@TheStingisBack Without resupply with munitions, etc., how long could a 1980s carrier be effective in the 1940s?

@TheStingisBack You’d splash the Zeroes. Everyone who has ever watched the movie would splash the Zeroes. The entire movie is based around that one moment of splashing the Zeroes.

@MATLAB This doesn't accurately simulate Artemis II at all -- it doesn't have the initial high Earth orbit.

I don't think that anyone is surprised by this, just that it took so long to surface. The authors themselves said there were many such operations. Who wants to put money on this being in Euler's papers somewhere? Maybe a better version?

Polski naukowiec napisał ciekawą pracę - i nie bójmy się nazwać jej przełomową. Przez setki lat matematyka miała dziesiątki “podstawowych” funkcji jak sinus, cosinus, logarytm, pierwiastek, eksponenta. Znacie to ze szkoły. Wiadomo o co chodzi. Fizyk z Uniwersytetu Jagiellońskiego właśnie pokazał, że to wszystko jeden operator: E(x, y) = exp(x) - ln(y), oraz 1. Sin, cos, π - wszystko z tego pięknie wynika, wystarczy odpowiednio zagnieździć. Natura ukryła najprostszy możliwy zapis rzeczywistości. I znaleźliśmy go przez przypadek. Całość jest piękna i wspaniała, a słowo „przełomowe” nie stanowi tu marketingowego buzzworda. Przykładowo zamiast pisać π czy 3.14 można teraz elegancko E(E(E(1,E(E(1,E(1,E(E(1,E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(E(E(E(E(1,E(E(1,E(1,E(E(1,E(E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(E(1,E(E(1,E(E(1,E(E(1,1),1)),E(E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(1,1)),1))),1)),1)),1)),1))),1)),E(E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(E(1,E(E(1,E(1,E(E(1,E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(1,1))),1))),1)),1)),1)),1),1),1))),1))),1)),E(E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(E(1,E(E(1,E(1,E(E(1,E(E(1,E(E(1,E(1,E(E(1,1),1))),1)),E(1,1))),1))),1)),1)),1)),1)

I use YMD in coding because it sorts. BUT, let me speak out for MDY. YMD is most-significant first. But I argue that the *month* is most significant. Today it's the 13th. Should you wear a jacket today? Today it's 2026. Should you plant crops today? Today it's April. Should you be ready for sakura season? Month carries the most information.

I am hesitant to get ahead of a proper data review, but I understand the space community’s curiosity, especially when imagery can give the impression of a problem. As you would expect, engineers were eager to inspect the heat shield, starting with diver imagery shortly after splashdown and continuing with the review aboard the ship. No unexpected conditions were observed. I suspect when the images are released, it will be pretty obvious the stark difference between Artemis I and Artemis II head shield performance. As to the question specifically, the discoloration was not liberated material. The white color observed corresponds to the compression pad area and is consistent with the local geometry, AVCOAT byproducts, and transitional heating environments. We observed this behavior in arc jet testing and expected it in this compression pad area. We will complete a full data review across all systems, including the thermal protection system, and make the results publicly available.

The Canadian astronaut on artemis 2 had to clear customs to enter the US, but only before the flight. Florida to the Moon to California is a domestic flight🇺🇲

@kwan3217 @straceX And if you know you are doing something like that you can use fno-delete-null-pointer-checks which will disable this kind of optimization.

This function has a NULL check. GCC at -O2 can remove it. not a bug the C standard allows it. under optimization, that if-check may not survive to the binary.

@straceX int type=r->type; already causes segfault if the r is null, so "if" after it is irrelevant. Put it before and the compiler won't skip it.

@NASAArtemis now that you are down safe we can complain and demand transparency on the heat shield. Buy a Falcon heavy, put a production model heat shield on Integrity, and re fly EFT1.

New hire orientation today. HR introduces me as "the person who makes sure your computers work." Absolutely not. I correct her: "I’m the person who makes sure your tickets are properly categorized so someone else might eventually make your computers work." I give my standard onboarding speech: Never email me directly. I will paste "Please open a ticket" and ignore the rest. If you DM me on Teams, I will create a ticket in your name and mark it "Awaiting User Info" before you finish typing. If you walk up to my desk without a ticket number, I will rotate my monitor 180 degrees, show you the portal, and watch you fill it out like an SAT proctor. They laugh. I don’t. HR thinks I’m joking. My team knows I just set my Q2 SLA shield to 100%.
