It's UC-fucking-LA. It's not in the middle of a freeway, and I doubt she lives on a freeway either.


Looks pretty walkable to me. It may be a windy route, but in that case, bikes can ride anywhere cars can, except for highways, and even though it's near a mountain, I don't see anywhere that's 100% cut off from the outside world except for freeways. Zoom in anywhere and there are little roads there.

Hell, if I lived there and were faced with that option, I'd ride my bike on the freeway every day until I got a ticket for doing so.

There are differences in firmware though when you compare enterprise 7200rpm drives to desktop 7200rpm drives - error timeouts for example, and caching algorithms. You can tweak the drives to change the timeouts and recalibration times to make desktop drives behave better in arrays but they are _not_ otherwise identical. Also, although you can throw a SATA drive on a SAS controller (I have such a setup at home) throughput in an array is generally much better with SAS drives. At home I edit the timeouts on my personal drives, but I work in a data center and at work I would not take such a risk. If I screw up I risk down time for 300k people, and would put my job at risk. We buy enterprise drives across the board for servers.Throughput also isn't as critical on my home system. Running desktop drives on an array controller comes with certain risks, even if you know what you're doing. I have daily backups running at home to mitigate the risk.

Run desktop drives in an enterprise array, go ahead, and you'll see drives regularly drop out of the array even though nothing is wrong with the drives. They paused to recalibrate or error correction exceeded a timeout (so reliability in an array CAN and WILL suffer). You can yank the drive and reinsert it then it will run just fine for a while, then another one might drop out. Not acceptable for the enterprise, plus desktop hard drives are not rated/tested for 100% duty cycle while enterprise drives are. They are very similar but not identical. If you need a server (a tertiary DNS server or whatever) with a single drive, a desktop drive may be fine, but do NOT run a desktop drive in an array in the enterprise. Sooner or later you WILL regret it when 2-3 drives drop out of an array and you get called in at 2:00am to rebuild the server. Or, you could tweak the timeouts, risk fucking it up and put your job at risk.

And, on the higher end (such as you would install in an EMC or Netapp filer), have you seen any 10000 or 15000rpm desktop drives that compare to enterprise drives? I haven't.

For all the reasons outline here, unless MS is going to embed their own metadata into every image I use that promises the image is safe, and that if it isn't, MS will foot the bill. Even so, that won't help me if I print something and lose the original digital version with the metadata. Stupid, stupid, stupid.

The whole engine gets hot if you drive long enough. You can tuck things (on older V8s with roomier engines) on top of the intake under the air cleaner housing and it will get warm enough to cook some things. You're right, putting things on top of the decorative heat shield of a modern car won't do as much -- but still, you could wrap some hot dogs in foil and they'd cook enough after a while, even in a modern car.

The canonical tome on the matter was first written 25 years ago and has been revised twice since.

I've had the opposite experience. I just get basic APC UPSs and I've never had one cause me a moment's trouble. I can't say I WOULD have lost data if I HADN'T had them, but it HAS saved me the bother of having all my machines unexpectedly do a hard shutoff when the power dips for a second. You just have to test on occasion and replace batteries as needed because they WILL fail silently -- if the battery is dead, you won't know until the power goes out and your machine goes down.
