    Overwatch has a system of player endorsements which I feel helps with toxicity and could have helped with bots.

    This article has some examples of power and energy capacity: https://en.wikipedia.org/wiki/Battery_storage_power_station#Largest_grid_batteries

    In December 2020, Vistra Energy's Moss Landing Energy Storage Facility, on the site of the Moss Landing Power Plant, was connected to the grid. At the time, the 300MW/1.2GWh facility was by far the largest in the world

    From this and other examples in that table, the most common power to capacity ratio is 1:4. Which means that the battery storage can fully discharge in 4 hours.

    I'm surprised that Li-ion (which uses expensive metals in the cathode: Nickel, Manganese, Cobalt) is a more popular chemistry based on the amount of installed capacity compared to the cheaper lithium iron phosphate chemistry (LiFePo4). The only drawback of LiFePo4 is that it is less energy dense (ie, more volume and mass per 1KWh), which makes it less suitable for use in electric cars (though Tesla has started to put LiFePo4 into their standard range cars). The extra volume and mass does not matter for static storage. Compared to Li-ion it should be the chemistry of choice for grid energy storage: lasts longer, cheaper, safer: https://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery#Advantages_and_disadvantages

    The continuous power output of a lithium battery has a connection to capacity. A battery can typically charge and discharge in 20 minutes (excluding the slower charging ratr when the battery is almost full). For example a battery with capacity 100 Wh can discharge in 20 minutes at power output of 300W.

    The discharge power/current is often expressed as a multiple of capacity and 3C ( 3 times capacity) is typical for li-ion and LiFePo4 batteries.

    The charge/discharge rate gives you the limit at the battery cell level. At the pack level, the connections and power electronics may not be sized for this maximum power. So likely a battery pack with 248MW of power would be providing this much power for more than 20 minutes.

    I agree that the article would be much more useful if they talked about both installed capacity and power.

    One example is steemit.com - the ranking of content is based on how many tokens each voter holds. Whenever I looked at it I had an impression that all activity is focused on token farming and not on great content curation. Lots of meta content talking about how to earn tokens.

    That's what arbitrary milestone numbers are for - to remind you about it.

    The economics of truck package delivery is that 1 package is ~$1. That's how much Amazon pays delivery companies. Would automated drone delivery be able to beat that if launched at scale?

    One suggestion: it would be easier for me to read if the nested phrases were marked with parentheses or dashes instead of commas. Like so:

    But who thinks that crime and extremism arise from the “structures” of this country even from and especially from their immediate surroundings accuses and alienates their main ally in the fight against racism.

    Is the building built out of shipping containers? Is that a common practice? It is probably hard to fight fires in such setup compared to a regular datacenter building.

    An excerpt:

    Today, the Russian Criminal Code no longer contains article 159.4, under which brothers Oleg and Alexei Navalny were convicted.
    The Constitutional Court of Russia found this article of the Criminal Code to be contrary to the Basic Law of Russia. In 2015, this article of the Criminal Code was decriminalized and removed from the criminal case.
