows in 2020

by Peter Reutemann

'The German city of Munich, which received much popularity back in the day when it first ditched Microsoft's services in favor of open-source software, has now agreed to stop using Linux and switch back to Windows. If the decision is ratified by the full council in two weeks, Windows 10 will start rolling out across the city in 2020. From a report: A coalition of Social Democrats and Conservatives on the committee voted for the Windows migration last week, Social Democrat councillor Anne Hubner told The Register. Munich rose to fame in the open-source world for deciding to use Linux and LibreOffice to make the city independent from the claws of Microsoft. But the plan was never fully realised -- mail servers, for instance, eventually wound up migrating to Microsoft Exchange -- and in February the city council formally voted to end Linux migration and go back to Microsoft. Hubner said the city has struggled with LiMux adoption. "Users were unhappy and software essential for the public sector is mostly only available for Windows," she said. She estimated about half of the 800 or so total programs needed don't run on Linux and "many others need a lot of effort and workarounds." Hubner added, "in the past 15 years, much of our efforts were put into becoming independent from Microsoft," including spending "a lot of money looking for workarounds" but "those efforts eventually failed." A full council vote on Windows 10 2020 migration is set for November 23, Hubner said. However, the Social Democrats and Conservatives have a majority in the council, and the outcome is expected to be the same as in committee.' -- source: https://news.slashdot.org/story/17/11/13/1714220 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Today I Learned ...

by Lawrence D'Oliveiro

... what a “Layer 8 issue” is. You know how the ISO/OSI networking model has 7 layers, from the physical hardware up to the actual application that the user is using?

Roll On The Feudal Internet

by Lawrence D'Oliveiro

Quoted in <https://www.schneier.com/blog/archives/2017/12/amazons_door_lo.html>: The Key-compatible locks are made by Yale and Kwikset, yet don't work with those brands' own apps. They also can't connect with a home-security system or smart-home gadgets that work with Apple and Google software. And, of course, the lock can't be accessed by businesses other than Amazon. No Walmart, no UPS, no local dog-walking company. And so Amazon becomes a gatekeeper (literally) for access to your very home.

Does Apple Deliberately Slow Down Older IPhones?

by Lawrence D'Oliveiro

<https://arstechnica.com/gadgets/2017/12/iphones-slow-over-time-to-preserve-…>: ... the iPhone may throttle performance to preserve battery life or avoid unexpected shutdowns as the battery degrades. What an amazingly complicated solution to the problem. Let me offer a simpler one: why not just make it easier for Iphone users to replace their batteries?

All 500 of the World's Top 500 Supercomputers Are Running Linux

by Peter Reutemann

'Linux rules supercomputing. This day has been coming since 1998, when Linux first appeared on the TOP500 Supercomputer list. Today, it finally happened: All 500 of the world's fastest supercomputers are running Linux. The last two non-Linux systems, a pair of Chinese IBM POWER computers running AIX, dropped off the November 2017 TOP500 Supercomputer list. When the first TOP500 supercomputer list was compiled in June 1993, Linux was barely more than a toy. It hadn't even adopted Tux as its mascot yet. It didn't take long for Linux to start its march on supercomputing. >From when it first appeared on the TOP500 in 1998, Linux was on its way to the top. Before Linux took the lead, Unix was supercomputing's top operating system. Since 2003, the TOP500 was on its way to Linux domination. By 2004, Linux had taken the lead for good. This happened for two reasons: First, since most of the world's top supercomputers are research machines built for specialized tasks, each machine is a standalone project with unique characteristics and optimization requirements. To save costs, no one wants to develop a custom operating system for each of these systems. With Linux, however, research teams can easily modify and optimize Linux's open-source code to their one-off designs. The semiannual TOP500 Supercomputer List was released yesterday. It also shows that China now claims 202 systems within the TOP500, while the United States claims 143 systems.' -- source: https://linux.slashdot.org/story/17/11/14/2223227 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Fear And Loathing In Open-Source Clothing Design

by Lawrence D'Oliveiro

Seems the Valentina project, to create an open-source clothing design package, has split in two over the usual reason--disagreements among the project members <http://libregraphicsworld.org/blog/entry/valentina-seamly2d>. In that article, Alexandre Prokoudine tries to give an even-handed account of the saga, which can sometimes be quite difficult. The proprietary software in this field is extremely expensive--to the point where it becomes hard for clothing makers/designers to hire people who are familiar with using it. An alternative project, called SodaCAD <http://www.sodacad.org/>, takes a very different view: more direct control over the design (as I understand it), rather than trying to automatically fit a predefined design to given measurements, as Valentina does. It hasn’t seen much activity in over three years, though.

Undoing Data Anonymization Is Trivial

by Lawrence D'Oliveiro

Yet another demonstration <http://www.theregister.co.uk/2017/12/18/no_hack_needed_anonymisation_beaten…> of the seeming impossibility of publishing “anonymized” sets of personal data that cannot be traced back to specific individuals. The response of the Australian Government to a previous demonstration of such “de-anonymization” techniques was to seek laws to ban them.

Why Linux HDCP Isn't the End of the World

by Peter Reutemann

'"There is no reason for the open-source community to worry..." writes Daniel Stone, who heads the graphics team at open-source consultancy Collabora. mfilion quotes Collabora.com: Recently, Sean Paul from Google's ChromeOS team, submitted a patch series to enable HDCP support for the Intel display driver. HDCP is used to encrypt content over HDMI and DisplayPort links, which can only be decoded by trusted devices... However, if you already run your own code on a free device, HDCP is an irrelevance and does not reduce freedom in any way.... HDCP support is implemented almost entirely in the hardware. Rather than adding a mandatory encryption layer for content, the HDCP kernel support is dormant unless userspace explicitly requests an encrypted link. It then attempts to enable encryption in the hardware and informs userspace of the result. So there's the first out: if you don't want to use HDCP, then don't enable it! The kernel doesn't force anything on an unwilling userspace.... HDCP is only downstream facing: it allows your computer to trust that the device it has been plugged into is trusted by the HDCP certification authority, and nothing more. It does not reduce user freedom, or impose any additional limitations on device usage.' -- source: https://linux.slashdot.org/story/17/12/16/0320227 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Net Neutrality Repeal --- What It Means For NZ

by Rowan Schischka

<https://list.waikato.ac.nz/pipermail/wlug/2017-December/015504.html> So you are agreeing with me that USA has a problem of poor competition? In NZ if my provider gives me crap access to certain services, I have options, but in many places in the US they do not. Net Neutrality rules did not increase competition in USA, and I do not see how dropping regulations in US will affect NZ's access. Just like Internet censorship from the department of internal affairs is optional, so will any media business arrangement with our ISPs. I can choose one that does it and I can choose one that does not.
