Students at every level, from grade school to grad school, face
dramatic changes in the institutions they attend thanks to new digital
technologies. PCs, the Internet, whiteboards, presentation software,
and other high-tech devices, once considered educational aides for the
library, the media lab, and the home, are increasingly a central part
of the classroom curriculum itself, with results that have yet to be
fully understood.

MIT's great lecture series on the classic Cormen, Leiserson, Rivest Introduction to Algorithms content. All software developers should be required to review the lectures in this course.

it's, like physics... yo.
the water washed away everything
but the chance to begin again
so we came from cities & towns,
from long golden fields
& we stood side by side
until we made a bridge to dry land,
back to a place
we have promised to hold safe
for each other's children,
back to a place
called America
the situation:
- water rising well above the 500 year flood stages. flooding on all fronts.
- buy a massive amount of sand (actually something that looks more like kitty litter)
- buy a massive amount of bags (burlap, plastic, etc.)
- buy a massive amount of plastic ties to tie off the bag openings
- put up 20-30 stations of sandbag manufacturing, each station consists of:
- two saw horses
- a wood panel with 3 holes cut out
- three traffic cones turned upside down in the holes
- the bagger: the bagger sits in front of an inverted cone and places an empty bag beneath the cone opening
- the digger: shovels the sand mixture into the inverted opening of the cone
- the finisher: twists the bag and ties it off with a plastic tie
- the pitcher: throws the completed bag into a forklift so that it can be loaded into a truck for distribution
- large machinery, dump trucks, forklifts, etc.
- heavy gloves
- lots of gatoraide, food stuffs
To quote that modern day poet, Sean Paul, "An pan we fi waan you to shake dat ting" [reference]. word. shake indeed! the Mars Phoenix explorer has successfully managed to shake dat ting! Not quite ready to move to the wet chemistry (see Britannica.com ref) analysis though yet...

really pleased so far with my macbook air (MBA)! my main machine at work is my ubuntu (hardy heron) dell 3GHz and my main machine at home is my Mac Pro. aside from being a perfectly capable machine in its own right (e.g. doing xcode iPhone sdk development, java-eclipse development, making keynote presentations) the MBA has quickly become my portable, always with me gateway to either machine via xwindows or remote management. as a bike commuter i get a little smile every time i slide this slim guy into my messenger bag. the keyboard feel great. i got a blue tooth mouse for longer work sessions. i also got a laptop case for it that was made from a recycled billboard sign. with the sling player it has become my portable television as well. yes, i am officially an apple fanboy now :-)
