There’s planned downtime every night when we turn on the Roomba and it runs over the cord.

        Caching is like accruing debt for CPU time between network connected devices. Let’s suppose the following:

        Computer X is talking to computer Y with a 32mb cache on each side. They both need to be involved in the following math that’s about to take place. Computer X is doing the math, and Y is supplying the data, but also manipulating the return data for some data it will send in the future.

        This is all well and good if this a 2-endpoint network. Computer Y will be ready for X’s data at any time. However, the internet is not 2 endpoints, and both X and Y are talking to a bunch more computers about totally unrelated computationally networked tasks. So now Computer X can’t send data to Y or vice versa because they’re busy. X doesn’t have anything to do so it works on the next problem it has lined up for Y and critically, adds this data to a cache marked “for Y, do not delete.”

        And now you might see how “caching” a varitable niagara falls of data (cloud compute requirements) to the wider world would get rather bloated, literally running up computational debt until storage is exceeded.

        EDIT: To nail home the debt analogy, this debt also accrues interest in the form of the CPU cycles needed to manipulate data within the cache, including both retrieving and storing that data, although this often happens with any networking whatsoever so it’s only measurable in a case where the cache is so bloated.

    I have a friend who constantly frames problems by blaming someone … anyone

    The concept of accidents, unfortunate events, chance or unplanned events is a foreign concept to them. They constantly believe that any and every problem in the universe is caused by someone doing something intentionally or ignorantly.

    I can always count on them when there’s a problem … that they’ll automatically blame someone.

      That’s almost as annoying as the armchair psychologists who don’t believe in accidents. No, I really, truly wanted to break my favorite glass, gather the pets in another room, then spend time sweeping and vacuuming up shards. FFS…

      You know Carl Hiaasen? He wrote this in 1997:

      Bodean James Gazzer had spent thirty-one years perfecting the art of assigning blame. His personal credo - Everything bad that happens is someone else’s fault - could, with imagination, be stretched to fit any circumstance. Bode stretched it. The intestinal unrest that occasionally afflicted him surely was the result of drinking milk taken from secretly radiated cows. The roaches in his apartment were planted by his filthy immigrant next-door neighbors. His dire financial plight was caused by runaway bank computers and conniving Wall Street Zionists; his bad luck in the South Florida job market, prejudice against English-speaking applicants. Even the lousy weather had a culprit: air pollution from Canada, diluting the ozone and derailing the jet stream… A series of unhealthy friendships eventually drew Bode Gazzer into the culture of hate and hard-core bigotry. Previously, when dishing out fault for his plight, Bode had targeted generic authority figures - parents, brothers, cops, judges - without considering factors such as race, religion or ethnicity. He’d swung broadly, and without much impact. But xenophobia and racism infused his griping with new vitriol.

    the ISP i started my career at in the mid-late 90’s sold “T1” access to businesses and had a ton of csu/dsus and a few portmasters with modems setup at 56k. a couple hundred customers. He even wanted to be a dsl clec.

    Our upstream was 768k.
