This looks like a Big One (or many) for those lost in Windows:


It's 2017... And Windows PCs can be pwned via DNS, webpages, Office docs, fonts – and some TPM keys are fscked too

Microsoft today released patches for more than 60 CVE-listed vulnerabilities in its software...

Among the latest holes that need papering over via Windows Update are three vulnerabilities already publicly disclosed – with one being exploited right now by hackers to infect vulnerable machines...

PS: Etienne Stalmans and Saif El-Sherei of SensePost say they've been able to achieve "command execution on Microsoft Word without any macros, or memory corruption," using the DDE protocol. We're told Microsoft, for now, considers it a feature, and not a bug.

[...]

No surprise, that exposed DDE 'feature not a bug' is already actively out in the wild for yet more malware to exploit Windows users:

Watch out for Microsoft Word DDE nasties...

... good ol' Office malware has biz workers in its sights again...

... It's the latest in a series of cyber-attacks leveraging DDE, which seems to be popular again with malware developers. Microsoft still supports [the feature and hence the vulnerability], so expect to see more of this kind of attack...

Indeed, the 'Windows Fall Creators Update' has hit:


Windows Fall Creators Update is here: What do you want first – bad news or good news?

... Microsoft’s efforts in making in-place upgrade smooth have paid off. There will always be cases where things go wrong, but the speed and reliability of the in-place upgrade is generally good...

... Another key upgrade is that the Windows Subsystem for Linux (WSL) is now fully released...

... The Windows team continues its efforts to bring more settings to the [their one and only,] modern user interface, but this remains frustrating...

... Who runs your Windows 10 installation, you the user, or Microsoft? ... especially since its purpose is opaque. “I don’t like things being downloaded without my permission,” says the top review...

... Windows 10 today is too noisy, not least because of Microsoft’s official apps nagging you for feedback or store reviews...

... Should you install Fall Creators? If you run Windows 10, absolutely yes. It is worth it, if only for Files on Demand and the finished Linux subsystem...

... This article nicely explains the latest "QLC" announcement and gives an idea of how the 'QLC' works:

Toshiba Showcases QLC NAND Development Platform At Flash Memory Summit

Last month Toshiba announced QLC (4-bit per cell) storage using BiCS 3 technology. We've heard about QLC for around a year now but never expected to see it this soon. At Flash Memory Summit we not only saw QLC, but also saw it running in a development platform...


Note how the "L" in "QLC" is something of a misnomer. The "L" could describe a "level-4" ('quad') development. However, the "L" is very definitely NOT what would be commonly assumed to be for describing merely 4 levels of voltage when in reality you must have at least 16 levels of charge to encode 4 bits of data...

Here's a good follow-up with pretty diagrams that nicely explain the structure, compromises and endurance for examples of QLC flash:

Facebook Asks For QLC NAND, Toshiba Answers with 100TB QLC SSDs With TSV

... 100TB QLC SSDs. Toshiba plans to pioneer the use of QLC (Quad-Level Cell) technology with a new variant of its 64-layer BiCS3 NAND, but the company will also employ its TSV (Through-Silicon Via) technology to boost its die stacking capability, which effectively doubles capacity per package. QLC NAND makes several tradeoffs, particularly [with] endurance and performance ... but it will provide more density...


With only a dozen or so electrons to kick around at a time (for SLC/MLC planar NAND), spectacular and scary stuff for your data! Phew!!

Keep searchin',
Martin

SLC: 'Single'-Level Cell, two levels of charge (voltage) storing 1 bit of data;
MLC: 'Multiple'-Level Cell, four levels of charge (voltage) storing 2 bits of data.

Eh, a Pascal BIOS edit? Or an edit of how BOINC reads the hardware is more like it.


The later one is correct. BOINC reads hardware and replaces the 1080 Ti with 1080 Tu and multiplies the count by four.
When issuing tasks to GPUs it calculates bitwise (n & 3) to get GPU number 0-3. It runs one task at a time per GPU.

Tu stands for Tuesday for obvious reasons.

Just one awesome consequence of having so many PCIe channels available as part of the standard package for AMD Ryzen:


AMD ThreadRipper NVMe RAID Released

... Now, all of the pieces are available to users. We haven't researched every single motherboard, but a quick look at select products all listed updated BIOS files. The AMD RAIDXper2 RAID Management Utility and NVMe RAID Driver for Windows was also published by AMD in the support section.

AMD chose to give the feature away as a value-add rather than charge customers, as Intel plans to do with the X299 platform. Even though X299 documentation refers to VROC and dongles needed to fully support the feature, Intel has yet to release the dongles.



Wow! Function/feature restricting super-expensive and irksome DONGLES are so user-gouging restrictive old fashioned!! How can Intel Marketing ever imagine that old trick can still work?!

AMD is a very clear winner on that score for extreme performance, and also some very worthwhile everyday performance, all as standard, immediately available.

Not so sure on the "trounced"... There's always the game of choosing your benchmarks. Intel is still expensively 'king' for old-style single threaded tasks. Then again, you don't bother about multi-core if you are so passionate about old-years-out-of-date single threads! (I thought we'd moved on since last century!! :-P )

There's some good apt comments for that vid. For just one:

Cempaka261 (Silly vulgar ending...)
i dont know how they think people will choose 7980XE over the 1950X? twice the price and just few % better performance? it cost twice!!! my i7 6700k is my last cpu from these money grabbing...

I know it would have made more sense to compare Epyc vs Dual Xeon, but the OP asked about TR. I question why you would want to spend $1000 on a TR 1950X when you can buy the Epyc 7401P for $1100 which gets you 24cores/48 threads.

All a question of which motherboard and which form factor you prefer?...


Unfortunately, there also seems to be an obfuscating irrational game of Marketing and Hype to bamboozle the Marketing junkies!

AMD continues to champion the push for us all to escape the far-too-long long 'single supplier' stagnation:


AMD Ryzen Threadripper 1950X Game Mode, Benchmarked

If you crave lots of cores and tons of PCIe connectivity, like most content creators, multitaskers, and software developers, then Threadripper is for you. It might also be a good fit if you're a gamer who simultaneously runs heavily threaded productivity applications in the background.

The Zeppelin die really is a feat of modern engineering. However, its architecture is dissimilar from anything that came before, creating issues in some software written prior to Ryzen's introduction. AMD worked with game developers to iron out the performance wrinkles we identified at launch, and we've seen big speed-ups in a number of titles as a result. But expanding beyond Ryzen 7, 5, and 3 into a dual-die configuration adds a new set of challenges for Threadripper.

AMD's fix involves two toggles that affect how the processor operates, giving you modes optimized for whatever workload you're running...



Retail AMD Threadripper Delidded, Four Die Present

... Earlier this year, Der8auer delidded a Threadripper engineering sample and found that the processors still feature all four Zeppelin die, similar to AMD's EPYC data center processors. AMD uses only two die for the Threadripper models, so many speculated that it might be possible to unlock the other dies and their extra cores...


Custom Core i9 De-Lidder - To Delid At Any Price

Several generations ago, Intel stopped using solder between the die and the IHS for all of its processors. That doesn't help average users, and it certainly penalizes overclockers...


Forum Post Claims Z390 Chipset, Intel 8-Core CPUs Coming To Market Next Year

... Whether or not the claimed eight-core models would utilize Intel's 10nm process ... is an open question. Cramming in two more cores with Coffee Lake is quite the feat with 14nm technology, be it 14nm+ or 14nm++, but doubling core counts with the same process is unlikely due to thermal and power constraints. That implies the eight-core processors will feature Ice Lake's 10nm+ process, but the leaked roadmap specifically refers to the Z390 chipset for "Coffee Lake-S" processors.

Intel's 8th Generation lineup includes the 14nm+ Kaby Lake-R (refresh), 14nm++ Coffee Lake, and 10nm Cannon Lake processors, which might explain the need for another new chipset. Intel's disclosures indicate the company is moving forward with a new rollout strategy as the competition intensifies...



AMD Transitioning To 12nm LP Process For Vega, Ryzen In 2018

At the Global Foundries Technology Conference, AMD’s CTO Mark Papermaster announced that the company will be transitioning “graphics and client products” from the Global Foundries 14nm LPP FinFET process it uses today to the new 12nm LP process in 2018. Global Foundries also announced that 12LP will begin production in 1Q18...

... Samsung/Global Foundries and TSMC have closed the gap a little once they adopted the FinFET structure for their transistors. AMD's relatively quick transition to the 12nm LP processor is vital for the company as it seeks to compete with Intel's Coffee Lake processors and Nvidia's Volta GPUs...




Good to see the pace of developments ramp up.

But will the one big heavyweight player spoil the party again?...

A small ruse of patents to poison us all for a long time?...


Why did we use leaded petrol for so long?

Leaded petrol was safe. Its inventor was sure of it.

Facing sceptical reporters at a press conference in October 1924, Thomas Midgley dramatically produced a container of tetraethyl lead - the additive in question - and washed his hands in it.

"I'm not taking any chance whatever," Midgley declared...

... 'The loony gas building'

None of this surprised workers elsewhere in Standard Oil's facility. They knew there was a problem with tetraethyl lead.

As Gerald Markowitz and David Rosner note in their book Deceit and Denial: The Deadly Politics of Industrial Pollution, the lab where it was developed was known as "the loony gas building". Nor should it have shocked Standard Oil, General Motors or the DuPont Corporation, the three companies involved with adding tetraethyl lead to gasoline...

About a century ago, when General Motors had first proposed adding lead to petrol - in order to improve performance - scientists were alarmed. They urged the government to investigate the public health implications. Midgley breezily assured the surgeon general that "the average street will probably be so free from lead that it will be impossible to detect it or its absorption", although he conceded that "no actual experimental data has been taken"...

... Hamilton knew that lead had been poisoning people for thousands of years. In 1678, workers who made lead white - a pigment for paint - were described as suffering ailments including "dizziness in the head, with continuous great pain in the brows, blindness, stupidity". The Romans used lead in water pipes. Lead miners often ended up mad or dead...

Ethyl alcohol had much the same effect and wouldn't mess with your head, unless you drank it. Midgley knew this, having combined petrol with practically every imaginable substance, from iodine to camphor to melted butter.

Why did the petrol companies push tetraethyl lead instead of ethyl alcohol? Researchers who have studied the decision remain puzzled. Cynics might point out that any old farmer could distil ethyl alcohol from grain. It couldn't be patented, or its distribution profitably controlled. Tetraethyl lead could...

Children's brains are especially susceptible to chronic lead poisoning. Is it possible that kids who didn't breathe leaded petrol fumes grew up to commit less violent crime?...





Very nasty stuff that has poisoned us all for the sake of 'profits'.

And more recently, we have such as Monsanto using "Genetic Modifications" to patent 'novel' foods...

What could possibly go wrong again?


All in our only one world,
Martin
