Comment DSL Is Not That Simple (Score 1, Insightful) 332

While this is a common view of how DSL technology works, it's really only true in dense urban areas with relatively new wiring. The truth is that it's actually quite complex to transmit broadband signals over telephone lines, and any number of things can interfere.

For starters, in most cases the DSLAM has to be within about 3 miles of the customer, and this is not measured as a bird flies. Sometimes the wires may twist around in all sorts of bizarre ways depending on historical construction. This makes it extremely costly for telecoms to provide broadband outside of densely populated areas, since you're looking at installing a DSLAM and the facilities to protect, support, and maintain it for a handful of houses in some rural areas. There's no way for those costs to ever be recovered. Now there are some ways to cut these costs using remote terminals rather than full DSLAMs, but this still costs vastly more than the customers can repay.

Although plain old distance-based attenuation is the biggest limiting factor, there are all kinds of other problems as well. Things like the gauge of the telephone wiring can make a big difference, and many areas historically had signal-boosting equipment installed on phone lines which produces acceptable voice quality on a flaky line, but makes broadband signal transmission all but impossible. At that point telecoms are looking at major engineering work to remove that equipment without degrading voice quality for the affected customers, all before they can even think about providing broadband service.

Without addressing these major engineering issues first, the most common results of offering broadband to customers in these areas is that they get 1/10th of the intended speed and the service cuts out every 10 minutes due to attenuation and poor signal to noise ratio. This predictably results in furious customers and repair techs trying to patch things together on an individual customer basis, and usually failing since these tend to be major jobs that can't just be fixed with duct tape. So generally the telecoms simply don't offer the service in these areas because they don't want the hassle.

Now don't get me wrong, I'm no shill for the telecoms. I know all about federal funding they've received which has gone to questionable use, and there are various things I think should be done differently. However, looking purely at the technology involved, it is not in any way a simple task to roll out rural broadband. Pretending it's easy won't help anyone; it can be done, but it will take a long time and cost a lot of money. Even assuming unlimited funding I doubt it could be finished by 2012, simply because there aren't enough field techs/engineers to complete the vast amount of requisite infrastructure work in that timeframe.

The primary benefit we get out of NASA and similar agencies is not the science done in orbit around Jupiter or Saturn. Sure we can learn some interesting stuff that way, but ultimately the exact composition of Titan will have almost zero beneficial effect on human life.

The primary benefit is that in solving very difficult engineering problems, NASA produces interesting solutions which may also be applicable to related terrestrial issues. These resulting spinoffs are much more valuable.

Eliminating human spaceflight would make things a lot easier. That's the problem. You learn less from something that's easy.

You're looking for Runescape. It's designed so that you can fight using melee, magic, or ranged/archery depending on your preference of the day, and you can eventually master all three. Similar with non-combat skills. In fact a few upper-level monsters and bosses are designed such that to defeat them you must switch combat styles mid-fight by swapping out your equipment.

Seriously guys, anyone blaming MySpace for this isn't grasping what has happened. This is like if you are going bankrupt, so you hold a yard sale to pay off your debts. John Doe buys some of your stuff. In the end you still can't pay all your debts, so the people you haven't paid go after the guy who stopped by your yard sale? Wait, what?

Submission + - Ten Things Mobile Phones Will Make Obsolete

An anonymous reader writes: recombu.com has an article examining ten things mobile phones will make obsolete, including phone booths, wristwatches and handheld games consoles. It's interesting to see how many devices have been absorbed into mobile phone technology and it begs the question, are we better off having everything in one device? The author poignantly concludes that while it's great to have so much power at our fingertips it does mean that some of us will rely on mobile phones for even basic mental tasks, which is great until the battery runs out.

Submission + - Cisco Shareholders in Revolt over Exec Pay (internetnews.com)

darthcamaro writes: Cisco has been busy lately buying up companies left and right. They've also managed to layoff 2,000 people and pay their top exec more this year than last, even though the company is making less money. Shareholders are not impressed, and a coalition led by a Christian faith group is leadering the charge.

"As investors in Cisco, we have received earnings that help us to support our members in some of the poorest places in this world where the inequities of our current economic system are most dramatically exposed," Sister Mary Pat LeRoy of the Sisters of the Holy Names said during Cisco's Annual General Meeting. "We see executive compensation as a justice issue for our time." /blockquote?

Submission + - Universal 'Death Stench' Repels Bugs of All Types

pickens writes: Hugh Pickens writes

Wired reports that scientists have discovered that insects from cockroaches to caterpillars all emit the same stinky blend of fatty acids when they die and that the death mix may represents a universal, ancient warning signal to avoid their dead or injured. "Recognizing and avoiding the dead could reduce the chances of catching the disease," says Biologist David Rollo of McMaster University "or allow you to get away with just enough exposure to activate your immunity." Researchers isolated unsaturated fatty acids containing oleic and linoleic acids from the corpses of dead cockroaches and found that their concoction repelled not just cockroaches, but ants and caterpillars. "It was amazing to find that the cockroaches avoided places treated with these extracts like the plague," says Rollo. Even crustaceans like woodlice and pillbugs that diverged from insects 400 million years ago were repelled leading scientists to think the death mix represents a universal warning signal . Scientists hope the right concoction of death smells might protect crops and thankfully, human noses can't detect the fatty acid extracts. "I've tried smelling papers treated with them and don't smell anything strong and certainly not repellent," writes Rollo in an e-mail. "Not like the rotting of corpses that occurs later and is detectable from great distances,."
