  • 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 mean, graded on a wide curve of history right now isn’t complete shit. WW1 saw entire generations of young men slaughtered uselessly at the hands of unelected kings. It was so horrific we actually still try not to use chemical warfare. Absolutely brutal combat with casualties that have hardly been seen since. Absolutely nightmare conditions. We baulk at the deaths of 25,000 over a few months of conflict where WW1 regularly saw those numbers in as little as a day. I do not want to minimize the absolutely brutal conflicts going on now. A newly orphaned child is not comforted by history, but your question seeks context and what else is history for but to contextualize the present?

    To me, history shows we have not even begun to experience the the depths of the horror people are capable of. At least in the states decenting voices are not carted away into slavery camps, actively trying to wipe out whole populations with starvation at least has some voices calling out the brutality, I do not see people trying to sell their children to survive like in the depression. These are not far away times where these things happened on a scale they do not now.

    Long story short, history has shown the measure of brutality and uncaring to be significantly worse at times. Raw and unquestioned genocide, slavery, persecution, war, child beating, women opressing, and all manner of the lowest acts of evil are the norm of humanity, not the relative peace we have known over the last 80 years. This fact does not make life suck less, but can at least act as a measure for how horrid is has been.



  • 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.


  • Well, it turns out only a handful of companies actually make image modules. I would say it is better in terms of US based support, firmware, hardware design, and the fact it meets TAA and buy America compliance. I’ve seen these cameras in the DoD and even in the oval office. If you want a camera that is absolutely not spying on you I can vouch for these because I have watched the firmware get built on these.
