It's become even more obviously a scam when it received the support of the scammer-in-chief. With his crypto being so obviously a nice pathway for bribery, credibility of any crypto gets questioned. Which is more harmful considering that it was never more than a betting market in the first place. At least with gold you've got a lump of stuff most people consider valuable, rather than hoping that some small set of people with money to burn buy more of the same stuff you did being the only value proposition.

You can send them a Postscript file generally, which is an image format.

Actually, Postscript is a programming language which is designed to draw text and vector graphic images for printers: so more analogous to today's gcode than an image format. I've even seen someone write postscript to do a linear regression fit on the plot being printed. Why? Because it was possible :)

Comment Re:starting college vs overall college: a distinct (Score 2) 57

Be careful this. Sure, stuff will transfer. But, that won't mean you get two years off your four year degree.

Why?

Because for most majors, there are specialized courses for that major that will happen during the first two years: often ones that are needed for upper level third and fourth year classes. Two year schools don't offer them. So, transfer students often spend their first year catching up on such courses (eg, sophomore level special relativity and quantum mechanics for a physics major), then they're set to dive into the upper level classes.

"How awful of you elitist university people!!!", you say.

But: should we hold off on offering non-general education classes to our own students, refusing to engage them with interesting classes needed to learn more advanced stuff? That would be malpractice to our existing students.

Under Biden US taxpayers were funding the Ukraine war effort virtually alone, the current administration has convinced Ukraine's neighbors to start buying the U.S. weapons Ukraine needs to fight Russia.

No - it was still majority European funding at that point: even in absolute terms, not counting for GDP to aid normalization (which really tilts the stats). Since then, the US has stopped and the EU has tried to ramp up to full the hole, true. But it was never a majority US operation.

It was also somewhat self-serving all along: less cash handed out to Ukraine, more cash to US factories to make the stuff to send over. Which is a reasonable way to do it (jobs for people in Alabama munitions factories AND artillery shells to shoot at Russians!), but somehow escapes the notice of critics.

Comment Re: What an ironic comment (Score 1) 199

My EV6 has a 77kwH battery, so 0->100% would be 462kW to charge in 10m (1/6 of an hour). Given that I can pull 230kW off a DC fast charger, can't do that in 10m but can in 20m. (To be fair, that's the peak of the charging curve, so I don't get that for all 20m. But I'm also usually charging from 20%->80%, so less than 20m is indeed the typical L1 charger stop length on a road trip: about the same time it takes to unload the bladder and go buy something to refill it with for the next several hours of the trip).

For what it's worth, segments of the govt mandate ipv6 usage. The Dept. of Energy has done so. Which actually causes problems for large installations of legacy and specialized equipment such as particle physics labs. Trying to get many many old embedded devices to talk ipv6 just because it would be nice to do so isn't worth doing when you're in your own non-routable address space anyway.

Comment Re:No evidence (Score 1) 89

The evidence is on my tests, when students who used AI (or Chegg or whatever) to not think at all about the homework or classwork through the semester hit an exam and can't do jack without their helper.

The student evaluations are then filled with indignation from those same people who whine about tests not covering the same thing as the homework. When in fact many homework problems are recycled as test questions: but they abdicated the chance to learn by actually working to do so, in the process developing no skills, learning nothing, and not even recognizing the test questions as something they once pasted into a chatbot.

You could argue that this isn't testing "cognition". Fine. I'm not in the business of teaching cognition, I'm in the business of teaching problem solving skills to students, disguised as learning how Mother Nature runs the universe via the laws of physics.

Well, only if you want to call, for example, all the math classes and CS and chemistry etc "outside the major" for purposes of (in my case) a Physics Major. In your case, you probably don't want your EEs getting a degree without math, physics, and CS for example.

I think the real question here is "what fraction of a major is lib Ed stuff?". At my school, it's 30 out of 120 credits for everyone (EE included). To be fair, many majors require more than the minimum "120" credits anyway, decreasing this percentage. And many of those "30" are satisified with the required math/cs/physics/chem etc anyway. So in practice it's closer to 15% "random fluffy crap" than the 25% it appears to be on the face of it. And all the physics and EE majors I work with actually look forward to the random Jazz Studies class as a place they can coast for three credits while fighting with Digital Signal Processing or Quantum Mechanics in their day job.

I'd be really curious if you can dig up any (non-AI) videos of Clinton or Obama endorsing AfD or sieg-heiling at the inauguration? Certainly they didn't abolish the US's foreign aid program leaving millions of kids to die while letting the aid rot on pallets in warehouses, for example. Any one of those things (let alone the shambolic DOGE thing) would have poisoned any brand.

The mass distribution needed to explain spiral galaxies assumes that this "dark matter" remains at the periphery of the galaxy, keeping the rotational velocities constant as one moves away from the galactic center.

Umm... no?

If you're going to be convinced that people are making shit up, at least get things right about what they're making up: maybe sit down with Kepler's law, a pencil, and Gauss' law?

If you do so, you get the ad hoc model that matches observations in most galaxies pretty well. That's very not constant, and in fact very centrally peaked, because the radial velocity distributions are only constant in the outer reaches. It's the density distribution that provides the gravity to make the radial velocities do what they do.

One can also start with more similar dark and luminous matter distributions and run them forward in time to get this, so it's not just a magical solution, it's something you get from orbital dynamics over time. Details of galaxy formation are still fuzzy, but the end result that we see is perfectly plausible - mostly because dynamical friction increases rapidly as the density of stuff increases, so you lose more orbital energy inthe core and stuff clumps up more there.

ahh wait, I see. You're still thinking that somehow Dark Matter isn't in the solar system. It can be (and probably is), at the same density needed to mess with the rotation of the galaxy. However, (tiny density)x(tiny solar system volume)=not enough mass to show up in orbital dynamics. On the other hand, (same tiny density)x(galaxy sized volume) adds up to way more dark matter than "normal" matter in our galaxy.

Just because we don't know what the stuff is doesn't mean we don't see it doing stuff. And it's doing stuff that's consistent with a soup of stuff that interacts via gravity and not electromagnetism. That's the fun part of science! There's something going on we can see happening, now we get to figure out what's going on.
