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.

Stopping Alert Volume Going To 100%
by Lawrence D'Oliveiro 20 Jan '21

20 Jan '21

For quite a while now, I’ve been annoyed by the system notification volume going to 100% on my Debian systems, regardless of my attempts to set it to a lower level. For example, when I open the KDE System Settings app, change something, then try to close the window, the sound that accompanies the save/discard/cancel alert is always startlingly loud. I think I have finally found a fix: in your /etc/pulse/daemon.conf, put in a line saying flat-volumes = no (You should find an existing comment “; flat-volumes = yes” that indicates the default.) You can make this new setting take effect in the current session immediately without having to logout or reboot, by executing the following as the currently-logged-in user: pulseaudio -k (This kills and restarts the PulseAudio daemon for your user session.) There are several discussions of the pros and cons of this issue online, going back some years. For example, here <https://bugzilla.redhat.com/show_bug.cgi?id=1265267>. Also a mention about the “flat-volumes” setting in the ever-reliable Arch Linux Wiki here <https://wiki.archlinux.org/index.php/PulseAudio>.

Random Firefox Tweaks
by Lawrence D'Oliveiro 12 Dec '20

12 Dec '20

Been looking at various settings changes you can make in the “about:config” page in Firefox. Here are a couple I have found useful: * keyword.enabled -- set to false to stop Firefox trying to do a search on the contents of the address box if it doesn’t match a URL. This is why I have a search box separate from the address box. * browser.fixup.alternate.enabled -- set to false to stop it helpfully tacking on “www.” and “.com” if the original URL you type doesn’t work. I have occasionally been confused by it complaining about not finding a URL, but showing a different one from the one I typed. By the way, when you first try to view this page, Firefox shows you a warning to ensure you understand the consequences of messing about with settings at this level. It remembers it has shown you this warning by adding the following line to the prefs.js file in your profile: user_pref("browser.aboutConfig.showWarning", false); Firefox seems to overwrite this file when it quits, and reloads it when it is launched again.

How Qualcomm Shook Down The Cell Phone Industry For Almost 20 Years
by Lawrence D'Oliveiro 15 Aug '20

15 Aug '20

A pretty sobering read <https://arstechnica.com/tech-policy/2019/05/how-qualcomm-shook-down-the-cel…>: Qualcomm's first weapon against competitors: patent licensing terms requiring customers to pay a royalty on every phone sold—not just phones that contained Qualcomm's wireless chips. Sound familiar? Judge Koh draws a direct parallel to licensing behavior that got Microsoft in legal trouble in the 1990s. Microsoft would offer PC makers a discount if they agreed to pay Microsoft a licensing fee for every PC sold—whether or not the PC shipped with a copy of MS-DOS. This effectively meant that a PC maker had to pay twice if it shipped a PC running a non-Microsoft operating system. There’s a lot more--the article reads like a catalogue of gangster-like tactics. All of which is perfectly all right under the US interpretation of “Free Enterprise”, of course ... Also, reading the details of how Qualcomm managed to sabotage Intel’s efforts to develop 5G chips, it seems to me that Qualcomm is directly responsible for the situation today where US companies are lagging behind Chinese ones like Huawei in 5G capability.

Edge TV Now Online-Only
by Lawrence D'Oliveiro 22 Apr '20

22 Apr '20

If there is anybody else besides me who wondered what happened to Edge TV, as of the beginning of this month it is no longer on Freeview, it can now only be viewed as an online stream <https://www.stuff.co.nz/entertainment/tv-radio/113928839/the-edge-tv-remove…>. In the last few days of June, there was a promo announcing that it was going HD, but I don’t recall it mentioning that it was leaving the broadcast airwaves. Quote: MediaWorks chief executive Michael Anderson says the move is in line with audience trends, which show people primarily consume music videos online. While that may be mostly true, personally I would go look for videos on YouTube after seeing them first on Edge TV.

Discord Switching From Go To Rust
by Lawrence D'Oliveiro 22 Apr '20

22 Apr '20

Came across this blog post <https://blog.discordapp.com/why-discord-is-switching-from-go-to-rust-a190bb…> explaining why Discord, which has been using Google’s Go language to implement its services, has now decided to rewrite them in Mozilla’s Rust. The problem was garbage collection. Go has a similar memory-allocation model to Java or LISP, where you can create objects and simply forget about them when you don’t need them any more, and a background process will automatically reclaim the storage at some point. The trouble is, that reclamation process (the “garbage collector”) tends to be the source of performance bottlenecks in the system. Not to mention that the memory usage of your program can grow to fill all available space, unless you impose arbitrary limits on it. Languages like Perl and Python use a hybrid model, where objects have reference counts attached to them, keeping track of how many other objects or variables still point to them, so they can be automatically freed when the count goes to zero. There are cases where this isn’t enough, and in those cases a full garbage-collection process kicks in. One benefit that I certainly observe with this is that memory usage for a program can remain reasonable, even after it has been running for a long time. Rust avoids the whole issue in a clever way, by having the compiler enforce memory-ownership restrictions in the language itself, so memory can be correctly allocated and freed without resorting to a garbage collector. The result is that Rust can achieve significantly higher performance than Go, while avoiding most of the attendant risks of dumping the whole responsibility for memory management on the programmer, as is done in languages like C++ and C.

NZ Domain Costs Going Up
by Lawrence D'Oliveiro 29 Feb '20

29 Feb '20

InternetNZ is seeing fewer registrations of .nz domains, so it is raising prices <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=123126…>. Apparently some are using .kiwi, and others are simply setting up pages on Facebook instead.

How Melissa Di Donato Is Going To Reinvent SUSE
by Peter Reutemann 28 Feb '20

28 Feb '20

'SUSE is one of the oldest open source companies and the first to market Linux for the enterprise. Even though it has undergone several acquisitions and a merger, it remains a strong player in the business. It has maintained its integrity and core values around open source. It continues to rely on its tried-and-tested Linux business and European markets, and generally shies away from making big moves taking big risks. Until now. SUSE appointed Melissa Di Donato as its first female CEO. She is making some serious changes to the company, from building a diverse and inclusive culture to betting on emerging technologies and taking risks. Soon after taking the helm last year, Di Donato spent the first few months traveling around the globe to meet SUSE teams and customers and get a better sense of the perception of the market about the company. Just like Red Hat CEO Jim Whitehurst, Di Donato didn’t come to the company from an open source background. She had spent the last 25 years of her career as a SUSE customer, so she did have an outsider’s perspective of the company. “I am not interested in what SUSE was when I joined. I am more interested in what we want to become,” she said.' -- source: https://www.linux.com/topic/open-source/how-melissa-di-donato-is-going-to-r… 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/

Raspberry Pi 4 Linux Computer Gets Twice the RAM and USB-C Power Fix
by Peter Reutemann 28 Feb '20

28 Feb '20

'Brian Fagioli, writing for BetaNews: The Raspberry Pi line has provided great little Linux computers to nerds -- its low price and small size makes it ideal for tinkering and doing projects. But also, the device has proven to be a solid media device, wonderful for watching videos and emulating classic video games. In other words, it has been a very versatile computer, serving as many things to many people. With the release of the Raspberry Pi 4, however, it finally became powerful enough to serve as a true desktop computer. By installing a Linux distribution, some people can use it for day-to-day computer use, such as web browsing, playing media, and word processing. Unfortunately, the $35 base model came with a paltry 1GB of RAM. Today, this changes, as the company has dropped the price of the 2GB version to $35, effectively doubling the memory for the base model.' -- source: https://linux.slashdot.org/story/20/02/27/1520258 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/

Quotes From RSA
by Lawrence D'Oliveiro 27 Feb '20

27 Feb '20

Among the plethora of pithy apothegms from the panel of crypto experts at the RSA Conference <https://www.theregister.co.uk/2020/02/26/rsa_2020_panel_discussion/>: “I give fusion power a higher chance of succeeding than quantum computing.” -- Ron Rivest “Blockchain is the wrong security technology for voting. I like to think of it as bringing a combination lock to a kitchen fire.” -- Ron Rivest “Intelligence is not about playing fair, it is about succeeding.” -- Whitfield Diffie, on the Crypto AG backdooring saga “I would like to understand how right to be forgotten could be for anything except to keep the little people in line. It is not the right to be forgotten by the secret police.” -- Whitfield Diffie Of course, there were some dissenting opinions to that last one ...
