I have no skin in this game, but IPs are definitely not anonymous data. Also there is a lot of great info out there about de-anonymizing seemingly random data. Interestingly enough, this is similar to the Netflix prize dataset that was one of the more famous ones. Maybe a good introduction to that would be https://www.schneier.com/blog/archives/2007/12/anonymity_and_t_2.html

Nobody is gonna be using a quantum computer to “crack email hashes” of Plex users in a few years… I’m not even sure there is a speedup to hash cracking with quantum computers.

But depending on the hashing algorithm used, it’s likely pretty easy to crack hashes of email addresses today with a normal computer. They’re not particularly high entropy.

QEMU makes it pretty painless to hook up gdb just FYI; you should look into that. I think you can also have it provide a memory mapped UART for I/O which you can use with newlib to get printf debugging

I feel seen

Pretty much everyone I work with uses vim, emacs, sublime, or vscode. I like IDEs and use them for… well Java, but I wouldn’t argue that they’ve made the other tools obsolete or you’re a fool for sticking with the old ones. If it ain’t broke and all that. It actually seems like more people are moving back to pluggable text editors over IDEs

I’ve used AI tools a bit. They’ve really helped drop in code that would previously just be a bunch of TODOs; they get you up and writing the core parts much faster to see if the idea even works. They’ve also really helped answer specific questions or lead me towards the answer. They’ve also straight up lied to me quite a bit. It’s a weird tool.

I think the OP image is pretty wrong with the comparison it makes. LLMs/AI are a class of technology that are most definitely not going anywhere unless something dramatic happens. Some people, myself included, feel uneasy about the way they’re created and the fact that people in powerful positions completely misunderstand them, and I think that leads to the hope that they’re just a fad.

Could be a variable from somewhere else in the code. It should throw type error of some sort if it’s not going to handle a float correctly

TIL I didn’t realize Java used UTF16 for its internal representation. Looks like it’s a bit more complicated than that after Java 9 too

Android defaults to UTF16

In some build modes clang will simply put a trap where it sees undefined behavior. https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html

Not saying your wrong, just a fun fact I guess

Honestly I wouldn’t even go so far as home assistant. Do you have any IP cameras or just USB webcams? If you have IP cameras all you need is the VPN and then just access them as if you’re at home. If you only have USB webcams, you’re going to have to stream the content and I believe ffmpeg is actually capable of taking /dev/videoX and serving it over RTSP somehow, but I don’t remember exactly how. I see some references to it in some quick searches though. Maybe start here (some blog) or here (Stackoverflow question)?

Another thing to remember is that you’re going to be limited by your upload speed. If you’re not on fiber and in the US that’s likely going to be pretty bad, so set your resolution and the like accordingly.

Sorry about your cat. We typically have a Rover stop in to check on our cats when we’re gone for a bit; it’s nice to get them some human interaction and they always send pictures and give updates.

I personally have a camera setup inside that just streams to HomeAssistant so we can check on them ourselves when we’re out just for the weekend. I disconnect it when Rovers are stopping by though because I don’t want them to feel spied on. No need for anything fancy really, but if you really want NVR I just use Frigate (for other things, the cat camera really is just a stream). It’s free and open source and really easy to set up.

WireGuard is a very easy way to set up the access. My router has just the single WireGuard UDP port forwarded

You can use ~/.local/lib and LD_LIBRARY_PATH for shared libs.

Or better yet just give in and use the nix package manager, it is basically a virtual environment for your C programs.

Yes for example Python implements them using semaphores.

It doesn’t violate any rules… Imagine both the “speaker” and the “text” are being updated by separate threads. A program that would eventually display the behavior in this meme is simple, and I’m a bit embarrassed to have written it because of this comment:

#include <pthread.h>
#include <stdio.h>

char* speakers[] = {
    "Alice",
    "Bob"
};
int speaker = 0;

void* change_speaker(void* arg)
{
    (void)arg;

    for (;;) {
        speaker = speaker == 0 ? 1 : 0;
    }
}

char* texts[] = {
    "Hi Bob",
    "Hi Alice, what's up?",
    "Not much Bob",
};
int text = 0;

void* change_text(void* arg)
{
    (void)arg;
    for (;;) {
        switch (text) {
        case 0:
            text = 1;
            break;
        case 1:
            text = 2;
            break;
        case 2:
            text = 0;
            break;
        }
    }
}

int main(int argc, char* argv[])
{
    pthread_t speaker_swapper, text_swapper;

    pthread_create(&text_swapper, NULL, change_text, NULL);
    pthread_create(&speaker_swapper, NULL, change_speaker, NULL);
    for (int i = 0; i < 3; ++i) {
        printf("%s: %s\n", speakers[speaker], texts[text]);
    }
}
