Largest and Most Intense Tropical Cyclone On Record Hits the Philippines 160

mrspoonsi writes "A monstrous storm has arisen in the Western Pacific. The storm, called 'Supter-Typhoon Haiyan', has become the year's most intense. It bore down on the central Philippines this morning, packing winds up to 195 mph (314 km/h), with gusts up to 235 mph (378 km/h), threatening massive damage and sending over 100,000 people into evacuation centers. (Animation of landfall.) Flood waters went as high as 10 feet. The secretary general of the Philippine National Red Cross said, 'About 90% of the infrastructure and establishments were heavily damaged.'"

Comment Re:"New" high gain antennae? (Score 5, Insightful) 104

Directional antennas are not new. But configuring an array of directional antennas to precisely cover the seats in the lecture hall to minimize the number of users on any single access point is a new and novel way to deploy wireless access.

Deploying the same number of omnidirectional antennas in the same space would lead to massive overlap, interference, and clients unnecessarily switching between APs when they perceived a stronger signal from a different AP.

I haven't heard of a high density environment purposely set up this way therefor I think it is indeed newsworthy.

* For example, schoolchildren having to cover their ears several times per hour due to the large number of painfully loud low-flying aircraft that pass endlessly pass overhead.

Citation? Where do Japanese schoolchildren have to cover their ears several times each hour? Where is this schoolhouse that can't be relocated from the end of some flightpath? This schoolhouse has been subject to some loud jet noise for over 50 years and they haven't moved it? Or is this an attempt to drum up some anti-military sentiment? (Wikipedia only lists 39 overseas Air Force locations not counting the ones closing in Afghanistan.)

And nothing of value was lost. Or gained.

Nothing was lost? All the work that the government workers could have been doing during the shutdown was lost. All the revenue from the National Parks were lost. Two weeks food inspections, drug inspections, VA claims processing were lost . Worldwide confidence in the US and the US dollar was lost. US credit rating was compromised with the possibility of higher interest rates on new deficit. Scientific tests will have to be thrown out and restarted.

You might not be personally affected, but plenty of money and confidence has been lost during the past three weeks.

Last night I sent my Gmail account an email from my ISP email system, then waited for it to show up. Nothing. So I resent it. Second time nothing.

The email contained two screen captures I needed at the office. The subject line was "Steve on telework". Nothing obvious that would trip Postini's spam filter. It is now 24 hours later and neither has shown up. I wonder how many other emails I don't get.

I also tried converting from PDF to EPUB. Sometimes the PDF isn't in a good condition and I get a very poor EPUB. If that happens, I convert PDF -> RTF, clean up and spell check in MS Word, then RTF -> EPUB.

This has let me fix over-large graphics, incorrect page breaks, constant spelling problems from the OCR, and font problems.

Submission + - Most Veterans Administration Data Breaches from Mislaid Paper Documents (informationweek.com)

CowboyRobot writes: "Between 96 and 98 percent of our [data breach] incidents — it varies from month to month — deal with physical paper where people are not thinking about the fact that that piece of paper they're carrying around making benefits determinations has sensitive information and they need to protect it," said Stephen Warren, VA acting assistant secretary for information and technology. "If you consider the fact the VA has about 440,000 people that we service and that the department over 900,000 devices on the network, [a data breach count relating to IT assets] of somewhere between one and 10 in a month is pretty good," Warren said. "And many of those are things disappearing in inventory. Many are found subsequently because they got moved somewhere."

You still don't understand RP propagation. Having an antenna receive a signal does not diminish the strength of the signal behind it any more than a metal light pole diminishes it. Both will cause a slight disturbance in the transmitted signal, but the rest of the signal will still continue past it. You can't calculate how many devices are receiving an RF signal by measuring field strength at a fixed distance.

Think of throwing a pebble into a pond and watching the waves travel outward. If you put a stick in the water, it will disrupt the wave slightly, but the rest of the wave continues radiating outward. The small amount of energy that the stick receives is so miniscule compared to the total circular wave, it can be thought of as zero. (Well, if the stick is 10 feet away from the source it intersects a circle more than 60 feet in circumference. A one-inch stick would disrupt 1/750th of the circle. 20 feet away? 1/1500th of the total circumference.) Plus, RF propagates in three dimensions, not just two.

And your proof? You suggest putting enough barriers around the transmitting antenna to capture all the radiated energy to gain back more than you started with. First, you would never effectively capture it all, unless you built a Fariday Cage around the transmitter. Plus you ignore the power loss in converting the RF power back to electricity. You can't prove your point by suggesting if you are wrong we would have perpetual energy.

One possible reason that things aren't going according to plan is that there never was a plan in the first place.
