My #1 graduated this year. She crushed a 22yr old school record. She crushed dancing the jigs & reels of Irish dance for over a decade. She crushed the IB diploma. You didn't just want something - you decided. Go far, dear. Go far.

@The_Real_Fly How exactly does the rate affect CPI? Milton Friedman would like a word...

@MikeBales >5x daily.

It's therapeutic to vent your spleen, then delete all those bad vibes into the infinite darkness of the ether.

It's like erasing the chalkboard after a derivation goes awry.

@nikodavor @StevenGlinert Maybe a trial of sorts, let's call it a test, to see if they have the pre reqs...

@carl_feynman Was just commuting in DC/NoVA to the @Freakonomics broadcast about your father. The episode ended with the Orange Juice bongo song - and this pic shows up in my feed.

It hits hard when one understands there are real families and people in every story.

Thanks!

@johnkonrad Around age 40, every man chooses "his war".

My father chose the US Civil War. It looks like you picked The Great War, which has many lessons for our times.

@drgurner @PSaezT No. Social convention dictates that most women shave their beards before stepping back out into public.

From Theory to Image: The Evolution of Our View of Black Holes

The first ideas about gravitational objects so dense that even light cannot escape them arose as early as the 18th century. However, the true scientific foundation was laid in the 20th century with the work of Einstein. For a long time, black holes remained purely theoretical objects, mathematical wonders.

Forty years after the first serious sketches in 1978, in 2019, humanity finally saw a direct visual "portrait" of the shadow of a black hole (M87*).

@kenbensinger I'm not saying anything at all. That was engineered to reveal biases.

Try reading it as the other side. If you can't see it, you have been brainwashed and have temporarily lost critical thinking skills. (This goes for anyone reading this.)

Thank you for playing.

@ID_AA_Carmack most ppl consume 100 tweets about AI per day but zero papers. carmack reads 15 papers and writes code from 6 of them. thats why theres one carmack and a million commentators

The comment reminded me of my friend John.

One of my two best friends in college (not named "FutureDrWife") was a star offensive lineman on his HS football team. He was my height, but two of me: 6'4" 320lbs.

And 320# was probably the lowpoint for the rest of his life. He may have gone 550# before that tender soul passed. RIP JMM III, dear friend.

When my two friends and FutureDrWife shared summer housing at our Alma Mater, he kept setting the thermostat <60°F, because he was a hot sweaty mass of an immovable human otherwise.

I mean, really: put him in a three-point-stance and try to move him. It was fruitless, and he laughed a hearty belly laugh like St. Nick, and we all had a good time. College kids do stupid things,.

JMM III was a good Chemical Engineer from one of the best ChemE programs in the USA. He got his PhD in Organic. All my groomsmen got a PhD, or at least the lesser MD.

Our expensive bio, chem, biochem, physics, math, & engineering textbooks (and even those from the stupid-side of campus, like lit, econ, philosophy, & edu) could not stand the condensation from the <60 temps.

The books bent like cedar shakes in an Oregon fall. It took 5 years before my treasured Halliday/Resnik, Sears/Zemansky/Young, or Feynman Lectures on Physics laid flat on my desk.

@PunkyCovfefe That's a lovely picture of the punky couple. Frame it, and put it in the new house.

It's even better if your names match your halo: Adam and Marjorie, or something.

[Bob Hartley @RR_Hartley]

This guy is pretty good, as well.

[John Carmack @ID_AA_Carmack]

I admire Fabrice Bellard. He is almost certainly a better overall programmer than I am.

@Andypublicuk I love a story with a happy ending.

[Bob Hartley @RR_Hartley]

@BrianRoemmele That's so dystopian, I may not sleep tonight. ewww.

@DamonZumbroegel I think we could say that humanity has been mostly nuts for a long time.

Awesome pic, dude.

@skdh @StalwartSt I use humor to reinforce when I teach/instruct, and it's hard to cue the younger audience and still entertain (our) peers.

Usually, I go for the sophisticated, better humor and depend on the younger people to recognize the cues from the older people laughing.

[Bob Hartley @RR_Hartley]

@skdh @StalwartSt They get slapstick -- Three Stooges pratfalls, pie-in-the-face, falling down.

They do not get irony, sarcasm, or sophisticated jokes with callbacks from 10 minutes ago...

They look at peers, and if peers laugh, then they laugh as well - as a social response to fit in.

@davepl1968 I was just thinking that I listened to a fascinating podcast about the many ways that malloc can screw up and what it actually does in the OS.

Was going to quote post it. Couldn't find it ... Then I realized, it was you, right?

That was awesome. Thanks. Enjoyed it immensely.
