Is that a Samsung charging antenna in your pocket or ...

Wireless charging is fun, but the limited range and speed of induction charging makes it more of a gimmick than a useful tool for the moment.  Samsung is looking to resolve one of those limitations by using far field energy transfer; their current prototypes are able to reliably transfer power over 40cm but they intend far more.  The Register describes the major hurdle for transferring power this way, interference between the antennas because of motion or signal interference significantly reduces the efficiency of power transfer.  Take a look at how they propose to solve this issue as well as alternate suggestions from different researchers.

"An alternative approach is far-field energy transfer, which requires two antennas, one sending electromagnetic waves to the other. The receiving antenna then converts this radiation into electric currents."

The Premiere Mechanical Gaming Keyboard

Corsair has long been the company to beat in the world of RGB mechanical gaming keyboards. With the K95 RGB Platinum, they present their flagship: an oversize, fully-programmable, light show of a board with the kind of rapid response competitive gamers crave. But for $199, it’s a steep asking price. Is it worth such a high MSRP? Let’s find out.

The K95 RGB Platinum comes in nice packaging in the standard Corsair black and yellow. We have a nice profile shot of the keyboard on the front and the features highlighted on the back. It’s also one of the few cases where the marketing shots really undersell the keyboard. It looks much better in person, especially in low light.

Inside, the keyboard comes in a dust-preventative plastic sleeve with the wrist rest, ten replacement keycaps (QWER, ASDF, WD), and keycap puller under the keyboard itself.

Taking a closer look at the keyboard, the first thing that stands out is just how refined it is compared to the previous K95s or popular K70 variants. Compared to the K68 we looked at previously, the K95 is a massive upgrade, featuring a full aluminum top plate, aluminum volume roller, a glossy illuminated Corsair sails logo, and a dedicated control area for profile switching, brightness control, and Windows Lock. It also features a gorgeous LED light bar along the top rim, a USB 3.0 pass-through, and six programmable macro keys along the left side.

You've been diagnosed with terminal projected gradient descent

Subject: General Tech | April 20, 2018 - 01:10 PM |
Tagged: security, scary, health, PGD

Researchers have demonstrated how a projected gradient descent attack is able to fool medical imaging systems into seeing things which are not there.  A PGD attack degrades pixels in an image to convince an image recognition tool into falsely identifying the presence of something in an image, in this case medical scanners.  The researchers were successful in fooling three tests, a retina scan, an x-ray and a dermatological scan for cancerous moles; regardless of their access level on the scanner itself.  Take a look over at The Register for more information on this specific attack as well as the general vulnerability of image recognition software.

"Medical AI systems are particularly vulnerable to attacks and have been overlooked in security research, a new study suggests."

 Ryzen 2 is no longer on the horizon, it has crossed both the pinnacle and the ridge and now descends upon us.  Zen has matured and while it may not be conducting a waltz it is surely doing more than a simple two step as demonstrated by its deft ability to weave multiple threads.  Along with the increase in frequencies comes a welcome drop in prices as the flagship APU, with included prismatic spray cooler is barely over $300 or $400 depending on which side of the border you have chosen.  The Tech Report concurs with Ryan, AMD's construction phase wasn't so bad, but now that they have come to peace with their inner selves the Editors are Choosing them left, right and center.

AMD, tongue, cheek; check

AMD had a little fun yesterday as the head of Radeon Gaming, Scott Herkelman posted a comment about AMD's Radeon GPUs offering freedom of choice to gamers; unless they disapprove of the colour red of course.  FreeSync is certainly a good example of this commitment, offering non-proprietary adaptive sync technology to display manufacturers; on the other hand those who favour penguin flavoured operating systems might take exception to their statement.  Those shopping for GPUs in the near future should keep an eye out for new branding as the market seems to be poised for a bit of a change; either as a refresh of existing product lines or hopefully new products.  The Inquirer has opined about the comment in this post; though we have not yet heard from their articulate and unflappable CEO.

"While AMD doesn't mention Nvidia by name, it noted that proprietary tech from other hardware brands can stymie freedom of choice when it comes to selecting PC components and systems."

The simple life, Far Cry 5's graphics settings

Subject: General Tech | April 18, 2018 - 01:58 PM |
Tagged: gaming, far cry 5

The graphics options in the new Far Cry have gone back to simplicity, with Ultra settings turning on all available features, so you won't have to spend as much time hunting for settings and enabling them as you did in a few of the prior incarnations. You can choose between SMAA or TAA depending on your preference as neither showed any significant performance impact in [H]ard|OCP's testing.  If you are planning on playing in 4K, the GTX 1080 Ti is your best bet, though the non-Ti version and AMD's RX Vega 64 are capable of running this resolution on High settings.  At 1440p or lower you have a wide variety of choice as any of the cards tested could manage a decent experience, albeit not necessarily on Ultra. 

Check out the full performance review here.

"We test eleven GPU's performance from the low-end, to the top-end in Far Cry 5. Our goal is to find what settings are playable on each video card in Far Cry 5, and to compare the performance. We will also look at AA and Volumetric Fog performance. If you want to find what the best value GPU is for this game, this is for you."

Now there's a good sign, Ryzen 2 can almost hit 6GHz

Subject: General Tech | April 17, 2018 - 02:27 PM |
Tagged: ryzen 2, overclocking, LN2, amd

It took liquid nitrogen to do, but an experienced overclocker took the 4.3GHz Ryzen 7 2700X all the way to 5.884GHz and and the 4.2GHz Ryzen 5 2600X to 5.882GHz.  If that doesn't impress you, then how about the fact that all cores were running at that speed, and not just one core active?  You will not see such high frequencies when using less esoteric cooling solutions however this indicates some serious overclocking potential for the new Ryzens in general.  Check out the proof by following The Inquirer's links here.

"AMD'S RYZEN 2 processors are set to be proper powerhouses as the Ryzen 7 2700X and Ryzen 5 2600X chips have been overclocked beyond a preposterously nippy 5.8GHz."

Overview

Despite the recent launch of the high-powered Hades Canyon NUC, that doesn't mean the traditional NUC form-factor is dead, quite the opposite in fact. Intel continues to iterate on the core 4-in x 4-in NUC design, adding new features and updating to current Intel processor families.

Today, we are taking a look at one of the newest iterations of desktop NUC, the NUC7i7DNHE, also known as the Dawson Canyon platform.

Microsoft Takes a Mulligan with Windows 10 Build 17134

Subject: General Tech | April 16, 2018 - 09:21 PM |
Tagged: microsoft, windows 10

We were supposed to get Windows 10 build 17133 last week – but we didn’t.

windows-10-bandaid.png

As it turns out, Microsoft says that they noticed their reliability metrics fall below their comfortable threshold, so they pulled the build. They could have fixed the issues with a Cumulative Update, but they didn't. While I’m sure Microsoft doesn’t want you to avoid Windows Updates, cough cough, the feature updates are kind-of the blank slates that get updated, so it’s probably for the best that they meet a certain level of stability. I mean, it would suck to not be able to install an update because your machine crashes before it installs the update that fixes the crash, right?

Fast forward a week, though, and we now have a new build, 17134, which is being pushed to Insiders. This means that it will probably be a bit of time before the public gets their hands on it. It would seem kind-of odd to push a build to Insiders and then YOLO it to the world at large the very next day.

Maybe next week? Maybe the week after? No idea. It's coming, though.
