Android 10 Go Edition Improves Speed and Security For Low-cost Phones
by Peter Reutemann 25 Sep '19

25 Sep '19

'Android Go has made smartphones more accessible by focusing on lower-cost devices, but it's frequently pokey and sometimes insecure -- not a great introduction to modern mobile tech. Google is aware of this, though, and it's tackling those issues head-on with its newly unveiled Android 10 Go edition. From a report: The scaled-back version of Android 10 puts a strong focus on speed, with faster and more memory-efficient app switching as well as launching that's 10 percent faster than in Android 9 Go. It should be more reliable, too. For some, data protection may be the real star of the show. Android 10 Go edition includes a new Adiantum encryption system that should secure data without affecting performance or requiring special hardware. You won't have to worry that your sensitive info is vulnerable simply because you bought an entry-level device.' -- source: https://mobile.slashdot.org/story/19/09/25/1648239 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/

Microsoft’s Cascadia Font Offers Ligatures For Programmers
by Lawrence D'Oliveiro 24 Sep '19

24 Sep '19

I just heard of this <https://devblogs.microsoft.com/commandline/cascadia-code/>, though it was apparently announced back in May. It has OpenType context-dependent substitutions for displaying “>=” as “≥”, “/=” as “≠” among others. Me? I just think it’s about time programming languages supported those Unicode characters directly.

Quantum Computers Are Analog Computers
by Lawrence D'Oliveiro 24 Sep '19

24 Sep '19

Google continues to experiment with quantum computing <https://arstechnica.com/science/2019/09/paper-leaks-showing-a-quantum-compu…>. This latest result (albeit preliminary) sounds impressive: But that seriously understates what's going on here. Every calculation that's done on a quantum computer will end up being a measurement of a quantum system. And in this case, there is simply no way to get that probability distribution using a classical computer. With this system, we can get it in under 10 minutes, and most of that time is spent in processing that doesn't involve the qubits. As the researchers put it, "To our knowledge, this experiment marks the first computation that can only be performed on a quantum processor." but it is still just reinforcing the point I made earlier <https://list.waikato.ac.nz/hyperkitty/list/wlug@list.waikato.ac.nz/thread/K…>, that quantum computers are just a reboot of the old idea of “analog” computers. These are able to do fast simulations of physical systems (in this case, a quantum probability distribution), to limited precision. But they continue to be useless for number-theoretic calculations, such as factoring large integers. Or code cracking.

EU Right To Be Forgotten Is For Europe Only
by Lawrence D'Oliveiro 24 Sep '19

24 Sep '19

The EU Court of Justice has ruled in favour of Google <https://arstechnica.com/tech-policy/2019/09/google-wins-case-as-court-rules…>, in saying that France’s claim that any “right to be forgotten” has to be implemented worldwide cannot apply. While it is true that, in an always-online connected world, the ease of bypassing regional bans makes a mockery of local laws, how do you reconcile the ability of one country to impose communication blocks on others with the idea of national sovereignty?

Linux Foundation Exec Believes Edge Computing Will Be More Important Than Cloud Computing
by Peter Reutemann 23 Sep '19

23 Sep '19

'Once upon a time, back when we all had mainframes and then servers in our offices, we had edge computing. Our compute power was literally down the hall. Then, along came the cloud, and all that changed. Computers were hundreds of miles but milliseconds away. Now, with the rise of IoT, 5G, and our never-satisfied need for speed, edge computing is coming back with a vengeance. Indeed, at his keynote at Open Networking Summit in Belgium, Arpit Joshipura, The Linux Foundation's general manager of networking, said "edge computing will overtake cloud computing" by 2025. When Joshipura is talking about edge computing, he means compute and storage resources that are five to 20 milliseconds away. He also means edge computing should be an open, interoperable framework. This framework should be independent of hardware, silicon, cloud, or operating system. Open-edge computing should also work with any edge-computing use case: Internet of Things (IoT) edge, a telecom edge, cloud edge, or enterprise edge, whatever, "Our goal here is to unify all of these." This is being done via LF Edge. This Linux Foundation organization seeks to bring all edge computing players under one umbrella with one technology. Its purpose is to create a software stack that unifies a fragmented edge market around a common, open vision for the future of the industry. To make this happen, Joshipura announced two more projects were being incorporated into LF Edge: Baetyl and Fledge.' -- source: https://slashdot.org/story/19/09/23/1722226 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/

GNU's Former Kernel Maintainer Shares 'A Reflection on the Departure of Richard Stallman'
by Peter Reutemann 22 Sep '19

22 Sep '19

'Thomas Bushnell, BSG, founded GNU's official kernel project, GNU Hurd, and maintained it from 1990 through 2003. This week on Medium he posted "a reflection on the departure of RMS." There has been some bad reporting, and that's a problem. While I have not waded through the entire email thread Selam G. has posted, my reaction was that RMS did not defend Epstein, and did not say that the victim in this case was acting voluntarily. But it's not the most important problem. It's not remotely close to being the most important problem. This was an own-goal for RMS. He has had plenty of opportunities to learn how to stfu when that's necessary. He's responsible for relying too much on people's careful reading of his note, but even that's not the problem. He thought that Marvin Minsky was being unfairly accused. Minsky was his friend for many many years, and I think he carries a lot of affection and loyalty for his memory. But Minsky is also dead, and there's plenty of time to discuss at leisure whatever questions there may be about his culpability. RMS treated the problem as being "let's make sure we don't criticize Minsky unfairly", when the problem was actually, "how can we come to terms with a history of MIT's institutional neglect of its responsibilities toward women and its apparent complicity with Epstein's crimes". While it is true we should not treat Minsky unfairly, it was not -- and is not -- a pressing concern, and by making it his concern, RMS signaled clearly that it was much more important to him than the question of the institution's patterns of problematic coddling of bad behavior. And, I think, some of those focusing themselves on careful parsing of RMS's words are falling into the same pitfall as he.... Minsky was RMS's protector for a long long time. He created the AI Lab, where I think RMS found the only happy home he ever knew. He kept the rest of the Institute at bay and insulated RMS from attack (as did other faculty that also had befriended RMS). I was around for most of the 90s, and I can confirm the unfortunate reality that RMS's behavior was a concern at the time, and that this protection was itself part of the problem... Bushnell also calls Stallman "a tragic figure. He is one of the most brilliant people I've met, who I have always thought desperately craved friendship and camaraderie, and seems to have less and less of it all the time. This is all his doing; nobody does it to him. But it's still very sad. As far as I can tell, he believes his entire life's work is a failure..." But Bushnell concludes that "It is time for the free software community to leave adolescence and move to adulthood, and this requires leaving childish tantrums, abusive language, and toxic environments behind."' -- source: https://news.slashdot.org/story/19/09/21/0253227 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/

Debian May Need To Re-Evaluate Its Interest In 'Init System Diversity'
by Peter Reutemann 22 Sep '19

22 Sep '19

'"Debian Project Leader Sam Hartman has shared his August 2019 notes where he outlines the frustrations and issues that have come up as a result of init system diversity with some developers still aiming to viably support systemd alternatives within Debian," reports Phoronix: Stemming from elogind being blocked from transitioning to testing and the lack of clarity into that, Hartman was pulled in to try to help mediate the matter and get to the bottom of the situation with a lack of cooperation between the elogind and systemd maintainers for Debian as well as the release team. Elogind is used by some distributions as an implementation of systemd's logind, well, outside of systemd as a standalone daemon. Elogind is one of the pieces to the puzzle for trying to maintain a modern, systemd-free Linux distribution. Various issues were raised that are trying to be worked through albeit many Debian developers face time limitations and other factors like emotional exhaustion. Hartman noted in his August notes, "I think we may be approaching a point where we need to poll the project -- to have a GR and ask ourselves how committed we are to the different parts of this init diversity discussion. Reaffirming our support for sysvinit and elogind would be one of the options in any such GR. If that option passed, we'd expect all the maintainers involved to work together or to appoint and empower people who could work on this issue. It would be fine for maintainers not to be involved so long as they did not block progress. And of course we would hold the discussions to the highest standards of respect."' -- source: https://linux.slashdot.org/story/19/09/21/042213 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/

Phrase Of The Week: “Tab Bankruptcy”
by Lawrence D'Oliveiro 21 Sep '19

21 Sep '19

What happens when you accumulate a growing bunch of open pages in your browser, meaning to look at them in the next few days, but never get around to it? Until you have so many tabs open, you realize you will never have time to check them out, so you abandon them all and start again? That’s called “declaring tab bankruptcy”. And here <https://github.com/jsvine/tab-bankrupter> is a Chrome extension that lets you do that, while preserving pinned tabs, but saves a record of all the tabs you’ve abandoned. So, you know, you can change your mind and come back to them later ... Then you’ll probably want another extension to let you declare saved-bankruptcy bankruptcy, where you wipe all your bankruptcy saves and start again ...

At The Open-Core Summit
by Lawrence D'Oliveiro 19 Sep '19

19 Sep '19

A bunch of companies <https://www.theregister.co.uk/2019/09/20/open_source_companies_cloud/> have met to share a common annoyance: that big corporations like Amazon, Google and Microsoft are able to profit from their open-source software without giving anything back. I’m not sure what you can do about it, though. Attempts to impose more restrictive conditions on licences seem to have backfired. The AGPL seems to have been the only one of these efforts to have any legs, and I’m doubtful it has really achieved much.
