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.

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.

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.

Incognito Mode Detection Still Works in Chrome Despite Promise To Fix
by Peter Reutemann 22 Jul '20

22 Jul '20

'Websites are still capable of detecting when a visitor is using Chrome's incognito (private browsing) mode, despite Google's efforts last year to disrupt the practice. From a report: It is still possible to detect incognito mode in Chrome, and all the other Chromium-based browsers, such as Edge, Opera, Vivaldi, and Brave, all of which share the core of Chrome's codebase. Furthermore, developers have taken the scripts shared last year and have expanded support to non-Chrome browsers, such as Firefox and Safari, allowing sites to block users in incognito mode across the board. Currently, there is no deadline for a new Chrome update to block incognito mode detections, however, today, Google might be interested more than ever in fixing this issue' -- source: https://yro.slashdot.org/story/20/06/04/1857211 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 Removes 25 Android Apps Caught Stealing Facebook Credentials
by Peter Reutemann 01 Jul '20

01 Jul '20

'Google has removed this month 25 Android apps from the Google Play Store that were caught stealing Facebook credentials. From a report: Before being taken down, the 25 apps were collectively downloaded more than 2.34 million times. The malicious apps were developed by the same threat group and despite offering different features, under the hood, all the apps worked the same. According to a report from French cyber-security firm Evina shared with ZDNet today, the apps posed as step counters, image editors, video editors, wallpaper apps, flashlight applications, file managers, and mobile games. The apps offered a legitimate functionality, but they also contained malicious code. Evina researchers say the apps contained code that detected what app a user recently opened and had in the phone's foreground. If the app was Facebook, the malicious app would overlay a web browser window on top of the official Facebook app and load a fake Facebook login page (see image below: blue bar = actual Facebook app, black bar = phishing page).' -- source: https://tech.slashdot.org/story/20/06/30/1411202 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/

Android's AirDrop Competitor Is Coming Soon
by Peter Reutemann 01 Jul '20

01 Jul '20

'Android's long-awaited "Nearby Sharing" feature, which allows you to share files between Android devices wirelessly, is rolling out to beta testers. Android Police reports: Nearby Sharing may appear slightly differently depending on the type of content you try to share. In all cases, it shows up as an app in the apps list on the share sheet, but you may also get a smaller prompt just under the content preview, more like it did in the previous Android 11 video leak. We tested it on a Pixel 4 XL and Pixel 3a running Android 10, but the appearance may also vary on other versions of Android. Note that Nearby Share works for both files like photos or videos, as well as other shareable content like Tweets and URLs. It probably works with a lot of things. Select Nearby Share in the share sheet as the target, and you're prompted to turn on the feature, if it's the first time you've used it. The quick setup process lets you configure your default device name and device visibility settings, though those can also be changed later. Once you have it enabled, Nearby Sharing starts looking for other nearby devices. The interface is pretty simple: A big X in the top left corner backs you out, your avatar on the right takes you to a settings pane that lets you configure things like your device name, visibility, and which mechanism to use to make the transfer (i.e., whether to use your internet connection for small files, to stick to Wi-Fi, or to always share offline). Google says Nearby Share is currently in limited testing via the Play Services beta: "We're currently conducting a beta test of a new Nearby Share feature that we plan to share more information on in the future. Our goal is to launch the feature with support for Android 6+ devices as well as other platforms."' -- source: https://mobile.slashdot.org/story/20/06/30/2014259 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/

Apple Declined To Implement 16 Web APIs in Safari Due To Privacy Concerns
by Peter Reutemann 30 Jun '20

30 Jun '20

'Apple said last week that it declined to implement 16 new web technologies (Web APIs) in Safari because they posed a threat to user privacy by opening new avenues for user fingerprinting. Technologies that Apple declined to include in Safari because of user fingerprinting concerns include: Web Bluetooth - Allows websites to connect to nearby Bluetooth LE devices. Web MIDI API - Allows websites to enumerate, manipulate and access MIDI devices. Magnetometer API - Allows websites to access data about the local magnetic field around a user, as detected by the device's primary magnetometer sensor. Web NFC API - Allows websites to communicate with NFC tags through a device's NFC reader. Device Memory API - Allows websites to receive the approximate amount of device memory in gigabytes. Network Information API - Provides information about the connection a device is using to communicate with the network and provides a means for scripts to be notified if the connection type changes. Battery Status API - Allows websites to receive information about the battery status of the hosting device. Web Bluetooth Scanning - Allows websites to scan for nearby Bluetooth LE devices. Ambient Light Sensor - Lets websites get the current light level or illuminance of the ambient light around the hosting device via the device's native sensors. [...] The vast majority of these APIs are only implemented in Chromium-based browsers, and very few on Mozilla's platform. Apple claims that the 16 Web APIs above would allow online advertisers and data analytics firms to create scripts that fingerprint users and their devices.

A decidedly non-Linux distro walkthrough: Haiku R1/beta2
by Peter Reutemann 30 Jun '20

30 Jun '20

'Earlier this month, the Haiku project released the second beta of its namesake operating system, Haiku. Haiku is the reimagining of a particularly ambitious, forward-looking operating system from 1995—Be, Inc.'s BeOS. BeOS was developed to take advantage of Symmetrical Multi-Processing (SMP) hardware using techniques we take for granted today—kernel-scheduled pre-emptive multitasking, ubiquitous multithreading, and BFS—a 64-bit journaling filesystem of its very own. [...] In June 2020—nineteen years after OpenBeOS was born, and sixteen after its rename to Haiku—the project released its second beta distribution. The project still adheres to backward application compatibility with 1990s BeOS—although only in its 32-bit version, which I did not test.' -- source: https://arstechnica.com/gadgets/2020/06/a-decidedly-non-linux-distro-walkth… 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/
