Dell and HP Advise All Their Customers To Not Install Spectre BIOS Updates
by Peter Reutemann 25 Jan '18

25 Jan '18

'The Spectre and Meltdown mess continues with Dell now recommending their customers to not install the BIOS updates that are supposed to resolve the Spectre (Variant 2) vulnerabilities. These updates have been causing numerous problems for users including performance issues, boot issues, reboot issues, and general system stability. Due to this, Dell EMC has updated its knowledgebase article with a statement advising customers to not install the BIOS update and to potentially rollback to the previous BIOS if their computers are exhibiting "unpredictable system behavior". ZDNet reports that HP too has issued a similar advisory. The computer manufacturer pulled its softpaqs BIOS updates with Intel's patches from its website, and said it would be releasing a BIOS update with a previous version of Intel's microcode on Thursday.' -- source: https://tech.slashdot.org/story/18/01/24/1312241 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 Death Of Moore’s Law
by Lawrence D'Oliveiro 24 Jan '18

24 Jan '18

From <http://www.theregister.co.uk/2018/01/24/death_notice_for_moores_law/>: The computer science behind microprocessor design has therefore found itself making a rapid U-turn as it learns that its optimisation techniques can be weaponised. ... Hammered by the finance of physics and the weaponisation of optimisation, Moore’s Law has hit the wall, bounced off - and reversed direction. We’re driving backwards now: all things IT will become slower, harder and more expensive. Actually economics probably had more to do with it than physics, as PC sales have been slowing over the past decade.

City of Barcelona Dumps Windows For Linux and Open Source Software
by Peter Reutemann 24 Jan '18

24 Jan '18

'The City of Barcelona is migrating its computer systems away from the Windows platform, reports the Spanish newspaper El País. The City's strategy is first to replace all user applications with open-source alternatives, until the underlying Windows operating system is the only proprietary software remaining. In a final step, the operating system will be replaced with Linux... According to Francesca Bria, the Commissioner of Technology and Digital Innovation at the City Council, the transition will be completed before the current administration's mandate ends in spring 2019. For starters, the Outlook mail client and Exchange Server will be replaced with Open-Xchange. In a similar fashion, Internet Explorer and Office will be replaced with Firefox and LibreOffice, respectively. The Linux distribution eventually used will probably be Ubuntu, since the City of Barcelona is already running 1,000 Ubuntu-based desktops as part of a pilot... Barcelona is the first municipality to have joined the European campaign 'Public Money, Public Code'. This campaign is an initiative of the Free Software Foundation Europe (FSFE) and revolves around an open letter advocating that publicly funded software should be free. Currently, this call to public agencies is supported by more than 100 organisations and almost 15,000 individuals. With the new open-source strategy, Barcelona's City Council aims to avoid spending large amounts of money on licence-based software and to reduce its dependence on proprietary suppliers through contracts that in some cases have been closed for decades.' -- source: https://linux.slashdot.org/story/18/01/15/0415219 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 58 Gets Graphics Speed Boost, Web App Abilities
by Peter Reutemann 23 Jan '18

23 Jan '18

'Mozilla released on Tuesday a new version of its Firefox Quantum browser, boosting its graphics speed and improving a couple of new technologies designed to make the web more powerful. From a report: The browser, version 58, is the first major update since Mozilla's recovery plan hit full stride in November with the debut of Firefox Quantum. Speed is of the essence in Mozilla's recovery plan, and Firefox 58 does better than its predecessor in some graphics tasks by splitting work better across the multiple processor cores that computer chips have these days. The result should be scrolling that's smooth, uninterrupted by the stuttering that in computing circles goes by the disparaging term "jank." [...] Firefox 58 helps with two new web technologies. One, called WebAssembly, provides for dramatically faster web apps. Firefox 58 can get WebAssembly software running faster so you don't have to twiddle your thumbs waiting as long after clicking a link. Another is progressive web apps (PWAs), an initiative that came out of Google to help make the web a better match for the apps we all drop on our phones.' -- source: https://tech.slashdot.org/story/18/01/23/150206 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/

Fake Ads Redirecting To Malicious Software Installers
by Lawrence D'Oliveiro 23 Jan '18

23 Jan '18

Seems a consortium of fake ad companies has been built up, cultivating relationships with legitimate ad platforms, and then carefully inserting forced redirects in a proportion of the ads they serve, to trick unwitting viewers into installing malware on their machines. Various checks are first applied, to try to ensure that the machines being redirected don’t happen to be run by security researchers, for example. Each member of the consortium is activated for serving this malware in turn; then when it is exposed, it is abandoned and the operators move on to the next one. <https://arstechnica.com/information-technology/2018/01/malvertising-factory…>

Linux 4.15 Becomes Slowest Release Since 2011
by Peter Reutemann 23 Jan '18

23 Jan '18

'Linus Torvalds has decided that Linux 4.15 needs a ninth release candidate, making it the first kernel release to need that much work since 2011. Torvalds flagged up the possibility of an extra release candidate last week, with the caveat that "it obviously requires this upcoming week to not come with any huge surprises" after "all the Meltdown and Spectre hoopla" made his job rather more complicated in recent weeks. Fast-forward another week and Torvalds has announced "I really really wanted to just release 4.15 today, but things haven't calmed down enough for me to feel comfy about it."' -- source: https://tech.slashdot.org/story/18/01/22/2035228 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/

Ex-NSA Hacker Runs Christmas Lights With Raspberry πs And Dodgy NZ-Made Radio Kit
by Lawrence D'Oliveiro 22 Jan '18

22 Jan '18

<http://www.theregister.co.uk/2018/01/22/rob_joyce_hacking/>: Joyce uses a couple of Raspberry Pis to control the light show and a slightly dodgy FM transmitter to broadcast the soundtrack to visiting folks. The transmitter, bought as a kit from New Zealand, has the capability to broadcast illegally on FM frequencies, so is sold without the power supply attached to get around regulations, but Joyce said he keeps it low power and within FCC regulations because "I'm very legal."

Has the Decades-Old Floating Point Error Problem Been Solved?
by Peter Reutemann 22 Jan '18

22 Jan '18

'Wednesday a company called Bounded Floating Point announced a "breakthrough patent in processor design, which allows representation of real numbers accurate to the last digit for the first time in computer history. This bounded floating point system is a game changer for the computing industry, particularly for computationally intensive functions such as weather prediction, GPS, and autonomous vehicles," said the inventor, Alan Jorgensen, PhD. "By using this system, it is possible to guarantee that the display of floating point values is accurate to plus or minus one in the last digit..." The innovative bounded floating point system computes two limits (or bounds) that contain the represented real number. These bounds are carried through successive calculations. When the calculated result is no longer sufficiently accurate the result is so marked, as are all further calculations made using that value. It is fail-safe and performs in real time. Jorgensen is described as a cyber bounty hunter and part time instructor at the University of Nevada, Las Vegas teaching computer science to non-computer science students. In November he received US Patent number 9,817,662 -- "Apparatus for calculating and retaining a bound on error during floating point operations and methods thereof." But in a followup, HPCwire reports: After this article was published, a number of readers raised concerns about the originality of Jorgensen's techniques, noting the existence of prior art going back years. Specifically, there is precedent in John Gustafson's work on unums and interval arithmetic both at Sun and in his 2015 book, The End of Error, which was published 19 months before Jorgensen's patent application was filed. We regret the omission of this information from the original article.' -- source: https://science.slashdot.org/story/18/01/21/0157230 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 Fuchsia OS on the Pixelbook: It works! It actually works!
by Peter Reutemann 21 Jan '18

21 Jan '18

'Google currently has two OSes on the market: Android and Chrome OS. The company is never one to leave a successful product alone in the marketplace, though, so it's also developing a third operating system called "Fuchsia." When we last checked in on the experimental OS in May 2017, calling it an "OS" was a bit of a stretch. We only got the system UI up and running on top of Android, where it then functioned like an app. The UI offered a neat multi-window system, but mostly it was just a bunch of placeholder graphics. Nothing worked. It has been hard to check in on Fuchsia since. The Fuchsia system UI, which was written with a cross-platform SDK called "Flutter," quickly shut down the Android (and iOS) compatible builds. Fuchsia has a Vulkan-based graphics stack, and no emulator supports the new-ish graphics API. The only way to get Fuchsia up and running again was with actual hardware, and the only supported devices were Intel NUC PCs from 2015 and the Acer Switch Alpha 12 laptop. So after the recent news that the Fuchsia team picked the Chrome OS-powered Google Pixelbook as a supported device, we jumped at the chance to get it up and running. And after a little elbow grease, it actually booted. Now, we're not just running the system UI on top of Android like last time, we're running Fuchsia directly on a piece of hardware! This means it's finally time for a deep dive on what Fuchsia looks like in early 2018. Our usual in-development OS testing caveats apply: Fuchsia only started development in 2016 and probably has several years of development time ahead of it. Everything can—and probably will—change between now and release (if a release ever even happens). Google won't even officially acknowledge the OS exists—Fuchsia is a bunch of code sitting on fuchsia.googlesource.com.' -- source: https://arstechnica.com/gadgets/2018/01/googles-fuchsia-os-on-the-pixelbook… 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/
