Quip worth thinking about[1] from the twitter thread[2]:

Not my field, but edible gums (guar gum, or xanthan gum for example) is "plastic" (adj.). Gums are used more and more, AFAICT as a consumer; presumably to allow products to be bulked out with air. Basically take anything homogeneous, add gum, add air, create a foam. Basically like an Aero bar but with way smaller bubbles. You just cut a quarter (I'm guessing on this figure) off your ice-cream ingredients by weight an…

> "having the coleslaw tub be much wider at the top, or putting everything in a wide plastic skirt so the box is 20% bigger than it needs to be" These days the trend seems to be to reduce the packaging, at least here in the UK. "Same size - less packaging!". So it seems like reduced packaging and distribution costs, and perhaps fitting more onto store shelves, outweighs any extra sales from customers who are fooled i…

I think there are two things, one is a preference with some consumers towards less packaging (given two products about the same cost and one looks like less packaging I'll tend to pick that) and the other is there's been a lot of talk about taxing single use plastics so I've wondered if they've been trying to alter the supply chains before that point.

I actually froze my hand inside an ice cream machine like this when I was a teenager working fast food. I hit a standby button instead of the off switch. (I was too tall to see the off switch and was never trained.) I spent two weeks in a burn unit while they healed my hand with magic synthetic sin grafts. Today you can’t even tell which hand got frozen in there.

Woah, how cold are these things that you would need skin grafts like that?

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, because ladder/switch. I was wearing all other gear though. Touching anything (aluminum ladders get cold very fast at -40)(so are walls, switches, everything). I did this process a couple of times wearing just jeans and tshirt. In that "less than a minute" my clothes would freeze solid, the wool was hardning and it felt like wearing a plank. Same with jeans.

In other cold related story, I was in a "cold country", out in the open, -25 Celsius, my phone rang, my gloves didn't have the electro-thingie so I couldn't "slide to answer" so I too my glove off, answered, talked for 60 seconds. Then I went to a warm pub, and after 10mins I could bend my fingers again.

Yes cold can .... you up badly in seconds.

MCD optimise for speed and throughout though.

Throughput of a broken shake machine is zero.

And yet people drive cars that need to be serviced etc. out of action for hours at a time.

Said another way: - You have a system whereby every instance has a 75%-79% uptime. - Each instance's 21%-25% daily scheduled maintenance window can (generally) be arbitrarily-scheduled by the ops team. How do you near guarantee that there's always one instance available? If you said: "manage a redundant cluster of at least 2 instances with non-overlapping maintenance windows" Then you were correct! BONUS QUESTIONS: Q…

The answer to #4 is probably that the goal isn't to always have ice cream. The goal is to run a profitable business. Doubling the cost of the ice cream infrastructure to avoid a 25% downtime may not be a profitable venture -- especially if the downtime is scheduled to occur while the store is closed.

McDonalds is in the real estate business (letting buildings), fast food is just a side order.

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.

Don't make joke a subcategory of clickbait, hacker news. come on now

If your "joke" is structured to sound sincere and be misleading, it's clickbait.

If your joke is structured to sound sincere and be misleading it's called a joke... that's literally what a joke is
