Why Computer Science Students Cheat 694

Posted by Soulskill from the your-comments-will-be-analyzed-for-plagiarism dept.
alphadogg writes "Enrollment in undergraduate computer science courses is at an all-time high at colleges nationwide. But this trend that's been hailed by the US tech industry has a dark side: a disproportionate number of students taking these courses are caught cheating. More students are caught cheating in introductory computer science courses than in any other course on campus, thanks to automated tools that professors use to detect unauthorized code reuse, excessive collaboration, and other forbidden ways of completing homework assignments. Computer science professors say their students are not more dishonest than students in other fields; they're just more likely to get caught because software is available to check for plagiarism. 'The truth is that on every campus, a large proportion of the reported cases of academic dishonesty come from introductory computer science courses, and the reason is totally obvious: we use automated tools to detect plagiarism,' explains Professor Ed Lazowska, chair of computer science and engineering at the University of Washington. 'We compare against other student submissions, and we compare against previous student submissions and against code that may be on the Web. These tools flag suspicious cases, which are then manually examined.'"

How Many Hours a Week Can You Program? 547

Posted by timothy from the please-answer-in-earth-hours dept.
An anonymous reader writes "How many hours a week should a full-time programmer program? Trying to program anywhere near 40 wears me out. On a good week, I can do 20. Often, it is around 10 or 15. I'm talking about your programming session at the console, typing — including, of course, stopping and thinking for a minute, but not meetings, reading programming books, notes, specifications, etc., which by comparison feel like lunch breaks. I rarely get called to meetings (which is good) but that means to keep my brain from overheating I spend several hours a week surfing the web (usually reading tech news but also a few stops on Facebook, email, etc.). I should add that I am interrupted a few times per day. Me and another guy maintain an intranet site of a couple dozen web apps for an IT department, so we work on a few different things: phone calls, bug fixes, feature adds, as well as writing new web apps from the ground up, all in a day's work. And I know that wears a person out more than if they had just one project to work on. I wonder if programming is like mental sprinting, not walking, so you can only do it in bursts. Am I normal or stealing?"

A New "Medical Lab On a Chip" For Every Home? 56

Posted by Soulskill from the a-mischievous-sibling-could-have-fun-with-this dept.
destinyland writes "NWU professor Chad Mirkin discusses his company's new 'lab-on-a-chip' technology — the ability to automatically treat a blood sample with chemicals on a microchip, quickly detecting markers for diseases and other anomalies. The quick 'bio-barcode' test creates the possibility of a medical diagnostic system in every home, since it offers greater sensitivity than current tests with simpler instruments and at lower costs. This is not a futuristic technology; four tests already have received FDA clearances, so 'They're here.... It's in hospitals around the country. Really, what we are waiting for is just an increasing menu [of tests]... It will scale rapidly.'" Reader Trintech sent word of a similar chip developed by Fraunhofer reseachers, writing, "The core element of this new chip is a disposable cartridge made of plastic which can be fitted with various types of sensors. To perform an assay, the doctor only has to place the relevant substances (reagents, etc.) into the cartridge and the test then takes place automatically. It is the researchers' hope that, by using this chip, medical patients will be able to get their lab results in a matter of minutes instead of days."
Operating Systems

Multicore Requires OS Rework, Windows Expert Says 631

Posted by timothy from the ok-let's-split-up dept.
alphadogg writes "With chip makers continuing to increase the number of cores they include on each new generation of their processors, perhaps it's time to rethink the basic architecture of today's operating systems, suggested Dave Probert, a kernel architect within the Windows core operating systems division at Microsoft. The current approach to harnessing the power of multicore processors is complicated and not entirely successful, he argued. The key may not be in throwing more energy into refining techniques such as parallel programming, but rather rethinking the basic abstractions that make up the operating systems model. Today's computers don't get enough performance out of their multicore chips, Probert said. 'Why should you ever, with all this parallel hardware, ever be waiting for your computer?' he asked. Probert made his presentation at the University of Illinois at Urbana-Champaign's Universal Parallel Computing Research Center."

Wolfenstein Being Recalled In Germany 625

Posted by Soulskill from the ach-mein-leben dept.
D1gital_Prob3 tips news that Activision's recently-released shooter, Wolfenstein, is being recalled in Germany due to the appearance of swastikas in the game. Such symbols are banned in Germany, and the German version of the game went through heavy editing to remove them. Apparently, they missed some. Activision said, "Although it is not a conspicuous element in the normal game ... we have decided to take this game immediately from the German market." Reader eldavojohn points out a review that has screenshot comparisons between the two versions of the game.

Soviets Built a Doomsday Machine; It's Still Alive 638

Posted by kdawson from the dead-hand dept.
An anonymous reader points out a story in Wired introducing us to the Doomsday Machine built by the Soviet Union in the 1980s — and that remains active to this day. It was called "Perimeter." The article explains why the device was built, and why the Soviets considered it to be something that kept the peace, even though they never told the US about it. "[Reagan's] strategy worked. Moscow soon believed the new US leadership really was ready to fight a nuclear war. But the Soviets also became convinced that the US was now willing to start a nuclear war. ... A few months later, Reagan... announced that the US was going to develop a shield of lasers and nuclear weapons in space to defend against Soviet warheads. ... To Moscow it was the Death Star — and it confirmed that the US was planning an attack. ... By guaranteeing that Moscow could hit back, Perimeter was actually designed to keep an overeager Soviet military or civilian leader from launching prematurely during a crisis. The point, [an informant] says, was 'to cool down all these hotheads and extremists. No matter what was going to happen, there still would be revenge. Those who attack us will be punished.'"

Comment depends on the college (Score 1) 835

At my University, the respective computer labs of each department is handled internally. When I take one of my rare strolls over to the humanities buildings, their workstations are almost completely Windows XP based machines. In my native CS department however, we have over 200 workstations that are running CentOS Linux distro. We do have a windows server that has remote login enabled. We also have an NX server running a linux remote login. We've got full ssh, ftp capabilities. A friend of mine works in psych department, and she has zero access to any linux or remote login capabilities. So, I would say the more technical your daughters particular field is, the more likely her specific college/major provides the resources she would enjoy.

Alan Turing Apology Campaign Grows 653

Posted by CmdrTaco from the he-only-invented-modern-computer-science dept.
chrb writes "Several British news sources have recently reported on the growing campaign that calls for an apology to Alan Turing for his persecution by the British government. The petition to the Prime Minister was started by John Graham-Cumming, who has also written to the Queen requesting a Knighthood for Turing, but admits that a pardon is 'unlikely,' saying, 'The most important thing to me is that people hear about Alan Turing and realize his incredible impact on the modern world, and how terrible the impact of prejudice was on him.'"

Up To 90 Percent of US Money Has Traces of Cocaine 441

Posted by CmdrTaco from the having-more-fun-than-me dept.
mmmscience writes "Scientists have found that up to 90% of US paper money has some cocaine contamination, up from the 67% mark measured two years ago. Looking at bills from 17 cities, it's no surprise that the city with the highest level was Washington DC, where up to 95% of bills gathered there tested positive. From a global standpoint, both Canada and Brazil tested rather high (85% and 80%, respectively), but China and Japan were well behind the curve at 20% and 12%. The researchers hope that studies such as these will be of help to law enforcement agencies that are attempting to understand the growth and flow of drug use in communities."

US Colleges Say Hiring US Students a Bad Deal 490

Posted by CmdrTaco from the talking-to-you-cliff dept.
theodp writes "Many US colleges and universities have notices posted on their websites informing US companies that they're tax chumps if they hire students who are US citizens. 'In fact, a company may save money by hiring international students because the majority of them are exempt from Social Security (FICA) and Medicare tax requirements,' advises the taxpayer-supported University of Pittsburgh (pdf) as it makes the case against hiring its own US students. You'll find identical pitches made by the University of Delaware, the University of Cincinnati, Kansas State University, the University of Southern California, the University of Wisconsin, Iowa State University, and other public colleges and universities. The same message is also echoed by private schools, such as John Hopkins University, Brown University, Rollins College and Loyola University Chicago."

Now this Malik guy is an internet celebrity, which is exactly what the article states is his desire. All of his actions have suddenly been validated, because hey, he's an internet star. Visits to prankster.com (or whatever, I don't know) probably just went through the roof, generating some ad revenue for him to pay for another full body massage at the corner-shop. Hundreds of jackass 15 year old imitators are already foaming at the mouth to copy these douchebags. While the article was hilarious in pointing out the creepy people behind prankster, they did them a huge favor by introducing them to the rest of the world.
