Free Stanford Online Class on Computer Networks

Stanford University announces "Free Public Online Class: An Introduction to Computer Networks".

From the e-mail description by Professor Nick McKeown:
Professor Philip Levis and I are teaching one of these free (and often massive) public online classes this Autumn quarter as an "Introduction to Computer Networks". The material is designed to be broadly accessible to anyone who wants to understand the design principles of computer networks, with a special emphasis on how the Internet works. The class is based on our CS144 class for Stanford juniors and seniors, which will run in parallel.
The class begins October 8, 2012.

Human Support Robot

"Toyota has unveiled a new assistant robot designed to help the disabled live more independently."
Called the Human Support Robot (HSR), it represents the latest initiative in Toyota's Partner Robot program and is intended to help out around the home by fetching things, opening curtains, and picking up objects that have fallen to the floor.

Can a Robot Pass the University of Tokyo Math Entrance Exam?

"Can a robot pass the University of Tokyo math entrance exam?"

From the article:
The test uses high-school math problems. For a computer to solve a math problem, it needs three things, according to NII:
  1. Semantic analysis: Understand the problem text, which is expressed as natural language and formulas easily understood by humans.
  2. Formulation: Convert to a form that can be processed by a computer.
  3. Calculation: Find the answer using the mathematical solver.
So far, Todai Robot can solve about 50–60% of Todai’s Level 2 entrance-exam problems, Fujitsu says.

Gorilla Glass

"Gorilla Glass is the thin strong glass used for the screens of most smartphones. It was invented in the 1960s by Corning but was shelved in the early 1970s due to a lack of demand. The iPhone brought it out of retirement in a big way."

Most And Least Common Four-Digit PINs

An analysis of 3.4 million four-digit PINs.

Some tidbits:
The most popular password is 1234 -- nearly 11%
The next most popular 4-digit PIN in use is 1111 with over 6% of passwords being this.
In third place is 0000 with almost 2%. 
Hence, "a staggering 26.83% of all passwords could be guessed by attempting these 20 combinations!"

The least popular 4-digit password was 8068.  Many more interesting bits of data in the full article.

Sniffing Out Malignancies

Faster, please: "A Technion scientist has developed a breath test to determine whether a growth is benign or malignant":
Breath tests are usually used to test for drunkenness, or perhaps halitosis. But Dr. Hossam Haick of the Technion has found a new use for breath tests – determining whether or not a growth in the lung is benign, or malignant...

War On Men?

"Women Are Paying Huge Sums To Have a Daughter Rather Than a Son"

Some interesting excerpts:
The conventional wisdom has always been this: Given a choice, couples would prefer sons. That has certainly been the case in places like China and India, where couples have used pregnancy screening to abort female fetuses. But in the United States, a different kind of sex selection is taking place: Mothers like Simpson are using expensive reproductive procedures so they can select girls...

For Jennifer Merrill Thompson, the reasons were simple. “I’m not into sports. I’m not into violent games. I’m not into a lot of things boys represent and boys do,” she said. Thompson is the author of Chasing the Gender Dream, a self-published book that documents her use of gender-selection technology to conceive her daughter.
Interviews with several women from the forums at in-gender.com and genderdreaming.com yielded the same stories: a yearning for female bonding. Relationships with their own mothers that defined what kind of mother they wanted to be to a daughter. A desire to engage in stereotypical female activities that they thought would be impossible with a baby boy.
 I guess gender stereotyping is ok if it's done by affluent American women.
