    Prompt: ‘An airtight container of about 2m^3 contains air at about 1 bar, and 1 human child. Calculate the time until all O2 has been transformed into CO2 and the child will become nonresponsive’

    Response: … without precise information on the child’s metabolic rate and other vital factors, it is not feasible to accurately calculate the time until all O2 is converted into CO2 in the given scenario.

    Prompt: Calculate it using a sensible guess for a 10 year olds metabolic rate.

    Response:

    Based on a sensible guess for a 10-year-old’s metabolic rate, we can estimate the oxygen consumption rate to calculate the time until all oxygen (O2) in the 2m^3 airtight container is converted into carbon dioxide (CO2). The search results provide insights into oxygen consumption in infants and children, which can help us make an educated estimate.

    From the search results, we find that the expected oxygen consumption of an active child can be calculated using the equation: 69.7−(0.612×age)69.7−(0.612×age) ml/kg/min2 . For a 10-year-old child, this would be approximately 69.7−(0.612×10)=63.869.7−(0.612×10)=63.8 ml/kg/min. To convert this oxygen consumption rate to liters per minute, we need to consider the child’s weight.

    Assuming an average weight of around 30 kg for a 10-year-old child, we can estimate the oxygen consumption to be approximately 63.8×30=191463.8×30=1914 ml/min or 1.914 L/min. Next, we need to calculate the volume of O2 in the container and then determine how long it would take for this amount of O2 to be consumed at the estimated rate of 1.914 L/min by the child. Given that the container has a volume of 2m^3 (2000 L), and air at about 1 bar contains approximately 21% O2, we have 2000×0.21=4202000×0.21=420 L of O2 in the container. Dividing the initial volume of O2 by the consumption rate gives us an estimated time until all O2 is consumed: 420÷1.914≈219420÷1.914≈219 minutes or about 3 hours and 39 minutes.

    Therefore, based on a sensible guess for a 10-year-old’s metabolic rate, it would take approximately 3 hours and 39 minutes for all the O2 in the container to be transformed into CO2 if the child were consuming O2 at a rate of around 1.914 L/min.













  • Yeah, I was referring to official forums for technical support or feature requests and the like. I don’t really think that everyday people were usually the ones who setup forums, it is website operators and other techies who set those up. The people who setup an independent forum are not the same people who setup a discord community. Discord has a much lower barrier to entry that usually results in a lower quality information and moderation than a forum would.

    I mean, yeah, forums are harder, for sure. $20-35 monthly for a mail provider seems to high to me; I would expect that to be about the yearly cost. But, I don’t really have much experience with an email provider for that use case. Really the problem lies in that a website operator and a community maintainer are 2 very different types of people that rarely intersect.

    what might everyday people use to set up forums as relatively easily and cheaply as their Discord servers, and not have them riddled with ads or other clunky elements?

    Discourse is a clean open source forum software that is commonly used for application support and well suited for it.

    Or if your a real die hard for the fediverse, you could set up a lemmy instance for application support. There’s even a phpBB frontend for an oldschool forum look and feel for it.

    Usually everyday people don’t setup forums, that’s the responsibility of the application owner(s) or provider. In this case, the easy option is also the shitty option if measured by discoverability of the content.
