  • Yes, I’ve been away from Contra for longer than I’d like, and the Odd Lots have been piling up. Some of that away was necessary for my sanity, and was spent by the pool at a resort in Phoenix, where Carol and I discussed things like the wonder of a single-celled organism that is 10 cm long. The secret appears to be evolving superior organelles. Bandersnatchi, anyone?
  • While I was gone, someone released a new OS for the Raspberry Pi: The Pidora Remix. It’s basically Fedora for the Pi. I haven’t tried it yet, but I’ll flip another SD card out of the drawer soonest and burn an image. Man, you have to run like hell just to stay in one place in this business.
  • The Raspberry Pi’s main competition, the BeagleBone, now has a 1 GHz ARM Cortex A8 version that ships with a Linux 3.8 kernel. BeagleBone Black supports the Linux Device Tree, which does a lot to decouple hardware details from the kernel. Looks terrific–now all it needs is an installed base.
  • I noticed a system resource draw-down when I had iTunes installed on my old and now electrocuted quadcore. The software took a lot of cycles and memory, even when it didn’t appear to be doing anything. The discussion has come up on Slashdot. (The poster also mentioned Rainmeter, which I tried once and found…ok.) I try to run a lean system here, and I frown on things that want services, tray icons, and 15% of my cycles all the damned time. (The Dell Dock does precisely that. For showing a row of icons. Sheesh.)
  • Amazon is setting up a new markeplace for short fiction, with a twist: It offers to share revenues on fan fiction with the authors of the original items. It’s unclear how many authors will accept that, but I would, like a shot. (I guess all I’d need are some fans.) In truth, Jim Strickland and I talked in detail some years back about opening up the Drumlins World to all authors who’d care to tell a story there, without even asking for money.
  • Clinical depression may be linked to sleep cycles, which appear to have a genetic basis. How to fix this is unclear, but I’ll testify that depression in the wake of losing Coriolis laid waste to my sleep habits for a couple of years. (Thanks to Jonathan O’Neal for the link.)
  • The Man Who Ploughed the Sea may soon be mining it…for uranium. I’d cut to the chase and just mine it for gold, so I can buy more ytterbium for my Hilbert Drive. Alas, there’s less gold in the oceans than we thought (1 part per trillion) and not much more ytterbium (1.5 parts per trillion) so maybe I should just extract the uranium (3 parts per billion) and make yellow pigments to sell on Etsy.
  • I’m not sure I buy this, but it’s an interesting speculation: That the Younger Dryas cold snap was triggered by a smallish asteroid that crashed…in Lake Michigan. Click through for the maps if nothing else. My favorite Great Lake is deeper and more complex than I thought.
  • Save the apostrophe’s! (From a fate worse than dearth…)
  • And save us, furthermore, from new Microsoft technology that counts people in the room watching your TV. Because having more than one person watching a TV show or movie rental is…is…stealing!
  • 3-D printing is still in the stone age (and the Old Stone Age at that) but if we don’t allow berserk patent law to strangle the kid in its crib, wonderful things will happen once 3-D printers are no longer CNC glue guns. (Thanks to Pete Albrecht for the link.)
  • I’m starting to think that 3-D printers like that will soon make one-off repro of small plastic parts like the ones at the center of kites practical. I guess the challenge is somehow getting the precise shape of the part into a file. If I weren’t trying so hard to be a novelist I would probably have a 3-D printer already. For the moment I’m glad I didn’t jump as soon as I otherwise might have.
  • Speaking of CNC…and guns: Plastic guns are dumb, dangerous, ineffective, and basically a stunt that seems designed (probably in Autocad) to make politicians say stupid things and make enemies. The real issue is cheap, portable CNC machines capable of cutting metal. That horse is out of the barn and beyond the horizon.

  • Egad. No, egad squared: A major literary agency has asked to see the full manuscript of Ten Gentle Opportunities. The novel is done, but I still have to format it for submission and write the synopsis and logline. I’m going to be busy for a few days, that is fersure.
  • IBM is taking a new slant on fluidic computers, one that operates via charged fluids. The hope is that this will allow better modeling of human brain operation. I’m skeptical, but hey, it’s a species of nanocomputer, and I’m certainly bullish on those. (Thanks to Mike Reith for the link.)
  • If anybody reading this has a 3D printer, I’d like to ask: Does the extruded plastic stick to clean copper-clad PCB stock? The obvious idea is to lay down a single-slice pattern in the form of PC pads and then etch the board with the plastic as resist. I don’t see much about this online.
  • From Chris Gerrib: How American radio stations got their call signs. One minor refinement: US callsigns beginning with AAA-ALZ and NAA to NZZ are not exclusively military. Amateur radio callsigns have used those prefixes for at least 35 years. (An OTA friend of mine outside Chicago got his Extra and selected AA9J as his call in, I think, 1976.)
  • People always seem to be recording meteors on dash cameras. I now have a dash camera. If I put it on my dash, will I see a meteor? Or will I get my money back? (Whoops. Found it in the bushes. All finds final. No refunds.)
  • Speaking of dash cameras: The manufacturer of the little sports camera I found in my bushes issued a DMCA takedown notice to a reviewer, on trademark grounds. (The DMCA has nothing to do with trademark abuse.) Hey, GoPro, Barbra is singing. Backtracking about the blunder will not help you. (Thanks to Tom Roderick for alerting me to this.)
  • Salads are way more dangerous than hamburgers. Alas, you can’t grill salad until it’s done to the center.
  • From Michael Covington comes a link to a story about how a Medieval copyist’s cat peed on his manuscript. The scribe drew a peeing cat on the damaged section, with an appropriate curse in Latin.
  • And we think we have a junk DNA problem: Amoeba proteus has 290 billion (yes, billion) base pairs in its genome, as compared to homo sap’s piddling 2.9 billion.
  • The reason all of us baby boomers didn’t die as grade schoolers may be that none of us lived in rich-guy gonzo-modern homes like these. (Why did I think that these houses were designed to ernhance estate tax revenues?)
