  • (The correctly used double negative was confusing for me at first, btw.)

    You make a very interesting point I haven’t ever thought about before.

    While I have always considered myself a patriot to a mild degree, I never associated it with tribalism directly. Even with the many faults of all countries, it’s OK to be proud of where you are from. (It does make perfect sense that tribalism is the end goal of state sponsored patriotism though.)

    In my mind, the fine line after patriotism was usually nationalism where tribalism runs deep and hate-based rhetoric becomes extremely effective. The definition of a patriot is somewhat twisted at that point. (ie: unless you believe [insert something random], you aren’t actually a patriot and therefore an enemy of the state.)

    I am not agreeing or disagreeing with you, btw. Your perspective is something interesting to think about, s’all. (I am leaning on the agreement side, FWIW.)

    (For the people reading this that may not realize that I am using the word “nationalism” in a negative context, I am. If that chaps your hide still, replace it with ‘christian nationalism’ or ‘white nationalism’ and fuck off. Everyone else, sorry for the disclaimer.)







  • You could probably map resonance artifacts, but you have to isolate layers that were printed at the same speed and direction. However, the second you tighten a belt or screw, that pattern will change and I am not sure how consistent resonance patterns would be on a bed slinger. (The quantity and density of printed plastic may change the resonant characteristics of the entire printer. This may be less of an issue on a core xy.)

    Thinking waaay outside the box… In some cases, I have seen extruder gear marks on the filament create artifacts on a print. Every gear pattern should be unique, but measurable differences would probably be micron or sub-micron.

    Maybe you could map the surface of textured beds as I seriously doubt that those patterns would be consistent and more prone to randomness from the factory.

    There are a ton of conditions that could generate unique artifacts on a print, now that I think of it. Hell, even a printers PID tuning can leave visible and repeatable errors.




  • Pin pitch is pin size and/or spacing. With physical plugs, you start to hit limitations with how small the wires can get while still being durable enough to withstand plugging/unplugging hundreds of times.

    Drop losses. (I am keeping this at an ELI5 [more like ELI15, TBH] level and ignore some important stuff) Every electronic component generates heat from the power it uses. More power used usually means more heat. Heat requires physical space and lots of material to dissipate correctly. Depending on the materials used to “sink” (move; direct; channel) heat, you may need a significant amount of material to dissipate the heat correctly. So, you can use more efficient materials to reduce the amount of power that is converted to heat or improve how heat is transferred away from the component. (If you are starting to sense that there is a heat/power feedback loop here, it’s because there can be.) Since a bit of power is converted to heat, you can increase the power to your device to compensate but this, in turn, generates more heat that must be dissipated.

    In short, if your device runs on 9v and draws a ton of power, you need to calculate how much of that power is going to be wasted as heat. You can Google Ohms Law if you would like, but you can usually measure a “voltage drop” across any component. A resistor, which resists electrical current, will “drop” voltage in a circuit because some of the current (measured in amperage) is converted to heat.

    I kinda smashed a few things together related to efficiency and thermodynamics in a couple of paragraphs, but I think I coved the basics. (I cropped a ton of stuff about ohms law and why that is important, as well as how/where heat is important enough to worry about. Long story short: heat bad)



  • Good luck with that, I suppose. Botnets can have thousands, if not hundreds of thousands of infected hosts that will endlessly scan everything on the interwebs. Many of those infected hosts are behind NAT’s and your abuse form would be the equivalent of reporting an entire region for a single scan.

    But hey! Change the world, amirite?



  • I don’t want to go so far as to tell you how to think, but as long as we are talking about how to visualize IP addresses, you may want to check out subnets and subnet masking.

    The notation of IP addresses starts to make sense when you think about the early days of TCP/IP when all IP addresses were public and NAT’ing wasn’t really required yet. Basically, there needed to be ways for networks to filter traffic by IP blocks that were applicable. (It was [in part] a precursor to collision avoidance, but absolutely not the full story.) We still use addressing and masking today, but it’s more obvious when it’s local. (Like in data centers, where it’s super practical to mask off a block of addresses for a row or rack of servers.)

    To your point, yeah. IP addresses are probably more comparable to the Dewey Decimal System rather than actual numbers and thinking of them as strings is probably easier.
