Thanks, I havent seen that before. It took me 10 minutes to go through and it is very clear (took a moment to realize whitespace also alllows no character).
A couple of years ago I looked at tutorials and found it very confusing, but the spec is just great.
Is this really the full story? Why did then the whole world follow suit (in using TEL instead of e.g. ethanol)? Here it seems the reason was production cost of TEL was lower than ethanol: https://www.eesi.org/papers/view/fact-sheet-a-brief-history-...
Also, since there were less cars when this was decided and supposedly low dosage risk of lead was only known in the 60s, the original article seems to follow a bit of a narrow narrative. (For the workers the high risk was probably known though)
Actually the annoying thing here is, that the pointless discussion is achieved, while the link to the source code doesn't work (maybe temporarily overloaded from HN? Maybe dead)
On top of that I found the documentation and the book terrible. I thought it might be easier to understand what it does by reading the source code (didn't try yet)
So Georgia Tech is rated H+ which usually means all recognized (but a lot of text one should read, to check if online degrees are ok)
WGU is H+/- with a warning for online degrees which recognize life experience. One should expect to get the recognition application rejected.
