I'm still working on developing a habit of writing regularly. I love it when I find a personal blog post that perfectly solves a problem that I have (especially when that blog post is essentially the only resource for a very specific problem) or explains a concept better than anything else. So I'm trying to do the same for others for things that I know about.
More people should share what they know.

Mapping Capslock simultaneously to both ESC and Control solved this problem for me. It might not be your piece of cake but it definitely improved my vim experience greatly. See for example (I'm not the author) https://www.dannyguo.com/blog/remap-caps-lock-to-escape-and-control/

> I remain in awe that we trust the very cheapest plastic under repeat load and thermal cycling to form a -40dB seal, turning 700W into 70mW
It's the metal grid in the window (with holes smaller than the wavelength of the microwaves), and the metal shell of the cavity, not any "plastic." The same reason the metal grid works is why there doesn't need to be a perfect door seal. As long as as the gap is smaller than the wavelength of the microwaves, it's fine.
> Also, it seems that the outer metal shell of the device forms an active part of the circuit, so if it isn't plugged into a grounded outlet it sits at lethal potential.
The shell doesn't sink RF, it reflects it. GFCI outlets (required in many areas for kitchen outlets) trip at 5mA differential between hot and neutral. No appliance is designed to sink current into ground unless there's an electrical fault.
> Then there is beryllium oxide in the thing...
Beryllium oxide hasn't been used in microwaves for a long time, and it presents zero risk unless the magnetron is smashed.

Edit: They can interfere with WiFi because a microwave could leak a tenth of a percent of its nameplate power and it would overpower your access point by anywhere from 1x to 10x. Access points can, on certain bands, have radios up to ~1W, but 125-250mW is much more common.

Was the number used to sign up for, and receive communications from credit card companies? Is the ban related to signing up for +100 cards?

There was a post on HN once for a hack to do the same on Linux

Just happen to read another thread "my seatbelt rule for judgement" https://www.dannyguo.com/blog/my-seatbelt-rule-for-judgment/ ,I can't agree more.
Before you make any judgement about anything, you need to learn about it. In this case, go visit Xinjiang, talk with natives, see with your own eyes, and then you know who's telling lies.
