The brain truly is a system with terrible service availability. On average, after running for just 16 hours, it must be offlined for 8 hours to run maintenance tasks such as "scrub", "garbage collect", "trim",

In 1987, doxxing yourself was the norm. ~80% of the Usenet messages from the 1980s (to early the 1990s) had names, institutions, office addresses, and phone numbers attached to them too. Most were universities, governments, or corporate R&a

Sorry, it was a typo. I meant 2/3 (including common cables and fiber optics), not 1/3.

What an embarrassing typo! I was thinking of 0.66, and somehow I thought 0.66 = 1/3 (must've been distracted by the "2" in 1/2). I should've written 0.66 or 2/3.

Knowing superconductivity makes magnets less mysterious. Once you accept that physics absolutely allows the creation of a static magnetic field from a circulating current that flows forever in a zero-resistance inductor coil, then the exist
