  • Don’t forget the annular solar eclipse that will touch the Southwestern US this Sunday, May 20.
  • From the Words-I-Didn’t-Know-Until-Yesterday Department: Ignorosphere, the region from about 120,000 feet altitude to the lowest stable orbit. (It’s a flip term for the mesosphere.) It’s too high for winged aircraft or balloons, and not empty enough for orbiting spacecraft. Sampling it is difficult (one-shot sounding rockets are all we have in terms of tools) and we know less about it than any other region of near space.
  • After a long conversation on the subject with mobile developer David Beers the other day, I stumbled on an article that drives home the problematic nature of Android app development: There are actually four thousand different Androids. (Maybe more.)
  • I’m seeing more and more videos in, um, bad taste being posted to my friends’ Facebook feeds by something called Socialcam. The suggestion is that those who post have actually viewed the videos, but that’s not true. Socialcam reserves the right to post stuff to your Facebook feed that you have not viewed and have no knowledge of. Tear that damned thing out by the roots.
  • This certainly makes me wish that I liked corn more than I do.
  • An interesting study here adds fuel to the fire over suggestions that keeping a consistent sleep schedule helps you lose weight. I.e., don’t try to “make up” lost sleep on the weekends. Doesn’t work. I’ve been saying this for years, based on a lecture series I took at the Mayo Clinic: Getting five hours of sleep a night will make you fat and kill you before your time. People get angry at me for suggesting that they be in bed, lights-out, between 9:30 and 10 PM if they have to get up at six to get to school or work, but that’s probably what it takes. A handful of people may be able to get by on five or six hours a night. The usual human-traits bell curve suggests that you are almost certainly not one of them.
  • If you remember a speculation I made some time back about dogs and human origins, well here’s another: That dogs helped us drive the Neanderthals to extinction. I’m dubious. My sense is that their lack of dogs allowed the Neanderthals to drive themselves to extinction via dawn raids. Dogs made dawn raids difficult, and so we failed to wipe our own species out. (I haven’t seen any evidence yet that Neanderthals kept dogs, but of course I’m still looking.)
  • If you don’t know what a “zoetrope” is, go look it up before you behold the pizzoetrope, which is essentially an edible animation created by spinning a pizza. Sounds loopy (as it were) but it works.

  • Not posting often here, but I’m ok. Working hard on several things, chief of which is getting my office and Carol’s exchanged, outfitted, and fully functional. This involves furniture, wiring, lighting, and sorting an immense quantity of glarble. I hope to return to regular in-depth posting soon.
  • I have a new favorite cheese: cave-aged gruyere, which can be had sometimes at King Soopers, and is lucious with a good dry red wine. Get the oldest cheese you can find, as young gruyere tastes nothing like old gruyere. A year is as young as I buy.
  • The asteroid that whacked the dinosaurs must have thrown an immense amount of material into space. How much rock might have made the journey, and how far far did it go? Here’s a good quick take on the topic. It would take a million years or more to get to Gliese 581, but suitably rugged bacterial spores might have survived, and made the origin of life on planets there unnecessary. (Thanks to Pete Albrecht for the link.)
  • A book I’m not bullish on: Steven Johnson’s The Ghost Map, which describes how the cause of cholera (infected water) was proven by the persistent John Snow through charting of cholera deaths upon a map of London neighborhood water pumps. Why? The book does not include the actual ghost map named in the title. (So what else is missing or wrong?) Whatever editor let that past should be fired and spend the rest of his/her days stuffing toddler clothes in racks at Wal Mart.
  • Could the TRS-80 Mod 100 possibly be 30 years old? Yes indeedy, and it was ubiquitous among tech journalists when I was at PC Tech Journal in ’85-86. Its keycaps made a distinctive sound, and sitting in a significant press conference back then was like sitting under a tin roof in a rainstorm. I yearned for one myself (the keyboard was wonderful for such a small device) but didn’t pull the trigger because the machine did so little other than keystroke capture.
  • Toward the end of my tenure at Xerox I saw the Sunrise, which was a more ambitious take on the “lapslab” concept. My department was considering writing an app for it, so I had a loaner for awhile. Even better keyboard than the TRS 100, cassette data storage, modem…but the 3-line display was harder to read. Xerox private-labeled the hardware from another company, and basically killed it with a $1500 price point. (There was a flashier version that cost…$2500!) Xerox abandoned the market in 1984, after sinking what rumor held to be an obscene amount of money into it.
  • One machine I did consider was the Exidy Sorcerer, which also had a good keyboard and didn’t cost $3000. Lack of software made me spend the $3000 anyway, on a huge honking S100 system running a 1 MHz 8080.
  • One of the big issues between Amazon and the Big Six is an explosion of co-op fees, which according to some reports have increased by 30 times since 2011. The whole “co-op” business has always smelled gamey to me, but it had a purpose in the B&M bookselling world. How it fits into online ebook retailing is less clear, and in my view starts leaning perilously in the direction of bribery.
  • Most of us think that reading is in decline. Gallup poll results suggest otherwise. Nor are today’s books worse than those of 40+ years ago. This quote is significant: “The bad [books] of yesteryear have gone out of print while the bad ones of today are alive and being sold in supermarkets.”
  • I’m still watching the ASUS Tranformer Prime (their botch of its GPS support has kept me away for the time being) but the Prime has a little (as in cheaper) brother now, and it looks like a decent machine in its own right. Here’s Engadget’s detailed review of theTransformer Pad TF-300.
  • Here’s another wonderful gallery from Dark Roasted Blend, this time of high-speed photos of liquids. Some of it is photoshopped, but it’s all startling. (Thanks to Ernie Marek for the link.)
  • Santorini is smouldering again. Yes, the volcano that may have made the Minoans extinct and launched the legend of Atlantis (or at least put an older legend on the map) is getting restless. Like the Greeks need that right now.
  • Eating meat allowed our hominid ancestors to reproduce more quickly, by accelerating infant brain growth and thus shortening the breastfeeding period. (Breastfeeding naturally inhibits ovulation.) This on top of several other issues.
  • From the Words-I-Didn’t-Know-Until-Yesterday Department: Beatboxing , which is vocal generation of sounds like drums and synthesized sound effects. I heard of this in an interesting way: There’s a slightly silly commercial for the Honda Pilot that involves a Pilot full of bored tweens beatboxing the rhythm of Ozzy Osbourne’s “Crazy Train,” and by chance we had captioning turned on. When the kids started making noises, the captioning read, “Beatboxing.”
  • Pete Albrecht sends a link to a map color-coding US gas prices by county. The very abrupt differences between states suggests that gas prices are more a question of state and local taxes than regional differences in demand.
  • It was inevitable: A 3D printer that prints chocolate novelties. Now we need a 3D printer that prints spice-cake Easter lambs with ears that stay on.

  • I’m behind on a great many things, especially fiction writing and replying to email, so bear with me until I get dug out from under the pile. Exchanging offices within a house is precisely the same as moving two offices, and that means a lot of boxes and a lot of bother, exploding intercoms being the least of it.
  • I didn’t expect this wine to be as good as it actually is. About $11.
  • The weather’s been beautiful here, so yesterday I was going to get out on the back deck with my Icom 736 and work the world. That was, of course, the day that sunspots basically vanished on the visible face of the Sun. What does it mean to have solar flares but no sunspots? Nobody knows.
  • Thanks to many people (Jim Strickland being the first) who wrote to tell me about a “smart sand” project at MIT that is the first step toward the sort of nanoreplicator I postulated in my Drumlins stories: Tap in a 256-bit code, and some “smart dust” (very smart) in a stone bowl assembles something for you. I love it when my crazy dreams come true!
  • Single-atom nanotransistors can now be reliably made, rather than hunted for. (Thanks to Roy harvey for the link.)
  • From Michael Covington comes a link to a fascinating article about the other kind of abduction: abductive logic. If you’re a Sherlock Holmes fan, don’t miss it!
  • The Colorado state law that led Amazon to nuke my Associates account has been declared unconstitional. No word from Amazon as to whether I can have my account back.
  • I would probably buy one of these if I could find one in stock somewhere.
  • Jack Tramiel has left us, having created quite a raft of famous computers, including the very best forgotten computer ever.
  • I checked the date on this one, but it was nine days too late to assume it’s a hoax. One might argue that solar panels are more elegant, but you can’t make buffalo spaghetti sauce in a solar panel.
  • I’ve seen more dumb YouTube posts than I’m willing to admit, but this one takes the cake for sheer willful stupidity. I knew how this worked in 1959, when I was 7.
  • Kids, this is futurism. All we need now are better tacos.

  • 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.)

  • I was wrong about Diesel engines being easy to make, as I suggested in my entry for March 5, 2012. Fuel injection, as it turns out, is a bitch. You’re trying to divide oil into a multitude of very small droplets of (reasonably) consistent size. Gasoline carburetion, by comparison, is a snap. (Thanks to Pete Albrecht, an automotive engineer, for the reminder.)
  • I suspect it’s easier to produce wood gas (AKA “producer gas”) at a small scale than gasoline. In a future where large-scale oil refiners are no more, a Dieselpunk society could power internal combustion engines with wood gas. This has been done a lot around the world, especially during WWII when oil supply channels were disrupted.
  • This has little or nothing to do with the Holy Roman Empire, but if you’re a map freak, boy–budget a day for it. Wow.
  • This looks like a good book, especially if you’re finding it hard to keep track of genre mutation within SFF. Will order and report after reading. (Thanks to Trudy Seabrook for pointing it out.)
  • We found one of these in a drawer in my late grandfather’s workbench after my grandmother died in 1965 and we had to sell their house. I never knew what it was until it made the A-head story on the front page of yesterday’s Wall Street Journal , in an article about…olympic sheep shearing. My grandfather lived a quiet life in a modest house on a tiny lot on Chicago’s north side. There wasn’t a sheep for miles. (I hope he didn’t use it to cut my father’s hair.)
  • I’ve noted some confusion about this: “Retina display” is not an Apple trademark, but a technical term: a display with such high resolution that the eye can’t make out individual pixels at typical reading distance. Here’s a good explanation of the whole retina display concept. The new iPad certainly qualifies, but it wasn’t the first. Asus’ Tranformer Prime was there some time ago. Retina-quality displays are made by several vendors, and will eventually appear in other high-end tablets.
  • The Lytro camera has been mentioned in a lot of places, but here’s the first in-depth description I’ve seen. A camera that allows you to fiddle with the focus after the shot is taken is FM, if you know what I mean. I ditch about a third of my digital photos (mostly taken in bad light) for focus problems. It’s an awkward form factor, but if it’s the first of it’s kind, I’ll assume the next one will fit the hand a little better.
  • The mad scientist in me cried out when I saw this. I need a castle. I need a kite. I need a monster.

  • For the several people who asked: The odor-free carpet pad that we used in carpeting the lower level here is called Napa Carpet Cushion, from Leggett & Platt.
  • Apart from N&P’s Fallen Angels, Bob Tucker’s Ice and Iron, and possibly Mackelworth’s Tiltangle, what other SF novels involve an ice age on Earth in the near(ish) future? I have a concept that capitalizes on all my recent paleoclimate research, and I’d like to see if it’s already been done.
  • Whoops, found a list just before posting this. I clearly have some reading to do, assuming I can find any of these items. What are your personal favorites?
  • Today’s sunspot number is very close to zero. I haven’t seen sunspot activity this low in some time, and here we are supposedly barreling into the Cycle 24 maximum. The sunspot number is going in the wrong direction. 6M DX is evidently not in my immediate future.
  • Joe Flamini and Jack Smith are both pretty sure that the mysterious Comco gizmo I presented in my February 6, 2012 entry is an early remote control unit for commercial and public service radio systems, allowing control of a transmitter or repeater through leased phone lines. More on this in a future entry.
  • Having read briefly about hydraulic analog computing in a magazine decades ago, I built hydraulic calculators and computers into the technological background for my novel The Cunning Blood. Turns out the Russians did it on a pretty large scale back in the years running up to WWII. (Thanks to Jim Strickland for the link.)
  • From the You-Probably-Couldn’t-Do-That-Today Department: The flipside of the Chad Mitchell Trio’s 1963 hit kid/Christmas 45 “The Marvelous Toy” was “The Bonny Streets of Fyve-I-O, about a colonel who shoots one of his own captains for insubordination.
  • Tucows (does anybody even remember Tucows?) is launching a contract-free mobile service using Sprint’s network. The rates are interesting, and favor people who want smartphones but just don’t use them much, and data little or not at all.
  • The Maker Shed has a $99 Geiger counter kit that allows logging of pulses through a serial port, and detects both beta and gamma radiation.
  • A little gruesome maybe, but it’s real: When we lived in California in the late ’80s, there were reports of sneakers washing up on Santa Cruz area beaches…with human feet still inside them. At the time we assumed drug violence, but there’s a less scurrilous if no less ghastly explanation for a phenomenon that’s still happening. (Thanks to Pete Albrecht for the link.)
  • Mmmph. Military combat aircraft should be able to fly in more air than we’re used to, no? Sweden had this problem recently. (I’m guessing that Saab has it too, now.) Thanks to Aki Peltonen for the link.
  • The name of my company, Copperwood Media, LLC, was inspired by a set of traces on an old PCB that just happened to look (a little) like a tree. I had an artist draw me a better copper tree for the logo, way back in 2000. Now Rich Rostrom sends a link to the odd tradition in some parts of the UK of hammering coins into cracks in trees until the notion of “copperwood” takes on a whole new meaning.
  • Some very nice steampunk watches and jewelry. “Chronambulator” is a great word, whether or not you’ve got a steampunk gizmo to hang it on. Note also the level-reading absinthe hip-flask. (Thanks to Bill Cherepy for the link.)
