Good Language Choice For School Programming Test? 407

Posted by timothy from the 'strailian's-too-difficult dept.
An anonymous reader writes "The Australian Informatics Olympiad programming test is being run in a couple of months. I'm an experienced programmer and I'm thinking of volunteering to tutor interested kids at my children's school to get them ready. There will be children of all levels in the group, from those that can't write 'hello world' in any language, to somewhat experienced programmers. For those starting from scratch, I'm wondering what language to teach them to code in. Accepted languages are C, C++, Pascal, Java, PHP, Python and Visual Basic. I'm leaning towards Python, because it is a powerful language with a simple syntax. However, the test has a run-time CPU seconds limit, so using an interpreted language like Python could put the students at a disadvantage compared to using C. Is it better to teach them something in 2 months that they're likely to be able to code in but possibly run foul of the CPU time limit, or struggle to teach them to code in a more complicated syntax like C/C++ which would however give them the best chance of having a fast solution?"

Qutrits Bring Quantum Computers Closer 66

Posted by kdawson from the shortcut-through-higher-dimensions dept.
KentuckyFC writes "To do anything useful with quantum logic gates, you need dozens to hundreds of them, all joined together. And because of various errors and problems that creep in, that's more or less impossible with today's technology. Now an Australian group has built and tested logic gates that convert qubits into qutrits (three-level quantum states) before processing and then convert them back again. That makes them far more powerful. The group says that a quantum computer that might require 50 conventional quantum logic gates can now be built with just 9 of the new gates. What's more, the gates process photons using nothing more than standard linear optical components (abstract on the physics arxiv)."

bowman9991 writes "Peter Berg will be directing a new big-budget Dune movie from Paramount. SFFMedia reports that 'although there were some doubts that they were going to get it,' the producers have secured the rights to the Dune novel from Frank Herbert's estate and are looking for writers to provide a screenplay that is true to the original text. Can't wait!"

Adobe Photoshop CS4 Will Be 64-Bit For Windows Only 478

Posted by kdawson from the takes-time-to-make-a-cup-of-cocoa dept.
HighWizard notes that Adobe Systems has shared the first scrap of information about its next version of Photoshop, CS4, and it's a doozy: there will be a 64-bit version of the photo-editing software, but only for Windows Vista and not for Mac OS X. Ars explains the history of how this conundrum came to pass — blame Apple and/or Adobe as you will.

Google Plans To Sell Part of DoubleClick 61

Posted by Soulskill from the look-we're-not-evil-see dept.
mudimba writes "Google has announced that they will be selling the search engine marketing branch of recently acquired company DoubleClick. Google's reason for the sale is that they do not want to appear to be giving preferential treatment in search rankings to DoubleClick customers. Tom Phillips, director of Google's integration with DoubleClick, said, 'Maintaining objectivity in both search and advertising is paramount to Google's mission and core to the trust we ask from our users.' Google was under scrutiny from the European Union and the FTC over their purchase of DoubleClick, but both eventually approved the deal."

Net Neutrality Debate Intensifies In Canada 163

Posted by Soulskill from the something-to-talk-about-until-the-hockey-playoffs dept.
MrShaggy tips us to news that the debate over Net Neutrality in Canada is coming to the forefront following the recent discovery that Bell Canada was throttling P2P traffic on the access it had sold to wholesalers. Michael Geist's blog notes a video recording of comments from a member of the Canadian government, as well as coverage from Canadian media. From Ars Technica: "The Canadian government has in the past pushed the CRTC to deregulate the telecom industry, an approach still backed by Minister of Industry Jim Prentice. Prentice also wants to stay out of the current net neutrality debate, which would seem to be a de facto vote against the idea. He was asked in the House of Commons this week whether his government would do anything about the current Bell/Rogers traffic-shaping controversy. According to the Globe & Mail, Prentice said only that "we will continue to leave the matter between consumers on the one hand and Internet service providers on the other."

IBM Using Complex Math To Manage Natural Disasters 115

Posted by Soulskill from the stopping-a-flood-with-natural-logs dept.
coondoggie brings us a NetworkWorld story about IBM's efforts to use complex algorithms to manage responses to natural disasters. Researchers are making use of recent increases in processor speed and algorithm efficiency to develop a scalable, flexible model capable of handling the complicated planning involved in reacting to a crisis. Quoting: "'We are creating a set of intellectual properties and software assets that can be employed to gauge and improve levels of preparedness to tackle unforeseen natural disasters,' says Dr. Gyana Parija. 'Most real-world problems involve uncertainty, and this has been the inspiration for us to tackle challenges in natural disaster management.' In the case of flooding, for example, the stochastic programming model would use various flood scenarios, resource supply capabilities at different dispatch locations, and fixed and variable costs associated with deployment of various flood-management resources to manage various risk measures. By assigning probabilities to the factors driving outcomes, the model outlines how limited resources can meet tomorrow's unknown demands or liabilities. In this way, the risks and rewards of various tradeoffs can be explored, IBM said."

Having Your ID Stolen Leads to Job Loss, Prosecution 404

Posted by Zonk from the jobs-are-for-living-though dept.
ConfusedVorlon writes "The BBC reports on the sad case of Simon Bunce. Mr. Bunce had his identity stolen, and credit cards were made to capitalize on the theft. Some of those cards were used at sites offering child pornography, and as a result Mr. Bunce was swept up in Operation Ore. The poor man was prosecuted for his 'crime', and was eventually found innocent, but in the meantime he lost his job. It took him six months to find another at a quarter of the salary. 'The police's computer technicians take several months to examine [his computers and records], and Mr Bunce could not afford to wait to repair the damage done to his reputation. "I knew there'd been a fundamental mistake made and so I had to investigate it." Recent surveys suggest that as many as one in four Britons have been affected by it. In 2007 more than 185,000 cases of identity theft were identified by Cifas, the UK's fraud prevention service, an increase of almost 8% on 2006.'"

Engineers Make Good Terrorists? 467

Posted by Zonk from the what's-wrong-with-an-engineering-degree dept.
An anonymous reader writes "Engineers' focus and attention to details, along with their perceived lack of social skills, make them ideal targets to be recruited as terrorists, according to EETimes. Planning skills make engineers good 'field operatives' was written up by Raphael Perl, who heads the Action against Terrorism Unit of Organization for Security and Cooperation in Europe. He offers that 'Engineers ideally make excellent strategic planners, and they make excellent field operatives. They think differently from how other people think.' That may sound like a stereotype, but Perl claims that 'because of those traits, terrorist groups actively recruit engineers.' He says that Al-Qaeda has widely acknowledged that a significant number of the group's top leadership had engineering backgrounds." This is the second time in just a few months that engineers have been likened to terrorists.

Feed Intel reveals quad-core laptop chip in the pipeline for 2008 (engadget.com)

From feed by engfeed

Filed under: Gaming, Laptops

Confirming something that we had already seen hints of, Intel has announced that it is looking forward to quad core laptops hitting the scene throughout 2008. Mooly Eden, GM of Intel's mobile platform group, said that we won't see these quad cores in business class laptops for a while, even being honest enough to admit that there aren't enough multi-threaded applications out there to justify it. In practically the same breath, PC World mentions that the chip will target high-level gaming laptops, which is cool because gamers will no doubt lap the new chips up: even if gaming is for the moment a very much single-threaded activity. Architecturally the new chip will have to differ from Intel's current offerings such as Santa Rosa, so you can probably expect to pay quite a premium until they hit the mainstream. (Not that you didn't know that already.)

Submission + - Putin Threatens US Missile Bases in Europe (forbes.com)

Submitted by

Melugo writes: "Russian President Vladimir Putin warned that U.S. plans to build a missile defense system in Eastern Europe would force Moscow to target its weapons against Europe. "If the American nuclear potential grows in European territory, we have to give ourselves new targets in Europe," Putin said, according to Corriere. "It is up to our military to define these targets, in addition to defining the choice between ballistic and cruise missiles." It feels like the Cold War all over again.
