Another month gone by, more work, more scouting
Another month almost gone without an entry. Work is pretty much a continuation of the same. Development of the GSE software continues, albeit slowly.
A USC grad student in computer science visiting us periodically volunteered to help me get the fancy new Dell laptop to work with the big Dell monitor while running Ubuntu. The problem wasn’t so much that it wouldn’t work but that it wouldn’t boot with the monitor attached; my workaround was to boot without the monitor and then, after the video driver loaded, attach the monitor. Unfortunately, he got nowhere fast over a couple of weeks. It seems that all of our computer experts are not experts in the things I need them to be experts in. Eventually, he suggested reinstalling Ubuntu, and I agreed to let him do it over a weekend. I wasn’t thrilled, and I eventually found time to try it myself. I actually reinstalled Ubuntu, and it didn’t work, but then I realized that I could just turn off switchable graphics and disable the Nvidia graphics chip, forcing the laptop to run off the Intel graphics chip. Nvidia has horrible support for Linux, anyway. That turned out to be the solution, and the laptop boots into Ubuntu with the monitor attached, and I don’t need the grad student messing with the computer any more, so I don’t have any GSE development downtime whenever he shows up.
It also turns out that I have to give one of many presentations for a CDR — a Critical Design Review — for Solar Probe in January. I’ve never done one of those, and I had to scramble to put together a rough draft a couple of weeks ago.

At the beginning of the month, J and W had their first piano recital of the academic year. J played two minuets by Bach. He did very well, and the little mistakes were the kinds that probably only he, Vatche, and I noticed. W played two movements of a Clementi sonatina. He also played well, very elegantly, with a stumble in the second movement from which he recovered without panicking. Vatche seemed satisfied.
——
W has started the cycling merit badge for Boy Scouts, and I have started riding with him. The riding portion includes 200 miles of riding, spread out over several weekends. After the initial 5 miles startup ride, I decided that my ~20 year old bike was completely inadequate. It’s simply too heavy, and it’s designed for local riding, e.g. short commutes and riding around campus. I bought it while a grad student.
So, after doing a little online research, I went out to the Pasadena Cyclery (which gives a Boy Scout discount) and bought a Trek 1.1, which is a much more modern bike. It has 16 speeds (I think), and it weighs a lot less than my old bike.
For the second weekend, I skipped the ride with W because I took J out on a Cub Scout Family Campout, while Hsuan to W that weekend to a Boy Scout hike on the Saturday and then dropped him off for the bike ride that Sunday.

The Cub Scout campout was pretty much the same as last year, and it was the same 3 hour drive away, north of Santa Barbara, so J and I arrived in the late afternoon. We missed a hay ride, but we were in time for a hike. About 87 people (cub scouts and parents) started, though 4 turned back after we went a quarter of the way on the 2 or 3 mile hike. I was the sweep, bringing up the rear, so I had to determine if it was safe to let them go back on their own, and luckily, they gave up early. It was a pretty steep climb. Also, the hills were surprisingly populated with tarantulas, much to my discomfort.

Anyway, it was a comfortable campout, and J was very helpful in not only setting up our tent but also in taking it down and packing it away when we left by 8 AM the next morning, so we could get back in time for Sunday School.
-----
The day after the Cub Scout campout, we went to Legoland for the Columbus Day holiday, which the boys had off from school and which I took as a vacation day. It still feels a little young for both boys, but J is still very enthusiastic about it, and W is simply open for anything.

We visited the Sea Life aquarium, which we hadn’t done in quite a long time. It was a nice alternative for the morning, but it’s hardly an attraction to make a special trip for.
One thing striking about this visit to Legoland was the huge number of identifiably Jewish visitors — men and boys with the yarmulkes, the hats, the tassels hanging from (I assume) prayer shawls, and so on. Conservatively dressed women and girls. I’d have to say that more than 25% of the visiting population were of this group. I couldn’t tell if they were all from Israel or if they were just from some really big Jewish Community Center tour group from somewhere in America, but I felt it might be rude to ask (and certainly a risk of offending if I were to approach a female to ask — if I had asked, I’d have to ask a man).
I never found out.
——
The next weekend (last Sunday), I was able to ride with W, and I really loved the new bike. The gearing makes getting up hills so much easier.
At one point, W got a flat as we approached the Rose Bowl during our 15 mile ride. We had no spare tube or patch kit, but we were able to call ahead and get one from another in our group. Lesson learned, and I bought a patch kit later.
Another lesson learned: My new bike has toe clips, and it takes getting used to. As I tried to start riding, I had a hard time getting my right foot in the clip on the right pedal. Then I had a hard time getting my left foot in the left clip. By the time I got my left foot in, my bike had stopped moving, and I started to fall to the left, but then I couldn’t get my left foot out to catch myself. So I fell to the ground, managing to protect my bike from scratches by skinning my knee. Two women jogged by and asked if I were okay, adding emasculation to injury.
It didn’t hurt at that time, but by the middle of the ride, my knee was a bloody, clotted mess, and by the time we got back to the car, it was starting to sting. I’ve been cleaning and dressing the wound all week, and it’s taking its time in healing.

This weekend, W and I went away on a boy scout backpacking trip to Henninger Flats, in the mountains just north of Pasadena and Altadena. It’s this year’s beginner’s backpacking trip for the troop, but just because it’s a beginner’s trip doesn’t mean it’s easy.
Henninger Flats is a small forested basin on the side of the San Gabriel Mountains about 2600 ft above sea level, just above Altadena. You can get there by taking the Mt. Wilson Toll Road, a dirt road that starts in Eaton Canyon in Altadena and winds its way up 1400 ft in elevation, over about 6 miles, to Henninger Flats and extending beyond. It’s a very popular hiking, jogging, and mountain biking trail, though it’s with a 25 pound backpacking pack on your back, you can expect it to be somewhat more challenging.
Our troop went up in two groups, and W and I joined most of his patrol in the earlier, 10 AM Saturday morning departure group. We wanted to leave in the earlier group because we knew the earlier departure would have lower temperatures, and the earlier arrival at the campground at Henninger Flats would allow us better choice of locations to pitch our tent.



The hike was grueling, to say the least, though I found it easier than the Cooper Canyon backpacking trip from last year. That trip had a net elevation change of 250 ft, but the starting point at Buckhorn Pass was already around 6000 ft, the trail then dropped 500 ft, and then climbed 750 ft. And that trail was a forest trail, not a dirt road, like the Mount Wilson Toll Road. So even though we were going up all the time on Saturday, I just kept a slow, steady pace, periodically sucking at the bite-valve leading to my hydration bladder.

After noon, we got to the campground and had our sack lunches, and we found the Henninger Flats to be a very nicely forested area with a spectacular view of the Los Angeles Basin below. Our patrol pitched our tents relatively near the edge — but not so near as to be dangerous, of course.


Then, we simply had a lot of time to kill. The scouts were originally going to do the Nature and Plant Science Merit Badge, but the counsellor who was going to lead the merit badge had a sudden family emergency the day before, so it had to be postponed. Instead, the trip was re-planned around scout sign-offs for rank advancement, so scout instructors went around teaching scouting skills as needed and giving sign-offs to those who needed them.
Our scoutmaster is shopping around for a new backpacking tent, and with all the various models of tents around, he got to spend time walking around and taking a look. I put in a good word for the REI Half Dome 2, which is what W and I use.

Otherwise, between sign-offs, we either explored the area, sat around talking, or even took naps in our tents. We even had decent cell phone reception.
The afternoon group left the departure area around 1 PM, and by mid-afternoon, we could see them on the trail. From our vantage point on the cliff, it was pretty hot, so it must have been blazing hot on the trail below, in the exposed sunlight. They finally arrived just around 3:30 PM.
S., one of the 1st Class Scouts, gave some basic instruction in plant life in the area, and then an LA County Fire Fighter stationed at Henninger Flats gave some of the scouts a more detailed walking tour of the trees and other plant life in the area, and several of us dads in the patrol also went along.
We had dinner at around 5:30 PM — just freeze-dried backpacking food bought at local sporting goods stores down below. W had selected mac and cheese for the two of us. Others had whatever they bought. Just boil a cup or so of water, pour it in the pouch, seal it, and let it stand for about 8-9 minutes, according to the instructions. Then open and eat, and discover that 8-9 minutes isn’t enough time to soften the freeze-dried stuff completely. Same as at Cooper Canyon.
For the evening, some of the scouts had a sign-off with dads who were lawyers, who gave a combined talk on the rights and responsibilities of American citizens. It was basically what Tom did at the whitewater rafting campout, but this was several dads giving the talk, and it was troop-wide. Although W had the sign-off (though not with Tom), I had him go with them, for review.

Meanwhile, those scouts and dads not involved in that particular sign-off hung out at the cliff, listening to music, talking, and getting a spectacular view of Altadena, Pasadena, and the Los Angeles basin area.
We had a spirit conference after the sign-offs were done. All the scouts had to participate and give examples of some exercise of one element of Scout Law. And after that, we made sure all our food and other nice-smelling items were packed away in the bear locker before lights-out at 10 PM.

Sunday morning, we all arose at 7 AM and began packing up. However, we also had our newly instituted camp cooking competition between patrols, this time for breakfast. The competition was to make the best backpacking breakfast. Our plan was to do pancakes, but to dress them up really well. Ben brought Bisquick instant pancake mix, and Prashant brought Tang, canned whipped cream, granola, fresh bananas (technically not allowed — no fresh foods on backpacking trips), walnuts, cinnamon, and other assorted fixings.
I brought the pancake syrup mix — 1 cup white sugar, quarter cup brown sugar: Add water, heat to a low boil (we had several backpacking stoves), and add a dash of vanilla extract and maple syrup flavoring. It was heavenly, and you could smell it from several feet away. Word spread around camp, and people came by to see, to ask about the syrup, and to get a taste.
We also had our freeze-dried breakfasts that included things like scrambled eggs, so after cooking (or reconstituting) some of those, we were able to add those to a plate.
In order to complete one part of their cooking merit badge requirements, each scout had to prepare at least one pancake. (They also had to cook their own dinner the night before, i.e. boil water and pour it into the bag.)
The senior patrol leader and assistant senior patrol leaders were the judges for the competition, and they eventually came by and had a taste test. I told Daniel that it felt like Top Chef Boy Scouts. Our scoutmaster also tasted, and we had a bit of worry when he pointed out that fresh fruit (the bananas) technically violated the rules of the backpacking cooking competition, since you don’t bring fresh foods on backpacking trips. (Prashant missed that part of the e-mails.)
In the end, however, our patrol won the competition. I guess our results were so much better than those of the other patrols. Also, some of the senior scouts pointed out that they were provided with fresh fruit at one or more of the stops on the Philmont backpacking trip this past summer, so they gave us a pass. As reward for the win, our scouts won a Starbucks gift card.
——
After breakfast, we cleaned up and finished packing. The scouts and most dads had a nondemoninational prayer/religious service at the cliffside, while the leftover dads (including myself) finished cleaning up. Then we had a camp sweep to pick up the last remaining bits of trash, and we headed out around 9 AM. The hike down was all downhill, so we didn’t stop much except to regroup as the line stretched out too much. We met a lot of people coming up as well as several people passing us going down (bikers and joggers, mostly).
I had texted Hsuan to be ready to pick us up around 10 AM, and she and J were there when we finally arrived around 10:20 AM or so. No root beers this time, but some entrepreneurial kids had set up a gatorade stand nearby, so I had W buy us a couple of bottles. We were all exhausted. After saying our goodbyes, we gave Ben and L a ride home, and then we went home ourselves.
First month of school, scouts, gliders...
Have I really skipped writing about the entire month of September? I guess I’ve been that busy.
Let me breeze through work first: I’ve been scrambling and behind schedule writing the software for testing the Solar Probe spacecraft instruments. We had to order a new laptop and a giant monitor to go with it, and I had delayed getting them because I wasn’t sure they’d run together and also run Ubuntu 14. Our IT people said the hardware should be compatible with each other, but there are always software issues.
When we finally got the hardware in, I realized the monitor was so much larger in person than I expected that I felt like I had to start reconfiguring the software displays. To get started, I hooked the monitor up to my MacBook Pro and worked from there, ignoring the new PC.
I also struggled with the GSE software. I simply don’t like the way it handles memory, with a lot of things having to be “hard coded” rather than dynamically allocated. I spent a lot of time working things through in my head rather than writing things down. Maybe I spent too much time thinking about it before I got to writing it. However, when I finally started the writing — and I wrote code to write code, which I think I was forced to do by the memory architecture — things went pretty fast.
Because of all the delays, I also ended up skipping an ACE Science Team Meeting last week at APL, as well as a follow-on STEREO Science Team Meeting afterward. I feel like I was simply swamped with the Solar Probe work that has deadlines coming up.
So while I was stuck here last week, I finally got started trying to install Ubuntu on the new laptop — and then I ran into trouble getting Ubuntu on that laptop to work with the new big screen. The older laptops work with the new screen with Ubuntu 13, via HDMI, just fine. The new laptops work with the new screen with Windows 7. The problem is with the new laptop and Ubuntu with the new screen. I spent two days working with it, and it seems that the problem was with the Nvidia driver not loading before the login screen loads. The workaround is to keep the screen unplugged until after boot.
But that ended up being a waste of two whole days.

The boys have been doing pretty well at school for the new year. W tried out for the football team and wound up on C team, which is basically intramural flag football. He also got on one of the debate teams — he was recruited for it, actually. It seems to be a big thing for a lot of people, and he really wants to do it. Personally, I think debate is just one step up from things like drama club and many, many steps below things like science, math, and engineering. I told him, “Debate and rhetoric are the stupid, ugly cousins of logic.” Oh, well, if he enjoys it.
W also finished his spring term as Patrol Leader of his Boy Scout patrol. He and V, his assistant patrol leader, scrambled to complete the last two requirements of their leadership positions — to have two patrol-only activities (outside the Troop activities). One activity was a bowling party that W organized on Labor Day weekend, and the other was a swimming party at V’s house on 9/21. Their leadership positions expired on 9/22, so they finished under the wire.
W then volunteered for another leadership position. He didn’t want to do Patrol Leader again (or Assistant Patrol Leader, which is effectively the same as far as he was concerned), so he got Troop Librarian a member of the Troop Multimedia Team. We’ll find out what that means later, when he gets his leadership requirements. When the leadership positions were announced on the 22nd, he was mistakenly announced as Troop Historian and given the Historian patch, but that was a mistake (and also not his request).
V asked for and got Patrol Leader, and L, another of their friends, asked for and got Assistant Patrol Leader.
This past weekend, W and I went to Llano, CA for the Troop Glider Campout. We drove out early Saturday morning, arriving at Crystalaire Airport there, a private airport housing a glider school. We also drove V and his older brother R, because their dad was unavailable that weekend.
The Scouts (and dads) attending the campout were divided into groups, and W and his patrol took the Aviation Merit Badge class in the morning. In the afternoon, each Scout flew in a glider, with an experience pilot in the rear seat, for anywhere from 20 to 45 minutes. All of the scouts had fun, though many reported having to exert some control not to throw up during the flight. (They had all been warned not to eat heavily before their flights.) In fact, W barfed (just a little) into his barf bag just before landing.


Some Scouts flew in the morning and took the Aviation Merit Badge class in the afternoon. And some dads also flew, though at $100 per flight, most dads didn’t. Being a little concerned with airsickness as well as not wanting to spend $100, I didn’t sign up to fly, but as I watched so many flights take off and land oh-so-slowly during the day, I started wishing I had signed up. At mid-afternoon, when all the flights were done, one of the airport staff asked, “If any of you had the chance to fly, would you do it?” I raised my hand and said yes.
Then Patrick, the dad who arranged the campout, said, “If you get me a check for $100 later this week, you can fly now!”
I said, “What? I thought that was just hypothetical. I wasn’t expecting to fly, and I just had my lunch!” which was really true — I had waited to have lunch with W, as most of the dads waited to have lunch after their sons had flown. The woman who had offered the flight said that the air was really choppy then, so it probably wasn’t a good idea for me to go up on a full stomach.
——
The campout afterward was nice. Although it was in the desert, it was a lot colder than I expected, and it was very, very windy. Our campsite was at the end of the airport, way beyond the end of the runway and about 500 yards from the main buildings of the airport, where the restroom was. The winds were so strong at times that setting up the tents was very hard, and staking them down could be iffy without really good stakes. Our rainfly ties slipped off the stakes at night.
The bathroom situation wasn’t too bad, either. At least it was a real bathroom with a flushing toilet. If you weren’t in a rush, it wasn’t too bad to walk, and otherwise, dads drove the scouts to the bathroom.
During tent setup, a few of us drove to the Devil’s Punchbowl area for a hike, but we got such a late start that we ended up just visiting the nature center there and then driving back. The hike was about 40 yards. But we saw a couple of owls they had there.

Our patrol cooked spaghetti with meat sauce. We didn’t bring our patrol box, so W and I provided our own camp stove, spaghetti noodles, plasticware, and cooking gear, while the other scouts brought the ground beef, Ragu sauce, and other stuff. I taught the newer scouts how to brown the ground beef and then add the sauce, and I taught them how to cook the pasta. Our propane ran low, and the water wasn’t boiling, and there was a scout campfire (Scout Spirit Conference) coming up soon. We were in a rush, so I swapped out the propane, and the water heated faster. We ended up with the spaghetti at a reasonable approximation of al dente entirely by accident.
——
The next morning, there was to be a sunrise hike. Any scout that wanted to hike was to wake up at 5:45 AM, meet by the campfire meeting area, and then go hike by the aqueduct to see the sunrise. Only six scouts bothered to wake up and show up for the hike, including W and one of his new patrolmates, N, plus two senior scouts. I and Kelly, a former Scoutmaster, were the only adults to show up.


We hiked to the aqueduct and then walked beside it, and we caught the sunrise at about 6:53 AM.
When we returned to camp, everyone else was already awake and almost finished with breakfast.
