    One of my pet peeves: "Less" vs. "Fewer".

    You're on the losing side of that language change. Too many people are being taught math these days, and mathematical terminology pretty much uses "less [than]" for all numeric comparisons, regardless of the English count/mass classification. The math world simply isn't going to listen to this particular peeve, and will continue to teach people to use "less" for any numerical comparison.

    Actually, if you dig into the history of the topic, you'll find that "less" has been used this way pretty much since the language has been called "English". The less/fewer distinction is a bogus modern peeve, invented by people wanting to impose a distinction that the language has never made.

    We shouldn't have a federally owned ISP. In fact the government shouldn't be in the ISP business. They should be in the infrastructure business and that should be done at the city/county level and always should have been.

    Actually, we have in effect had that for more than a century. "The government" owns and controls all access to the basic, low-level part of the communication infrastructure. Specifically, the right-of-ways for wiring and the frequency bands for wireless are and always have been owned by governments, which leases access to the private comm companies.

    Of course, we've seen the problem with that: The government in control of the right-of-way in most jurisdictions makes a deal with a single comm company, and outlaws access by anyone else. Sometimes they make a deal (usually the same deal) with two companies, so they can claim that it's not a monopoly, which satisfies enough people and the duopoly can behave exactly like the monopolies in other areas.

    If we really want a communications "market", we need more than a government that controls the infrastructure and leases it out. We need a government that supports a comm market, and leases out the infrastructure to everyone.

    The closest we've come to this is with the FCC, which has historically opened up a few small parts of the spectrum (ham, cell-phone, wifi, etc) to the general public. But even they keep most of the spectrum locked up and available only to a very few corporations.

Funny thing is that I used to live in Madison, which has long been around 90% a university and government town, so you'd think people there would be familiar with the constitution. But asking 112 (unidentified) people to sign it got 111 refusals, mostly out of fear that "it was some kind of subversive document and thought that if they signed it they would be called Communists."

Hardly anyone anywhere actually recognized the text.

Read the tiny language that comes with most such contests, and see if you can spot where it says this.

    I've seen a couple of writing contests run by publishers that play the same trick. The top-rated 2 or 3 stories get a reward, but the publisher publishes an entire book of the top N stories.

  13. Is this a precedent for online music? on Author Drops Copyright Case Against Scribd Filter · · Score: 1

    This could be a useful precedent for the music business. A growing problem is: You're a musician who thinks you've written a new tune, but think you might be pulling a George Harrison and merely putting new words to someone else's tune. How do you find out if the tune in your head is copyrighted?

    Some significant work has been done with putting music online in several computer-encoded forms, with several lookup tools that try to identify similar pieces of music. Leaving aside the fact that this is a nontrivial problem musically, the work has been seriously held back by fears of the copyright enforcers. There have been demands from publishers and agents that copyrighted music be removed from the databases, which has usually been done. So the available music is pretty much just material that's out of copyright. It's obvious that you can put Bach's and Beethoven's music online in computerized form, and it's equally obvious that "folk" tunes published centuries ago (by Playford et al) is legal.

    But I've actually asked some music publishers' reps how one might legally find out if they hold a copyright for a particular tune. Their answer, apparently told with a straight face, is that I should buy a copy of everything they've ever published, and search through all of it for the tune. There is a certain lack of practicality to the idea that every musician should own a printed copy of every piece of music that's under copyright. I'd need a house orders of magnitude larger than my current house to hold it all. And the search operation would take several years of full-time work.

    So what's the prospect for this decision being applicable to music? Would it be legal for musicians to transcribe lots of copyrighted tunes, putting what's essentially a computerized "fake-book" version of everything in our database, and make the lookup tools available online to musicians? Or would we be risking a multi-million-dollar years-long lawsuit over such a tool? Asking publishers for permission isn't feasible; many of them have already said they don't approve.

    If it's not legal, how might a musician learn whether that tune in their head is copyrighted? You can play it at a gig, and wait for the indictment papers to arrive at your door, of course, but it'd be nice if there were some better way that's legal. It'd be even nicer if the database could have contact info for each work, so the musicians can quickly ask for permission to play a work in public. But at present, such a tool seems illegal, on the ground that its database is inherently a mass of copyright infringements.

    (There's also the separate problem: How to decide whether two tunes or songs are "the same music" is an unsolved problem, whose only answer right now is "Ask the courts", and it's not obvious how to write a CGI program that does that. ;-)

Second, lawyers quickly pointed out that under that interpretation, George Washington couldn't have been president, since he was born before there was a United States.

Mathematics is about logic and reasoning, not physical objects. In even the oldest and most basic fields of math, this is fairly clear. Try finding a number in the real world.

The difficulty is based on the fact (;-) that nobody seems to be able to find physical objects in the real world that exactly satisfy any mathematical definitions or axioms.
