I have an electronics kit with TTL in it. (A 7400LS, no less.) All the
diagrams drive the LEDs directly from it.

That's TTL - it can source current, i.e. drive a LED
CMOS usually cannot source as much current.

It's all CMOS. In very few places it actually uses an extra transistor or
switch to drive an output.

See, you are doing it again; leave the job of finding reasons why you
are not qualified to the selection committee. Where someone lives now is
totally unimportant.
The reason why I might like you to be in the team is a simply sum: one
analyses what is needed and what we do have. We will have 2 PhD
positions available knowing what I and a fellow postdoc can, we subtract
that from the things we need and what is left is the minimum set of
skills the other team members combined need to have. Which is still a
very diverse set of skills and knowledge. My estimate is that with an
added Andrew, what is left may be possible to fill with one person. Or
if you start at the other end: for some likely kind of applicant to fill
one position we will have an almost Andy shaped hole left.

Well, I just checked, and I'm using a granny knot, too. I'm not going to
change it, it works after all.

It's probably more the exception rather than the rule. And usually only
at a few of the top places. Where I went, it was the case for CS and not
Elect Eng (or, AFAIK, any other engineering). John Hopkins is also that
way for CS. I know universities that have it that way for Electrical
(Caltech).
As for the number of people who go into MS saying they'll do a PhD and
"bailing out" - probably most of them in my department - which needs you
to take the MS. You typically don't get funding if you say you don't
plan on a PhD. So everyone says they do intend to do one.

I find I tie my shoes once or twice a day now, instead of every hour or so.

I really don't want to check if I'm doing it right. It's right because
it works!

Yeah, but you're the right kind of abnormal - same as everyone in this
group.
Normal people would never be interested in Haskell, mathematics or
POV-Ray. They wouldn't have a chance at enjoying graduate school - if
they somehow get in. You don't want to be normal.

I felt compelled to check. Apparently I have been doing it the right way
(i.e. a reef knot) all along. I have a pair of sneakers (very well worn by
now) that I tie once every five years or so.
