Ah, The Joys Of Debian Unstable ...
by Lawrence D'Oliveiro 17 Oct '17

17 Oct '17

Did my (roughly) monthly system upgrades over the last couple of days. Debian has changed the default Python version for the “python3” command to 3.6. (And Blender now requires that version for building as well.) Didn’t notice anything broken until today, when I tried to print something on my HP inkjet. Turns out the various HP/CUPS-related packages with version number 3.17 want the system default Python to be 3.5, not 3.6. In situations like these, the first thing I have learned to try is to manually download older versions of packages from <http://ftp.debian.org/debian/> and install them with “dpkg -i”. For reference, these are the packages I downgraded: dpkg -i hplip-data_3.16.11+repack0-3_all.deb dpkg -i libhpmud0_3.16.11+repack0-3_amd64.deb dpkg -i libsane-hpaio_3.16.11+repack0-3_amd64.deb dpkg -i printer-driver-hpcups_3.16.11+repack0-3_amd64.deb dpkg -i hplip_3.16.11+repack0-3_amd64.deb And it worked. My printer now prints again. Presumably this will be sorted out in time for my next upgrade ...

qTox – An Open Source P2P Instant Messaging and VoIP App
by Peter Reutemann 16 Oct '17

16 Oct '17

'As you probably already know, GNU/Linux has no shortage of VoIP apps. We’ve written on Wire and Discord. And we even compiled a list of The 10 Best Instant Messaging Apps for Linux. Today, we’ve got a new app to add to our list of instant messaging apps and it goes by the name of qTox. qTox is a free and open source p2p instant messaging, audio and video calls app and is (apparently) the most feature-rich Tox client. As a powerful Tox client, it follows Tox’s design guidelines while maintaining a uniform UI/UX across all the major platforms. It is built with privacy as its paramount goal and the team has even made a public statement that user safety is their priority and nothing in the world can change that.' -- source: https://www.fossmint.com/qtox-an-open-source-p2p-instant-messaging-and-voip… 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/

by Peter Reutemann 16 Oct '17

16 Oct '17

'Interested in running Linux on Windows 10 with Windows Subsystem for Linux (WSL), but nervous about it being both a beta and only available in Windows 10 developer mode? Your worries are over. In the Windows 10 Fall Creators Update (WinFCU) WSL has graduated to being a Windows 10 feature that can be run by any user. Tested for over a year, WSL on WinFCU is bringing many new features to this combination of the Linux Bash shell and Windows. Besides WSL no longer being a beta or requiring users to be in developer mode, the new features include: Install Linux distros via the Windows Store - WSL now runs multiple Linux distros - WSL comes to Windows Server & Microsoft Azure VMs - WSL now supports USB/serial comms - Miscellaneous fixes and improvements Besides Ubuntu, the new WSL-supported Linux distros are SUSE's community openSUSE and its corporate SUSE Linux Enterprise Server (SLES). Fedora and other distros will arrive in the store shortly.' -- source: http://www.zdnet.com/article/windows-subsystem-for-linux-graduates-in-windo… 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/

Munich Plans New Vote on Dumping Linux For Windows 10
by Peter Reutemann 16 Oct '17

16 Oct '17

'The city of Munich has suggested it will cost too much to carry on using Linux alongside Windows, despite having spent millions of euros switching PCs to open-source software... "Today, with a Linux client-centric environment, we are often confronted with major difficulties and additional costs when it comes to acquiring and operating professional application software," the city council told the German Federation of Taxpayers. Running Linux will ultimately prove unsustainable, suggests the council, due to the need to also keep a minority of Windows machines to run line-of-business software incompatible with Linux. "In the long term, this situation means that the operation of the non-uniform client landscape can no longer be made cost-efficient"... Since completing the multi-year move to LiMux, a custom-version of the Linux-based OS Ubuntu, the city always kept a smaller number of Windows machines to run incompatible software. As of last year it had about 4,163 Windows-based PCs, compared to about 20,000 Linux-based PCs. The assessment is at odds with a wide-ranging review of the city's IT systems by Accenture last year, which found that most of the problems stem not from the use of open-source software, but from inefficiencies in how Munich co-ordinates the efforts of IT teams scattered throughout different departments. Dr. Florian Roth, leader of the Green Party at Munich City Council, said the review had also not recommended a wholesale shift to Windows. "The Accenture report suggested to run both systems because the complete 'rollback' to Windows and MS Office would mean a waste of experience, technology, work and money," he said... The city's administration is investigating how long it would take and how much it would cost to build a Windows 10 client for use by the city's employees. Once this work is complete, the council will vote again in November on whether this Windows client should replace LiMux across the authority from 2021. A taxpayer's federation post urged "Penguin, adieu!" -- while also admitting that returning to Windows "will devour further tax money in the millions," according to TechRepublic. "The federation's post also makes no mention of the licensing and other savings achieved by switching to LiMux, estimated to stand at about €10m."' -- source: https://linux.slashdot.org/story/17/10/15/2344244 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 Has Already Fixed the Wi-Fi Attack Vulnerability; Android Will Be Patched Within Weeks
by Peter Reutemann 16 Oct '17

16 Oct '17

'Microsoft says it has already fixed the problem for customers running supported versions of Windows. From a report: "We have released a security update to address this issue," says a Microsoft spokesperson in a statement to The Verge. "Customers who apply the update, or have automatic updates enabled, will be protected. We continue to encourage customers to turn on automatic updates to help ensure they are protected." Microsoft is planning to publish details of the update later today. While it looks like Android and Linux devices are affected by the worst part of the vulnerabilities, allowing attackers to manipulate websites, Google has promised a fix for affected devices "in the coming weeks." Google's own Pixel devices will be the first to receive fixes with security patch level of November 6, 2017, but most other handsets are still well behind even the latest updates. Security researchers claim 41 percent of Android devices are vulnerable to an "exceptionally devastating" variant of the Wi-Fi attack that involves manipulating traffic, and it will take time to patch older devices.' -- source: https://mobile.slashdot.org/story/17/10/16/166220 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/

Millions of High-Security Crypto Keys Crippled by Newly Discovered Flaw
by Peter Reutemann 16 Oct '17

16 Oct '17

'Slovak and Czech researchers have found a vulnerability that leaves government and corporate encryption cards vulnerable to hackers to impersonate key owners, inject malicious code into digitally signed software, and decrypt sensitive data, reports ArsTechnica. From the report: The weakness allows attackers to calculate the private portion of any vulnerable key using nothing more than the corresponding public portion. Hackers can then use the private key to impersonate key owners, decrypt sensitive data, sneak malicious code into digitally signed software, and bypass protections that prevent accessing or tampering with stolen PCs. The five-year-old flaw is also troubling because it's located in code that complies with two internationally recognized security certification standards that are binding on many governments, contractors, and companies around the world. The code library was developed by German chipmaker Infineon and has been generating weak keys since 2012 at the latest. The flaw is the one Estonia's government obliquely referred to last month when it warned that 750,000 digital IDs issued since 2014 were vulnerable to attack. Estonian officials said they were closing the ID card public key database to prevent abuse. On Monday, officials posted this update. Last week, Microsoft, Google, and Infineon all warned how the weakness can impair the protections built into TPM products that ironically enough are designed to give an additional measure of security to high-targeted individuals and organizations.' -- source: https://it.slashdot.org/story/17/10/16/1736252 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/

Nobel Prize Winner Argues Tech Companies Should Be Changing The World
by Peter Reutemann 16 Oct '17

16 Oct '17

'Tech companies are competing to serve the wealthy, argues the winner of the 2006 Nobel Peace Prize, complaining there's no "global vision," with big innovations instead "designed and dedicated mostly for commercial successes... while trillions of dollars are invested in developing robotics and artificial intelligence for military and commercial purposes, there is little interest in applying technology to overcome the massive human problems of the world." A genius in the tech industry "can dedicate his work to creating a medical breakthrough that will save thousands of lives -- or he can develop an app that will let people amuse themselves." As an exception, he cites the low-cost Endless computer, which runs Linux and has 50,000 Wikipedia articles pre-installed to enable offline research -- plus more than 100 applications -- for a price of just $79. "One part of Endless's business is operated like a conventional, profit-seeking company, while the other part is a social business that provides underserved populations with educational, health, and creative services they were once denied. Endless is already being shipped around the globe by four of the five largest computer manufacturers. It has become the leading PC platform in Indonesia and much of Southeast Asia. It has also been selected as the standard operating system for the Brazilian Ministry of Education, and in coming months it will be adopted as the primary platform by a number of other Latin American countries." The article is by Muhammad Yunus, who pioneered the concepts of microcredit and microfinance, and is taken from his new book, A World of Three Zeros: The New Economics of Zero Poverty, Zero Unemployment, and Zero Net Carbon Emission' -- source: https://news.slashdot.org/story/17/10/15/1739212 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/
