Nobody who matters judges new shoes, but you can also extend the life of your shoes by resoling them before they get torn up. https://rockandresole.com/ does mail in resoling, but there could be a place near you. Huge savings considering the cost of shoes these days. I have a few pairs I rotate through while some are being resoled

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]);
    }
}

I’m relatively qualified. Studied physics all through college and spent a couple years working in quantum computing. I’ll chime in here because Schrodinger’s cat jokes are a pet peeve.

You are correct that, as far as we understand, it is literally impossible. There has been a competing theory for decades, but I’m not really up on the specifics https://en.wikipedia.org/wiki/De_Broglie–Bohm_theory. The reason it is generally rejected is that it appears to violate relativity.

Anyway… the cat thought experiment is such a fun thought experiment to me because it specifically makes us think about a very practical issue with respect to quantum computing: decoherence. If you take his thought experiment to an extreme, it actually should be theoretically possible to create a state in which a macroscopic object (the cat) and a quantum object (the radioactive source) are indeed entangled. But that is absurd according to everything we’ve ever seen. So what’s up? The missing concept here is decoherence – while this state may theoretically exist, it’d decohere on timescales so small we can’t even imagine. The fun connection here is that decoherence is the exact thing we’re trying to fight in quantum computing. Essentially we’re trying to make this thought experiment a reality for a much less complex system.

Yes I’m mostly familiar with this in Kotlin. Sometimes this is kinda a footgun because you’re writing multi threaded code without explicitly doing so.

Async features in almost all popular languages are a single thread running an event loop (Go being an exception there I believe). Multi threading is still quite difficult to get right if the task isn’t trivially parallelizable.

Yes, but if you can’t get your own modem it’ll at least stop you from having your traffic slowed down by the router side of their hardware

Don’t know you exact situation, but you should be able to bring your own modem (or modem/router combo) or put their provided unit into bridge mode

You can use udev to make a symlink with a consistent name

It’s not trivial on Fedora due to SELinux; you’ll need to use https://github.com/DeterminateSystems/nix-installer

Good explanation but a little nit: Colorado is a very purple state. We’re the home of Lauren Boebert and Focus on the Family after all.

I don’t think a Republican has won the presidential vote since GW Bush here though

This has always been a weird take, what do you think attracts people to that kind of SAR work? Generally a love for the outdoors and activities like this. You’ll have a hard time finding someone capable of high angle rescue that doesn’t enjoy or understand climbing as a sport.

I hate getting into these discussions.

This is Arnaud Petit and Stéphanie Bodet, two professional climbers with far more experience than you. They are doing the second ascent of a 900 meter 8a on Angel Falls (Rainbow Jambaia, 31 pitches) which is about the same height as El Capitan in Yosemite National Park. Here is a story about it. You almost never plan to climb routes this long in a single day, especially not on the second ascent. They most definitely planned to sleep on the wall and brought the proper equipment. This is called big wall climbing

Just be happy for people doing what they love and do what you love: your life will be better. We’re all motivated by different things.

They’re just having fun

Most responsible climbers bring something with them to pack it out, but there are some irresponsible ones that do what the comment above mentioned. That is the exception, not the rule though.

They were very clear it was for research in my memory. That was the reason I did it.

I’ve never had an issue using banking apps from Lineage. I use 3 different pretty mainstream ones

This is not necessarily true.

For example, consider the case of a 1Password vault falling into the hands of an attacker. They do not have the option to just crack your password, as the password is mixed with a randomly generated value to ultimately derive the key. They would need to simultaneously brute force your password and that random value. This should almost be impossible. However, given access to a client that already has knowledge of the secret value, it would fall back to brute forcing the password.
