      I keep seeing this term but I have no idea what it means ?

      and what does it actually mean in practice. for example, what it can actually do, it seems to only be used for algorithms and such. not personal computing. I assume I don't understand because I'm unfamiliar with Quantum mechanics

    2. Why does this happen?

      A photographer I knew passed away, and I was trying to see if there was any information. This was the top result I got on google. The part after the ellipses says “killed in a plane accident in Pantanal.”

      He did not die in the plane accident! That’s another piece of Brazilian news, about the architect Kongjian Yu. The search result is even tagged with Yu’s Sponge City/Cidade Esponja.

      So why is this showing up for a post summary about José Bassit? There’s nothing in the post comments or the post itself saying anything like this.

    3. What's a question you could ask to determine if someone is an expert in your line of work?

      For example, I'm handy with a lot of stuff. I could change an outlet in the wall no problem. But if asked by an electrician what gauge Romex is safe for what amperage, or what color direct bury...

      For example, I'm handy with a lot of stuff. I could change an outlet in the wall no problem. But if asked by an electrician what gauge Romex is safe for what amperage, or what color direct bury Romex is, I'd have no idea (from the knowledge I walk around with day to day).

      I'm curious what other random facts people may know from their line of work that quality them as more knowledgeable than your average goose joe. Or to paraphrase, walking around knowledge people wouldn't know unless they googled it, or worked/were very knowledgeable in your field. And how many of them I (or others) might know.

      To start from my job:

      Q: Under what circumstances would one want to withhold the administration of vasopressors (Epinephrine) in a cardiac arrest?

      A:

      When the cardiac arrest is due to hydrocarbon intake, e.g. huffing spray paint

    4. Could a space traveler accelerate at 1g forever?

      I was reading this Reddit post and was curious about whether the passengers of this theoretical spaceship could experience 1g of acceleration forever assuming the ship has an infinite fuel source....

      I was reading this Reddit post and was curious about whether the passengers of this theoretical spaceship could experience 1g of acceleration forever assuming the ship has an infinite fuel source.

      They shouldn’t be able to pass the speed of light relative to an outside observer, but is there some phenomenon where the passengers can feel like they are accelerating forever?

    5. How to calculate how long a large project will be delayed? How likely it will be completed at all?

      I'm talking Really Big Projects. NASA plans to have astronauts skinny-dipping in Shackleton Crater by 2030. Norway wants to build the first ever commercial ship tunnel, done by 2030. That's the...

      I'm talking Really Big Projects.

      NASA plans to have astronauts skinny-dipping in Shackleton Crater by 2030. Norway wants to build the first ever commercial ship tunnel, done by 2030.

      That's the level I'm talking about.

      And also, I'm not talking about cost overruns or resource requirements, or anything like that.

      I just mean, really big, really public, engineering projects -- typically chock full of political complications -- get announced in the news, like ...

      "NASA to build Super-Duper-Big Telescope on Olympus Mons, for $8B, by 2034"

      -- and everyone knows it's actually going to cost 6-16x that amount, and be ready to use in the late-2040s ... assuming it gets built at all.

      I want something vaguely formulaic to calculate how much and how long it will actually take NASA to build that telescope.

      Back before he became universally hated, it was kind of a meme-level joke that Elon Musk was already living on Mars time, so all of his project-completion estimates had to be multiplied by 1.88 (to convert from Martian back to Earth years). The funny thing, as a rough guideline ... that was actually a pretty reliable formula.

      I want something like that formula, but given a bit more thought and research, maybe some optional variables to take into account the project circumstances.

      There are plenty of studies (I've been looking) that seek to identify and calculate the causes of large-project delays and cost-overruns, and how to minimize/avoid them. But I'm not trying to rein in the delays and overruns ... I just want to have a way of semi-realistically calculating, right at the start, just exactly how badly people are underestimating the timeline for building their Big Shiny New Thing.

    6. How linked is an account to the original invite code?

      I tried looking through the docs but couldn't find an answer to this question: What is the nature of the link that is established to the sys-admin and devs of tildes for an account and the invite...

      I tried looking through the docs but couldn't find an answer to this question: What is the nature of the link that is established to the sys-admin and devs of tildes for an account and the invite account?

      as in, do they store the invite code that I used to create this account permanently and will be able to link that invite back to the issuing user? so that my account and the issuing user will always be linked in that way?
