The Secret Government Rulebook For Labeling You a Terrorist

sysrammer Re:Terrorist is an impossible label (242 comments)

I know USAF makes practice bombing runs on American cities. It has done so at least since the 50's. I imagine they did it earlier, too. It's called "training".

World Health Organization Calls For Decriminalization of Drug Use

sysrammer Re:Finally! (474 comments)

Sounds like a good idea. I've been wondering how we're going to get out of the for-profit prison business. I'm sure this would lead to its own problems, but, hey, that's what humans do. Fix a problem, create a problem.

$500k "Energy-Harvesting" Kickstarter Scam Unfolding Right Now

Ah, a crystal set, then? I remember those. I was mildly amazed when I learned that you could have a "self-powered" radio.

Getting the Most Out of the Space Station (Before It's Too Late)

sysrammer Re:Get rid of NASA (155 comments)

USAF had decent flying shapes in the 50's. None could handle re-entry temps. Spam-in-a-can could. And it supported defense research (ICBMs).

On the other hand, we had the USAF Man in Space Soonest program. The acronym proved prophetic, as we missed getting into space first.

Getting the Most Out of the Space Station (Before It's Too Late)

sysrammer Re:The shuttle's failings were largely (155 comments)

I largely agree with you. A caveat, though, is the fact that shuttle *needed* USAF funding to get off the ground. Whether or not it was a good thing that it got off the ground is a topic for another thread.

The Strange Death of Comet Ison

Oh lord, you realize you just started another conspiracy theory, right? I should start an email chain tonight, attributing this to some vague authority. I wonder how long it would take to propagate.

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"
