  • How are finishes so durable and thin?

    My assumption of a lack of post processes is because I come from a background of automotive refinishing and repair, where I’ve owned a shop and painted for many years along with getting into custom art graphics and airbrushing. The only finishes I know of that provide a similar durability are two part urethanes. Those are far too thick by comparison. When cutting into plastics that have been moulded, the finish shows no signs of mechanical layering or bonding like a post process finish in most cases. Often a cleanly broken or cut part shows a similar type of penetrating surface alteration I associate with a polishing operation, where the surface transitions in color and grain structure with in millimeter or few (in cases where the break is clean and does not appear to be influenced by stress alterations like ABS where it whitens under tension).

    How does chromate conversion work with a prep regime and what kind of wet paint can offer similar durability to a 2k urethane when it is impossibly thin? Like I know the limitations of urethane well when it comes to corners and pointy bits where it will thin from surface tension. There is not a chance in hell that the buttons on the side of my phone could be painted with such a finish with an even conformal coating and remain durable for years of constant abrasion. Is there a name for this class and type of finish? Where are they sourced? What is the scale of the industry? Is there a way to access the process and products at a small scale?


  • They told us they were going to invest in EV R&D back in 2014. You know, back before we had that orange anal experience of a Russian puppet wannabe pornstar felon president. We put 6b into GM to compete; they pumped their stocks with it. Such is 3rd world America. Lay off the McCarthy bullshit whining about investing in R&D to mask corruption and ineptitude. This was no fucking surprise. Spinning this bullshit is just trying to justify screwing over average Americans with overpriced undeveloped bloated unaffordable garbage made to pad our useless incompetent oligarchy’s pockets.




  • Slowly trying to learn sh while using mostly bash. Convenience is nice and all, but when I encounter something like OpenWRT or Android, I don’t like the feeling of speaking a foreign language. Maybe if I can get super familiar with sh, then I might explore prettier or more convenient options, but I really want to know how to deal with the most universal shell.


  • Yeah, but depends on a person’s goals. I don’t mind being doxed. The privacy thing I’m really concerned about is manipulation of data related to the host server; apps that are used like data loggers of sensors; tracking dwell time; page views; likes, blocks, etc. I care far less about what I say to others in public. I vehemently claim that owning the data about any individual is theft of autonomy, failure of democracy and government, and a form of slavery if one plays out the total philosophical circumstance and implications. Anyone that holds such data about someone else with the intent to manipulate in any way whatsoever is a criminal. I’ve been a Buyer for a retail chain, collected and analysed tons of customer data. This has nothing to do with how data is collected and used now, but this is used as justification for the present criminal data manipulation industry.

    As a disabled person, I need to connect with humans more, and as much as I can here. I totally respect those of you that have other priorities that limit your conversational topics of interest, and I don’t wish to violate those. This place is just my version of a public square, where I’m trying to make general conversation. -warmly








  • Adding to what others have already mentioned… Most of the gold will be from various collisions of external objects. The vast majority of the gold and other heavy elements are in Earth’s core due to gravitational differentiation.

    There is a volcano (in South America IIRC) that has unusually high gold content, but it is from the underground magma reservoir coming in contact with gold deposits. This is why space mining is a really big deal. The Earth is a resource poor gravity prison by comparison. The wealth in space is enormous compared to any differentiated body.

    Gold is actually everywhere and relatively common, but only in very small quantities. Under the right conditions, the weight can help gold to concentrate and fall out of solution when that solution was once covering a very large area, dissolved the tiny bits of gold found all over a large area, and then pools into a low point over extremely long periods of time.


  • I found a Python project that does enough for my needs. Jq looks super powerful though. Thanks. I managed to get yq working for PNG’s, but I had trouble with both jq and yq with safetensor files. I couldn’t figure out how to parse a string embedded in an inconsistent starting binary, and with massive files. I could get in and grab the first line with head. I tried some stuff with expansions, but that didn’t work and sent me looking for others that have solved the issue better than myself.
