  • There’s no reason your clients can’t have public, world routeable IPs as well as security.

    There are a lot of valid reasons, other than security, for why you wouldn’t want that though. You don’t necessarily want to allow any client’s activity to be traceable on an individual level, nor do you want to allow people to do things like count the number of clients at a particular location. Information like that is just unnecessary to expose, even if hiding it doesn’t make anything more secure per se.



  • That happens literally every night though and wind also doesn’t blow 100% of the time.

    Very true, but the fact that wind blows often and there’s also varying amounts of direct sunlight during the day already massively decreases the amount of storage required for a grid. You don’t need the capacity to cover 100% of energy usage, sustained, like you suggested earlier. Especially as grids become (geographically) larger and smarter — we need wind and sun somewhere to cover energy needed elsewhere — it doesn’t have to be localized. Plus solar output obviously peaks during the day, when demand is also highest.

    Renewables make up a trivial* amount

    The percentage is absolutely not trivial today. Especially considering there are multiple large grids today that can easily sustain 50%+ renewable energy over sustained periods. And 30% by 2030 is a lot, though of course it could be a lot better.

    and as we phase out fossil fuels, the requirement for energy storage is going up drastically.

    Yes, no-one is arguing otherwise.








  • Well yes and no. Market cap is the total value of all shares for the particular stock combined (not including those held by the company itself). The value of each individual share is determined on the market. No-one directly “owns” this value, since the whole point of stocks is to distribute ownership, so no-one including Apple as an entity “owns” their market cap entirely. If that were the case, there would be no trading, and ergo no value to the shares, and the entire idea of a market cap no longer applies.

    Individually though, the value of shares is of course very real. If you own shares and the stock is liquid (as in: there are people willing to buy), you can sell those shares for real money whenever you wish, at the current market price. Unless you want to sell a substantial amount, in which case you may run into trouble finding buyers and / or create significant downward pressure on the price.








  • If you read the original report, it says that it basically just displays a fake banking login page. It also says that it requested accessibility service permissions, which makes me think maybe it brought up the fake login pages “in the right moment” (as in as users opened their banking apps) to make it more convincing, even though the article doesn’t specify that.

    Either way, IMO the problem here is clearly with the Play Store allowing this app in, and not with Android’s security itself. These apps are misusing the accessibility service system, which is obviously necessary for a ton of important use cases (and of course also requires the user to grant very explicit permission). The fact that the accessibility services are a thing doesn’t delegitimize Android’s security improvements over the years.
