Submission + - Learn Lisp with games, comics, and a music video. (landoflisp.com) 1

smug_lisp_weenie writes: "Hi, I'm a longtime slashdot user and just finished my book "Land of Lisp", a graphical odyssey into Lisp programming. The recent interest in multicore chips is bringing functional programming and Lisp languages, such as Clojure and Common Lisp, back into vogue. But who wants to read all the dry, academic texts on these subjects? I hope my book and website (http://landoflisp.com) makes it easier for people to learn this stuff."

Comment IT and Medicine are a Bad Fit (Score 5, Informative) 294

One thing everyone seems to be missing here (including the author of the article) is that medical data is an odd duck that just doesn't fit easily into a digital record. (I'm an MD, a medical informatics guy and CTO at a medical software company)

If you're running a McDonalds you can easily computerize everything: You have a fixed menu your customers can choose from, and every purchase can easily be stuffed into a relational table. Medicine isn't like that.

Trying to enter a patient encounter into a contemporary medical record system is an extremely unsatisfying experience: Humans are just weird and idiosyncratic and every time you treat someone there will be parts of the patient visit you can't represent symbolically in a piece of software. This is still largely an unsolved problem- If you read the literature on Description Logics you'll see that even PhD logicians have a hard time symbolically storing this kind of abstract data into a piece of software, let alone a doc with little computer training.

Because of this, most current record systems use a lot of "free text" for storing medical info, which is a pretty ugly hack and everyone realizes this.

I think this is a major reason for the problems people have with digital records: They don't work very well right now for fully capturing a patient encounter in a rigorous, symbolic fashion.

OLPC Downsizes Half of Its Staff, Cuts Sugar 379

One Laptop Per Chewbacca writes "Nicholas Negroponte, the leader of the One Laptop Per Child (OLPC) project, has announced that the organization will be laying off half of its staff, cutting salaries of the remaining employees, and ending its involvement in Sugar development. The organization has had serious problems with production and deployment and has been fragmented by ideological debates as Negroponte shifts the agenda away from software freedom and towards Windows. Ars Technica concludes: 'The OLPC project's extreme dependence on economy of scale has proven to be a fatal error. The organization was not able to secure the large bulk orders that it had originally anticipated and fell short of meeting its target $100 per unit price. The worldwide economic slowdown has made it even more difficult for OLPC to find developing countries that have cash to spare on education technology.'"
