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.

Virtual meetings?
by Peter Reutemann 24 Apr '20

24 Apr '20

Hi everyone Our last meeting moved to virtual Google Hangout on short notice, which probably explained the low turnout. My question is, whether speakers and attendees would be willing to move to virtual ones, to keep our little community together and going? The last meeting was done with Google Hangouts, as it allows sharing the screen as well. Doesn't have to be Hangouts, it was simply convenient as a lot of people have gmail accounts. Open to viable alternatives. Stay safe!

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.

Firefox To Remove Support For the FTP Protocol
by Peter Reutemann 16 Apr '20

16 Apr '20

'Mozilla has announced plans to remove support for the FTP protocol from Firefox. Going forward, users won't be able to download files via the FTP protocol and view the content of FTP links/folders inside the Firefox browser. From a report: "We're doing this for security reasons," said Michal Novotny, a software engineer at the Mozilla Corporation, the company behind the Firefox browser. "FTP is an insecure protocol and there are no reasons to prefer it over HTTPS for downloading resources," he said. "Also, a part of the FTP code is very old, unsafe and hard to maintain and we found a lot of security bugs in it in the past." Novotny says Mozilla plans to disable support for the FTP protocol with the release of Firefox 77, scheduled for release in June this year.' -- source: https://news.slashdot.org/story/20/03/19/169246 There's always FileZilla...

Linux Mint 20 is 64-bit Only, Based on Ubuntu 20.04, and Named 'Ulyana'
by Peter Reutemann 01 Apr '20

01 Apr '20

'Today, we learn some new details about the upcoming Linux Mint 20. While most of the newly revealed information is positive, there is one thing that is sure to upset many Linux Mint users. First things first, Linux Mint 20 will be based on the upcoming Ubuntu 20.04. This shouldn't come as a surprise, as Mint only uses Long Term Support versions of Ubuntu, and 20.04 will be an LTS. We also now know the name of Linux Mint 20. The Mint team always uses female names, and this time they chose "Ulyana." This is apparently a Russian name meaning "youthful." So far, all of the news is positive, so what exactly will upset some users? The Linux Mint developers are finally dropping 32-bit support and will only produce 64-bit ISOs.' -- source: https://linux.slashdot.org/story/20/03/31/1842216 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/

Zoom Meetings Aren't End-to-End Encrypted, Despite Misleading Marketing
by Peter Reutemann 01 Apr '20

01 Apr '20

'Zoom, the video conferencing service whose use has spiked amid the Covid-19 pandemic, claims to implement end-to-end encryption, widely understood as the most private form of internet communication, protecting conversations from all outside parties. In fact, Zoom is using its own definition of the term, one that lets Zoom itself access unencrypted video and audio from meetings. With millions of people around the world working from home in order to slow the spread of the coronavirus, business is booming for Zoom, bringing more attention on the company and its privacy practices, including a policy, later updated, that seemed to give the company permission to mine messages and files shared during meetings for the purpose of ad targeting. Still, Zoom offers reliability, ease of use, and at least one very important security assurance: As long as you make sure everyone in a Zoom meeting connects using "computer audio" instead of calling in on a phone, the meeting is secured with end-to-end encryption, at least according to Zoom's website, its security white paper, and the user interface within the app. But despite this misleading marketing, the service actually does not support end-to-end encryption for video and audio content, at least as the term is commonly understood. Instead it offers what is usually called transport encryption.' -- source: https://it.slashdot.org/story/20/03/31/1526250 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/

Zoom is Leaking Peoples' Email Addresses and Photos To Strangers
by Peter Reutemann 01 Apr '20

01 Apr '20

'Popular video-conferencing Zoom is leaking personal information of at least thousands of users, including their email address and photo, and giving strangers the ability to attempt to start a video call with them through Zoom. From a report: The issue lies in Zoom's "Company Directory" setting, which automatically adds other people to a user's lists of contacts if they signed up with an email address that shares the same domain. This can make it easier to find a specific colleague to call when the domain belongs to an individual company. But multiple Zoom users say they signed up with personal email addresses, and Zoom pooled them together with thousands of other people as if they all worked for the same company, exposing their personal information to one another.' -- source: https://yro.slashdot.org/story/20/03/31/201237 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/

Internet Pioneer Vint Cerf Tests Positive For Covid-19
by Peter Reutemann 31 Mar '20

31 Mar '20

'Tech pioneer Vint Cerf, one of the co-creators of the modern internet, has tested positive for covid-19, according to a tweet Cerf sent out Monday morning. The 76-year-old tweeted out a clip from HBO's Last Week Tonight with John Oliver about the U.S. response to the global pandemic. "I tested positive for COVID-19 and am recovering," Cerf tweeted. "Listen to what John Oliver has to say about our national response so far." Cerf helped create the modern internet in the 1970s while working at UCLA with other pioneers like Bob Kahn and Leonard Kleinrock. Cerf worked on packet switching for the APRANET under Kleinrock and TCP/IP protocols with ARPA (now DARPA), the plumbing that makes the internet function. DARPA tweeted its support of Cerf, telling him to get well soon.' -- source: https://science.slashdot.org/story/20/03/30/214250 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/

WireGuard VPN makes it to 1.0.0—and into the next Linux kernel
by Peter Reutemann 31 Mar '20

31 Mar '20

'We've been anticipating WireGuard's inclusion into the mainline Linux kernel for quite some time—but as of Sunday afternoon, it's official. Linus Torvalds released the Linux 5.6 kernel, which includes (among other things) an in-tree WireGuard. Phoronix has a great short list of the most interesting new features in the 5.6 kernel, as well as a longer "everything list" for those who want to make sure they don't miss anything. If this is the first time you're hearing about WireGuard, the TL;DR is that it's a relatively new VPN (Virtual Private Network) application that offers a leaner codebase, easier configuration, faster connect times, and the latest and most thoroughly peer-reviewed and approved encryption algorithms. You can find a more detailed introduction in our initial August 2018 coverage.' -- source: https://arstechnica.com/gadgets/2020/03/wireguard-vpn-makes-it-to-1-0-0-and… 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/

Public Crash Screens: Linux For A Change
by Lawrence D'Oliveiro 27 Mar '20

27 Mar '20

The Register runs a regular series of reports on public signage showing crash messages instead of the ones they are supposed to show. Usually these are Microsoft Windows messages, often for hilariously out-of-date versions of Windows. This one, for a change <https://www.theregister.co.uk/2020/03/24/bork_walmart/>, shows a Linux boot failure. But it is still a hilariously out-of-date version of Linux.

The exFAT Filesystem Is Coming To Linux -- Paragon Software's Not Happy About It
by Peter Reutemann 26 Mar '20

'When software and operating system giant Microsoft announced its support for inclusion of the exFAT filesystem directly into the Linux kernel back in August, it didn't get a ton of press coverage. But filesystem vendor Paragon Software clearly noticed this month's merge of the Microsoft-approved, largely Samsung-authored version of exFAT into the VFS for-next repository, which will in turn merge into Linux 5.7 -- and Paragon doesn't seem happy about it. Yesterday, Paragon issued a press release about European gateway-modem vendor Sagemcom adopting its version of exFAT into an upcoming series of Linux-based routers. Unfortunately, it chose to preface the announcement with a stream of FUD (Fear, Uncertainty, and Doubt) that wouldn't have looked out of place on Steve Ballmer's letterhead in the 1990s.' -- source: https://linux.slashdot.org/story/20/03/25/2136223 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 Play’s malicious app problem infects 1.7 million more devices
by Peter Reutemann 25 Mar '20

25 Mar '20

'Google Play, the company’s official repository for Android apps, has once again been caught hosting fraudulent and potentially malicious apps, with the discovery of more than 56 apps—many of them for children—that were installed on almost 1.7 million devices. Tekya is a family of malware that generates fraudulent clicks on ads and banners delivered by agencies including Google’s AdMob, AppLovin’, Facebook, and Unity. To give the clicks the air of authenticity, the well-obfuscated code causes infected devices to use Android’s “MotionEvent” mechanism to imitate legitimate user actions. At the time researchers from security firm Check Point discovered them, the apps went undetected by VirusTotal and Google Play Protect. Twenty-four of the apps that contained Tekya were marketed to children. Google removed all 56 of the apps after Check Point reported them. The discovery “highlights once again that the Google Play Store can still host malicious apps,” Check Point researchers Israel Wernik, Danil Golubenko, and Aviran Hazum wrote in a post published on Tuesday. “There are nearly 3 million apps available from the store, with hundreds of new apps being uploaded daily–making it difficult to check that every single app is safe. Thus, users cannot rely on Google Play’s security measures alone to ensure their devices are protected.”' -- source: https://arstechnica.com/information-technology/2020/03/found-malicious-goog… 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/

Meet the Chinese OS That's Trying To Shift the Country Off Windows
by Peter Reutemann 25 Mar '20

25 Mar '20

'China's homegrown operating systems haven't made much of a dent on the global stage. Now there's a Linux-based system that's aimed at weaning the country off Windows. From a report: UOS, or Unified Operating System, hit a new milestone after its first stable release in January: Union Tech's OS can now boot in 30 seconds on China-made chips. It's an important step as Chinese tech companies look to reduce their dependence on US-made software and hardware. The struggles of ZTE and Huawei illustrate this clearly: The former was reliant on chips made in the US to produce smartphones, while the latter has the difficult task of selling Android handsets outside China without Google apps or services. The "current international climate" has made it imperative for China to have its own foundational software to avoid being cut off by the US, said the general manager of Union Tech, Liu Wenhan. While Chinese operating systems currently account for less than 1% of the market, Liu said he expects them to grow to 20% to 30% in the future. Integrating homegrown Chinese chips could be the biggest accomplishment of UOS if it pans out. Although Chinese computer chips still don't approach the sophistication of those created by US-based companies, Union Tech said that it is actively working with Chinese chipmakers like Loongson and Sunway to facilitate the gradual replacement of American technology in the Chinese government and pillar industries. In December, Beijing ordered all government offices and public institutions to remove foreign computer equipment and software within three years.' -- source: https://tech.slashdot.org/story/20/03/24/1918223 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/

Microsoft Says Hackers Are Attacking Windows Users With a New Unpatched Bug
by Peter Reutemann 24 Mar '20

'Microsoft says attackers are exploiting a previously undisclosed security vulnerability found in all supported versions of Windows, including Windows 10. From a report: But the software giant said there is currently no patch for the vulnerability. The security flaw, which Microsoft deems "critical" -- its highest severity rating -- is found in how Windows handles and renders fonts, according to the advisory posted Monday. The bug can be exploited by tricking a victim into opening a malicious document. Once the document is opened -- or viewed in Windows Preview -- an attacker can remotely run malware, such as ransomware, on a vulnerable device. The advisory said that Microsoft was aware of hackers launching "limited, targeted attacks," but did not say who was launching the attacks or at what scale.' -- source: https://tech.slashdot.org/story/20/03/23/1846216 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/

WLUG meeting (virtual)
by Peter Reutemann 23 Mar '20

23 Mar '20

Hi everyone Thanks to Aarons tireless efforts, we can have our WLUG meeting despite COVID-19, though in virtual form via Youtube and Google Hangouts (see links below). As a refresher for the topic: The voice interface represents another big shift in user interfaces, and could be as big a shift as the shift from switches to terminals, the switch from terminals to windowed GUIs, or the switch from full computers to small touchscreen devices. Unfortunately, right now most of these devices are little more than a telephone for talking to a server in the cloud. That is a big problem for privacy, and presents the user with a false choice between access and privacy. Today's computers are capable of handling a verbal interface without requiring a cloud service to handle all of your requests. Aaron Chantrill is one of the developers on the Naomi Project, a free and open source voice assistant (https://projectnaomi.com) It is a plugin based system based on Jasper (http://jasperproject.github.io/) and depending on how the user chooses to configure it, can run totally offline. In this presentation, Aaron would like to introduce people to the Naomi Project, talk about the benefits of a verbal interface, talk about the current architectures of virtual assistants, and ways in which that architecture can be altered to provide better privacy, and also do a comparison of offline speech to text and text to speech solutions, including Pocketsphinx, Mozilla Deepspeech, Kaldi, and Julius. Finally, He will invite people to participate in building and improving Naomi. There is a lot to do and much of it is both engaging and cutting-edge. Aaron recorded a video of his presentation that you can watch here before the virtual meeting: https://youtu.be/8383A_t7iKQ The slides are available as well: https://github.com/aaronchantrill/NaomiPresentation/raw/master/Presentation… The Google Hangouts link for the Question & Answer session: https://hangouts.google.com/hangouts/_/calendar/ZHJhc2t5QGdtYWlsLmNvbQ.3j6l… Meetup link: https://www.meetup.com/WaikatoLinuxUsersGroup/events/269578787/ 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/
