Slight devil's advocate episteme: what about an even-further generalization? How about: the market is the computer? Not only is the network essentially imbricated with/in the market, but recognizing the market in the role of the computation also means recognizing the roles of all of the different functional components, not just the mechanical/computational "atoms". Basically, I think that thinking this way lets us tr…

That fails the sniff test. Markets are made up of agents that want things. Computers only want what humans say they should want, so computers are simply the agents of humanity. You can't abstract out supply and demand, at least, not forever. Abstraction is something you do to things so that you don't have to cognitively deal with them, they're predictable. Humans will act predictably for as long as it makes sense for…

I think there's some questions to be asked about this, but the main one is this claim:

> Abstraction is something you do to things so that you don't have to cognitively deal with them, they're predictable.

The word "predictable". What does it mean to be predictable? Are periodic trends with micro-variations considered to be predictable? In that sense, might it not be possible to Fourier-decompose some time-series into a sufficiently-"predictable" set of frequencies?

But actually, I'm not even sure if this qualification is needed. If an abstraction is basically just a way to treat a bunch of events as a single idea, then what if the abstraction isn't something telling you how you should act, but instead something telling you how you should react?

Another assumption, I think, is that the market is human, i.e. because there are affective dimensions and bounded rationalities in the economy that make it unpredictable. This is true right now, but is that inherent to the market? You can argue that even an automated agent has "humanity", in the sense that it is essentially imprinted with their creator, but how much longer will this hold? It's asymptotic, but won't there be a threshold at which the humanity of machines made by machines, with many steps removed, becomes negligible?

but it is not enough for cases requiring sub-millisecond latency and incessant availability: Fields such as IoT metric processing Why would IoT metric processing be latency sensitive? Whether my thermostat processes the temperature in 3 milliseconds or 30 milliseconds seems immaterial.

true for private IoT, but the industrial IoT is orders of magnitude bigger and comes with a host of use cases where machines operate at 100 to 1000 Hz cycles - and for stopping your 20.000 rpm milling machine or opening your pressure release valve 30 milliseconds makes a lot of difference.

Why the hell would an investor care about some technical performance nuance that could easily be implemented via setting up some Cloudfront distributions?

Did she ask about your cache headers as well?

Please fix the scrolling under mobile Safari, it has no momentum.

And chrome.

Thanks for the hint, will do (seems to be iOS specific, hmm)

OH, so you're saying in a % b = c it refers to b rather than to c? That would make sense... I always just read it as "remainder" in which case it would refer to c...

I don't think speech is mathematical, rather the opposite if anything. In a equivalent b modulo c the c is the modality , the property or condition we are interested in. The use in English is different to math's, because Natural languages are like mathematics modulo the rigidness . A category theorist would say isomorphic upto .

I had looked up "modulo" in a couple dictionaries and only seen the mathematical definition. I hadn't thought about it as being related to "modality", interesting.

Is it really a self-driving car if it needs a network connection?

Conveniently all of your users have 90s era supercomputers in their pants. Shame we're wasting that compute on nonsense.

Maybe borrow from physics to call it the Egress Horizon.

I think for most cases, "on the edge" means some devices on the sites of those IOT sensors/small collection machine installed. In compare to "on the cloud" which means on the server hosted by Amazon/Azure etc.
