Monday night and again tonight, Sara and I met at Top of the Park and watched the first band, but didn't manage to stay much longer. I'd wanted to stay for tonight's movie ("Some Like it Hot"), but forgot to bring warm clothes, and wasn't really enjoying the second band ("Stewart Francke & The Regular Boys"). The first band ("Yoshi") I actually liked better.

I wasn't too interested in the Terraplanes on Monday night either. I can only hear so many straight-ahead 12-bar blues in a row.

It was nice out today, so I juggled on the diag again. I've also been taking regular 3-ball breaks during the day. It doesn't actually help my juggling much--my back crosses, what I've mostly been working on, aren't getting better very fast--but it actually helps with work. I concentrate better when I'm juggling on breaks (anyway, at least it's better than checking Slashdot).

I came home after juggling yesterday and haven't set foot outside the apartment since.

In fact, I haven't done much at all. Mostly, I'm alternately napping and trying to relearn what little I used to know about reading Japanese.

I'm meeting some people to discuss the delightful manga Yotsuba&! on Thursday night. I figured it might be fun if I could take a look at the original, and figured with a little work I might be able to make it through at least one of the stories. They're written with kids in mind, so have some helpers ("furigana", which annotate all the kanji). But that's only a small help. And there's also the problem that the little bit of Japanese I learned in college was extremely formal, quite different from the language kids in a comic book are likely to use.

Last night we finished season 4 of Buffy over dinner. The last episode wasn't that interesting. I think I'll forget about Buffy for a while and try to catch up on this stack of French movies that I have checked out from the library.

Maybe I could set a goal to learn a name every day. Yesterday and today I learned six, so I figure I can retreat to a cave for the rest of the week:

• Laurie (if that's the spelling): I'd met her several times before, but since I had to be corrected after introducing her to Sara as "Carol", I figure this counts.
• Daniel: A UM psych prof sitting with Laurie at Top of the Park. We sat next to them a while. He talked about brain imaging a little.
• Tanner: The husband of someone Sara had a class with, who works on Linux and OpenBSD at the Linux Box.
• Liz, Melissa, and Kyle: three friends (from the co-ops, I think) who showed up for juggling today. Most of the jugglers went off to Madison for World Juggling Day. I did the regular diag juggling time, expecting to just be on my own. HD also showed up and we passed clubs for a while.

Sara's mom visited us for a little over a week--she arrived on Amtrak from Arizona late on a Thursday night (the 22nd) and spent a couple days in Ann Arbor, then she and Sara rented a car and drove north Sunday to visit Sara's uncle. They got back Thursday, and Sara's mom caught the train back Saturday morning.

While they were away I watched "Boudu sauvé des eaux", and rewatched "Baisers Volés" and "À Bout de Souffle".

Over the last week or so my dad's been riding his new bike--just picked up from Bruce Gordon--from Portland to San Francisco, a good 80 miles or so a day with what sound like some pretty good ups and downs, too. Yipes.

We got an article in the local paper about our juggling festival a couple weeks ago. I figured that might get us a few more people at the festival or our weekly meetings, but the main result so far has been that we get lots more requests to volunteer work.

None of us really performs, though. I don't think any of us have anything against the idea--it just takes work to put together something entertaining and original, and nobody seems to have the energy. Maybe some day. But occasionally if someone doesn't mind our just showing up, fooling around, maybe doing some one-on-one juggling instruction with passerby--basically the same stuff we do for fun on the diag every week anyway--then we'll show up. So this Saturday a few of us made it out to Chelsea's "Relay For Life", some sort of American Cancer Society benefit. It wasn't that interesting, and we didn't stay very long. I never understood that kind of fundraiser--isn't there some simpler way to get people to write checks?

Before that we had our regular Saturday afternoon juggling thing. There were a couple French students--Arnauld, who'd been before, and Ariel, but who I'd met briefly at Sweetwater's before. Some random passerby that were friends of Dave's also turned out to be French speakers, so hung around and talked to Arnauld for a while.

Then there was also a photographer from the UM alumni magazine--someone at the magazine saw that the Ann Arbor News had run juggling pictures, and figured, hey, maybe they could do that too.

Later in the evening Sara, Paul, Steve S., and I saw a free Jandek concert. Wikipedia can fill you on the details of the whole Jandek mystique; or see this NPR article. Nobody really tries to describe the music, though. So what was it like? This is what I wrote Dave, who decided to skip the concert at the last minute but was still curious:

So there was a harpsichordist, a trumpeter, a dancer/singer, and Jandek.

Jandek had a guitar (was it some kind of bass guitar? I couldn't see from where I was). He'd often start songs playing notes that went up and down a bit and didn't have a regular rhythm, but by the middle he settled in to this very regular thump-thump-thump on the lowest string. It was always about 180 beats per minute, I think. So there was almost always this deep bass drone going on, and every piece had pretty much the same medium-slow tempo.

You can go find his singing on youtube. It varies between just speaking and chanting. He'd start a sentence sliding up to a note, hang around on that note, then drift back down at the end.

The dancer would start sitting up straight in her chair, then stand up, walk a careful circle or two around the stage, or maybe stand in one place and make sort of jerky movements with her arms and stuff. Occasionally she'd stand at the microphone and sing wordlessly, mostly longer notes.

The trumpeter would sort of listen along a while, then join in with an atonal jazzy little solo, and fill in between Jandek's singing.

A lot of the time the harpsichordist was just jabbing out these occasional little chords, like a jazz pianist comping behind a solo. Sometimes he'd do more complicated stuff with some syncopation and multiple lines going on at once.

So how was it? Who knows? I think I napped a little during the first few songs. By the end, once I'd resigned myself to the thump-thump-thump and the unchanging tempo, I actually decided some of the music was kind of pretty, and that the harpsichord was doing some interesting stuff.

The harpsichordist and trumpeter were clearly very proficient musicians. I thought the dancer had a good voice too, and liked her singing. I know nothing about dance, but suspect she's pretty good at what she does. As for Jandek himself? I just have no idea. Anyone could have done that stuff, I suppose, but, hey, I've never heard anyone else do it, so if you were into that kind of stuff, I guess he's the guy to go to. Personally I thought we could have replaced him by a machine that went thump-thump-thump and not missed much.

A lot of people left between songs. Some songs would have a particularly large exodus at the end--we could never figure out why--they mostly sounded pretty much the same, so it's not like you could say that the song that a lot of people left after was any more annoying than the previous ones.

There was a standing ovation at the end (assuming it wasn't just people anxious to leave), yet another data point in support of our hypothesis that Ann Arbor audiences give standing ovations to anyone.

The flight back to Ann Arbor was long--we changed planes in Atlanta. It was almost uneventful, except that--well, I must have had something bad to eat at some point along the way, because I started getting slight cramps just as we were boarding the plan from Atlanta. By the time we'd taxied out they were getting painful. I asked the attendant behind me if I could get up, and the answer was more or less: yes, but we'd have to stop the plane. So I had a couple more agonized minutes (we weren't first in line for the runway), then made a dash for the bathroom, and all was well for the rest of the trip.

I volunteered to give a Connectathon talk on using git to track nfs development work, so spent a lot of time trying to put together some notes and a visual aid or two. It still ended up a little rough, but maybe it could be polished into something useful one day.

Monday night I got to see Scott U., a high school friend who I probably hadn't seen in 15 years or so. We had a nice conversation, and he seemed to be doing well, but the more interesting story is the trip there.

We'd arranged to meet at a restaurant next to the Redwood City Caltrain station. I was just a few blocks from the San Jose station, and Caltrain just has the one track (which goes from Gilroy to San Francisco, with a lot of stops in between). So this was a very simple, convenient plan from my point of view.

The catch is that Caltrain has a rather complicated system of express trains. There's no simple choice between "local" or "limited" trains--there are actually 5 or 6 different patterns of skipped versus not-skipped stops.

The San Jose station doesn't, as far as I can tell, have any clear signs telling you which platform to go to, and thanks in part to that I'd just missed the 5:05 train, an express which I knew would stop at Redwood City. No big deal, as I'd allowed some extra time. Another train was waiting. There also weren't any signs to tell which train this was, so I asked the uniformed guy sitting on the platform if that'd take me to Redwood City; he said yes, and I got on.

After a twenty to thirty minute wait, it pulled out of the station, at which point the conductor announced that it *didn't* stop at Redwood City. So I found the conductor, who turned out to be the guy from the platform. He was very apologetic, and advised I get off at Palo Alto ("much more interesting place anyway", he said) and then take the train that'd be right behind us.

Of course I double-checked against the schedule posted in the Palo Alto and saw that the next column of the schedule was for a 6:16 train that did indeed stop at Redwood City.

I was suspicious when the next train that pulled up was a few minutes early, but since the schedule and the previous conductor seemed to agree that the next train went to Redwood City, and since everybody *else* on the platform was getting on, and since there weren't any signs to tell me what else to do, I figured I'd try it.

There was an announcement after I got on, but I didn't hear it all. After watching the train woosh along for what seemed like too long, I asked a neighbor if they had a schedule I could borrow. At which point I realized what had happened: the columns of the schedule were not actually in strict chronological order. Or rather, they were in order for the originating station (San Jose), but the mixture of fast and slow trains meant they weren't necessarily in order for later stations (like Palo Alto) any more. I'd gotten on the train which left Palo Alto at 6:06 (listed on the schedule just to the right of the 6:16 train), which didn't stop till 3 stops after Redwood City, at Hillsdale.

This time I checked the schedule extremely carefully, and caught a train from Hillsdale that got back to Redwood City a little over a half-hour from when I'd said I'd arrive. I had a phone with me and was able to warn Scott, so it all worked out.

So I ended up taking three trains to do the job of one.

The trip back, fortunately, was much more straightforward.

On Sara's suggestion I mailed the above story, plus a little bonus whining, to Caltrain. I wonder whether they'll respond. I mean, it was partly all down to me being an idiot, no doubt, and a freak wrong answer from a conductor, but the occasional sign might have helped.

There's a bus now that goes between Ann Arbor and the airport, so I figured I'd try it just out of curiosity. The bus itself is fast, but only comes every three hours or so, and only to one location well outside downtown Ann Arbor, so the whole trip ends up taking a while. They've got free wireless, which I tried and it was OK. I wonder how it works? It seemed to keep working through the tunnels, but gave out when we got to the parking garage area across from the terminal.

There was about an hour's delay leaving Minneapolis, but other than that both flights were routine.

At Connectathon I've found one good Linux bug, and a bunch of bugs in other people's stuff. Virtualization has been a big help--thanks to kvm I've essentially got four little virtual test machines running on my laptop that I can run experiments with without disturbing the rest of my work. There were some minor hassles getting it all set up, but it's worth it.

It's weird eating out all the time. I quickly find myself looking for the smallest things on every menu; it's easy to forget how rich restaurant food is, and how large the portions are.

I'm not cut out for this. Every now and then I think it'd be nice to write a paragraph every day, but then when it comes to the end of the day, I say "eh, I can write about that tomorrow", and by the time I get around to it I've forgotten what's happened.

This weekend was the annual local juggling festival. We got some coverage from the Ann Arbor News this year, but attendance seemed about the same as usual. For me the most fun coverage is from Homeless Dave, who brought his teeter totter for us to play with in the morning and did a few interviews.

I ran the games this year. I didn't have the time to prepare the week before, so it was a bit rough, but people seemed to have fun.

Sara and I went out to dinner with a group to a Korean restaurant named Seoul Garden. I had some bibimbop. I felt like they skimped a little on the side dishes (always my favorite part), but it was otherwise great.

Then to complete the already long day there was a party at Fred and Deanna's.

They had a puzzle in the form of a dodecahedron with a lit-up button on each face. It starts with a random configuration of lit and unlit buttons. Pressing a button toggles the lights on the five neighboring buttons. The goal is to light all the buttons.

My math is getting sadly rusty, but I still recognize when something is linear, hence easy, so I fooled around a little, and eventually realized the nice way to look at it: given a button, call it "odd" if an odd number of its five neighbors are lit, and "even" if an even number of them are lit. In the winning configuration, for example, all twelve buttons are odd, since all 5 (an odd number) of each button's neighbors are lit up.

Then the trick is to notice that pushing a button changes the parity of the button you pushed (because if n of the 5 neighbors were lit before, 5-n are lit now, and n is odd iff 5-n is even), but doesn't change the parity of any others (it's easy to check that every other button borders on either zero or two of the buttons that are being toggled, and that toggling two neighbors can't change a button's parity). It follows that you can produce any desired pattern of odd and even buttons. And that there's a very simple algorithm which always produces the shortest possible solution: just find an even button, press it, and keep going until no buttons are even.

Anyway. Today we were pretty tired out. We both napped some, and I did a grocery run in the afternoon.

Wednesday I leave with Fred and David for Connectathon. I've been using kvm to set up virtual machines on my laptop to use for testing. It's been working really well. Effectively it means I'll have all the test machines I could want without having to carry more than the one laptop.

The public library no longer keeps holds behind the desk; so if something comes in, you look for your name on a shelf and pick it up yourself. The checkout is (optionally) self-serve at this point too, so you can do the whole thing yourself.

Today I got to the bus stop (across from the library) about 4 minutes before it was due to leave, and figured I'd try to go pick up a hold. And I was impressed by how fast it was--I picked up the book, scanned my library card and the book, and I was done. So, I'm a convert to the new system. I even had time for a quick bathroom stop before catching my bus.

Yesterday was a fondue party with the French conversation group. I borrowed the equipment from a juggling friend, read instructions on the web, picked up ingredients at Bello Vino, and it went fine. The food and the company were good, and the place was just a few minutes' walk from home, but though the people were nice, I was a little tired and not really in the mood to make an effort, so as a social event (or French exercise) it was pretty minor.

They had pastis, which is weird stuff, but neat.

Saturday night we played a game called "Niagara Falls" at Fred and Deanna's. The board and pieces are lovely, and the game seemed pretty fun too, though we only started to really figure it out at the end.
