<p>Data point:  A couple years ago I worked for a company that calculated sales tax for customers.  They had developed expertise in knowing where each jurisdiction kept it's tax code and how to turn that tax code into software.  I was peripherally involved in a proof-of-concept where a reasonably well skilled team trained some sort of model on tax code for one US state.  They demoed it to the board of directors where one of the directors asked a somewhat complex question.<p>The model returned an answer that looked legit, but after the board meeting someone pointed out that the answer was wrong and had we given this answer to a paying customer, we might have been criminally liable.  I'm not sure <i>who</i> would have been criminally liable.  I don't think they would arrest the entire company.<p>This was over two years ago and Claude seems to be getting MUCH better over the last year, so maybe things are better now.  But, as the Russians say, "доверяй, но проверяй" (trust, but verify.)</p>

<p>but the metric the OP was using was power density.  nuke fuels are MUCH more energy dense than hydrocarbon fuels.  but putting a reactor on each plane would probably have negative externalities.<p>but mixing your comment with a few others, maybe a nuke plant on the ground that cracks the co2 in the atmosphere to make carbon neutral hydrocarbon fuel.</p>

<p>i wish there was more talk about this.  it seems i heard a lot about making hydrocarbons from co2 in the air + solar or algae a couple years ago.  if your hydrocarbons are made this way it seems they would be carbon neutral.<p>i'm guessing there's more research to make it feasable since i haven't seen "carbon neutral gas alternative" at the local Chevron.</p>

<p>i would have given this guy credit if he compared cost of production for petro fuels when talking about energy debt.<p>also conflates power with energy, but fine.<p>if you talk about cost (dollar or kilowatt hour) per joule delivered to a vehicle and then compared the total cost of electric vs. the total cost of petro, i would listen.  but he ignored the fact that petro fuels cost money, energy and water to produce.<p>and there some things electric motors can do that ice can't.  an electric ekranoplan isn't too infeasible, but we know from soviet studies you can't keep salt water out of an aspirated motor when you're that close to the water's surface.  turns out electric motors can be sealed against water.<p>and dissing physicists?  wtf?  makes me think he failed out of an engineering physics degree cause he didn't understand math.  as we used to say, the limit of a bs or be as gpa approaches zero is bba.</p>

<p>Back in the day Convex Computer Corporation was laying off a large fraction of its staff.<p>The plan was to come into the warroom and just hang out.  Your manager would come and get you and take you into a private conference room to discuss your package with an HR specialist.  The packages were pretty decent, at least.<p>In gallows humor I drew some stick figures on a white board for each of my team with their unix logins below them.  As people were RIFfed, I would go over and put a universal red circle and slash "no" symbol around the figures who were laid off.<p>My time came and I marked myself as a "no" and handed the red marker to a co-worker.<p>I remember being a little ticked off at my manager, but when I came back to say goodbye to everyone I noticed his figure / login name had been exed out.  The last thing he did before metaphorically being shot in the head was to metaphorically strangle half his children.<p>"What was deluxe became debris, I never questioned loyalty.  But this dead end demolishes the dream of an open highway."</p>

<p>Modern CS programs teach to what they perceive to be the interview their students will encounter after graduation: what is a tree data structure, how to craft a SQL query and how to calculate a CRC with a python library.  More advanced CS/CE departments still teach discrete math and compilers/parsing for students intending to go to grad schools.<p>My experience with recent CS grads is it's easier to hire Art and Political Science grads and take the time to teach them programming and all it's fundamentals.  At least they won't argue with you when you tell them not to use regexes to parse HTML.</p>

<p>we lived in rona hills for about 4 years.  not biking distance, but close enough to visit frequently.  and as a youngster they let me conduct the AF orchestra there at the AF 25th anniversary.  Very good memories.</p>

<p>Apropos of Don't Look Up, 2024 YR4 doesn't yet have an official name (or at least I haven't heard it if it does.)  So my friends have started calling it "2024 Dibiasky" as a joke.</p>

<p>I was sort of pulling for the asteroid and got depressed when I heard this, but then realized...  0.28 percent is not zero.  There's still enough of a chance it'll hit that we're going to be forced to take it seriously.<p>In the states we're dismantiling our research and development infrastructure (will the last person at Stennis or JPL please turn out the lights) but China has been making strides and the ESA has a pretty decent record of launching things, so maybe there's enough time for them to plan, launch and execute a DART-like impact mission on 2024 YR4.<p>We will know we're living in a simulation if North Korea puts a nuke on a large rocket and successfully deflects it.</p>

<p>I guess this is for DOS only systems?  I used elm on BSD/386 in the 80s, and honestly was a little surprised to learn it's still being maintained by Kari Hurtta.  And then I was thinking, Pegasus can't be older than Pine, Alpine or Mutt, can it?  But yes, it is.  You learn something new every day.</p>
