When I was a kid I used to mess around in the woods and came across a logging site. The keys were in the bulldozer so I started it and took it for a joy ride. I couldn’t figure out how to turn it off so I left it running. Later I learned that diesel engines of that era had a mechanical lever that pushed on the injection pump to shut them down.

We still have a 2004 Honda CRV, we bought it brand new, paid it off 17 years ago, maintained it, and it still is perfectly reliable with 280k miles on it. At this point we bought a newer car because we got a really sweet deal on a 2020 Volvo and the Honda is our supply chain insurance policy and my airport long term parking lot beater. It has liability only insurance and it costs me nothing but gasoline and the occasional oil change to keep because I’ll just donate it to someone if it breaks down. I have gotten well more than my money’s worth out of that car.

Right now I’ll hire someone with a bachelor’s and pay their grad school tuition if they do well at an internship. A good IC designer takes a couple of years to grow no matter what degree or school they come from. I don’t want a simulation jockey, I need people who know the how’s and why’s of both the semiconductor devices and the end applications. I’m not going to spend $1M+ and 9 months of team time on a tapeout because someone didn’t question a result that looked to good to be true and didn’t know any better than to trust a buggy PDK. Semiconductor design is all about combining statistics, physics, communication theory, circuit design, system design, and pedantry. You practically have to be a lawyer to interpret a SiGe design guide.

Analog design as taught in undergraduate school is extremely incomplete. Most of it is aimed at embedded design or gluing together a series of opamps and making filters. Commercial discrete parts are really good nowadays, so most board level design doesn’t have to worry much about linearity, distortion, phase margin, transistor ft, resistor mismatch, or time delay. PCB design generally uses a few components with really good tolerances to build a circuit function. IC design uses a large quantity of crappy devices to build a stable circuit function. It’s an extra layer of methodology that isn’t there in undergrad, and it’s hard to learn on the job because the stakes are too high.

Curse of Oak Island. The narration is hokey and they probably will never find anything but I’m a sucker for big machinery, digging holes, and marine environments. Plus, the Laginas don’t seem to engage in personal drama or posturing. I’ve been interested in that place ever since I read the reader’s digest article about it.

My dad managed a paper mill when I was a kid and used to bring home a ‘log’ of paper towels sometimes- it was about 6 feet wide and we used them for picnic table cloths. They were usually a funny color because he would grab them from the scrap pile, and they would be the changeover paper from when they switched dye blends for the various brands they produced at the mill. They usually ground them back up into paper again, but they let employees take them home for personal use.

The machine that cuts the logs into rolls of toilet paper or paper towels looks like a bunch of chop saws in a line.

I had to have a lymph node removed from my face for a melanoma biopsy and it was entangled with my salivary gland. I was given scopolamine patches to control the production of saliva while it healed to control the leakage from the gland. They worked really well.
