Seen going past our front door twice yesterday, a man cross country skiing pulling two little girls in a sled. Snow and lemonade, I guess.

For our trip to the Bay Area for Thanksgiving, we took the Amtrak California Zephyr from Denver to Emeryville. The train leaves Denver at 8am, and arrives in Emeryville at 4:30pm the next day. It's clearly not the fastest way to travel (nor is it the cheapest with a sleeper cabin, which we purchased), but it is far more scenic than the alternatives.

Real utensils! Lovely and unique railroad views!

The train consisted of (in order) two engines, a baggage car, three coach cars, an observation/lounge/snack bar car, a dining car, and two sleeper cars. Our cabin was in the last car. Included in the price of a sleeper cabin are all meals in the dining car. The food is better than airline food (well, that is, was, when meals were actually a thing that airlines did) because it's actually prepared in the kitchen below the dining room and not simply microwaved. The dining car has tables that seat four, and if your party is less than four people, you will be seated with strangers. We met some interesting (using the full breadth of that word) people while eating our meals.

Our "roomette" was cozy. There are four shared toilets in a sleeper car, and one shared shower. The toilets are pretty much like airplane lavatories, but the shower was surprisingly spacious, fairly clean, and the water pressure and temperature was good.

The Zephyr is considerably quieter than a passenger jet, but because it runs on rails that are used primarily by freight trains, the ride isn't always smooth. It was not such an issue when the train was moving at 30 or 40 MPH through the mountains, but when it was going 80 MPH across Nevada in the middle of the night, it made sleeping difficult.

In summary, we're glad that we took the train. It's a unique experience that goes through the most beautiful parts of America that can't be seen from the interstates. We had the time to do it, and it was worthwhile. That being said, we're not eager to do it again anytime soon. We met many people on the train who seemed to love it - they were even on a first-name basis with the train staff. But the train isn't quite for us. Still, we recommend that other people consider trying it at least once. There are many things worth doing at least once, and this is one of them.

On a whim I did this time lapse out our front window yesterday. I didn't plan it out very well and I shot it through the half of the window with a screen, but it turned out ok, I think. Look for the tree branches springing upwards as they lose snow, car tire tracks evaporating, and the shadows and clouds moving as time progresses. The frames are separated by about 1 minute for the most part, but I was adjusting the interval in the beginning so not all frames are separated by the same amount of time. For the best effect, make sure the "HD" option is turned on and the video is viewed in full screen. It's 1m20s long.

The recent snow is very moist and sticky, and since it's still fall, many trees still had their leaves. This caused lots of broken branches, including some that fell on our roof. We think none did any damage, but this one hanging over our front door presented another danger this morning - it hosted icicles directly over our front steps. You can see that our steps are iced over as well. Since I took the photo I have knocked down the icicles and scraped and salted the ice on the steps.

I received a request for more photos of Boulder Creek in October.

Fall has hit the Front Range, and the Aspen trees are showing it. I took these photos on my bike ride today, and I could have taken dozens more, but I would have never made it back home! I wasn't the only one out there admiring the fall foliage - traffic was about as busy as I've ever seen it, and I saw many people pulled off to the sides of the roads taking pictures of the trees and views.

Since most of you cannot be like all the people I saw today and admire the views in person, here are some of the more spectacular views I felt were worth stopping for and sharing.

Riverside Drive past Raymond. This is one of my favorite roads in this area. It takes 2 hours to get to, and it's over 7500 feet in elevation, but it looks like this the whole way.

A panorama of Riverside Drive between Riverside and Raymond. Happily, even today the road had almost no traffic. Again, you should look at the full-sized version!

Last night I had the opportunity to tour the supercomputer recently built here at CU named "Janus" that I've been using. It is a 16,000-core Dell cluster using 6-core Intel processors running RedHat Linux. It was built in an interesting way. Instead of building a machine room in a building and then filling it with cooling ducts, pipes, and power connections, the machine room is made up of standard shipping containers that had all those connections in place, similar to a pre-fab house. These were shipped from the factory (in Canada, I think) on trucks, and then dropped next to each other in a parking lot behind a campus building. Unfortunately, because it was nighttime, I don't have a good picture of the outside.

Below are some pictures I took of Janus.

The machine racks. The door encloses the 'hot' side of the machines, where the air is sucked to the heat exchangers.

The cooling system.

The blinky and hot end of the machines. Lots of wires!

A close up of the back of a compute node. Notice that they have serial ports, which are based on a 40+ year old standard. At least they have USB ports, too.

It was using 415 kW of power. I think it can go much higher than that when the machine is under heavy load on a hot day.

I took this photo yesterday looking down above Jamestown. I took it with the HDR mode of my iPhone, and you can clearly see I did not keep the camera steady. Still, I think it's a cool picture, and the ghosting on the ridges is kind of interesting.

I've decided to modify how we back up our lappies at home. Instead of using SuperDuper! to back them up to individual external drives, I'm now backing them up to the Drobo using the sparsebundle backup mode of SuperDuper! over the network. This actually effectively doubles the number of backups for each lappy, but centralizes them for efficiency. As you can see below, I've brought the hard drives to school, where I've turned them into a striped RAID 500GB array. Making them striped (as opposed to concatenated JBOD) increases the IO speed by roughly 30% over the standard case. Copying a 3.5GB file to any of them individually (or together in JBOD mode) takes about 120 seconds, but as a striped RAID it takes 80 seconds. 500GB isn't big by today's standards, a 2TB disk costs less than $100, but I already had these disks, so it's effectively free. So, why not?

Heading west on my ride yesterday I saw this curtain of rain falling in the distance. As it happened, I was riding west and I did get rained on by this front a few minutes after taking this picture. It wasn't too bad, just enough to get my legs dirty from spray off my front wheel, mostly.

A few days ago, on Saturday September 10, I attended the collegiate American football match between the University of California Golden Bears and the University of Colorado Buffaloes. Although we've lived in Boulder for over a year, and I work in the football stadium, this was the first Buffs game I have attended.

The game was an exciting one. The Bears led for most of the game, but the Buffs tied the game in the last minute of regulation, sending the game into overtime. Quite surprisingly, the Bears managed to win in overtime, something that as a True Blue, I am not used to seeing from my Bears.

This is the first season where the Buffs are a member of the Pac-12. I think they are not quite up to the standards of the Pac-12. Here are some of my observations from the game.

• The security getting into the game was a perfect example of security theater. They patted people down in a very cursory way searching for who-knows-what. Once inside the stadium, I didn't see security officers in the stadium at all until the end of the game. In the closing moments they were positioned in front of the student section in a weak attempt to prevent the students from rushing the field. How are 20 people in yellow jackets going to stop 4,000 drunk undergraduates? In the end, because the Buffs lost, the students stayed put.
• Note to self: For the next game I attend, I'm putting all kinds of goodies in my office the day before the game. No one seemed to notice when I went inside to get my water bottle this time (to avoid paying $3.75 (!) at the concessions for water), so I figure I can store even more stuff.
• The stadium feels a bit dated, kind of like Memorial was before reconstruction. The isles are tight and the access gates are narrow. The loudspeakers are located at one end of the stadium, meaning that they have to be extra loud to reach the other end. The head referee's microphone didn't work, so we had to guess what penalties were or catch the hand signals (which was difficult because he faced the other way during announcements). However, the views of the front range and flatirons are supreme.
• I noticed several times during the game that the PA people are, frankly, rude. I always thought that music is required to be turned off during plays, but the PA people would let it continue into the beginning of plays. Also, at least once when the Cal Band started to play after a Cal score, the PA played music over them. It's one thing to play over the 183rd playing of "Tribute to Troy" when playing U$C, but it's unacceptable to play over the Cal Band.

The only cool thing about CU is the running of the buffalo, Ralphie. I think there should be the running of the bear. How about a 800-lb grizzly bear running across the pitch at Memorial Stadium?

I know it's September already, but I took this on August 26th.

Seen today from Betasso Preserve on my bike ride. There was no rain or visible lightning, but there was some wind and thunder.
