  • 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.

    I have an old Lenovo W550s Thinkpad with a 2GB Dedicated Nvidia and an i5 5500U. It’s got two batteries and sips power. It’s only 4 cores, but for what I run it does great. I get fairly consistent 60fps on low settings for “boomer shooters” like Selaco. The thing is an absolute beast and hardly flexes. The plastic is cracked and I can just hand it to my kids without a care in the world. Dump a drink on it, drop it, I could care less. I had them help me change out the RAM and SSD because it’s essentially bound for the dumpster and any value I get out of it is the cherry on top.

    That and I can run pretty much and retro gaming console on it to about the Wii/GameCube, which blows my mind. All for probably like $200 of hardware.

    It consistently ran slower on a few benchmarks I care about like language model performance, which was surprising. Baulders Gate was also jankyier for some reason. I love that people are out trying to do this stuff and the community was nice. Just like anything the reality is often less exciting than the marketing. It is bundled together arch with some hopeful optimizations that I am certain will work for some hardware and some applications, but not all hardware and all applications.




  • Well if you are doing work on you computer you find rewarding and it functions I would quit while you are ahead. Getting into distro hopping and caring about Linux internals is a bit like being a car enthusiast. You can either have a car to drive it or have a car that you fart around all the time tweaking bits, replacing it, breaking it, developing strong opionons about things almost no one cares about.

    So to you want to be a driver or an enthusiast? By using Linux at all you can essentially consider yourself part of the “car club”, but there is a whole heck of a lot else to learn.



  • I swear it is my machine or something, but despite CachyOS claiming being faster and more optimized I have yet to benchmark it as faster than the stock kernel for things I play around with. I wrote an application in rust to process a large text file and it both compiled and ran slower on CachyOS. I play around with llama.cpp and again it compiles and runs slower on CachyOS. I want to like Cachy, but right now all I can see is a bunch of window dressing to stock Arch with KDE and a couple of themes that I would rather change to default.

    Also, why in the hell am I being asked to make a wifi password encryption key with the damn USB installer? CachyOS is not the only one. A lot of KDE using distros pop up the encryption window when you setup WiFi on the install image. Why? You want me to temporarily encrypt my wifi password on a temporary live image??? I just slows me down.

    Anyways, I’m sure I’m crazy and clearly it is fast for somebody, but I can’t even get games to benchmark higher.


  • I’ll take something from 2005 as a compliment to Linux Mint. Having installed it in 2006 you are absolutely correct. It’s shockingly boring lack of constant UI paradigm shifts almost makes me forget about the OS completely. I’m at the point in my Linux journey where I see slow adoption of new things as good. I accept others have setups that mint does not work for, but I would wager there is no Linux DE better suited as a first suggestion to try depending on the newness of the hardware. If you have 5 monitors of differing resolutions and frame rates then sure, there are better DEs.



  • 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.
