Submission + - Nvidia RTX 40-series GPUs hampered by low quality thermal paste (pcgamer.com)
smooth wombat writes: Anyone who is into gaming knows your graphics card is under strain trying to display modern graphics. This results in increased power usage which is then turned into heat. Keeping your card cool is a must to get the best performance possible. However, hardware tester Igor's Lab found that vendors for Nvidia RTX 40-series cards are using cheap, poorly applied thermal paste which is leading to high temperatures and consequently performance degradation over time. This penny pinching has been confirmed by Nick Evanson at PC Gamer.
I have four RTX 40-series cards in my office (RTX 4080 Super, 4070 Ti, and two 4070s) and all of them have quite high hotspots—the highest temperature recorded by an individual thermal sensor in the die. In the case of the 4080 Super, it's around 11 C higher than the average temperature of the chip. I took it apart to apply some decent quality thermal paste and discovered a similar situation to that found by Igor's Lab.
In the space of a few months, the factory-applied paste had separated and spread out, leaving just an oily film behind, and a few patches of the thermal compound itself. I checked the other cards and found that they were all in a similar state.
Igor's Lab examined the thermal paste used on a brand-new RTX 4080 and found it to be quite thin in nature, due to large quantities of cheap silicone oil being used, along with zinc oxide filler. There was lots of ground aluminium oxide (the material that provides the actual thermal transfer) but it was quite coarse, leading to the paste separating quite easily.
Removing the factory-installed paste from another RTX 4080 graphics card, Igor's Lab applied a more appropriate amount of a high-quality paste and discovered that it lowered the hotspot temperature by nearly 30 C.

The clipper chip was a back-doored encryption device. It has nothing to do with the hardware level access that the ME has in an Intel based system.

"MINIX can still potentially change your computer's fundamental settings." Give me a break. MINIX provides nothing that enables this. It could have been WinCE or even raw ASM and had the same capability. Its all about the hardware! What a dumb statement.

I agree. It isn't a surprise that modern machine learning can recognize patterns. I don't see how this is even close to innovative. Now if it resulted in changing treatment offered to patients such that the outcomes were improved relative to current human Dr recommendations, then that would be interesting.
Submission + - Sony outage disables DASH devices, no ETA on a fix
Jack Greenbaum writes: In 2012 Sony closed the developer site for the DASH, their version of the Chumby platform. Sony never officially killed off the product, and they kept the back end servers on line, until recently at least. About two weeks ago DASH owners started seeing their devices fail with a cryptic error message "Unable to download the Control Panel (No download information available). Please restart your dash to try again." Sony acknowledges that the issue is at their end, but no ETA for a fix has been provided. The passionate DASH community is not pleased that Sony is being so quiet about a fix. One user even overslept for work because they depended on the alarm clock feature. Now every DASH is dead until Sony decides to not abandon its walled garden.

Submission + - 3D Windowing System Developed Using Wayland, Oculus Rift (phoronix.com)
An anonymous reader writes: Developed as part of a university master thesis is a "truly 3D" windowing system environment. The 3D desktop was developed as a Qt Wayland compositor and output to an Oculus Rift display and then controlled using a high-precision Razer mouse. Overall, it's interesting research for bringing 2D windows into a 3D workspace using Wayland and the Oculus Rift. The code is hosted as the Motorcar Compositor. A video demonstration is on YouTube.

Thanks to the net, almost anyone with a basic handle on chemistry can design, manufacture and sell their own narcotics, and in most cases the cops are utterly unable to stop them. This piece is kind of crazy: the writer actually creates a new powerful-but-legal stimulant based on a banned substance, and gets a Chinese lab to manufacture it.
