The Best First Language For a Young Programmer 634

snydeq writes "Fatal Exception's Neil McAllister questions whether Scheme, a dialect of Lisp taught as part of many first-year CS curricula and considered by some to be the 'latin of programming,' is really the best first language for a young programmer. As he sees it, the essentially write-only Scheme requires you to bore down into the source code just to figure out what a Scheme program is trying to do — excellent for teaching programming but 'lousy for a 15-year-old trying to figure out how to make a computer do stuff on his own.' And though the 'hacker ethic' may in fact be harming today's developers, McAllister still suggests we encourage the young to 'develop the innate curiosity and love of programming that lies at the heart of any really brilliant programmer' by simply encouraging them to fool around with whatever produces the most gratifying results. After all, as Jeff Atwood puts it, 'what we do is craftmanship, not engineering,' and inventing effective software solutions takes insight, inspiration, deduction, and often a sprinkling of luck. 'If that means coding in Visual Basic, so be it. Scheme can come later.'"

Submission + - Phantom OS, the 21st Century OS?

jonr writes: Phantom doesn't have files. Well, there are no files in the sense that a developer opens a file handle, writes to it, and closes the file handle. From the user's perspective, things still look familiar — a desktop, directories, and file icons. But a file in Phantom is simply an object whose state is persisted. You don't have to explicitly open it. As long as your program has some kind of reference to that object, all you need to do is call methods on it, and the data is there as you would expect.

This is what has been bugging me for years. Why, in the year 2009, after 50 years of OS development, are we still opening and closing files manually? Why don't we just edit data in memory and let the OS handle the physical storage?

Making Magnetic Monopoles and Other Physics Exotica 104

PhysicsDavid writes "Physicists have been searching for magnetic monopoles pretty much since they knew about magnetism and definitely since Maxwell unified electricity and magnetism. Now some researchers have shown that using some weird mirror materials will allow them to create something indistinguishable from a monopole in a lab experiment. A paper about it was published today in the journal Science as an advance online publication (abstract; full article available only to AAAS members). The technique looks like it could be used to create analog systems of other kinds of exotic particles that haven't yet been observed, such as axions. The theorists who proposed this are working with experimenters to try to create these systems and study them in depth this year."

If Windows 7 Fails, Citrix (Not Linux) Wins 638

Julie188 writes "Microsoft blogger Mitchell Ashley, who has been using Windows 7 full-time, predicts that Windows 7 will fail to lure XP users away from their beloved, aging operating system — after all, Windows 7 is little more than what Vista should have been, when it shipped two years ago. But eventually old PCs must be replaced and then we'll see corporations, desperate to get out of the expense of managing Windows machines, get wise. Instead of buying new Windows 7 PCs, they could deliver virtualized XP desktops to a worker's own PC and/or mobile device. Ashley believes that Citrix's Project Independence has the right idea."

Fusion-Fission System Burns Hot Radioactive Waste 432

An anonymous reader writes "A hybrid fission-fusion process has been developed that can be used in some traditional fission reactors to process radioactive waste and reduce the amount of waste produced by 99%. This process uses magnetic bottle techniques developed from fusion research. This seems like the first viable solution to the radioactive waste problem of traditional nuclear reactors. This could be a big breakthrough in the search for environmentally friendly energy sources. Lots of work remains to take the concept to an engineering prototype and then to a production reactor."

"Subhuman Project" Human Powered Submarine 103

"Inventor Ted Ciamillo and marine biologist Frank Fish (yes, that's his real name) are at work on a human-powered sub designed to cross the Atlantic. What's interesting is the highly efficient propulsion system which uses a 'tail' modeled after CAT scans of a dolphin's. From the article: 'Ciamillo and Fish say they knew they were onto something when the first prototype Lunocet, a piece of sculpted foam sandwiched between two pieces of carbon fiber, essentially swam by itself. When they released it at the bottom of a test pool, its buoyancy combined with its cambered shape generated a forward thrust that made it scoot across the tank.'"

Alaskans Prepare For Volcanic Eruption 293

An anonymous reader writes "Mount Redoubt, or Redoubt Volcano, is an active stratovolcano in the largely volcanic Aleutian Range of Alaska. The once quiet volcano has begun to roar once again. Its last eruption was in 1989 and geologists suggest that the next one is upon us. Alaskans who lived through the earlier eruption are stocking up on breathing masks and goggles. Starting on Friday, January 23 2009, the level of seismic activity increased markedly, and on Sunday AVO raised the Aviation Color Code to ORANGE and the Volcano Alert Level to WATCH. On the basis of all available monitoring data AVO regards that an eruption similar to or smaller than the one that occurred in 1989-90 is the most probable outcome. We expect such an eruption to occur within days to weeks." From the AP article: "Alaska's volcanoes are not like Hawaii's. 'Most of them don't put out the red river of lava,' said the observatory's John Power. Instead, they typically explode and shoot ash 30,000 to 50,000 feet high — more than nine miles — into the jet stream. 'It's a very abrasive kind of rock fragment,' Power said. The particulate has jagged edges and has been used as an industrial abrasive. 'They use this to polish all kinds of metals,' he said." The server for the Alaska Volcano Observatory appears to be overloaded and is unresponsive.

India Will Show Its $10 Laptop Prototype 374

Tech Ticker writes "The Indian Government last year announced the development of a cheap $10 laptop, but was later rectified as $100 laptop. Now the government has announced that HRD minister Arjun Singh will unveil the prototype of a Rs. 500 ($10) computer. The computer is developed by the Indian Institute of Science (IISc), Bangalore, and Indian Institute of Technology (IIT), Chennai. No specifications were revealed but DNA, a daily newspaper, has mentioned that it will be small and portable, will feature Wi-Fi, LAN, and expandable memory, and will operate on 2 watts of power."

Power In Scotland From Tides and Whiskey 170

tsamsoniw writes "Singapore-based Atlantis Resources Corporation, which brings to the table tidal-turbine technology, is partnering with Scotland-based datacenter developer Internet Villages International) to construct a tidal-powered 150MW 'Blue Datacenter,' InfoWorld reports. If all goes to plan, the facility will eventually be powered entirely by clean energy produced by tidal-current turbines in the Pentland Firth, the stretch of water between the far north Scottish mainland and Orkney. The firth's currents could generate 700 megawatts of electricity by 2020." And reader Mike writes "Here's something to raise a glass to: recently the Rothes consortium of whiskey and scotch distillers announced that they have partnered with Helius Energy to install a power plant fueled entirely by whiskey by-products. The completed plant will use biomass cogeneration to convert draff and pot ale from the distillery into 7.2 MW of electricity — enough to power 9,000 homes."

DRM Shuts Down PC Version of Gears of War 598

carlmenezes writes "It seems that the DRM on the PC version of Gears of War came with a built-in shut-off date; the digital certificate for the game was only good until January 28, 2009. Now, the game fails to work unless you adjust your system's clock. What is Epic's response? 'We're working on it.'"

More Websites Offending Thai Monarchy Blocked 220

An anonymous reader writes "Thailand is ramping up their media wide censorship of anything that remotely offends Thai royalty. In the last three weeks, another 2,300 websites have been blocked. Another ~4,000 are soon expected. And not just websites, but books as well as the Economist have been blocked. And anyone caught publishing such material, including foreigners, will get 3 to 15 years in a Thai prison. You don't want to be in a Thai prison!"

Charter Launches 60 Mbps Service 299

ndogg writes "While other companies are throttling their services, and capping bandwidth, Charter Communications, the cable company, is launching a 60/5 Internet service, starting in St. Louis, MO. It's certainly not cheap, starting at 129.99 per month (add another 10 if it's not being bundled with television or phone.) Currently, it's the fastest down stream speed available, and being a cable company, they potentially have greater reach than FiOS." However, there may be a risk to putting too much money down on this service; Charter Communications as a company faces some serious financial problems right now. As reader Afforess writes, "rumors abound that Paul Allen may just cut his losses and run," by selling the company. (Allen is the majority stockholder.)

Scientists "Teleport" Quantum Information One Meter 107

the4thdimension writes "While we may not be beaming up to the Enterprise anytime soon, a team of scientists from the University of Maryland and the University of Michigan have managed to teleport information between two atoms up to a meter apart. Until this point, only very tiny distances were able to be traveled. However, using a complicated system of photons, ions, lasers, and electromagnetics, scientists have managed to 'teleport' information contained on one atom to another atom that is in a separate sealed container. This can lead to a wide range of developments in computing and communications." Update: 01/29 22:29 GMT by T : Sorry, it's a dupe, but today's article in Time is better reading than the abstract anyhow.
