11 Trillion Gallons of Water Needed To End California Drought

sysrammer Re:But but but (322 comments)

"Some states are so stupid they just need to go away for good and California is one of them."

I agree. Once we disrupt the 8th largest economy in the world, all that excess production can be re-distributed to other places, improving more people's lives. The people there can then vote with their shoes and find other places to live. Roll out the welcome wagon--Californians, here they come!

Why Didn't Sidecar's Flex Pricing Work?

sysrammer Re:Economists... (190 comments)

No, because all stations would have been on the same playing field. When one player decides to behave with especial assholiness, then, yes, people will remember that.

Aliens Are Probably Everywhere, Just Not Anywhere Nearby

sysrammer Re:Paradoxes Be Damned (334 comments)

Perhaps we could also work on a spaceship that instead of propelling itself through the universe, remained stationary and moved the universe around it.

And we can call the universe warping mode "The Paradigm Shift".

Aliens Are Probably Everywhere, Just Not Anywhere Nearby

sysrammer OT Re:Paradoxes Be Damned (334 comments)

"That's a great ID10T story. Right up there with INSERT INTO MyHugeTable (ID, Value) Values (SELECT MAX(ID)+1 From MyHugeTable, "Value") which I found on a table with one million rows when client asked why his website was so slow. "

I see almost exactly this in a newly mis-behaving app that I have to deal with. The table in question has grown very large. It bothered me when I saw it the logic. I don't have great SQL chops, but this kind of logic only works well with a serial column, right, as the DBMS will track the highest assigned value? If not, then the thing has to do index or table scans to find the value in each invocation.

Is Enterprise IT More Difficult To Manage Now Than Ever?

sysrammer Re:IT has to accept new realities (241 comments)

If IT were easy and things never changed then anybody could do it. If you expect long term stability then you are in the wrong field.

Yep. Job security.

Virgin Galactic SpaceShipTwo Crashes

sysrammer Re:Not a good week... (445 comments)

"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.

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.

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.

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"
