Zoos are difficult things; They're constricting animal behaviour by construction, decreasing their welfare. The only way to argue that they are in any way a good thing, is via their educational value. But as +Jason Goldman's post, such education cannot be taken for granted!

I was at the San Diego Zoo today with +Enrique Gutierrez and +A.V. Flox. We spent about 30 minutes watching the Malayan tigers, cagey behavior and all, and I couldn't help but overhear the conversations between the parents and children as they filed by.

One dad told his kid, "look at those teeth, he wants to eat you." To which the child replied, "I want ice cream."

Another mom pointed out the location of the tigers (misinterpreting their pacing, which is a sign of cagey behavior, for waiting to be fed), and her daughters wanted to know when they could go to the gift shop to buy their souvenirs.

In all, I probably eavesdropped on a dozen such conversations.

It struck me as odd (and deeply troubling) that even the most minimal efforts by well-meaning (if misinformed) parents to engage their kids with nature - even if that nature is highly contrived - were generally unreceived. The kids would approach the glass, find the tigers, and not a single one spent more than a few seconds admiring these magnificent, endangered creatures. Most of those kids will never get to see a wild Malayan tiger, behaving naturally. And if we can't excite children about watching these rare animals, how will they grow up to see conservation as a priority?

I know that my followers are perhaps a self-selecting group. Most of you followed me because you're already interested in science, in nature, in animal cognition. Perhaps I'm preaching to the choir.

Even still. Please, parents, teachers: try harder. The ice cream can wait. The tigers won't.

Got this from Notch' g+. Really cool math/stats question!

Let's say we have a fair lottery where a hundred million people get one ticket each, and a winner is drawn at random each day. The winner stays in the pool even after winning. What are the odds that you win it once before someone else wins it three times (doesn't have to be in a row)?

In conversation: Alison Gopnik
On what’s wrong with the way we teach, and how a year out of university changed her son’s life

Q: What’s the traditional approach to learning at a university, and how does it square with what experts know about how people learn?

A: The traditional way of thinking about learning at a university is: there’s somebody who’s a teacher, who actually has some amount of knowledge, and their job is figuring out a way of communicating that knowledge. That’s literally a medieval model; it comes from the days when there weren’t a lot of printed books around, so someone read the book and explained it to everybody else. That’s our model for what university education, and for that matter high school education, ought to be like. It’s not a model that anybody’s ever found any independent evidence for.

See the rest of the fascinating interview: http://www2.macleans.ca/2011/11/01/what%E2%80%99s-wrong-with-the-way-we-teach-and-how-a-year-out-of-university-changed-her-son%E2%80%99s-life/

Wonderful little essay by Conway.
John Cook originally shared:
 
"These simple ideas can be astonishingly powerful, and they are also astonishingly difficult to find. Many times it has taken a century or more for someone to have the simple idea; in fact it has often taken two thousand years, because often the Greeks could have had that idea, and they didn't."

SCARY!

#geeky and #OMG
QUOTE: [Craig S Wright ] says: I was contracted to test the systems on a Boeing 747. They had added a new video system that ran over IP. They segregated this from the control systems using layer 2 - VLANs. We managed to break the VLANs and access other systems and with source routing could access the Engine management systems.

The response, "the engine management system is out of scope."

For those who do not know, 747's are big flying Unix hosts. At the time, the engine management system on this particular airline was Solaris based. The patching was well behind and they used telnet as SSH broke the menus and the budget did not extend to fixing this. The engineers could actually access the engine management system of a 747 in route. If issues are noted, they can re-tune the engine in air.

The issue here is that all that separated the engine control systems and the open network was NAT based filters. There were (and as far as I know this is true today), no extrusion controls. They filter incoming traffic, but all outgoing traffic is allowed. For those who engage in Pen Testing and know what a shoveled shell is... I need not say more.

One of the last pictures I took yesterday - Aurora Australis - the southern lights - dancing with the constellation Orion. An amazing moment.
