  • Yeah - the dose is the poison (if you drink enough water it becomes toxic), so if you are talking precisely you need to describe the concentration of a substance in which it is likely lethal to a person, and that’s typically expressed as mass of a substance per mass of bodyweight. A lot of the time you will also see this expressed as an “LD50” value; the dose at which you’d expect 50% of people to die. This accounts for the fact that people’s metabolisms vary quite widely.

    ~1ng/kg ~= 0.08ug for a typical (~80kg) person, which is a very tiny amount - whatever you are talking about is incredibly toxic.



  • Sounds like a great idea - I suspect the biggest obstacle will be finding someone at the home who is confident enough in what to do with it to be willing to accept it.

    I’ve run into similar issues with schools where they are hesitant to accept donations of things like that because they don’t want to be saddled with equipment they don’t know how to use and maintain. Maybe worth seeing if you can raise a bit of money for a second hand Xbox or something?





    • it takes engineering time which is not a trivial cost - accounts and identity for large orgs tend to be a lot more complex than you might think - there will likely be a few different identity stores, and multiple systems that query those stores; making sure every possible permutation works correctly can be a bit undertaking
    • It adds additional load to their support teams which is very expensive

    The support one is a real killer for a lot of places; I’ve worked with a place that had a few million paying customers, and ~half of those were in a tier where a single 30 minute support call would completely negate any revenue that that customer would bring in for the year. Email support was slightly less expensive, but would still be a significant proportion of your annual profit




  • On top of the logistics of moving massive amounts of water around, flood water is typically highly contaminated - by their nature, floods sweep up everything in their path, which typically will include things like:

    • Soil and sand (a massive pain to filter out)
    • Agricultural run off (manure, pesticides, fertilizer, …)
    • Raw sewage (from treatment plants that tend to be near waterways, or just from damaged infrastructure)
    • Industrial wastes (from existing plants, or old contaminated sites)

    Infectious disease is a major problem after a flood, partly because of infrastructure damage but also just because so many people will have come in contact with contaminated water - you don’t want to irrigate your crops with flood water, much less drink it

    Edit: from the other answers, I’m probably wrong - maybe don’t trust this as correct

    I don’t think so - HDMI and Display Port actually carry their signals in the same way, so the adapter is basically just converting between two plug types without any smarts in the middle.

    In theory you could get an adapter that is badly made and adds some noise to the signal or something and forces the monitor to down-spec it’s signal but I’m not sure how likely that is to come across.





  • There is one standard way to cast fireball - it works, it’s cheap, it very rarely backfires, it’s in all the textbooks, everyone knows how it behaves - but sometimes you sit down in a tavern next to another wizard and you just know before they even open their mouth that they are going to spend the next twenty five minutes telling you about how they learnt this alternative way to cast it and it’s taken a bit of practice but they can just about cast it as fast as they could before and how it’s so much more ergonomic or whatever


  • Debugging spells is just as much a dark art as spell crafting itself. When I was a young apprentice we didn’t have as sophisticated tools as you do now; you had to make sure you noted down your intermediate runes correctly and use those symbols to divine some meaning from the ashes of your failed spell. One time I mixed up my notes with the symbols of a different spell and when I sprinkled the ashes on the stack I was stuck speaking in tounges for a week.

    These days of course you can summon a lesser demon to freeze your spell and ask it about the state, but the demons can be tricky and it’s easy for novices to make a mistake and allow the demon to run amok - makes a real mess of the lab.
