  1. Re:Had went on? on Is Ubuntu Getting Slower? · · Score: 1

    That should have taken one page with one table that would take 30 seconds to digest.
    If they make me wade through 10 pages filled with data and bad grammar I expect some meat.

  2. Re:Sniffing out Parents? on Alarm Raised On Teenage Hackers · · Score: 1

    Parents need to make it clear to their kids what is acceptable behavior and what isn't. 11 year olds probably don't quite see the impact and consequences of what they're doing or they think that they're anonymous behind a wire and the Net is a free-for-all.

  3. What about exercise? on Brains Work Best At Age of 39 · · Score: 4, Interesting

    It is well known that regular intense exercise has a profound impact on aging and brain performance.
    I can't take a report serious that doesn't take the effect of exercise into consideration and doesn't even mention it.
    So does 39 apply to complete couch potatoes? Average Americans with little exercise? Athletes?

  4. Re:You've just described a poor interface design on WV Voters Say Machines Are Switching Votes · · Score: 1

    Amen.
    As much as I think that everybody should get with the times, you can't necessarily expect that from a 70+ year old.
    Disadvantaging old or unsavvy voters would discriminate against them which is unconstitutional. Case closed. Any ballot design must be usable by everybody, with very few exceptions like disabled people for whom who have to have an exception process.

  5. Parents? on Alarm Raised On Teenage Hackers · · Score: 2, Insightful

    This probably boils down to parents that are clueless. "But he was only playing on his computer!"
    So parents need to be educated that there's more you can do with a PC and an Internet connection than browse and play WoW.

  7. Re:Had went on? on Is Ubuntu Getting Slower? · · Score: 4, Insightful

    I just read it and found it pretty devoid of information. It is one of those mindless performance reviews in as many pages as possible.

    Where are any measurements that look at where performance was lost? Running just the distros does nothing to isolate what got slower. Trying different kernels and different X servers would at least show an attempt at understanding what's going on. Why didn't they compare at least one Ubuntu version with a similar Fedora version, let alone Kubuntu or xubuntu?

    As I expected: If a site employs people who can't write and has no editorial control that would weed out a glaring error like this you can't expect anything but quick and dirty superficial work. If an error like this that just jumps at you isn't caught, how many subtle errors in the data should I expect?

    One argument I heard, and you won't believe this:
    "Because then the recounts would take forever, and we might not have a valid result by January with all the court cases as a result."
    I don't remember which corner that came from, but it sounds as if it would take weeks to count a couple 1,000 votes in any contested districts.

  15. It stopped working already on Why RAID 5 Stops Working In 2009 · · Score: 1

    I've seen 3 cases of data loss this year in 6 drive RAID5 with 750GB or 1TB drives. One drive failed, and a second drive failed completely during the rebuild or there was a read error on another drive during rebuild. That is not a fluke given that rebuilding can take days if the system is under high load.
    Scrubbing costs too much performance if you want it to be useful. We're using RAID6 in newer products.

  17. Re:Network Vendors on Corporate Data Centers As Ethernet's Next Frontier · · Score: 1

    Amen. We looked at TOE cards for iSCSI and found that they were absolutely uncompetitive with adding CPU power and running the stack in software. There's a reason for all the commoditization going on. And collisions? Dropped packets? That's only a problem if you designed a bottleneck in. As long as you're aware that storage interconnects are different from your ordinary bursty LAN there is no problem.
    That said, I'm looking forward to an open source FCoE implementation.

  23. Re:scientology needs a worldwide campaign launched on Hacker Admits To Scientology DDoS Attack · · Score: 1

    I think it would be interesting to research how detectable electrical currents in the human body relate to physical, mental, even emotional processes.

    That's well known. EEG is used to measure brain function and detect abnormalities and lie detectors work but are unreliable and their output depends on many physical/mental variables, not just lying. Myography measures the electrical function of muscles.
    After a neck injury, I had an interesting procedure done: My hands were given small electric shocks and the resulting brain action was measured with an EEG like cap. IIRC the signal delay was measured. Fortunately the nerves were just slightly affected and recovered.
