OT - What are you doing right now?

JohnInCarolina

Prepping for an entire day of back to back to back Zoom meetings.

picked the first of the san marzano tomatoes off the vine this morning. new type to me san marzano  redorta, big as a beer can and as sweet as any heirlooms ive ever tasted. hope they have these next year much better than the regular san marzanos ive grown in the past

fishlessman

School starts tomorrow.  Duck is SWMBO, Jr’s favorite, so I’m cooking duck tonight.

Just because this, while cooked on a gas side burner, is awesome!

Thinking about dropping this in their mailbox today as well...that exclamation point 😡

I've dropped a few of those back into the mail box before. Today, again, I walked the mail intended for the widow next door, from my mailbox to hers. I also live 3 houses from an inter section. To the right three houses from the intersection is another house with the same street number. I've lost count of the mail that I have walked over to their door. Mail trucks need a gps with a moving map display if they can't tell which street they are on.

Trying to come up with a relatively simple real-world example that gives rise to a nonlinear system of equations, for my class.

I'm spitballing here. What about for a certain conical cross section of a wine/champagne glass, how tall would it need to be to hold x ounces of wine?
That the kind of thing we're talking about?

fishlessman

how much gin did i drink from my parabolic mug. first glass was full, second glass was 2/3rds full, third glass was half full. thats the best i got if i understand this right but really have no clue my liver doctor needs to know. make it tricky, first glass has a quarter of a lime, secong glass has two, third glass has three...to keep count

too funny, we both had the same twisted drinking idea

This will morf into a Krzyzewskiville drinking game named after JIC.

@fiahlessman grew up in upstate NY and loved those split-tail hot dog buns.  A bit harder to find (the buns ) in these parts.  Great looking dogs right there!

was stumped on how to make a hot dog out in montana back 30 or so years ago with potato buns, i didnt buy buns. the other horrifying encounter was all the orange cheese, i was sent off to get a weeks worth of cheese for the group  and came back saying there is no cheese. we didnt buy cheese for the week either.

Look John, were not all making Duke professor money, so I’m sure some people are going to be hesitant to help you out without some kind of, um, consideration.

How about figuring the cook time for a hunk of protein?  You’ve got cook temp, IT, weight of protein.  Stall.  For the advanced kids, maybe toss a 22 hour 4lb pork butt at them, or a brisket cooked mostly on a smoker and finished in an instant pot.

They are probably all vegans. But maybe they can figure out how many licks it takes to get to the center of a tootsie pop.

What's funny is the assumption I was looking for help.  I was just telling you guys what I was doing.  

For those interested - the problem I have settled on is a discrete version of the catenary problem.  Imagine you have a string tied at both ends with a set of weights hanging on it at different locations.  The problem is to find the final location of the weights.

It was a fun distraction anyway. We made an assumption that you were brainstorming. You know what they say about assumptions...

Awwww...the catenary problem. Too easy.

Oh.  I thought you said real world problem.

Is that similar to discrete rectal problems?

I build subsea SCR’s (steel catenary risers) for a living. Does that mean I am smart too?

Legume said:

It can be described as one.  You want to run a zip line across your back yard between two trees.  If you know the weight of the cable, what kind of tension do you need to put into it to prevent it from drooping too low somewhere in the middle?

Maybe.  I suppose the answer depends upon whether or not you've figured out a way to work anus into the designs...

alaskanassasin

nope but it does mean you lay really large pipe in giant holes.

That's easy, Tie one end to a tree and the other end to your tractor. Then pull.

Inverted pendulum or anything with real world damping is pretty much non-linear.
