Hi! So the other person completely demolished you, which is fine and none of my business, but it’s never a good idea to insult the person you’re debating against if you’re trying to change their opinion.

Nuclear is absolutely green! The reason that nuclear energy is popular is that it’s remarkably easy to convert an old coal power plant into a nuclear one, all you need to do is strip out the insides, maybe modify some stuff, but the overall structure can remain pretty much the same. Thorium reactors are also much greener than the existing Uranium/Plutonium ones, with Thorium being ~3x as plentiful in earth’s crust compared to uranium. Additionally, it doesn’t require much of the very expensive ventilation equipment for mines as it doesn’t produce radon gas when it decays. And the best part is that Thorium reactors are meltdown-proof. The thorium can’t fission on its own, it needs a helper material like Plutonium, meaning you can basically just flush the thorium away and it immediately stops the reaction.

Is it possible for devices to ask the pihole without doh, and the pi-hole to forward the request with doh if the domain isn’t in the cache?
- Comment on Chat Control 2.0: EU governments set to approve the end of private messaging and secure encryption 8 months ago:
I suppose you’re right, but forging that kind of thing would be difficult, also considering the PKI already in place. If someone has their own email server and they sign/encrypt their email, and host their public key on a key server somewhere, it’s highly unlikely that all three would be compromised. and even if that fails, you could just meet up with them and exchange flash drives with keys.

What’s stopping someone from just sending public keys or something through Signal and encrypting their messages that way? There’s no way to enforce this with such simple loopholes present. We shouldn’t be focusing on breaking privacy and instead invest in helping existing victims in ways that actually matter.

Holy shit (sorry)! You really know your stuff, or at the very least, I don’t know my stuff! I’ll keep in mind the stuff you said about the ESP32 and the ATMEGA, but I was more so referring to the editions of those dev boards that use the RP2040!

After reading a bit more, it seems that pretty much the only difference is the IO and other supporting hardware besides just the chips. If someone (me) were working on a project where solutions like these particularly-powerful microcontrollers are required, when would it make more sense to use one of these pre-made boards for computing rather than making your own PCB designs including the chip? Is it mostly for projects where extremely compact form factors (and/or other shenanigans) aren’t necessary?

Oh wow! this is a lot of great detail! is Rust at all useful for embedded applications, or am i essentially restricted to C/C++? Is Adafruit also a good resource or not as much as the others? Also, besides the obvious differences in form factor and ease of use, what’s the objective difference between the RP2040 chip, and, for example, Sparkfun’s “Pro Micro” or “Thing Plus”, or is the ease-of-use by itself the main selling point?

EEVblog looks great! lots of material there! glibg10b mentioned the book “The Art of Electronics”, is this a good source too?
- Comment on How should I get started? 8 months ago:
Probably stuff like microcontrollers/embedded applications! (I’d like to think) I already know much of the higher-level concepts of computers and how they work, I’ve messed around with programming in Rust or C#, I’ve been daily-driving linux for a few years, I’ve wrote software to do basic tasks for me, but my end goal is to apply my experiences to the physical world. I know very little about the basics of electronics, the physics of it, why PCBs are designed the way they are, etc.
I guess I’d like resources for the lowest-of-the-low-level stuff? Like “How electricity in general works”, “Use-cases for resistors”, “Why you sometimes see capacitors in weird places”, etc.
I’m just now realizing how vague my original question was? i’m sorry about that haha.
I don’t have a particular goal in mind though, i just think this stuff is cool, and I’d like to at some point be able to sit down and make something wacky or useful with KiCad/similar.
