  • 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.







    • 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.
