    This isn't 'How to Think Like A Computer Scientist', but rather 'Introducing Programming with Python'. It's a good introductory text for learning Python. However programming is a v…

    You're right, there's no reason to try to correct the 20% of the population that believes the Sun revolves around the Earth. It's a lost cause; you win.

    Your statement was: "A RAID0 over three disks has about 1/3 the MTBF of a single disk." This is incorrect, the MTTF and MTBF are not significantly changed. Assuming you meant failu…

    Yeah, a closed source application installed as root, with the express purpose of accessing your webcam and microphone. What could go wrong?

    tl;dr: For RAID0 arrays there is a non-linear increase in the probability of failure, but the MTTF/MTBF doesn't change much.

    Comment #1617974

    While the probability of failure is nearly a function of the number of drives, the MTBF/MTTF calculations do not work that way. For example, if there were a probability of 5% that …

    You'll probably find this interesting reading on the internal architecture of SSDs: http://www.denali.com/wordpress/index.php/dmr/2010/02/02/ssd-interfaces-and-performance-effects …

    I back up several times a day, automatically. I've run RAID arrays for years with no problems, but all drives eventually fail. An SSD is internally a RAID0 that can be up to 16 wid…

    It really depends on the platform and requirements. On a desktop, a three-drive RAID0 provides about the same performance, and gives you nearly 40x the storage for a given price-po…

    Fedora, for example, already does this with UUIDs and the smolt project. A UUID is generated on installation and used for the 'ping'. The user opts-in at first boot, and the softwa…

    That seems to be a misunderstanding of the nature of a UUID. Simply replacing the model with the UUID provides no tracking in this use case, as it's a single purpose reference.

    Model numbers? Isn't that why UUIDs were created? Unique identifier, and anonymous: https://secure.wikimedia.org/wikipedia/en/wiki/UUID

    So women are only permitted to search for men? No lesbians allowed? After the eHarmony lawsuit and $500,000 payout, you'd think dating sites wouldn't want to repeat that disaster.

    It's a joke. If you're not using v4l, then you're rolling your own. So you either have to fix it yourself, or hold it upside down. :)
