This was really frustrating me. YT started recommending this channel and I could recognize the voice as an AI impersonation but had no way to know if it was at least reading something really written by Feynman. Eventually I concluded it wasn't, but there wasn't clear criteria under which I could report the channel. I'm not sure it's even against YT's TOS.
I think you're not technically wrong, but you're defining NAT differently than the majority of people you're arguing with (those who assume NAT also implies a firewall blocking inbound connections), and the remaining minority (the "on the WAN subnet" crowd) are dismissing outright the idea as a reasonable attack vector that an attacker close enough to be able to send packets destined for non-internet routable addresses to your router.
Is the latter something that was/is actively exploited?
It's there in the name - "Rust graphics community" as opposed to simply "the graphics community". Language fetishization above the end goal - or, rather, the language fetish is the real goal.
If gRPC overhead is critical to your system, you've probably already lost the plot on performance in your overall architecture.
You make a fair point about smart pointers, and median "modern C++" practices with STL data structures are unimpressive performance-wise compared to tuned custom data structures, but I can't imagine that idiomatic Java with GC overhead on top is any better.
You can try, but so many games have been released half-finished, never subsequently completed via patches, and as a result sunk their studio and the whole franchise they were a part of. Games that should have become classics instead remain half-finished, mostly forgotten messes, and all the work those people put into the game are wasted in the long run. Why? To meet a holiday ship date?
