  • While I agree that it’s not exactly the same, there is a lot of overlap. It’s also more complicated than the OP presented.

    Since everyone here is refusing to do even a basic search, here is one on the first page of Google results.

    An individual’s response to natural rewards, such as sex, is largely regulated by the mesolimbic dopamine pathway, which receives excitatory and inhibitory input from other limbic structures and the prefrontal cortex [64]. Erections are dependent upon activation of dopaminergic neurons in VTA and dopamine receptors in the NAc [65,66]. Excitatory glutamate inputs from other limbic structures (amygdala, hippocampus) and the prefrontal cortex facilitate dopaminergic activity in the VTA and NAc [62]. Reward responsive dopamine neurons also project into the dorsal striatum, a region activated during sexual arousal and penile tumescence [67]. Dopamine agonists, such as apomorphine, have been shown to induce erection in men with both normal and impaired erectile function [68]. Thus, dopamine signaling in the reward system and hypothalamus plays a central role in sexual arousal, sexual motivation and penile erections [65,66,69].

    We propose that chronic Internet pornography use resulted in erectile dysfunction and delayed ejaculation in our servicemen reported above. We hypothesize an etiology arising in part from Internet pornography-induced alterations in the circuits governing sexual desire and penile erections. Both hyper-reactivity to Internet pornography cues via glutamate inputs and downregulation of the reward system’s response to normal rewards may be involved. These two brain changes are consistent with chronic overconsumption of both natural rewards and drugs of abuse, and are mediated by dopamine surges in the reward system [70,71,72].

    […]partnered sex no longer met their conditioned expectations and no longer triggered the release of sufficient dopamine to produce and sustain erections

    The word dopamine appears 54 times in this article, and overall seems to agree with the OP.

    Please be better than this. It’s the mirrored version of ‘owning the libs’, and it hurts us all in the end.

    That said, I am very pleased that justice has been served. We need to hold more politicians accountable, both at the polls and in the courts.










  • Not THE issuer. AN issuer. All of your devices have a number of trusted top-level issuers (Root certification authorities). Windows has about 50 preloaded, and this list largely matches what you’ll find on Android, Mac, etc. Everyone’s been mentioning Let’s Encrypt, which descends from ISRG Root X1. But you can (relatively) easily get certs from Thawte, Verisign, and many others.

    And if none of those are to your liking, you can install your own. Seriously, there’s nothing technical stopping you. Most corporate devices (Windows, Mac, Linux; Android or iOS; mobile, client, server) have the company’s root certs installed. The challenge for public trust is exactly that- Trust. You must operate in a way that is generally trustworthy.

    Let’s Encrypt was actually pretty revolutionary. You aren’t entirely off base with your concern. Prior to that, getting a cert that was trusted by most devices was non-trivial, and came with an expense. But that wasn’t because of the desire for encryption. Rather, it was about verifying that you were who you said you were. These also served as proof of identity.


  • You don’t create power; you convert it and harness it. In an ICE, you convert chemical energy (gas or similar) into kinetic energy (explosion, turning a crankshaft, and rotating the wheels. Plus some of it going into the alternator) and heat, with a considerable amount still left as unused chemical energy (largely in the form of exhaust/soot)

    If you separate parts of the process (such as splitting water into hydrogen) the pieces you are looking at (burning hydrogen as fuel) could be very useful. You’re still converting chemical energy into kinetic energy and heat, and that may (or may not) be a better system than carrying around an electric battery with that same amount of energy.

    There is simply no way to start with water, perform a series of self-contained chemical reactions ending back with water, and having more energy than you started with.




  • You’re overlooking a very common reason that people setup a homelab - practice for their careers. Many colleges offer a more legitimate setup for the same purpose, and a similar design. But if you’re choosing to learn AD from a free/cheap book instead of a multi-thousand dollar course, you still need a lab to absorb the information and really understand it.

    Granted, AD is of limited value to learn these days, but it’s still a backbone for countless other tools that are highly relevant.
