No Supinator for You!

On Wednesday I hurt my left arm, and am still typing one-handed. Carol (who is a physical therapist) tells me that I may have pulled my left supinator. I didn’t even know I had a supinator, which to me sounds like a brand of crockpot. Whatever a supinator might in fact be, I know by now that it hurts like hell when mistreated.

Bottom line: I may not be doing much posting for the coming week. Lesson: I am 59, not 19. I cannot throw boxes full of books around with the aplomb I once exhibited. I would like to get my aplomb back, but like my hair, that train may have left the station.

I’ll be back when I can use my left hand again.

  • Movers are coming imminently to reassemble my lower level, so I will be mostly out of touch for the rest of today.
  • If you’ve never had an account with Verizon in the past, don’t get one now. Verizon sold a huge number (over a million!) of expired debt accounts to a debt collection agency called AFNI, which has been attempting to collect on some of them, even when the debt has long since passed over the horizon of the statute of limitations. Some of these debts were long since paid off, some were mistakes, and some may possibly be complete inventions. Verizon’s action was legal; AFNI’s may not be. Still, Verizon started it, and I’m encouraging people not to do business with them.
  • Here’s an aurora prediction site I’d not seen before. We’re a little too far south to get much from the current outbursts, but having seen some of the 2005 auroras here (if barely) I’m certainly watching that red line. (Thanks to Jamie Hanrahan for the link.)
  • From the Words-I-Didn’t-Know-Until-Yesterday Department: A tuya is a volcanic landform created by a smallish volcanic eruption that occurs under a kilometer-class ice sheet, as from our most recent ice age.
  • Roy Tellason wrote to tell me about his tube data sheet page, which has more scanned data sheets (all PDFs; typically under 1 MB) in one place than I’ve ever seen, with no ads nor any fussing (registration, etc.) required to access them.
  • Rich Rostrom sent a wonderful link to a collection of photos and drawings of the Hindenburg, including its passenger areas, which included (egad) a smoking room! Originally (it was later expanded a little) the airship could carry only 50 passengers, tops. Those must have been expensive tickets…
  • I was starting to get this message almost fifteen years ago: Heart disease is about inflammation. It’s not about meat or fat. Inflammation comes from smoking, chemicals of various sorts, infections, and (most commonly) sugars and vegetable oils. No inflammation, no heart disease. (Thanks to Mike Bentley for the link.)
  • I’m shopping for vacuum tube intercoms, and found that someone on eBay has listed the Talk-A-Phone set that my parents bought (they were made in Chicago then) and used as a baby monitor after my sister was born. I’d really prefer one of the mid-60s tube-based carrier-current models. All the majors had them. (Carol wants a better way to reach me when I’m in my office than yelling down the stairs…)
  • The beautiful 1920s Des Plaines Theater has reopened after some major restoration, and is now slotting upscale live acts rather than movies. It’s literally around the corner from our Chicago-area condo, and I’m itching to find an event as an excuse to go in and look around.
  • If you’re afraid of spiders, don’t go to Australia for awhile. (Thanks to Pete Albrecht for the link.)
  • Dinosaur fossils don’t get a whole lot better than this.
  • While doing my semiregular scan for pirated copies of my books, I happened across something fascinating on alt.binaries.e-book.technical: a scan of the original service manual for the Nazi V-1 flying bomb. I don’t know how to create an NZB that points directly to the file, but the item was posted on 10/25/2011. Search for “Gerate-handbuch FZG-76”. A dieselpunk pulse-jet is what it was, and now you can see what was inside it. (Being able to read German is a plus, but the photos are very good.)
  • A wonderful photo collection of vintage ice-cream trucks. We saw the Good Humor trucks regularly on our street in the 50s and early 60s. The driver rang bells by pulling on a string. He did not play obscure hymns or creepy recorded voices saying “Helllo!”
  • How’s your scene? (I had to look it up to see what a “scene” was in this context.) My “scene” is not listed, but you can see what the chap thinks of steampunk. And if you want a timeline, it’s here. (Alas, it starts in…2000. Do you feel mondo-creaky old looking at this? I do.)

  • Happy Thanksgiving Day to all who celebrate it–and to those who don’t, well, this guy is still thankful that the world is big enough for both of us. In terms of Thanksgiving Day meditations, I’ll simply offer the one I wrote in 2008. I may not ever do better than that.
  • From the Words-I-Didn’t-Know-Until-Yesterday File: seedbox, a remote and generally headless system on a high-bandwidth Internet connection, used exclusively to seed torrents in defiance of ISP speed-throttling of BitTorrent users.
  • Also pertinent to yesterday’s entry: Penguin Books got into a snit of lender’s remorse, and basically shut down access to its titles previously available to public library patrons through Amazon’s Kindle lending program. Apparently the DRM wasn’t DRM-y enough, and Penguin (through the Overdrive technology) locked its titles out. Precisely what the technical issues are is still unclear, but I’m researching it.
  • We have lost Anne McCaffrey, at age 85. She died of a stroke at her home in Ireland on November 21. She was the first woman to earn a Hugo or a Nebula award, and did a great deal to drag SF out of the locker room to which the pulps had led it.
  • Having recently become an Android user (via my Droid X2) I have now begun to dream of SparkFun’s Electric Sheep.
  • Debsnews now has a wine channel. It’s one way to focus in on specific short videos (example: WalMart’s new $3 wine line) without having to spend a third of your life parked in front of a TV.
  • Anybody who’s tried to spread a Ziplock bag with one hand while pouring leftover spaghetti sauce into it with the other may appreciate this gadget. Everybody else, move along.
  • Many people are sending me links to stories about canned goods containing greater than acceptable levels of BPA. This is not new news. However, I didn’t know about it until yesterday, right after opening a can of Spam.
  • Maybe the new Spam Singles packaging is the answer. No can!
  • Carol met Colonel Sanders at the Mayo Clinic back in 1975, and the guy does get around. You can now see him from space. This is not photoshopped, but the real deal. It’s been there since 2006, and consists of 87,000 colored tile “pixels.” (Thanks to Frank Glover for the link.)
  • Make describes a steam-powered bristlebot. Somehow this reminds me of those little scrubbing-bubble guys on the TV commercials.
  • There may be another reason (quite apart from battery life) to turn your smartphone’s power off every night. (Thanks to Pamela Boulais for the link.)
  • If you’ve never gone up to the Car Talk Web site and looked at the staff credits page, you’re missing out on people you haven’t seen since your study hall attendance-sheet days. (Thanks to Pete Albrecht for the link.)

Talking About Con Crud

I’ve been quiet here in part because Carol and I bought new smartphones on Saturday afternoon: a pair of Droid X2 units with which we are (so far) completely delighted. That said, I’ve discovered that research into the Dalvik VM and bytecode set does not help you learn how to move icons onto your Android desktop. Smartphones don’t come with manuals in the box anymore. Preston Gralla will sell me one on October 5. Until then, my learning process will consist of mildly Web-guided poking around.

More on this later. In the meantime, Michael Covington recently reminded me of a phenomenon I had not thought about in some years: con crud. Basically, people who go to SFF or media/gamer cons often come home with a nasty cold that sometimes borders on flu. Con celebrities have taken to refusing handshakes and hugs for fear of catching it (PvP guru Scott Kurtz is one) but nobody seems to agree on what-all causes it nor how to avoid it.

I’ve gotten con crud more than once. Interestingly, it wasn’t always at SFF cons. I came down with a nasty case after the 1983 (I think) Trenton Computer Festival. And the mother of all con crud episodes for me was a computer trade show in 1992, at which I came down with a bad case of bacterial pneumonia after three days in the PC Techniques show booth. It took some heavy-duty antibiotics and a week flat on my ass in bed to become functional again.

While there’s little agreement online as to causes, there are statistical bumps in the discussion on the following points:

  • Not enough sleep. Staying up all night is a form of recreation in itself.
  • Physical contact with other people. Hugs, not drugs!
  • Bad food. People eat sugar and fat at cons. (Never at home, right?)
  • Poor personal hygiene. We’re having too much fun to shower!

Sleep is certainly an issue. When I don’t sleep enough, I get sick. I have noticed that (within my own circles) morning people are generally healthier than night people, and among those I know well enough to ask, night people get way less sleep than morning people. There are of course causality questions here, but I think I can say confidently that the con crowd is dominated by night people.

The notion that fat and sugar suppress your immune system, and the flipside that fruits and veggies and whole grains strengthen it, is unproven and probably nonsense. (If it were true I’m sure I’d be long dead.) Skipping meals entirely may be more of an issue here. Hugs and handshakes may put some loose viruses on your skin, but breathing other people’s air is probably a more potent vector, and anybody who works in a big company cube farm is breathing other people’s viruses at con-scale all day, every day. Poor personal hygiene is an issue, though it may be as simple as not washing your hands as much as you do in mundane life.

I do have a suggested cause that I have not yet seen online: talking too much. Some people talk for a living. Most people work and study largely in silence. Then they go to a con and spend three days and three nights talking almost continuously. By the end of Day 2 of booth duty at early Coriolis show booths I generally felt scratchy in the throat, and when the whole thing was done and over I could barely talk at all. Basically, when you shred your vocal cords all weekend, you provide a stressed environment in your throat that’s easy prey for microorganisms. Not sleeping may then be enough to push you over the edge into serious infection.

If this is true, there’s no easy way around it. Cons are social gatherings, after all, and the real draw are not the exhibits or conference sessions but all the interesting people. My prescription will get some people angry but I think it will work: Talk all you want, but be in bed by midnight and sleep until 9:30. Try it. Let me know if it works.

  • Does anybody here use true peer-to-peer chat? I don’t use chat much, and when I do it’s with a very small number of people, typically one-to-one. By peer-to-peer I mean via direct connect from one IP to another, without intermediation at the server level, as with things like Trillian, Skype, Jabber, etc. I know that WASTE does this, though I’ve never tried it. What else might work? I don’t want to mount a new server if I can avoid it.
  • New research suggests that low-salt diets increase insulin resistance–and thus propel otherwise healthy people toward diabetes. (Via Fat Head.)
  • More on Amazon’s rumored Android tablet. Print Replica (as I discussed in yesterday’s entry) has almost nothing to do with it.
  • Note well: Sony’s new tablet is not really sideload-able, since the device cannot render content directly from an inserted SD card. You have to copy all material from the card to internal storage. Also, the weird cross-section makes it almost inescapably a landscape machine. No thanks.
  • Interesting short piece on the other Delphi–as in, Oracle of.
  • For those who asked: The 400W power supply I just bought for my Core 2 Quad is the Antec Neo Eco 400C. So far…love it!
  • Having sold out all the TouchPads there were at fire-sale prices, HP now intends to…make some more. Something flaky here: Lose a little money on each sale, and make it up in volume? Doesn’t add up…unless it was a slick and risky attempt to build a demand base.
  • Didn’t know this before: Setting a .jpg to quality setting 7 in Photoshop degrades the image’s quality. Stay at 6–or bump to 8.
  • How about Han Solo Carbonite Slab ice cubes? Brilliant gimmick, though I wonder (given that the product is marked as “unavailable”) if they’re really out of stock or just didn’t close the deal with Lucasfilm.

Paradoxical Insomnia

For all the time I’ve been struggling with insomnia, I had never heard of “paradoxical insomnia” until Michael Covington recently called it to my attention.

Sleep is a weird business from top to bottom. I’ve encountered a lot of that weirdness, especially since 2001, when my company began to implode. I’ve never been a strong sleeper, but after that I began having nights when I might sleep for no more than an hour…

…or so it seemed at the time.

One of the weirdnesses of the post-Coriolis era is that, for as little as I thought I slept, I seemed to do reasonably well during the day. I certainly wasn’t at my best, but for the most part I wasn’t falling asleep in my chair. I wonder now if I experienced paradoxical insomnia, which is an unusual sleep disorder in which patients feel like they have slept little (or not at all) when in fact they slept adequately, if not normally. In paradoxical insomnia, a patient perceives time spent awake incorrectly. He or she might feel like it takes an hour or more to fall asleep when in fact it took only a few minutes. Early-morning awakenings during which hours seem to pass may again span only a few minutes. The condition is poorly understood. Researchers now think that patients are dreaming that they’re awake. This may seem bizarre to people who sleep normally, but let me tell you, I understand completely.

Here’s why: In my case, at least, the border between wakefulness and dreaming is rubbery. I’ve had some success with a technique I read in one book or another, which involves imagining some quiet activity that reflects daily life. Counting sheep may work for people who live and work with sheep. I’ve seen live sheep half a dozen times in my life, and you can have ’em. What works for me is imagining things like taking walks, sorting books on bookshelves, and having boring conversations with unexceptional people. Although I have “interesting” dreams about one shot in ten (along with the very occasional lulu) the vast majority of my dreams are very much like that: walking alone or sometimes with a nameless companion, or doing domestic things of little consequence, like taking towels out of the washing machine and putting them in the dryer.

I know that the technique works because a time or two I recall sliding from guided meditation into a dream without any change of scenery. I know that it was a dream because it stopped following the script. Here’s the best example: Jeff and a nameless and poorly imagined female companion are walking down a country road on a generic summer evening, talking about dumb stuff. No mosquitoes.

JEFF: Hey, there’s a sycamore tree! I like sycamore trees.

COMPANION: Me too.

JEFF: My grandfather planted one in the back yard when I was a kid. It had the biggest damned leaves.

COMPANION: I remember those.

JEFF: And seed balls. We used to throw them at each other.

COMPANION: That must have been fun.

JEFF: It was. We used to be able to burn the leaves in the street.

COMPANION (Turning): Jeff, what do you want most from God?

JEFF: Unconditional love.

Bzzzzt! In my directed meditations my imaginary companions do not ask me questions. So when my imaginary companions begin taking control, I know (in hindsight) that I’m dreaming.

In the grim days after Coriolis went under, I had plenty of experience lying awake much of the night and staring at the wall. At some point it became part of ordinary life, and thus completely unremarkable dream-fodder. I also seem to slide from conscious thought into dream states very smoothly. This is why dreaming about lying awake is no stretch at all, and may have continued long after I had gotten over the loss. It may continue to this day. Short of monitoring my own brain waves, I’m not sure how to tell.

But boy, it’s probably better than talking beavers.

  • Freedom matters, and in honor of Independence Day here’s an eye-opening report on the “state of freedom” in the fifty American states. I knew a lot of this from my research nine years ago, when Carol and I decided to leave Arizona, but it’s nice to see it all in one free (in the other sense) document.
  • From the Words I Didn’t Know Until Yesterday Department: draisine, a human-powered device for moving over railroad rails. This is evidently a European term; over here these are called handcars or inspection speeders or rail cycles or a number of other things. Definitely note the hot-pink draisine-built-for-two on the Wikipedia page. (Thanks to Aki Peltonen for dropping the word to me.)
  • Although I’m sure that everyone in the civilized galaxy has seen the cartoon, I wasn’t aware that “thagomizer” is now paleobiological jargon. (Thanks to Pete Albrecht for the link.)
  • Here’s a list of somebody’s picks as the ten best hard SF books of all time. I agree with about 50% of the picks, though Robinson’s Mars trilogy was so slow and padded-out that I could barely finish it. (I have not yet read the Egan book cited.) I sense as well that Somebody Doesn’t Like Heinlein’s Politics. (Thanks to Frank Glover for the link.)
  • Despite a 500-fold increase in cell phone use in the last 20 years, malignant brain tumor diagnosis is down in that timeframe. This interests me, as three people I knew died of brain tumors (the largest cancer cluster in my circle of acquaintance) and it makes me wonder. (Thanks to Pete Albrecht for the link.)
  • I had just a couple of comic books back in the early Sixties, and one of the most intriguing was an extra-long number from DC called Secret Origins that had the backstory for five or six of the most famous DC superheroes. Oddly, what I remember most clearly was the backstory for Green Lantern, especially the little blue guys on the Planet Without Consonants and (most intriguing of all) a power ring with a flaw that prevented it from working against anything yellow. Trouble is, if you remove the flaw, the ring loses its power completely. Now that’s cool–alas, in what may be the canonical Green Lantern for Dummies page, the yellow gotcha isn’t stated clearly and I wonder if it was just abandoned back in the 1960s.
  • Forgot to aggregate this back in January: One of the most bizarre articles I’ve ever read on any major site in recent years. This totally, completely, utterly certain guy is angry at other guys for being totally, completely, and utterly certain–and that about something totally, completely, and utterly trivial. My take: We “know” nothing at all with certainty, and the more certain you are that you’re right, the more certain the rest of us should be that you’re wrong. Nyah-nyah!
  • And another Odd Lot that has lain around for some time: Polish troops trained a young bear to carry ammo during the Battle of Monte Cassino. My father was at that battle, working a radio station on the back of a truck, but he never mentioned seeing the bear. The bear is said to never have dropped any munitions, which I’m sure was a good thing for the bear, and possibly my father as well.
  • Here’s a bogglingly weird Dickensian artifact that I’d never heard of before: A key gun. It’s a gun built into the key to a (large) prison cell lock. I’m sure if it had worked better I would have seen it before now.
