Maybe they need to include Pluto so everyone who gets both messages will recognize it's the same spammer that keeps bothering them with infomercials.

This story moves me slightly.

London has been that way for years.

Well, yes, but those are Chicago's cameras in London.
I read that Chicago's camera network is everywhere.

I thought that the Battlezone which Franklin was talking about involved fighting kites.

If the duck is blue,
it's not for you.

No, they created a machine which ignores them. They're getting no response, so they know that they succeeded.

7 pages of comments and Slashdot readers haven't mentioned " Science: "2012" a Miscalculation; Actual Calendar Ends 2220". Yeah, there will be panic.

Build an industrial-scale mass spectrometer. Dump in trash, concrete, and rock. Frequently empty the buckets that the fissionables land in.

Copyright doesn't expire in 35 years. Granting the copyright is expiring, so the artists get the copyright back for the remainder of the copyright term.

There are several methods.

1. Smash coin with mouse. If coin bends, it is fake.
2. Put mouse on balance scale. See how many coins are required to balance the scale. If the number of coins is different from the number of genuine coins required, at least one fake has been detected.
3. Use the coin to pry the mouse apart. Look for scratches exposing a different color on the coin.
4. Put the coin on the mouse. Burn the mouse. See if the coin melts.
5. Put the coin on the mouse. Pour on the coin an acid which does not affect a genuine coin. Check if the coin survived.
6. Line up coins the length of the mouse. See if the number of coins matches the number of genuine coins.
7. Use coins to buy a mouse. See if the cashier rejects any coins.
8. Use coins to pay for a call to the Secret Service. Report that someone might have used a counterfeit coin to pay for a phone call from this phone booth. Leave the mouse in the phone booth. Repeat until the "mouse counterfeiter" or the "mouse crank caller" is caught.

Ever hear of an estate? Where the assets, such as copyright grants, have value which the deceased's will can direct to benefit the surviving family members? So a hard-working artist who dies too young can still take care of his family?

Their work isn't in the public domain unless they're federal employees or their local laws place their work in the public domain. But it would be better for the educational system if more material were easily available. State legislators should place that work in the public domain so it can be easily reused, but encourage teachers to produce it. Teachers do get paid by the school to create lesson plans, but they should be able to sell or retype it into a marketable package on their own time. If there is a lot of public domain educational material, higher prices will be paid for it being organized or for new material.

Notice, however, that this only applies to material created as part of their job. Work created outside of the job environment still belongs to the teacher. School contracts might have to be more specific about the definition of school work. A teacher can mix their own protected work into a collection and sell the package, just as book authors do now. There is no requirement that the specific public domain material be identified; if buyers prefer that PD work be identified then they'll only buy such material.
