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>.

How Qualcomm Shook Down The Cell Phone Industry For Almost 20 Years

by Lawrence D'Oliveiro

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.

Security Is Always Down To The Weakest Link

by Lawrence D'Oliveiro

Nice non-paywalled report <https://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=12235615> into how the National Party (and others) were able to obtain supposedly-confidential details of today’s Budget announcements. In summary, a “clone” was made of the Treasury website, containing the Budget info, that was supposed to be swapped for the current production site later today. It was not publicly accessible, at least directly. However, the search function on the public site was inadvertently sucking up the confidential info from the clone server as well, and carefully-worded searches would reveal bits of such info as search context, even if the actual documents being indexed were not accessible in full. The Police have decided that, even though such leaks are considered a serious matter, the accesses were “not unlawful”. Which seems a refreshing change from, say, the UK, where someone was prosecuted and jailed some years ago just for putting “../” into a URL ...

Dell Begins Pre-Installing Linux On Range of Precision Laptops

by Peter Reutemann

'"While Linux-preloaded laptops have been available for years from smaller companies, and have represented a fraction of their own sales with the much-admired XPS 13 developer model, Dell now offers a range of Precision models pre-installed with Ubuntu Linux," writes Slashdot reader Freshly Exhumed. Phoronix reports: At the start of May Dell announced an Ubuntu Linux option for their entry-level ~$700 Precision laptop while now they are closing out May by offering up Ubuntu 18.04 LTS on their higher-tier Precision laptop models. Ubuntu Linux has landed for the rest of Dell's current generation Precision mobile workstation line-up with support for the Precision 5540, 7540, and 7740. The Precision 5540 offers options of Xeon E or 9th Gen Core CPUs with up to 64GB of RAM and options for a NVIDIA Quadro T2000. The Precision 7540/7740 meanwhile are more powerful mobile workstations with supporting up to 128GB of ECC RAM and latest generation processors. The Precision 7740 model can also accomodate NVIDIA Quadro RTX 5000 series graphics. Additional details can be found via this blog post by Dell's Barton George.' -- source: https://linux.slashdot.org/story/19/05/30/2154256 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/

Advanced Linux backdoor found in the wild escaped AV detection

by Peter Reutemann

'Researchers say they’ve discovered an advanced piece of Linux malware that has escaped detection by antivirus products and appears to be actively used in targeted attacks. HiddenWasp, as the malware has been dubbed, is a fully developed suite of malware that includes a trojan, rootkit, and initial deployment script, researchers at security firm Intezer reported on Wednesday. At the time Intezer’s post went live, the VirusTotal malware service indicated Hidden Wasp wasn’t detected by any of the 59 antivirus engines it tracks, although some have now begun to flag it. Time stamps in one of the 10 files Intezer analyzed indicated it was created last month. The command and control server that infected computers report to remained operational at the time this article was being prepared. Some of the evidence analyzed—including code showing that the computers it infects are already compromised by the same attackers—indicated that HiddenWasp is likely a later stage of malware that gets served to targets of interest who have already been infected by an earlier stage. It’s not clear how many computers have been infected or how any earlier related stages get installed. With the ability to download and execute code, upload files, and perform a variety of other commands, the purpose of the malware appears to be to remotely control the computers it infects. That's different from most Linux malware, which exists to perform denial of service attacks or mine cryptocurrencies.' -- source: https://arstechnica.com/information-technology/2019/05/advanced-linux-backd… 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/

Chinese Military To Replace Windows OS Amid Fears of US Hacking

by Peter Reutemann

'Amidst an escalating trade war and political tensions with the US, Beijing officials have decided to develop a custom operating system that will replace the Windows OS on computers used by the Chinese military. From a report: The decision, while not made official through the government's normal press channels, was reported earlier this month by Canada-based military magazine Kanwa Asian Defence. Per the magazine, Chinese military officials won't be jumping ship from Windows to Linux but will develop a custom OS. Thanks to the Snowden, Shadow Brokers, and Vault7 leaks, Beijing officials are well aware of the US' hefty arsenal of hacking tools, available for anything from smart TVs to Linux servers, and from routers to common desktop operating systems, such as Windows and Mac. Since these leaks have revealed that the US can hack into almost anything, the Chinese government's plan is to adopt a "security by obscurity" approach and run a custom operating system that will make it harder for foreign threat actors -- mainly the US -- to spy on Chinese military operations.' -- source: https://news.slashdot.org/story/19/05/28/1613221 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/

W3C and WHATWG Sign Agreement To Collaborate on a Single Version of HTML and DOM

by Peter Reutemann

'W3C and the WHATWG signed an agreement today to collaborate on the development of a single version of the HTML and DOM specifications. >From a blog post: The Memorandum of Understanding jointly published as the WHATWG/W3C Joint Working Mode gives the specifics of this collaboration. This is the culmination of a careful exploration effective partnership mechanisms since December 2017 after the WHATWG adopted many shared features as their work-mode and an IPR policy. The HTML Working Group which we will soon recharter will assist the W3C community in raising issues and proposing solutions for the HTML and DOM specifications, and bring WHATWG Review Drafts to Recommendation. Motivated by the belief that having two distinct HTML and DOM specifications claiming to be normative is generally harmful for the community, and the mutual desire to bring the work back together, W3C and WHATWG agree to the following terms: W3C and WHATWG work together on HTML and DOM, in the WHATWG repositories, to produce a Living Standard and Recommendation/Review Draft-snapshots. WHATWG maintains the HTML and DOM Living Standards. W3C facilitates community work directly in the WHATWG repositories (bridging communities, developing use cases, filing issues, writing tests, mediating issue resolution). W3C stops independent publishing of a designated list of specifications related to HTML and DOM and instead will work to take WHATWG Review Drafts to W3C Recommendations.' -- source: https://tech.slashdot.org/story/19/05/28/1353243 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's Chrome Becomes Web 'Gatekeeper' and Rivals Complain

by Peter Reutemann

'Few home-grown Google products have been as successful as Chrome. Launched in 2008, it has more than 63% of the market and about 70% on desktop computers, according to StatCounter data. Mozilla's Firefox is far behind, while Apple's Safari is the default browser for iPhones. Microsoft's Internet Explorer and Edge browsers are punchlines. From a report: Google won by offering consumers a fast, customizable browser for free, while embracing open web standards. Now that Chrome is the clear leader, it controls how the standards are set. That's sparking concern Google is using the browser and its Chromium open-source underpinnings to elbow out online competitors and tilt entire industries in its favor. Most major browsers are now built on the Chromium software code base that Google maintains. Opera, an indie browser that's been used by techies for years, swapped its code base for Chromium in 2013. Even Microsoft is making the switch this year. That creates a snowball effect, where fewer web developers build for niche browsers, leading those browsers to switch over to Chromium to avoid getting left behind. This leaves Chrome's competitors relying on Google employees who do most of the work to keep Chromium software code up to date. Chromium is open source, so anyone can suggest changes to it, but the majority of programmers who approve contributions are Google employees, and any major disagreements get settled by a small circle of senior Google employees. Chrome is so ascendant these days that web developers often don't bother to test their sites on competing browsers. Google services including YouTube, Docs and Gmail sometimes don't work as well on rival browsers, sending frustrated users to Chrome. Instead of just another ship slicing through the sea of the web, Chrome is becoming the ocean.' -- source: https://developers.slashdot.org/story/19/05/28/1845238 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/

Huawei's Android Replacement OS Will Launch in June, Company Exec Says

by Peter Reutemann

'Huawei's home-grown operating system -- codenamed HongMeng -- that's set to replace Android once the Huawei ban from Google comes into full effect, will be commercially rolled out next month, a Middle East head for the firm revealed exclusively to TechRadar Middle East. From a report: On May 20, Google announced that it would partially cut off Huawei devices from its Android operating system but was given an extension till August 19 by the US White House. "Huawei knew this was coming and was preparing. The OS was ready in January 2018 and this was our 'Plan B'," said Alaa Elshimy, Managing Director and Vice President of Huawei Enterprise Business Group Middle East. "We did not want to bring the OS to the market as we had a strong relationship with Google and others and did not want to ruin the relationship. Now, we are rolling it out next month' -- source: https://tech.slashdot.org/story/19/05/28/1524239 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/
