Zoom in on the Hawaiian archipelago; de-selecting multibeam bathymetry surveys and switching the base map to "Shaded Relief (GEBCO_08) will give you a nice image of what the chain looks like under water. Kaena Pt is the westermost tip of the island of Oahu. Also note that Maui Nui was once a much larger island, encompassing Maui, Molokai, Lanai and Kahoolawe. Loihi is visible to the the southeast of the island of Hawaii.
CFD simulation. Lattice Boltzmann simulations of fluid dynamics is one such application. Folks at the various DOE national laboratories have a pretty keen interest in this kind of simulation.
A pretty good summary of the sad story of the Yucca Mountain nuclear waste repository. I was briefly involved with that project in a past life when I worked for a defense contractor.
The MLO is located 34KM WNW from and well above the summit of Kilauea. The primary volcanic emissions plume from Kilauea is driven by trade winds which blow mostly from the NE, and because of the topography of the Big Island most of that plume will bypass the observatory. However, there has to be some effect from it; the question is how much?
FWIW, I live on the Kona side of the Big Island and get to enjoy the effects of Kilauea's vog (volcanic smog) more than would like.
Watches are still useful. I wear a watch from time to time -- I own 4. A dive watch from St Moritz - a Momentum M50; a low-key dress watch from Skagen; a Breitling Old Navitimer; and my grandfather's Breitling Montbrilliant pocket watch. The latter two don't get out of the safe much any more.
I am going to assume that was Mauna Kea and not Mauna Loa. There is a road to the summit of the former, paved part of the way, for the people who work at the observatories up there. There is a 4WD unpaved "road" part way up the slope of Mauna Loa but no vehicular access to the summit.
Rental car companies don't like having to come collect their vehicles from Mauna Kea after people have destroyed the brakes in them riding them all the way down the hill (or having negative interactions with invisible cows at lower elevations).
FWIW when I make trips to the summit I bring oxygen, and spend an hour or so at the Visitor Information Station at 9300 feet before heading up to the summit.
Working at altitude can be deceptively difficult -- an acquaintance who works at the summit describes a conversation he had which went something along the lines of "Well, I've cut it three times and it's still too short". Low PO2 isn't good for higher cognitive function.
No waiting - choice of paper or electronic. Most people opting for paper (as I did). Process was pretty painless; in addition to the federal election there are some choices for local stuff: state senator and representative, trustees for the Office of Hawaiian Affairs, county mayor and prosecuting attorney; some proposed state constitutional amendments and several Hawaii County charter amendments.
One of my regrets is never seeing an SR-71 in the air
I worked at UCSD in the mid 80s; the building I worked in was pretty much directly west of the runways at
NAS Miramar (now MCAS Miramar). In 1987 (1988?) the annual airshow there had an SR-71 come in for a
visit. We watched it make a couple of lazy spirals as it came in for a landing at the base a day before the
show.
At the show it was shown in static display surrounded by armed Marines. Awesome aircraft.
Actually 120M is closer to 400 feet (393.7, to be exact). It would need to be deep to completely submerge it. To make it a reasonable wreck dive it would need to be in water deep enough that it posed no navigation hazard. Something the size of this ship would need very deep water to ensure that the shallowest part was, say, 20M from the surface. That would make the bottom somewhere near 135M (450 feet), assuming it sunk upright. From a technical diver's perspective this is beyond the reach of all but the most elite. Too bad, it would be an interesting wreck dive if sunk shallower than that.
If you have the "wreck bug" - go visit Truk Lagoon. Seriously some of the best diving I've ever done. While you can benefit from advanced training (mixed gas, wreck penetration/overhead environements) it's not necessary to enjoy the majority of the wrecks there. Many of them are completely encrusted with life and start at shallow enough depths that much can be seen even with a single 80. It's a long trip from most places (even here in Hawaii), but it's simply amazing wreck diving.
Yes, I have tried LED lights. I use them as backup lights for underwater
(SCUBA) use.
While my primary light is HID, and I vastly prefer its color
profile, the LED light offers long burn times (battery life), which is just
what you want for a backup light.
Additionally, Luxeon Star (http://www.luxeonstar.com/) LEDs and
improvements in reflectors are making LED lights more useful as primary
lights as well. My wife carries a 4 watt Luxeon Star light as her primary light
(in addition to her camera).

So you get paid to go cave diving? Nice!

Next thing you know, Hitatchi will make some kind of 'magic wand' security can wave ..
Hitachi does in fact make a 'magic wand', but I doubt that the security folks would be waving it at you

Nice work tracking that one down. It must have been very frustrating - what we used to call a "ring-tailed b1tch"

Actually, the quote is from Igor Stravinsky. See http://en.wikiquote.org/wiki/Igor_Stravinsky
Some of the Dolphin Huggers(tm) (http://www.joanocean.com/ http://www.etfriends.com/)
out here in Hawaii believe so; they won't tell me where they are, though (and I'm a trimix diver!)

Odd. I've been a user of FreeBSD from 2.2; the 4.9 -> 5.3 transition was more or less painless for me.
Indeed. I've been thru two acqisitions, one by Cisco and one by Nokia. They both used to be on top of the world. Not any longer.
Most of us have moved on to other things. Quite a few of the old crowd are still in the Santa Cruz area, though.
While I agree about fusion research being the most important, for fission here's always breeder reactor technology.
