List Of IPTV Resources
by Lawrence D'Oliveiro 22 Sep '24

22 Sep '24

This user <https://github.com/iptv-org> just popped up in my GitHub feed. One repo <https://github.com/iptv-org/iptv> claims to be a list of links to over 8000 streaming TV channels from nations all over the world, while the other is a list of tools*, providers and other resources. Do be aware it’s a bit of a mixed bag: yes, there are legitimate channels (no encryption so far that I have noticed), but also some dubious-looking links. *Oddly, FFmpeg and youtube-dl aren’t in the list.

Enabling Case-Insensitive Filenames On Linux
by Lawrence D'Oliveiro 06 Feb '24

06 Feb '24

The ext4 filesystem has had the “casefold” option for a while now <https://lwn.net/Articles/784041/>. This allows you to specify, when you initialize a new filesystem, that you want file/directory names to be treated as case-insensitive. At the same time, you have to specify that the filenames are to be interpreted as UTF-8 encoding; normally the kernel doesn’t care, it only singles out ASCII slash and NUL bytes for special interpretation, and simply passes through any other byte values in the names. I was able to create such a filesystem, but I wasn’t able to mount it in my last-upgraded-just-a-few-days-ago Debian Unstable setup. When I try, it fails, and in the dmesg log I see Filesystem with casefold feature cannot be mounted without CONFIG_UNICODE Turns out the Debian 5.10 kernel has not been built with this CONFIG_UNICODE option enabled. However, this situation looks set to change shortly, according to <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=985689>.

Weta Digital’s Technology Division Sold To US Firm
by Lawrence D'Oliveiro 30 Nov '23

30 Nov '23

Let me see if I understand this article <https://www.nzherald.co.nz/business/sir-peter-jackson-to-sell-weta-digital-…> correctly: the part of Weta Digital that used to develop the in-house 3D graphics/effects tools that they use in all those movies is being sold to US-based Unity Software. The part that is left will be called “WetaFX”, and will become a customer of Unity for the use of those tools, no longer doing its own development in-house. By the way, I’ve been looking at the Unity site <https://unity.com/>, and it looks like all their products are rentware (subscription-based).

Outlawing Dark Patterns
by Lawrence D'Oliveiro 05 Nov '22

05 Nov '22

“Dark patterns” is a term coined to describe user interfaces designed to manipulate people into giving up time, money or personal data that they didn’t intend to. A common example is the obstacle course you often have to go through to cancel a subscription to something online. Another example is the use of countdown timers to rush buyers into hasty decisions. They may not be out-and-out deceptive, but they do come close. Now, the US states of California and Washington are looking to pass laws to restrict this practice. <https://arstechnica.com/tech-policy/2021/01/lawmakers-take-aim-at-insidious…>

Apple’s Windows 10
by Lawrence D'Oliveiro 19 Jul '22

19 Jul '22

Fred Brooks predicted long ago that complex pieces of software would eventually reach the point of irreducible entropy, where any attempt to fix a bug would simply introduce a new one. Microsoft’s Windows 10 seems to be about there, and it’s now clear that Apple’s macOS 10.15 “Catalina” has also joined that elite group <https://www.theregister.co.uk/2020/05/27/apple_catalina_update/>: The first spin of Catalina, officially released in October 2019, was a mess. ... The biggest issue was that all kinds of apps simply stopped working. ... Peripherals like mice, keyboards and printers stopped working. Email went missing; iCloud backups failed; users were constantly harassed by login requests; updates didn’t update ... ... So came for the first update to its new system one week after the main launch which fixed some, but not all, of the issues. ... Version two came in December 2019 and fixed some of those issues, but not all. ... More bug fixes came with version three in January 2020, but the OS seemed to have finally stabilized; something that was then spectacularly undone with version .4. ... Then we had the “supplemental update” to version 10.15.4, which fixed some, but not all, of the problems – most significantly the problem with Finder and transferring large files. And, amazingly, appeared to undo the good work that had been done with website security and broke SSH for some users. But now, with version point-five this week, that problem appears to have been sorted and, of course, your battery might last longer too.

Microsoft finds Linux desktop flaw that gives root to untrusted users
by Peter Reutemann 14 Jun '22

14 Jun '22

'Vulnerabilities recently discovered by Microsoft make it easy for people with a toehold on many Linux desktop systems to quickly gain root system rights— the latest elevation of privileges flaw to come to light in the open source OS. As operating systems have been hardened to withstand compromises in recent years, elevation of privilege (EoP) vulnerabilities have become a crucial ingredient for most successful hacks. They can be exploited in concert with other vulnerabilities that on their own are often considered less severe, with the latter giving what’s called local access and the former escalating the root access. From there, adversaries with physical access or limited system rights can deploy backdoors or execute code of their choice. Nimbuspwn, as Microsoft has named the EoP threat, is two vulnerabilities that reside in the networkd-dispatcher, a component in many Linux distributions that dispatch network status changes and can run various scripts to respond to a new status. When a machine boots, networkd-dispatcher runs as root. The flaws, tracked as CVE-2022-29799 and CVE-2022-29800, combine threats including directory traversal, symlink race, and time-of-check time-of-use (TOCTOU) race condition.' -- source: https://arstechnica.com/information-technology/2022/04/microsoft-finds-linu… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

FairEmail Developer Calls It Quits After Google Falsely Flags App As Spyware
by Peter Reutemann 01 Jun '22

01 Jun '22

'"The developer of the open source email client FairEmail pulled all of his applications from Google Play and announced that he would stop development," reports gHacks. The announcement comes shortly after the developer received an email from Google stating that they believed the app was spyware. From the report: FairEmail was a popular email client for Google's Android operating system that was free to use. It was privacy-friendly, had no limitations in regards to email accounts that users could set up in the app, supported unified inbox, conversation threading, two-way synchronizing, support for OpenPGP, and a lot more. Marcel Bokhorst, the developer of the application, announced major changes to the project yesterday on XDA Developers. Earlier that week, Bokhorst received a policy violation email from Google stating that Google believed that the FairEmail application was spyware. The full statement has not been published, but Bokhorst believes that Google might have misinterpreted the use of favicons in the app. He resubmitted a new version of the application that had the use of favicons removed. The appeal he received as a response "resulted in a standard answer". While the content of the answer is unclear, it appears to have been a generic answer that Google Play Store developers have been frustrated with for a long time. Bokhorst decided to pull the application and all of his other applications from the Google Play Store. The apps won't be maintained and supported anymore according to the info. Other factors played a role in Bokhorst's decision, including the discrepancy between answering thousands of support questions per month and the application's revenue, and the inability to do something against unfair reviews in the Google Play Store. He considered keeping the applications on GitHub, but this would result in an 98% loss of audience. Google also recently forced Total Commander's developer to remove the ability to install APKs from the File Manager. If you're looking for an alternative email client, gHacks recommends the open-source app K-9 Mail.' -- source: https://tech.slashdot.org/story/22/05/19/2033249 Oh no, I just switched from K-9 to FairEmail a couple of months ago, as my K-9 was getting extremely slow with syncing mails...

Python Is Getting Faster: Major Performance Tweaks On Horizon
by Lawrence D'Oliveiro 01 Jun '22

01 Jun '22

This report <https://www.theregister.com/2022/05/16/python_is_getting_faster/> on what is coming in CPython 3.11 and subsequent versions talks a lot about speed improvements. Several people have looked at removing the “GIL” (“Global Interpreter Lock”), which is the single biggest obstacle to improving multithreading performance. But some kind of lock is essential to maintain reference counting of dynamically-allocated objects. Get rid of these reference counts and you move to a Java-style pure-garbage-collected model, where you can end up consuming endless amounts of RAM unless you impose explicit limits on application size. But there is this new project called “nogil” (linked in the article). Their design overview document (hosted on Google Docs) talks about, not getting rid of reference counting, but implementing a more decentralized version of it, to minimize concurrency bottlenecks. This sounds quite hopeful.

Vodafone Plans Carrier-Level User Tracking For Targeted Ads
by Peter Reutemann 01 Jun '22

01 Jun '22

'Vodafone is piloting a new advertising ID system called TrustPid, which will work as a persistent user tracker at the mobile Internet Service Provider (ISP) level. Vodafone explains that TrustPiD will be generated through randomness, and its subscribers will have the option to manage their consent over accepting the tracking via the company's Privacy Portal. BleepingComputer reports: The new system is in test phase in Germany and is intended to be impossible to bypass from within the web browser settings or through cookie blocking or IP address masking. The mobile carrier plans to assign a fixed ID to each customer and associate all user activity with it. The ID will be based on a number of parameters, so that the system will be able to maintain persistence. Then, the mobile ISP creates a personal profile based on that ID and helps advertisers serve targeted ads to each customer without disclosing any identification details. According to Vodafone, the problem that arises for its internet subscribers is that the "free" parts of the internet are threatened by stricter cookie blocking and privacy-boosting schemes. These new models threaten the targeted advertising industry, and according to Vodafone, the danger of this is losing content and platforms currently supported by ads. "Consumers appreciate the idea of a 'free' Internet, but this comes with a trade-off: publishers need a sustainable revenue model, meaning that it becomes essential to add subscription paywalls or rely on advertising to maintain free access to high-quality content," reads the explanation on the TrustPiD website, managed by Vodafone Sales and Services Limited.' -- source: https://yro.slashdot.org/story/22/05/31/2043256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Lotus 1-2-3 Ported To Linux
by Peter Reutemann 31 May '22

31 May '22

'Lotus-1-2-3, an ancient spreadsheet program from Lotus Software (and later IBM), has been ported to a new operating system. drewsup writes: As reported by The Register, a Lotus 1-2-3 enthusiast called Tavis Ormandy (who is also a bug-hunter for Google Project Zero), managed to successfully port the program onto Linux, which seems to be quite the feat of reverse engineering. It's important to stress that this isn't an emulated program, but rather the original 1990 Lotus 1-2 -- for x86 Unix running natively on modern x86 Linux.' -- source: https://linux.slashdot.org/story/22/05/30/1633208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
