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>.

Does Wi-Fi Security Really Matter?
by Lawrence D'Oliveiro 11 Apr '19

11 Apr '19

Seems the Wi-Fi Alliance is having yet another crack at coming up with a really secure protocol, this time to be called WPA3 <http://www.theregister.co.uk/2018/01/09/wi_fi_wpa3/>. Does anybody care? Remember that on the Internet, security is implemented between the endpoints, the protocols are designed not to care that everything in-between might be pawed through by eavesdroppers, or even active attackers trying to inject fake data.

"The laws of Australia prevail in Australia, I can assure you of that," [Malcolm Turnbull] said on Friday. "The laws of mathematics are very commendable, but the only law that applies in Australia is the law of Australia." <https://www.techdirt.com/articles/20170714/10385237789/aussie-prime-ministe…>

meeting next month
by Peter Reutemann 13 Feb '18

13 Feb '18

Hi everyone At the last meeting, Ian suggested to have cryptocurrencies (https://en.wikipedia.org/wiki/Cryptocurrency) as topic for our meeting next month. One aspect is the increasing amount of power that is consumed in order to mine "coins". The other interesting aspect introduced by, but not limit to, cryptocurrencies is the concept of the blockchain (https://en.wikipedia.org/wiki/Blockchain) an open, distributed ledger of transactions. Is there interest? Any volunteers to talk about something regarding this topic (history, current status, etc)? 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/

LibreOffice 6.0 Released: Features Superior Microsoft Office Interoperability, OpenPGP Support
by Peter Reutemann 31 Jan '18

31 Jan '18

'LibreOffice 6.0 comes two and a half years after the LibreOffice 5.x series, and it's the biggest release of the open-source and cross-platform office suite so far. It introduces a revamped design with new table styles, improved Notebookbars, new gradients, new Elementary icons, menu and toolbar improvements, and updated motif/splash screen. LibreOffice 6.0 offers superior interoperability with Microsoft Office documents and compatibility with the EPUB3 format by allowing users to export ODT files to EPUB3. It also lets you import your AbiWord, Microsoft Publisher, PageMaker, and QuarkXPress documents and templates thanks to the implementation of a set of new open-source libraries contributed by the Document Liberation project. Many great improvements were made to the OOXML and ODF filters, as well as in the EMF+, Adobe Freehand, Microsoft Visio, Adobe Pagemaker, FictionBook, Apple Keynote, Pages, and Numbers, as well as Quattro Pro import functionality, and to the XHTML export. LibreOffice Online received numerous improvements as well in this major release of LibreOffice.' -- source: https://news.slashdot.org/story/18/01/31/1422245 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/

Samsung Surpasses Intel To Become the World's Largest Chipmaker
by Peter Reutemann 31 Jan '18

31 Jan '18

'Samsung Electronics just knocked Intel off its perch as the world's biggest chipmaker by revenue, a spot the U.S. company has held since 1992. From a report: On Tuesday, Samsung reported 2017 chip sales of $69 billion, blowing past Intel's $63 billion from last year. The switch underlines how Samsung has transformed itself from a maker of cheap televisions into a pervasive supplier of key components in smartphones and other modern computing devices. It's also a testament to the growth of memory chips, Samsung's main market. Intel, whose processors are the heart of about 90 percent of the world's computers, didn't have a bad year. Sales grew 6 percent. Success in computers is no longer enough, though. Memory chips, a market Intel only recently got back into, are now crucial parts of smartphones, which easily outsell PCs these days. Memory chips are also finding their way into a range of new devices such as cars. One of the ironies of Samsungâ(TM)s success in memory is that itâ(TM)s a business Intel created in the 1960s.' -- source: https://slashdot.org/story/18/01/31/1516212 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 Chrome To Feature Built-In Image Lazy Loading
by Peter Reutemann 31 Jan '18

31 Jan '18

'Future versions of Google Chrome will feature built-in support for lazy loading, a mechanism to defer the loading of images and iframes if they are not visible on the user's screen at load time. This system will first ship with Chrome for Android and Google doesn't rule out adding it to desktop versions if tests go as planned. The feature is called Blink LazyLoad, and as the name hints, it will implement the principle of "lazy loading" inside Chrome itself. Google engineers reported page load speed improvements varying from 18% to 35%, depending on the underlying network. Other browser makers have been notified of the Chrome team's plan, but none have provided input if they plan to implement a similar feature. Compared to most JS-based lazy loading scripts that only target images, Google implementation will also target iframes.' -- source: https://tech.slashdot.org/story/18/01/31/180234 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/

MPEG Founder Says the MPEG Business Model Is Broken
by Peter Reutemann 30 Jan '18

30 Jan '18

'Leonardo Chiariglione, the founder and chairman of MPEG, argues on his blog that the current MPEG business model is broken. He writes, "Thanks to [MPEG's] 'business model' that can be simply described as: produce standards having the best performance as a goal, irrespective of the IPR involved. Because MPEG standards are the best in the market and have an international standard status, manufacturers/service providers get a global market of digital media products, services and applications, and end users can seamless communicate with billions of people and access millions of services. Patent holders who allow use of their patents get hefty royalties with which they can develop new technologies for the next generation of MPEG standards. A virtuous cycle everybody benefits from." But, he argues, the MPEG model is now in crisis because the forthcoming AV1 video format from the Alliance for Open Media means that "everybody realizes that the old MPEG business model is broke, all the investments (collectively hundreds of millions USD) made by the industry for the new video codec [HEVC] will go up in smoke and AOM's royalty free model will spread to other business segments as well." Chiariglione goes on to explain what can be done: "The first action is to introduce what I call 'fractional options.' ISO envisages two forms of licensing: Option 1, i.e. royalty free and Option 2, i.e. FRAND, which is taken to mean 'with undetermined license.' We could introduce fractional options in the sense that a proposer could indicate that the technology be assigned to a specifically identified profile with an 'industry license' (defined outside MPEG) that does not contain monetary values. For instance, one such license could be 'no charge' (i.e. Option 1), another could be targeted to the OTT market etc." "The second action, not meant to be alternative to the first, is to streamline the MPEG standard development process. Within this a first goal is to develop coding tools with 'clear ownership,' unlike today's tools which are often the result of contributions with possibly very different weights. A second goal is not to define profiles in MPEG. A third goal could be to embed in the standard the capability to switch coding tools on and off."' -- source: https://news.slashdot.org/story/18/01/30/0419222 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/

Is This The Hawaii Civil Defence Missile Alert UI?
by Lawrence D'Oliveiro 30 Jan '18

30 Jan '18

Remember the alert about the incoming missile in Hawaii that turned out to be nonsense? This <https://arstechnica.com/information-technology/2018/01/the-interface-to-sen…> is apparently what the user interface looks like for the system that sends out both test and genuine alerts. It looks like a web page with a random assortment of links. Just off the top of my head, not claiming to be a UI expert here, but I would have a big title across the top of the screen saying either “TEST MODE” or “LIVE MODE” (the latter red, and blinking). Then have a single set of options below, appropriate to the active mode. Even go one better, and do what Japanese railway locomotive drivers do as they see signs at the side of the track: say out loud what the signs mean, before taking appropriate action.

The SCO Vs IBM Zombie Shambles On
by Peter Reutemann 29 Jan '18

29 Jan '18

'At the end of last October, the 10th Circuit issued an opinion overturning the lower court's summary judgement in favor of IBM on one of SCO's claims, sending it back to the lower court for trial. Shortly thereafter, IBM filed for a re-hearing en banc. On January 2nd, the 10th circuit essentially denied IBM's request, issuing a slightly revised opinion with the same conclusions and result. The charge being reheard accuses IBM of "stealing and improperly using [SCO's] source code to strengthen its own operating system, thereby committing the tort of unfair competition by means of misappropriation" -- though that charged is based on an implied duty that SCO says IBM incurred by entering into a development relationship with SCO. "SCO believes that IBM merely pretended to go along with the arrangement in order to gain access to Santa Cruz's coveted source code." The court's 46-page document adds that "We are now almost fifteen years into this litigation."' -- source: https://yro.slashdot.org/story/18/01/29/0213203 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/
