Comment Car Analogy! (Score 1) 129

Time for a car analogy! Cellular bandwidth is like the traffic on your morning commute. Recently there have been complaints of traffic jams, delays, and generally slow transit speeds. However, adding more lanes to the roads is expensive, so instead the road operator has come up with a fantastic solution. They will sell Turbo Boost buttons for drivers to install in their cars. If wielders of a turbo button feel that their commute is too slow, then by pressing the button they can technomagically force all other drivers to exit the lane the button user is driving in, thus clearing a fast path for them. Of course the lane changes aren't forced on other button wielders.

This amazing innovation is sure to solve the traffic problems in no time.

Comment Fix This With Add-Ons (Score 2) 352

This and many other privacy issues can and should be fixed by use of proper Firefox add-ons. Sure we can decry the practice and wish that in an ideal world corporations would not do such things, but that's a waste of time. Use things like Adblock Plus, Ghostery, Beef Taco, NoScript, and Better Privacy.

I don't even see those Facebook buttons. Since in practice nobody will manually mess with their cookies each time they log out of a site, and may even want to visit other sites while still logged in, this is the only realistic solution.

Comment Acts of War (Score 5, Insightful) 388

Oh. When we saw the story the other day that the US had declared that hacking and similar online attacks could be considered acts of war, I didn't understand the purpose of such a statement. Now I understand.

I think we might be seeing the start of America's next war on a general concept.

Any bets as to what the target will be stated as? Anonymity? The Internet in general?

Comment Re:Wow, Biased Summary Much? (Score 1) 93

The article makes clear that the comparison to desktop CPUs is being done to clear up corporate PR hyperbole. Although it's obvious to techies that a chip in this electrical/thermal segment can't compete with desktop processors that have many times the resources to work from, it's important for average users to have that cleared up.

However the article also makes clear that in the market segment this chip was actually designed for, it's a big success. This is of particular note since the Atom line had been dominating the segment for so long.

The summary makes it sound like this is some kind of failed desktop chip - definitely not the case.

Comment Wow, Biased Summary Much? (Score 5, Insightful) 93

Ok wait, so AMD's next-gen "atom-killer" successfully trumps Intel's next-gen Atom, but "the results aren't particularly encouraging" because it doesn't also beat full-fledged desktop processors? Seriously, talk about misleading.

In other news, iPods aren't the best at 3D graphics rendering, and cars are not the best choice for transatlantic shipping.

This is a test of CPU/GPU integration at the low end to start with - and a successful test at that.

Comment Way too expensive (Score 1) 179

It's easy to see that any system requiring special light fixtures and modems for each PC will be far more expensive than simply setting up a wireless access point or two for each floor of a building. This wouldn't even just be a one-time cost, but would apply as part of regular maintenance - which is easier, to swap out a router, or to bring in contractors to replace all of a company's light fixtures?

A system like this could really only be practical where conventional wireless can't be used for some reason. Perhaps in offices where security is the foremost consideration (CIA?), or a building right next to a high-powered radio broadcast tower.

Comment Why these types of reports get kept secret (Score 5, Insightful) 100

These types of reports are typically kept secret because in addition to stories that are totally made up, they could be a source of intelligence on military aircraft. When testing new yet easily observable capabilities (i.e. VTOL), you don't want foreign powers reading your citizens' UFO sighting reports to judge how far along you are, or for that matter even to track down which airfields are being used to test prototype craft. In some cases depending on local geography and political relations, the reports might even contain information on craft of neighbouring nations.

"But the most important thing is they don't challenge you. You don't even have to explain what you want or provide a document."

Wow, I think this is just about the worst advice I can imagine.

Apparently, so long as the programmers "don't challenge you" by asking you to "explain what you want", all your IT projects will be wild successes!

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.
