    I was just thinking the same thing. I was also thinking you can get a wide input voltage buck converter on amazon for cheap and use a bunch of cells in series as the UPS and the buck converter spits out 12V until it cant anymore. Then just wire up a charge controller to charge and balance your lead acid cells.







  • It depends on the generation. Older tapes and drives are a lot cheaper, especially second hand but hold less (tapes aren’t meant to be overwritten a lot though so typically you want unused. New old stock or new).

    Most homelabbers use LTO-6 or 5, and you can also upgrade your drive and still read your old tapes (except for the newest generations iirc)

    I haven’t looked at a price comparison for years, so I’m going off pre AI numbers. It was cheaper then spinning rust back then for $/TB (for my setup it was cheaper than rust by a massive margin since I have a quarter petabyte of storage. Amortizing a tape drive over that many tapes gets cheap quickly), but maybe its different now?




  • We don’t know the causality so its better to play it safe. What if pre-dementia or pre-alzheimers donors have the protien and it really is transmissible? For something as lethal as either of those diseases you would err on the side of caution and refuse donated blood with those proteins.

    A massive contributor to why HIV/AIDS is so bad in Africa is becausecof pooled blood products that were contaminated with HIV from donors even after we knew it was transmissible by blood… those companies packaged and sold or donated those products to Africa seeding the current crisis.
