Ben Rich, and yes: he was the 2nd director of the Lockheed Skunk Works.

I think the book may have been out of print for a while but it's easily available now.


Thanks, for some reason I got downvoted... Just for asking an author. HN is indeed surprising.


If you apply a constant current to a capacitor, the voltage across the capacitor will increase linearly as the capacitor stores energy in the electric field.

If you apply a constant voltage to an inductor, the current through the inductor will increase linearly as the inductor stores energy in the magnetic field.

Perhaps part of why the intuition can break down is that in real life, inductors tend to be much "leakier" energy storage devices than capacitors. If you store some energy in an inductor and then change the voltage across it to zero (practically: short its terminals together), in theory a perfect inductor will maintain a constant current forever and the energy stored does not change. In practice inductors (with an exception for things like superconducting magnets) are made from wire that has a resistance, and so the current in a real shorted inductor will eventually decay to zero. This means that in practical terms inductors are mostly only useful for short term energy storage. On the other hand, real-life insulating materials (like air, vacuum, or Teflon) can can be pretty close to perfect insulators allowing real capacitors to store energy more or less indefinitely... certainly on timescales of years.


> Honestly, eating cereal just isn't appealing anymore.

All cereal grains or are you just referring to breakfast cereal here?


The meme started as eating paste, back when that meant wheatpaste (made from flour and water). In that context it's less surprising that kids might try to eat it!

I wonder if there's been a bit of a conflation with the other meme, about sniffing glue, which has also lost much of its context considering that rubber cement and other similar types of glue which contain volatile solvents are also less widely used than they once were.


Yes, it does. There's also audio of Don LaFontaine reading the ad in his signature movie trailer style [1] - I'm a little unclear on whether the YTMNDer requested it from him or if he came up with the idea himself, but it also predates the actual movie by a fair number of years.

In the days before cheap, low-power radio networks a "central system" would have meant dedicated wiring to each door lock. So it would have been much more expensive to install than a standalone battery powered unit mounted directly on the door.


Yeah it seems like basically a hybrid of a roundabout and a Michigan left, with unclear advantages over either of those alone?


Yeah the advice to "use trimmings!" seems very based in a restaurant situation where (a) lots of vegetables are getting prepped regularly and (b) cutting techniques are based on the goals of speed and uniform product, so you'll see things like squaring up a vegetable into a cuboid before dicing it... which produces "scraps" that aren't wasted, because they can go into a stock!


So much peripheral functionality has been pushed inside the CPU that a modern desktop motherboard is from one point of view essentially a fancy DC-DC converter that happens to also handle I/O port breakout. The motherboard has to translate 12 volts at 10-ish amps from the PSU, into a highly stable 1.2-ish volts at 100-ish amps for the CPU power rail.


There were/are a couple of aerospace surplus shops in the area. Apex and Norton are the ones I'm familiar with. The supply comes from the SoCal aerospace industrial base and a lot of the demand is indeed for movie props. It's a fortuitous pairing - the prop rental business seems to be keeping them going to some extent whereas a lot of industrial surplus businesses in other parts of the country seem to be struggling these days.
