I completely agree. Scientific publication is an immense racket at present. We pay to submit our articles, review other scientist’s articles for free, and then still get charged to access our own publications and are forbidden from posting them where they're publicly available.
Unfortunately, I think it will still take another generation to "get out from under the thumb of the publishing houses" and move to an open-access model.
The prestige of a publication in Science or Nature is an immense boost to your career. What journal your research gets published in is a very decisive factor in getting a tenure-track position and in getting tenure.
That's why what Princeton is doing is such a great thing. It allows you to still submit and be published in a prestigious journal, but hide behind the university's legal team when it comes to posting your publication where everyone can access it. Google scholar does an amazing job of finding publicly available copies of scientific publications on a researcher's personal website, etc, so this is a big step towards open-access scientific publication without having to sacrifice your career.
Denyhosts isn't security through obscurity in any way.
It just monitors
I think you're thinking of port knocking, which is security though obscurity, though it's still damned useful.
While they're at it, it would be awesome to deploy a few more seismometers...
Moonquakes are pretty damn cool from a seismological perspective. Beyond that, some of the ones recorded by Apollo-installed seismometers were >Mw 5. Big enough to be damaging.
The moon isn't tectonically active, of course, but it is seismically active, and the data recorded in the 70's indicates that the moon's lithosphere is a very different beast compared to earth's. At any rate, it would produce some extremely neat data!
There's no income tax in TN, but there's a 9-10% sales tax on _everything_. That includes food and drugs. It's a horribly regressive tax.
If you're wealthy (or just upper middle class) you spend a far lower portion of your income on basic necessities like groceries. Most of your income goes towards untaxable (by the state, anyway) things such a savings, education, healthcare, goods bought online or out of state, lawyers fees, etc.
If you're not wealthy, most of your income is going toward necessities that are taxed at the full 9-10%.
In the end, the lowest income bracket in Tennessee pays ~3x the percentage of their income that the highest income bracket does in state taxes. Partly because of this, TN has the 3rd greatest income inequality in the US (gap between high and low earners).
At any rate, there are a lot of good things about Tennessee, but the lack of an income tax isn't one of them.
Kpdf/Okular is great if you're running KDE as your desktop. With kde4, I think okular will eventually be available for windows as well. (I'm not sure on that...) The main advantage is that it's very quick to load and tightly integrated with Kdesktop. If you don't use kde, it has fewer advantages over the others.
You can annotate and review pdfs in okular just like you do in acroread. It doesn't have editing capability, but neither do the free versions of almost anything else, to my knowledge. (PDFedit is an exception, but it's too clunky for day-to-day use as a reader.)
What the world *really* needs is a good Automatic Bicycle Sharpener.
