Submission + - The 10 Commandments for New Linux Users (linuxbraindump.org) 2

An anonymous reader writes: Thou shalt not log in as root. Use "sudo" or "su -" for administrative tasks. That's how it starts. The rest are at Linux Brain Dump. How does the Slashdot community feel about these commandments? Should new users adhere to these guidelines? Do you have other suggestions?

Submission + - AJAX-Solutions For Professional Coding: Reviewed (smashingmagazine.com)

Vitaly Friedman writes: Web-developers can create amazing web-applications with AJAX. Netvibes, GMail and dozens of further web-projects offer a new level of interactivity we've used to give up the idea of. Modern web-applications can be designed with enhanced user interfaces and functionalities, which used to be the privelege of professional desktop-applications. AJAX makes it possible to create more interactive, more responsive and more flexible web-solutions. The article 80+ AJAX-Solutions For Professional Coding presents over 90 useful AJAX-based techniques. Auto-completion, instant field editing, menus, calendars, interactive elements, visual effects, animation, basic javascripts, as well as an extensive develope's suite.

Submission + - Someone Might Be Trying to Hack My Accounts

aplusjimages writes: I think I have someone trying to hack into my forum accounts that I have throughout the Internets. I've had 2 different forums email me that my account has been temporarily locked because someone has been trying, but failed to login to my account. Both forums have given me the IP Address 70.86.138.114. My question is what should I do about this? Both protection wise and possible retaliation wise. Thanks.

Submission + - Flaws in ARM and XScale (and likely PowerPC)

V4Vendetta writes: Barnaby Jack developed a method for exploiting certain NULL pointer dereferences on the ARM and XScale architectures (and likely PowerPC).

In general, NULL pointer dereference flaws are considered non-exploitable. On the XScale and ARM architectures the memory address 0 is mapped, and also holds the exception vector table. The exception vector table is a set of branch instructions that correspond to different exceptions, such as software and hardware interrupts. When a case arises that writes to the 0 address with user-defined source data, it is possible to gain execution control by rewriting the exception table.

This method affects a lot of devices since most mobile phones and PDA are ARM based (iPhone?), and high-end routers often use the XScale architecture. The PowerPC architecture (used by Nintendo Wii, XBox360 and Playstation 3) also stores the vector table at a low address, and is likely vulnerable to this same attack.

This attack is more reliable than a remote stack overflow, due to the fact that no offsets are required. You will always be writing to address 0. The only data needed by an attacker is a copy of the vector table, which can be acquired by downloading and reversing the targets firmware. As embedded exploitation is still in its infancy, I don't foresee a worm in the very near future — but yes, if a worm was targeting embedded devices, this would be a reliable attack vector.

Submission + - Five Things Every Software Developer Should Know (saperlaw.com)

BBrown writes: Saper Law Offices, the same Chicago law firm that has been mentioned here twice before for their successes against the RIAA, has posted a blog article on the legal issues surrounding software development. The article, titled "Five Things Every Software Developer Should Know", gives a concise but informative legal tutorial on patents, trademarks, and trade secrets. Definitely a must-read for anybody involved in a small or personal business doing software development.

Submission + - Father of scientific climatology says "hooey&#

An anonymous reader writes: "Reid Bryson, known as the father of scientific climatology, considers global warming a bunch of hooey.

The UW-Madison professor emeritus, who stands against the scientific consensus on this issue, is referred to as a global warming skeptic. But he is not skeptical that global warming exists, he is just doubtful that humans are the cause of it."

Bryson didn't see Al Gore's movie about global warming, "An Inconvenient Truth."

"Don't make me throw up," he said. "It is not science. It is not true."

Submission + - Is cash no longer legal tender? (uic.edu)

An anonymous reader writes: I attend the University of Illinois at Chicago. Last semester my housing arrangements went smoothly. I put down my application fee, and my deposit just fine, got a room for the semester and life went on. This semester, because there was supposedly a large number of students who did not check into their rooms last semester, we were required to make a $100 prepayment, in addition to the application fee and deposit. No problem, I think, I see the university is trying to make a quick buck off people who don't follow through with their plans. Now I do NOT have a checking account, a credit card, or anything. I am one of the few people who do EVERYTHING in cash. I don't trust the banks, I don't trust credit card companies. I also had a trip planned for out of the country, so I get my cash, and on my way to the airport, I stop by the housing office to make my prepayment. They refuse to take cash. They will not charge my university account (so I can pay the bursar or whoever I need to) in cash, and they want a check or money order. Nowhere in their letter did they say that. I fear out of technicality I am going to loose my housing since I cannot get them their money on time because they do not take cash. Is it legal for a state-owned university, let alone any business to not take legal tender?

Feed Hormone That Signals Fullness Also Curbs Fast Food Consumption And Tendency To B (sciencedaily.com)

The synthetic form of a hormone previously found to produce a feeling of fullness when eating and reduce body weight, also may help curb binge eating and the desire to eat high-fat foods and sweets. The findings on fast food consumption and binge eating tendencies are based on a six-week research study of 88 obese individuals.

Feed New Interview Technique Could Help Police Spot Deception (sciencedaily.com)

Shifting uncomfortably in your seat? Stumbling over your words? Can't hold your questioner's gaze? Police interviewing strategies place great emphasis on such visual and speech-related cues, although new research casts doubt on their effectiveness. However, the discovery that placing additional mental stress on interviewees could help police identify deception has attracted interest from investigators in the UK and abroad.

Feed Eurocom kicks out a quad-core laptop, the Phantom D900C (engadget.com)

Filed under: Laptops

We've definitely seen some shady reports of a quad-core laptop make the rounds, and it looks like geographically misnamed Canadian laptop outfit Eurocom is going to be first off the line with a Intel Core 2 Quad notebook. A Eurocom spokesperson apparently confirmed to Laptoping that the company is prepping a quad-core Phantom D900C -- which probably means that monster-laptop Clevo (or whichever company is their ODM) is working on a quad-core D900C, since the Phantom is yet another rebrand. Laptoping says the 17-inch machine will feature a 2.4GHz Q6600 "Kentsfield" Core 2 Quad and dual SLI-capable GeForce Go 8700 or Quadro FX3500 graphics, an HD DVD drive, and up to three drives that can be run as a RAID 0/1/5 array -- all of which means battery life on this 11.9-pound monster will probably run down faster than a 6-minute mile. Still, the idea of stuffing four cores into a laptop gets us all excited, but the current $3,200 pricetag on the dual-core Phantom doesn't bode too well for the double the power.
