Linux Subsystem Files To Become Accessible via Windows File Explorer
by Peter Reutemann 19 Feb '19

19 Feb '19

'One of Windows Subsystem for Linux's more annoying tricks is it's hard to get at your Linux files from Windows. From a report: Oh, you can do it, but you take a real chance of ruining the files. To quote Microsoft, "DO NOT, under ANY circumstances, access, create, and/or modify files in your distro's filesystem using Windows apps, tools, scripts, consoles, etc." In the forthcoming Windows 10 April 2019 Update, aka Windows 10 19H1, this Linux file problem will finally be fixed. According to Craig Loewen, a Microsoft programming manger working on Windows Subsystem for Linux (WSL), "The next Windows update is coming soon and we're bringing exciting new updates to WSL with it! These include accessing the Linux file system from Windows, and improvements to how you manage and configure your distros in the command line."' -- source: https://linux.slashdot.org/story/19/02/19/2119226 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/

How Not To Build A PC, And How Not To Respond To Those Criticizing You For It
by Lawrence D'Oliveiro 19 Feb '19

19 Feb '19

About four months ago, The Verge posted a video on its YouTube channel explaining the basics of building your own PC. Unfortunately, the video was full of mistakes, some small, some potentially more troublesome. Naturally this was pointed out in the comments. Also several other more techie-oriented channels responded with their own critique videos, some quite scathing. Rather than admit its mistake, the company decided to simply block comments for that video, and eventually take it down altogether. (Though not before it had accumulated a few thousand downvotes.) Now, within the last week or so, it has suddenly decided to go after those critique videos, and force them to be taken down on the basis of copyright infringement, because they contain extracts from the original item. Extracts which, under US fair use law, it was perfectly legal for them to include. Naturally, these heavy-handed attempts at censorship provoked a great deal of anger and protest, and the company has had to relent. If it was trying to downplay any lingering evidence of its previous embarrassment, this was absolutely not the way to do it. The phrase “Streisand Effect” immediately comes to mind, where an attempt by the eponymous celebrity to suppress pictures of the outside of her home, taken from public property, only caused them to be spread more widely. <https://www.youtube.com/results?search_query=the+verge+pc+build+takedown> Origin of the Streisand Effect: <https://www.techdirt.com/articles/20030624/1231228.shtml>

Inside the DNSpionage hacks that hijack domains at an unprecedented scale
by Peter Reutemann 18 Feb '19

18 Feb '19

'Since the beginning of the year, the US government and private security companies have been warning of a sophisticated wave of attacks that’s hijacking domains belonging to multiple governments and private companies at an unprecedented scale. On Monday, a detailed report provided new details that helped explain how and why the widespread DNS hijackings allowed the attackers to siphon huge numbers of email and other login credentials. The article, published by KrebsOnSecurity reporter Brian Krebs, said that, over the past few months, the attackers behind the so-called DNSpionage campaign have compromised key components of DNS infrastructure for more than 50 Middle Eastern companies and government agencies. Monday’s article goes on to report that the attackers, who are believed to be based in Iran, also took control of domains belonging to two highly influential Western services—the Netnod Internet Exchange in Sweden and the Packet Clearing House in Northern California. With control of the domains, the hackers were able to generate valid TLS certificates that allowed them to launch man-in-the-middle attacks that intercepted sensitive credentials and other data.' -- source: https://arstechnica.com/information-technology/2019/02/inside-the-dnspionag… 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/

Re: [wlug] RNZ Mediawatch--Geeks’ Gathering Goes Under The Radar
by Ian Stewart 17 Feb '19

17 Feb '19

In the Mediawatch Radio NZ broadcast Geeks' gathering goes under the media radar, David Lane, president of the NZ Open Source Society<https://nzoss.org.nz/>, stated that all the talks [given at the Linux Conference in Christchurch] are all available for anyone to watch on youtube right now. The following link takes you to the youtube summary page with the links to videos of all the presentations... https://www.youtube.com/user/linuxconfau2019/videos There are over 160 videos, and the average video is about 40 minutes, so there is over one hundred hours of viewing. An alternative to using youtube is to go to... http://mirror.linux.org.au/pub/linux.conf.au/2019/ ... select the presentation room, the day of the week, and the presentation can be downloaded in either mp4 or webm format. It's good to see in the list of credits<http://mirror.linux.org.au/pub/linux.conf.au/2019/README.md> for the core team that helped to make the videos there is a Waikato man that we haven't seen for a while, William McKee. cheers, Ian.

RNZ Mediawatch--Geeks’ Gathering Goes Under The Radar
by Lawrence D'Oliveiro 15 Feb '19

15 Feb '19

Did you know that the annual linux.conf.au gathering was held in Christchurch last month? And that Linus Torvalds was there, wandering around the Canterbury University campus? Neither did I. Radio New Zealand’s Mediawatch program from a couple of weeks ago goes into the reasons why there was no media coverage of the event. Partly they might have been put off by some of the more esoteric and technical subjects being discussed. But in among them were some topics that should be considered more relevant to the “mainstream”, such as how automation could be doing away with many jobs being done by humans, leaving only the low-paying ones. The item includes an interview with NZOSS president Dave Lane, in which he incidentally mentions that Radio New Zealand’s online presence is built on Open Source, and that stuff.co.nz was, until recently, doing the same, and was also the one part of the Fairfax online media empire that was making money. Until that system was replaced with one based on expensive and proprietary Adobe products. And now they are not making nearly as much money. Coincidence? You be the judge. <https://www.radionz.co.nz/national/programmes/mediawatch/audio/2018680533/g…> By the way, it seems they have stopped making Ogg versions of items like these available for playback or download -- the links for the above one are only for an MP3 version. Also, I don’t agree that the distinction between “artificial intelligence” and “machine learning” is that clear-cut. I did a graduate course on AI back in the day, and it was already a pretty fuzzy concept back then. Except for one quite concise, mathematically-based definition I came across that appealed to me: “solving NP problems in polynomial time”.

Open Source Project Aims To Make Ubuntu Usable on Arm-Powered Windows Laptops
by Peter Reutemann 14 Feb '19

14 Feb '19

'A group of programmers and device hackers are working to bring proper support for Ubuntu to Arm-powered Windows laptops, starting with first-generation Snapdragon 835 systems, like the HP Envy x2 and Asus NovaGo. From a report: The aarch64-laptops project provides prebuilt images for the aforementioned notebook PCs, as well as the Lenovo Miix 630. Although Ubuntu and other Linux distributions support aarch64 (ARMv8) by default, various obstacles including the design and configuration of Qualcomm Snapdragon processors make these default images not practically usable. The aarch64-laptops project developers are aiming to address these difficulties, though work is still ongoing. Presently, the TouchPad does not work properly on the Asus, with all three lacking proper support for on-board storage and Wi-Fi, which rely on UFS support. According to their documentation, this is being worked on upstream.' -- source: https://news.slashdot.org/story/19/02/14/1448221 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/
