On the comet, the mighty comet,
the lander sleeps tonight.

"You know, when the complexity of a problem is growing exponential, even if you could use all the energy in the universe you will not able to solve it. That is the point."

I believe that I read that before the end of classical physics, things were getting very complicated. It took various theories--electo-magnetism, relativity, quantum mechanics, etc--to make sense of the experiments that were being done at the end of that era.

Similarly, we're now trying to resolve relativity vs. quantum mechanics. I believe that the complexity that we have now is due to the fact that we have to reconcile two theories that don't match "reality", and today's experiments have complex results, and when the answer to life, the universe and everything is found, and a new unified theory supersedes modern physics, a lot of the theoretical complexity will go away.

I expect it to be less than two centuries for that to happen.

Undersized Grouper Case Lands In Supreme Court

Interesting. Of course, the people who actually run the county will then "fire" the sheriff due to all the fedmoney drying up. Greed crosses all boundaries.

First Experimental Demonstration of a Trapped Rainbow Using Silicon

I thought of this too, but couldn't remember who wrote it. I remember reading one of the series he did on slow glass waybackwhen. It definitely caught my imagination then. Good stuff.

'Tis a good plan. Tends not to work for people with a shifted diurnal pattern.

Japan's Annual Nuclear Drill Highlights Problems

sysrammer Re:Disaster preparedness (43 comments)

If you're not zapped by the primary blast of radiation, the next thing to defend against is inhaling radioactive dust. While skin can provide some defense against radiation, the lungs have no defenses at all. "Hunker down until the dust settles" is a good defense. If I remember my old training correctly, it should be relatively safe to come out after 7 days.

"People want space flight because space flight is sciencey. They'll talk about colonizing Mars and saving ourselves from extinction, but that's really fancy talk. They want to live in Star Trek, end of story."

Hell yeah. Wouldn't need your "socialized medical research institute" in that case.

Sorry, I read "But really, the science will not be that different in two centuries from what we know today" and realized that you haven't been keeping up with either science or history.

Judge Says EA Battlefield 4 Execs Engaged In "Puffery," Not Fraud

sysrammer Re:Puffery (95 comments)

I don't think it's ok either, but the reality is that if you're young and immature or old and infirm, there are regs to keep fraud to a dull roar. All others, caveat emptor.

I think private orgs like Consumer reports, epinions.com, product reviews at shopping sites, etc, is an effective way to get past the bs.

One book could list everything that's mandatory, and the other everything that's forbidden.

sysrammer writes "Computerworld has an article on disk drive failures from the 5th USENIX Conference on File and Storage Technologies in San Jose, showing, among other things, "no evidence that Fibre Channel (FC) drives are any more reliable than less expensive but slower performing Serial ATA (SATA) drives", and that "that temperature seems to have little effect on drive reliability" (it looks like they're talking about temps closer to the upper operational limit, not catastrophic a/c failures, etc.). FTA: "About 100,000 disks are covered by this data, some for an entire lifetime of five years. The data include drives with SCSI and FC, as well as SATA interfaces. The mean time to failure (MTTF) of those drives, as specified in their datasheets, ranges from 1,000,000 to 1,500,000 hours, suggesting a nominal annual failure rate of at most 0.88%. We find that in the field, annual disk replacement rates typically exceed 1%, with 2-4% common and up to 13% observed on some systems. This suggests that field replacement is a fairly different process than one might predict based on datasheet MTTF." The authors did not identify particular vendors vs. the drive stats...their goal "is not choosing the best and the worst vendors but to help them to improve drive design and testing". Another note is that the study shows disk replacement rates, not necessarily actual failure. The article is at... http://www.computerworld.com/action/article.do?com mand=viewArticleBasic&articleId=9012066&source=NLT _AM&nlid=1 ...and the Usenix site is here... http://www.usenix.org/events/fast07/tech/schroeder .html mp"
