Mozilla Eyes Decentralized Web-Based Videoconferencing Platform 'Meething'
by Peter Reutemann 08 Jun '20

08 Jun '20

'Last month Techcrunch reported that Mozilla had gone "full incubator" by holding a startup lab called Fix the Internet, followed by "a formal program dangling $75,000 investments in front of early-stage companies..." Fix the Internet had many key themes, including collaboration and decentralization (as well as user-controlled data and privacy-protecting social networks). That event "drew the interest of some 1,500 people in 520 projects, and 25 were chosen to receive the full package and stipend during the development of their minimum viable product (MVP). Below that, as far as pecuniary commitment goes, is the 'MVP Lab,' similar to the spring program but offering a total of $16,000 per team." And one of those MVP Lab teams is Meething, a new video conferencing and collaboration platform from the innovation lab ERA. Meething "aims to be more secure than existing video conferencing tools and run on a decentralized database engine and leverage peer-to-peer networking" according to ZDNet. In their video interview with CEO Mark Nadal, he outlined the following selling points: - Browser based video conferencing gives customers better options for security as well as branding. - Open source architecture is a win and the peer-to-peer networking is more efficient on compute costs. - Meething doesn't require downloads or apps that increase the security attack surface. The total addressable market for video conferencing is large and can support multiple players. Their press release quotes Mark Mayo, a former Chief Product Officer at Mozilla who served as Meething's mentor, arguing that video conferencing on the web "has long promised to enable a whole new world of online collaboration. Frankly, it hasn't delivered. It's been way too hard to build cool products with video and Meething aims to be the zero-barrier-to-entry platform that realizes this future. Soon, video conferencing won't suck!"' -- source: https://tech.slashdot.org/story/20/06/07/1739228 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 SpaceX Uses Linux, Chromium, C++ and Open Source Libraries
by Peter Reutemann 07 Jun '20

07 Jun '20

'Long-time Slashdot reader mrflash818 ("Linux geek since 1999") shared a ZDNet article pointing out that SpaceX's Falcon 9 rocket has an onboard operating system that's "a stripped-down Linux running on three ordinary dual-core x86 processors. The flight software itself runs separately on each processor and is written in C/C++." Interestingly, back in 2018 a Slashdot headline asked whether C++ was "a really terrible language," and Elon Musk replied on Twitter with his single-word answer. "Yes." ZDNet points out that "ordinary" processors are often needed because of the multi-year development time for the spacecraft they power. Their article notes that the International Space Station actually runs on 1988-vintage 20 MHz Intel 80386SX CPUs: Of course, while those ancient chips work for the station's command and control multiplexer/demultiplexer, they're not much good for anything else. For ordinary day-in and day-out work, astronauts use HP ZBook 15s running Debian Linux, Scientific Linux, and Windows 10. The Linux systems act as remote terminals to the control multiplexer/demultiplexer, while the Windows systems are used for email, the web, and fun. Usually, though, chips that go into space aren't ordinary chips. CPUs that stay in space must be radiation-hardened. Otherwise, they tend to fail due to the effects of ionizing radiation and cosmic rays. These customized processors undergo years of design work and then more years of testing before they are certified for spaceflight. For instance, NASA expects its next-generation, general-purpose processor, an ARM A53 variant you may know from the Raspberry Pi 3, to be ready to run in 2021... The Dragon spacecraft's touchscreen interface is rendered using Chromium and JavaScript. If something were to go wrong with the interface, the astronauts have physical buttons to control the spacecraft. Today the SpaceX software team answered questions on Reddit, revealing they use Chromium with a reactive library developed in-house, and that "All of our on-board computers either run Linux (with the PREEMPT_RT patch) or are microcontrollers that run bare-metal code...." Later they emphasized that for the Falcon 9 and Dragon software, "All of the application-level autonomous software is written in C++. We generally use object oriented programming techniques from C++, although we like to keep things as simple as possible. "We do use open source libraries, primarily the standard C++ library, plus some others. However, we limit our use of open source libraries to only extremely high quality ones, and often will opt to develop our own libraries when it is feasible so that we can control the code quality ourselves."' -- source: https://science.slashdot.org/story/20/06/06/2023249 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/

Linux Mint Dumps Ubuntu Snap
by Peter Reutemann 07 Jun '20

07 Jun '20

'ZDNet reports: Mint's programmers, led by lead developer, Clement "Clem" Lefebvre, has dropped support for Ubuntu's Snap software packing system. [...] So, what's not to like? Well, a lot, thinks Clem. As he wrote in July 2019, the idea is fine: "When snap was announced it was supposed to be a solution, not a problem. It was supposed to make it possible to run newer apps on top of older libraries and to let third-party editors publish their software easily towards multiple distributions, just like Flatpak and AppImage." But, he said, "What we didn't want it to be was for Canonical to control the distribution of software between distributions and third-party editors, to prevent direct distribution from editors, to make it so software worked better in Ubuntu than anywhere else and to make its store a requirement." Clem was worried then that Canonical was moving in that direction because: "Ubuntu is planning to replace the Chromium [Google's open-source browser and foundation for Chrome] repository package with an empty package, which installs the Chromium snap. In other words, as you install APT [Debian's program for installing and managing DEB files] updates, Snap becomes a requirement for you to continue to use Chromium and installs itself behind your back. This breaks one of the major worries many people had when Snap was announced and a promise from its developers that it would never replace APT. A self-installing Snap Store which overwrites part of our APT package base is a complete NO-NO. It's something we have to stop and it could mean the end of Chromium updates and access to the snap store in Linux Mint." Fast forward to now, and that's still the case with Chromium, and Clem has had enough: "In the Ubuntu 20.04 package base, the Chromium package is indeed empty and acting, without your consent, as a backdoor by connecting your computer to the Ubuntu Store. Applications in this store cannot be patched, or pinned. You can't audit them, hold them, modify them, or even point snap to a different store. You've as much empowerment with this as if you were using proprietary software, i.e. none. This is in effect similar to a commercial proprietary solution, but with two major differences: It runs as root, and it installs itself without asking you."

Lenovo Will Pre-load Ubuntu and Red Hat on All Its Workstations
by Peter Reutemann 07 Jun '20

07 Jun '20

'TechRepublic calls it "a tectonic shift in the landscape... a massive company showing serious support for both Ubuntu Linux and Red Hat Enterprise Linux." Forbes reports: Beginning this month, Lenovo will certify its ThinkStation PCs and ThinkPad P Series laptops for both Ubuntu LTS and Red Hat Enterprise Linux. Every single model, every single configuration across the entire workstation portfolio. [ZDNet adds that the two Linux distros will also be preloaded.] And it doesn't end there. "Going beyond the box, this also includes full web support, dedicated Linux forums, configuration guidance and more," says Rob Herman, General Manager, Executive Director Workstation & Client AI Group at Lenovo. We're not talking about just hardware certification, either. Lenovo will offer both Red Hat Enterprise Linux and Ubuntu LTS distributions pre-installed... "What's more, Lenovo will also upstream device drivers directly to the Linux kernel, to help maintain stability and compatibility throughout the life of the workstation," says Herman. Lenovo and Fedora are already working together to enable fingerprint sensor support on select ThinkPads, and send that support upstream to benefit all Linux distributions (including firmware being available through LVFS). When I spoke to Mark Pearson, the Senior Linux Software Engineer even mentioned porting certain Windows-only PC management tools to Linux to aid in the overall effort. TechRepublic notes the news "comes on the heels of a number of new Linux desktop support news. This year we've seen the rise of Purism, Tuxedo Computers, Pine64, Juno Computers, Vikings, Dell's continued support with the XPS Dev edition laptop and the Precision line, and now Lenovo." They also argue for continued support for the smaller vendors of Linux hardware. "Companies like System76 are a big reason why desktop Linux continued climbing up that steep mountain called 'Acceptance.'" But their article concludes that "No matter which path you take, you now (as a Linux user) have more options."' -- source: https://linux.slashdot.org/story/20/06/06/0113250 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/

Will The Transition To IPv6 Take 5 to 10 Years?
by Peter Reutemann 07 Jun '20

07 Jun '20

'The Register: IPv4 is here to stay with us for a good few years yet, reckons the the Réseaux IP Européens Network Coordination Centre's (RIPE NCC) public policy manager, eight years after IPv6 was supposed to replace it. Marco Hogewoning, public policy for the Amsterdam, Netherlands-based European regional internet registry, told The Register that despite the best efforts of IPv6 proponents over the last eight years, it might take "five to 10 years" before the world starts to truly abandon the IPv4 address space. IPv6 was first defined in 1996, but with Friday marking the 8th anniversary of (the second) IPv6 "Launch" Day, RIPE NCC was keen to talk up the tech, whose chief benefit is that it provides a much greater pile of internet addresses for all the stuff humanity has dumped online in the last few decades...Musing that "little pockets of IPv4" and some government services hosted on IPv4 are two of the things holding the world back, Hogewoning told The Register: "It's impossible for me to file my taxes over IPv6. As much as I want, I can't get rid of IPv4 in the end because I need to file my taxes. That's a dialogue we try to have with the governments... It's an important step to go to, enabling IPv6 [instead of] IPv4 to make sure we don't force people to have that backwards compatibility."' -- source: https://tech.slashdot.org/story/20/06/06/0245248 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/

one week of arch
by Peter Reutemann 07 Jun '20

07 Jun '20

Hi everyone At last month's meeting, we also had a look at Manjaro, an Arch-based Linux distribution: https://www.meetup.com/WaikatoLinuxUsersGroup/events/266792009/ While preparing for the presentation, I played around with Manjaro and quite liked the arch package manager "pacman". Since then, Angus came across EndeavourOS, another Arch Linux distribution, which is a bit more up-to-date than Manjaro: https://endeavouros.com/ So, last weekend, I decided to bite the bullet and upgrade the aging LinuxMint 18.3 installation on my laptop at home. The EndeavourOS installer seemed less polished (showing lots of Space Shuttle Endeavour related imagery) than the likes of Mint or Ubuntu, but it did the job. Always glad that my home directory is on a separate partition. Makes the installation so much easier... :-) I've been using it now for a week and I must say, I quite like it. The MATE desktop, in contrast to Linux Mint, is far less polished, but it works absolutely fine. It feels really, really snappy (and that on a spinning drive!) and it doesn't seem to suffer from the same performance degradation over time like my old Mint installation did: as the days went by, the login screen would take longer and longer to show up after resuming from sleep, the Caja file browser would take longer to start up and everything just felt more and more sluggish. Last night, I flashed an old Samsung S4 with LineageOS (Android 9) and I didn't have to resort to compiling Heimdall myself, the Arch repositories already had packages built on the latest code from the repository. Nice! Only problem so far are the proprietary Brother printer drivers. Haven't been able to get printing working yet (the package for the printer in the arch repositories didn't do anything). Something to figure out on a rainy day... Anyway, looks like I'm sort of an Arch convert now. ;-) 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/

Windows 10 Is Hostile To Open Source
by Lawrence D'Oliveiro 06 Jun '20

06 Jun '20

From <https://www.theregister.com/2020/06/05/windows_10_microsoft_defender_smarts…>: A developer of a Windows utility has protested that "Microsoft Defender SmartScreen is hurting independent developers" because of the number of warnings and obstacles placed in front of users who download installers that are not signed or sufficiently well known. In the absence of a “Let’s Encrypt” equivalent for them, code-signing certificates cost money. And on top of that, SmartScreen’s warnings will not go away until that certificate has built up some (unspecified) minimum level of “reputation”. Because of this, many projects, like Ardour and Inkscape, don’t bother with signing, and rely on their users to negotiate the obstacle course of download and installation warnings.

Follow-up to the EFF .ORG petition
by Ian Stewart 06 Jun '20

06 Jun '20

You may remember, from over a month ago, there was circulation on WLUG email of a request to sign a petition<https://act.eff.org/action/help-stop-the-sale-of-public-interest-registry-t…> of Electronic Frontier Foundation to "Help Stop the Sale of Public Interest Registry to a Private Equity Firm"... "This month [November 2019] it was suddenly announced that the nonprofit that owns the .ORG domain registry was planning to sell it to a private equity firm, Ethos Capital. This could impact the millions of individuals and organizations that have a .ORG website, subjecting them to potential censorship and leaving the door open for price increases on domain registration and renewals." You may be wondering what happened. I've just looked at the wikipedia entry for .ORG, and it contains the following paragraph based on this article from the The Verge<https://www.theverge.com/2020/4/30/21241946/icann-dot-org-isoc-ethos-capita…>: "In November 2019, the Public Interest Registry (PIR) was to be sold by the Internet Society to shell company Ethos Capital for US$1.135 billion. The PIR also announced it would abandon its non-profit status to become a B Corporation. However, this move was criticized by non-profits and various digital rights groups on concerns that Ethos Capital, a private equity firm, would raise fees or censor the domain. The sale was blocked by Internet Corporation for Assigned Names and Numbers (ICANN) in April 2020 on the basis that transfer of control of the domain to the private equity firm would create "unacceptable uncertainty" for non-profits that relied on the .org domain." While Wikipedia's entry on .ORG<https://en.wikipedia.org/wiki/.org> has a brief history section, more details can be found at Wikipedias Public Interest Registry webpage<https://en.wikipedia.org/wiki/Public_Interest_Registry>. In case you find its TL;DR here are some snippets... the Internet Society proposed creating the Public Interest Registry as a separate 501(c)3 non-profit to manage .ORG when the Public Interest Registry was established, “our aim was to promote the non-commercial use of the internet" Public Interest Registry released an open letter on 1 May 2019, stating, “The .ORG Community always is considered in every decision we make here at Public Interest Registry. Rest assured, we will not raise prices unreasonably. In fact, we currently have no specific plans for any price increases for .ORG.” On 13 May 2019, ICANN announced that they would remove the price cap on .ORG registrations. ...former ICANN CEO Fadi Chehadé registered the domain name EthosCapital.com. On 14 May 2019, Ethos Capital was incorporated in Delaware On 13 November 2019 the Internet Society announced that it was divesting of the Public Interest Registry, and that Ethos Capital would be acquiring its assets Ethos Capital stated on their website, "Our plan is to live within the spirit of historic practice when it comes to pricing," which they later clarified to mean raising prices by an average of 10% per year. People who came out in opposition to the sale included Tim Berners-Lee... On 29 November 2019, it was revealed that the purchase price is $1.135 billion. On 30 April 2020, the ICANN Board, saying it was "the right thing to do," withheld its consent to the transfer of control of the Public Internet Registry to Ethos Capital, effectively killing the proposed deal. In Summary The .ORG remains in the hands of the "Public Interest Registry" which seems to sometimes get called the "Public Internet Registry"? The "Public Interest Registry" pir.org link takes you to https://thenew.org/org-people/ where, among other things, you can download the PIR 2018 Annual Report<https://thenew.org/app/uploads/2019/09/PIR-2018-Annual-Report.pdf> or their 2018 Form 990<https://thenew.org/app/uploads/2019/09/PIR-2017_2018-990.zip> "Return of Organization Exempt From Tax". For 2018 you will see their total revenue was $93 million. cheers, Ian.

Linux not Windows: Why Munich is shifting back from Microsoft to open source – again
by Peter Reutemann 05 Jun '20

05 Jun '20

'In a notable U-turn for the city, newly elected politicians in Munich have decided that its administration needs to use open-source software, instead of proprietary products like Microsoft Office. "Where it is technologically and financially possible, the city will put emphasis on open standards and free open-source licensed software," a new coalition agreement negotiated between the recently elected Green party and the Social Democrats says. The agreement was finalized Sunday and the parties will be in power until 2026. "We will adhere to the principle of 'public money, public code'. That means that as long as there is no confidential or personal data involved, the source code of the city's software will also be made public," the agreement states.' -- source: https://www.zdnet.com/article/linux-not-windows-why-munich-is-shifting-back… 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/

Signal Launches Face-Blurring Tool as US Protesters Embrace Encrypted Messaging
by Peter Reutemann 05 Jun '20

05 Jun '20

'Law enforcement officials across the U.S. have already revealed that they will leverage facial recognition technology to retroactively target protesters following the killing of George Floyd, with police asking the public for footage and photos. Against this backdrop, Signal is introducing a new feature that can automatically obfuscate faces shared within the encrypted messaging app, as the company says it's "working hard to keep up with the increased traffic" from protesters. From a report: Moving forward, Signal users will be able to activate a feature in the main photo editing toolbox that will automatically blur all faces it identifies in an image. As with many automated computer vision tools, Signal doesn't claim that its face-blurring smarts are 100% effective. It may not identify all faces in a photo, which is why users can manually obscure faces by drawing the blur brush across each face with their finger.' -- source: https://it.slashdot.org/story/20/06/04/1621201 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/
