I don’t have time for a post, but man, this is exciting.
Astronomers have discovered an Earth-like planet in the “Goldilocks Zone” of its solar system. Gliese 581g is the sixth planet of the Gliese 581 system discovered to date, and the most promising of them all (others have received media attention for their size/composition, or location, but until now none have been squarely in the middle of the habitable zone).
More info from Science magazine; the paper itself will be in the next Astrophysical Journal.
In my opinion, Steve Vogt is getting carried away, misquoted, or just trying to make a name for himself with that “100% chance” soundbite; I haven’t heard anybody claim that the *only* prerequisite for life is a water-friendly temperature, and (although I’m no xenobiologist) the fact that 581g is a ribbon world doesn’t inspire confidence.
Still, this is the best shot at finding extraterrestrial life we’ve ever had. In the words of a friend-of-a-friend: “This is the coolest f***ing time to be alive.”
[EDIT] The fact that Gliese 581g is tidally locked is probably a good sign, as Vogt explains in the Space.com article. This provides more of a range of temperatures, from the blazingly-hot side facing the star to the frozen dark side. In between, there must therefore exist a fairly wide zone of Earthlike “Goldilocks” temperatures. A planet that rotates with respect to its sun has a much narrower range of temperatures, lowering the odds (although there is variation from the poles to the equator, of course!)
By the way, Space.com needs to work on their fact-checking. Mercury isn’t tide-locked, as scientists have known for decades [NASA].
Dissociated Press is a program included with the popular source-code editor Emacs. When run on a text file, it generates hilarious free-associations (see the link for details.)
It’s a wonderful toy, but it’s particularly good on something as rambling as Robert Penn Warren’s prose.
I suppose that Anne, and juicy while Anne was inclined to bone and

"If you can guarantee results like that," I said, "you ought to have
So the poor bastard had gone to the Other stroked the big leather
couch. The discomfort was due, in part at least, to the fact that the
summer, and the world, would ever end. But that morning when Anne
said that she wasn't accustomed to hear anything in pants talk like
that. Not that she didn't try to persuade me, but I got back, late at
night, and went to bed. The condom on the park path, the twitch in

I'm going to fool somebody. I'm getting out of this race because you

He didn't say anything to that.
I’ve recently dreamed up a consistent model of time travel specifically designed to allow for good science fiction.
Up until now, I’ve typically used a branching-timeline model for the sake of simplicity, but it leaves much to desire in the way of plot: each time traveler finds themselves in their own, separate timeline, and there is eventually very little point in killing Hitler because he’s still alive in the original. To remedy that, I now introduce… [drumroll….]
The Ripple Model:
The central idea is an old cliche in lousy science fiction: you change the past, and the change propagates through the timeline until it hits the present. In most cases, it leads to absurdities like Back to the Future (“Oh my gawd, I’m fading! I have only hours of vaguely-defined metatime to make sure my parents meet, thereby leading to my conception, which is apparently not already guaranteed because only I have free will in this movie!”)
However, this approach can be made rigorous. Consider the following:
You leave 2010 and appear instantly (meaning that no subjective time passes) in 1930 in Germany. You shoot Hitler and immediately leave for France, 1940. Twenty seconds later, the world changes around you: the war-torn nation is replaced by a happy pastoral scene, but you are unaffected because your own history (starting from 2010 and including the time travel) is intact. You jump to the present, and find that WWII still happened. Seventy seconds later, the encyclopedia entry in front of you disappears, but you hardly notice, because a tiny fraction of a second after that, the ripple swallows your own remaining history and you disappear. Nearby, an alternative version of you that has never heard of Hitler or WWII carries on.
Note: This story borrows the character of Doc Labyrinth from Philip K Dick’s fantastic short stories. For the real thing, check out “The Short Happy Life of the Brown Oxford” or “The Preserving Machine”.
“What is it, Doc?”
Doc Labyrinth furrowed his brow and tapped his desk pensively. “That’s the trouble! I can’t remember.”
Sighing, I pulled out a chair and sat down. My friend was brilliant — no question about it — but more than slightly scatterbrained. I’m still not sure exactly what sort of doctorate he has.
“How do you know there’s a problem if you can’t remember what it is?”
“Well, I know what the problem is, in the general sense. I just don’t have any specifics.” He paused with the momentary hesitation that precedes all of his technical explanations. “You are aware that I have been studying Taoist philosophy?”
Until this summer, I didn’t really own CDs; mostly, I bought and listened to music online.
In the last couple months I got a few as gifts, bought some used ones online or in record stores, and somehow ended up with over a dozen, as follows:
Appeal to Reason
Siren Song of the Counter-Culture
Kind of Blue
In a Silent Way
Oscar Peterson and Count Basie:
Satch and Josh . . . . Again
Milestone Profiles [2 discs]
The Essential Bruce Springsteen [3 discs]
One Love: The Very Best of Bob Marley
New York Fever
Don’t Let The Bastards Grind You Down
And, in no particular order, here are other bands I like:
The Beatles, The English Beat, The Selecter, Westbound Train, The Dropkick Murphys, Flogging Molly, Bob Dylan, The Beach Boys, The Ramones, Catch 22, Gimp, Streetlight Manifesto, Bandits of the Acoustic Revolution, Billy Joel, REM, Cream, Eric Clapton, Led Zeppelin, Rancid, Desmond Dekker, The Mad Caddies, The Offspring, Less Than Jake, Reel Big Fish, Toots and the Maytals, The Skatalites, The Pietasters, The Planet Smashers, The Aquabats, The Cat Empire, Ленинград, and Sonny Rhodes (mainly for the Firefly theme). Also, the Rogue Traders because that one episode of Doctor Who was amazing.
Scribbles and Lies is the Livejournal blog of Dan Curtis Johnson, a comic book writer and programmer.
Every day, he posts something, and it’s always weird and usually vaguely science-fictiony. I can’t really be more specific than that, but the first post on his site gives an explanation of a sort.
That’s all I have to say, except that this is one of my favorite sites; if you see any unusual ultrashort stories on my blog, you know who to blame. Enjoy!
Here’s some pretty wallpaper I made using the random walk I showed off earlier!

I saw some Perseids tonight.
They were pretty.
Strange Maps is one of those amazing blogs that does exactly what it says on the tin, and does it brilliantly.
Today, it features a map of the world as it would be if the Earth did not spin; without the corresponding centrifugal force (sorry, centripetal; hold the angry letters), a belt around the equator would be elevated above sea level with the rest of the planet submerged. Check it out.
Almost every post is a unique find; I highly recommend the site, even for my less cartophilic readers.
