My hotel/flight package seemed to include some unexpected breakfast credit, so I had a nice omelet in the hotel restaurant downstairs Sunday morning, then set out for Powells, and spent the bulk of the day browsing at the main store and the nearby technical store.

They have a pretty good collection of old computers at the technical book store, which I didn't remember from before. It included, for example, my first computer, the TI-99/4A.

Eventually hunger forced me out. I got a sandwich at a mall food court, ate it sitting on the steps in Pioneer square, then walked back to my hotel, where I read my newly acquired copy of "Vingt Ans Après" and napped a little till it was time to go to the first social event of the kernel summit, just across the river at the Doug Fir lounge.

I wasn't terribly hungry, didn't want to drink while still slightly jet-lagged, and didn't feel particularly outgoing, so I stood around a while at a bit of a loss until David W. suggested a game of air hockey.

Unfortunately the air hockey table wasn't great. The puck was quite light, and we almost spent more time chasing after it than playing.

But we played a long time. The next morning my right arm ached.

After finishing my lunch Saturday I sat around at my (outdoor) table reading a New Yorker, then after getting a call back from Matt I took a quick visit to the nearby central library before going to Pioneer Square to wait for him.

The weather was perfect, and I had a nice time just sitting there, reading a paper, and occasionally looking up to watch passerby.

When Matt arrived we sat on the steps there a little longer and talked, then took his car to drop in on another old college friend, Nat, and his family.

In addition to 3 kids, he and his wife have two dogs, a cat, 8 chickens, two ducks, and some goldfish. I may have missed someone. And, of course, a large garden. They fed and watered us, and kept us chatting till well after night. What a nice evening!

I stayed up late Friday night trying to get some basic raw material sent out to my tutorial collaborator. I fear he may end up doing most of the work, because it's pretty raw.

Then the airport shuttle showed up for me at 7:45 the next morning. The flight to Portland went more quickly than I'd feared. The light rail took me straight from the airport to a few blocks from my hotel, where I checked in, did a little email, got in touch with Matt S., an old college friend who'd recently shown up on Facebook, then had lunch at Maya's, a few blocks from the hotel.

Maya's is a fast-food burrito place. Probably nothing that special, but I like it, and it's one of the first places I ever ate in Portland, when I first arrived as a Reed freshman nineteen years ago.

Note to self: get to bed on time, or you'll be unhappy.

I got a start on a tutorial I'm collaborating with someone on in November, but other than that it was a pretty slow day.

Yesterday was another Sunday spent at the new library branch.

I've got work, and then a weekend of vacation, coming up in Portland. Sara's going to be joining me for a while too. So we've been thinking idly about what we might want to do.

I took a drastic step this morning, and left my laptop at home. I never go anywhere without a computer. But I knew I wanted to pick up a bunch of produce at the farmer's market, then juggle, then meet some friends for dinner, and I just didn't want to be carrying around more than I had to.

Later--maybe 2:30ish--I was standing on the grass juggling, heard applause, looked, and saw passerby cheering on a couple in the middle of the diag. A nearby line of people were holding up signs that together said "will you marry me?". Or words to that effect.

Chris and his daughter Page were in town for a UM football game, so Bill invited me to an early after-game dinner with them. It was pleasant. Page was sort of energetic and goofy and not really interested in having any kind of conversation I could understand.

Mary and Dave seem to be starting some sort of newspaper.--woah. Ed Vielmetti reports on "early reviews".

I spent some time with Sara this evening trying to get Fink set up on her laptop, with mixed results. Fun fact, new to me: fink is German for finch?

We've been doing season 2 of "Buffy" over dinner. The good-guy-vampire Angel and turns bad in the most recent two-episode story. I knew that was coming and thought it would a drag to watch Angel as a bad guy. Actually, it's a relief--I hadn't realized how boring the always-brooding, always-concerned Angel had gotten.

I crashed five computers simultaneously this afternoon. One of them's fine, the other four I'm not so sure of.

The one that survived was my laptop, and the other four were virtual machines running on it that I use for testing. Unfortunately, they were all getting updates at the time, so when I restarted them the dpkg databases that keep track of what software versions are installed were corrupted. I spent some time following some instructions online in an attempt to rebuild the corrupted database on one of the machines, with no luck yet.

The laptop's normally fine, but I think it's frozen up in the same way three times now in the last month or two. I know I had the virtual machines running the last two times at least, so I wonder if it's a kvm bug.

Oh well. I kept fairly good notes on the setup, so in the worst case I think I can reconstruct them all in a reasonable amount of time if I have to.

Still, it's never fun to end the day feeling like you've gone backwards.

At least I got some laundry done in the morning. But why were there *three* of us in the apartment laundry room doing laundry on a Friday morning? My only reason was basically that I thought it'd be an unlikely time for anyone else to do laundry. I suppose that was their idea too.

Chris and Scott, both from my grad school cohort, were in town this weekend, and we met at Bill's condo just before noon Saturday. After having lunch and sitting around a while, Bill suggested a round of frisbee golf; so we piled into his car and he drove us out to a course in Ypsilanti.

Frisbee golf is a big obsession for Bill, and he and Chris get together once a year to go on a few days' tour of courses in some area. I'll never reach his level of accomplishment or obsession, but I can see it being a fun thing to walk through the woods throwing a frisbee every now and then.

I pretend not to care about scores, but really I like winning, more than I should. There was no hope of that yesterday, but I know what I got anyway: on the 18 holes, the number of throws it took me to reach the goal was 5, 5, 5, 4, 4, 3, 5, 3, 4, 4, 4, 4, 4, 4, 5, 5, 4, and 3, respectively. Except that I was confused at first about where I was allowed to throw from, so the first half of those might actually have been a little longer if I'd known. They claimed 3 was par, and Bill was getting a fair number of 2's.

Afterwards another grad school friend, Dave, showed up, and we went downtown to meet Sara for dinner at Cottage Inn. Sara and I went home afterwards, while the others set out for a pub crawl.

I have a working mp3 player again--the previous one broke a while ago, and then I picked up one as an impulse buy in the Detroit airport on my way to Windsor the other week. So I've been catching up on my French podcasts. I feel like my comprehension's improving a little.

One weekly podcast is a word-game show, "Des Papous dans la Tête", a little reminiscent of the old British radio show "My Word", but more more involved, and with a heavy Oulipo influence. I think I get about 1% of the jokes, but when I get one, I feel like I've accomplished something!

With the help of a small TV from a yard sale and a rabbit-ear antenna Dave L. loaned us, we can get fuzzy reception from NBC and CBC. The Canadian station comes in a little better. So once every couple years we turn on the TV for two weeks. It's really Sara that's the fan of the olympics, but then I get mesmerized and find myself staying up later than I should, all to see the end of some contest that I don't really care about.

I wish they could find something better to celebrate than a few really narrow competitions. When they have to turn up the sappy soundtracks and tell you everybody's life story to keep you interested, it should be a sign that what's on the screen isn't intrinsically very interesting.

But, OK, it's kind of fun anyway. I'm conflicted.

This morning as I was getting ready for work they had trampoline on. They need more trampoline.

Tuesday morning I took most of the day off, did some laundry and other chores, then voted in the primary.

I woke up Wednesday morning to find that everyone I'd voted for had won. So anything bad that happens in the next couple years is totally my fault.

It was my advisor's birthday Saturday, so there was a conference in his honor thursday through tuesday. I don't work in the field any more, and didn't think I'd be up for most of the talks, but I went to the Saturday night dinner, and the 10am talks Thursday through Saturday, which were nice surveys of subjects related to his career, together with the occasional personal trivia.

It was all a little like walking back into a room I'd just left and finding everyone 8 years older. Well, the people all seemed the same. (But suddenly there were babies everywhere!) Though I haven't kept up with them, they're all people I like a lot, so it meant a lot to see them again.

Florian even had a math question for me. I spent a few minutes looking back at my dissertation Sunday to look for an answer. Unfortunately I had to agree with him that there was a bug in one of the proofs in my dissertation, and though it looks like it was squashed in the version that later got published elsewhere, the proof in that version is missing an intermediate result that Florian wanted.... So on Sunday I managed to figure out a little, but not to answer his real question. I'll have to give it a little more thought next weekend.

If there were twice as many hours in the week, I'd take up commutative algebra again, though I think I'd rather be doing computational stuff, which isn't something people here seem to be as interested in.
