What's up with the computer at LLC? Someone
installed two different

need to take off some stuff from it for the screening tomorrow...
Anka, Thursday I replaced the Apple monitor with a slightly larger
monitor, it has a higher screen resolution (1920x1080 vs. 1680x1050) and
is a bit bigger and should have good color reproduction & better viewing
angles, it is IPS. If not the old monitor is near the GCEA computers. I
also replaced the M.2 SSD Linux install on the Hackintush with a regular
2.5" SSD drive with Linux, the previous M.2 install was flaky,
frequently giving me cryptic messages and not booting.
But I experienced some extreme weirdness when I was messing with the
computer which I meant to report to the list, but my brain don't work so
good any more, and it was never particularly great in the first place,
so it slipped my mind when I got home.
First, I wanted to use the desk lamp with the CFL bulb to see what I was
doing under the table, but it wasn't working. The power strip was
plugged in near the Cat 5 jack, so I tried plugging the power strip into
the wall socket near the hackintush, no joy. I tried another power
strip, no luck, then I realized that the lights on the power strips were
not lit up, _*BOTH*_ of the wall sockets are dead. I astutely noticed
all the extension cords bringing power from outside of the office, so I
plugged in to an extension and finally was able to get a light on.
So I got on my belly and grabbed the Hackintosh and got a pretty
substantial jolt even though I had flipped the switch off on the power
supply. So I pulled the Hack's power cable and continued to get little
shocks most whenever I touched the computer's body. I have NEVER had
anything like this happen in a close to 30 years of mucking with
'puters. I asked Dante if concrete conducted electricity, and he didn't
think so, but then he looked it up and told me that concrete is an
excellent conductor.
My guess is that whoever installed the electrical outlets,
cough...Gerald...cough.. mucked things up with the ground and basically
the whole office is now acting like some sort of ground. I actually
don't know shit about electricity, I discussed my experience with Yar,
Jenny & Rob, and they all said this sort of thing shouldn't be
happening, but they were a bit out of their depths fixing it, and I
should talk to my friend...Gerald. With friends like me who needs
enemas? Maybe Jake or Marc have a theory, I'll CC the sudoroom list and
the building folks.
I'm heading to sudo room today and will poke around. I've had the same
thing happen when multiple computers are plugged in and not grounded
properly, e.g. in old buildings where the ground is just hooked to the
plumbing. Back in the day you would get punished by the network for
showing up late to the LAN party since it was physically painful to
plug in the coaxial ethernet plug if many other computers had already
been plugged in.
