Ever heard of Mr. Hands?

This is a use-after-free, which should be impossible in safe Rust due to the borrow checker. The only way for this to happen would be incorrect unsafe code (still possible, but dramatically reduced code surface to worry about) or a compiler bug. To allocate heap space in safe Rust, you have to use types provided by the language like Box, Rc, Vec, etc. To free that space (in Rust terminology, dropping it by using drop() or letting it go out of scope) you must be the owner of it and there may be current borrows (i.e. no references may exist). Once the variable is droped, the variable is dead so accessing it is a compiler error, and the compiler/std handles freeing the memory.

There’s some extra semantics to some of that but that’s pretty much it. These kind of memory bugs are basically Rust’s raison d’etre - it’s been carefully designed to make most memory bugs impossible without using unsafe. If you’d like more information I’d be happy to provide!

That’s the point. Malicious compliance.

You’re looking for Fred Rogers, more commonly Mr. Rogers. He was the host of the popular children’s show Mister Rogers’ Neighborhood, and is revered for having been incredibly compassionate both in public and private.

I was very intrigued by a follow-up to the recent numberphile video about divergent series. It was a return to the idea that the sum of the integers greater than zero can be assigned the value -1/12. There were some places this could be used, but as far as I know it was viewed as shaky math by a lot of experts.

As far as I recall the story goes something like this: now, using a new technique Terrence Tao found, a team was seemingly able to “fix” previous infinities in quantum field theory - there’s a certain way to make at least some divergent series work out to being a real number, and the presenter proposed that this can be explained as the universe “protecting us” from the infinities inherent in the math.

It made me think about other places infinities show up in modern physics (namely, singularities in general relativity) and whether a technique something like this could “solve” them without a whole new framework like string theory is.

Even as an (older) zoomer in the US, this was never a thing for me. No one cared what phone you used. If you had an Android you wouldn’t be in iMessage group chats but no one judged you for it.

The issue is that, in the function passed to reduce, you’re adding each object directly to the accumulator rather than to its intended parent. These are the problem lines:

if (index == array.length - 1) {
	accumulator[val] = value;
} else if (!accumulator.hasOwnProperty(val)) {
	accumulator[val] = {}; // update the accumulator object
}

There’s no pretty way (that I can think of at least) to do what you want using methods like reduce in vanilla JS, so I’d suggest using a for loop instead - especially if you’re new to programming. Something along these lines (not written to be actual code, just to give you an idea):

let curr = settings;
const split = url.split("/");
for (let i = 0; i < split.length: i++) {
    const val = split[i];
    if (i != split.length-1) {
        //add a check to see if curr[val] exists
        let next = {};
        curr[val] = next;
        curr = next;
    }
    //add else branch
}

It’s missing some things, but the important part is there - every time we move one level deeper in the URL, we update curr so that we keep our place instead of always adding to the top level.

If anybody’s curious, I tried it with GPT4 and it got it right.

The GPU I used is actually a 1080, with a (rapidly declining in usefulness) Intel 4690k. But I suppose laptop vs desktop can certainly make all the difference. What I really want is GPU virtualization, which I’ve heard AMD supports, but I’m not about to buy a new GPU when what I’ve got works fine.

My experience with single GPU passthrough on Proxmox to a media VM was pretty positive, especially for it being an old Nvidia card. Even as someone doing it for the first time, it just took about 10 minutes to figure out the passthrough itself and another ~15 to figure out some driver issues. And it’s worked perfectly since then. All in all much better than what I’d expected.

Besides rendering bugs that may or may not be Safari’s fault, I wanted to get uBlock Origin on an iPhone but it’s not available, IIRC because the content blocking API is more restrictive than what uBlock is designed for.

They’re welcome to retaliate. They’re just not allowed to indiscriminately bomb civillian infrastructure.

Here’s a field manual that details the rules and has some advice. There are a whole host of rules protecting civillians hospitals, but in the case where Hamas is using them as military bases, I’d say they can be considered primarily as human shields, though I’m no expert, and even if that’s not the case they’re still civillians and therefore protected. According to paragraph 2-20, “feasible precautions” must be taken to reduce civillian harm. This means bombing is pretty much out of the question, but there are still plenty of other ways to get at Hamas, such as SpecOps, sieges, and diplomacy. It’s a difficult situation, but that doesn’t mean you get to kill civillians with impunity.

Yeah personally I haven’t needed jQuery in years.

I was even kind of interested, but then I got further in the main quest and figured out what the ending is…

Then I felt like there was no point to anything I did.

Having made the choice to use GTK for a Rust project years ago - before a lot of the more Rust-friendly frameworks were around - this is exactly why I chose it. Nothing to do with DEs or any of that, just looking for a better coding experience. Now I’d probably choose one of the several Rust-focused solutions that have popped up though.

The issue is not just that a bad update went out. Freak accidents can happen. Software is complicated and you can never be 100% sure. The problem is the specifics. A fat finger should never be able to push a bad update to a system in customers’ hands, forget a system easily capable of killing people in a multitude of ways. I’m not quite as critical as the above commentor but this is a serious issue that should raise major questions about their culture and procedures.

This isn’t just some website where a fat finger at worst means the site is down for a while (assuming you do the bare minimum and back up your db). This is a vehicle. That’s what they meant about the CAN bus - not that that’s really a concern when the infotainment system just gets bricked, but that they have such lax procedures around software that touches a safety-critical system.

Having systems in place to ensure only tested, known good builds are pushed is pretty damn basic safety practice. Swiss cheese model. If they can’t even handle the basics, what other bad practices do they have?

Again, not that I think this is necessarily as bad as the other person - perhaps this is the only mistake they’ve made in their safety procedures and otherwise they’re industry leaders - we don’t know that yet. But this is extremely concerning and until proven otherwise should be investigated and treated as a very serious safety violation. Safety first.

Currying is converting a function with n parameters to n functions that each have one parameter. This is done automatically in most primarily functional languages. Then, partial application is when you supply less than n arguments to a curried function. In short, currying happens at the function definition and partial application happens at the function call.

Currently the type of test_increment is (int, int) -> unit -> unit. What we want is int -> int -> unit -> unit. The more idiomatic way would have this function definition:

let test_increment new_value original_value () =

Which would require this change in the callers:

test_case "blah" `Quick (test_increment 1 0);

See, in most primarily functional languages you don’t put parentheses around function parameters/arguments, nor commas between them - in this case, only around and between members of tuples.

I’m not an OCaml person but I do know other functional languages. I looked into Alcotest and it looks like the function after “`Quick” has to be unit -> unit. Because OCaml has currying, and I think test_increment already returns unit, all you should have to do is add an extra parameter of type unit. I believe that would be done like this:

let test_increment (new_value, original_value) () =

Now the expression test_increment (1, 0) returns a function that must be passed a unit to run its body. That means you can change the lambdas to e.g. this:

test_case "blah" `Quick (test_increment (1, 0))

I don’t know OCaml precedence rules so the enclosing parentheses here may not be necessary.

I’d also note that taking new_value and original_value as a tuple would probably be considered not idiomatic unless it makes sense for the structure of the rest of your code, especially because it limits currying like we did with the unit being able to be passed later. Partial application/currying is a big part of the flexibility of functional languages.

Edit: if you’re getting into functional programming you may also consider calling increment_by_one “succ” or “successor” which is the typical terminology in functional land.

No, and the above commentor is a little mixed up. While we originally thought the benefit of RISC CPUs was their smaller instruction set - hence the name - it’s turned out that the gains really come from a couple other things common to RISC architectures. In x86 pretty much every instruction can reference memory directly, but in RISC architectures you can only do it from a few specific instructions. Modern RISC architectures actually tend to have a lot of instructions, so RISC means something more like “load/store architecture” nowadays.

Another big part of RISC architectures is they try to make instruction fetch+decode as easy as possible. x86 instructions are a nightmare to decode and that adds a lot of complexity and somewhat limits optimization opportunities. There’s some more to it, like how RISC thinks about the job of the compiler, but in my experience load/store and ease of fetch+decode are the main differentiators for RISC.

More towards your question, a lot of the issues with running x86 programs on ARM (really running any program on a different architecture than it was compiled for) is that it will likely depend on very specific behaviors that may not be the same across architectures and may be computationally expensive to emulate.
