great argument for people to start using dover books as texts. (that's happened in two classes i took.) they're always expanding their catalog, and starting to publish books first printed in the 1970s and even the 1980s.
great. any finite time is less than forever. talk about a case for more rigorous mathematics education... and i'm only being partially facetious, here.
I don't think Ithaca--I went to college there--is a very good representation of all of upstate NY. (Even disregarding the fact that Ithaca is in central NY.)

more importantly, lack of good CLI interfaces means that it's much harder to get programmatic (is that a word?) access to your system's operations. simple example: i have a script which parses log files for ssh probes and then add the probing IPs to my iptables to block them. lots of admins hove much more complicated scripts to perform common repetitive tasks, or tasks which cull data from several places.

actually, local sources of GWs are highly unlikely to produce signals which are detectable. the bigger problem is local sources of vibration: trucks driving on the road, heating and air-conditioning fans, planes flying overhead, etc etc.
saulson's book has an example calculation of what would be needed to generate detectable GWs in the lab. take two steel balls, mass 1000 kg each, 1 meter apart. rotate them around their common center of mass at a frequency 96 Hz (about 600 rad/s). the strain that generates is about (1/r)*1e(-35) where "r" is the distance from the generator to the detector. in comparison, a typical pair of neutron stars, 1.4 solar masses each, 20 km apart, and rotating at about 400 Hz. if the pair is in the Virgo cluster, about 15 megaparsecs away, the strain at the earth would be about 1e(-21). this sort of order of magnitude stuff can't just be handwaved without a few approximate equations.
i did my phd research with ligo, so i have somewhat of an insider's view.
you can "filter" slow moving sources out: they are nearly static compared to the, say, 1kHz oscillations of a pulsar, and so the sun etc. are just a simple DC offset and don't really affect the sensitivity much. more tricky is the filtering of terrestrial sources of vibration.
your analogy is inaccurate. detecting change in the sea level is detecting a dc offset. to be more accurate, you can say we are trying to detect the waves from a pebble dropped in the ocean, trying to pick it out from all the other waves around. the actual situation isn't as bad as that, though.
my mistake, i meant "teTeX is a complete TeX bundle, including LaTeX".
so, LaTeX is really a bunch of TeX macros. anyway, teTeX includes both TeX and LaTeX since TeX is a prerequisite for LaTeX. it also includes all the utilities you expect: dvitops, dvitopdf, etc etc. it really is a complete TeX bundle.
if you use the commandline, i recommend the fink installation since i use it and it works well. if you want a GUI TeX editor, the other packages mentioned by others in this thread would probably work better.
I use the "unstable" fink tree. It has tetex-3.0 as of today. It works just fine: I wrote my dissertation with it with no troubles. See here: http://pdb.finkproject.org/pdb/package.php/tetex That link also shows that tetex-3.0 is available on the stable tree. Just do "fink install tetex" (or maybe "fink install bundle-tetex".

just right click and open the image in a new window/tab to view it at actual size. they're not bad, then.
And an explanation of negative index of refraction (with picture).
And a better article than the one linked.
Maybe it's not wall thickness but weight of the vessel. Or perhaps both, by which I mean density of the vessel.
then, along came find(1). who the hell wrote that? :)
your opinion is just a xerox of the others.
Vi? Pah! Ed is the one true way!
LaTeX? Luxury! I still use troff.
For OS X:

Like I said, Fink *does* have LaTeX, and has had it for more than 3 years.
What version of Fink are you using that it doesn't have LaTeX? I've been using LaTeX by way of Fink since I got my Powerbook more than 3 years ago.

teTeX is a complete bundled LaTeX installation: http://www.tug.org/teTeX/
There are GUI TeX environments for OS X, but I never bothered to learn them (like iTeXMac or something). See this: http://ii2.sourceforge.net/tex-index.html
latex support is "only slightly better in OS X"?
it's at least as good as support in linux, since you can compile (or use fink) teTeX and LyX.
but, it's better on OS X, i find, because i can use BibDesk.
