I hate computers

I've been mucking around for hours tonight trying to get Windows file sharing to work between the three computers here, and all I've managed to do is break it worse. (The one thing that used to work was that the winxp machine could see the win95 machine (not vice versa), but now nobody can see anybody.) Grr.
What distressing is I have no idea even what to try from this point, besides setting the workgroup name back and seeing if that returns it to the old broken state.

can anyone explain chocolate?

It seems to exist in at least two different solid phases, "solid tempered" (dark and shiny) and "solid untempered" (tan and crumbly). Descriptions of the tempering procedure suggest that liquid tempered chocolate is stable between 83 and 95 °F, while untempered chocolate is solid up to 115. When it melts (into untempered liquid chocolate?) it can be converted to liquid tempered chocolate by adding chunks of solid tempered chocolate. (By rapid cooling? Or one recipe says it's seeded crystallization; I could buy catalysis anyway.) Or by cooling with stirring, apparently. But I've certainly seen that cooling by letting it sit out leads to untempered crud. On the other hand, we know liquid tempered chocolate can cool to solid tempered chocolate -- maybe when it's cooled faster?

What are the thermodynamic phases reached in cooking with chocolate? I wonder if the tempered solid phase is only metastable. I guess I want a phase diagram that also sketches the metastable regions.

Suzanne Vega concert

She's no Jane Siberry :), but it was fun. Crowded -- too big for Rosebud, really, people standing all in the margins -- but one of the advantages of going solo is scamming a left-over good seat.

I was happily surprised that album they played most heavily was her first -- played half of it -- which is also my favorite. Maybe she likes it too. Usually people would rather play their later songs (and I guess it's for a reason that they change what it is they write).

I was really floored, though, by the performances of some of the later heavier songs: "When Heroes Go Down", which had never really grabbed me until this, and "99.9 °F", which was always a good song, but here got a flat-out performance with some fine electric guitar.

She said, to a request for "Solitude Standing", that (ironically) she had never arranged/practiced it for solo performance or for this band. I wonder if that applies to other stuff from that album, which it occurs to me now didn't show up much. "In the Eye", "Night Vision", and (ooh) "If Language Were Liquid" would have been great to hear live. And "Caspar Hauser's Song" is, for some reason about the tone of her voice (and the what sounds like heavy Aphex all over through the album), the most blankly despairing song I've ever heard. That's a compliment.
