  • Fake or outdated info, actually.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 What I have found, unsurprisingly, is that methods and theories can get outdated quick.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    For the topic at hand, it doesn’t take much misinformation (or outdated information) to morph into something absolutely fake, or at best, completely wrong.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 am curious as to why they would offload any AI tasks to another chip? I just did a super quick search for upscaling models on GitHub (https://github.com/marcan/cl-waifu2x/tree/master/models) and they are tiny as far as AI models go.

    Its the rendering bit that takes all the complex maths, and if that is reduced, that would leave plenty of room for running a baby AI. Granted, the method I linked to was only doing 29k pixels per second, but they said they weren’t GPU optimized. (FSR4 is going to be fully GPU optimized, I am sure of it.)

    If the rendered image is only 85% of a 4k image, that’s ~1.2 million pixels that need to be computed and it still seems plausible to keep everything on the GPU.

    With all of that blurted out, is FSR4 AI going to be offloaded to something else? It seems like there would be a significant technical challenges in creating another data bus that would also have to sync with memory and the GPU for offloading AI compute at speeds that didn’t risk create additional lag. (I am just hypothesizing, btw.)


  • 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.




  • I was hoping that my heartburn would go away after I quit drinking a couple of years ago, but instead, it got worse. Honestly, that it’s probably because I started to form an actual diet and my stomach didn’t know what the fuck to do.

    Sigh. I am hoping this current mega-cycle of proton-pump inhibitors helps. It’s been a fairly high dose for about quadruple the normal length of time, so it might actually stick this time.




  • Kale has a naturally high pH, so it’s basically just an antacid. If it works consistently for you, keep it up. No point in taking industrial strength meds for something simple, after all.

    The class of drugs for my kind of heartburn are proton-pump inhibitors and help limit acid production across the board. It’s good these are over the counter now as I am on a 2x dose, but have been as high as 4x before.

    I switched from standard antacids to just water and baking soda my stomach was so bad. Kale wouldn’t have put a dent in my stomach acid, TBH. I drink a ton of water these days, and even if the pH of the water was off by a hair, it would be a bad time.

    I probably might be able to cut my dosage back or even stop soon hopefully. It’s one of the few drugs that are actually supposed to provide a long term solution.






  • With good directional antennas, the correct frequencies and analog signals and maybe last-mile AI/image recognition, 30-50 miles should be easy. You could even use a high altitude drone as a signal repeater for even more range with minimal latency.

    For perspective: I could communicate with ham radio repeaters using a 5W transmitter and a basic whip antenna at about 150 miles, at 220/440mhz, because the repeater was in a high enough spot, on a distant mountain. Granted, that was only voice but it’s still a good representation of what kind of range you can get.

    Digital signals at higher frequencies wouldn’t have much of a chance.

    Edit: We are entering a period of high solar activity as well. While atmospheric bounce is usually reserved for other bands (usually 10m, or ~29mhz) it can absolutely be a thing with higher frequencies now.
