A few days ago while I was still in the Bay Area, I visited the new Academy of Sciences museum with my family. They just re-opened a few months ago after replacing their old earthquake-damaged buildings with a new, very unique building. You can follow those links to learn all about the "living roof" and the various exhibits.

I have some mixed feelings about the new museum. The old museum was a funky amalgamation of several buildings built over many decades. You could see the history of modern American natural museums in one place. The old section had dioramas of taxidermied animals in pseudo-natural scenes. Exhibits like lions hunting antelopes with Serengeti sounds playing on speakers. The newer sections had live animals and fish and a greater focus on education. The whole place was labyrinthine and dusty, and a well-used kind of ancient. It was never too full of people. I liked the old museum and I'm sad that a piece of my childhood is gone.

The new place is very shiny, flashy and popular. We waited for one hour and forty minutes to get inside. It might be bigger in cubic meters due to the higher ceilings, but I don't think it's bigger in square meters of floorspace. The main exhibition areas are limited to the two ends of the building, past the planetarium and tropical sphere, and the aquarium has been moved to the basement. The aquarium is quite a bit nicer than it was, with a few tanks that rival the Monterey Bay Aquarium in quality and cool curving Plexiglas, but not in size. Like the Monterey Bay Aquarium, the museum pushes education on choices the individual can make to positively change their effect on the ecosphere. They have a "carbon balance", but it mostly ends up being played with by children who generally don't decide whether to buy a SUV or a hybrid car.

I found a couple things I really liked; click on the thumbnails above. Read the tag on the human skull, and take a look at a whole wall of very carefully pinned ladybugs. I took three pictures a various zooms. That may have been a PhD thesis, right there.

Yesterday, Melissa and I visited the Monterey Bay Aquarium. We were met there by my brother Adam and his lady friend Shinji, who not coincidentally decided to also see the aquarium on the same day. The aquarium has expanded since my last visit. There is now a northern wing that has fresh water otters, an "outer bay" tank and a seahorse exhibit (that was under construction, sadly). More than the last time I was there (or maybe I was too young to pay attention to things not cute), the aquarium really pushes conservation and ethical seafood consumption. They have a [set of cards](https://www.seafoodwatch.org) you can carry to help guide seafood and sushi purchases in stores and restaurants.

The Hearst Castle is ridiculous. The architecture and the history of the people who visited it are quite a spectacle. And of course I think it would have been grand fun to have visited it when William Randolph Hearst was alive and the place was hip and hopping. I was wondering with Melissa over dinner if I became silly rich could I invite movie stars and political leaders over to my remote ranch? Probably not. We did both agree that if we were to build on that site we would have had more of the buildings and common areas facing the grand view. As it is, many of the rooms, like the dining room, have no view.

Before we went to the castle we looked at some tide pools. Melissa even found a hermit crab wandering in between the rocks.

Tomorrow we will see the Monterey Bay Aquarium.

Melissa and I are taking the slow route up to the Bay Area for the holidays. Tonight we're staying in Santa Barbara, and we'll visit the Hearst Castle tomorrow. For dinner we ate at a decent Mexican restaurant on State Street. Afterwards we walked down State Street looking at all the shops and restaurants. It's clear that the economy has started to hit Main, err... State Street America. Despite the Christmas decorations, and the huge tree in a left-turn lane, there are quite a few empty stores and others going out of business. I guess now is the time to start a new business cheaply in Santa Barbara - as long as you can weather the current economic storm.

More tomorrow!

It's been really rainy and a bit cold here in San Diego so far this week. Here are some pictures I took today of the rain, and a couple of our xmas decorations.

Yes, that's a bike work stand in the foreground.

Below is the map showing the just-released 2009 Tour of California stage 8 route. And I'm disappointed. I thought the stage would end on the top of Palomar Mountain, but it is simply going to pass over the top, circle back around and finish in relatively boring Escondito.

Just like when the race goes through the Bay Area, I am familiar with much of this route. The race starts in Rancho Bernardo, and heads east on Highland Valley Road. That road has several nicely steep sections that kick my non-professional racer butt. I'm sure that the pros won't charge up those hills so early in the race, but their pace would drop me, no doubt.

They go up the hard side of Palomar which is a world-class climb. It is every bit as hard as the Tour de France cols I've climbed. In February the top of Palomar can be quite cold (sometimes it even snows) so the temperature changes along the route could have an effect on the race.

I wish the race organizers would have given us the grand spectacle of a mountain-top finish. I am grateful, however, that they've finally dipped below the Los Angeles divide.

Oh, and I can't forget to note: parts of the race go through Indian reservations, so the racers can get their gamblin' on, if they feel like it.

Here are some photos from Corvallis. There aren't any truly spectacular photos, but the fall colors in town and on campus were nice.

The outcome of the Cal/Oregon State game was disappointing, as you can see on our faces.

Everything in Corvallis and on campus is beaver-themed; he jumbotron in Reser stadium is called the "Dam Cam."

On Sunday Matt, Tona, Jenny and I walked around campus.

Campus is quite nice with many brick buildings and leafy tree-rimmed quads. The weather was great on game day, but cold and overcast on Sunday.

The Bears lost to the Beavers today. Another season of mediocrity for the Bears is confirmed.

I attached the GPS to the window on the plane from Oakland to Portland. Check out the speed (it's in M.P.H.)!

As a computational astrophysicist, I can work pretty much wherever there is an internet connection (except the San Diego public library, but that's another story), so at least a day or two a week I work from home. And when I do, I have a little work buddy who sits by my chair waiting for me to throw a foam ball across the apartment so she can fetch it (seriously!). I try to ignore her so I can get work done, but as soon as I even look at her:

She's cuter than my work buddies at school, of course.

UC Berkeley has bear statues, UCLA has their bruin statue, UC Irvine even has an anteater. Now UC San Diego has a Triton!

As I walked to lunch I saw the unveiling ceremony ending while the UCSD band (we have a band?) played the UCSD fight song (we have a fight song?). Below the statue there is a few streams of bubbly water and a plaque which explains that the Triton doesn't get to use his awesome trident, he just blows really hard on his conch which scares all the other gods and baddies away.

I, for one, am now waiting for the UC Santa Cruz banana slug statue.

My adviser Professor Mike Norman, as part of his job at the San Diego Supercomputer Center, purchased an optiportal system for the new SDSC building which is opening today. An optiportal system is a wall of monitors powered by networked computers such that the screens behave as one monitor. Very high resolution images and movies can be tiled across the screens, as you can see below. Movies and animations can also be tiled across the screens.

My labmates and I (Rick Wagner in particular) spent the last week feverishly building the system. The primary work was to build the monitor rack. It has many bolts and sliders and adjustments. We arranged to have two holes drilled through the wall for the monitor cables. The 30-inch screens require a very particular kind of cable and getting enough of the right kind that were long enough to reach all the screens was surprisingly difficult.

My main task was to convert some of the publicly available high-resolution astronomical images into tiled TIFFs. Tiled TIFFs break the data up into easy to scale tiles, which is essential for the optiportal. I used many of the images from this page (link broken), including the 403 megapixel Carina Nebula image linked there. It was quite frustrating. I tried half a dozen computers and iterations of ImageMagick and VIPS before I finally got a combination that worked.

In some ways, this is worse than a projector. There are gaps between the screens. This requires multiple expensive computers and many, many cables. However, there are some big advantages to this setup. There is no projector that has anywhere the same resolution as this optiportal (2560x1600x20 = 81.92 megapixels). Just one of the monitors is better than all but the most specialized and expensive projectors. The screens are bright and clear, even in normal lighting conditions. Unlike a projector, standing in front of the screen doesn't shadow the image. It has to be seen for yourself; twenty 30-inch monitors are awesome to behold.

Each four-monitor column is powered by a HP xw8600 workstation with one 4-core 2.33GHz Xeon processor, 4GB of RAM, two NVIDIA Quadro FX4600 768MB video cards with dual output, running Ubuntu 8.04 LTS. There is a sixth identical workstation that serves as a head node which sits in front of the screens and controls the output on the wall. There is also a HP ML370 server that has a 1TB RAID5 disk array, and has room for an additional 1TB. Eventually, all the machines will be connected by a 10Gb CX-4 network using a ProCurve 6400cl-6XG switch, and the head node and disk server will be connected to the outside world with a 10Gb optical connection. The monitor array is controlled using CGLX which is developed at Calit2, which is here at UCSD.

Science will not be performed on the optiportal, at least the major calculations won't. Instead, visualizations of simulations run on supercomputers will be displayed and analyzed. The human eye and brain is still a superior judge of the accuracy and meaning of data than a set of conditional equations. It is often necessary to actually see the raw data as clearly as possible. The point of the eventual 10Gb optical connection is that various parallel visualization programs like VisIt and ParaView will be practical. These programs do the data analysis on a remote supercomputer and the visualization is sent to the optiportal in real time for display. In this way, terabytes of raw data don't have to be transferred off the supercomputer, and the computationally intensive part of the visualization takes place on the supercomputer, which has far more processors, RAM and disk space than the optiportal. I hope to someday have some of my data displayed in this fashion.

Above is a graph showing my net worth since January 2007. I have removed the actual dollar values for the bars because I'm ashamed of how poor I am. Or wealthy I am. I'm not telling. But remember that I'm a grad student, not a former CEO of a failed investment bank - you get the idea.

I've put two numbers in orange on the graph. If in my richest half month I had one dollar, now I have 68 cents. Put another way, I'm now about two-thirds of my former self, and this took five months. The graph above includes my cash accounts, which haven't gone down, so my investments have declined even more than a third. Luckily, I don't need that money any time soon (I have to graduate before that), but it's a bit depressing.

It's also an opportunity to buy some really cheap bank stocks and hold them until they recover. Which would more or less cancel out the inevitable tax increases my generation will have to pay to bail out our selfish parents.

At least I can say that I'm ahead of the curve on the grad school thing.

My beard experiment has ended. As part of the journey, I did an experimental time lapse, above. As you will see, I slowly shaved my beard and rotated the chair. I should have thought more about exposure consistency between frames. Doing it inside would have worked better but I thought the outside view was more interesting.

I admit that a few hours later I am still occasionally reaching up to stroke my beard, and finding nothing there.

I took a break when my mustache was in full flight and posed with Melissa. As you can tell by her expression, she loved the `stache.

Two days ago Melissa and I drove from Berkeley to San Diego. We drove on US 101 for most of the way, but used Hwy 1 between Monterey and San Luis Obispo. The weather was fantastic and the scenery beats I-5 any day, even on 101. It does take longer, but it's worth it if you don't have arrive at the destination at any particular time. I wanted to record the journey, as I have before, but this time looking forward. Using the Canon A620 my father gave me and my laptop connected to it using USB, I managed to do this without too much interference. However, the batteries on the camera died early on, so I didn't capture the whole trip, or even the most scenic parts of it. In the future I'll need to use an external power source.

I am sharing it because there's no harm. It's not very good, so I didn't bother to add any music.

The video lasts 1 minute 44 seconds, is 5.6 MB in size, and the frames are separated by eight seconds.
