What's the point of even ordering through the app then?

1. It's still fairly convenient; I find it easier than verbally ordering. 2. I believe it's the only way to get curbside pickup instead of going through the drive through. 3. It functions as a loyalty card; there's always $1 large fries, you get a free coffee drink after every 5, etc.

The app remembers your previous orders. If you order the same thing each time, you just press the previous order to order it again. Done in like 5 seconds.

Like any other e-commerce store, you can add stuff to your cart, and then choose not to check out. And it is typically during the cart-adding process that you find out if a product is actually available for purchase or not, as opposed to at checkout time. I would assume that's what is happening here, which means it's not actually affecting any in-store operations, just (as the author says) probably messing with their…

Isn't that something that Google has been accused of before, adding things to carts, and then leaving?

I am sure that lots of price scrapers do this, including Google..

Meanwhile, Chick-fil-a is running Kubernetes at the edge for equipment, POS telemetry, and ML. https://medium.com/@cfatechblog/bare-metal-k8s-clustering-at...

Their tech stack is far more bleeding edge than I would have envisioned. I wish they gave an idea of why they chose to use k8s at the edge. I can see how containers are useful for deployment, and the fail-over built into Kubernetes is really nice, but I'm shocked that's the simplest/best way to do it at the edge. I would have expected some VMWare product, just because it's "enterprisey". Shame on me for judging.

Deployments and monitoring are probably another draw. Same tools server and edge side.

Another project to keep an eye on is AWS's Greengrass which has a bunch of capability overlap, but a bunch of new ideas for edge and fog IoT also. I had a mixed experience with it but at least some ideas bear borrowing.

Back in the day I worked in a dairy company as an IT guy. When the RFID antennas would need a reboot I had to go to the deep freeze storage (-40 Celsius), walk in with a ladder, climb the ladder, switch off and then on (IT crowd style), wait to see the green light bleeping, and then climb down and leave as fast as I could. The whole thing would take 40-50 seconds (I was counting EVERY time). I couldn't wear gloves, b…

I used to walk to school in sometimes very cold weather (-35 Celsius). Once, in order to try preventing the inside of my nose to freeze, I put my scarf over it. The scarf froze very quickly and I ended up with ice around my neck... Now that I’m thinking about it, I wonder how people will manage masks this year with COVID in cold countries. TL;DR: don’t put a scarf over your nose in very cold temperatures.

I'm Canadian and we get -35 temperatures for at least a few days every winter. This doesn't make sense to me. Of course you should put a scarf over your nose. At those temperatures , exposed skin freezes very quickly so you need to cover all your skin or you'll get frostbite.

I've never had a problem with a scarf freezing stiff like you describe. They build up ice crystals of course, but they don't interfere with air flow and are easily broken.

The biggest problem I expect from wearing a mask in the winter is that they'll get damp quickly because the cold temperatures, and perhaps having a scarf over top, will prevent moisture from evaporating.

I usually ride my motorcycle through winters in the upper midwest. No, it's not Canada, but at highway speeds in freezing weather it gets cold very quickly. I can't cover my whole face with cloth, or my breath will fog up and freeze over my glasses and visor. I apply vaseline over all of my exposed skin before riding. It does a great job of protecting my skin. I also do this when bicycling through extremely cold weather.

Would a coronavirus survive in these conditions anyhow? Or, remain transmittable?

Last I heard the coronavirus survives a lot longer in freezing conditions than at room temperature.

Fruit flies or house flies? The difference matters.

Is one worse than the other for some reason?

Fruit flies eat fruit and are harmless (if gross) to ingest. Black flies eat feces and rotting flesh and transmit all manner of diseases.

NTP is fine but so is pulling time off a server header if it's phoning home to report status.

Not that it matters for ice cream, but NTP can compensate for latency better than HTTPx can.

It's also easy to implement since it will be integrated into the OS of the ice cream machine already.

This 'bulking up with air' is most evident if you go to the yogurt or cream cheese section and look for the Yoplait Whips or Philadelphia Whipped containers. It's the same product, just as a foam, and seems to be marketed as a healthier alternative where users choose a satisfactory portion by volume, not by calories or weight. And while I think the whipped foods are stupid, I don't think that packaged food sellers ar…

It's not entirely true that regulators haven't plushed back: in the USA, there's a minimum amount of cream required before the vendor can call the product "ice cream". The products in that category that have been puffed up with air (and don't meet this minimum) get sold as "dairy desserts". (I don't work on the food industry, so I won't be shocked if I got details wrong.)

Which is exactly why McDonalds menus list "cones" and "sundaes". Not "ice cream cones". It's a frozen dairy dessert that is not legally ice cream. To be fair, McDonald's version is superior to any other fast food frozen dairy desserts that I've had.
