Having posted the referenced lengthy account of my GPU issues above I need to retreat the line of argument that it falls into the same issue category as my MBP and is not the by others faulted Early 2011 model.

My MacBook with the issues described is a:
Retina MacBook Pro Mid 2012 a.k.a.
MacBookPro10,1 Sales# MC975LL/A, Model# A1398, Production week 27-2012
with a discrete NVIDIA GT650M chip.

The issue of a lack of transparancy on HW issues I can nevertheless underline from having an issue-ridden MBP from another prior episode. The (first) Intel MBP 2006 I had in use produced a high pitch whining noise which similarly resulted in 2 mainboard swaps. The time it took until it became an acknowledged issue with service being aware of it was lengthy, and the customer experience then mimicked the one described before...

Submission + - Naps Nurture Growing Brains (sciencemag.org)

Submitted by sciencehabit on Tuesday September 24, 2013 @04:17PM

sciencehabit writes: Few features of child-rearing occupy as much parental brain space as sleep, and with it the timeless question: Is my child getting enough? Despite the craving among many parents for more sleep in their offspring (and, by extension, themselves), the purpose that sleep serves in young kids remains something of a mystery—especially when it comes to daytime naps. Do they help children retain information, as overnight sleep has been found to do in adults? A new study provides the first evidence that daytime sleep is in fact critical for effective learning in young children.

I was at an EU company which built a worldwide massive business based on what was in-house developed silicon - a chip - as crystallization point. The semiconductor capability was consecutively sold and innovations of a similar kind did not happen as far as I know thereafter.

Submission + - 200 Lumen/Watt Production Power LEDs Introduced (cree.com)

Submitted by ndverdo on Saturday December 29, 2012 @10:23PM

ndverdo writes: Cree just announced production power LEDs reaching 200 lumen/watt. Approximately doubling the previous peak LED light efficiency, the new LEDs will require less cooling. This should enable the MK-R series to finally provide direct no-hassle replacements to popular form-factors such as MR-16 spots and incandescent lighting in general. The LEDs are sampling and it is stated that "production quantities are available with standard lead times". Reaching a 1600 lm luminous flux light output these LEDs should bring a bright future indeed.

Submission + - Energy-Rich Cooked Food as Human Evolutionary Advantage (pnas.org)

Submitted by ndverdo on Monday October 22, 2012 @08:32PM

ndverdo writes: In a potentially significant discovery, Karina Fonseca-Azevedo and Suzana Herculano-Houzel of the Universidade Federal do Rio de Janeiro, Brasil report that ape brain development was constrained by the low calorie efficacy of uncooked food: in order to provide energy to a human-size brain they would have had to eat 2 hours more per day — running into a constraint as they already spend an "average maximal" of 8 hours per day eating.

The research has been published in the PNAS paper Metabolic constraint imposes tradeoff between body size and number of brain neurons in human evolution So will feeding apes cooked food from now on lead to a Planet of the Apes scenario?

The binary system Alpha Centauri is with 4.37 light years the closest stars to the sun. The planet's orbit is similar to Mars'. The planet was detected by a small periodic gravitational effect on its parent star.

choongiri writes: Canada's election fraud scandal continues to unfold. Elections Canada just matched the IP address used to set up thousands of voter suppression robocalls to one used by a Conservative Party operative, and a comparison of call records found a perfect match between the illegal calls, and records of non-supporters in the Conservative Party's CIMS voter tracking database, as well as evidence access logs may have been tampered with. Meanwhile, legal challenges to election results are underway in seven ridings, and an online petition calling for an independent public inquiry into the crisis has amassed over 44,000 signatures. The Conservative Party still maintains their innocence, calling it a baseless smear campaign.

Submission + - Diamonds Used To Increase Density, Performance of Phase-Change Memory (computerworld.com)

Submitted by Lucas123 on Friday May 04, 2012 @05:04PM

Lucas123 writes: Researchers at Johns Hopkins University have shown they can increase the density, performance and the durability of phase-change memory (PSM) by using diamonds to change the base alloy material. Instead of using the more typical method of applying heat to the alloy to change its state from amorphous to crystalline, thereby laying down bits in the material, the researchers used pressure from diamond-tipped tools. Using pressure versus heat allowed them to slow down the change in order to produce many varying states allowing more data to be stored on the alloy. "This phase-change memory is more stable than the material used in current flash drives. It works 100 times faster and is rewritable millions of times," said the study's lead author, Ming Xu, a doctoral student at the Whiting School of Engineering at Johns Hopkins University. "Within about five years, it could also be used to replace hard drives in computers and give them more memory."

Submission + - Nanoparticles heated by radio waves switch on genes in mice (nature.com)

Submitted by ananyo on Friday May 04, 2012 @10:29AM

ananyo writes: Researchers have used radio waves to remotely activate engineered insulin-producing genes in mice. In the long term, the work could lead to medical procedures in which patients’ genes are triggered on demand.
The researchers coated coated iron oxide nanoparticles with antibodies that bind to a modified version of a temperature-sensitive ion channel. They injected these particles into tumors grown under the skins of mice, then heated the nanoparticles with low-frequency radio waves. The nanoparticles heated the ion channel, activating it and allowing calcium to flow into cells. The influx of calcium switched on an engineered calcium-sensitive gene that produces insulin (abstract).

Despite those honorable intentions, the $35 ARM-based credit-card sized computer has captured the imagination of programmers, consumers and tinkerers alike, resulting in unprecedented demand for the product.

Last month the first 10,000 credit-card sized computers were set to make their way to those who pre-ordered them back in February. TechSpot takes a look at the Pi Model B, covering the basic steps for setting up the computer, as well as basic post-installation tasks those first using it might encounter.
