- Suddenly the Sun woke up, perhaps afraid that it would get typecast for weak peaks. A sunspot number of 282 is only a little low for a sunspot maximum, and higher than I’ve seen since 2004 or so.
- The Atlantic takes on the interesting phenomenon of false memories, which I did back in 2009 in a series that started here and continued here, here, and here. As I write my memoirs, I’m checking anything I can against my sister’s memories, as well as any old papers or photos I have lying around in boxes. It’s amazing how much I remembered wrong, and I wonder how much may be wrong that I have no hope of every verifying.
- Did your favorite classic car ever appear in a movie or on TV? Well dayum, there’s a Web site for that. (Thanks to Ernie Marek for the link. And yes, there are loads and loads of 1968 Chevelles.)
- Reader DennisK pointed me to LXLE, a lightweight Ubuntu-based Linux distro designed specifically to look and work like Windows XP. I have lots of SX270s here destined to become bookends (and several that already have) so there’s no shortage of test platforms. I’ll let you know what I think after I try it.
- The Intel Galileo board will be shipping by the end of November, for $70. It supposedly competes with the Rapsberry Pi, but to me it looks like half the computer for twice the price. The Beagle boards have more promise. Anybody using one?
- Here’s a quick history of optical disks.
- What do you feed that pharaoh you just mummified? Mummified beef ribs.
- These peculiar ads (one depicting a brand of salami as a dirigible) don’t include Flying Bomb batteries (battery as bomb; what could possible go wrong?) or another brand of battery I saw in the 1960s that shows an Asian couple riding a battery like a horse. Or could it have been needles and thread? Oh, and meet Seaman Strangelove. There are many more Depression-era product posters (salami was popular) with similar metaphors on the walls of hipster restaurants everywhere.

This has been a busy two weeks, hence my silence. Carol had her foot surgery on Halloween, and she still can’t walk unassisted. She’s resting with her leg up on cushions, generously draped with bichons, catching up on her reading. Her mood is good. The leg is improving every day, though she still has two weeks to go before the cast comes off and she can put significant weight on both feet.
I’m working on a book project, for large values of “work.” The work isn’t all in the writing. The worst of it lies in the critical difference between a casual understanding of a topic and a detailed understanding. Ever since I got my first Android device and looked into writing apps for it, I’ve been reading up on Android and the ARM processors that lie beneath probably 98% of all Android instances. I picked up the broad strokes quickly: 32-bit single-issue load/store RISC architecture, 8-stage pipeline (for ARM11, at least), dual cache, lotsa registers, several privileged processor modes, SIMD instructions, and good coprocessor support. A little study revealed an instruction set optimized for staying out of system memory and keeping the pipeline full at all times. I had read about but not meditated on a remarkable ARM feature: Virtually all ARM instructions can be conditionally executed based on flags embedded right in the instruction itself. Do a comparison that sets the zero flag, and then any following instructions compiled/assembled to execute when Z=0 will percolate smoothly through the instruction pipeline but not do anything. In essence, instructions whose condition bits aren’t satisfied become NOPs. It’s like branching past a block of code without actually branching and thus messing up the pipeline. Pure brilliance.
You don’t really grasp how much of a topic you don’t understand until you need to explain it in detail. Most hardware guys know how exceptions work, in broad terms. But…does the CPU disable interrupts automatically upon entering an interrupt handler? Or does the handler have to do it explicitly? Things like that require drinking from the doc firehose in a way I haven’t had to for some time.
The book hasn’t been announced yet, but I think I can reveal that it’s mostly about hardware, and that I’m not the sole author. More later, but (I think) sooner rather than later.
I do that all day. In the evenings Carol and I cuddle on the couch and watch TV. TV is a little outside of type for me, granted. (Cuddling with Carol is a lot of what I live for.) But I was poleaxed at how good the comedy writing is on the nerd series The Big Bang Theory. I hadn’t seen more than a few isolated minutes on TVs at doctors’ waiting rooms, and once for maybe half an episode at my sister’s house. TBS has been running several rerun episodes back-to-back on most nights, and we’ve watched what’s been on for a week or so. That nowhere near exhausts the canon, which is now seven seasons and 145 episodes long. Sure, it’s over the top. But it’s a lot less over the top if you’re a guy like me than some jock who went into insurance sales. I’ve met a fair number of Leonard Hofstadters, and at least one remarkably close instantiation of Amy Farrah Fowler. Even if you don’t like TV much, give it a shot.
I’ve had to wonder if all the equations on the whiteboards are real and not gobbledegook meant to fool the rubes who are not into string theory. Maybe a physicist reader will clue us in.
More animal stories: We’ve had an 11-point buck wandering around the neighborhood recently, close enough to the house that I could stand about twenty feet from him and count his points. (He has a small extra one on his left side.) The deer have been thronging our property because the little stream in the gully has been running continuously now for probably six weeks. Ordinarily it runs for eight or ten hours after a bad rain and then goes dry again. Running for several relatively dry weeks suggests that a new spring has opened up on the mountainside above us. It’s not a lot of water, perhaps half a gallon per second. But it just keeps coming and coming, and I’ve begun to see mosquitoes on my office window, staring longongly at my exposed forearms through the glass. The low spot just before the Villegreen cul-de-sac is now a swamp. The deer love it. We see them in groups of eight or nine standing around the flowing water, drinking. Mr. Big Buck sits or lies there, his grey muzzle confident, daring me to disrupt the party by running out there and yelling dumb things like “Roogie! Roogie! Whoosh!” Probably not.
We’ve noticed something else: For the last six weeks or so, we’ve neither seen a fox, nor smelled a skunk. Ordinarily it’s one or the other down there in our gully. Now, nothing. Dare we hope that it’s because the 24″ corrugated iron pipe under Stanwell is half-full of water all the time? We’ve seen both species coming and going at the pipe entrance when it’s dry, though not at the same time. (They’re ecosystem competitors, and they fight. We had a dead skunk in the gully once for several months. Don’t mess with fox.) Nobody likes to sleep in a pipe that’s got eight or ten inches of water in it. We’re good with that.
If you’ve never seen the film Pirate Radio, rent or stream it. Carol got it for a dollar at the local Blockbuster while they were blowing out their inventory. Rehabbed fishing boats really did park off the coast of England once, broadcasting rock’n’roll and manic DJ chatter while deliberately tweaking the BBC bluenoses who eventually shut them down. A little raunchy but goodhearted, and the 1966 period look was uncanny. (I was 13 in 1966 and remember the era well, largely because I didn’t have a girlfriend to distract me.)
One of the other dollar DVDs she bought astonished me with its awfulness. Yes, I loathed Cowboys and Aliens. Sue me; it sucked bigtime. Every bad Western cliche that’s ever seen print or film was there in seething, wriggling, vomiting color–except when the film retreated into faux moody darkness so deep you had no idea what the hell was going on. The aliens looked and moved like gorillas in alien suits. The HQ spaceship was stolen–most appropriately–from Alien. The formidable Daniel Craig was utterly wasted. The aliens were so stupid they set down a wrist-mounted raygun right next to Craig so he could put it on and start blasting them. The plot made very little sense except when it was utterly predictable. I’m glad we got it for a dollar–which was probably five dollars more than what it was worth.
Dash threw up on our bed late this afternoon. We got it all before it soaked through to the mattress, but we have to wash and dry several more rounds of sheets and blankets before we sleep tonight. We have a perfectly good bedroom downstairs–but Carol only has one good leg for the time being, and there are a lot of stairs. Talk atcha later. I have to go upstairs and throw another round in the dryer.
- $10,000. Software written in Pascal. Windowing interface remarkably like the Xerox Star’s, on which I’d been trained the year before. I spent a wistful hour putting it through its paces at a nearby computer store in Rochester, NY. I’d just spent $4000 on a CP/M system three years earlier, and didn’t have another $10K lying around. Nice retrospective on poor Lisa, who never got the respect she deserved. Market niches matter, and it’s not always possible to create your own from the quantum vacuum.
- Solar Cycle 24 is definitely double-humped, and its second peak could well be peakier than the first. This doesn’t make it a strong cycle, by any means, but we thought the whole deal was over after the first peak in 2011. Not so.
- An amateur telescope maker in Utah bought a 70″ spy satellite mirror at a scratch-and-dent auction and built the world’s largest amateur telescope.
- I haven’t written aliens into my SF much, at least since I first thought deeply about the subject in college. This is part of the reason. I had planned out a story in which Earth contacts an alien race with so old and rich a culture that their language consists of context-sensitive metaphors within similes within puns within knock-knock jokes. I never wrote the story because I could never figure out how to crack the problem.
- Your graphics card is getting faster, but there’s no guarantee that you’ll even notice. I think this is what the term “diminishing returns” was coined to describe.
- From the Major WTF File: One of my readers sent me this link, and I’m still trying to figure out what these creeps are up to. I’ll post a separate entry on it when I have a little more time to research it. But look yourself up: I’d like to hear about it if you’re on there too.
- Little by little, people are starting to figure it out: Fat will make you lose weight and keep you healthy. Sugar will f*(&ing kill you.
- I was told by a cardiologist 20-odd years ago that gum disease was related to heart disease. It seemed like a stretch at the time, but since then I’ve seen a number of studies indicating that it’s true. Floss, don’t infarct!
- Slate has a short piece explaining what makes a continental breakfast continental. What made me laugh was an embedded Key & Peele bit in which Peele delights in discovering Fruit Loops at his hotel breakfast counter, as though they were rare treats. Bartholomew Stypek does the same thing in Ten Gentle Opportunities: “Carolyn had gifted him with sacks of delicacies that any nobleman in the realm of Ttryngg would kill for: Doritos, Cheetos, Pringles, Ruffles, and sweets baked by elves.”
- The Marines are about to begin hunting Somali pirates. If I were a Somali pirate, I would be thinking about early retirement.
- Cities, like ogres and onions, have layers. The deepest and oldest of those layers can be forgotten by all but a few. Here’s a marvelous quick tour of the some of New York’s less visible layers. No ogres. We hope. (Thanks to Esther Schindler for the link.)
