Sleep as Android has a CAPTCHA mode that prevents you from shutting off the alarm without some form of verification, like solving a math problem or scanning an NFC tag or bar code.

I struggle mightily with mornings and have been late to work countless times because I can unconsciously shut off my alarm. But with the CAPTCHA mode I can't shut the alarm off without physically getting out of bed, carrying my phone into the other room, and scanning an NFC tag. It's been a life saver.

I haven't seen such a feature in any other alarm app.

Same issue here, I'm being automatically logged out of my lemmy.world account in Firefox. If I refresh the page even immediately after logging in, I'm automatically logged out.

Genuine question: if they're airtight, how do oxygen and CO2 levels remain livable? Spacecraft and submersibles require oxygen supply and CO2 scrubbers to keep occupants alive.

I suppose what trips me up is that my brain sees the concepts of "airtight" and "ventilated" to be in conflict and I am seeking further clarification than what has already been provided.

I guess this is just a looser interpretation of "airtight" than what I've previously experienced in life. In my experience, "airtight" means "zero exchange of air in or out", but this setup is a controlled process where the only place air exchange occurs is through the heat exchanger. However, from these descriptions, it's not the same sort of "airtight" as what I'm accustomed to. Not trying to say that anyone is incorrect, just that it's different from what's familiar to me and that's why I was confused.

It's most likely water. The two main chemical products of fuel combustion are carbon dioxide and water vapor. The vapor condenses and drips out of the exhaust.

Take a look at this post, seems likely that you're seeing the same issue https://lemmy.world/post/1364490

Yeah, but the movies I purchased in HD are now only accessible in 480p. So technically available but not really.

I'm not following what do you mean when you say they force you to use their DNS. How does their DNS service relate to having a domain registered with them?
