This is what compilers do already, one such strategy is to unwind the state to before the error and skip over the erroneous part. This can be a bit problematic in certain situations, such as a syntax error in a variable definition and the following flood of 'undefined variable' errors.
The repair strategy in the article is trying to optimise the quality of the attempted repair in order to provide better error messages to the user.
I think I'm missing a reference/joke =/
I spent a lot of time obsessing over it and the rest of my life was suffering as a result (it really exacerbated my trouble sleeping into a serious problem). In order to combat this I mostly tried to spend my time either being productive or doing whatever recreational activities my condition would allow.
Over time, as I started to eliminate worries (diagnosis, medication, learning what would cause flair-ups and just generally coming to a better understanding of it), it's become more or less routine/normal. Can't say the same will apply to other people, but that's how it has played out for me so far.
Best of luck and apologies that I can't give a more helpful answer.
A 4S battery (or equivalent) will have a nominal voltage of 14.8V and a maximum voltage of 16.8V, which leaves 2.2V extra, probably to account for losses.
Why 19V ended up being the typical voltage rather than rounding it up to something like 20V or 24V is beyond me (probably a matter of compliance, try checking IEC 60950-1 or related standards).
And I can certainly relate to the latter point: As an electronic engineer that likes to dabble with IC design, I'd love to consume some of the wisdom that the man could impart.
