@smurthys @vitaut
I think that was written on the back of my toot.
So Please Turn Over.

My 60th done!

Have been trying for the last few weeks to break 21:00. Inevitably went off too fast, blew up, and slowed down. Was hoping to pace it better today.

Today was hot, but the legs felt good today and I made it!
20:48 🎉

Followed by a cooldown run with the gang and some 0% (flavoured) cold beers that I'd taken with me.

A good day so far :)

@sundogplanets in my BSc thesis I played this game for fun (Newton).
In "the real world" probably Landau1942 & Vlasov1927. They're not unrelated and they're kinda funny, Landau basically calls Vlasov an idiot in a hilarious manner.

@MCDuncanLab @sundogplanets
I came here to say this :)

Indeed, because it "looks" like the bread and the patty of a 🍔.

@abizern good luck with building up again! 🤞
Don't forget you can walk or run/walk at parkrun if that feels more approachable.

@astronomerritt I remember about 15 years ago someone talking about the same problems. They omitted their PhD from their CV when applying for "boring" nontechnical jobs, since otherwise EVERYONE assumed it was just a temp gig/job center thing and didn't want to hire them.

As you say, CV gaps are a bit risky, but there are definitely ways to square the circle.

@astronomerritt "2017-25: employed at university of X (various roles)"

Sufficiently vague while not being false?

@vitaut (except I think it's a trick question about the meaning of "home").

So... "Pollution"?

@vitaut I bet you plagiarized that question?

@RichiH the plastic and general waste blew me away.

Also the hotel changing sheets(?) and towels every day so I put the "please don't disturb/clean" sign on the door -- only to be surprised by a bag hanging on my door when I got back with clean linen.

Was a culture shock for me.

@hpcnotes non-serious answer:
I checked -- FP63 doesn't cut the mustard; FP65 is a waste of resources.

More serious answer:
I remember doing an exercise years ago where we plotted roundoff error, truncation error as a function of stepsize for a particular integrator. The window with FP32 wasn't so nice.

Even more serious answer:
I know people researching bounded errors -- not as accurate, but errors don't accumulate. There the "peace of mind" factor from using FP64 is probably less important.
