  • Could be as simple as a sensor. If there are other engine codes, that could mean a bigger issue. The obvious first steps are to check if the cat is actually still there or if wires to the sensors are damaged.

    Catalytic converters can last a long time unless combustion issues or other serious engine problems are ignored. TBH, catalytic converter codes are generally just a symptom of something else. So, do as detailed of an inspection as you can for any wiring damage or leaks. If you have any leaks, try your best to identify the kind of fluid it is. Maybe you can get a hint about what else is going on.

    Combustion control is horrendously complex, so it could be any number of things from bad spark plugs to a malfunction in the EGR system. Any information you can gather about the problem now may save you some time and money later.

    (I dunno if you know anything about cars, but I just covered the basics, just in case.)



  • (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.)







  • Without going into much detail about my experiences, it turns out this scenario stemmed from them being bipolar. Anecdotally, when they got diagnosed and treated, this behavior stopped and they were able to express frustration without going full manic. (I don’t fully understand bipolar’isms that well myself, btw.)

    It’s OK for someone to be frustrated. It’s OK for someone to get mad at you on occasion. It is not OK to be yelled at for hours over something absolutely trivial.

    Don’t jump to any conclusions if you are in a similar situation. The person may actually be abusive!




  • 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.
