  • Fake or outdated info, actually. While this is a small tangent, I make it a habit to review basic, introductory information on a regular basis. (For example, I’ll still watch the occasional 3D printer 101 guide even though I could probably build one from scratch while blindfolded.)

    I have been in IT for a very long time and have branched out into other engineering fields over the years. What I have found, unsurprisingly, is that methods and theories can get outdated quick. So, regularly reviewing things I consider “engineering gospel” is just healthy practice.

    For the topic at hand, it doesn’t take much misinformation (or outdated information) to morph into something absolutely fake, or at best, completely wrong. It takes work to separate fact from fiction and many people are too lazy to look past internet pictures with words, or 15 second video clips. (It’s also hard to break out of believing unverified information “just because that’s the way is”.)




  • I suppose you are correct. If the bit isn’t structural, it doesn’t need to pass any test for microcracks. If it is structural and it passes testing, YOLO that shit.

    It’s just the core frames that need serious attention though. I don’t think I have been around a single aircraft that wasn’t constantly bleeding some kind of fluid, so everything else not related to getting the thing in the air and keeping it from completely disintegrating while in flight is mostly optional. (I am joking, but not really. Airplanes hold the weird dichotomy of being strangely robust and extremely fragile at the same time.)


  • And there are significant technology differences. The new upgrade will be the B-52J or K.

    Proper aircraft maintenance cycles are intense, so it would surprise me if any of airframes we use now have 1952 original parts. Aircraft are subject to lots of vibration and the aluminum in B-52s will eventually stress-crack because of it. (It wouldn’t surprise me if composites were added in many places instead of aluminum replacements, but that is just speculation.)

    Also during those maintenance cycles, it’s much easier to do systems upgrades since the aircraft is basically torn down to its frame anyway.

    It’s the same design to what we had in 1952, but they ain’t the same aircraft, philosophically speaking.









  • The proper metric to plan around is longevity, unless you absolutely need performance now.

    Performance and cost should be divided by time. Do you think that bit of hardware will be able to support software for the next two years, or five? That is one way to “compute” value, anyway.

    A 4090 will eventually be outdated and unable to run new software, but that may not happen for a good number of years. If you want to get super deep, start crunching the numbers on power costs too. It may simply become too inefficient to run, eventually. (Hell, it’s probably super inefficient now, actually.)

    I almost always buy top-tier “last-gen” tech, right after “new-gen” is released when I am saving money. When I have the extra cash and it makes sense, top-tier may also be a good investment.

    Be honest with yourself and determine what matters most to you and put your money there.
