  • Do normal people who don’t do this stuff for a living use Linux now, outside handheld gaming devices?

    I run into folks using linux fairly often in tech hobbies. Ham operators, DIY solar folk, people dorking around with a RasPi, etc. And some Normals who want a lighter experience than Win.

    Last dedicated windows box I ran at home was Windows NT 4, IIRC. Last time I had to use it at work was Win7 (?) before I retired. I do have a Win7 virtual somewhere around here I spin up every couple years to run something obscure I can’t get to run in WINE.





  • warning: some non-linux included below

    • minix
    • slackware
    • early Debian
    • FreeBSD (ftp installs instead of 20 floppies! OMG!)
    • Debian
    • Crunchbang <-- loved that original project
    • Solaris (friend gave me a Sparc 5)
    • DSL, Puppy linux (had a tiny netbook)
    • **Debian on workstations and servers since ~2014 **
    • various debian-based distros on RPI

    I do spin up other distros in a VM from time to time to see what’s what. Most recently NixOS since people won’t STFU about it. :-)


  • Title says plugged in and body says plugged in at 100%; these can be separate concepts if one has fine control over the charging voltage.

    Will leaving my things plugged in at 100% hurt it more than constantly unplugging at 80% and replugging at 20%?

    Plenty of academic research out there showing that pegging Li to 100% SoC reduces cycle counts to EOL (by electrolyte degradation and other processes), especially at higher voltages/temps. You didn’t mention capacity reduction associated with charging at freezing temps so I assume that is a non-issue in your use case.

    It seems to me that if leaving it plugged in is an option you have shore/mains/grid power. So I’d

    • charge to middling SoC and unplug the powerstation (according to the manual); and
    • run the loads off the wall socket

    Am I missing something here?

    offgrid with LiFePO4

    I live offgrid with Li on a very limited budget, so performance and maximal cycle life is a practical matter for me. Based on my own reading and experimentation I charge my 4S LiFePO4 to 13.8v (3.45Vpc) until Absorption falls to 0.10C then quasi-float at 13.31v (3.3275Vpc). I warm them to 50F and charge at ≤0.4C.
