  • 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.




  • Multiply anything by a billion people and it’s going to be a big number - food waste, plastic grocery bags, paper napkins. It can be a way to encourage people to think about their own contribution to environmental problems, but it often ends up distracting people into making a big deal of, and demanding personal lifestyle changes over, something that’s actually a small contributor to the real problem.
