  • Blowing up rockets gets people really upset when they think it’s their tax dollars.

    I love spaceflight and what the Artemis II accomplished, but it came with an absolutely staggering price tag. It cost a bit more than $50 Billion to design including both the rocket and the Orion capsule. It costs $1Billion each time it launches too. We only bought enough parts for 4 flights of the rocket, and we’ve now used 2 of those.


  • artemis (boeing)

    Just for the clarity of the record:

    • the 1st stage tank of the SLS rocket is Boeing
    • the 2nd stage is ULA (a joint Boeing/Lockheed company)
    • the 1st and 2nd stage engines are Aerojet Rockdyne (which is now a subsidiary of L3Harris Technologies)
    • the solid rocket boosters on the side are Northrop Grumman
    • the service module is Airbus Defense and Space along with Thales
    • the capsule is Lockheed

    So you’ve got four giant American defense contractors, and two European defense contractors owned by French, German, Spain, and Italy.

    Maybe the communal part is the community of western defense contractors.






  • They are shitting out what you feed them. If you feed them garbage, you get garbage in return.

    This is the missing conceptual understanding that probably 90% of LLM users lack. They really don’t know how LLMs work, and treat them like AGI. Sadly this includes adult policy makers in our society too. Efforts like those of these these researchers act to educate the public. I’m hopeful this will spark some critical thinking on the part of regular, otherwise ignorant, LLM users.


  • That’s a serious breach of ethics and morals. Feeding false information to an LLM is no different that a magazine.

    Hang on. Are you suggesting its unethical/immoral to lie to a machine?

    Additionally, the authors didn’t submit the article to a magazine as factual. They posted the articles on a preprint server which can be very questionable anyway as there is no peer review. The machine chose to ignore rigor and treat them as fact.





  • It’s not a bad question, though. There are strategies to protect your portfolio from economic downturns.

    It could be a bad question (from the client). If they are invested for higher growth, that comes with risk. If they’re looking at the their portfolio, seeing a 3% drop in value, and then asking for change it tells me they don’t have the right risk tolerance for the investments they have. This may mean either the broker didn’t listen to the client when the client told them their risk tolerance, or the client lied with how much risk tolerance they had.


  • Under changes in the tax law, private jet buyers can deduct the full cost of the aircraft from their taxes in the year it is purchased if it is used at least half of the time for business.

    So if you buy the jet in December and take a single business trip (and no personal trips), you would have 100% of the jet flights for business in the year you purchased the jet? It looks like you would then get a tax deductible jet for whatever use you want going forward?

    “We, along with the whole industry, definitely saw a pretty significant uptick in demand in the back half last year, which we’re attributing to the 100% bonus depreciation,” Shevlin said. “We expect the same thing to happen at the end of this year.”

    This looks like it confirms my suspicion.
