Should Windows Move To A Linux Kernel?
by Lawrence D'Oliveiro 16 Oct '20

16 Oct '20

An engineer at Canonical has poured cold water <https://www.theregister.com/2020/10/15/even_2020_cannot_bring_forth/> over the suggestion by Eric Raymond that Microsoft might move to substituting a Linux kernel over its own in the Windows OS. Sure, the idea seems complicated and expensive, and very likely troublesome, too. But since when have Windows upgrades not been troublesome? Even updates between different versions of what is ostensibly all the same OS, Windows 10, have been far from smooth lately. Attempting the level of compatibility needed for every Win32 API and syscall would be a huge undertaking. Consider that the WINE folks have already provided a usable fraction of this, with resources that are only a drop in the bucket compared to those available to Microsoft. And as for the vast array of drivers enjoyed by the NT kernel, Barnes reckoned that shunting them into Linux would cost millions. Sure. But would it cost as much as having to continue maintaining them? Particularly since most of those drivers would not be needed, because Linux already has its own native ones. Furthermore, rebasing Windows on Linux could have the ironic effect of stifling competition should a kernel monoculture take hold. Interesting to discuss this use of the term “monoculture”. Linux is already adaptable to a wider range of platforms and applications than Windows can manage. This in spite of the fact that the Windows NT kernel has been fragmented into a number of different versions, including about 5 or 6 different ones for ARM, with little or no compatibility between them. Linux is able to manager better interoperability than that, even between versions for entirely different architectures.

Google and Intel Warn of High-Severity Bluetooth Security Bug In Linux
by Peter Reutemann 15 Oct '20

15 Oct '20

'An anonymous reader quotes a report from Ars Technica: Google and Intel are warning of a high-severity Bluetooth flaw in all but the most recent version of the Linux Kernel. While a Google researcher said the bug allows seamless code execution by attackers within Bluetooth range, Intel is characterizing the flaw as providing an escalation of privileges or the disclosure of information. The flaw resides in BlueZ, the software stack that by default implements all Bluetooth core protocols and layers for Linux. Besides Linux laptops, it's used in many consumer or industrial Internet-of-things devices. It works with Linux versions 2.4.6 and later. So far, little is known about BleedingTooth, the name given by Google engineer Andy Nguyen, who said that a blog post will be published "soon." A Twitter thread and a YouTube video provide the most detail and give the impression that the bug provides a reliable way for nearby attackers to execute malicious code of their choice on vulnerable Linux devices that use BlueZ for Bluetooth. Intel, meanwhile, has issued this bare-bones advisory that categorizes the flaw as privilege-escalation or information-disclosure vulnerability. The advisory assigned a severity score of 8.3 out of a possible 10 to CVE-2020-12351, one of three distinct bugs that comprise BleedingTooth. "Potential security vulnerabilities in BlueZ may allow escalation of privilege or information disclosure," the advisory states. "BlueZ is releasing Linux kernel fixes to address these potential vulnerabilities." Intel, which is a primary contributor to the BlueZ open source project, said that the most effective way to patch the vulnerabilities is to update to Linux kernel version 5.9, which was published on Sunday. Those who can't upgrade to version 5.9 can install a series of kernel patches the advisory links to. Maintainers of BlueZ didn't immediately respond to emails asking for additional details about this vulnerability. Ars Technica points out that since BleedingTooth requires proximity to a vulnerable device, there's not much reason for people to worry about this vulnerability. "It also requires highly specialized knowledge and works on only a tiny fraction of the world's Bluetooth devices," it adds.' -- source: https://it.slashdot.org/story/20/10/15/0043232 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Zoom To Roll Out End-to-End Encrypted (E2EE) Calls
by Peter Reutemann 15 Oct '20

15 Oct '20

'Video conferencing platform Zoom announced today plans to roll out end-to-end encryption (E2EE) capabilities starting next week. From a report: E2EE will allow Zoom users to generate individual encryption keys that will be used to encrypt voice or video calls between them and other conference participants. These keys will be stored locally and will not be shared with Zoom servers, meaning the software company won't be able to access or intercept any ongoing E2EE meetings. Support for E2EE calls will first be part of Zoom clients to be released next week. To use the new feature, users must update theri clients next week and enable support for E2EE calls at the account level. This green shield will contain a lock if E2EE is active. If the lock is absent, Zoom will use its default AES 256-bit GCM encryption scheme, which the company uses to secure current communications, but which the company can also intercept.' -- source: https://yro.slashdot.org/story/20/10/14/1722237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

WordPress Versus Jamstack
by Lawrence D'Oliveiro 14 Oct '20

14 Oct '20

Welcome to a new buzzword: “Jamstack”, which stands for “JavaScript, APIs and HTML Markup”. Or, in other words, websites made up of static pages, with all the dynamism implemented by JavaScript running on the browser. Hmm, maybe not quite all--that “APIs” part does still imply server-side dynamism of some sort. Seems the founder of WordPress is less than keen on the idea. WordPress, of course, is built very heavily around PHP code doing dynamic things (like reading and writing databases) server-side. Maybe the difference between the two is more one of degree and centralization rather than anything hard-and-fast. <https://www.theregister.com/2020/10/13/wordpress_matt_vs_netlify_matt/>

Notepad++/Windows -> Notepadqq/Linux
by Peter Reutemann 13 Oct '20

13 Oct '20

Hi everyone Today, I was looking for a (graphical) text editor that could search through a directory structure and replace a particular string in lots of config files. Just using find in conjunction with sed wasn't gonna cut it, as I needed to inspect each individual file first (but then do a single subversion commit covering all the files). While searching on alternativeto.net for an alternative to Notepad++, using this URL: https://alternativeto.net/software/notepad-plus-plus/ I came across Notepadqq, which had the desired functionality: https://notepadqq.com/ Just like Notepad++, it also has syntax highlighting for lots of different file types. It's great to have such a wide variety of editors out there! :-) Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux 5.9 Boosts CPU Performance With FSGSBASE Support
by Peter Reutemann 13 Oct '20

13 Oct '20

'FSGSBASE support in Linux "has the possibility of helping Intel/AMD CPU performance especially in areas like context switching that had been hurt badly by Spectre/Meltdown and other CPU vulnerability mitigations largely on the Intel side," Phoronix wrote back in August. As it started its journey into the kernel, they provided a preview on August 10: The FSGSBASE support that was finally mainlined a few days ago for Linux 5.9 is off to providing a nice performance boost for both Intel and AMD systems... FSGSBASE support for the Linux kernel has been around a half-decade in the making and finally carried over the finish line by one of Microsoft's Linux kernel engineers... FSGSBASE particularly helps out context switching heavy workloads like I/O and allowing user-space software to write to the x86_64 GSBASE without kernel interaction. That in turn has been of interest to Java and others...On Linux 5.9 where FSGSBASE is finally mainlined, it's enabled by default on supported CPUs. FSGSBASE can be disabled at kernel boot time via the "nofsgsbase" kernel option. Today on the Linux kernel mailing list, Linus Torvalds announced the release of Linux 5.9: Ok, so I'll be honest - I had hoped for quite a bit fewer changes this last week, but at the same time there doesn't really seem to be anything particularly scary in here. It's just more commits and more lines changed than I would have wished for. And Phoronix reported: Linux 5.9 has a number of exciting improvements including initial support for upcoming Radeon RX 6000 "RDNA 2" graphics cards, initial Intel Rocket Lake graphics, NVMe zoned namespaces (ZNS) support, various storage improvements, IBM's initial work on POWER10 CPU bring-up, the FSGSBASE instruction is now used, 32-bit x86 Clang build support, and more. See our Linux 5.9 feature overview for the whole scoop on the many changes to see with this kernel.' -- source: https://linux.slashdot.org/story/20/10/12/0029215 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Apple's T2 Security Chip Has an Unfixable Flaw
by Peter Reutemann 13 Oct '20

13 Oct '20

'A recently released tool is letting anyone exploit an unusual Mac vulnerability to bypass Apple's trusted T2 security chip and gain deep system access. The flaw is one researchers have also been using for more than a year to jailbreak older models of iPhones. But the fact that the T2 chip is vulnerable in the same way creates a new host of potential threats. Worst of all, while Apple may be able to slow down potential hackers, the flaw is ultimately unfixable in every Mac that has a T2 inside. From a report: In general, the jailbreak community haven't paid as much attention to macOS and OS X as it has iOS, because they don't have the same restrictions and walled gardens that are built into Apple's mobile ecosystem. But the T2 chip, launched in 2017, created some limitations and mysteries. Apple added the chip as a trusted mechanism for securing high-value features like encrypted data storage, Touch ID, and Activation Lock, which works with Apple's "Find My" services. But the T2 also contains a vulnerability, known as Checkm8, that jailbreakers have already been exploiting in Apple's A5 through A11 (2011 to 2017) mobile chipsets. Now Checkra1n, the same group that developed the tool for iOS, has released support for T2 bypass. On Macs, the jailbreak allows researchers to probe the T2 chip and explore its security features. It can even be used to run Linux on the T2 or play Doom on a MacBook Pro's Touch Bar. The jailbreak could also be weaponized by malicious hackers, though, to disable macOS security features like System Integrity Protection and Secure Boot and install malware. Combined with another T2 vulnerability that was publicly disclosed in July by the Chinese security research and jailbreaking group Pangu Team, the jailbreak could also potentially be used to obtain FileVault encryption keys and to decrypt user data. The vulnerability is unpatchable, because the flaw is in low-level, unchangeable code for hardware. "The T2 is meant to be this little secure black box in Macs -- a computer inside your computer, handling things like Lost Mode enforcement, integrity checking, and other privileged duties," says Will Strafach, a longtime iOS researcher and creator of the Guardian Firewall app for iOS. "So the significance is that this chip was supposed to be harder to compromise -- but now it's been done."' -- source: https://apple.slashdot.org/story/20/10/12/1854254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Five-Eyes Nations + Japan, India Ask Big Tech To Bake Backdoors Into Everything
by Lawrence D'Oliveiro 12 Oct '20

12 Oct '20

The abovementioned nations have issued a joint statement <https://www.theregister.com/2020/10/11/international_statementon_end_to_end…> where they “urge industry to address our serious concerns where encryption is applied in a way that wholly precludes any legal access to content”. One of the ways to do this is “Enable law enforcement access to content in a readable and usable format where an authorisation is lawfully issued, is necessary and proportionate, and is subject to strong safeguards and oversight”. To the extent that this is not calling for restrictions on strong encryption altogether, merely on its wide adoption by certain large companies, I can live with it. Just so long as we are not forced into using the products and services provided by these companies as an inescapable part of our daily lives.

The Unreasonable Effectiveness Of The Julia Programming Language
by Lawrence D'Oliveiro 10 Oct '20

10 Oct '20

A report from the recent JuliaCon <https://arstechnica.com/science/2020/10/the-unreasonable-effectiveness-of-t…>: Six years ago, I wrote in these pages about the enduring prominence of Fortran for scientific computing and compared it with several other languages. I ended that article with a prediction that, in 10 years, a new language called Julia stood a good chance of becoming the one that scientists would turn to when tackling large-scale numerical problems. My prediction was not very accurate, though. It actually only took Julia about half that time. He goes on to talk about the “two-language problem” and the “expression problem”, and how Julia solves these through its “multiple-dispatch” feature. A key point is that, even with all these advanced features, it manages to maintain program speed close to that of C++.

Oracle vs Google Goes To The US Supreme Court
by Lawrence D'Oliveiro 07 Oct '20

07 Oct '20

The US Supreme Court is due to hear Google’s appeal tomorrow <https://arstechnica.com/tech-policy/2020/10/google-asks-supreme-court-to-ov…> against the CAFC ruling that APIs are copyrightable and that Google infringed Oracle’s copyright on the Java APIs. A few companies (including GitHub) have filed “amicus curiae” briefs explaining why allowing the verdict against Google to stand will have unfortunate consequences for the entire software industry. The CAFC (Court of Appeals for the Federal Circuit) is a notoriously “intellectual-property-friendly” court, shall we say. They wouldn’t even have got the chance to rule on the original verdict by Judge Alsup, except that the suit initially included a patent claim (that was very quickly thrown out). Definite points to Oracle’s lawyers for doing this: like a chess strategy where you advance a seemingly unimportant pawn in the opening moves that is immediately sacrificed, but the long-term consequences for your opponent’s position only become apparent some time later in the game.

Developers Are Managing 100× More Code Than They Were 10 Years Ago
by Lawrence D'Oliveiro 05 Oct '20

05 Oct '20

This survey <https://arstechnica.com/gadgets/2020/10/sourcegraph-devs-are-managing-100x-…> reports on the explosion in typical source code bases that seems to have occurred over the past decade. I have a couple of concerns with this: * The obvious quantity-versus-quality issue. How much of this is due to things like node.js pulling in hundreds of dependencies for a comparatively small class library? Clearly, “managing” does not mean “writing” or even “maintaining”. * The use of “technology” as some kind of synonym for “information technology”. You mean it didn’t require “technology” to conduct insurance, retail, food and beverage businesses before? After all, pencil and paper are “technologies”, too. And if you think they are easy things to make, well ... try making them yourself. </rant>

What Operating Systems Keep Things Running In Space?
by Lawrence D'Oliveiro 05 Oct '20

Nice report <https://arstechnica.com/features/2020/10/the-space-operating-systems-bootin…> going into some details on the proprietary VxWorks (popular with NASA) and the open-source RTEMS (originating from the US military, now heavily used by ESA). Also mentions SpaceChain, which was developed in order to implement a BitCoin network in space. This is based on Sylix, which comes from the Chinese military, but is now open-source as well. And there is some use of Linux, but only in situations where hard-realtime constraints can be guaranteed by lower-level custom hardware. Summary: VxWorks and RTEMS are pretty much identical in basic features and maturity/reliability, but RTEMS does have an edge in configurability.

DigitalOcean’s “Hacktoberfest” Backfires
by Lawrence D'Oliveiro 03 Oct '20

03 Oct '20

Cloud company Digital Ocean has started its seventh annual “Hacktoberfest” <https://www.theregister.com/2020/10/01/digitalocean_hacktoberfest_pull_requ…>, promising free T-shirts to those who submit “quality” pull requests to online open-source repositories. Seems this year, the “quality” proviso is being roundly ignored. Many project maintainers are being deluged with trivial and pointless patches, many of whose submittors readily admit they are only doing it for the T-shirt. Choice quote: Imagine an arsonist declaring, "Only you can prevent forest fires," and you can get a sense of the frustration among open source maintainers. Actually, I’m surprised this hasn’t happened in previous years. But then again, maybe it has: "Hacktoberfest has never generated anything of value for open source ... It’s a marketing stunt which sends a deluge of low-effort contributions to maintainers, leaving them to clean up the spam." There’s also a link to a rather pungently-named Twitter account which is collecting examples of these useless patch submissions.

Developers Try Again To Upstream Motorola 68000 Series Support In LLVM
by Peter Reutemann 01 Oct '20

01 Oct '20

'Hobbyist developers are trying once again to get a Motorola 68000 back-end merged into the upstream LLVM compiler. Phoronix reports: The Motorola 68000 series processors have been around since the 80's thanks to the likes of the early Apple Macintosh computers. Fast forward to 2020, the Motorola 68000 is still a popular target for vintage computer enthusiasts and hobbyists. Community developers have worked on improving the Linux kernel support for M68k hardware like early Apple Powerbooks as recently as a few years ago and the compiler support is a continued target. GCC 11 due out next year was looking to drop the M68k target over its unmaintained status. Hobbyists though stepped up there so the M68k support will remain in GCC. Now developers are also looking at adding M68k support to the LLVM compiler. This isn't the first time that M68k support for LLVM has been brought up albeit never successfully landed to date. Building off the past failures to get the Motorola 68000 series support upstreamed, developers last week sent out new patches proposing this back-end -- this time they are showing more clarity about the developers involved and being committed to supporting the code, the sustainability of the code, and responding quickly to code review comments. This patch series is the latest attempt at upstreaming Motorola 68000 series support in LLVM. Besides all the back-end specific code there is also some common LLVM code changes that fall under greater scrutiny.

Xen Project Officially Ports Its Hypervisor To Raspberry Pi 4
by Peter Reutemann 30 Sep '20

30 Sep '20

'The Xen Project has ported its hypervisor to the 64-bit Raspberry Pi 4. The Register reports: The idea to do an official port bubbled up from the Xen community and then reached the desk of George Dunlap, chairman of the Xen Project's Advisory Board. Dunlap mentioned the idea to an acquaintance who works at the Raspberry Pi Foundation, and was told that around 40 percent of Pis are sold to business users rather than hobbyists. With more than 30 million Arm-based Pis sold as of December 2019, and sales running at a brisk 600,000-plus a month in April 2020, according to Pi guy Eben Upton, Dunlap saw an opportunity to continue Xen's drive towards embedded and industrial applications. Stefano Stabellini, who by day works at FPGA outfit Xilinx, and past Apache Foundation director Roman Shaposhnik took on the task of the port. The pair clocked that the RPi 4's system-on-chip used a regular GIC-400 interrupt controller, which Xen supports out of the box, and thought this was a sign this would, overall, be an easy enough job. That, the duo admitted, was dangerous optimism. Forget the IRQs, there was a whole world of physical and virtual memory addresses to navigate. The pair were "utterly oblivious that we were about to embark on an adventure deep in the belly of the Xen memory allocator and Linux address translation layers," we're told. [The article goes on to explain the hurdles that were ahead of them.] "Once Linux 5.9 is out, we will have Xen working on RPi4 out of the box," the pair said. [...] Stefano Stabellini told The Register that an official Xen-on-RPi port will make a difference in the Internet-of-Things community, because other Arm development boards are more costly than the Pi, and programmers will gravitate towards a cheaper alternative for prototyping. He also outlined scenarios, such as a single edge device running both a real-time operating system alongside another OS, each dedicated to different tasks but inhabiting the same hardware and enjoying the splendid isolation of a virtual machine rather than sharing an OS as containers. George Dunlap also thinks that an official Xen-on-RPi port could also be of use to home lab builders, or perhaps just give developers a more suitable environment for their side projects than a virtual machine or container on their main machines. Stay tuned to Project EVE's Github page for more details about how to build your own Xen-for-RPi. Hacks to get it up and running should also appear on the Xen project blog.' -- source: https://hardware.slashdot.org/story/20/09/29/2025213 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/

Cloudflare's Privacy Crusade Continues With a Challenge To Google Analytics
by Peter Reutemann 30 Sep '20

30 Sep '20

'Fortune: Cloudflare is launching a privacy-friendly rival to Google Analytics. Google Analytics is a free toolkit that's used by website administrators across the globe to help them track the behavior of the people visiting those sites -- how they find them, what they do there, the devices they're using, and so on. However, the service -- the most popular of its kind -- also helps Google track websites' visitors, so it can better profile them for advertising purposes. This privacy-invasive aspect makes many people squeamish. And that's where Cloudflare would now like to step in. Around its birthday every year, the decade-old company -- which went public last year -- announces a move intended to "give back" to the wider Internet community. These moves are often related to privacy. On Tuesday, it unveiled Cloudflare Web Analytics, a free-to-use toolkit that largely replicates what Google Analytics offers -- minus the invasive tracking, and thus the ability to assess the performance of targeted ads carried on websites. Cloudflare Web Analytics is immediately available to the company's paid customers, but any website owner will be able to use it from some point in the coming months. Cloudflare's scale is crucial here [...] because it takes substantial resources to run a free analytics platform, and Cloudflare already has a giant network that can support the load. Cloudflare Web Analytics isn't the company's only big announcement this week. "On Monday, Cloudflare launched a beta testing program for a cloud technology called Durable Objects," the report adds. "You can read the technical explanation here, but in essence this is a tool that allows developers of online services to make those services comply with the increasing number of data-localization and data-protection laws that limit where users' data is supposed to go." "With Durable Objects, Cloudflare says, it is possible to specify where particular data will reside on Cloudflare's network, so -- for example -- a German user's data does not have to leave Germany. Or, with an eye to other current news, a service such as TikTok could ensure that U.S. users' data never leaves the U.S., without having to create a separate version of its service for that country."

Google Removes 17 Android Apps Caught Engaging In WAP Billing Fraud
by Peter Reutemann 30 Sep '20

30 Sep '20

'Google has recently removed 17 Android applications from the official Play Store because they were infected with the Joker (aka Bread) malware. ZDNet reports: "This spyware is designed to steal SMS messages, contact lists, and device information, along with silently signing up the victim for premium wireless application protocol (WAP) services," Zscaler security researcher Viral Gandhi said this week. The 17 malicious apps were uploaded on the Play Store this month and didn't get a chance to gain a following, having been downloaded more than 120,000 times before being detected. Following its internal procedures, Google removed the apps from the Play Store, used the Play Protect service to disable the apps on infected devices, but users still need to manually intervene and remove the apps from their devices. But this recent takedown also marks the third such action from Google's security team against a batch of Joker-infected apps over the past few months. [...] The way these infected apps usually manage to sneak their way past Google's defenses and reach the Play Store is through a technique called "droppers," where the victim's device is infected in a multi-stage process. Malware authors begin by cloning the functionality of a legitimate app and uploading it on the Play Store. This app is fully functional, requests access to dangerous permissions, but also doesn't perform any malicious actions when it's first run. Because the malicious actions are usually delayed by hours or days, Google's security scans don't pick up the malicious code, and Google usually allows the app to be listed on the Play Store. But once on a user's device, the app eventually downloads and "drops" (hence the name droppers, or loaders) other components or apps on the device that contain the Joker malware or other malware strains.

Ubuntu - Online upgrade to 20.04.1 now available
by Ian Stewart 29 Sep '20

29 Sep '20

Hi All, I mentioned last night at the WLUG meeting that there had been a delay in releasing the Ubuntu 18.04 to 20.04.1 online upgrade. As of today, the Focal Fossa (20.04.1 LTS) Point-Release Status Tracking webpage<https://discourse.ubuntu.com/t/focal-fossa-20-04-1-lts-point-release-status…> is still showing Status 20.04.1 Released! Upgrades from 18.04 to 20.04.1 still disabled ...but with... Upgrade blockers None Previously two bugs, 1891680<https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1891680> and 1876506<https://bugs.launchpad.net/ubuntu/focal/+source/os-prober/+bug/1876506> had been shown as the "upgrade blockers". These bugs were fixed in the last few weeks. Despite the above message, today on my Ubuntu Mate 18.04 laptop, I ran the GUI application "Software Updater". When it completed it stated: The software on this computer is up to date. However, Ubuntu 20.04.1 LTS is now available (you have 18.04). I clicked on "Upgrade". There were 384 new packages to install and 1547 packages to upgrade requiring about 1.4GB of downloading. On my rather slow 1.4GHz CPU, but with reasonably fast internet and a SSD it took 50 minutes to do the upgrade. cheers, Ian. PS: The upgrade kept my python Version 2 at V2.7.18 and upgraded Python3 to 3.8.2. If I had done a fresh install from DVD/USB of Ubuntu 20.04.1 it would not have installed Python 2.

Eric S. Raymond: Is Microsoft Switching To a Linux Kernel That Emulates Windows?
by Peter Reutemann 28 Sep '20

28 Sep '20

'Most of Microsoft's money now comes from its cloud service Azure, points out open-source advocate Eric S. Raymond. Now he posits a future where Windows development will "inevitably" become a drag on Microsoft's business: So, you're a Microsoft corporate strategist. What's the profit-maximizing path forward given all these factors? It's this: Microsoft Windows becomes a Proton-like emulation layer over a Linux kernel, with the layer getting thinner over time as more of the support lands in the mainline kernel sources. The economic motive is that Microsoft sheds an ever-larger fraction of its development costs as less and less has to be done in-house. If you think this is fantasy, think again. The best evidence that it's already the plan is that Microsoft has already ported Edge to run under Linux. There is only one way that makes any sense, and that is as a trial run for freeing the rest of the Windows utility suite from depending on any emulation layer. So, the end state this all points at is: New Windows is mostly a Linux kernel, there's an old-Windows emulation over it, but Edge and the rest of the Windows user-land utilities don't use the emulation. The emulation layer is there for games and other legacy third-party software. Economic pressure will be on Microsoft to deprecate the emulation layer... Every increment of Windows/Linux convergence helps with that — reduces administration and the expected volume of support traffic. Eventually, Microsoft announces upcoming end-of-life on the Windows emulation. The OS itself , and its userland tools, has for some time already been Linux underneath a carefully preserved old-Windows UI. Third-party software providers stop shipping Windows binaries in favor of ELF binaries with a pure Linux API... ...and Linux finally wins the desktop wars, not by displacing Windows but by co-opting it. Perhaps this is always how it had to be.' -- source: https://linux.slashdot.org/story/20/09/27/193250 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 is Not Unix Emacs Developers (Including Richard Stallman) Discuss How to Build a More 'Modern' Emacs
by Peter Reutemann 27 Sep '20

27 Sep '20

'LWN.net re-visits the emacs-devel mailing list, where the Emacs 28 development cycle has revived discussions about how to make the text editor more "modern" and attractive to new users: A default dark theme may not be in the future, leading one to think that there may yet be hope for the world in general. But there does seem to be general agreement that Emacs could benefit from a better, more centralized approach to color themes, rather than having color names hard-coded throughout various Elisp packages. From that, a proper theme engine could be supported, making dark themes and such easily available to those who want them... Another area where Emacs is insufficiently "modern", it seems, has to do with keyboard and mouse bindings. On the keyboard side, users have come to expect certain actions from certain keystrokes; ^X to cut a selection, ^V to paste it, etc. These bindings are easily had by turning on the Cua mode, but new users tend not to know about this mode or how to enable it. Many participants in the discussion said that this mode should be on by default. That, of course, would break the finger memory of large numbers of existing Emacs users, who would be unlikely to appreciate the disruption. Or, as Richard Stallman put it: It is not an option to change these basic key bindings to imitate other, newer editors. It would create a different editor that we Emacs users would never switch to. It is unfortunate that the people who implemented the newer editors chose incompatibility with Emacs.... The situation with mouse behavior is similar; as several participants in the discussion pointed out, users of graphical interfaces have come to expect that a right-button click will produce a menu of available actions. In Emacs, instead, that button marks a region ("selection"), with a second click in the same spot yanking ("cutting") the selected text. Many experienced Emacs users have come to like this behavior, but it is surprising to newcomers. The right mouse button with the control key held down does produce a menu defined by the current major mode, but that is evidently not what is being requested here; that menu, some say, should present global actions rather mode-specific ones. Stallman suggested offering a "reshuffled mode" that would bring the context menu to an unadorned right-button click, and which would add some of the expected basic editing commands there as well. This would be relatively easy to do, he said, since mouse bindings are separate from everything else. Besides, as he noted, the current mouse behavior was derived from "what was the standard in X Windows around 1990"; while one wouldn't want to act in haste, it might just be about time for an update. Other proposed changes involved "discoverability," including the default enabling of various modes, although to incorporate them into GNU Emacs "would often require the author to sign copyrights over to the Free Software Foundation, which is not something all authors are willing to do..."' -- source: https://news.slashdot.org/story/20/09/25/2213230 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/

Bored Developer Creates 'DOS Subsystem For Linux'
by Peter Reutemann 27 Sep '20

27 Sep '20

'iTnews: A software engineer in Melbourne is whiling away the city's lockdown by creating a tool that DOS users so far have lacked: an integrated Linux environment similar to what Windows 10 users enjoy... "I first started out just seeing if I could get Linux booting from the DOS command line, and that turned out to be straightforward enough so I thought it'd be fun to see if I could continue executing DOS once Linux was running," Charlie Somerville said. "I'm mostly surprised by how smoothly the whole thing works given how *dodgy* it all is haha," he added. DOS Subsystem for Linux runs a real copy of MS-DOS under the QEMU virtual machine, and starts up from that, Somerville said... "Helpfully Linux seems to leave the first megabyte of memory (where DOS lives) intact during its own boot process, so it's just a matter of jumping back to the right place to continue DOS execution," he added. Somerville had it pointed out to him that this approach of running DOS under vm8086 is actually how early Windows worked. "Kinda cool to rediscover the technique so many years later," Somerville said.' -- source: https://linux.slashdot.org/story/20/09/26/048223 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/

Bug Allowed Hijacking Other Firefox Mobile Browsers on the Same Wi-Fi Network
by Peter Reutemann 27 Sep '20

27 Sep '20

'"Mozilla has fixed a bug that can be abused to hijack all the Firefox for Android browsers on the same Wi-Fi network and force users to access malicious sites, such as phishing pages," reports ZDNet: The bug was discovered by Chris Moberly, an Australian security researcher working for GitLab. The actual vulnerability resides in the Firefox SSDP component. SSDP stands for Simple Service Discovery Protocol and is the mechanism through which Firefox finds other devices on the same network in order to share or receive content (i.e., such as sharing video streams with a Roku device). When devices are found, the Firefox SSDP component gets the location of an XML file where that device's configuration is stored. However, Moberly discovered that in older versions of Firefox, you could hide Android "intent" commands in this XML and have the Firefox browser execute the "intent," which could be a regular command like telling Firefox to access a link... The bug was fixed in Firefox 79; however, many users may not be running the latest release. Firefox for desktop versions were not impacted.

Facebook “Took A Page From Big Tobacco’s Playbook”
by Lawrence D'Oliveiro 26 Sep '20

26 Sep '20

Some former Facebook employees are testifying to the US Congress <https://arstechnica.com/tech-policy/2020/09/former-facebook-manager-we-took…> as part of a hearing into the role social media platforms play in spreading extremist and radical content. Tim Kendall, former director of monetization, says: “We took a page form Big Tobacco’s playbook, working to make our offering addictive at the outset.” After making some more direct comparisons with how tobacco companies made their product more addictive, he talked about “engagement”, which was the measure Facebook tried to maximize above all else: “We initially used engagement as sort of a proxy for user benefit,” Kendall explained. “But we also started to realize that engagement could also mean [users] were sufficiently sucked in that they couldn’t work in their own best long-term interest to get off the platform... We started to see real-life consequences, but they weren’t given much weight. Engagement always won, it always trumped.” If a company becomes large and powerful, and cannot be trusted to exercise that power responsibly, then it must be taken from them.

Researchers Found the Manual For the World's Oldest Surviving Computer
by Peter Reutemann 24 Sep '20

24 Sep '20

'Researchers will be able to gain a deeper understanding of what's considered the world's oldest surviving (digital) computer after its long-lost user manual was unearthed. Engadget reports: The Z4, which was built in 1945, runs on tape, takes up most of a room and needs several people to operate it. The machine now takes residence at the Deutsches Museum in Munich, but it hasn't been used in quite some time. An archivist at ETH Zurich, Evelyn Boesch, discovered the manual among her father's documents in March, according to retired lecturer Herbert Bruderer. Rene Boesch worked with the Swiss Aeronautical Engineering Association, which was based at the university's Institute for Aircraft Statics and Aircraft Construction. The Z4 was housed there in the early 1950s. Among Boesch's documents were notes on math problems the Z4 solved that were linked to the development of the P-16 jet fighter. "These included calculations on the trajectory of rockets, on aircraft wings, on flutter vibrations [and] on nosedive," Bruderer wrote in a Association of Computing Machinery blog post.' -- source: https://hardware.slashdot.org/story/20/09/23/2058222 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/

Firefox usage is down 85% despite Mozilla's top exec pay going up 400%
by Peter Reutemann 24 Sep '20

24 Sep '20

'Mozilla recently announced that they would be dismissing 250 people. That's a quarter of their workforce so there are some deep cuts to their work too. The victims include: the MDN docs (those are the web standards docs everyone likes better than w3schools), the Rust compiler and even some cuts to Firefox development. Like most people I want to see Mozilla do well but those three projects comprise pretty much what I think of as the whole point of Mozilla, so this news is a a big let down. The stated reason for the cuts is falling income. Mozilla largely relies on "royalties" for funding. In return for payment, Mozilla allows big technology companies to choose the default search engine in Firefox - the technology companies are ultimately paying to increase the number of searches Firefox users make with them. Mozilla haven't been particularly transparent about why these royalties are being reduced, except to blame the coronavirus. I'm sure the coronavirus is not a great help but I suspect the bigger problem is that Firefox's market share is now a tiny fraction of its previous size and so the royalties will be smaller too - fewer users, so fewer searches and therefore less money for Mozilla. The real problem is not the royalty cuts, though. Mozilla has already received more than enough money to set themselves up for financial independence. Mozilla received up to half a billion dollars a year (each year!) for many years. The real problem is that Mozilla didn't use that money to achieve financial independence and instead just spent it each year, doing the organisational equivalent of living hand-to-mouth. Despite their slightly contrived legal structure as a non-profit that owns a for-profit, Mozilla are an NGO just like any other. In this article I want to apply the traditional measures that are applied to other NGOs to Mozilla in order to show what's wrong.' -- source: http://calpaterson.com/mozilla.html 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/

Automated Unit Testing: Quis Custodiet Ipsos Custodes?
by Lawrence D'Oliveiro 22 Sep '20

22 Sep '20

A company called Diffblue has a product that uses AI techniques to automatically generate unit tests for your code <https://www.theregister.com/2020/09/21/diffblue_let_ai_code_unit_tests/>. Only problem is, it doesn’t actually know what the intent of your code is, so it assumes it is correct to begin with, and generates tests on that basis. So who tests the test code? It falls back to a human to ensure the tests make sense. But doesn’t that defeat the point of having them done automatically? Unless you only use the system to catch regressions--things that were previously working, but get broken by newer changes to the code. Even then, it seems to me there is a likelihood of false positives, caused by refactoring of functionality between different modules; too many of these, and the humans are going to start ignoring the test results.

GNOME Gets New Versioning Scheme
by Peter Reutemann 22 Sep '20

22 Sep '20

'The GNOME 3 desktop environment was officially released in 2011, and in 2020 we are still on version 3.x. Yeah, despite many massive changes over the last (almost) decade, we have been stuck with point releases for GNOME 3. For instance, just last week, GNOME 3.38 was released. Historically, the stable releases all ended in even numbers, with pre-release versions ending in odd. For fans of the DE, such as yours truly, we have simply learned to live with this odd versioning scheme. Well, folks, with the next version of GNOME, the developers have finally decided to move on from version 3.x. You are probably thinking the new version will be 4.0, but you'd be very wrong. Actually, following GNOME3.38 will be GNOME 40. "After nearly 10 years of 3.x releases, the minor version number is getting unwieldy. It is also exceedingly clear that we're not going to bump the major version because of technological changes in the core platform, like we did for GNOME 2 and 3, and then piling on a major UX change on top of that. Radical technological and design changes are too disruptive for maintainers, users, and developers; we have become pretty good at iterating design and technologies, to the point that the current GNOME platform, UI, and UX are fairly different from what was released with GNOME 3.0, while still following the same design tenets," says Emmanuele Bassi, The GNOME Foundation.' -- source: https://linux.slashdot.org/story/20/09/21/1652221 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/

'Two professors at the University of Massachusetts have co-authored a new essay explaining how open source licensing "could keep Big Pharma from making huge profits off taxpayer-funded research" in the international, multi-billion-dollar race for a Covid-19 vaccine: The invention of the "General Public License," sometimes referred to as a viral or reciprocal license, meant that should an improvement be made, the new software version automatically inherits the same license as its parent. We believe that in a time of a global pandemic, a safe and effective COVID-19 vaccine should be licensed with General Public License-like properties... Fortunately, some pharmaceutical companies, national governments, nonprofits like the Bill & Melinda Gates Foundation and international organizations like the Coalition for Epidemic Preparedness Initiatives — which supports vaccine development — are putting policies in place that embrace openness and sharing rather than intellectual property protection. Coalition for Epidemic Preparedness Initiatives officials have stated that all of their funding agreements require that "appropriate vaccines are first available to populations when and where they are needed to end an outbreak or curtail an epidemic, regardless of ability to pay." That's an important start. However, when there is a safe, effective COVID-19 vaccine, the U.S. and other national governments need to create contractual agreements with firms that provide fair and reasonable funding to cover their costs or even some reasonable profit margin while still mandating the open sharing of the processes for vaccine production, quality assurance and rapid global distribution.' -- source: https://science.slashdot.org/story/20/09/20/2359229 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/

'Raymond Hill, known online as gorhill, has set the status of the uMatrix GitHub repository to archived; this means that it is read-only at the time and that no updates will become available. The uMatrix extension is available for several browsers including Firefox, Google Chrome, and most Firefox and Chromium-based browsers. It is a privacy and security extensions for advanced users that provides firewall-like capabilities when it is installed... Hill suggests that developers could fork the extension to continue development under a new name. There is also the chance that Hill might resume development in the future but there is no guarantee that this is going to happen. For now, uMatrix is no longer in active development.

DuckDuckGo Is Growing Fast
by Peter Reutemann 18 Sep '20

'DuckDuckGo, the privacy-focused search engine, announced that August 2020 ended in over 2 billion total searches via its search platform. While Google remains the most popular search engine, DuckDuckGo has gained a great deal of traction in recent months as more and more users have begun to value their privacy on the internet. DuckDuckGo saw over 2 billion searches and 4 million app/extension installations, and the company also said that they have over 65 million active users. DuckDuckGo could shatter its old traffic record if the same growth trend continues. Even though DuckDuckGo is growing rapidly, it still controls less than 2 percent of all search volume in the United States. However, DuckDuckGo's growth trend has continued throughout the year, mainly due to Google and other companies' privacy scandal.' -- source: https://yro.slashdot.org/story/20/09/17/2036241 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/
