  • 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.


  • Treasuries are nice because they’re convenient and low buy-in, but their yields are crap, sometimes a little above inflation, sometimes below. TIPS are a decent way to hedge the inflation risk, but (IMO) it’s still really for people who are more worried about losing their savings than living off it. (i.e.: if you have, say, $1e8, you can live pretty comfortably off $1e6, even $1e5 in a lean year, so your rate of return doesn’t really matter)

    For me, personally, the limited bond exposure I have is all corporate and mostly junk, bought through my broker in the secondary market, with maturity 10-20 years out. Until fairly recently, junk bonds were the only way to get yields above 4%, and that’s kind of my mental benchmark for gaining relative to inflation. One downside of corporate bonds is they generally have a $10k minimum.


  • That drop was when the Fed was raising interest rates to stall inflation. Interest rates up, bond values down. But the drop in VTINX was only 20% over all of 2022, where OP is showing 50% in maybe the first quarter.

    Incidentally, the sensitivity to interest rates is why I don’t like bond funds. If you buy actual bonds, you get the face value back at maturity, where bond fund are forced to mark them all to current market prices to calculate NAV. IMO, this negates the main “safe” factor in holding bonds.



  • No. If you’ve been saving for 30 years, then you’ll have 30 years of accumulated 10±20% annual gains, which should be something like 16x your start, but could be 100x if you’re lucky or 1x if you’re not. Regardless, an historic crash on retirement day may take that down to 12x your start, which is still pretty good, and will be fixed by the following couple years.






  • 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.

    The relevant text of the law is

    The products must be available to all menstruating students in restrooms regularly used by students in grades 4 to 12 according to a plan developed by the school district.

    so, I think “boys bathroom” only in the case where a school has trans-boy without puberty blockers or hormone therapy. Clearly a very edge case, but right-wing propaganda depends on blowing up rare events or special circumstances, pretending they’re happening everywhere, all the time, and therefore an immediate threat to the way their audience has always done things.
