  • The earth is estimated to “weigh” 13,170,000,000,000,000,000,000,000 pounds. (That is weird when you think about it. The weight of the earth being based on what something weighs on earth, I mean.)

    Mt. Everest is only about 357,000,000,000,000 pounds and is just a tiny fraction of the mass of the earth.

    So. My point is that we need a better way to portray scale of things in the universe. AUs work to a point but then we have to quickly move to parsecs. Parsecs quickly give way to light years. (Or vice-versa, depending on how you visualize things better.) Light years kinda work, but only for between 14-26 billion years. Even after all of that, I can hardly still fathom the size of Mt. Everest. (This was a rant, but not an angry rant.)









  • It was totally fine. Borg implants or not, she was still human. She also didn’t have a choice about becoming Borg at such a young age. When her connection was cut with the collective, she basically became a child again making her Janeway’s responsibility. (That was close to Janeway’s logic I believe, and I agree with it. It was a human decision for another human who was incapable of making decisions.)

    The biggest thing is that Seven has already signed a contract with UPN, so she was kinda stuck for a few episodes anyway. Janeway knew this, so after thinking about it over a 50 gallon drum of coffee and a few packs of menthol Kools, she decided to just run with it and make it dramatic. (The Borg attorneys failed to overturn the terms of the contract even after several weeks of absolutely phenomenal work.)


  • There are about a million different flavors of how to download and execute a shell script. Regardless, you need to redirect the output of curl into bash with the -s flag. Bash needs to know that it is reading from STDIN.

    Here is an over-thought stackoverflow page on it: https://stackoverflow.com/questions/5735666/execute-bash-script-from-url

    Also, if the script is not being read properly, that might explain the dpkg lock issue. Running two instances of dpkg simultaneously is likely causing that collision you are seeing. (If one instance is running, it will touch a lock file and then delete it when it stops. It prevents “bad things” from happening when two instances of the same app want the same resources.)

    That is odd if your path is broken. It curl should be in /usr/bin and ‘which’ should find it. Are you somehow launching another shell inside a shell? Like zsh inside of bash, or something in that flavor? (In some rare cases, that would break paths and profile configs for your active shell.)

    Regardless of why curl isn’t being found, or only partially found, or something, learn “env”. You need to get a decent picture of what your working environment is and why something as basic as curl “isn’t found”. (‘which’ is about as a baseline of a command as there is.)



  • 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”.)





  • All good! It’s the same situation as I described and I see that increasing temps did help. It’s good to do a temperature tower test for quality and also a full speed test after that. After temperature calibration, print a square that is only 2 or 3 bottom layers that covers the entire bed at full speed or faster. (It’s essentially a combined adhesion/leveling/extrusion volume/z offset test, but you need to understand what you are looking at to see the issues separately.)

    If you have extrusion problems, the layer line will start strong from the corners, get thin during the acceleration and may thicken up again at the bottom of the deceleration curve. A tiny bit of line width variation is normal, but full line separation needs attention.

    Just be aware if you get caught in a loop of needing to keep bumping up temperatures as that starts to get into thermistor, heating element or even some mechanical issues/problems.


  • 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.)
