And note that it's a good thing that crates are async, because async-in-sync using block_on has only some potential small CPU time overhead, while sync-in-async requires having a thread for each concurrent usage and has potentially cat

You can use `block_on` from the futures-lite crate (or from other crates) to synchronously call async functions. Not using async or async crates is not recommended since most new or updated high quality crates now use async.

Most CPUs don't have BCD math instructions, so you need multiple instructions, with probably around a 10-100x slowdown in math.

It looks like the Godot problem is that Chrome on Apple systems by default uses the native Apple OpenGL driver, which are broken, and can be worked around by passing --use-angle=metal to Chrome to tell it to use the new experimental Metal b

There's a simple trick to encode it: if there are less than 32 pieces, invert the bitboard (easily decoded since boards can't have more than 32), while if there are 32 pieces flip the board vertically (easily decoded because white

Seems really bad to me. There's a lot of distracting glitches like the K and Q having small gaps where strokes come together, and even glyphs like the N, M, Y and Z have weird little gaps at the joints, the F and B have a bizarre overh

Well, unless you absentmindedly type in your mail address, name or any other real credentials.

Presumably generated lots of variations of that sentence. It's 28 bits, so you only need to have around 14 places where 4 variations are possible. For instance, it could start with "Was", "I was", "verifying&qu

It says that it's actor-based, and sending messages to an actor is equivalent to running the actor function under a mutex, and thus reduces parallelism (in other words, you have N threads sending messages, but only 1 thread running the

That's because the author apparently neglected to parse the resulting page to ensure that the submission succeeded. If you terminate the system right after sending a form there is no guarantee that the data even left the local buffers

You can use impl Borrow<T> for that if the choice is static. If it's dynamic, you can use Cow or the supercow/bos/... crates if you want Arc/Rc to be options as well.

Rust is designed like this because it seeks to achieve zero-cost abstractions and safety. Or in other words, the goal is that you can think in abstract what the natural optimal machine code would be for a program, and you can write a Rust p

Do they really not do live migration or at least auto-restart (if configured) in those cases?

It's not clear, but my interpretation is that they contacted every account holder, somehow convinced them to migrate (perhaps with discounts and/or threats of termination) and then shut down once everyone migrated. Would be very i

OsmAnd, while a bit harder to use (but not that much), is much better than Organic Maps: it can show satellite imagery from both Google and Microsoft (and download it for offline use!), has a 3D map view, supports coloring slopes, has a bun

Seems easily avoidable by having the modules rendezvous in one of the myriad ways that are possible given that both run in kernel mode with full privileges. For example, you can walk the kernel-only page tables, find all executable pages, a

Rust is the best programming language, so the question is more why you wouldn't use it. And the answer is you wouldn't use it if there's a library or existing codebase in another language that is much better than the Rust equ

The article claims that Apple's compiler doesn't use the instruction, so it seems like the compiler author did indeed forget or never learn about it.

Trucks drive just fine with no rear view at all other than side mirrors, so cars can do that as well.

That also suffers from integer overflow if they implement it naively as they seem to show in the blog with a `pub trait Modification: PartialEq + Default + Add<Output = Self>` and using primitive integers.

T&& doesn't run the T destructor when it's destroyed, which is the whole point of unique_ptr.

That's obviously infeasible (either it would be bad or it would cost too much time/money). However, maintaining a variant of Ungoogled Chromium or Vanadium targeted at desktop Linux would be feasible.
