The crazy thing I did to fix Yosemite performance

IBM made the first hard drives out of red paint. I mean like the
paint they use on the golden gate bridge. I Am Absolutely Serious.
But that kind of paint tends to clump up, so they were filtering it
through ladies' nylon stockings. (Facepalm).
It didn't occur to me until just recently that they could have used
Jeweler's Rouge. It's the same Ferrous Oxide (Fe2O3) as used for red
primer paint, but the particles are very very fine. It's used for
polishing optical glass, and is quite cheap. It's made by baking a
chemical preparation of Oxalic Acid and a few other things in a
Quite likely whoever made those first drives for IBM wasn't familiar
with making telescopes so he just bought a can of paint at his local
Al Shugart's first disk drive business didn't work out, so he put his
company under then, for a few years, operated a liquor bar in Santa
Cruz, California. Eventually he founded Seagate. I'm not clear
whether he figured out a better way to make the drives, or perhaps the
introduction of the IBM PC made it easier to sell them.
The Navy was all over me like a cheap suit to accept the Naval Reserve
Officer's Training Corps scholarship when I graduated high school in
1982. Some jackass enlisted man rang me up at home one day to say
"How can you know what the Navy is like if you've never tried it?"
"Listen I grew up in the Navy I know more about it than you do."
I did interview for the scholarship, but the Captain who conducted my
interview said that my interest in Physics suggested that I'd make a
great nuclear submarine reactor. I am quite claustrophobic so I
turned it down.
But had he suggested I run aircraft carrier reactors, I likely would
have accepted the scholarship. On the surface of the ocean, one has
the chance of survival by swimming through burning jet fuel, you see.
I often wonder how life would have been different for me, had I been a
Naval officer like my father. He would have been quite proud of me.
I gave the eulogy at his funeral. He's at rest in Willamette National
Cemetery now, just south of Portland Oregon. That's one of the
reasons I moved here, so I could be near my father, and honor his
service to our country, and to the world.
Just one last off-topic word:
My father felt that the entire American military was a whole bunch of
total slackers. He really did. He had quite a lot of respect for the
Soviet military. He wanted very much for them to be our friends, and
wanted very, very much to avoid ever having to shoot at them.
One day while standing watch, my father looked through his binoculars
to see a Soviet sailor looking right back at him, as their ships
passed in the Mediterranean. Dad waved at the sailor. The Soviet
seaman put down his binoculars, carefully looked to the left and to
the right, stepped into a doorway so as not to be seen by his
... and waved back!
