Nope, wasn't aware of that. I just hook up the shop vac and go.
Done it many times and never had a problem. Must be lucky.
Wonder why the even faster moving air at the tip of the compressed air
nozzle doesn't generate static.
Anyway, I never noticed any static when vacuuming anything here, so
maybe it's against the law.
But thanks for the heads up.
If I have any problems in the future, it'll be your fault.

Yes, so far...

Because it also contains a lot of moisture, for one. It also doesn't
contain dust.

Not many people see the bullet before it hits them, either. :')

Just don't give me any static about it. I tried to warn you.

"They"? You some kind of RAMophobe?

Murphy's 32nd Law of Computer Operations:

Computers never work the way they are supposed to. Especially when
nothing is wrong with them.

Nope - Murphy's 21st Law of Computer Operations:

The only thing worse than an end-user without a clue is an end-user
who has a clue - usually the wrong one.

Buy an air compresor.

Will do. For my jackhammers. I'll still use vacuum
for the PC.
Don't want to blow dust on the doilies.

Same here. I could probably build a new one of almost everything I owned
with all the leftover parts.

I propose we amend this to create a 21st Law, Part A:

"The only thing worse that an end-user without a clue is an end-user who
has a screwdriver and the ambition to use it."

end-user = a wanna-be engineer.

Hmmm, maybe, but it depends on your perspective. After 20+ years in the
SW industry, it seems most end-users want to believe think they know
better than the engineers. Not to say all, but some.

I do have the utmost respect for those who can make all these computer
thingies actually do what they do. In graduate school, when I took an
advanced networking class, I was simply amazed at all that goes on under
the covers to allow us to communicate and the components to talk to each
other. To this day, I keep reminding myself when I think of the details,
"I am amazed any of this really works".

And when my insomnia sets in, I think back to networking hashing
routines, and that does it for me.
