Now, because this article got a little long, as per a friend’s suggestion, here’s a table of contents:

Optimization gives us optimal programs

Branch weights and the CPU’s branch predictor

-O3 produces much faster code than -O2

Javascript interpreters JIT at runtime because they don’t know which paths are hot ahead of time

If you have a compiler, you don’t need an interpreter

The middle-end is target/platform-independent

The compiler optimizes for data locality

-O0 gives you fast compilation

Templates are slow to compile

Separate compilation is always worth it

Why does link-time optimization (LTO) happen at link-time?

Inlining is useful primarily because it eliminates a call instruction

The role of the inline keyword

The best production compiler to study is LLVM

Undefined behavior only enables optimizations

The compiler can “simply” define undefined behavior 99% correctness rate is ok

Goodbye

Sorry you had that experience.

Even if you are an asshole you are presumably the same asshole. So maybe there is a difference in the moderators?

So fake

Great summary; thank you

Countries need to ban entry of any Russian citizens. Full stop.

They are a pariah state, and should be treated like one.

You might want to look at obtainium as a package source as well

I really like Stellarium on Android

Bevy is multiplatform, right?

So could one develop a keyboard mouse sharing tool (like barrier or synergy) with this?

I wish YouTube creators would pay a summary of their videos.

I’m not going to sit through YouTube ads to find out it’s something I don’t care about.

Who is better to decide what will help a person than that person?

It’s weird that conservatism rejects this simple idea that is just one side of the invisible hand of the market.

Ahh. Thanks for clarification.

A free demo does not belong in this sub

There should be a rule against posting this nonsense.

She may be a narcissist, and you might benefit from looking for r/raisedbynarcissists or the equivalent Lemmy community.

Why use a title with a metaphor that makes it impossible to know the meaning that’s intended?

Awesome! Glad it’s active!

Consider a chargeback if you bought it with a card

They will consider giving you your money back, and the merchant will eat it.

Emphasize that you don’t have what you paid to receive
