No relation to Pepe, who is an awful representative of the bathracians.

I got my PhD a tad under a year ago, there were plenty of congratulatory posts already, no need to milk it further. But the way the timing worked out, I just had my graduation ritual. If you would like to see my erstwhile advisor Dana Scott hood me, here you go.

@NeckarValue You may want to get in touch with these folks:

does anyone know a source of the total value/capitalization of US stocks in 1900? (or however far back)?

@siddharthagar @wolfejosh Your view may be consistent with the mores in your homeland, but, in the U.S., disrespecting our flag per se is fully protected by the First Amendment to the Constitution -- and that's the way it should be.

These people should spend spend just one day in one of the countries USA + Israel defend democracy against. Just one.

Congrats to @Tesla_Optimus team on another stellar update! The video gives us a peek at their human data collection farm, which I believe is Optimus' biggest lead. What does it take to build such a pipeline? Optimus nailed all of the following:
1. Optimus hands are among the best 5-finger, dexterous robot hands in the world. It's got tactile sensing, 11 degrees of freedom (DOF) compared to many competitors with only 6-7 DOF, and robustness to withstand lots of object interactions without constant maintenance.
2. Teleoperation software: we can see that the human operators are wearing VR goggles and gloves. It is very non-trivial to set up the software to have first-person video streamed in and precise control streamed out, while maintaining extremely low latency. Humans are highly sensitive to even the smallest delay between their own motions and the robot's. Optimus has a fluid whole body controller that enacts the human poses in real-time.
3. Sizeable fleet: you need more than one robot to collect data in parallel, well-trained human contractors taking multiple shifts per day (preferably 24/7), and an on-call maintenance crew to make sure that the robots are always busy. That's a ton of operational complexity that academic research labs don't even think of.
4. Tasks & environments: it's equally important to figure out *what* to teleoperate. Currently, most such efforts are demo-driven: collect data on the tasks that you want to put into a social media video. But solving general-purpose robots requires us to think carefully about the distribution of tasks and environments. From 43"-51" in the video, we can see factory & household settings like moving batteries, handling laundry, sorting daily objects into shelves.
It's an open-ended research question: if you only have the budget to collect training data for 1,000 tasks, what would you pick to maximize skill transfer and generalization?
Closing thought: teleoperation is a necessary but insufficient condition to solve humanoid robotics. It fundamentally does not scale. More about this later.

I will just leave this here, since a comment is unnecessary.

@filippie509 As far as I can tell, FANUC's robots have demonstrated much more sophisticated capabilities for years.

@ShortSightedCap There are people who would say 3 cats is weird. 😉

I need to figure my life out and have a kid.
That’s been one piece of advice I’ve consistently gotten: just get started, the timing will never be perfect.
I’ve been placating my wife with cats. We are at 3 cats. We cannot get a 4th cat. 3 cats is ok, 4 is weird.

@wolfejosh Leaving the question of genocide aside, with an estimated 75% of Gaza's population of 2.3 million people now displaced, it's hard to dispute the fact that Israel is engaged in ethnic cleansing.

Q:
1) 3 US soldiers were killed by drone in Jordan by militias linked to Iran
2) in devastating defensive counterstrike 10x proportionality over 30 were killed/injured (including innocent civilians) by US bombing strikes against 85 sites
3) is US committing “GENOCIDE”? 🙄

@AmazonHelp That was the first thing I checked: There is NO ERROR with regard to the passport number.

@LIBORsquared @LIBORsquared We're sorry for the difficulties. Some items can't be shipped to certain locations without additional verifications. You can learn more here: amzn.to/3RPUC2D. Please check that you have entered your information exactly as written on your ID. -Beth

@AmazonHelp I'm trying to purchase an item, but the checkout requires age verification. I've entered a valid passport #, but the order will not go through.
I've spoken to multiple Amazon reps during two phone calls totaling nearly 80 min, with no progress made. HELP!

@Mrs_Meowmerz @bethhentges For linear algebra, specifically, this is a nice resource from Gilbert Strang, whose 'Introduction to Linear Algebra' is a much loved classic:

Prepping for next semester (I will take differential equations and linear algebra), @bethhentges suggests I review anti-derivatives, integration by parts, and u-substitution. Thank goodness I still have the book! Does anyone else have other ideas? #math #futuremathematician

@ZekeFaux @PatrickEBoyle Just a couple of hours ago -- in the privacy of my bathroom -- I did some mining of my own, adding to the production of another asset "that is more scarce than gold".

this is such a good piece from @akilazoe on the French government's love affair with Binance

@gro_tsen Alors qu'il devait démarrer un 3ème cycle en génie chimique au MIT, Grace Jones remarque Dolph L. dans une boîte de nuit à Sydney. Il devient son garde du corps, puis son amant.
Grace Jones était une figure de la nuit new yorkaise et une icône gay -- le tour est joué...

Je suis désolé, je n'arrive pas à ne pas faire attention à Dolph Lundgren, là. 😳
Je veux tout savoir sur cette photo, mais je suis plus intéressé par l'aspect «où et quand est-ce que Dolph Lundgren s'habillait comme ça?» que «oh! un rhinocéros!».
Suave Morbida@Maitre_Poulard
Ne faites pas attention à Grace Jones et Dolph Lundgren, ce n'est pas le plus important sur la photo. La vraie question : c'est quoi cette oeuvre d'art chelou à droite, là?

@Jesse_Livermore Another grifter talking his book or a lunatic developing absurd economic theories around a financial monstrosity ($BTC).
Either way, it's not a good look.

Given that Gary Gensler's chairmanship of the S.E.C. has coincided with a #goldenageoffraud in the securities markets, it's hard to take him seriously in this area. Furthermore, what is the depth of his expertise in #ArtificialIntelligence?!?
