Odd Lots

After giving it much thought, I’ve decided I rather like gathering links and other short items into lists rather than publishing each as a separate entry. Don’t know why, and I may change my mind. But for the time being, I’m continuing the ancient Contra custom.

  • While in Chicago over Christmas, we watched a movie I wholeheartedly condemn: Knocked Up. The film was completely unlikeable, and consisted almost entirely of out-of-control people screaming obscenities at one another. Sheesh.
  • That was depressing, but the other thing we did that same evening was play Rock Band, a Wii app with a string-less guitar and drum-less drum kit. That was way more fun. I’d hoped it would be a sort of Miracle Rock Music Teacher, but that’s not its mission. However, I did reasonably well at the drums and quite well on voice, even though there were only three songs on the whole list that I had even heard of, and none that I especially liked. You have to choose an animated avatar (there’s that word again) and after much searching for a bald-headed middle-aged white boy, I had to settle for the wonderfully named Duke of Gravity. The Duke was my choice because he had big bushy sideburns, which (apart from the color) resembled what I used to have in the 70s. Next time, can I be the Duke of Electromagnetism? (I didn’t know codpieces could have teeth.)
  • Spaceweather posted one of the spookiest sky photos I’ve ever seen, and I take some delight in the fact that atmospheric experts can’t explain it. If things like this happen every so often (even if only every 30 or 40 years) no wonder our ancestors believed in gods and angels.
  • The BBC has a very nice article on the mysterious Soviet Buran shuttle, which made precisely one flight comprised of two orbits plus an effortless return to Earth, all without a single human being in the cockpit. Thanks to Frank Glover for the link.
  • Pete Albrecht reminded me that, sandwiched between the end of the steam era and the beginning of the diesel-electric era, we had a very thin sliver of railroad locomotive evolution called the steam turbine-electric era. Behold the most formidable example, the C&O M1, a 4-8-4-8-4 (!!) in which a coal-fired steam turbine spun a generator, producing electricity that turned electric motors over the wheels. Man, they don’t make trains like that anymore. But they could. (After all, we have more coal than they have oil.)
  • The teeny, gummy Cruzer Micro Skin (so named because the whole thing is encased in a soft and slightly sensual plastic sleeve) is available in an 8GB version, and Amazon is now selling them for $12.99. (Marked down from $90!) I grabbed one; every MP3 I’ve ever ripped from my CDs will fit on that, with room to spare. The “big” 16 GB Cruzer Micro is already out there for $32.99–that’s a thousand times the capacity of my first thumb drive, which I bought back in 2001 for $50.
  • Here’s The Secret Origin of Clippy, a 15-slide retrospective based on Microsoft’s patent filings for animated screen assistants, of which Clippy was the least obnoxious. Tapping on the inside of the glass was clever and funny for the first twenty minutes, but now (with a plastic flat screen in front of me) it’s just, well, tired.

Odd Lots

  • Foxit Software (which sells a line of very good PDF-related software, including the Foxit Reader, which I use daily) has announced an e-ink based ebook reader, the eSlick. The device isn’t being shipped yet, but there have been some early reactions in Wired and other places. I’m interested because Foxit is unlikely to claim (as most ebook enthusiasts do) that PDF is the spawn of the devil. Worth watching.
  • The Loopy Idea of the Month comes from two Ohio academics who have recently patented the notion of collapsing hurricanes by flying around them in supersonic aircraft and (somehow) using the sonic boom shockwaves to scramble the storm. Apart from the fact that supersonic aircraft use fuel at a prodigous rate, I still don’t quite follow the physics of how this is supposed to collapse the storm. (Thanks to Pete Albrecht for the link.)
  • Jim Strickland passed a long a detailed how-to for extracting metallic titanium from white pigment. The process is straightforward, if (as it must be) highly energetic. I think the stickier question is working the titanium after it’s been isolated. Titanium is difficult to melt and very difficult to machine. I have a piece in my curio cabinet, and I’m very glad I don’t have to make anything from it.
  • Many people sent me the latest version of the old joke that “If Programming Languages Were Religions…” most of them lamenting that my favorite language—and my favorite religion—were not included. So it goes. I’m guessing that Pascal, like Catholicism, is patient: There will be only one programming language in use in the hereafter, and it will not be C++. You’ll have to go somewhere else for that.
  • The Wall Street Journal tells me that the RIAA is abandoning its mass-lawsuit strategy of copyright enforcement. It hasn’t worked at reducing music piracy, and its sole effect was making the music industry bigshots look positively evil. One can only wonder why it took so long to figure this out, and whether the damage can ever really be undone.
  • Here’s a wry peek at what we may see come out of the Big 3 bailout. Thanks to Pete Albrecht for the link. Have you driven a Pelosi lately?
  • Also from Pete comes word that Werner Von Braun wrote SF. This actually looks pretty good—gotta love that cover!

  • 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.
