  • I do recall google apparently stopped using raid in some data centres, but it was because they had whole-machine redundancy.

    RAID is probably redundant for some of the uses it used to have, like optimising read performance by using many drives (SSD is fast) and honestly I suspect that SSDs are probably more reliable as they don’t have a bunch of platters and bearings and screaming rotational speeds.

    So if you needed it for a base level of reliability, an SSD on its own may have exceeded that.

    I suspect there are still uses for drive redundancy in some high availability setups… although your friend might be right. If the likelihood of drive failure is lower than other parts in the machine and you need high redundancy for availability it might make more sense to replicate the whole machine rather than the drives.

    It’s possible redundancy specifically for the drives was an artifact of unreliable drives back in the day 🤔 they might have a point! I think it’s likely still useful at times though.

    I’d rather hotswap a drive than set up a new server, even if it’s a less likely scenario.












  • When I was about 15 I woke up at about 4am, super distressed, and I knew someone had died. I didn’t want to go look so I just hoped it wasn’t my mother or father, shamefully I thought it would be better if it was a grandparent. There was a lot of going over possibilities and mental bargaining.

    Eventually I calmed down and realised it was irrational and finally got back to sleep, the following day I found out it was a close friend of my mother’s. She’d killed herself. I don’t understand what happened, I don’t really believe in the supernatural but it was very strange.


  • currently governments fund and slash funding to all sorts of things according to political convenience… I just want to see all those decisions validated entirely on merit by someone who understands it.

    if it’s popular with the mob but it’s not true or doesn’t work, well, we don’t do it. president isn’t an expert and can’t say shit, and especially can’t do stupid things so he can sound tough in a media release. we can’t afford to keep dicking around with whatever sounds good to win popular support with the lowest common denominator while the world goes to shit.

    the world is far beyond the level of complexity where any one person could understand enough to make off the cuff, meaningful decisions about big issues. people need to stop thinking they can vote sensibly on policy or policy performance on almost any issue, let alone all the issues.
