  • the best device for school is a generic laptop that you can easily find guides and replacement parts for. That way you can fix things

    This is the right idea. The qualifier is unnecessary. Repairability is always valuable. The more generic a device is, the more spare parts for it there will be on the market, and the longer those spare parts will be continue to be available on the market.

    Buy common refurb/resale tech. Keep it for years, or decades.



  • Secret Panel: The guy returns home. His elderly mother is playing a keytar and asks “did you promote my band at the club, son?” The guy nods his head. In the background is a poster of mom playing the keytar, above her reads the band’s name “Mental Illness”

    I mean, trying to promote your group during someone else’s gig is just rude, so DJ guy was totally right.













  • The most genuine, personal emotion is grief. I think for people who understand grief, watching a character depict it in a story is deeply compelling, possibly to an unhealthy degree.

    It is functionally impossible to share grief in any meaningful way, even with other people who are grieving for the same thing that you are.

    If you could share the deeply personal parts, they would cease to be personal and thus cease to be meaningful.

    This doesn’t mean that you should camp out on your grief, indulge in it long-term, wallow in it like a pig in mud.

    It does mean that you should spend some time thinking about the things that make that feeling of grief so sharp, so personal for you, and treasure them. Only humans can create meaning, can produce it in other things, can extract it out of the mundanity of existence. You did, and you should hold on to the reasons for that, even as you allow the pain of the grief to fade.


  • Well the “critical/irreplaceable” qualifier is kind of important - that’s why I specified it. It’s up to you to decide what that means for your data and risk tolerance.

    For everything that I consider irreplaceable, I’m not comfortable with anything less than 100% duplication on the live system, and also an external offline backup. Even with enterprise-grade hardware, I don’t trust storage devices, they’re all destined to fail. Storage is the most important part of a data server, and should be treated like it is constantly trying to light itself on fire, like a library with wooden shelves lit with torches. All the other components are just as unreliable, but more expendable.

    Admittedly, when you account for hot standby drives, the cost is that my storage availability is only 40%. A 16TB storage pool is in fact 5x 8TB drives: 2 mirrored pairs and 1 standby. On the plus side, thanks to ZFS and TrueNAS those drives can be whatever, no need to worry about RAID considerations for matched drives. SAS or SATA? who cares? They can even be different speeds, ZFS will compensate. Buy whatever is the right size for the pool, let the system deal with the other issues.

    Can you put a price on stability? longevity? peace of mind?

    The server hardware is all old repurposed stuff - a desktop build from 2013, secondhand data center surplus, refurbished/used drives, none of it’s worth much and almost all of it is well past end of life, any part of it could fail without warning at any moment. It doesn’t matter, it is highly reliable because the redundancies have redundancies, including the boot drives. Trying to squeeze every bit of value out of the hardware is a losing game because it’s basically worthless anyway, but the same would be true if it were all new top-of-the-line gear. The hardware is expendable, the data is not. Buy more cheap hardware, plan for it to explode, learn how to build stable, recoverable systems.


  • Used data center drives are great for a home lab. They’re built like tanks for hundreds of thousands of hours of constant operation. Unless you’re running a business hosting a bunch of public-facing websites out of your garage, you don’t have that kind of workload (and if you are doing that you should just be buying new drives anyway and writing them off as a business expense).

    Data center drives get replaced when they hit a ceiling of operating hours, with no actual faults, or if they experience any minor faults (it’s a business expense - drives are consumables - data centers have storage rooms of spares sitting around, they just replace them).

    Any competent reseller should be able to give you a SMART report, and that should tell you if there are any major issues (generally they don’t get resold if there are, nobody will buy them). If the seller won’t give you a SMART report then obviously don’t buy, they’re either a scammer or incompetent.

    If your array redundancy is set up properly then there’s no reason to be “scared” or trust in “good luck”. Assume luck will be bad. Mirror every storage device that has critical/irreplaceable data on it, and have at least one hot standby drive in every pool. Don’t bother with complicated striping schemes to try and scrape a little more storage space out of your drives, that’s dumb. One-to-one mirroring for every drive. Storage drives are consumables. They will fail, not if but when, even if you only buy new. Learn to read a SMART report. Enjoy quality hardware with no real problems at low prices.
