Steppenwolf planets: life in interstellar space?

Life needs light, right? Without a parent star, a planet stands little chance of developing the conditions under which comples chemistry can bootstrap itself into biological processes.

So goes the conventional wisdom, at any rate, but here’s a paper by two space boffins from the University of Chicago that posits the possibility of “Steppenwolf planets”, roaming the vast tracts of interstellar space with no star to call their own, but of sufficient mass and composition to harbour subsurface oceans heated by the still-active planetary core.

Technovelgy compares this to an old George RR Martin story with which I’m not familiar, but I seem to remember a more recent precedent in the latest Greg Egan collection, though the title of the story eludes me.And then there’s Peter Watts’ Blindsight… can anyone think of any others?

It occurs to me that, short of technological developments of a science fictional scale, the only real use we’ll ever be able to put these hypothetical Steppenwolf planets to would be… well, the settings for science fiction stories, basically. Oh, the irony!

But hey, lookit – I managed to write the whole post without a single “born to be wild” gag!

Ah, nuts.

Planned obsolescence: the lifespan of running shoes

Via Tim Maly, Matt Jones of BERG is planning on doing some running, and was quite taken by the new Mayfly shoes from a large sports brand that I won’t bother namechecking. What’s interesting about the Mayflys is that, as the name suggests, they’re ephemeral. [image ganked from BERG post]

Nike Mayfly

Of course, almost all consumer goods are ephemeral; what’s interesting here is the way that their limited lifespan is not only acknowledged but embraced by the product itself:

They are so light because they were designed with a definite lifespan.

They are only built to last for 100km.

On a good day, I usually run 10km.

These shoes are shoes I can use maybe ten times.

This defined sense of the object’s limited-life reinforces it’s narrative.

The thing is a clock.

Cradle-to-grave footwear product! As interesting as the concept is, I’m glad I’m not into running; for £40 or so, I’d want a pair of shoes I could wear more than ten times.

And good grief, but they’re ugly.. :-s

Preemptive leaks

After looking at kids adapting to living in public, here’s the other end of the scale: internationally-notorious public figures managing their public profile. Bush administration uber-weasel* Donald Rumsfeld has learned a few choice lessons from the sudden rise of radical transparency… or at least his publicity people have.

After Iraq and Afghanistan, Abu Ghraib and Guantanamo Bay, there are few rhetorical tactics Rumsfeld can employ to satisfy his hordes of critics. So he’s accompanying his memoir, Known and Unknown, with tons of primary source material: hundreds of raw documents detailing his thought process at the Pentagon, all searchable on his new website. This way, he’s not engaging with a debate he’s unlikely to win; he’s burying it under an avalanche of paper.

To put it uncharitably: when you’ve got a rep for being less-than-honest and unwilling to debate, you might as well let the documents speak for themselves.

This is interesting primarily because it subtly exploits a fundamental problem with all forms of communication, namely the signal-to-noise ratio. Or, to put it another way, the best way to hide needles is to put them in haystacks, and then salt the haystacks with a few distracting nuggets:

… RummyLeaks ain’t quite WikiLeaks: his documents have been officially declassified, and many paint him in quite the flattering light, on their face. But like WikiLeaks’ trove of war documents, Rumsfeld leaves it up to his readers to dig through a huge trove to find their own gems. A transparency measure, sure. But one that has the effect of snowing a reader under a ton of data, leaving them in the meantime with the narrative that he’s shaping.

I doubt this is going to make a huge difference to public perception of ol’ Rummy; them as have always backed him will continue to do so, and them as have always seen him as a weasel won’t take this hand-picked and carefully-manicured splurge of documentation as proof to the contrary. But it shows that old dogs really can learn new tricks… which is something to bear in mind every time you see your elected officials acting like they haven’t left the house since 1994. They’re not as naive or technologically out-of-touch as they’d like you to think.

Do you want to know a secret? Social steganography

Blah blah blah, the intertubes are eroding literacy, kids these days have poor communication skills, blah. Well, if we keep measuring those skills using old metrics, it’s bound to look that way… but kids (a definition that in this instance I’d consider expanding to “web natives”, a demographic that can extend into the younger end of Gen-X, if not further) are actually very sophisticated communicators, primarily because they’re adapting fast to the fact that a lot of their personal communication occurs in publicly-accessible spaces like Facebook. When your mum (or your boss) can be keeping an eye on your wall (or your Twitter stream), you sometimes have to code your updates so that they’re only comprehensible to their intended recipients. And what better an encryption key than your shared cultural references?

Posting lyrics to communicate your mood is one of the most common social steganographic tricks, because teens are fluent in pop culture in a way their parents aren’t. What teenagers are doing reminds me of Washington’s “dog whistle” politics, in which politicians deliver speeches that sound bland but are laden with meaning aimed at their base. For instance, Republican kingmaker Lee Atwater used to advise candidates to use phrases like “states’ rights” and “forced busing” to incite racial fears among white voters without actually using offensive language.

Obviously, one could regard the emergence of youth steganography as yet more depressing evidence of how dangerously overcomplex the web has made teens’ lives. But frankly, I’m kind of awed by the rhetorical sophistication of today’s teens. They are basically required to live in public (you try maintaining friendships without an online presence), but they crave some privacy, too. So they’ve taught themselves to hack language. They hack systems, as well: [Danah] Boyd has also found teenagers who “deactivate” their Facebook account when they log off so nobody can see their stuff or post comments. Then they “reactivate” it when they want to go back online and interact with friends. Presto: They create a virtual club where they control the operating hours. Color me impressed.

I’m tempted to see this as a reappropriation of a (virtual) social space by a generation that increasingly has little access to (physical) social space, though that’s doubtless either an oversimplification of the case or a fractional component of what’s actually happening.

But I think the important thing here is that young people will always find a way to do what young people have always done: distance themselves from the adult-mediated social sphere that they feel oppresses them (c’mon, every kid feels that way, even if it isn’t necessarily true), and create a new space to populate with their own argot, their own ideas and values. Of course, if you’ve always felt intimidated by kids and their weird ways, that’ll be cold comfort… but to me it’s a clear sign that we’re not losing anything essential about our human-ness to the web, we’re just finding new ways to enact it.
