A good legal ruling: "FEC Won't Regulate Internet Politics"
[T]he Federal Election Commission unanimously adopted a rule requiring anyone placing a paid political ad on a Web site to abide by federal campaign spending and contribution limits.

But the rule also updates existing FEC regulations to make it clear that all other Internet political activity, such as blogging, e-mail communications and online publications, is not covered by the campaign law.

"Individual online political activity will be protected from FEC restriction regardless of whether the individual acts alone or as part of a group, and regardless of whether the individual acts in coordination with a candidate or acts independently," said Commission Chairman Michael E. Toner...

...Under the new rule, bloggers on the Internet would be entitled to the same exemption from the campaign finance law that newspapers and other traditional forms of media have long received. "There will be no second class citizens among members of the media," Toner said.

Invention of the day: A specialized microchip that facilitates neuron-to-computer interfacing.
The computer chip is capable of receiving signals from more than 16,000 mammalian brain cells, and sending messages back to several hundred cells. Previous neuron-computer interfaces have either connected to far fewer individual neurons, or to groups of neurons clumped together.

A team from Italy and Germany worked with the mobile chip maker Infineon to squeeze 16,384 transistors and hundreds of capacitors onto an experimental microchip just 1mm squared. When surrounded by neurons the transistors receive signals from the cells, while the capacitors send signals to them.

Nice review of Benford's Law. From the article:
Dr. Theodore P. Hill asks his mathematics students at the Georgia Institute of Technology to go home and either flip a coin 200 times and record the results, or merely pretend to flip a coin and fake 200 results. The following day he runs his eye over the homework data, and to the students' amazement, he easily fingers nearly all those who faked their tosses.

"The truth is," he said in an interview, "most people don't know the real odds of such an exercise, so they can't fake data convincingly."

There is more to this than a classroom trick.

Dr. Hill is one of a growing number of statisticians, accountants and mathematicians who are convinced that an astonishing mathematical theorem known as Benford's Law is a powerful and relatively simple tool for pointing suspicion at frauds, embezzlers, tax evaders, sloppy accountants and even computer bugs.

The income tax agencies of several nations and several states, including California, are using detection software based on Benford's Law, as are a score of large companies and accounting businesses.

"How Babies Learn Their First Words".
Ode to duct tape: This interesting article covers many of the unorthodox uses of duct tape, detailing some of its life-saving applications in medicine, the outdoors, etc. One interesting tidbit,
Of course, for all its versatility, perhaps the most interesting thing about duct tape is also the most ironic: It's lousy for use on ducts.

In 1998, Lawrence Berkeley National Laboratory physicists Max Sherman and Lain Walker tested a variety of sealing materials on sheet metal ducting, then heated and cooled the ducts to simulate the aging process. They soon found that duct tape leaked air so badly much of the cooling and heating was wasted -- and that the tape frequently shrunk, dried up or separated.

"It failed reliably and often quite catastrophically," says Sherman. "And nothing else except duct tape failed."

Why you shouldn't start a family fight on the internet:
Two weeks ago Steve Williams became so fed up with his daughter's messy bedroom that he built a website featuring pictures of his slothful offspring's lair in an attempt to shame her into action.

But the public humiliation proved a short-lived victory. While it did spur his daughter, Claire, into tidying up her room, it also whet her appetite for revenge. With the help of her father's friends, the 20-year-old business student has now set up a rival website that displays photos of him in a variety of compromising situations.

The commercial space tourism race is heating up.
Moore's Law for razor blades:
...Twin blades seemed plausible. Three were a bit unlikely. Four, ridiculous. And five seems beyond the pale. Few people, though, seem willing to bet that Gillette's five-bladed Fusion is the end of the road for razor-blade escalation. More blades may seem impossible for the moment -- though strictly speaking the Fusion has six, because it has a single blade on its flip-side for tricky areas -- but anyone of a gambling persuasion might want to examine the relationship between how many blades a razor has, and the date each new design was introduced.

This relationship (see chart) suggests shavers are going to get more blades whether they need them or not. However, just like Moore's law -- the observation that computer chips double in power every 18 months or so -- it seems that technology as well as marketing determines the rate at which new blades are introduced...

...So what does the future hold? With only five data-points, it is hard to be sure exactly which mathematical curve is being followed. If it is what is known as a power law, then the 14-bladed razor should arrive in 2100.
Of course this story from The Onion anticipated real-world developments by over 18 months.
"Microsoft Confirms it Originated iPod Box Parody Video".
Microsoft spokesman Tom Pilla on Tuesday confirmed with iPod Observer that his company initiated the creation of the iPod packaging parody video that was first reported last month. "It was an internal-only video clip commissioned by our packaging [team] to humorously highlight the challenges we have faced RE: packaging and to educate marketers here about the pitfalls of packaging/branding," he said via e-mail.

The video, which surfaced on You Tube but has since been removed and can now be found on Google Video, pokes fun at Microsoft's tendency toward cluttered packaging by imagining how the company would have designed the box for the original iPod. Where Apple's design is sparse, Microsoft's final creation is full of so many stickers and other information that the photo of the MP3 player can be barely seen.

LODI, Calif. -- A Lodi man is suing the city for driving a dump truck into his car. The strange thing is that he was the city employee driving the truck.

Rhonda Gokey's claim is for $1,200 more than Curtis'. She said that she is not as nice as her husband.

Maybe we should be worried about RFID viruses.
Up until now, everyone working on RFID technology has tacitly assumed that the mere act of scanning an RFID tag cannot modify back-end software, and certainly not in a malicious way. Unfortunately, they are wrong. In our research, we have discovered that if certain vulnerabilities exist in the RFID software, an RFID tag can be (intentionall) infected with a virus and this virus can infect the backend database used by the RFID software. From there it can be easily spread to other RFID tags. No one thought this possible until now. Later in this website we provide all the details on how to do this and how to defend against it in order to warn the designers of RFID systems not to deploy vulnerable systems...

To make clear what kinds of problems might arise from RFID hacking by amateurs or criminals, let us consider three possible and all-too-realistic scenarios.

1. A prankster goes to a supermarket that scans the purchases in its customers' shopping carts using the RFID chips affixed to the products instead of their bar codes. Many supermarkets have plans in this direction because RFID scans are faster (and in some cases can be done by the customers, eliminating the expense of having cashiers). The prankster selects, scans, and pays for a nice jar of chunk-style peanut butter that has an RFID tag attached to it. Upon getting it home, he removes or destroys the RFID tag. Then he takes a blank RFID tag he has purchased and writes a exploit on it using his home computer and commercially available equipment for writing RFID tags. He then attaches the infected tag to the jar of peanut butter, brings it back to the supermarket, heads directly for the checkout counter, and pays for it again. Unfortunately, this time when the jar is scanned, the virus on its tag infects the supermarket's product database, potentially wreaking all kinds of havoc such as changing prices.

2. Emboldened by his success at the supermarket, the prankster decides to unwittingly enlist his cat in the fun. The cat has a subdermal pet ID tag, which the attacker rewrites with a virus using commercially available equipment. He then goes to a veterinarian (or the ASPCA), claims it is stray cat and asks for a cat scan. Bingo! The database is infected. Since the vet (or ASPCA) uses this database when creating tags for newly-tagged animals, these new tags can also be infected. When they are later scanned for whatever reason, that database is infected, and so on. Unlike a biological virus, which jumps from animal to animal, an RFID virus spread this way jumps from animal to database to animal. The same transmission mechanism that applies to pets also applies to RFID-tagged livestock.

3. Now we get to the scary part. Some airports are planning to expedite baggage handling by attaching RFID-augmented labels to the suitcases as they are checked in. This makes the labels easier to read at greater distances than the current bar-coded baggage labels. Now consider a malicious traveler who attaches a tiny RFID tag, pre-initialized with a virus, to a random person's suitcase before he checks it in. When the baggage-handling system's RFID reader scans the suitcase at a Y-junction in the conveyor-belt system to determine where to route it, the tag responds with the RFID virus, which could infect the airport's baggage database. Then, all RFID tags produced as new passengers check in later in the day may also be infected. If any of these infected bags transit a hub, they will be rescanned there, thus infecting a different airport. Within a day, hundreds of airport databases all over the world could be infected. Merely infecting other tags is the most benign case. An RFID virus could also carry a payload that did other damage to the database, for example, helping drug smugglers or terrorists hide their baggage from airline and government officials, or intentionally sending baggage destined for Alaska to Argentina to create chaos (e.g., as revenge for a recently fired airline employee).

About 4,000 students who took the main SAT college entrance exam last October received incorrectly low scores because of problems with the scanning of their answer sheets...

Admissions officials, however, said Tuesday some students had been affected by as much as 130 points -- forcing schools to scramble to re-evaluate candidates at a time when many are trying to make final decisions.

"Caller ID spoofing becomes all too easy".
In the last few years, Caller ID spoofing has become much easier. Millions of people have Internet telephone equipment that can be set to make any number appear on a Caller ID system. And several websites have sprung up to provide Caller ID spoofing services, eliminating the need for any special hardware.

For instance, Spoofcard.com sells a virtual "calling card" for $10 that provides 60 minutes of talk time. The user dials a toll-free number, then keys in the destination number and the Caller ID number to display. The service also provides optional voice scrambling, to make the caller sound like someone of the opposite sex.

Caller ID spoofing appears to be legal, though many of its uses are not. The Federal Communications Commission has never investigated the issue, spokeswoman Rosemary Kimball said.

Lance James, chief scientist at security company Secure Science, said Caller ID spoofing websites are used by people who buy stolen credit card numbers. They will call a service such as Western Union, setting Caller ID to appear to originate from the card holder's home, and use the credit card number to order cash transfers that they then pick up.

"Russia plans to hit a golf ball into Earth orbit from the International Space Station. If NASA approves the plan, the ball would set records for the longest drive ever made -- but some experts warn that a mishap could cause "catastrophic" damage to the station."
The plan is part of a commercial deal between the Russian space agency and Element 21 Golf Company, based in Toronto, Canada. In the plan, the station's next crew members, due to launch to the station on 29 March, will try for the record-breaking swing during one of three planned spacewalks by September 2006.

A gold-plated, six-iron golf club will be used to hit the ball, which is made out of the same scandium alloy used to build the station. After being hit from a special platform alongside the station, the ball is expected to orbit Earth for about four years, beaming its location to Earth-bound computers using global positioning transmitters. Eventually, the ball will lose altitude through atmospheric drag and burn up in the atmosphere.
