One of my young engineers just got the first unit of a thing he
designed. He was all cautious about bringing it up a step at a time,
so I just pulled rank and switched it on in self-trigger mode. It
works.

It's an 8-channel high voltage pulse generator. We're not sure what
it's used for and the customer won't tell.

I've done timing to fire implosion fission bombs, and this doesn't
look to be one of those.

Yes, I said *fusion* bomb which is somewhat different. Timing is
critical for those. It's rather like grasping a wet bar of soap.

Some of the things that could be really fun aren't, because the good
bits are secret.

Yes, I can see how that would spoil things a bit from your POV.

One of my son-in-laws has a PhD in engineering mechanics and works for
a big lab that blows things up. He says it's not much fun because the
booms happen miles away and all he gets is data.

Er, yes. I think on balance I'd sooner be miles away in his position.
Jeff loves blowing stuff up. Haven't heard from him in a while; hope
he's okay and not been 'hoist by his own petard' if I might throw in a
bit of Hamlet here.
