Microsoft Edge Accused of Sneakily Importing Firefox Data In Windows 10
by Peter Reutemann 24 Jun '20

24 Jun '20

'Some Firefox users have discovered that the new default Windows 10 browser, which is shipped to their devices via Windows Update, sometimes imports the data from Mozilla's application even if they don't give their permission. Softpedia reports: Some of these Firefox users decided to kill the initial setup process of Microsoft Edge, only to discover that despite the wizard shutting down prematurely, the browser still copied data stored by Mozilla's browser. Several users confirmed on reddit that this behavior happened on their computers too. Microsoft has remained tight-lipped on this, so for the time being, it's still not known why Edge imports Firefox data despite the initial wizard actually killed off manually by the user. Users who don't want to be offered the new Edge on Windows Update can turn to the dedicated toolkit that Microsoft released earlier this year, while removing the browser is possible by just uninstalling the update from the device.' -- source: https://news.slashdot.org/story/20/06/23/2027205 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/

80,000 Printers Are Exposing Their IPP Port Online
by Peter Reutemann 24 Jun '20

24 Jun '20

'In a report published earlier this month, security researchers from the Shadowserver Foundation, a non-profit organization focused on improving cyber-security practices across the world, have published a warning about companies that are leaving printers exposed online. More specifically, Shadowserver experts scanned all the four billion routable IPv4 addresses for printers that are exposing their IPP port. IPP stands for "Internet Printing Protocol" and, as the name suggests, is a protocol that allows users to manage internet-connected printers and send printing jobs to printers hosted online. The difference between IPP and the multiple other printer management protocols is that IPP is a secure protocol that supports advanced features such as access control lists, authentication, and encrypted communications. However, this doesn't mean that device owners are making use of any of these features. Shadowserver experts said they specifically scanned the internet for IPP-capable printers that were left exposed without being protected by a firewall and allowed attackers to query for local details via the "Get-Printer-Attributes" function. In total, experts said they usually found an average of around 80,000 printers exposing themselves online via the IPP port on a daily basis. The number is about an eighth of all IPP-capable printers currently connected online. A normal scan with the BinaryEdge search engine reveals a daily count of between 650,000 and 700,000 devices with their IPP port (TCP/631) reachable via the internet. What are the issues with not securing the IPP port? Shadowserver experts say this port can be used for intelligence gathering, since many of the printers scanned returned additional info about themselves, such as printer names, locations, models, firmware, organization names, and even Wi-Fi network names. "To configure IPP access control and IPP authentication features, users are advised to check their printers' manuals," adds ZDNet. "Most printers have an IPP configuration section in their administration panel from where users can enable authentication, encryption, and limit access to the device via access lists."' -- source: https://hardware.slashdot.org/story/20/06/23/2049236 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-Based Japanese Supercomputer is Now the Fastest in the World
by Peter Reutemann 24 Jun '20

24 Jun '20

'A Japanese supercomputer has taken the top spot in the biannual Top500 supercomputer speed ranking. Fugaku, a computer in Kobe co-developed by Riken and Fujitsu, makes use of Fujitsu's 48-core A64FX system-on-chip. It's the first time a computer based on ARM processors has topped the list. From a report: Fugaku turned in a Top500 HPL result of 415.5 petaflops, 2.8 times as fast as IBM's Summit, the nearest competitor. Fugaku also attained top spots in other rankings that test computers on different workloads, including Graph 500, HPL-AI, and HPCG. No previous supercomputer has ever led all four rankings at once. While fastest supercomputer rankings normally bounce between American- and Chinese-made systems, this is Japan's first system to rank first on the Top500 in nine years since Fugaku's predecessor, Riken's K computer. Overall there are 226 Chinese supercomputers on the list, 114 from America, and 30 from Japan. US-based systems contribute the most aggregate performance with 644 petaflops' -- source: https://tech.slashdot.org/story/20/06/23/1614232 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/

Windows 10 Linux Subsystem: You Get GPU Acceleration -- With Intel, AMD, Nvidia Drivers
by Peter Reutemann 23 Jun '20

23 Jun '20

'Nvidia, Intel and AMD have announced their support for Microsoft's new effort to bring graphics processor support to the Windows 10 Windows Subsystem for Linux to enhance machine-learning training. From a report: GPU support for WSL arrived on Wednesday in the Dev Channel preview of Windows 10 build 20150 under Microsoft's reorganized testing structure, which lets it test Windows 10 builds that aren't tied to a specific future feature release. Microsoft announced upcoming GPU support for WSL a few weeks ago at Build 2020, along with support for running Linux GUI apps. The move on GPU access for WSL is intended to bring the performance of applications running in WSL2 up to par with those running on Windows. GPU compute support is the feature most requested by WSL users, according to Microsoft. The 20150 update includes support for Nvidia's CUDA parallel computing platform and GPUs, as well as GPUs from AMD and Intel. It also supports DirectML (Direct Machine Learning), Microsoft's Windows 10 API for hardware-accelerated machine learning.

Google To Start Fact-Checking Google Images
by Peter Reutemann 23 Jun '20

23 Jun '20

'In an effort to curb the spread of misinformation on its platform, Google said Monday it would begin to fact-check Google Images search results. From a report: The danger of text-based misinformation could be dwarfed by that posed by misleading, manipulated and outright fake photos and videos, including convincing "deepfakes" generated with the aid of artificial intelligence. The move, a first among major search engines, comes as tech firms continue to wrestle with how to address the misinformation that continue to run rampant on their platforms. Beginning Monday, Google will surface fact-check information in Google Images around the world, a similar effort to what is does in its regular search and news results.' -- source: https://tech.slashdot.org/story/20/06/22/1634217 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/

Nvidia Engineer Releases Open-Sourced Vulkan Graphics Driver for the Raspberry Pi
by Peter Reutemann 22 Jun '20

22 Jun '20

'Earlier this year, the Raspberry Pi Foundation hooked up with Igalia to start development on an open-sourced Vulkan graphics driver for the Raspberry Pi. However, Martin Thomas, an engineer at Nvidia, beat them to the punch. Thomas announced yesterday via his personal Twitter that his RPi-VK-Driver is ready for primetime. The talented engineer had been working on the Vulkan driver in his spare time for more than two years. Technically, Thomas' iteration isn't a Vulkan driver per se because it doesn't comply with the official standards established by The Khronos Group. Nonetheless, the resourceful developer produced a driver that adheres to the Vulkan parameters as much as possible, and as close as the hardware would permit it. There's just one limitation with the RPi-VK-Driver though. Unlike the official Vulkan driver that's still in the works, Thomas' version is only compatible with the Broadcom VideoCore IV GPU that's found inside the Raspberry Pi 1, 2, 3 and Zero devices.' -- source: https://tech.slashdot.org/story/20/06/21/185227 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/

Anyone Can Build This Open Source, DRM-Free Kindle Alternative
by Peter Reutemann 21 Jun '20

21 Jun '20

'It’s harder to get an open source e-reader than you might think. Kindles are popular, but they lock you into Amazon’s ecosystem. Amazon’s books come with digital rights protection and the company can remove them from your device whenever it wants. Those problems exist on tablets from Barnes and Nobles, Google, and Apple, too. When it comes to open source reading, there’s just no good options. The Open Book Project wants to change that. As first spotted by Hackster.io, “the Open Book aims to be a simple device that anyone with a soldering iron can build for themselves,” designer Joey Castillo said on the GitHub repository for the project. Castillo is still prototyping the device, and his goal is to build an e-reader that anyone can redesign, recode, or accessorize as they see fit. Of course, it should be able to read books in any format, from ePub to MOBI and everything in between. Castillo’s prototype is built from a circuit board of his own design. The design works in the Adafruit Feather ecosystem, a user friendly set of development boards and electronics. Castillo has listed all the parts you’ll need to build your own open source e-reader and tweak the design on his GitHub. (Castillo is still working on the device’s firmware, so you’ll have to write it yourself or wait for a release.)' -- source: https://www.vice.com/en_us/article/7x5kpb/anyone-can-build-this-open-source… 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/

AI Magic Comes At A Price
by Lawrence D'Oliveiro 20 Jun '20

20 Jun '20

Interview with a software developer <https://www.theregister.com/2020/06/19/generative_adversarial_networks_are_…> about the pitfalls of using Generative Adversarial Networks (GANs) for the specific task of adding colour to old monochrome images. You can get them to produce good results most of the time, then every now and then they will go wrong in some weird and unsettling way: "GANs would spit out very weird specific glitches like odd splashes of colour on someone's hand and it made them look creepy," he told us. In some examples, people have turned an eerie alien green. And trying to tweak things manually can just as easily make things worse as better. He offers an open-source version of his product here <https://github.com/jantic/DeOldify>. Note the Jupyter notebooks. ;)

Lawsuit vs. Western Digital wants to end any use of SMR in NAS drives
by Peter Reutemann 19 Jun '20

19 Jun '20

'Law firm Hattis & Lukacs has filed an amendment to its class-action lawsuit against Western Digital for including SMR technology in its WD Red line of NAS drives. The amendment adds five more named plaintiffs from five new states, and it includes significant additional technical detail. If you aren't up to date on the SMR saga, this is one article in an ongoing series. The short version: SMR—Shingled Magnetic Recording—is a relatively new hard drive recording technology that allows higher data densities. It does so by laying down overlapping tracks—like shingles on a roof—with a write head that's wider than the read head. Unfortunately, this technology makes rewriting existing disk sectors agonizingly slow in many cases—rewriting a single 4KiB sector will generally mean needing to both read and rewrite an entire 256MiB zone. The original American class-action suit (there's a Canadian one as well) had a single named plaintiff, Wisconsin's Nicholas Malone. The amendment features five new plaintiffs, each from a different state, and tells each plaintiff's story in detail. New York plaintiff Steve Gravel's story is particularly wince-inducing—he wasn't just using the drives for photo and movie storage; he had an iSCSI target on his QNAP NAS, and the performance decrease when he replaced CMR drives with SMR was, as you might expect, terrible.' -- source: https://arstechnica.com/information-technology/2020/06/lawsuit-vs-western-d… 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/
