  • I’m sure that there are examples of actually wasted money, but just putting it out there that planning is fucking important. There have been several high profile projects, like Texas high speed rail, where planning was the hard part and the project got canceled as they were ready to break ground because “there was no progress”. Cue* Republicans “the government does nothing” after they stopped anything from happening. Infrastructure cannot operate on election cycle timelines.

    Digging in the ground and integrating with existing infrastructure isn’t just a plug and play operation. Leases and liens need to be sorted out. Estimates of current and future demand needs to be sorted out so you don’t install useless networks. Fiber isn’t that heavy, but “can the existing conduits under bridges/roads/etc support it and/or do they have room to without a complete replacement” isn’t a trivial question for backbone lines.

    Winging it just causes more problems as you find things you didn’t anticipate and cause delays while having to continue paying contracts so work can resume once the delay is cleared. If you don’t, the contractor is on to their next job and unavailable for an effectively random amount of time. While everyone is mad at you that “no work is being done”.

    It could be done faster, but it would cost more. Because planning is really important to keep multi-million/billion dollar projects accountable and on track.



  • I feel like using that statistic is misleading in terms of efficiency just from the factor of “gallons of gas per pound of food transported”.

    Sure there’s spoilage from product going bad, but marginal efficiency gains there are so far down the list of things to worry about that they’re not really worth going into. The reason people don’t have food isn’t because enough isn’t produced, it’s because they’re not allowed to have it because they don’t have enough money. Less food spoiling doesn’t fix that problem.







  • “Computer” meaning a mechanical/electro-mechanical/electrical machine wasn’t used until around after WWII.

    Babbag’s difference/analytical engines weren’t confusing because people called them a computer, they didn’t.

    “On two occasions I have been asked, ‘Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?’ I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.”

    • Charles Babbage

    If you give any computer, human or machine, random numbers, it will not give you “correct answers”.

    It’s possible Babbage lacked the social skills to detect sarcasm. We also have several high profile cases of people just trusting LLMs to file legal briefs and official government ‘studies’ because the LLM “said it was real”.





  • That’s what config files are for. It would be a nightmare to hardcode weight and balance and have to recompile the HUD every time you change the loadout or refuel the plane.

    Most code, algorithms, etc are not any more sensitive than the concept of desks and file cabinets. No, guidance programs for missiles probably shouldn’t be put on GitHub, but there’s a reason RSA and other encryption algorithms were open sourced. It’s better to have more eyes looking for inefficiencies, weaknesses, and vulnerabilities than to just assume it’s good because no-one on the team responsible is smart/engaged enough to find them.








  • Why?

    Every vehicle doesn’t need to do everything. Otherwise we’d all buy turbocharged Hummers with a trailer for extra fuel. It’d be nice to have some middle ground between a smartcar that confined to surface streets and something you’d take a roadtrip in. A worst-case ~150-200 mile range is enough for a boatload of people to commute 50 miles and not have to worry. If you can plug it in overnight, even on just 120v, charging speed is a negligible concern.

    I think a lot of range anxiety is weird. A lot of gas cars from the 80s/90s/00s have ~300/400 mile range per tank, but that’s because you don’t want to go to a gas station every day. If you could just trickle in gas overnight they could’ve had much smaller tanks too.
