This setting appears to work for me. It shows up as blocked in the logs. I've also blocked it in NoScript for good measure.

I assume it's because many people outside the USA are accustomed to taking off their shoes when entering a house or apartment.

According to GitHub, development of DevToys predates it-tools by a year. If anything, I'd say they're both inspired by CyberChef.

How big is the context window for the free version? I haven't found any information about it.

I use stars to keep a list of repositories I'm interested in. You can even put them in different categories, like browser bookmarks.

Is a dereferenced reference not equal to the original variable? by b_van_b in c/rust@programming.dev

[-] b_van_b@programming.dev 1 points 1 year ago

Thanks for the detailed explanation! I guess the main takeaway is that a reference can never be converted back into an owned value. Later content in the book also gave more information about when you have the right to transfer ownership.

Is a dereferenced reference not equal to the original variable? (programming.dev)

I'm going through the interactive version of The Book, and I'm confused by the results of an exercise in Ch 4.3 - Fixing Ownership Errors.

The following code does not work, and they say it's because it would result in the same heap space being deallocated twice:

fn main() {
    let s = String::from("Hello world");
    let s_ref = &s; // reference s
    let s2 = *s_ref; // dereference s_ref
    println!("{s2}");
}

But in my mind, this should be equivalent to the following compilable code, which transfers ownership of s to s2 :

fn main() {
    let s = String::from("Hello world");
    let s_ref = &s; // reference s
    let s2 = s; // move s directly
    println!("{s2}");
}

If s_ref is a reference to s, then dereferencing s_ref should return the String s, shouldn't it? Why can't s be moved to s2 with either the above code or let s2 = *&s;, which fails in the same way?
