+ - 173 Mind Maps: The Poor Man's Design Tool->

Submitted by
CowboyRobot
CowboyRobot writes ""UML too complex? Flowcharts too old school? Mind maps offer a simple way to capture designs and weave them together elegantly." The quickest way to begin designing a program is to simply write down the steps in normal text, but this method breaks down with more complex projects. UML can be a useful format for larger projects but can be difficult to get right, epecially when trying to use it with a less conventional project. The middle ground are 'Mind Maps', "a diagrammatic representation of loosely connected ideas. They are a central tool in brainstorming sessions. Mind map tools help capture ideas and then mush them around until you have the structure you want.""

An anonymous reader writes "Many iPhone 5 users are complaining that its camera is adding a purple flare to their photos. Speculation is that it's caused by the new sapphire lens cover that Apple touted as "thinner and more durable than standard glass with the ability to provide crystal clear images." Apple's response to those who've complained? "You're using it wrong.""

phr4nck (2743915) writes "I am in charge of a small website security. Everyday the FW logs show the IP address of people trying to get access to the system. This morning, I routinely was checking the file and a class A IP address trying to get root access held me up. It was coming from a big well known college on the US east coast. I contacted the IT security person and his first answer was:
"What are the timestamps on your logs? We located the machine a few hours ago and it should no longer be on our network."
I replied in sending a time stamped log file for which I received this answer:
"This host has been taken offline.
Thanks for reporting it."
It is not the first time I am reporting abusing access to my network and I have no idea if things are then taken seriously. What really to do? What would you do?
By the way the host is really currently offline."

hessian writes "Curiosity's onboard weather station, which is called the Remote Environment Monitoring Station (REMS), has measured air temperatures as high as 43 degrees Fahrenheit (6 degrees Celsius) in the afternoon. And temperatures have climbed above freezing during more than half of the Martian days, or sols, since REMS was turned on, scientists said.

These measurements are a bit unexpected, since it's still late winter at Gale Crater, the spot 4.5 degrees south of the Martian equator where Curiosity touched down on Aug. 5.

"That we are seeing temperatures this warm already during the day is a surprise and very interesting," Felipe Gómez, of the Centro de Astrobiología in Madrid, said in a statement."

Submitted by

CWmike writes "Microsoft co-founder Paul Allen has called Windows 8 'puzzling' and 'confusing initially,' but assured users that they would eventually learn to like the new OS. Allen, who co-founded Microsoft with Bill Gates in 1975, left the company in 1983 after being diagnosed with Hodgkin's disease. In a post to his personal blog on Tuesday — strangely titled in the third person as, 'Paul's take on Windows 8,' Allen said he has been running Windows 8 Release Preview — the public sneak peak Microsoft shipped May 31 — on both a traditional desktop as well as on a Samsung 700T tablet, designed for Windows 7. 'I did encounter some puzzling aspects of Windows 8,' Allen wrote, and said the dual, and dueling user interfaces (UIs), were confusing. 'The bimodal user experience can introduce confusion, especially when two versions of the same application — such as Internet Explorer — can be opened and run simultaneously,' Allen said."

Submitted by Anonymous Coward
An anonymous reader writes "National Institute of Standards and Technology (NIST) has just announced the winner of the SHA-3 competition: Keccak, created by Guido Bertoni, Joan Daemen and Gilles Van Assche of STMicroelectronics and Michaël Peeters of NXP Semiconductors.

“Keccak has the added advantage of not being vulnerable in the same ways SHA-2 might be,” says NIST computer security expert Tim Polk. “An attack that could work on SHA-2 most likely would not work on Keccak because the two algorithms are designed so differently.”

For Joan Daemen it must be a "two in a row" feeling, since he also is one of the authors of AES."

SchrodingerZ writes "With the price of gold skyrocketing in today's market, Michigan State University researchers have discovered a bacterium that can withstand high toxicity levels that are necessary to create natural gold. ''Microbial alchemy is what we're doing — transforming gold from something that has no value into a solid, precious metal that's valuable,' said Kazem Kashefi, assistant professor of microbiology and molecular genetics.' The bacteria is Cupriavidus metallidurans ; which is conditioned to be tolerant to heavy, toxic metals and be 25 times strong than most bacteria. When put into Gold-chloride (a natural forming toxic liquid), the bacteria reproduces and converts the liquid into a gold nugget. The complete process takes about a week to preform. This experiment is currently on tour as an art exhibit called 'The Great Work of the Metal Lover .'"

Submitted by
pigrabbitbear
pigrabbitbear writes "Created by four New York University students, Diaspora tried to destroy the notion that one network could completely dominate the web. Diaspora – "the privacy aware, personally controlled, do-it-all distributed open source social network,” as described on their Kickstarter page – offered what seemed like the perfect antidote to Zuckerbergian tyranny. The New York Times quickly got wind. Tired of being bullied, technologists rallied behind the burgeoning startup spectacle, transforming what began as a fun project into a political movement. Before a single line of code had been written, Diaspora was a sensation. Its anti establishment rallying cry and garage hacker ethos earned it kudos from across an Internet eager for signs of life among a generation grown addicted to status updates.

And yet, the battle may have been lost before it even began. Beyond the difficulty of actually executing a project of this scope and magnitude, the team of four young kids with little real-world programming experience found themselves crushed under the weight of expectation. Even before they had tried to produce an actual product, bloggers, technologists and open-source geeks everywhere were already looking to them to save the world from tyranny and oppression. Not surprisingly, the first release, on September 15, 2010 was a public disaster, mainly for its bugs and security holes. Former fans mockingly dismissed it as “swiss cheese.”"

Submitted by
ananyo
ananyo writes "One of the largest-ever studies of retractions has found that two-thirds of retracted life-sciences papers were stricken from the scientific record because of misconduct such as fraud or suspected fraud — and that journals sometimes soft-pedal the reason. The study contradicts the conventional view that most retractions of papers in scientific journals are triggered by unintentional errors.
The survey examined all 2,047 articles in the PubMed database that had been marked as retracted by 3 May this year. But rather than taking journals’ retraction notices at face value, as previous analyses have done, the study used secondary sources to pin down the reasons for retraction if the notices were incomplete or vague. he analysis revealed that fraud or suspected fraud was responsible for 43% of the retractions. Other types of misconduct — duplicate publication and plagiarism — accounted for 14% and 10% of retractions, respectively. Only 21% of the papers were retracted because of error (abstract)."

+ - 240 Graphics Cards: The Future of Online Authentication?->

Submitted by Gunkerty Jeb
Gunkerty Jeb (1950964) writes "Researchers working on the "physically unclonable functions found in standard PC components (PUFFIN) project" announced last week that widely used graphics processors could be the next step in online authentication. The project seeks to find uniquely identifiable characteristics of hardware in common computers, mobile devices, laptops and consumer electronics.

The researchers realized that apparently identical graphics processors are actually different in subtle, unforgeable ways. A piece of software developed by the researchers is capable of discerning these fine differences. The order of magnitude of these differences is so minute, in fact, that manufacturing equipment is incapable of manipulating or replicating them. Thus, the fine-grained manufacturing differences can act as a sort of a key to reliably distinguish each of the processors from one another.

The implication of this discovery is that such differences can be used as physically unclonable features to securely link the graphics cards, and by extension, the computers in which they reside and the persons using them, to specific online accounts."

Privately — and sometimes even publicly — long-time Microsoft partners took it as an attack on their businesses and questioned why Microsoft would be so brazen. But with nowhere else to turn thanks to Windows’ overwhelming PC dominance, these vendors had no choice but to continue developing Windows 8 devices and compete directly with their software supplier. Though events may play out a bit differently in the smartphone market where Microsoft has yet to stage the comeback it promised two years ago, BGR has learned that the Redmond, Washington-based company plans to release its own Windows Phone 8 smartphone in the coming months..."

One analyst firm has said Ultrabooks will only make up 5% of the market this year, slashing its own sales predictions from 22m this year to 10.3m. However, IHS iSuppli said that Ultrabooks have a chance at success if manufacturers get prices down between $600 to $700 — a discount of as much as $400 on the average selling price of the devices — and they could still grab a third of the laptop market by 2016."

During the course of their work, researchers produce e-mails, preliminary results, and peer reviews, all of which might be more confused or critical than the final published works. Recently, both private companies with a vested interest in discounting the results, and private groups with a political axe to grind have attempted to use the courts to get access to that material.

Would it be possible or wise to keep these documents private and immune to subpoenas? In the latest issue of Science, a group of researchers from the Woods Hole Oceanographic Institution (WHOI) argue that scientists need more legal rights to retain these documents and protect themselves in court."

The ban on the Galaxy Tab 10.1 had been placed before a month-long patent trial between Apple and Samsung. In August, at the conclusion of that trial Apple was awarded a victory on many of its patent violation claims where it said Samsung had copied Apple's iPhone and iPad designs. It was also awarded more than $1bn (£664m) in damages. However, the jury found that Samsung had not violated the patent that was the basis for the ban on the sale of the Galaxy Tab 10.1. Samsung, therefore, argued for the sales ban to be lifted"

It does so, by a noticeable margin in many cases over the HD 3000/4000 of Sandy Bridge and Ivy Bridge. The CPU results aren't as positive though with the combination of higher clocks and the new Piledriver core design only equating to ~20% better performance compared to Llano. With prices starting in the $125 range, the A10 APU should be an interesting choice for HTPC and super low cost gaming builds but will fall well behind Intel's x86 performance in Ivy Bridge."
