Manjaro Linux Discontinues 32-bit Support
by Peter Reutemann 26 Sep '17

26 Sep '17

'Recently, Philip, the lead developer of Manjaro Linux, announced that the project would be dropping support for the 32-bit architecture. He said that the reason for the move was “due to the decreasing popularity of i686 among the developers and the community”. While Manjaro 17.0.3 is the last release to have a 32-bit ISO, current 32-bit installs will receive a short window of continued support. During September and October, 32-bit package will continue to be updated. However, starting in November, packages will be limited to 64-bit. After that period, 32-bit installs of Manjaro will essentially be unsupported.' -- source: https://itsfoss.com/manjaro-drops-32-bit-support/ 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/

Krita 3.3 Digital Painting App Promises Better HiDPI Support on Linux & Windows
by Peter Reutemann 26 Sep '17

26 Sep '17

'In the release announcement, Krita devs reveal the fact that they were forced to bump the version number from 3.2.x to 3.3.x because the upcoming Krita 3.3 release will be introducing some important changes for Windows platforms, such as support for the Windows 8 event API, thus supporting the n-trig pen in Surface laptops. "Alvin Wong has implemented support for the Windows 8 event API, which means that Krita now supports the n-trig pen in the Surface line of laptops (and similar laptops from Dell, HP and Acer) natively. This is still very new, so you have to enable this in the tablet settings," said the devs.' -- source: http://news.softpedia.com/news/krita-3-3-digital-painting-app-promises-bett… 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/

Clear Linux Project Announces the Next Generation of Intel's Clear Containers
by Peter Reutemann 26 Sep '17

26 Sep '17

Since I mentioned Clear Linux at last night's meeting... 'Rewritten in the Go language, Intel Clear Containers 3.0 introduces support for leveraging code used for namespace-based containers and better integrates into the container ecosystem, allowing support for Docker container engine and Kubernetes. It also improves the compatibility with the POSIX family of standards. "Today’s release presents a generational and architectural shift to utilize virtcontainers, a modular and hypervisor agnostic library for hardware virtualized containers. Clear Containers 3.0 is written in Go language and boasts an OCI compatible runtime implementation (cc-runtime) that works both on top of virtcontainers, and as a platform for deployment," said Amy L Leeland, Technical Program Manager, Intel Corporation. Additionally, this release ships with a new agent based on the libcontainer library that has been designed from the offset to let users apply filters and policies, such as the well-known SELinux and seccomp security facilities found in the Linux kernel, inside the Clear Containers guests.' -- source: http://news.softpedia.com/news/clear-linux-project-announces-the-next-gener… 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/

Tiny PocketBeagle is the RPi Zero of the BeagleBone world
by Peter Reutemann 25 Sep '17

25 Sep '17

'BeagleBoard.org’s tiny $25 PocketBeagle is a BeagleBone SBC clone, based on Octavo’s OSD3358-SM SiP module and offering micro-USB, microSD, and 72 I/O pins. BeagleBoard.org has released its smallest BeagleBone variant yet. The COM-like, 56 x 35 x 5mm PocketBeagle is a USB key-fob SBC built on the Octavo Systems OSD335x-SM System-In-Package (SiP) module that was announced earlier this week. Octavo’s 21 x 21mm SiP module, which packs a 1GHz Texas Instruments Sitara AM3358 SoC and nearly all the functions of a BeagleBone Black SBC into a BGA form factor, is 40 percent smaller than the original 27 x 27mm OSD335x.' -- source: http://linuxgizmos.com/tiny-pocketbeagle-is-the-rpi-zero-of-the-beaglebone-… 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/

Richard Stallman vs. Canonical's CEO: 'Will Microsoft Love Linux to Death?'
by Peter Reutemann 25 Sep '17

25 Sep '17

' TechRepublic got different answers about Microsoft's new enthusiasm for Linux from Canonical's founder and CEO Mark Shuttleworth, and from Richard Stallman. Stallman "believes that Microsoft's decision to build a Windows Subsystem for Linux (WSL) amounts to an attempt to extinguish software that users are free to run, copy, distribute, study, change and improve." "It certainly looks that way. But it won't be so easy to extinguish us, because our reasons for using and advancing free software are not limited to practical convenience," he said. "We want freedom. As a way to use computers in freedom, Windows is a non-starter..." Stallman remains adamant that the WSL can only help entrench the dominance of proprietary software like Windows, and undermine the use of free software. "That doesn't advance the cause of free software, not one bit," he says... "The aim of the free software movement is to free users from freedom-denying proprietary programs and systems, such as Windows. Making a non-free system, such Windows or MacOS or iOS or ChromeOS or Android, more convenient is a step backward in the campaign for freedom..." For Shuttleworth, Windows' embrace of GNU/Linux is a net positive for open-source software as a whole. "It's not like Microsoft is stealing our toys, it's more that we're sharing them with Microsoft in order to give everyone the best possible experience," he says. "WSL provides users who are well versed in the Windows environment with greater choice and flexibility, while also opening up a whole new potential user base for the open source platform..." Today Shuttleworth takes Microsoft's newfound enthusiasm for GNU/Linux at face value, and says the company has a different ethos to that of the 1990s, a fresh perspective that benefits Microsoft as much as it does open-source software. "Microsoft is a different company now, with a much more balanced view of open and competitive platforms on multiple fronts," he says. "They do a tremendous amount of engineering specifically to accommodate open platforms like Ubuntu on Azure and Hyper-V, and this work is being done in that spirit." The article also points out that Microsoft "does seem to be laying the groundwork for WSL to extend what's possible using a single GNU/Linux distro today, for instance, letting the user chain together commands from different GNU/Linux distros with those from Windows."' -- source: https://linux.slashdot.org/story/17/09/24/2132218 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/

ARM TrustZone Hacked By Abusing Power Management
by Peter Reutemann 24 Sep '17

24 Sep '17

'Many CPUs these days have DVFS (Dynamic Voltage and Frequency Scaling), which allows the CPU's clockspeed and voltage to vary dynamically depending on whether the CPU is idling or not. By turning the voltage up and down with one thread, researchers were able to flip bits in another thread. By flipping bits when the second thread was verifying the TrustZone key, the researchers were granted permission. If number 'A' is a product of two large prime numbers, you can flip a few bits in 'A' to get a number that is a product of many smaller numbers, and more easily factorable. "As the first work to show the security ramifications of energy management mechanisms," the researchers reported at Usenix, "we urge the community to re-examine these security-oblivious designs."' -- source: https://hardware.slashdot.org/story/17/09/23/2113243 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 CCleaner Malware Fiasco Targeted at Least 20 Specific Tech Firms
by Peter Reutemann 21 Sep '17

21 Sep '17

'Hundreds of thousands of computers getting penetrated by a corrupted version of an ultra-common piece of security software was never going to end well. But now it's becoming clear exactly how bad the results of the recent CCleaner malware outbreak may be. Researchers now believe that the hackers behind it were bent not only on mass infections, but on targeted espionage that tried to gain access to the networks of at least 20 tech firms. Earlier this week, security firms Morphisec and Cisco revealed that CCleaner, a piece of security software distributed by Czech company Avast, had been hijacked by hackers and loaded with a backdoor that evaded the company's security checks. It wound up installed on more than 700,000 computers. On Wednesday, researchers at Cisco's Talos security division revealed that they've now analyzed the hackers' "command-and-control" server to which those malicious versions of CCleaner connected. On that server, they found evidence that the hackers had attempted to filter their collection of backdoored victim machines to find computers inside the networks of 20 tech firms, including Intel, Google, Microsoft, Akamai, Samsung, Sony, VMware, HTC, Linksys, D-Link and Cisco itself. In about half of those cases, says Talos research manager Craig Williams, the hackers successfully found a machine they'd compromised within the company's network, and used their backdoor to infect it with another piece of malware intended to serve as a deeper foothold, one that Cisco now believes was likely intended for industrial espionage.' -- source: https://it.slashdot.org/story/17/09/21/1350214 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/

Security Researchers Warn that Third-Party GO Keyboard App is Spying on Millions of Android Users
by Peter Reutemann 21 Sep '17

21 Sep '17

'Security researchers from Adguard have issued a warning that the popular GO Keyboard app is spying on users. Produced by Chinese developers GOMO Dev Team, GO Keyboard was found to be transmitting personal information about users back to remote servers, as well as "using a prohibited technique to download dangerous executable code." Adguard made the discovery while conducting research into the traffic consumption and unwanted behavior of various Android keyboards. The AdGuard for Android app makes it possible to see exactly what traffic an app is generating, and it showed that GO Keyboard was making worrying connections, making use of trackers, and sharing personal information. Adguard notes that there are two versions of the keyboard in Google Play which it claims have more than 200 million users in tot' -- source: https://it.slashdot.org/story/17/09/21/1959218 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/

Firefox For iOS Gets Tracking Protection, Firefox Focus For Android Gets Tabs
by Peter Reutemann 21 Sep '17

21 Sep '17

'Mozilla today released Firefox 9.0 for iOS and updated Firefox Focus for Android. The iOS browser is getting tracking protection, improved sync, and iOS 11 compatibility. The Android privacy browser is getting tabs. You can download the former from Apple's App Store and the latter from Google Play. This is the first time Firefox has offered tracking protection on iOS, and Nick Nguyen, vice president of product at Mozilla, notes that it's finally possible "thanks to changes by Apple to enable the option for 3rd party browsers." This essentially means iPhone and iPad users with Firefox and iOS 11 will have automatic ad and content blocking in Private Browsing mode, and the option to turn it on in regular browsing. This is the same feature that's available in Firefox for Android, Windows, Mac, and Linux, as well as the same ad blocking technology used in Firefox Focus for Android and iOS' -- source: https://news.slashdot.org/story/17/09/21/1953205 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/
