Ground is a very relative concept in electronics. You are correct about earth ground, but if the case is unplugged and you touch it, you are still grounding yourself to chassis ground. Chassis ground is the important one for this since the danger isn't electrocution (assuming the PC is unplugged) but electrostatic discharge (ESD) that can damage components.

This is still a massive simplification of the concept of ground.

Probably not as many as we'd like to think. I recently got to run a few days of tests at Lawrence Livermore National Labs with an absurdly massive laser. At one point we needed to bring in a small speaker for an audio test. It took the lab techs and managers about two hours and a couple phone calls to some higher ups to make sure it was ok and wouldn't damage anything. There's so much red tape and procedure in the way that I don't think there's an opportunity to just fuck around. The laser has irreplaceable parts that people aren't willing to jeopardize. Newer or smaller lasers are going to be more relaxed. This one is old enough to be my father, and it's LLNL's second biggest single laser iirc. And they are the lab using lasers for fusion, so they have big lasers.

Yeah, I have a couple over 800MB PNGs that I can only get Gimp to open properly. I need to look into pyramidal TIFFs.

Holy hell. Stop spamming the same picture on a dozen communities.

And if there's ever a brand integration, he'll spout their marketing drivel uncritically and try to pass it off as science. I can't trust him anymore.

I've done it. It cooked well enough.

Why are you making it weird and tied to race. I'm not thinking about the cat's genitals. That woman isn't, and her cats sure aren't. You are the only one thinking about cat genitals in this situation.

There's a similar chip that makes a door chime ding-dong sound. M581A

I forced myself to learn to touch type when I switched to Dvorak. I started out with stickers on the keys, but when that laptop died a couple months into the switch, I never got another sticker set, so almost none of my keys had the correct labels, so looking at them wasn't a good option. I'm definitely as much faster typist now, and I only partly credit the Dvorak layout.
