I'm not going to bother to write an essay like the other person.

Here is a scientific outcome that directly impacts the quality of medicine a majority of American citizens receive: https://jamanetwork.com/journals/jamanetworkopen/fullarticle...

Research in progress to address these issues was cancelled by DOGE because "melanin content of the skin." "Do your own research" if you care to, or fuck off.

Great question! Mostly it goes toward maintaining the campus and paying the admin folks. PIs are paid to teach, basically, and are expected to pull in the money to support their own research (and maintain their facilities and pay the admin folks).

Aside from the occasional problems like printers waking up at night to print gibberish [0] and attempts at locking down their ecosystem [1], Bambu Lab makes the most consistent, reliable printers for casual use you will find.

How about if people with a higher reputation contribute an exponentially higher score when voting? Like, someone with ten top-rated answers has a 1,000-point vote (more nuanced than that, obviously).

As someone who is essentially financially illiterate, what does this mean, "allocate resources efficiently?" Nobody's investing in companies that promise to cure world hunger or alleviate childhood suffering. They're investing in technologies that can extract the most wealth from the population, regardless of externalities. Is that desirable?

Then again, I can't fathom what people would be doing with their money if the stock market weren't there. I imagine they might naturally wind up with some sort of...stock market.

Yes, it probably is. Have you ever heard of the spherical cow?*

Simplifying the surface makes it possible to model the system with equations that can be solved analytically--which gives theorists something to work on. Modeling more complex systems (which often happens, eventually) typically requires lots of computing power and results in a model that doesn't generalize well.

I hope you're not implying they're already digging mass graves. Some are unaccounted for--they're probably in Guatemala or something. Some will die. But I don't see the gas chambers being built for, like, another six months at least.

If you're talking about ICE, it's officially 15 so far this year. [0]

While this outbreak is bad for DR Congo, I wonder whether they will be able to contain it within their borders without adequate support.

Hmm...I wonder if it matters which browser is being used.

My US bank removed check deposits from the browser about a decade ago, and I haven't met anyone who can use Zelle without an app.

Makes one wonder what the world will look like in 50 or 100 years. Which sci-fi alien civilization will we most closely resemble?

Yes, I can see many similarities.

- Your code specifies design constraints--you need it to do X and Y and Z.

   - The engine designers needed the engine to fit in X and operate at Y temperature and not blow up (Z).

- The compiler takes your instructions and optimizes them for the processor instruction set.

   - This program optimizes the engine design for the physics instruction set.

It seems like both represent huge productivity leaps from laboriously making things in the original low-level languages.

I shortened the title a bit from "LEAP 71 hot-fires 3D-printed liquid-fuel rocket engine designed through Noyron Computational Model."

From the article:

- First rocket engine built entirely through a computational model without human intervention

- Likely the shortest time from spec to manufacturing for a new rocket engine (2 weeks, usually this process takes many months in manual engineering using CAD)

- First liquid fueled rocket engine developed in the United Arab Emirates

- Engine worked on the first attempt

- No CAD was used in the design

I sure hope you're keeping on top of all the Win7 telemetry updates, then.
