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.

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.

Linux On Mars: NASA’s Ingenuity Helicopter Flies
by Lawrence D'Oliveiro 10 May '22

10 May '22

The first powered aircraft on Mars <https://www.theregister.com/2021/04/19/perseverance_computing_feature/> has proved its concept, taken flight for a few seconds, and made a controlled landing again. The control system is running Linux on a Qualcomm Snapdragon 801 chip, not because NASA considered it the best tool for the job, but because it was the easiest solution available. The hardware “is tuned for use on Earth, not Mars”, so it is only planned to make brief flights of no more than 90 seconds at a time, always landing back at the same spot, and it is not expected to endure beyond the initial 30 days of the Perseverance mission.

More On The NZ Reserve Bank Breach
by Lawrence D'Oliveiro 15 Sep '21

Seems hackers broke into a secure file-sharing service called Accellion, based in California. The RBNZ was using that to exchange documents with the likes of banks and insurance companies. <https://www.stuff.co.nz/business/123911764/reserve-bank-reveals-more-detail…>

On-Prem Windows Server: Are Its Days Numbered?
by Lawrence D'Oliveiro 31 Aug '21

31 Aug '21

Microsoft has released yet another typically confusing update on the future of its family of Windows Server products <https://www.theregister.com/2021/07/28/windows_server_2022_sac/>. What’s clear from the details is that development is primarily going into the cloudy versions of Windows Server, with those who prefer to manage their own instances on their own hardware being increasingly left behind: At a high level, it seems that Microsoft is investing in Azure and [Azure Kubernetes Service], and that on-premises Windows Server users are in some respects being left behind. It is notable, for example, that Active Directory's functional level has not changed since Windows Server 2016, and this remains the case in Server 2022. ... SMB over QUIC, which promises secure access to Windows file shares from anywhere, is another key feature which will be available only in Windows Server Azure Edition. The article notes that on-prem Windows Server being slowly moved to the back burner in this way “will not go down well with on-premises users, nor perhaps with rival clouds running Windows Server”. But then again, given that Microsoft’s own cloud offerings are predominantly Linux-based, I can’t see other cloud services doing any better with Windows.

New Android Malware Records Smartphones via VNC To Steal Passwords
by Peter Reutemann 30 Jul '21

30 Jul '21

'Security researchers have discovered a novel piece of Android malware that uses the VNC technology to record and broadcast a victim's smartphone activity, allowing threat actors to collect keyboard presses and app passwords. From a report: First spotted in March 2021 by Dutch security firm ThreatFabric, this new piece of malware, named Vultur, is a departure from other Android malware strains that usually rely on fake login screens floating on top of legitimate apps to collect a victim's credentials. Instead, Vultur opens a VNC server on the infected phone, and broadcasts screen captures to an attacker command and control server, where the Vultur operator extracts passwords for desired apps.' -- source: https://it.slashdot.org/story/21/07/29/1549220 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/

Warnings That Work: Combating Misinformation Without Deplatforming
by Lawrence D'Oliveiro 29 Jul '21

29 Jul '21

How do you flag misleading postings on Facebook and elsewhere about vaccination, Covid-19 and other issues? Currently these platforms add a little warning next to the posting. Evidence accumulated over many years has shown that such “contextual” warnings are mostly disregarded. What does work is “interstitial” warnings: something that interrupts the user, and forces them to make a choice to continue. This works for security issues on PCs and when browsing the Internet; it can work for postings on social media, too. This article <https://freedom-to-tinker.com/2021/07/26/warnings-that-work-combating-misin…> goes into more details.

New On Bitsavers This/Last Week
by Lawrence D'Oliveiro 28 Jul '21

28 Jul '21

Among the recent additions to the Bitsavers retrocomputing archive is a scan of the Mt Xinu 1993 calendar <http://bitsavers.trailing-edge.com/pdf/mtXinu/1993_MT_XINU_Calendar.pdf>. On the flip side of each month’s page is a collection of clippings from some interestingly mythical magazines and newspapers. For example, a purported article on “How to eat a meal near a keyboard -- Safely!” hints at an implement that is both “a mouse AND a scrub-brush!”. The cover of a magazine targeted at “computer professionals” touts a report on “Strategic partnerships: What CEOs should know about space aliens” as well as “DOS removers, do they do what they claim?” And then there’s the ad for improving the productivity of your staff with a department-wide installation of a product called ... UrethraNet ...

The Debian usrmerge Package
by Lawrence D'Oliveiro 27 Jul '21

27 Jul '21

There is a package in Debian (and no doubt also in its derivatives) called “usrmerge” <https://wiki.debian.org/UsrMerge>. The mere act of installing this will perform a “usr merge” on your system, which means that the contents of /bin are merged with /usr/bin, with the former becoming just a symlink to the latter, and similarly /sbin merged into /usr/sbin, and /lib merged into /usr/lib. Back in the last century, when hard drives were smaller, it was standard practice to put only the minimum core of executables and libraries into /bin, /sbin and /lib that would allow the system to boot into a state where a sysadmin could perform some basic maintenance tasks. All the less crucial, but nice to have stuff, would be in /usr, which would be mounted as a separate disk or partition. This way, I suppose, problems with the /usr volume could be fixed without the entire system becoming unbootable. These days, such a division is considered an anachronism. Debian hasn’t supported booting without /usr available for a long while now. I think some other distros, like Fedora, made the move a long time ago. And if you have problems with your OS partition, it’s easier to boot and fix things with something like SystemRescueCD anyway. Note that the usr merge, once performed, is not (easily) reversible. Also note that new Debian installs have been creating a merged usr system since version 10.
