This limitation is to ensure that the two functions use the exact same calling convention (input & output registers, and values passed via stack). It can depend on the particular architecture.

There are many situations where those little differences completely vanish because of instruction pipelining. Only way to know is to actually measure it.

I'd love to see performance numbers for this, if they're available. My hunch is that indexing cost would be about the same.

Does it have to move or resize when one of the sides reaches the end of the array? I presume that would be slower than a ring buffer that only grows when it's completely filled?

For context: a VecDeque is a ring buffer backed by an array.

This article is one my pet peeves. It always shows up in discussions as "proof" that 0 indexing is superior, but it hides under the carpet all the cases the where it is not. For instance, backwards iteration needs a "-1"

In theory, everyone would be able to take an informed decision. In practice, patients wold rather take action than wait, resulting in harm from unnecessary exams and interventions. Not to mention the cost of the exams themselves. Everytime

The big problem with the broad spectrum exams is the "if appropriate" part. Often it's not clear if further exams or interventions are warranted, and when in doubt people tend to err towards taking action.

I started using Typst this year and am really liking it so far. The rendered document updates as you type, and it's easier to code grid layouts. I like how I don't need to be paranoid about adding "%" at the end of lines

Basically, electromagnetic force is much stronger than the sun's gravitational force. (But it's also more difficult to get it to eork just right)

Regardless, on average it tends to work out. The amount of iodine in the salt is regulated by measuring uring samples in a large population.

The most common kinds of hypothyroidism are due to the thyroid being damaged. Adding iodine can't help, but there are several known ways it can be harmful.

Notably, a lot of non-table salt in the US is not iodized. So the amount of iodine someone gets depends on how much of their food is industrialized, vs home cooked.

Absolutely not!! A single drop of Lugol's iodine has dozens of times the deily recommended amount of iodine, and such levels have been documented to cause harm to the thyroid. Including inducing hypothyroidism. To quote the American Th

by ufo 2y ago
I think it's a United States thing. There are other countries where all salt meant for human consumption must be iodized.

A foreign function interface that's based on parsing C files must translate C types and interfaces into types and interfaces of the target language. I suppose it helped that D's type system has many similarities with C, including

by ufo 2y ago
I know that in other languages, one obstacle for "just compile the C files" is that the target language might not have pointers and thus have difficulty representing things such as return-by-pointer. I suppose in D this was less o

IIRC, LuaJIT also doesn't like native code. Most native calls will cause LuaJIT to fall back to the unoptimized interpreter, with the exception of some special-cased functions from the standard library. https://chrisfls.gith

The stack's still there. I agree that reference manual's notation for how many values are pushed and popped can take a while to get used to, but at least it's straight to the point. One trap with the stack is that it baits yo

Have you seen the Passing a Language Through the Eye of a Needle article, from the Lua authors? It talks about how some of unusual the design decisions such as pcall error handling and the stack are tradeoffs in favor of "embeddability

The new register-based virtual machine still uses the same stack under the hood. The only difference is how instructions are encoded in the bytecode. By default they can read and write to any position in the stack as opposed to pushing and
