Comment Surreal Numbers (Score 1) 278

There's Surreal Numbers by Donald Knuth. Given where you posted your question, you've probably read some of his other work, so you should know his style. Honestly, the love story in SN feels a bit bolted on, but he does give an eminently readable approach to Conway's version of number theory. There's a LOT of work left to the reader, but it sounds like you'd be good with that.


Disclaimer: I have an undergraduate degree in mathematics, but that was 18 years ago...

chicken nuggets, milk, a fruit and a vegetable

This much food is not supplementary, it's a whole lunch! Don't forget we're talking about a four-year old. How many four-year olds can eat all these and still be able to consume a sandwich?

I'm trying not to get into the politics of anything here, but my son (4 years old) eats noticeably more than I do. And I eat a lot; I run marathons for fun, and I'm not one of those slight people who's all leg. My son would consider both of those meals combined to be an appetizer.

I don't know about the kid in the article, but my son, he'd go back and ask if there were anymore of those nuggets floating around, oh, and can I have ketchup on them? You only brought a gallon? But I waaaaaaant it...

Comment Re:Just that pesky Constitution (Score 1) 949

There are many aspects of the Constitution that need updating. I mean, this bears repeating however obnoxious, but some of the Founding Fathers were slave owners.

Thirteenth amendment.

OK, so the electoral college is largely a product of the 3/5ths compromise on slavery. Should it have been removed when slavery was made unconstitutional? Should inter-racial marriage have been legalized then? How about restitution to former slaves? Was "separate but equal" constitutional?

Perhaps we want to clarify gun rights

What's to clarify?"

Well, let's see, we could take the model of Switzerland, where everyone and their dog has a gun, and ammo is sold at cost, but to buy ammo you either have to (buy & use it at a range) or (register the sale with the government). Could we legally require that in the US? Could we require a national registry of every gun owned in the country? Can we restrict children from owning guns? How about criminals? Felons? Violent felons? How about people who've threatened the president?

Are you really saying that this is sufficiently clear in the original text? Because half the time I can't even figure out what an individual FF would have said, much less what the lot of them would have agreed to, much less whether I agree with them.


Startup's Submerged Servers Could Cut Cooling Costs 147

1sockchuck writes "Are data center operators ready to abandon hot and cold aisles and submerge their servers? An Austin startup says its liquid cooling enclosure can cool high-density server installations for a fraction of the cost of air cooling in traditional data centers. Submersion cooling using mineral oil isn't new, dating back to the use of Fluorinert in the Cray 2. The new startup, Green Revolution Cooling, says its first installation will be at the Texas Advanced Computing Center (also home to the Ranger supercomputer). The company launched at SC09 along with a competing liquid cooling play, the Iceotope cooling bags."

US Air Force Buying Another 2,200 PS3s 144

bleedingpegasus sends word that the US Air Force will be grabbing up 2,200 new PlayStation 3 consoles for research into supercomputing. They already have a cluster made from 336 of the old-style (non-Slim) consoles, which they've used for a variety of purposes, including "processing multiple radar images into higher resolution composite images (known as synthetic aperture radar image formation), high-def video processing, and 'neuromorphic computing.'" According to the Justification Review Document (DOC), "Once the hardware configuration is implemented, software code will be developed in-house for cluster implementation utilizing a Linux-based operating software."
