"The superjunction (SJ) charge balancing concept has been successfully implemented in silicon (Si) MOSFET power devices. Greater focus is now being placed on improving the performance metrics of wide bandgap (WBG) power devices with this technique. In this article, we summarize initial results that show promise in the application of the SJ structure in a lateral gallium nitride (GaN) Schottky diode."

There are few in the same category, perhaps Widlar or Gilbert for pure analog circuit design, or Bill Atkinson in later Mac software? It's a very short list.

Indeed. I have often wondered why university courses tend to use their own made-up machines to teach this stuff, as opposed to using the Apple II (or some of its near-contemporaries).

Agree, that's why I think it is so interesting - but it's also a rule that works in both directions (hardware->software and software->hardware).

The copy-protection stuff was completely puzzling back when it mattered, but of course makes complete sense now.

I hadn't seen the applesaucefdc.com stuff, that's great.

Not for this data, but in the past, yes - there is persistent pressure to do that for any maker of password managers, be it independent, in-browser or in-OS. (Source: I was a cofounder of a company that made a password manager as part of our product).

“When building structures are designed and built to required codes and standards, they have margins against failure, meaning they should be able to support much more load than they are expected to bear,” said Mitrani-Reiser. “In the case of Champlain Towers South, however, these margins against failure were too narrow from the start.”
