  • RAID is more likely to fail than a single disk. You have the chance of single-disk failure, multiplied by the number of disks, plus the chance of controller failure.

    RAID 1 and RAID 5 protect against that by sharing data across multiple disks, so you can re-create a failed drive, but failure of the controller may be unrecoverable, depending on availability of new, exact-same controller. With failure of 1 disk in RAID 1, you should be able to use the array ‘degraded,’ as long as your controller still works. Depending on how the controller works, that disk may or may not be recognizable to another system without the controller.

    RAID 1 disks are not just 2 copies of normal disks. Example: I use software RAID 1, and if I take one of the drives to another system, that system recognizes it as a RAID disk and creates a single-disk, degraded RAID array with it. I can mount the array, but if I try to mount the single disk directly, I get filesystem errors.



  • I really enjoy lying in a warm, comfortable bed, especially a little groggy from sleep. I’m happy to wake up an hour or so ahead of my alarm so I can have that experience. That said, if my mind is really racing with anticipation of the day’s concerns, it kind of wrecks the lie-in. I’ll get up an hour or two early, have an extra special breakfast, start chores or some other thing I didn’t think I had time for.




  • I used to pay a particular company by purchase order for this exact reason. CC takes 2-3% of the payment, but purchase order - they’ve got to get themselves into the company system, track the PO, invoice, track the payment…at the time, a common estimate was $50 to process a PO, and if you’re only buying $100 batches, that’s a big hit. Did not like that company, but they were the only place to get whatever it was I had to buy.













  • University is ok if you’re starting at zero and don’t even know what’s out there. It’s for exposing students to a a breadth of topics and some rationale of why things are as they are, but not necessarily for plugging them into a production environment.

    Nothing beats having your own real world project, either for motivation or exposure to cutting edge methods. Universities have tried to replicate that with things like ‘problem based learning,’ and they probably hope that students will be inspired by one or two of the classes to start their own out-of-class project, but school and work are fundamentally different ways of learning with fundamentally different goals.


  • It kind of sounds like OP morphed from hobbyist to investor, then lost interest when his investment lost value.

    There’s a lot of hobbies that offer a path to professional, and I’ve watched friends go down that path. It’s rarely a good experience - there’s all kind of things you have to do as a professional to make a living that you can blow off as a hobbyist/volunteer. There’s a lot more stress when success or failure is tied to whether you eat or not. You lose a lot of freedom to tell dickheads to fuck off.

    Never been into collectibles, myself, but the investment pressure seems insidious. Like, it’s one thing to trade cards among friends because you got doubles of something your buddy’s missing, but buying a rare card because it’s “underpriced” to hold until its price recovers is very different. The money is pressure to change from looking at your collection as good, fun, or complete and to looking at its presumptive cash value. Then you’ve stopped being a collector and started being a businessman.
