Open Source Gets No Respect, Episode #310
by Lawrence D'Oliveiro 18 Dec '19

18 Dec '19

The developer of FUSE for macOS <https://www.theregister.co.uk/2019/12/16/fuse_macos_closed_source/> found that, while many companies were including his software in their commercial products, they were curiously reluctant to offer him any actual monetary support for his work. So he took the drastic step of making the latest version closed-source. While it continues to be available for non-commercial use at no charge, commercial vendors will need to license it for inclusion in their products. The result? He has actually got a bunch of licensing deals signed now.

Microsoft Begins Accepting Extensions For Its Edge Chromium Browser
by Peter Reutemann 17 Dec '19

17 Dec '19

'Microsoft's new Chromium-based Edge browser is now open to developers to submit extensions. The updated version of Edge is set to launch on January 15. From a report: Microsoft says that if a developer has already created an extension for Google Chrome, there shouldn't be any additional work to port it over to Edge Chromium. The browser will be the new default delivered to all 900 million Windows 10 users, so developers should have no reason not to port their extensions over.' -- source: https://slashdot.org/story/19/12/17/1621248 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/

Mozilla To Add Second DNS-over-HTTPS (DoH) Provider in Firefox
by Peter Reutemann 17 Dec '19

17 Dec '19

'Mozilla has announced that NextDNS would be joining Cloudflare as the second DNS-over-HTTPS (DoH) provider inside Firefox. From a report: The browser maker says NextDNS passed the conditions imposed by its Trusted Recursive Resolver (TRR) program, and can now be added as a second option for DoH inside Firefox. These conditions include (1) limiting the data NextDNS collects from the DoH server used by Firefox users; (2) being transparent about the data they collect; and (3) promising not to censor, filter, or block DNS traffic unless specifically requested by law enforcement. DNS-over-HTTPS, or DoH, is a new feature that was added to Firefox last year. When enabled, it encrypts DNS traffic coming in and out of the browser. DNS traffic is not only encrypted but also moved from port 53 (for DNS traffic) to port 443 (for HTTPS traffic), effectively hiding DNS queries and replies inside the browser's normal stream of HTTPS content. This encrypted DNS traffic reaches a so-called DoH resolver. Here, the DoH traffic is decrypted and the DoH resolver makes the DNS query on the user's behalf, receives the result, encrypts it, and sends it back to the user's browser -- also disguised inside encrypted HTTPS content.' -- source: https://tech.slashdot.org/story/19/12/17/1922254 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/

Npm Team Warns of New 'Binary Planting' Bug
by Peter Reutemann 16 Dec '19

16 Dec '19

' The team behind npm, the biggest package manager for JavaScript libraries, issued a security alert yesterday, advising all users to update to the latest version (6.13.4) to prevent "binary planting" attacks. From a report: Npm (Node.js Package Manager) devs say the npm command-line interface (CLI) client is impacted by a security bug -- a combination between a file traversal and an arbitrary file (over)write issue. The bug can be exploited by attackers to plant malicious binaries or overwrite files on a user's computer. The vulnerability can be exploited only during the installation of a boobytrapped npm package via the npm CLI. "However, as we have seen in the past, this is not an insurmountable barrier," said the npm team, referring to past incidents where attackers planed backdoored or boobytrapped packages on the official npm repository. Npm devs say they've been scanning the npm portal for packages that may contain exploit code designed to exploit this bug, but have not seen any suspicious cases. "That does not guarantee that it hasn't been used, but it does mean that it isn't currently being used in published packages on the [official npm] registry," npm devs said.' -- source: https://it.slashdot.org/story/19/12/16/1513245 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/

Google Halts Chrome 79 Rollout After It Breaks Some Android Apps
by Peter Reutemann 15 Dec '19

15 Dec '19

'Chrome 79 is creating an issue with WebView (the Android component that allows apps to display content from the web), reports 9to5Google: On Friday morning, Android developers reliant on WebView and local storage began encountering an issue where their apps lost data after users updated to version 79 of WebView. Those affected took to Chromium's bug tracker, and have described the incident as a "catastrophe" and "major issue." To end users, it's as if apps were entirely reset and just downloaded for the first time. This includes saved data disappearing or being logged out. Given the level of system opacity, most will blame developers for a problem that's out of their hands. By that afternoon, Google engineers responded and isolated the issue to "profile layout changes" where "local storage was missed off the list of files migrated." A member of the Chromium team apologized Saturday morning, with the Chrome/WebView rollout halted after 50% of devices already received the update. At the highest priority level (P0), Google is currently "working on a solution that minimizes the data loss, and that can be rolled out safely." The last guidance for a patch is 5-7 days.' -- source: https://tech.slashdot.org/story/19/12/15/181240 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/

'Link in Bio' is a Slow Knife
by Peter Reutemann 15 Dec '19

15 Dec '19

'Anil Dash: We don't even notice it anymore -- "link in bio." It's a pithy phrase, usually found on Instagram, which directs an audience to be aware that a pertinent web link can be found on that user's profile. Its presence is so subtle, and so pervasive, that we barely even noticed it was an attempt to kill the web. Links on the web are incredibly powerful. There are decades of theory behind the role of hyperlinks in hypertext -- did you know in most early versions, links were originally designed to be two-way? You'd be able to see every page on the web that links to this one. But even in the very simple form that we've ended up with on the World Wide Web for the last 30 years, links are incredibly powerful, opening up valuable connections between unexpected things. For a closed system, those kinds of open connections are deeply dangerous. If anyone on Instagram can just link to any old store on the web, how can Instagram -- meaning Facebook, Instagram's increasingly-overbearing owner -- tightly control commerce on its platform? If Instagram users could post links willy-nilly, they might even be able to connect directly to their users, getting their email addresses or finding other ways to communicate with them. Links represent a threat to closed systems. Here's the thing, though: people like links. So closed systems have to present a pressure release valve. Hashtags are a great way out. They use the semiotics of links (early versions of hashtags on social platforms were really barely more than automated links to a search for a particular term) but are also constrained by the platforms they live on. A hashtag is easier to gather into a database, to harvest, to monetize. It's much easier, sure, but it also doesn't have all the messiness of a real link. Instagram doesn't have to worry that clicking on its hashtags will accidentally lead people to Twitter, or vice versa.' -- source: https://tech.slashdot.org/story/19/12/12/1540216 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/

Building Your Own Open Source, Privacy-Protecting Voice Assistant With A Raspberry Pi
by Peter Reutemann 15 Dec '19

15 Dec '19

'PC Magazine's "tech nerd" Whitson Gordon writes that "Once you start using a smart speaker to set reminders, play the news, or turn the lights on, it's hard to go back." But if you want the convenience of voice control without the data-collecting tech giant behind the scenes, an open-source project called Mycroft is a great alternative. And you can run it right on a Raspberry Pi. Mycroft is a free, open-source voice assistant designed to run on Linux-based devices... Mycroft has been around for quite a few years, but it's recently gained a bit more notoriety thanks to privacy concerns surrounding data collection at Amazon and Google. Unlike those assistants, Mycroft only collects data if you opt in during setup. And for the users who do opt in, Mycroft promises never to sell your data to advertisers or third parties -- instead, it only uses it to help developers improve the product. Mycroft even uses the privacy-focused DuckDuckGo as its search engine instead of Google when you ask for information. Mycroft makes its own smart speaker called the Mark I, though it's currently sold out with a new Mark II (video here) on the way. However, since the project is open-source, you can install Mycroft on just about any Linux machine, including the Raspberry Pi (thanks to a pre-made build called Picroft). Using Mycroft on the Pi is free, but you can also subscribe to a $1.99-per-month plan to help support its development -- you'll even get a few goodies, like other voices that sound more lifelike than the default robotic voice.' -- source: https://hardware.slashdot.org/story/19/12/14/1954242 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/

Managing Spectre/Meltdown-Style Vulnerabilities At AWS
by Lawrence D'Oliveiro 15 Dec '19

15 Dec '19

Some insights <https://www.theregister.co.uk/2019/12/10/linux_kernel_aws/> into the different priorities often faced by different groups faced with the same problem. Linux kernel developer Greg Kroah-Hartman says to avoid most of these “MDS” (“Microarchitectural Data Sampling”) vulnerabilities, you must turn off Intel’s hyperthreading, full stop. Amazon, on the other hand, find that the resulting 30-40% performance loss is unacceptable for many of their customers. So they have come up with a tweaked scheduler algorithm for their Linux kernels that avoids running two different guests on the same physical core at the same time. With this and other careful management, they claim to be able to keep their customers safe from each other, with much less dramatic performance impact. But then you have the downside that the mainline kernel is not interested in accepting patches with such narrow applicability. Of course Amazon would like to come up with something they will accept, just to reduce their own maintenance burden.
