Blog move

2007-12-06T21:08:18Z

I'm going to try blogging here and see how it goes.

I'll continue to read my friends and communities on LJ, though.

wordpress.com

2007-12-04T23:45:22Z

While I'm not as down on LJ as some people are, I have been feeling a little discontent with it lately, and the recent Facebook Beacon fiasco only adds to my wariness about big social networking sites. So I'm considering moving my blog to another site, and I'm wondering: anyone out there have anything to say about wordpress.com?

Bye, Facebook

2007-12-04T14:58:11Z

Nope. Not gonna take it.

Added: Oh, and also: Nor this.

Happiness is AppleCare, at least if they're doing it right

2007-11-28T14:48:09Z

I've had my MacBook for about a year and a half now. I'm not big on extended warranties most of the time, but for a laptop? AppleCare. No question.

Until last week I'd used it twice.

Once a DVD (from the library, and due soon!) got stuck in the DVD drive and wouldn't eject. AppleCare phone guy talked me through coaxing it out.

Another time (just a couple weeks ago, I mentioned it here) the power adapter seemed to stop working. AppleCare phone guy had me reset the power system and all was back to normal.

Last Tuesday my MacBook abruptly froze up, and wouldn't restart from the hard drive. I rebooted from the install CD and ran Disk Utility: all signs pointed to a hard drive crash.

Wednesday morning I called AppleCare. Phone guy had me check a few things and then confirmed my diagnosis. He said to take it to the local Apple Store, have a good holiday, bye.

What he didn't do, and should have:

Tell me I would need an appointment at the Apple Store

Offer to make the appointment for me

Give me a confirmation number

All of which I did not find out about until I arrived at the Apple Store, Kenny in tow, to be told they couldn't help me that day. No appointment slots left. I could come back Friday. Black Friday, at the Apple Store, in the middle of the biggest mall in town half of whose parking lot is gone due to construction. I implied that this was unlikely.

After the fourth or fifth time I told them the phone guy had not given me the above information which, they said, all phone support personnel are required and trained to do, the person I was talking to (who was very nice about it) got on line for a minute, checked in back, and then said they could take care of me. I signed the form, handed over the laptop, and left. They sent it off to, apparently, Tennessee.

FedEx attempted to deliver the laptop Monday, though (partly due to my own screwup) they didn't get my signature for delivery until today. Yep, dropped it off the day before Thanksgiving and it was back the Monday after. I'm letting it get up to room temp, and then I'll start restoring accounts, applications, and files.

Addendum: It says here:

If I'm interpreting this right, it looks like they replaced not only the hard drive but the motherboard, about half the case, and a few other assorted parts. The case does look decidedly fresher.

Also, just yesterday I found out about this. I don't know if my drive was one of the affected ones.

The clarinet report (edited)

2007-11-21T05:57:32Z

Edited the next morning to clarify a few points.

I did it again. Bought a clarinet on eBay. I can't possibly pretend I need another one -- I have three soprano clarinets already, and I've only used one of them the past several months. This one I bought pretty much out of curiosity. It's a Mazzeo system clarinet; I've never seen one in the flesh. I figure buying one for $17 (plus equal postage) is a pretty good way to get a good look at one. After which, who knows, maybe I'll resell it. I might even be able to make a tiny profit.

We're coming up on our last band concert of the year, in two weeks. The next week there's a pot luck dinner, and then we're off until March, the anniversary of my joining. I've had a good time, and my playing's improved. Not that I'm not still a tyro, but I've made a little progress.

I'm enjoying being in the third clarinet section a lot more than I ever expected. I started playing clarinet in the fifth grade, and partway through sixth grade my teacher switched me to bass clarinet. I played alto clarinet in seventh and eighth grades, and then bass clarinet again in ninth through twelfth.

I really enjoyed that. Most of the band parts were rather dull, a lot of oom-pah oom-pah and not much else, but I just really liked the big, fat sound of the instrument, particularly in the bottom octave, and though it takes more air than the soprano it accepts a looser embouchure, so I found it more fun to play.

I was back on soprano clarinet for a year or two in college, but by then I was thinking of myself as a bass clarinetist in exile. The bass was always my favorite clarinet, and I got much less enjoyment out of the soprano.

When I got interested in playing again a couple years ago, I started looking for a bass clarinet on eBay. I found one eventually, but in the meantime picked up an alto and a couple sopranos when I could get them too cheap to pass up. When I contacted the director of the LaFayette Concert Band I told him I had soprano, alto, and bass clarinets, and hoped he'd ask me to play bass. Instead he wanted me on soprano, and I was a bit disappointed by that.

But if he offered to let me switch to bass today, I'd have a hard time deciding whether or not to take him up on it. (Not that that's likely -- we have a bass clarinetist, and don't need two in a band our size.)

I've re-learned something I'd forgotten, which is that even the third clarinet parts tend to be more interesting than the bass parts. And, not unrelatedly, it wasn't just time away from playing that accounted for my limited skills: they'd been stunted by my time on bass. Not that playing bass isn't an enriching experience, but it didn't help my embouchure any, nor my dexterity, nor my facility in the altissimo register. Bass clarinet is great fun to play, but playing soprano is good for me. And also fun. My teenage disdain for the soprano is gone.

I do hope to find an opportunity to play bass clarinet again at some point. And I'd love a chance to try out a contra clarinet, although at this point I can't afford to buy even a cheap used one. Right now, though, I'm happy on third clarinet. Second would be great too, someday, when and if I hone my skills well enough and an opening exists, but third is fine until then.

Meanwhile, back on eBay, I'm paying attention to the occasional Bundy eefers...

The thrill is gone

Well, I've seen Comet Holmes again, tonight. The sky was clear enough in the early evening to get a glimpse -- an hour later it had clouded over in the east. But the comet was a very different sight than it was ten days previously. It's gotten bigger, which makes it more diffuse, and the Moon is in the sky, washing everything out. So what was, through binoculars, a stunning clear blob a week and a half ago tonight was a barely visible smudge. Naked eye visibility was hopeless.

A day ago Holmes's coma was between us and Mirfak (Alpha Persei), and that might've been a sight worth seeing. Unfortunately it was cloudy here. Tonight the comet was just above Mirfak.

So I think the previous sighting will have to stand as the one good one -- unless, of course, Holmes repeats its 1892 trick of brightening twice.

Finished, first of four dinosaurs:

From this pattern. It was decidedly a learning experience. I learned, for instance, how to knit in the round on double pointed needles, and why not to use metal DPNs when starting with six stitches cast on. I learned to look in my knitting bag for a missing DPN before looking down inside the sofa. I learned a decrease (ssk), an increase (kfb), and short row shaping. Having decided to make the thing a little less boring (single color acrylic worsted, now that's boring) by making its feet a different color, I learned another way to do jogless color changes (as opposed to colorless jog changes). I learned how to hide and secure yarn ends when working on a closed, stuffed object ... thanks to a response by the pattern's author to my question. I learned how to do I-cord. I still have not learned why it's called I-cord.

I was going to make the t-rex next, but Kenny wants a t-rex and his dinosaur is lower priority than his cousins', so I'll follow his request and make a stegosaurus for Mitchell, and then the t-rex. I'm not sure who's going to get the triceratops. I'm sure I can find someone.

A couple more photos here.

Namesake and nebulosity

2007-11-11T03:09:32Z

We haven't had many clear nights lately, and on what few we've had I've forgotten to go out and look. It was mostly clear tonight, though, with a day old moon, and the next several nights are forecast to be cloudy. It was, in other words, possibly our last, best chance. Kenny and I went out in the driveway with a pair of binoculars and saw Comet Holmes.

I'm pretty certain we're no close relations to the 19th century English amateur astronomer, Edwin Holmes, who discovered that comet 115 years ago. Still, one can't help identifying, and it's nice, I think, that Kenny's first comet was one he shares a name with. It's my third or fourth, I believe. I was too young for Arend-Roland in 1957, and I don't think I saw Seki-Lines in 1962. I may have seen Ikeya-Seki in 1967, though I don't remember it clearly. I don't recall anything about Bennett in 1970 or West in 1976. (West should have been spectacular, and I as a high school junior interested in science really should have known about it and seen it, but I didn't; apparently it was very underpublicized after the 1973 Kohoutek fiasco, and maybe that accounts for it.) I did go looking once or twice for Halley in 1986 but with no success. So the first two comets I saw and remembered clearly were Hyakutake in 1996 and Hale-Bopp in 1997. McNaught earlier this year, of course, was too far south for me to have much of a chance at, and I didn't see it.

Holmes isn't as spectacular as those, but even in our less than ideal environment and with little time for dark adjustment Kenny and I could clearly see it as a faint spot off Perseus's shoulder. Through 7x50 binoculars it showed clearly as a big fuzzy round spot, in clear contrast to the pointlike stars around it.

I pointed out the Pleiades to Kenny, too, and then we went in. But in reading about Holmes's discovery of the comet while observing the Andromeda Galaxy, M31, I was reminded that I've never seen a galaxy beyond our own. Which is ridiculous: M31 is a full fledged spiral galaxy larger than our own, and practically next door; it's a naked eye object under the best conditions, and easily seen with binoculars, or so they tell us. I did go out looking for M31 a couple years ago but I guess I didn't have a good chart. Enough, I said tonight, and after Kenny went to bed I went back out with Stellarium running on my MacBook and pretty easily found it. A smudge, dimmer than Holmes in the binoculars and nothing I could see without them, but definitely there. So I have now (finally) seen light that's 2.5 million years old.

It's fixed

2007-11-07T16:10:40Z

Yesterday my MacBook's power adaptor seemed to die. No light, and the battery wasn't charging.

This morning I called AppleCare, and they suggested doing a reset of the laptop's power system. (Unplug it, remove the battery, hold the power button down 5 seconds.) Now things are working again.

So now you don't have to call AppleCare if this happens to you.

It's here

Conspiracy

2007-11-05T15:57:36Z

Heather and I have been watching Stargate. Never having seen SG-1 on TV, we started borrowing the DVDs from the local library system, and more recently from Heather's mom.

We missed a bit of Season 1, though. The Syracuse central library has Stargate SG-1, Season 1, disks 1, 3, 4, and 5, but not disk 2.

The Baldwinsville library, part of the same system, has Stargate SG-1, Season 1, disks 1, 3, 4, and 5, but not disk 2.

No problem, as of a couple of weeks ago we're Netflix members. (Yeah, I know, I know, what took us so long, everyone else has already abandoned Netflix for Blockbuster, blah blah blah). So I went there.

Netflix has Stargate SG1, Season 1, disks 1, 3, 4, and 5, but not disk 2.

Allegedly Heather's mom has it, and allegedly she's going to loan it to us. Or will she? She is obviously part of this Goa'uld conspiracy.

Did I mention the Cooperstown gig with Thornden and the Harridans? Or the Garlic Festival with Binghamton and Bouwerie? Or the Harvest Home Tour with Binghamton and the Harridans? Don't make me go back and check, OK? They happened. They were fine.

This past weekend was the Foggy Bottom Morris Men's 30th anniversary celebration. Originally there were going to be seven BMM dancers going, and one musician, but then one dancer realized he had a longstanding family commitment the same weekend and another found out his wife's mother's husband or some quasi relation like that had about two weeks to live and another decided his plantar fasciitis was too severe for dancing and we were down to four of us. Meanwhile the Bouwerie Boys had only five dancers and no musicians able to go. So we went and helped each other out, since we have repertoire in common and have danced together on the ATM and at the Garlic Festival for years.

Also present were, let's see, Rock Creek, Charm City, Shepherdstown, Hicks With Sticks, Juggler Meadow, Wake Robin, Kingsessing, Mason-Dixon, and, all the way from Seattle, Mossyback. Did I leave any out? Probably.

I drove to Binghamton and met up with Ken, Bob, and Chris, and we all went from there in Ken's van. It rained the whole way down -- six hours from Binghamton, arriving midnight -- a miserable trip. But Saturday morning the rain stopped and we had great weather from there on.

The Saturday tour started in Relay, near Baltimore, at Clipper City Brewery. There was a brewery tour which I opted out of. Having toured numerous breweries in my time and two in the past year, I decided I'd rather stay in the pub. I'd bought tickets for six "samples" for $5, expecting samples to be a couple ounces, but no: about a half pint each. I only used four of my tickets and was well buzzed at that, before noon yet, especially after the Storm Watch at 7 point something percent alcohol. Good beer, generally, though the pirate-themed marketing made me cringe. Along with the sample tickets I got a free beer glass. Best five bucks I've spent in ages. I spent another ten on a discontinued long sleeve tee, because I love long sleeve tees (size XL) for sleeping in but rarely find them for a reasonable price.

From there we went to Fells Point and danced in the square and outside various pubs. Lunch was at Bertha's, as in Eat Bertha's Mussels. Then back to Relay for a feast at the Town Hall.

Sunday's dancing was in Washington, starting at Union Station and continuing at, do I have this right? Freedom Square, where we danced an enormous Chipping Campden Country Dance. We had a beer at the Elephant and Castle and then started the trek home -- among the first to leave, but we had a long trip and most of us were working Monday. Fortunately the drive back was considerably more pleasant than the drive down.

I had my worries about the weekend, given the distance and the paucity of numbers for our team, but it turned out I had a great time. We danced well, and we saw some excellent dancing: I was particularly taken by the solid, tight, and energetic performances by Rock Creek. And it was great seeing some faces (heck, entire bodies) I haven't seen in years.

Heather's mom (Sue) and Sue's boyfriend (Al) have been in New York this past week or so, and today we and they and Heather's sister (Rachel) and nephews (Mitchell and Sam) drove to Utica, boarded an excursion train to Forestport, ate lunch there (with birthday cake), took the train back to Utica, and drove home. I've never been much for leaf peeping but it was a pleasant day trip. Weather was ridiculous: 76 F, sunny. I'm just waiting for a rerun of last year when warm weather kept the Great Lakes warm until mid January, and then abruptly colder air switched the lake effect machine on. Fortunately, as of Tuesday, we no longer own a house in the worst of the lake effect area, and we no longer have a 35 mile commute each way.

I'm getting some CDs from Amazon, courtesy of Sue and Al. Kenny gave me a castles calendar, and Heather says now that I've taken up knitting she no longer has to puzzle over what to get me. She gave me 25 skeins of yarn.

Friday, to celebrate the house sale, I splurged on a new paper towel holder. Saturday I bought a refrigerator.

Saturday we also bought six pecks of apples, a gallon of maple syrup, and about 15 or 20 pumpkins.

At a garage sale today I picked up this:

I had a mechanical calculator similar to this when I was a kid, one with I think more digits. You enter numbers with a stylus to add and subtract. With my old one if you wanted to multiply or divide you were basically out of luck. This one can do it though. How? Flip it over and...

There you go.

Okay, a Curta it ain't, and I'm sure K&E lost no sleep over this thing, but for fifty cents I figured I'd take it home.

Twisted

2007-10-20T01:28:22Z

jwgh and I were chatting about knitted Möbius strips recently. There are several ways to knit a Möbius strip; despite the assertion of this page and other writings, making a mistake in joining up after casting on to circular needles is not one of them -- that produces a strip with one twist (or an integral number of twists), not the half twist that a true Möbius strip requires.

The easiest way is to knit a flat strip and graft the ends together, putting a half twist in. Maybe too easy. Not that satisfying, it seems to me, and it does have a true defect: the single edge you end up with is half cast on, half bound off. Nicer to have a strip whose edge is the same all around.

A harder way involves casting on, picking up stitches from the "non working" side of the cast on, and then knitting outwards in both directions; the cast on "edge" becomes the middle of the strip, and the edge is 100% bound off.

What occurred to me in thinking about it is that there's another way (and no, I don't claim I'm the first to think of this... only that I did think of it): If you cut a Möbius strip down the middle, you end up with a single loop with two twists, right? And we know how to knit one of those -- I mentioned it above: cast onto a circular needle and "make a mistake" joining up, i.e. put two twists into the stitches first.

Well, if cutting a Möbius strip down the middle make a double-twisted loop, and if we know how to knit a double-twisted loop, then we can knit a Möbius strip by knitting a double-twisted loop and instead of binding off the terminal edge, grafting it onto itself, right? This is kind of the reverse of the second method -- the cast on edge provides the edge of the Möbius strip, and the terminal edge (the one that would have been the bound off edge, had we bound off) becomes the center.

Maybe someday I'll knit a scarf like that, but for now, I just wanted to prove the principle, so I did a quick and sloppy job of casting on 60 stitches, knitting about 6 rows, and grafting it together. I've never done Kitchener stitch before, and I guess I did it wrong -- it doesn't match the garter stitch, in fact it came out as stockinette which of course doesn't work well on a Möbius strip. Still, I think I've proved the idea is sound.
