  • Well, its $18 for a hot dog and a drink, and also the cost of labour and transport to get them to your door, and little bit for admin costs.

    So if, say, the delivery person can do one every 20 minutes, that’s $54 of revenue an hour for the company, minus, say, $10 for the actual food/drink items, $20/hr to employ the person, plus 3 x trips at, say, 5 miles per trip at like, 25 cents/mile for fuel and maintenance, so $3.75 for that… so about a 80-100% markup on cost for basic labour and expenses, which is where businesses generally need to be on markup to keep afloat.

    The other option is to go get one yourself I guess, but if you value your time the costs end up being approximately the same.




  • All current datacentre hardware is being run at power and density levels that hover somewhere between “operational” and “pile of glowing silicon slag”.

    I’m sure some enterprising Chinese companies will take all the surplus hardware and create underclocked “consumer-capable” versions for inference. I’d happily pick up a couple of cards that are 75% of cutting edge performance if they’re a hundred bucks a pop.


  • I posted this the first time around:

    Looking after your fridge is not a problem when you just have one fridge. You open it one day, oh shit it’s not working, you get it fixed. Done.

    Companies have hundreds of stores each with 10 or more fridges in them. Nobody in the store is keeping tabs on whether the temperature is set correctly to meet food standards, or whether the condenser is blocking up and full of fluff, or a bunch of other maintenance and administrative stuff associated with owning a bunch of fridges.

    Solution? Remote reporting and management. You can keep an eye on all 5000 of them 24/7, alert the store if there’s an alarm, call maintenance when there’s a failure , etc etc etc.

    The only mistakes made here is that they didn’t put their fridges on a secured internal network, and they didn’t update the software when Danfoss said they should .




  • I feel there has to be a “tinkering factor” in there, so that if that non-RF link is something constructed from spare parts and curious fingers it still counts to some extent depending on the home-brew component of the construction.

    Also distances over the internet are immaterial. Perhaps shifting to a module/component count would be better. For example, 2 radios on each end 100%. A radio, a self-built software modem, ((the internet)) , another self-built modem, a radio is still 80% HAM.


  • haven’t gone through the trouble of registering copyrights with the government or with copyright policing services,"

    This is country specific, of course. For example, in Australia the act of committing a work to media of any form is enough to register and assert copyright for that work.

    So as an Australian resident I am quite within my rights to assert the following immediately, with the legal backing of the Commonwealth of Australia:

    This post is copyright ©️ dgriffith. I grant the Fediverse and its users/instances permission to duplicate as necessary as part of the normal mechanisms of participation, all other rights are reserved.





  • One way, I set the numbers local, can’t be changed otherwise.

    Its simple (as am I), why does it need to be on the “cloud”???

    That’s fine when you have one fridge.

    Then you need to look after four thousand of them.

    Oh, it’ll be fine, we’ll just set things once while installing them.

    Oh look! New food, or efficiency, or store standards have dropped, now you need to update those settings in those 4 thousand fridges spread across the whole country. Well, we can do a couple of stores a day, I guess it’ll only take a month of a service tech’s time and travel costs to do it.

    Orrrrrrr… we could hook these fridges up to the Internet and do it remotely, and update the settings on those 4000 fridges before lunch.

    That’s the draw, convenient mass update. The main issue here is that they put the fridges on an unsecured network, and then on device auth was laughable, allowing any bored teenager with time on their hands to tinker with things.
