New submitter purnima writes: Australia keeps on giving and giving. Each year school kids in Australia sit The National Assessment Program (NAPLAN) which in part tests literacy. The exam includes a written page-long essay aimed at examining both language aptitude and literacy of students. Of course, human-marking of such essays is costly (twenty teacher-minutes per exam). So some bright spark has proposed that the essays be marked by computer. The government is convinced and the program is slated for the 2017 school year. Aside from the moral issues, is AI ready for this major task?

An anonymous reader writes: Y Combinator's Paul Graham has posted an essay arguing in favor of relaxed immigration rules. His argument is straight-forward: with only 5% of the world's population, the U.S. can only expect about 5% of great programmers to be born here. He says, "What the anti-immigration people don't understand is that there is a huge variation in ability between competent programmers and exceptional ones, and while you can train people to be competent, you can't train them to be exceptional. Exceptional programmers have an aptitude for and interest in programming that is not merely the product of training."

Graham says even a dramatic boost to the training of programmers within the U.S. can't hope to match the resources available elsewhere. "We have the potential to ensure that the U.S. remains a technology superpower just by letting in a few thousand great programmers a year. What a colossal mistake it would be to let that opportunity slip. It could easily be the defining mistake this generation of American politicians later become famous for."

HughPickens.com writes Highway driving, which is less complex than city driving, has proved easy enough for self-driving cars, but busy downtown streets—where cars and pedestrians jockey for space and behave in confusing and surprising ways—are more problematic. Now Will Knight reports that Michigan's Department of Transportation and 13 companies involved with developing automated driving technology are constructing a 30-acre, $6.5 million driverless town near Ann Arbor to test self-driving cars in an urban environment. Complex intersections, confusing lane markings, and busy construction crews will be used to gauge the aptitude of the latest automotive sensors and driving algorithms and mechanical pedestrians will even leap into the road from between parked cars so researchers can see if they trip up onboard safety systems. "I think it's a great idea," says John Leonard, a professor at MIT who led the development of a self-driving vehicle for a challenge run by DARPA in 2007. "It is important for us to try to collect statistically meaningful data about the performance of self-driving cars. Repeated operations—even in a small-scale environment—can yield valuable data sets for testing and evaluating new algorithms." The testing facility is part of broader work by the University of Michigan's Mobility Transformation Facility that will include putting up to 20,000 vehicles on southeastern Michigan roads. By 2021, Ann Arbor could become the first American city with a shared fleet of networked, driverless vehicles. "Ann Arbor will be seen as the leader in 21st century mobility," says Peter Sweatman, director of the U-M Transportation Research Institute. "We want to demonstrate fully driverless vehicles operating within the whole infrastructure of the city within an eight-year timeline and to show that these can be safe, effective and commercially successful."

Taco Cowboy writes with this story about new research that finds a strong genetic component to a child's ability in math and reading. "You may think you're better at reading than you are at math (or vice versa), but new research suggests you're probably equally good (or bad) at both. The reason: The genes that determine a person's ability to tackle one subject influence their aptitude at the other, accounting for about half of a person's overall ability. The study, published Tuesday in the journal Nature Communications, used nearly 1,500 pairs of 12-year-old twins to tease apart the effects of genetic inheritance and environmental variables on math and reading ability. The researchers administered a set of math and verbal tests to the children and then compared the performance of different sets of twins. They found that the twins' scores — no matter if they were high or low — were twice as similar among pairs of identical twins as among pairs of fraternal twins. The results indicated that approximately half of the children's math and reading ability stemmed from their genetic makeup.

A complementary analysis of unrelated kids corroborated this conclusion — strangers with equivalent academic abilities shared genetic similarities. What's more, the genes responsible for math and reading ability appear to be numerous and interconnected, not specifically targeted toward one set of skills. These so-called 'generalist genes' act in concert to determine a child's aptitude across multiple disciplines. The finding that one's propensities for math and reading go hand in hand may come as a surprise to many, but it shouldn't. People often feel that they possess skills in only one area simply because they perform slightly worse in the other."

DavidGilbert99 writes "James Dyson only releases products he is 100% happy with, which is why, despite nearly a decade of research in the area, his company has yet to release a robotic vacuum cleaner. To help drive research forward, he will invest £5 million in a joint research lab at Imperial College London which will focus on 'vision systems,' which Dyson hopes will help create the next generation of 'intelligent domestic robots.'" Last week Dyson proposed that the UK government offer monetary incentives to students with an interest and aptitude in science.

DavidGilbert99 writes "The inventor of the bagless vacuum cleaner believes there is an engineering crisis in the UK and that 61,000 vacancies in the area will go unfilled in 2014. To address this Dyson believes says he wants the UK government to offer monetary incentives to students with an interest and aptitude in science — as well as changing the current visa system to make it easier for foreign students to remain in the country and get work once they have completed their education in the UK."

necro81 writes "Lt. Gen. Mikhail T. Kalashnikov, an arms designer for the Soviet Union, creator of the AK-47, passed away today at age 94. Kalashnikov was born a peasant and entered the Soviet Army as a conscript. However, the self-taught tinkerer had an aptitude that took him far. The AK-47, his best-known creation, was praised for its reliability and low cost; attributes that have made it the most successful firearm ever, seeing use in homeland defense, rebellion, terrorism, and untold massacres. The inventor was himself ambivalent about the uses his creation had seen, but was nevertheless proud of his contribution to his country, where he is praised as a hero."

caferace writes "I've been around the block. I'm a long-time worker in the tech industry (nearly 30 years), absolutely kickass SQA and Hardware person, networking, you name it. But I'm 50+ now, and finding new regular or contract work is a pain. And it shouldn't be. I have the skills and the aptitude to absorb and adapt to any new situations and languages way beyond what any of my college age brethren might have. But when I send out a perfectly good resume and use the more obvious resources there are still precious few bites for someone requiring to work remotely. Am I just whining, or is this common? Are we being put out to pasture far too early?"

ananyo writes "He founded two genetic-sequencing companies and sold them for hundreds of millions of dollars. He helped to sequence the genomes of a Neanderthal man and James Watson, who co-discovered DNA's double helix. Now, entrepreneur Jonathan Rothberg has set his sights on another milestone: finding the genes that underlie mathematical genius. Rothberg and physicist Max Tegmark, who is based at the Massachusetts Institute of Technology in Cambridge, have enrolled about 400 mathematicians and theoretical physicists from top-ranked US universities in a study dubbed 'Project Einstein'. They plan to sequence the participants' genomes using the Ion Torrent machine that Rothberg developed. Critics say that the sizes of these studies are too small to yield meaningful results for such complex traits. But Rothberg is pushing ahead. 'I'm not at all concerned about the critics,' he says, adding that he does not think such rare genetic traits could be useful in selecting for smarter babies. Some mathematicians, however, argue that maths aptitude is not born so much as made. 'I feel that the notion of "talent" may be overrated,' says Michael Hutchings, a mathematician also at Berkeley."

HonorPoncaCityDotCom writes "The gift for spatial reasoning — the kind that may inspire an imaginative child to dismantle a clock or the family refrigerator — is sometimes referred to as the 'orphan ability' for its tendency to go undetected. Now Douglas Quenqua reports that according to a study published in the journal Psychological Science, spatial ability may be a greater predictor of future creativity or innovation than math or verbal skills, particularly in math, science and related fields. 'Evidence has been mounting over several decades that spatial ability gives us something that we don't capture with traditional measures (PDF) used in educational selection,' says David Lubinski, the lead author of the study and a psychologist at Vanderbilt. 'We could be losing some modern-day Edisons and Fords.' Spatial ability can be best defined as the ability to 'generate, retain, retrieve, and transform well-structured visual images.' Some examples of great inventors who have used their high levels of spatial ability to innovate include James Watt, who is known for improving the steam engine, and James Watson, co-discoverer of the structure of DNA. Nikola Tesla, who provided the basis for alternating current (AC) power systems, is said (or fabled) to have been able to visualize an entire working engine in his mind and be able to test each part over time to see what would break first. Testing spatial aptitude is not particularly difficult but is simply not part of standardized testing because it is considered a cognitive function — the realm of I.Q. and intelligence tests — and is not typically a skill taught in school. 'It's not like math or English, it's not part of an academic curriculum,' says Dr. David Geary. 'It's more of a basic competence. For that reason it just wasn't on people's minds when developing these tests.'"

GisG writes "General aptitude tests and specific mental ability tests are important tools for vocational guidance. Researchers are now asking whether performance on such tests is based on differences in brain structure, and if so, can brain scans be helpful in choosing a career? In a first step, researchers writing in the open access journal BMC Research Notes have investigated how well eight tests used in vocational guidance correlate to gray matter in areas throughout the brain." The researcher's (provisional) paper is available as a PDF.

kghapa writes "Still want to argue that video games shrink your brain? While video games have been previously shown to stimulate brain activity and improve coordination skills, a recently published study has directly linked structures in the human brain with video game aptitude. And yes, apparently size does matter in this case. Quoting: '... each subject received 20 hours of training to play a video game specifically created for research purposes, called Space Fortress. It's basically an Asteroids-type arcade game, in which the object is to knock down and destroy an enemy fortress while dodging space mines. However, the game has lots of extra twists that require close attention. Some of the players were told to focus exclusively on running up a high score, while others were told to shift their priorities between several goals. The result? The subjects who had more volume in an area called the nucleus accumbens did significantly better in the early stages of training. Meanwhile, those who were well-endowed in different areas of the striatum, known as the caudate nucleus and putamen, handled the shifting strategies better.'"

brothke writes "While there is a plethora of books such as Public Speaking for Dummies, and many similar titles, Confessions of a Public Speaker is unique in that it takes a holistic approach to the art and science of public speaking. The book doesn't just provide helpful hints, it attempts to make the speaker, and his associated presentation, compelling and necessary. Confessions is Scott Berkun's first-hand account of his many years of public speaking, teaching and television appearances. In the book, he shares his successes, failures, and many frustrating experiences, in the hope that the reader will be a better speaker for it." Keep reading for the rest of Ben's review.

An anonymous reader writes "I would like to know if there are any resources on the Web or elsewhere describing how to configure a Windows PC for an older parent not living in the same household. Assume little computer familiarity or aptitude. Some stuff is obvious, like using only a few large icons for favorite Web sites, or an icon perhaps for composing email and another for checking email. Other considerations are eliminating nuisance messages from Windows update and antivirus/firewall. What works and what doesn't? Can anyone who has worked/volunteered at a senior center offer some insights?"

bxwatso writes "My niece just took the ACT and got a perfect score on the math section. 25 years ago, when I took the test, the kids who aced the math section were pretty special. Her score, combined with straight A's so far in high school, suggest to me that she might be able to go to a top university (MIT?) based on her math aptitude. The rub is that she doesn't like math or science, even though she finds them easy. She doesn't want to be an engineer or scientist. I thought the folks here would be a great group to ask: What are some creative, not too nerdy professions that nonetheless require a talent for math, engineering, or science?"

GameSetWatch is running a piece discussing some of the ways in which gameplay can progress from simple to complex. The author talks about how acquiring items, new abilities, or just increasing the player's overall effectiveness can make it difficult for game designers to keep their content balanced and interesting. Quoting: "What do I mean by progression? There are at least two distinct types of progression in computer games, which I'll label player progression, and character progression (narrative progression is arguably a third). Player progression is the increasing aptitude of the player in mastering the game: whether through learning and understanding the technical rules of the game (surface play) or the implications of those rules (deep play). ... Character progression is the unlocking of additional rules of play, or altering the existing rules, by choices or actions within the game."

mlimber writes "The NYTimes has a story about how Congress has quietly begun to press for an equal number of women in the hard sciences and engineering under Title IX, which is best known for mandating numerical equality for boys' and girls' sports for institutions that accept federal funding. The problem is, the article says, it is not merely that women face discrimination from male colleagues, though that is often true, or that they are discouraged from pursuing these fields. Rather, women with aptitude in these areas often simply have other interests and so pursue their education and careers in other fields like law, education, or biology. Opponents of this plan, including many women in scientific fields, say implementing sex-based quotas will actually be detrimental because it will communicate that the women can't compete on even terms with men and will be 'devastating' to the quality of science 'if every male-dominated field has to be calibrated to women's level of interest.'"

r3lody writes "Finding a single book that encompasses what you want to learn can be difficult. Most cover a few portions of a subject in depth and skim over (or omit) others. Other books will cover each topic at about the same level: high enough to give an impression of what can be done, but not with enough depth to do it without a lot of effort. In A Practical Guide to Ubuntu Linux, Mark G. Sobell has created a single volume that gives the reader enough information to effectively install, configure and run workstations and servers using Ubuntu Linux. He has come the closest I have seen to containing all of the necessary information without being too shallow. Granted, to include everything you would want to know about Ubuntu Linux would take several books of this size, but this particular one provides most users the best bang for the buck. A DVD with the Gutsy Gibbon release of Ubuntu in a directly bootable form is included with the book." Read below for the rest of Ray's review.
