  • More secure legally. You generally can’t be compelled to disclose a password that incriminates you (unless it’s already apparent that you’re guilty of wrong-doing) but a thing (physical key, fingerprint, etc) isn’t protected in the same way and can be demanded by the court.

    Whether biometric are secure or not is another question, they can be stolen like any other data or a motivated attacker could just take you or your fingers.


  • Look at MIT and UC Berkeley’s CS curricula and start tackling things that you haven’t covered. They’re both available freely online and you might still be able to find video recordings of Cal’s lectures somewhere (they recorded every class for students who weren’t present or had difficulty understanding in real time until 2015 or so but were hit with an ADA accessibility lawsuit because they weren’t captioned or something.)






  • Interesting that the one has such large capacitors in it. I imagine that is as last-ditch effort to keep the board powered long enough to finish flushing all of its caches in the event of a power failure.

    That’s exactly the point of power loss protection (aka PLP.) As a side effect of not needing to wait for a flush after a write synchronous write workloads are dramatically faster on enterprise drives with PLP.

    Edit: To add a bit of detail - you don’t need to wait for a flush after a synchronous write with PLP because the drive firmware can lie and immediately return from a flush call because there’s enough backup power to complete that flush if the power were cut.












  • The majority of our generation here in CA is PV during daylight hours and nat. gas generation plants (plus the odd nuke plant here and there) to cover any shortages. We have some battery storage to convert that PV generation capacity into night time power but not nearly enough. We have very little geothermal or tidal generation here.

    Most of the abusive cost of electricity here is PG&E offloading their $20B+ wildfire liability from 2015-2019 onto customers.

    Every single home I’ve lived in since the late 90s has used nat gas for water and central heating. Electric is becoming popular over time but gas is still very common.
