Summary: almost, but not quite entirely successful.
Launch successful. Booster separation and boost back burn looked good. Booster failed to relight some of its engines and hit the water hard. Successfully deployed the 20 starlink satellites. Successfully reignited an engine in flight to prove potential for de-orbit burn on future flight. Re-entry looked good and less spicy that some previous attempts (subjective). Such a soft landing that the ship flopped into the water without exploding and floated for a good long while (possibly still floating for all I know). Got some great drone footage flying over the heat-shield.
So the ship itself is looking increasingly good (so far) but they still seem to be having some issues with the booster.
I'm not sure I understand why even a truly obscure programming language article should ever be deleted; it's not like Wikipedia is running low on paper. If Odin ceased all development tomorrow it would be good to have some record of what it was.
For the record, I like Odin.
(On homebrew it appears to have been downloaded 6,707 in the past year. Compare to:)
Ha! This set it designed to take 114 years to construct and for maximum verisimilitude, Lego will run over your foot with a Lego tram after only a few decades of trying to build it.
Reminds me of one of the more brilliant passages in Snow Crash, describing work in "Fed Land"...

Y.T's mom pulls up the new memo, checks the time, and starts reading it. The estimated reading time is 15.62 minutes. Later, when Marietta does her end-of-day statistical roundup, sitting in her private office at 9:00 P.M., she will see the name of each employee and next to it, the amount of time spent reading this memo, and her reaction, based on the time spent, will go something like this:
Less than 10 min. Time for an employee conference and possible attitude counseling.
10-14 min. Keep an eye on this employee; may be developing slipshod attitude.
14-15.61 min. Employee is an efficient worker, may sometimes miss important details.
Exactly 15.62 min. Smartass. Needs attitude counseling.
15.63-16 min. Asswipe. Not to be trusted.
16-18 min. Employee is a methodical worker, may sometimes get hung up on minor details.
More than 18 min. Check the security videotape, see just what this employee was up to (e.g., possible unauthorized restroom break).
Y.T.'s mom decides to spend between fourteen and fifteen minutes reading the memo. It's better for younger workers to spend too long, to show that they're careful, not cocky. It's better for older workers to go a little fast, to show good management potential. She's pushing forty. She scans through the memo, hitting the Page Down button at reasonably regular intervals, occasionally paging back up to pretend to reread some earlier section. The computer is going to notice all this. It approves of rereading. It's a small thing, but over a decade or so this stuff really shows up on your work-habits summary.
Pluto is great. I use it all the time. If you like the reactivity/reproducibility but are wedded to Python, you might want to check out Marimo, which is also great. [https://marimo.io/]
It too puts the output of a cell above the code so if you're unable to adapt to things that are different it's also probably not for you.
FWIW, Observable's Notebooks (Javascript) work the same way: output above the code that produces it. [https://observablehq.com/]
I too did not like having the output above the code but got over it pretty quickly. For plots, it's arguably better: usually, I want to see the plot before I see the 15 line invocation of some plot command. The thing that bugs me the most about Pluto now is that it really wants you to only have a single evaluating statement per cell. You have to wrap stuff in "block......end" if you want to e.g. define more than one variable in a cell.
The headline is perhaps overstating things a bit but they do discuss how this is different than e.g. rivulets

This technology is fundamentally different from the “rivulet (shark skin) process,” which is known as a typical aerodynamic drag reduction technology. The rivulet process mimics the fine longitudinal grooves in shark skin, and by carving grooves approximately 0.1 mm wide along the direction of airflow, it aligns the vortices that occur near the wall surface of turbulent airflow areas. DMR, on the other hand, delays the switch from laminar to turbulent flow by means of random and minute irregularities. The flow zones it affects and the mechanisms it employs are based on completely different concepts.

I wonder what's holding them back from attempting to land...on land (as opposed to another splashdown in the ocean). They must have their reasons but there have got to be engineers dying to get their hands on a returned vehicle to see exactly how the tiles held up and if there's any other damage that doesn't show up so easily on the video feed.
Allen Downey (author of the above) has a number of books on computer science-y things. You can buy hardcopies but I think all of them are also just freely available.
"The plug on this device represents the latest thinking of the electrical industry's Plug Mutation Group, which, in a continuing effort to prevent consumers from causing hazardous electrical current to flow through their appliances, developed the Three-Pronged Plug, then the Plug Where One Prong is Bigger Than the Other. Your device is equiped with the revolutionary new Plug Whose Prongs Consist of Six Small Religious Figurines Made of Chocolate. DO NOT TRY TO PLUG IT IN! Lay it gently on the floor near an outlet, but out of direct sunlight, and clean it weekly with a damp handkerchief."
Sadly, the article says nothing about how old the fragment is or how it compares to other early copies of the Iliad. Somewhat amazingly, the earliest complete copy of the Iliad is from around 950 C.E.
Intro code snippet has two buttons ("+" and "-") in an HStack. Expected them to be arranged horizontally but in the accompanying screenshot they're stacked vertically. Is that intentional?
The failure of the upper stage is a bummer. If it triggers a months-long review, that will almost certainly bump back the schedule for the prototype Blue Moon lander launch.
