You are not alone in that. The problem is that even the "RAID-ready" Barracudas did *not* obey the recovery time limits set by the RAID controller when they had read problems, that's why the controller timed them out. Given how long the RAID rebuild on the hot spare takes, it's only a matter of time until you have a double drive failure. We had lots of fun and data loss at a few sites from that.
Amen. If you don't learn that when you're young you're destined to get fat as your metabolism slows down with age. It's really hard to fix that when you're older. I started to work out at 30 and it was damn difficult at first.
Simple fix: Use apps full-screen. I noticed that whenever I have other windows visible, I tend to check them every now and then (especially the browser with Slashdot.) When I set the editor to full screen, I seem to be more productive.
No. Otherwise we wouldn't have evolution. Interestingly, for most organisms the mutation rate has adjusted itself such that it is fairly optimal for the environment. Viruses, e.g. HIV, have totally sloppy copy methods while more complex animals like mammals make far better copies - the longer lived the better.
Not everyone will be wiped out. The earth overall won't give a fuck and humanity won't die out either. The question is just how many [m|b]illions of humans will have to die before the natural control loops take effect.
Something tells me that if you do the math, cutting CO2 emissions will be way cheaper and safer than any of the options listed in the article. Seeding the oceans with iron, one of the more reasonable sounding ideas... OK, but how much iron would have to be mixed into the oceans to get rid of billions of tons of atmospheric carbon? At what cost?
I've worked on some pet projects during downtime (or after hours, or periods of boredom) and sold those to management after they were in a vaguely presentable state. E.g. tools that nobody else has the time or money to build/have built, something to improve workflow or management, etc. Right now I'm porting/converting a Wiki because there's been some grief about it. That's something that gets you visibility and recognition, and maybe a raise one day - at least better job security than the guy in the next cubicle.
If you like to work with people, customer/application/sales engineering might be for you. There's always lots of openings for people who know what they're doing because many in those areas are not very technical. Also these jobs often pay better than beginner/midlevel IT and programming jobs because they're closer to the revenue stream.
RMDIR [/S] [/Q] [drive:]path RD [/S] [/Q] [drive:]path/S Removes all directories and files in the specified directory in addition to the directory itself. Used to remove a directory
tree./Q Quiet mode, do not ask if ok to remove a directory tree with/S
That is one reason why mirroring isn't a backup, and why backups should ideally be off-line.
Even better, something like
dd if=/dev/zero of=/dev/hda
or similar. This wouldn't be the first time a RAID or disk controller, let alone a buggy file system or disk driver, did something like this. All it takes is a flaky DIMM contact. I've seen exactly this happen (except that it wasn't all zeroes but random garbage.) memtest86+ found a memory problem, and after removing and re-inserting a DIMM the system ran fine. Nothing was found wrong with the slot or DIMM contacts.
Just point out to them some realistic incidence numbers for the typical disasters in your area, together with the stats that 90%+ (can't remember the exact figure) of companies that lose their data go under. Plus the few-percent AFR of disk drives and maybe one for servers of course.
Especially since this was a blogging site... the data stream must have been astounding, probably on the order of megabytes per day!!! They could have backed up incrementals on floppies.
Anybody who uses disk based backup for a while finds out that it needs to be augmented by tape sooner or later. A disk based subsystem gets full pretty soon once you get used to the convenience. If you continue to buy disk drives it gets really expensive so people find that the best of both worlds is D2D2T. This reduces the size and speed of the tape subsystem you need, but doesn't make it obsolete. You need offsite storage anyway.
If the fiber is long enough or you use a fast WAN. I've been involved in a project where a customer rented space on the other side of a river and a fiber, then ran full speed FC to a tape library across the river. Clearly good enough to protect against fire and tornadoes, this customer's main concerns. Hurricanes or earthquakes, probably not so much.
The ones being breast-fed, I mean. These tiny children are being forced to look at naked breasts! Surely this is child sexual abuse! Those women should be arrested!
Nobody forces them - they could close their eyes while sucking. Some do, but some don't. We should put those on a registry, they're probably perverts! They should not be interested in boobs at that early age.
It would seem in today's morality, Men's breasts are totally acceptable, and can be published in photos and videos completely uncovered. Womens breasts however, are dirty and must be covered, even when feeding a child..

No. The math has been done and the geo-engineering solutions are thousands of times cheaper than reducing CO2 emissions.

Man you're picky. $250/hr sounds pretty good to me.

Ooh. Delay line backup. Now if we used something slower than light speed, say, a delay line?
What happened to deltree?
Replaced with RMDIR /S. Better yet, use /S /Q:

How the hell does a SAN work as off site storage?

Are you on GMT? Then it might have been the leap second. Otherwise, no. Although I wonder what took 25 seconds to fail.
Try once yourself to code conversion from "seconds since 1/1/1970 00:00:00" to any other user digestible presentation.
It's not as easy as it might seem.
Done:
$ perl -MHTTP::Date -e 'print time2str(1230796800)';

Maybe it's the concept of people flaunting the fact that they have (or can have) kids, when not all of us can?
So all those families with kids I saw on my afternoon walk today were "flaunting" something? And I thought they were just taking a New Year's stroll.
You have some serious issues I think.

US society has something severely backwards.
