Comment Tutor's Perspective (Score 1) 1268

As a high school math tutor for one of the large national test prep companies, I can say with complete certainty that even when the "box" is replaced with a variable name, students still do this. I find that it's not so much that they don't grasp that the = symbol means equality as much as that they don't realize what equality means.

If I give a problem like:

f(x) = 2x + 7
g(x) = sqrt( f(x) )*5

Many students can solve this problem; a good portion of them just understand "oh, I do a substitution" - they don't understand fully that the equality of a variable with some expression is WHY their answer is correct. Similarly, something like: 3/15 = x/225 Most students get thsi right; "oh, I just cross-multiply" - but they don't understand WHY cross-multiplication is the correct thing to do. Teachers need to start teaching real math in addition to problem solving methods and heuristics.

I would say "I guess I had it coming" if I chose my zip code as my password or made all of my "security questions" have answers that people could glean from a phonebook (or my facebook page).

I'm not trying to say that what he did was right. It was highly amusing, but terribly wrong, unethical and illegal. However, I think there should be a legal distinction between the willful hacking of computer systems (via intentional backdoors, security holes, malware, viruses/worms or password dictionary attacks) and guessing someone's password correctly, as there is a potential for huge differences in intent (which is relevant to most crimes in our legal system).

Even with murder, if you plan your crime in advance and take steps to put your plan into action, the crime is considered more severe than if you were to suddenly decide to kill someone as a "crime of passion." I'd argue that a similar distinction can be made between intentional electronic vandalism/espionage and casual password-guessing.

Bacteria Found Alive In Ice 120,000 Years Old 326

FiReaNGeL notes research presented this morning at Penn State on the discovery of a new, ultra-small species of bacteria that has survived for more than 120,000 years within the ice of a Greenland glacier at a depth of nearly two miles. From the psu.edu announcement: "The microorganism's ability to persist in this low-temperature, high-pressure, reduced-oxygen, and nutrient-poor habitat makes it particularly useful for studying how life, in general, can survive in a variety of extreme environments on Earth and possibly elsewhere in the solar system. This new species is among the ubiquitous, yet mysterious, ultra-small bacteria, which are so tiny that they are able to pass through microbiological filters. Called Chryseobacterium greenlandensis, the species is related genetically to certain bacteria found in fish, marine mud, and the roots of some plants."

Building a Miniature Magnetic Earth 150

Doofus writes "There was an interesting story on NPR this morning about a geophysicist who has constructed a miniature earth to model the earth's dynamo effects. Dan Lathrop, a geophysicist at the University of Maryland, has constructed a 10-foot diameter stainless steel sphere. He intends to fill the sphere with molten sodium and spin the sphere to examine the propensity for the system to generate its own magnetic field. The article includes both video, in which Lathrop spins up the sphere, and audio, including the conversion of magnetic wave functions in prior experiments into audible sound: literally the music of the spheres."

Gaze Gaming Tech Promises Faster Eye-Controlled Interaction 141

NewScientist is reporting that further research is progressing on new types of user input devices. Specifically, "gaze gaming," a technology that promises faster interaction using only your eyes. Currently technology for sight-based interaction is far too slow for practical applications in things like gaming. "Eye-gaze systems bounce infrared light from LEDs at the bottom of a computer monitor and track a person's eye movements using stereo infrared cameras. This setup can calculate where on a screen the user is looking with an accuracy of about 5 mm."

Second Person 184

Aeonite writes "As we all learned in English class, there are three points of view one can employ when writing: first person ("I learned"), second person ("You learned"), and third person ("He learned"). You are about to read a review of Second Person: Role-Playing and Story in Games and Playable Media, a book that addresses the use of second-person narration in games and related media. You are also likely to be eaten by a Grue." Read below for the rest of Michael's review.

US Court Orders Company to Use Negative Keywords 177

A US court has ordered a firm to utilize negative adwords in their internet advertising. "Orion Bancorp took Orion Residential Finance (ORF) to court in Florida over ORF's use of the word 'Orion' in relation to financial services and products, arguing that it had used the term since 2002 and had held a trade mark for it since then. [...] The judge in the case went further, though, restraining ORF from 'purchasing or using any form of advertising including keywords or "adwords" in internet advertising containing any mark incorporating Plaintiff's Mark, or any confusingly similar mark, and shall, when purchasing internet advertising using keywords, adwords or the like, require the activation of the term "Orion" as negative keywords or negative adwords in any internet advertising purchased or used.'"

Linux Desktop Distro Shootout 383

An anonymous reader writes "InfoWeek has posted an open-source OS comparison. Linux Shootout: 7 Desktop Distros Compared pits openSUSE, Ubuntu 8.4, PCLinuxOS, Mandriva Linux One, Fedora, SimplyMEPIS, and CentOS 5.1 against each other. And the winner is ... Ubuntu. Author Serdar Yegulalp writes: 'Ubuntu 8.4 remains one of the best desktop distributions for many good reasons: it works with almost any hardware you throw at it, and has tons of features for both existing Linux users and prospective converts from Windows.' He also gave openSUSE points for ease of use on the desktop, and Mandriva kudos for ease of administration."

How Water Forms in Interstellar Space at 10K 270

KentuckyFC writes "Water is the most abundant solid material in space. But although astronomers see it on planets, moons, in comets and in interstellar clouds, nobody has been able to show how it forms. In theory, it should form easily when oxygen and atomic hydrogen meet. The problem is that there is not enough of it floating around as gas in interstellar dust clouds. So instead, the thinking is that water must form when atomic hydrogen interacts with frozen solid oxygen on the surface of dust grains in these clouds. Now Japanese astronomers have demonstrated this process for the first time in the lab in conditions that simulate interstellar space. That's cool because all the water in the solar system, including almost every drop you drink on Earth today, must have formed in exactly this way more than 5 billion years ago in a pre-solar dustcloud (abstract)."
