  • A whole bunch of welds in nuclear reactors are visually inspected using cameras duct taped onto the end of incredibly long poles which also get duct taped together. This would be the inside of BWR plants near the fuel and jet pumps. There is also an “art” to moving the cameras and poles around to get the shots you need. And if you get stuck the talented people know how to get you unstuck. There are also cameras just duct taped to ropes that the camera handler “swims” to certain spots.

    Don’t get me wrong, we have cool ultrasonic inspecting robots as well, but I was absolutely blown away by what visual inspection looked like in practice.

    PS: The high dose fields make the camera look like it is being blasted with colorful confetti because of the high energy particles bombarding the camera module.





  • You can either count blessings or curses. Both you can probably count endlessly if looked at hard enough. I cannot deny that threats loom over my life such as climate change, totalitarian thinking, gun violence, and a whole host of other ills that I feel completely incapable of impacting. Consider me the boiled frog. I cannot live my life in constant anxiety and fear. I have good things, good things happen to me, today I can breathe, today I can walk. I woke up in my own bed with a healthy body. Tomorrow I am unlikely to be blown up by an artillery shell or to executed by some brown shirt goon of an evil regime.

    I can hold both the evils of the world and the good of it in my mind at once. I agree one must not grow complacent at the things that go on. But I also must not become paralyzed by the overwhelming number of things going wrong. At least that is me.


  • I find great comfort in history personally. Dan Carlin (a favorite podcaster of mine) always says we must grade history on a curve. Sure, to us it looks like everything is falling apart and existence is pointless. But by very real measures things are better than they have ever been. My favorite is violence against children has been normalized as being bad.

    Within living memory it has gone from being completely socially acceptable to beat children as being the preferred method of parenting to people getting thrown in jail for that behavior. What does it mean that previous to 100 years ago all of society could have been considered battered children? We are extremely aware of the negative effects of violence against children and for the very first time we are seeing a generation raised in an environment that kind of behavior has carrots and sticks motivating parents to behave properly. Of course all manner of horrid things still happen, but I call it progress that it have become widely condemnable to beat a child with a stick or take them to public hangings. It’s a small victory, but it gives me hope for the future. That we may yet still build a better human being capable of taking on the heroic task of fixing this world.

    Further, history has shown to me low points that I am glad to have missed. I never knew how ghastly WWI was. I am currently in a warm bed and not in a trench filled with mud, flys, dead body parts, with shells exploding constantly, seconds away from needing to charge out into near certain death. But my great grandfather knew that feeling. He watched as whole generations of young men were gassed to death and blown up uselessly. The numbers who die in war are less now. Still tragic, but less. Again, we must grade on a curve.

    Death, despair, and hopelessness may be in 8K live streamed constantly now, but I assure you the analog version was something to behold. Not saying the horror of the past makes living any easier now. It is not to minimize your own pain. I just find hope that others managed to break the back of an unshakable world and hope for a better one while surviving a suffering I have not yet known. I am made of the same stuff. That gives me strength.



  • I was a tutor in college and have been working for over a decade at this point in professional settings. I would gladly substitute aptitude with a proper attitude most days. Showing up to work, presenting more potential solutions than just problem identifying, and a willingness to learn will get you further than aptitude. Nobody has aptitude in Autodesk 2023. Nobody has aptitude in ultrasonic non destructive weld testing. You need to learn, be willing to learn, and be willing to try. It does not hurt to be able to communicate strongly either.

    What you are strong in can also just be what you are not weak at. Finding all the things you struggle with is just as useful. Don’t expect to find “The thing” you are just gifted at. Far better to be resilient and accept failure as it comes and learn. Natural talent is only a small part of the equation unless you are in sales.





  • It’s the way of things. When things are new the tech can be understood and seen. You also have to know how to fix it early on and because it is simple you usually cloud. Old cars, the first electric devices, hell even some of the first radios were being built in the field. Fixing a phone looks as close to magic as most normal humans see. Everything is so damned small and complicated even the smallest part would be difficult to replicate and replace. I love old tech because you could grasp the whole with your mind and see it work.
