    The FBI's own stats show that about a quarter have outstanding warrants etc. Stolen cares being the most prevalent DUI's a bit under a quarter and suspended licences another quarter with not much left for the remainder.

    Not chasing and getting away are two complete different things. High speed chases are so dangerous to others and the police they need to be avoided in all but the more serious cases.

    You apparently neglected to read the FBI's research. While I know this does not agree with TV cop drama's oddly I do not think the FBI has any reason to play down the severity.

    Option 2 stop chasing them? The FBI's research pretty much shows that they are simply dangerous http://www.fbi.gov/stats-services/publications/law-enforcement-bulletin/march-2010/evidence-based-decisions-on-police-pursuits they show that most chases are for minor offences and that the suspects will quickly return to safe driving after the chase is stopped. Pretty much car chases are cops getting an adrenaline rush at the expense of the public.

    If it was open it could stay that way long term, as it stands it will be a niche market. Even MS is getting close to feature parity with 2012 R2's storage bits.

    ZFS is looking like a lot of what Oracle touches, something that will slowly wither and die as they try and suck every dollar they can out of it. It's to bad it could have been the killer file system. BTFS + bcache look poised to do 90% of what ZFS does, but it's also taken close to a decade for that to happen.

    Been there done that got the tshirt. Granted I do not use ZFS for storage heads in prod yet still trying out a disk level dedupe friendly backup format. ZFS has been a wonderful thing for VM and DB san/nas for awhile now abit the clumsiness of incompatible copyrights. Bcache is making strides by leaps and bounds as is btrfs to fill that void if Oracle refuses to open it up.

  11. Re:but what about cheap disk? on How the LHC Is Reviving Magnetic Tape · · Score: 1

    Ya the ggggp of this is about using cheap consumer disks instead of tape, I did not say it was a good idea :) You compared it to 4TB, 3TB drives are at least 7200rpm and the same cost per TB. Used as a sequential access device even a couple 5900rpm consumer drives push decent MB/s, there downfall is there short term bit error rate sucks and there long term longevity is atrocious. Those can be worked around but like I said if you want good enough and cheap LTO5 is that right now. In my case those disk storage heads are a buffer to take and short term retention so that 99% of my restores come from disk, The remaining bits are generally programmer issues that need a DB version from months/years back to get data from. Short-stroked drives buys me nothing my reads/writes are sequential of near enough to not matter. 15k vs 7200 the density makes up for the slower rotation. Honestly I really do not see much of a point of 15k drives anything that needs speed should be on SSD anyways, same goes for short stroking if you need lower latency's you should not be on a rotating media at least for hot data.

  12. Re:but what about cheap disk? on How the LHC Is Reviving Magnetic Tape · · Score: 1

    4TB consumer drives are about $160 or $40 a TB same price per TB as a 3TB.

    250MB/s is nice and all but I've seen our disk to disk over IB peg out at 3.5 GB/s per storage head so not really impressed.

    Looking around it looks nice and all but really poised to go against IBM's proprietary format, with a price to match I assume (can not easily Google a price). It's hard to be the most cost effective if it's 100k a tape head.

  13. Re:but what about cheap disk? on How the LHC Is Reviving Magnetic Tape · · Score: 1

    $32 a TB never count compression, 8.5TB with the newer tapes/heads and max "feature" not sure one price as it's a sole vendor product I wont go near it unless it's the only option.

  14. Re:but what about cheap disk? on How the LHC Is Reviving Magnetic Tape · · Score: 1

    Check the undetected and uncorrectable bit error rates for cheap disk. Tape drives even read everything written to insure it got there and is correct allowing it to retry the operation till it works or it fails out the tape. There is no "consumer" grade tape anymore without all those nice enterprise features baked in.

    Current pricing is about $60 for 1.5TB ($120 for a 3tb drive) for consumer disk vs LTO5 $30 + 2k for a tape head (LTO6 is more expensive as the takes a 3x the cost).

    So your saying keep POTS because idiots don't know how to charge a cell phone? All the POTS replacements (VOIP) I've seen come with at least 24 hours of battery for 911 but honestly who still needs them you running a fax machine or some other retro device? Cell phone chargers that work off AA batteries are a few bucks. Hand crank ones only a few more.bucks.

    Want to improve these system in a disaster, dismantle the POTS system but also stop allowing the gear on pole that should be in the CO and thus have a generator in place. 24 hours of battery for these systems is just not enough.

    No your wall outlets provide up to what the wire running to them will support past that and the breaker trips or the fuse pops (granted it's often much after but still generally safe for the wire). Newer homes have arc faults in a lot of places that protect from even more.

    Same thing for your car every branch circuit has a fuse of a given rating try getting more than 15 amps through your 12v accessory outlet.
