We're flying to Oakland next week for a whole slew of events with family. I haven't decided if I'm going to opt-out of the advanced imaging scanners (AIS) or not. The TSA and FDA claim the X-ray backscatter imaging machines are safe, however they reference studies looking at a different energy-band of X-rays than are used in the machines. The millimeter-wave machines are likely safer. My decision may depend on which type of machine they're using (if Denver has them yet, they didn't the last time I was there) and how much time we have before the flight.

I am a firm believer that most of what the TSA does is "security theater," wherein they do things that appear to make us safer by responding to specific threats, but it does not (and can not ever) address all the different attack vectors terrorists might use. In particular, the AIS machines and the "enhanced" pat-downs (more like "feel-ups"), which have been introduced ostensibly in response to the "underwear bomber" from a year ago, fail to address "internally" stored explosives, so to speak. Not that I'm hoping for it to happen, but as soon as this fairly obvious attack vector is tried, what will the TSA do then?

I have some ideas.

• Have passengers to disrobe into hospital-style gowns with open backs. Then they must perform ten deep squats in view of a TSA agent. They have the option of visiting the bathroom beforehand to prevent "accidents" (or get rid of the evidence). This will have the side-benefit of preventing obese and disabled passengers from flying, allowing the airlines to reduce seat and aisle width and legroom even further.
• Tell passengers to show up to the airport six hours early and give everyone a strong laxative. This may be combined with the above, in order to "facilitate" the discovery or disposal of explosives.
• Sedate passengers prior and during to each flight period, giving them a 24 hour window over which the flight may occur. This prevents the terrorists from being conscious to set a bomb off, or set a timer beforehand. To prevent the use of air pressure-sensitive triggers, the sedated passengers would spend time in a high-altitude chamber.
• Good ol' fashioned cavity searches. Anything for security, right?

Sure, the things above sound ridiculous, but so does wasteful security that responds to specific threats, which is what we have now.

The River, by Bruce Springsteen, is a double album that reached the number one spot 30 years ago this week. Springsteen is one of my favorites, he ranks first in my list of number of plays on Last.fm.

I can't say that this is one of my favorite Springsteen albums, but I don't dislike it. It's the beginning of the path to Nebraska, an album I definitely have to be in the right mood to listen to. I think that's why this album isn't quite what I normally want out of Springsteen. I generally want upbeat, rocking songs out of Springsteen, and this only partially delivers. But, I'm comparing Springsteen with Springsteen, and all Springsteen in my opinion is better than most contemporary popular music (e.g. recent Black Eyed Peas). Which is to say that, this album should be listened to, unless, of course, you have bad taste in music and actually like current popular music (e.g. Justin Bieber).

This week I listened to Queen's "The Game", which was in second place behind Barbra Streisand's "Guilty" this week. This album has two genuinely big hits on it that still get plenty of airplay: Another One Bites The Dust and Crazy Little Thing Called Love.

One of the songs I like is "Don't Try Suicide" which is simultaneously macabre and sarcastic. Well, actually, it isn't a great song or tune, but I like the idea of a ridiculous song about something so serious. In this way it's similar to "Suicide is Painless" from the M*A*S*H movie and TV show (although the words are missing in the TV show). "Sail Away Sweet Sister" is a harbinger for the future of hair metal power ballads in the 80s. The number one hits mentioned above are still fun, if a bit over-played, still, 30 years later.

Today was my first official day of my postdoc position. Naturally, like most people would, I skipped out early to go ride my bike. It makes more sense once you know that for the last month and a half, I haven't gone for a bike ride because I haven't had health insurance. Not being insured made bike riding a risky proposition. As a result, I've also been walking to school and back which takes 40+ minutes each way, in comparison to the 10 minutes it takes on a bike. Today was my first opportunity to ride my bike, and it was sunny and relatively warm, so I wasn't going to pass it up. In addition, I've basically been doing this job for over a month already, so the first-day impression came long ago.

Today's ride was a bit of exploration, and very autumnal, as the photo above proves. If you look carefully, you can see some snow on the highest peaks. It was also my first opportunity to use my new Garmin Edge 705, which was a graduation present from various Ruggles. My legs definitely exhibited the effects of no bike riding -; they got tired very quickly.

Finally, happy November!

I've decided to begin listening to the number one album from 30 years ago each week and then write a little bit about it here. Why isn't terribly important, other than it will hopefully be mostly entertaining, always enlightening, and occasionally fruitful. However, here are a few reasons. I recently had my 31st birthday, and birthdays are always opportunities to ponder the passage of time. Presumably, I should have then decided to look back 31 years, but that makes the math harder (and thinking hurts) so I'll keep it at 30 years. Looking at the current top list of albums, much of it is stuff I definitely wouldn't listen to on my own volition. I doubt that in 30 years it will be judged to be any higher quality. In this sense, I could do this exercise with current music. But by going back in time I'm, exposing myself to new music that isn't currently on the radio (for the most part), so it has extra novelty. I already know the general direction of popular music over the last 30 years, so it will be interesting to see the progression in more detail with this foreknowledge.

I haven't fully fleshed out the rules of this. For example, if an album is number one for more than one week, I think I'll drop down to the second place album, or beyond. There will be other rules about if I've already listened to an album (for example if it oscillates up and down from number one).

This week I listened to Barbra Streisand - Guilty. The fact that this is the first album in this experiment made it very difficult to begin. I was not a fan of her work, and my opinion hasn't been improved.

First some observations about this album. The cover shows Barbra with Barry Gibb, of the Bee Gees. They sing duets on two of the nine of the tracks, which seems to be an awfully low ratio for him to be featured on the cover^*. Also, he doesn't really sing in his trademarked joyful falsetto, which is more false advertising. To me, that's 100% of his appeal, so without it, who cares? Furthermore, I'm not clear what anyone is guilty of in this album, besides being boring and uninspiring.

A few of songs have enough to them that the could serve as adequate background music during a Roger Moore Bond film, but certainly not during the introduction to a Bond movie. Most songs are Celine Dion-esque and are about strong women looking for love, but probably only appeal to women that are nothing like that. I'm missing the genetics and personality to appreciate it.

I'm planning on at least making a real effort to see this idea through for a while, but this is an inauspicious beginning.

(* Ok, apparently Barry Gibb wrote all of the songs, so his contribution is greater than 2/9ths.)

It's show-and-tell time! Below are two movies I made using the volume rendering tools of yt. I've been using yt for a few years to analyze and visualize the cosmological simulations I make with Enzo, and only recently have I had time to begin to play with the new volume rendering stuff.

The first movie is a slow rotation around the entire volume of a simulation at a contemporary epoch, which means that this image is produced from the state of simulation at its end, 13 billion years after it started. The colors correspond to the density of matter in the volume, from dark blue to white as density increases. The simulation is a periodic cube with dimensions 20 Mpc/h on a side. In comparison, the diameter of our galaxy is somewhere around one thousand times smaller. This means that the whitest areas correspond to clusters of galaxies, and our galaxy would be just a small part of one of the white blobs. Be sure to watch the movie full screen!

Below shows the time evolution of the simulation from beginning to end. This is a thin slab of the center of the simulation (10% thickness) viewed from a corner of the cube. Notice that early on the matter is very clumpy everywhere, but rapidly forms dense knots connected by thin filaments. This is how the real universe looks! After about the half-way point of the movie you'll notice that not much happens. Again, this is how the real universe looks! Much of the large-scale evolution of the universe was finished about 7 billion years ago. This movie uses comoving coordinates, that compensate for the expansion of the universe. If I were to use proper coordinates, which are the kind we use every day to measure normal things with rulers, the movie would show the simulation starting very small and then blowing up. Again, use the full screen option for the best image.

Yesterday I hiked in Eldorado Canyon State Park with Melissa, Megan and Megan's significant other Chris. This park is just south of Boulder and like much of the front range offers spectacular views. This time of year the trees are well into changing color and dropping leaves. The occasion warranting a hike is that today is my birthday, and since I am all done with graduate school, I have free time to do this sort of thing.

I saw this on my walk to school this morning. I don't know if the scoop is operational, or if the exhaust really runs through the pipe below the door. The color isn't doing it any favors. I do like the white-wall tires, which are a nice and subtle touch (but they could use a wash).

I'm back in San Diego for the next week and a half in order to graduate. I defend in one week on the 27th. The photo above is of a tarantula that lives in the office that I used to sit in, and that I am sitting in again while I'm here. That is its full significance to this post.

If the tarantula isn't big enough above, you can make it bigger by clicking on the image!

Today I rode "Super Walker" which means that I did the Walker Ranch loop starting from town rather than the trail head. It turns out that the ride really is super, and there is a huge amount of climbing. Over 5000 feet of climbing in 30 miles.

I am going to brag again about how amazing cycling is here, and show some more photos of some of the ride today. You may click on them to enlarge them. Below is South Boulder Creek, which a couple parts of the loop crosses and parallels. The water was moving at a good clip!

A view looking North-West from one of the ridge lines the trail follows.

This is looking roughly East, down into the plains South of Boulder in front of the mountains.

Often times, the warning signs along trails are overly-cautious. It's not that I think they don't apply to me, but once I've ridden a trail a few times, I can judge for myself how technical the trail is, or how fast to take a corner. As long as there is no one else on the trail, and I can see far enough forward to be safe, I go my own speed. On this trail, however, I do not have experience, so I decided to heed the warning.

This is one case where the warning sign is correct. These are the stairs immediately after the sign that are significantly steeper, with bigger vertical step sizes, than most people find comfortable. It's always tough to tell how steep things are in photos, but trust me, there is no chance I'll ever ride these stairs. The stairs go down to the canyon floor which has been carved by South Boulder Creek, and is very steep and rocky (as can be seen) on both sides. But the scenery is fantastic, so the inconvenience of the stairs is worth it!

It has been nearly a month a half since my last post about leaving San Diego, and we've finally made it to Boulder! Ok, actually it didn't take that long. It took us two days, with a stop overnight in Saint George, Utah. The long gap in posting is due to how busy I've been here in Boulder, which has been nearly entirely due to getting my thesis done, but also to a good deal of work getting the new apartment put together. Those things deserve their own posts, which may or may not happen.

What I would like to post here are some pictures I took on my bike ride yesterday. I am 99.7% done with the draft of my thesis which I'm sending to my advisors this weekend, so I figured I could take some time to ride my bike recreationally. This is a novelty for me recently. Come wintertime, I'm definitely going to miss the weather in San Diego, but right now, cycling here definitely beats San Diego. It takes less than ten minutes to get out of town onto roads like this:

or this:

or this where it feels like I can see all the way to Kansas over the plains:

I just wanted to share. Hopefully, now that the bulk of the thesis is done, I can enjoy this area a bit before winter hits!

Today we're driving from San Diego to Boulder. The various mapping services give the drive time on the order of seventeen and a half hours. Most of our things have been picked up by the movers and we're only carrying the things we need, can't replace, or is alive. The movers were supposed to have come yesterday so we could leave yesterday, but there was armageddon traffic on I-5 so they delayed coming today. The apartment is empty and we've turned in our keys.

Not really how it looks in the middle of July, although it did drizzle this morning

I'm sad to leave San Diego, it has been a very good place to live for seven years. I'm leaving behinds lots of friends and a place I'm used to living with weather I like. Boulder is an exciting new place with new friends to make. It has four seasons, which will be a new thing for both of us. I don't know if we'll ever live in San Diego again, but I do want to come back and see my old friends and go for a bike ride with them.

Goodbye!

I've posted the 2010 Tour Pool results page. I did absolutely no research for my team, and I'll probably do just as well as all the other years I've participated. I have a few more sprinters than normal this time, so hopefully I'll get some more bonus time than what I usually get, which is very little.

For this year I bought a pass so I can watch the Tour online, live or time shifted after the daily stage is over, for something like $30. I feel that this is entirely appropriate because it jibes with my issues with subscription television. There are several channels on Cable/Satellite that I would like to have (Comedy Central, old SciFi (not the SyFy it has turned into), Versus, Discovery...), but the large majority I can do without. The media companies make it impossible to pick and choose the channels in an a-la-carte fashion, so I choose to have no subscription TV at all. Paying for this specific event just once, rather than month over month, allows me to view what I want, where I want, and it saves me money.

Oh, and I think Contador will win this year, and Lance will be top five.

Last Thanksgiving I attempted to do a ride I have had in mind for a long time. There are four regional parks near to me, Peñasquitos, Sycamore Canyon, Mission Trails, and Marion Bear, that I have mountain biked in over the last few years. It occurred to me some time ago that I could make a loop of them and ride all four in one day. My attempt in November was unsuccessful - my route through Mission Trails was ill-chosen and it nearly killed me (OK, not really, but it was pretty awful). I decided to go directly home, skipping Marion Bear, and finished with only three of the four.

Today I, and my friend Stephen, accomplished the four-park ride. Most of the time and distance was off-road, although there is the inevitable on-road connecting sections. There were no crashes, although I nearly endoed at one point, and one pedal broke (his). Luckily it wasn't too hot out in Sycamore Canyon. I'm tired, of course, but happy that I finally accomplished it.

This was taken on Flagstaff Rd above Boulder looking to the East.
