Piaget was a weird guy. It should not be possible to sit around watching your kids, asking them occasional questions, and create a testable scientific theory that survives more or less intact for 75 years. He was good at noticing things--mostly, that kids don't think like adult human beings, and that they go through predictable progressions of alien thinking on their way there. The things that he noticed are really easy to see, if you know what you're looking for. Impossible not to see, in fact.
So we're waiting at the midwife's office. Also in the waiting room are a father and his 2-year-old (mom is getting her check-up). The kid alternates between fascinated shaking of a water bottle, and fascinated pushing of one wheeled-cube ottoman up against the second wheeled-cube ottoman. Clearly mass and vectors are the discoveries of the week. He can't figure out yet what these objects will do to each other without manipulating them physically--no surprise; outside-the-head thinking is pretty standard for the first two Piagetian stages. You'd expect to see it up through about age 7 for most kids. What I'm trying to figure out is whether he's in the Sensorimotor or Preoperational stage. He should be right at the boundary, on one side or the other. Finally I kneel down beside him and ask to borrow the water bottle. I hold up a board book and stick the bottle behind it. He's looking at me the whole time.
"Do you know where the bottle went? Can you look for the bottle?"
He starts looking immediately, obviously having fun. What's really entertaining is that he first looks in a basket on the other side of the room. Only after he catches sight of the bottle out of the corner of his eye does he come over to fish it from behind the book. Textbook early pre-op--knows that objects keep existing when they can't be seen, but doesn't yet have a clear idea of the properties of that existence. Can they teleport from one side of the room to the other? Do they change size randomly? Do they stay where you put them? He doesn't know yet. But he's working on it.
I'm going to make a very strange parent.
Non-work highlights; huge dragonflies, easily the size of a London mouse. The excellent lunch on Tuesday: Marriot World Resort does the best conference food bar none. John Mayer playing 'free falling' and 'message in a battle' (the accent!), which I parsed as 'I'll send an SMS to the world' and saying he prefers BlackBerry to Pampers...

Dog Pack Attacks Gator in Florida
At times nature can be cruel, but there is also a raw beauty, and even a certain justice manifested within that cruelty.
The alligator, one of the oldest and ultimate predators, normally considered the 'apex predator,' can still fall victim to implemented 'team work' strategy, made possible due to the tight knit social structure and 'survival of the pack mentality' bred into canines.
See the remarkable photograph below courtesy of Nature Magazine. Note that the Alpha dog has a muzzle hold on the gator preventing it from breathing, while another dog has a hold on the tail to keep it from thrashing. The third d og attacks the soft underbelly of the gator.

Things have been a bit busy for the last couple of months. IIRC, the last time I posted was just before Passover. We took the train from Chicago to Rochester, and David thoroughly enjoyed the trip. He got to sleep on the train, wake up on the train, eat breakfast on the train, go for a walk on the train, say goodbye to the train as it left the station in Rochester, say hello to the train when we got back on it ... I think you get the idea. He REALLY enjoyed the trip. We got a nice (if brief) visit in on both ends of the train trip with the Ropers.
Since then, we've been rather busy:

Wired's posted a photo gallery from the new show of vintage Japanese robots opening at the Sci Fi Museum in Seattle.
Iconic graphic designer Tom Geismar, whose firm Chermayeff & Geismar has created memorable logos for Mobil, PBS and other U.S. institutions, has been collecting the shiny bots for decades.LinkThe Science Fiction Museum and Hall of Fame in Seattle will exhibit toys from Geismar's collection in Robots: A Designer's Collection of Miniature Mechanical Marvels through Oct. 26. The vintage robots on display reflect Geismar's trained eye. "I've really restricted myself to ones that appealed to me as interesting, imaginative designs," he says.

This 1958 Japanese tin toy features Laika, Sputnik 2's brave cosmo-dog. Poor Laika. Link (Thanks, Erin!)

Vista users are complaining that Media Center refuses to let them record broadcast digital TV shows on NBC.Here's a screenshot of what they're seeing.
After we won the fight to stop the Broadcast Flag three years ago, over-the-air digital TV shouldn't have any copy controls -- and if it did, Microsoft shouldn't have to obey them.
Is it a bug in Vista's DRM systems? Did Microsoft and NBC cut a deal? What other receivers out there are going to obey the broadcasters instead of their owners?
Ah well. This beats whining about all those "out of heap space" errors I was getting, and not being productive.
Does any of this make sense to anyone out there?

CHORUS:
O the Shadows and the Vorlons should be friends!
O the Shadows and the Vorlons should be friends!
One side just wants evolution
The other side wants revolution
But that's no reason why they can't be friends!
I'd like to say a word for the Vorlon--
He eschews both extremes and takes the middle.
He eschews EVERYTHING but navel gazing,
And bugs us with the most annoying riddles!
Now, I would like to speak up for the Shadows--
They keep the dull times off us pretty often.
They sure made life exciting for my Home World,
Who's population's mostly now in coffins!
We should be feeling sorry for the Vorlons.
Their encounter suits ain't got no bathroom zipper.
They ride light years on end, with some few tortured souls for friends!
I sure feel sorry--for poor Jack the Ripper!
O the Shadows and the Vorlons should be friends... (KICK! POW!)
O the Shadows and the Vorlons should be friends...(ZAP! RAWR!), etc....
Anyone wanna add some verses?

So he's back in the same room we had on Tuesday, at Swedish First Hill, and once again I'm pleased with the quality of care we're getting through these folks ... but I really want our Little Guy to be hydrated and able to eat and sassy and breathing well on his own without need for supplemental oxygen or nebulizer treatments.
All good energy, wishes, prayers, etc gratefully accepted.

A comrade in arms on the event-driven vs. threaded debate has switched sides and is now a threading advocate. He's been having doubts for awhile but was finally convinced by an article about threaded vs. event-driven approaches in Java. I'm not so sure, though it's clear that some of the long-standing reasons that threaded approaches were bad are starting to go away.
My main complaint about threads is that the concurrency model they represent is too hard for most people to use and requires way more discipline than the average programmer seems capable of.
My secondary complaint is basically that they introduce latency. Every synchronization operation represents a piece of data that has to be communicated between threads. I wrote a long pondering article about threads and latency awhile ago.
One thing I've noticed is that reads are usually much more frequent than updates. This makes things like memcached a good idea. I think of memcached as essentially being NUMA without hardware support.
I think it's clear though that some level of threading is a good idea nowadays.
One interesting thing that Java has done that I think is an overall useful concept is making some data structures immutable so that no locking operations are required to access them. Python does this too.
This is going to require some thinking.

I finally have my dough recipe all nice and tweaked, and want to branch out flavor-wise. I don't have much experience with sweet breakfast pastries due to diet restrictions (long story).
I'm thinking something orangey?
