  • (thinks out lound…)

    If you could force different speeds and different voltages, you can make some guesses as to what the cable might support.

    USB packets use CRC checks, so a bad checksum may indicate a speed or physical problem. (Besides stating the obvious, my point is that doing strict checks for each USB mode gives CRC more value.)

    I just looked over the source code for libusb (like I knew what I was looking for, or something) and it seems that some of the driver(?) components hook really deep into the kernel. There might be a way to test specific parts of any type of handshake (for dataflow or voltage negotiation) to isolate specific wires that are bad by the process of elimination.

    I think my point is that a top-down approach is likely possible, but it’s probabilistic.







  • Fake or outdated info, actually.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 What I have found, unsurprisingly, is that methods and theories can get outdated quick.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    For the topic at hand, it doesn’t take much misinformation (or outdated information) to morph into something absolutely fake, or at best, completely wrong.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.




  • That is probably some good theory crafting, but I have no idea as that is a level of psychology that is beyond me. (That sentence looks a little smart-ass, but it absolutely isn’t, btw. 100% curious.)

    Personally, I can say is that I tend avoid foods that cause pain and may even subconsciously steer away from them too. I don’t actively seek out things like tomato sauce, but wouldn’t likely turn down a free spaghetti meal either.

    I do also tend to prefer cereal and milk, generally heavy fiber types. Antacids are great, but sometimes, just giving my stomach something harder to break down works fine too.


  • Just stay away from nearly anything that uses “healing ions” in its marketing material. If it’s not a straight-up fake product, it’ll likely kill you in due time. (Ozone generators are an exception unless you get a beefy one like mine, and then it can actually kill you.)

    Edit: lol! I have seen that video and made my comment about ions before I clicked it. Good video, btw. 5 stars.


  • For anyone else reading, baking soda can save you hundreds of dollars on regular antacids. One you get past the taste and train your body it brings relief, it’ll be tasting like champagne soon enough.

    LPT: Baking soda and water can burn your mouth and lips after a time as well, so keep it fairly dilute. More is sometimes needed, but not always better.

    Second LPT: Get a second small box of baking soda for heartburn use and keep it sealed in a Ziploc or something. It will absorb all kinds of stuff out of the air and end up tasting really bad. (Name-brand baking sodas tend to taste a little less fishy as well, but not by much.)

    Sorry, I know more about baking soda now than I care to admit. It’s really a super interesting chemical, even in its simplicity.
