Stopping Alert Volume Going To 100%

by Lawrence D'Oliveiro

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

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.

Microsoft Fixes Notepad

by Lawrence D'Oliveiro

Windows Notepad has never been able to handle any newline convention other than the old DOS/Windows/CP/M one (CR-LF). Now, after so many decades, Microsoft has finally decided to give it “universal newline” capability, so it can handle lines ending in LF-only (Unix/Linux) and CR-only (old MacOS) <http://www.theregister.co.uk/2018/05/08/windows_notepad_unix_macos_line_end…>. Gee, I wonder how many lines of code that took...

Aussie Law >> Maths

by Lawrence D'Oliveiro

"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…>

Wellywood’s Digital Edge Has Dulled

by Lawrence D'Oliveiro

You may have seen an item in the news lately about a report into the large amount of subsidies that the Government puts into the local film industry. This latest report says that these subsidies pay off in jobs and revenue elsewhere, but independent reviewers question this, saying such conclusions are very sensitive to initial assumptions <https://www.nzherald.co.nz/business/news/article.cfm?c_id=3&objectid=120795…>. This extract from one of the linked documents caught my eye: Weta Digital executives ... considered that 10 years ago they were at the forefront of technology and that studios were forced to use them to achieve particular effects, they said that this is no longer true: “the degrees of difference in technology are almost imperceptible”. It is no longer technical capability that wins work, it is price point; they consider themselves a price taker. “If the grant were to disappear tomorrow it would call into question the business itself…the subsidy allows us to compete.” There is “no scenario” where the US studios would pay 20% more for Weta Digital than its competitors. VFX have long been a commodity; it’s actually surprising that Weta Digital has managed to last this long, compared to, say, Rhythm & Hues, which went bust shortly after winning an Oscar for “Life Of Pi” <http://www.fresnobee.com/news/nation-world/national/article128729769.html>. I guess it’s all down to those Government subsidies...

Android Bug Allows Geolocation Tracking of Users

by Peter Reutemann

'Researchers have discovered a weakness in all version of Android except 9, the most recent release, that can allow an attacker to gather sensitive information such as the MAC address and BSSID name and pinpoint the location of an affected device. The vulnerability is a result of the way that Android broadcasts device information to apps installed on a device. The operating system uses a mechanism known as an intent to send out information between processes or applications, and some of the information about the device's WiFi network interface sent via a pair of intents can be used by an attacker to track a device closely. A malicious app -- or just one that is listening for the right broadcasts from Android -- would be able to identify any individual Android device and geolocate it. An attacker could use this weaknesses to track a given device, presumably without the user's knowledge. Although Android has had MAC address randomization implemented since version 6, released in 2015, Yakov Shafranovich of Nightwatch Cybersecurity said his research showed that an attacker can get around this restriction.' -- source: https://yro.slashdot.org/story/18/08/30/1725225 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/

What Dropbox Dropping Linux Support Says

by Peter Reutemann

'Jack Wallen, writing for TechRepublic: For a company to support Linux, they have to consider supporting: Multiple file systems, multiple distributions, multiple desktops, multiple init systems, multiple kernels. If you're an open source developer, focusing on a single distribution, that's not a problem. If you're a company that produces a product (and you stake your living on that product), those multiple points of entry do become a problem. Let's consider Adobe (and Photoshop). If Adobe wanted to port their industry-leading product to Linux, how do they do that? Do they spend the time developing support for ext4, btrfs, Ubuntu, Fedora, GNOME, Mate, KDE, systemd? You see how that might look from the eyes of any given company? It becomes even more complicated when companies consider how accustomed to the idea of "free" (as in beer) Linux users are. Although I am very willing to pay for software on Linux, it's a rare occasion that I do (mostly because I haven't found a piece of must-have software that has an associated cost). Few companies will support the Linux desktop when the act of supporting means putting that much time and effort into a product that a large cross-section of users might wind up unwilling to pay the price of admission. That's not to say every Linux user is unwilling to shell out the cost for a piece of software. But many won't.' -- source: https://linux.slashdot.org/story/18/08/29/0949228 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/

The Linux Foundation Is Changing The Fabric Of Networking

by Peter Reutemann

'Will Townsend, a senior analyst at Moor Insights & Strategy research firm, writes: As it relates to networking, the Linux Foundation is currently focused on a number of projects that are bringing top networking vendors, operators, service providers, and users together. Among the top initiatives are the Open Network Automation Platform (ONAP) and Data Plane Development Kit (DPDK). In this article, I would like to dive into both of these initiatives and share my perspective on how each is transforming the nature of networking [Editor's note: the website may have auto-playing videos; an alternative link was not available]. It makes sense that ONAP's releases are named after global cities, considering the platform's growing global footprint. ONAP is aimed at bringing real-time automation and orchestration to both physical and virtualized network functions. The first release in the fall of 2017, named Amsterdam, delivered a unified architecture for providing closed-loop networking automation. The underlying framework ensured a level of modularity to facilitate future functionality as well as standards harmonization and critical upstream partner collaboration. Initial use cases centered on Voice Over LTE (VoLTE) services as well as Virtualized Consumer Premise Equipment (vCPE). Both are extremely cost disruptive from a deployment and management perspective and deliver enhanced service provider agility. What I find extremely compelling is that Amsterdam was only an eight-month development cycle from start to release. That's an amazing feat even in the fast-paced technology industry. [...] DPDK was an effort initially led by Intel at its inception nearly eight years ago, but became a part of the Linux Foundation back in 2017. At a high level, the technology accelerates packet processing workloads running on a variety of CPU architectures. DPDK is aimed at improving overall network performance, delivering enhanced encryption for improved security and optimizing lower latency applications that require lightning-fast response time. The transformative power of 5G networks lies in their potential to deliver low latency for applications such as augmented/virtual reality and self-driving cars -- DPDK will further extend that performance for next-generation wireless wide area networks. I had the opportunity recently to speak to project chair Jim St. Leger after the fifth DPDK release, and I was impressed with the depth and breadth of the open source project. Over 25 companies and 160 technologists are involved in advancing the effort. With the proliferation of data, cord cutting at home, and growing consumption of video over wired and wireless networks, high-quality compression techniques will dramatically improve performance and reliability. DPDK appears to be poised to contribute significantly to that effort.' -- source: https://linux.slashdot.org/story/18/08/29/1646231 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/
