Odd Lots

  • While chasing an interesting “out of the blue” idea that came to me while exercising the other day, I happened upon an RV surplus shop. Not surprisingly, it's in Elkhart, Indiana (Ground Zero for the American RV industry) and it sells leftovers and overstocks of RV parts and interior furniture. If I were to want to built a custom RV dinette table with a built-in keyboard, well, this might be the place to start.
  • Good grief: Has Big Media run out of Republicans to torment? ABC News posted this story about the pastor of Obama's Chicago church, who repeatedly condemns the US in his sermons and tells his people that they should be singing “God Damn America” instead of “God Bless America.” Expect those sermons (which are offered for sale by the church) to become very popular in coming months.
  • Illinois is famous for a lot of things, but being the historical capital of manufacturing of fraternal organization initiation and hazing equipment is not one of them. However, the De Moulin Company of Greenville, Illinois, now known for making band uniforms, used to do a big and almost unimaginably bizarre business manufacturing expensive gag items used to make new Masons and Elks feel like one of the gang. The precise psychology here is obscure to me (the last remotely fraternal organization I joined was the Boy Scouts) but the devices are just insane. Browse and boggle.
  • Here's another source for home-made telescope optics and truss telescope kits up to 32″ in clear aperature. Even though I'm not a big Dobsonian fan, the scopes look good, and if you want light-gathering power above all else something like this is as good as you're going to do short of a full-concrete observatory. The optics are not cheap, but they're good. (Thanks to Pete Albrecht for the link.)
  • Also from Pete comes a link to a site selling Swiss Army Ohmmeters. Should the Swiss Army encounter resistance, well, they'll be ready.
  • Mike Burton (who worked in the industry for some time) wrote to say that “double shot” keyboards are no longer produced due to their expense. A double-shot keyboard is one in which the keycaps are molded in two steps: One step to mold the body of the cap, with a void in the shape of the letter, and a second to fill the void with black plastic. Such keycaps never lose their legends, like my decal-equipped Avant Stellar is now doing at great speed. I guess I had better stock up on period Northgates.
  • We have evidently found the gene that triggers the onset of puberty. One wonders what suppressing this gene would do long-term. What would be the psychology of a 75-year-old boy who had never gone through puberty? Larry Niven toyed with the idea in World Out of Time, speculating that stopping puberty would stop aging, but I intuit that much more could be done with it. Would I give up sex for a shot at becoming immortal? (Answer from this side of the fence: No. Ask me in 1962 and you might have gotten a different answer.) Much depends on whether emotional maturity is a process inherent in or only affected by puberty. Sooner or later some renegade will try this, and we'll know.

  • Do not fail to read Bruce Schneier's latest short item in Wired, which is his simple demolition of David Brin's peculiar “transparent society” concept, which I first read of in his so-so novel Earth (1990) and thought was BS even then. Having no secrets doesn't help where the differential of power between two parties is high. This seems pretty obvious to me; I do not understand why Brin gets points for this “no secrets” notion of his.
  • Some of the worst horror films (as well as SF films and some westerns) can be streamed without charge here. Where else can you find “Attack of the Giant Leeches” or “Killer Shrews,” both of which I recall seeing on Channel 7 at 4 PM on Thursdays back 1965-ish. Even at age 12 I could roll my eyes and say, “Those aren't giant shrews. Those are dogs in bad shrew costumes.” But hey, that's what makes a B-movie a B-movie, right?
  • It may be clever, but can a gun this small really be deadly? (That is, assuming you don't aim it up your left nostril…)
  • This is freaking amazing: Images of a landslide on Mars, taken while it's happening. (Thanks to Pete Albrecht for the link.)
  • Jim Strickland pointed out a pneumatic tennis-ball based antenna launcher. We always used slingshots back in the day, and I have a Greenlee Cablecaster that was designed for dragging CAT5 over suspended ceilings via fishline, but something about the ball shooter is very appealing.
  • Glover Wright is bringing back Science Fiction Quarterly as an online pub, and it looks promising. I recall reading a few ancient issues of the original SF Quarterly pulps from the late 50s and was pleased, though the world and I were, um, at least thirty years younger then. The first issue will be out in March.
  • Gripe of the week: The keycap letters on my expensive Avant Stellar keyboard are decals, and they are already wearing off. It's only been a year. What's this thing going to look like after another ten?
  • Speaking of keyboards: I need a wireless keyboard for use while sitting on the couch and running photos or video clips on our big TV. The SX270 is under the TV in plain view of the couch. The keyboard needs to have an integral pointing device. (I prefer things like IBM's TrackPoint nipple to the ubiquitous scratchpad.) Anybody got any suggestions?

  • I remember reading somewhere years ago that having a photo of a box on your Web store improves your sell-through of downloadable software, even if the product is never sold in a box and even if the box doesn't even exist. Anyway, here is a product that helps you create imaginary product boxes.
  • Here's another very similar product. We evidently have a small industry here that I had never heard of before this morning.
  • And yet another: This time, it generates a 3-D rotating video of an imaginary box!
  • After a little further research, I'm guessing that the “online affiliate marketing” industry is driving the imaginary box subindustry. On the other hand, the online affiliate marketing industry is itself imaginary, and basically a scam that labors mightily to stay just half a hair on the legal side of the razor. It's what the 419 scams would be if Nigeria had something like the FTC.
  • From Pete Albrecht comes a link to a video showing how well a 21-foot (!!) X-wing model rocket flies. (Flies? So-so. Dies? Spectacularly!)
  • Don Lancaster has a detailed article (PDF format) about why rooftop PV solar power isn't as big a win as everybody says it is. Definitely worth reading, and pay especial attention to the description of exergy, a concept I had heard of but not understood until now. As with TTL and CMOS logic, Don finally made it click for me.
  • Is Flash memory “write endurance” (i.e., the number of times you can change the state of a Flesh emmory cell) a serious issue or not? I always thought it was, but Eric Brombaugh (one of my EE friends who knows a thing or two about such matters) sent me a link to an article that changed my mind. If you're interested in Solid State Drives (SSDs) the parent page is worth a look as well.

  • Sorry for the silence here; I rarely go a week without posting but a lot of things ganged up on me. Many have noticed that I'm gradually moving toward posting less often but doing longer posts. I've discovered that it doesn't take me a great deal more time to write more detailed posts than shorter ones, but not posting at all on some days allows me to concentrate more fully on other projects.
  • There is a major total lunar eclipse tomorrow night, 2/20-2/21, which will be almost perfectly positioned for viewing in the US. See the NASA page for details. And if you're not up on lunar eclipses generally, ask Mr. Eclipse.
  • Flash memory is getting bigger; a 16GB SDHC card would hold a lot of ebooks.
  • Pertinent to the above: I'm not bullish on solid-state drives based on Flash, especially if they're positioned to replace ordinary spinning-disk hard drives. Flash storage cells can change state only so many times until they cease holding a state reliably, and extra hardware is needed to “spread the wealth around” so that frequent write activity in a particular location doesn't kill cells. Flash is thus best used for things like storage of music and ebook files, where you write data rarely but read it a lot.
  • Also, Flash may evenually be superceded by nonvolatile phase-change memory. We're still a few years off, but phase-change is faster than Flash and may even replace volatile RAM. No information yet that I've found on whether the cells degrade or die after a certain number of write cycles.
  • One other ebook note: Although most early reviewers claimed that the Kindle's SD slot was limited to 2 GB cards, the truth is that the card slot is SDHC and many owners have reported success with larger cards up to 8 GB. I don't have 8 GB of ebooks yet and may not for several more years. I just don't read that fast. For people who are actively converting their print library to ebooks, however, larger cards are a very important issue.
  • This nice link to NPR came over from Don Doerres, concerning the growing hobby of watching satellites. We used to go out and freeze butt looking for Echo in the early 1960s, but these guys are calculating orbits, photographing flares (momentary bright sunlight glints off polished satellite parts) and profoundly irritating the spooks. Watch the videos. Really watch the videos.

  • Robert Jastrow, the well-known NASA space popularizer, has left us, at age 82. My copy of Red Giants and White Dwarfs is in pieces from overuse, but as with Jastrow himself, I can only say: Mission accomplished.
  • I stumbled upon an interesting piece of art today (while following an unrelated link sent by Pete Albrecht) by the late French Impressionist Albert Besnard. Rather too casually entitled “Decoration for a Ceiling,” to me it suggests something altogether more cosmic: The reunion of all things and all people with God at the end of time. As Pete suggested for a caption: “Honey, I picked up your wings from the cleaners.” (And how about using it as a book cover? Right there in the middle is space for a title!)
  • D-Stix are amazingly rare on eBay (considering all the rest of the bizarre and obscure crap that I see there regularly) but today I finally scored the 464-piece set from the mid-1960s, and for only $10 at that. I've mentioned D-Stix here on Contra in the past, and on our second date, Carol and I flew a tetrahedral kite that I had made out of D-Stix. Building a replica of that kite has been on my do-it list for some years now. All I have to do now is find some purple madras tissue paper…
  • Jim Strickland sent me a link to a nice page from a German chap (it's in English) who has done considerable work with spark speakers. This isn't quite a flame speaker as I saw one in 1969 (which used an ionized propane torch flame) but is more like a modulated Tesla coil.
  • Also from Jim (in honor of the Westminster Dog Show, which ran last night) is an entry from what might as well be LOLDogs. Alas, the bichon didn't win his group last night. (There are too many poodles in the world, and not enough melted butter…)
  • Still again from Jim is a fascinating short history of the Teletype.
  • While we're talking ancient communication technologies, I finally remembered to link to a summary of Western Union's “92 code,” which is a list of 19th century telegrapher's numeric abbreviations that includes the ''–73–” that has been my email signature since my MCI Mail days in the early 80s. This is as good a summary as I've found, but it's missing a few codes that I've heard, like –86– which is short for “We are out of…”
  • And further in that same direction, here's as good a list as I've seen of the 10-codes used by CBers, police, and, of course, Broderick Crawford.

  • From Rich Rostrom comes a pointer to an amazing gallery of 50s-70s transistor radios and transistor radio ephemera. Almost every radio I had in that period or remember is here (including a nice one belonging to my grandmother) plus some true oddities, like phony transistor radio cases concealing liquor bottles, and a transparent pen with a single transistor floating loose in a little compartment full of oil, like a spider in formaldehyde. The photography is gorgeous, but the images are large and may take some time to come down. Nonetheless, don't miss it.
  • Jim Strickland pointed out that CFLs are now available in high wattages in the Mogul base, but alas, the bulb shown will not fit in Aunt Kathleen's floor lamp, as it's too long and would hit the shade frame.
  • From Pete Albrecht I got a link to a model rocket for people who aren't rocket scientists.
  • I haven't been to Snopes in a while, but a recent post aggregated on Slashdot suggested that it has been pushing the infamous Zango adware package for several months. The firestorm seems to have changed their minds, according to a report issued only today. There is a difference between serving ads and pushing adware, and if you're going to be considered one of the world's Good Guys, you have to stay on the right side of that line.
  • The video snippets taken by my late Kodak digital camera are all in QuickTime .mov format, which is a pain in the ass to edit unless you're a Mac guy. Pete and I recently found AVIDemux, a free open-source utility on SourceForge that converts .mov clips to .avi files, and in the limited testing I've been able to do, it seems to defy the codec chaos that reigns today and works beautifully.
  • Lego was fifty years old yesterday, and I will have to admit here that I never owned Lego as a kid. Never. I had a significant Meccano set from the time I was eight, which was my favorite toy until I got into electronics in a big way several years later. (I built a differential when I was nine, and hence I know how these slightly mysterious mechanisms actually work.) I boggle at stats like the fact that there are 62 lego parts for every person on Earth, which must mean that a certain number of people have a lot of them. People have built Lego logic gates, Lego cathedrals, and (more recently) a Lego Stargate. Wow. I have a few more years to build my missing Lego skillset before Katie (and her as-yet unborn sibling) will be ready to build her own Stargate with some uncle-ish help, but time flies. I'd better be at it.

  • Bob Halloran wrote to remind me that dual-booting Windows and Linux on a single hard drive is easy—but you have to install Windows first. When you install Linux it will see the Windows partition and configure grub so that grub will allow you to choose either OS when the hard drive's MBR gets control. If you install Linux and then Windows, Windows will overwrite the MBR with its own stuff, and grub will be gone. I'm going to try this with a couple of Linux installs alongside Windows (I want both Ubuntu and Kubuntu on that drive, at minimum) and will report back here in detail as to how it goes.
  • From Engadget comes a report of a prototype ebook reader (including handwriting recognition) shown without any explanation at the recent CES. This looks damned good to me, and is worth watching, at least in part because it's not tiny. I do not want a tiny ebook reader. I want something that shows an 8 1/2″ X 11″ page full-size. The dimensions on this gizmo are unclear, but it's sure as hell bigger than a cell phone. I'll trade a keyboard for a stylus, but I want the display to be at least letter-sized. (And I want a photovoltaic panel on the back to charge it when I'm not using it!)
  • There's nothing whatsoever preventing a piece of software from rendering a PDF ebook as reflowable text, and we're starting to get hints that Adobe may provide that ability, at least for the Sony Reader. This will allow people with big displays to read an ebook as pages, and people going crosseyed on small displays to read an ebook five words at a time. It should be the reader's choice, and I'm annoyed that that ability was not there from the beginning of PDF time.
  • Finally, I'm going in for serious gum surgery tomorrow morning, and I do not plan to be fully present intellectually for a couple of days. Do not look for a Contra entry before Thursday, but if you see one, it means I'm in better shape than I expected to be.

Iowa Caucuses Footnote

Now that the New Hampshire primary is history, we have another data point and might be able to get a little perspective on how bizarre Iowa's dominance of the primary phenomenon is. (See my entry for January 3, 2008.) This is due to the way the Iowa caucuses are conducted, at least on the Democratic side. (The Republicans caucus a whole different way.)

The Democratic caucuses in Iowa are a little like the platypus, in that people hearing how they work for the first time don't always believe it. Let me give you the short summary: At 7 PM on caucus night, Iowa's 1,784 precincts open their doors and the most motivated citizens stream in. There are no ballot boxes as we understand them. Instead, people literally go to the corner of the room under a sign with the name of the candidate they support. If you support Obama, you go stand in the Obama corner. If you support Hilary, you go to Hilary's corner. You can switch corners at any time, keeping in mind that after about 45 minutes, candidates without sufficient numbers of people under their signs are declared nonviable and tossed out, releasing their corner-standers to go stand somewhere else. (How this “viability factor” is calculated is complex and I'm not entirely sure I understand it myself, but it runs from 15% to 25%.)

Electioneering is allowed in the room, meaning that people can cajole others to move into their corner. Eventually, the party bosses declare that the caucus is over, and count heads in each of the viable corners. That isn't quite the end of it: What the numbers in each corner actually select are delegates to a state (not the national) Democratic nominating convention, but it's possible to know with some certainty on caucus night which candidates get how many delegates at the national convention.

There are multiple flaws in a system like this, including the fact that people who are not free at 7 PM on caucus night get no vote, nor do people like military personnel who are required by law to be elsewhere and cannot attend. (There is no absentee participation.) However, the worst of it is that everybody in your precinct gets to see whom you support—and that, in my view, is pure evil. I have tangled with party tribalists on occasion, and they are nasty, vituperative Right Men and Right Women who nourish grudges and hold them basically forever. If your neighborhood tribalists support one candidate and you support another, you'd better hope that they have nothing on you. (Zoning board members? Homeowners' association weasels? Such people are everywhere, and they have the power to make your life very difficult if they choose.) Even if there are no such tribalists in your precinct (and there are almost always a couple) people may feel pressured to vote with the rest of their families, or at least pressured against supporting an oddball dark horse candidate who appeals to them. Whatever cloud may hang over your personal decision as an Iowa Democrat, it is not a free election.

I'm amazed that this gets as little attention as it does. My readings and conversations indicate that the most committed Democrats supported Obama, and Big Media has all but handed him the nomination already. I can well imagine Obama's tribalists giving the “just you wait!” eyeball to people they know standing under Hilary's sign last Thursday night. (Yes, I'm sure there are Hilary tribalists as well, but Democratic tribalists tend to lean left.) It's impossible to know how different the results would have been had Iowa's Democrats allowed their people a true secret ballot. But would it have been different? Count on it.

  • Pete Albrecht sent me a link to a collection of free fonts with a German flavor.
  • Pertinent to the above, Pete sent a link to a nice free font viewer from AMPSoft.
  • Alas, font rendering is one of the areas where Ubuntu (and Linux generally) is way behind Windows.
  • An almost unbelievable piece of spyware is being installed by Sears, Roebuck on the machines of people who join “My SHC Community.” Good God: The software installs a proxy that causes all of your Web activity—whether associated with My SHC or not—to be intercepted. Disclosure of the spyware is buried in the small print way down in the thick of a 54-page “privacy policy.”
  • Here's yet another reason not to use Vista: It's all about protecting Microsoft and the Big Media outfits that Microsoft is trying to impress. What they did to this guy is criminal, but predictable. DRM technologies like this are the reason I do not buy downloads of music or video.
  • I inadvertently validated a lot of people's objections to ebooks recently: I lost the wall-wart charger for my Sony Reader. I simply don't know where it is, and the Reader is dead as a doornail for lack of juice. I'm sure it's here in the house somewhere, but until I find it, well, paper is looking mighty good.
  • Pertinent to the above: I recently purchased a 109-year-old copy of a theology journal containing an article on the Old Catholic movement. The journal is as readable as it was in 1898—and the several ebooks stored on my Sony Reader might as well be on Mars. We have to work on this. DRM and deprecated media formats aren't our only problems. Could an ebook reader be made with solar panels on the back side so you could charge it by flipping it over and laying it on a sunny windowsill for an hour?
  • Also in the ebook field is a report from Crave pointing to Igor Skochinsky's blog entries reverse-engineering the Kindle. There's some interesting stuff in there that hasn't been turned on yet, further cementing my conviction (now having actually seen Jim Strickland's unit) that as ugly as it is, the Kindle is the most innovative thing the ebook world has yet seen. That doesn't make it perfect, but I'm less dismissive than I was.
  • Every now and I then I spot something that makes me say, “Damn, that's clever.” The Make Blog highlighted earrings that can become earplugs when ambient noise gets too high. Carol and I don't go to many live concerts for precisely that reason: Everything's too loud and gives her headaches. Yes, the plug portion should be designed so that it looks less like a shuttlecock, but the inventor gets credit for thinking outside the box.
  • My Kodak EasyShare V530 digital camera (which died at warranty expiration plus three weeks) may be replaced by this model. 12 megapixels! Are we getting to the point of diminishing returns on camera resolution? (I actually like it for other features, like taking the picture when you press the button and not three seconds later.)
