Inflating High School Graduation Statistics

Katherine Mangan observes that over ninety variants of the high school diploma exist, and many of these do not prepare students for university work. As the comments suggest, the desire to improve the high school graduation rate from 50% to 100% has resulted in the secondary education diploma being devalued, making a university degree the equivilent of the former high school diploma.

Increasing the Life of USB Drives

Stephen Lawson reports on efforts by SanDisk to increase the reliability and lifespan of flash memory used in USB drives and security devices such as cameras and sound monitors. The new drives are rated to work at temperatures as low as -40 C, compared with consumer devices that stop working below -25 C. The new drives will be able to accept as many as 128TB of information writes, far more than consumer grade drives.

The new capacity comes at the cost of slower writes and a current limit on total drive memory capacity of 64GB.

Affirmation Effect

Carmen Gallo shares two words that Joel Osteen says should preceed any personal self-affirmation. Unfortunately, Gallo's article is so brief that I cannot tell if what is espoused is positive thinking or something more scientifically or theologically based.

I commend to the reader Mitch Horowitz's book One Simple Idea: A Short History of Positive Thinking, which is available both in print or audio formats. Horowitz reviews the development and growing acceptance of positive thinking and the self affirmation movement in the United States.

My own belief is that the positive impact of self affirmation is limited by personal gifting and providence. My preference is the phrase used in "The Little Engine That Could."

Lesson Sharing Sites and Intellectual Property

Stephen Sawchuk reviews the legal rights teachers can surrender by posting to lesson-sharing sites . Sawchuk provides exerpts from various site licenses, some of which transfer the right of sale to hosting site.

Sawchuk notes that it is still unclear who ownes a teacher's lesson:

The 1909 [copyright] law establishing U.S. copyright policy made employers the owner of employee work products and carved out a special exemption for teachers. But in what some suspect might have been a drafting error, Congress deleted that exemption when it rewrote the law in 1976. (Section "Who Owns A Lesson?" para. 5)

To quote Sawchuk's conclusion: "In other words, dull and uninspiring though it is: Read the fine print."

Robots Helping Humans

Sharon Gaudin opins that robots will soon be our personal digital assistants . She quotes Defense researcher Pam Melroy, who is excited about the possibilities of bionic prostheses for wounded veterans:

The ability to control a robotic arm with just thoughts, with an RF signal and a chip in a woman's brain has already been demonstrated. It doesn't yet send signals back, but that will happen and it will close that loop. We are just not that far away from this ability to think things [and make a robot move]. It sounds like magic, but it's all about electrical brain signals.

The Value of Known Ignorance

Thor Olavsrud muses on the value of known ignorance , citing baseball analyst Bill James:

Speaking at the NetSuite NYSE Disruption Summit at the New York Stock Exchange on Friday, James and Beane both expressed that in business, as in baseball, the key to making the most of the data you're collecting is to let go of preconceptions and start thinking of areas of ignorance as mines of opportunity.

"Ignorance is inexhaustible and a vast resource to all of us," says James, now senior advisor on Baseball Operations for the Boston Red Sox, a far cry from his early days writing about baseball stats while working as a night-shift security guard at Stokely-Van Camp's pork and beans cannery. "Whenever you find something that you do not know, that you could know, that's gold. That's an opportunity to turn lead into gold."

"It's taking bucketfuls out of an ocean," he adds. "Every field is shot through with things that people are convinced are true but just aren't true. Areas of growth are based on discovering those things you know that just aren't true."

The trick is to look into that sea of the unknown and understand what is quantifiable and what isn't.

Google Search by Voice

Sharon Gaudin reports that Google is improving voice search . Gaudin paraphased Google Fellow Amit Singhai as saying "that future searches will be more like conversations with your computer or device, which also will be able to give you information before you even ask for it."

Gaudin notes that voice recognition inaccuracies have slowed adoption. She quotes consultant Patrick Moorhead as saying "Very few people rely on any smartphone voice products. They only will rely on them when the accuracy gets to 99%. Imagine if your keyboard only was accurate 95% of the time, meaning every five keys out of 100 were inaccurate. So this is a nice improvement, but until the complete user experience gets to 99% it won't really make a difference in adoption."
