Some times you look at a page, it looks interesting and you wonder what's behind that page. Looking at the HTML headers often reveals interesting things about the site like what web server they are using, maybe what languges (php, python, ruby) and even more.

Safari doesn't have a built in way to look at those headers so here is a little applescript that does the trick. It depends on curl but Mac OS X ships with curl so this shouldn't be a problem.

tell application "Safari" to set theURL to URL of document 1
set cmd to "curl -I  " & theURL
do shell script cmd
display dialog result

There is this large flat space which almost seems surrounded by mountains. The Wasatch rise up sharply in the east. The mountains are still snow covered. From SLC I can't make out any towns or buildings but you can see some towers on the closest peaks. Flying in on a plane kind of robs you of the experience "How did I get in here and how am I going to get out"

Below is just a small movie which I took with my Casio camera and then converted to MPG4. I dont' know yet if Windows user will be able to see it.

On the Commons is a group dedicated to the concept of some form of shared wealth. What I thought was interesting was this list of thinkers and activist. Do you recognise them?

I was looking for the concept of intellectual technologies when this showed up. Can't read a lot of things on this site because they are in French but this one posting is enough for me. Lots of good ideas of how and why the net changes teaching and learning.

This particular explosion of technology has has profound consequences for how we organize production. It has consequences for the type of goods we value. We used to live in an economy in which the canonical source of value was an ingot of iron, a barrel of oil or a bushel of wheat. Such economies were based on knowledge just as much as our economy is, but the knowledge was of how to create a useful, physically-embodied good. We are moving to an economy in which the canonical source of value is a gene sequence, a line of computer code, or a logo. As Chairman Greenspan (1998) has often emphasized, in such a world, goods are increasingly valued not for their physical mass or other physical properties but for weightless ideas (see Coyle (1998)). In such an economy, what you know matters more than how much you can lift.
