Interesting benchmark on pointers vs. indices, relevant to Rust code which for borrow checking reasons tends to use indices a lot: https://t.co/wiWg9iUQAS

tl;dr you pay 1 cycle penalty for address computation, but indices can be 32-bit instead of 64-bit, which can be a big win.

@steveklabnik What is wrong with indexes ?

It's been a while since I wrote anything so I wrote an article on how to discover the entire x86-64 instruction set in seconds including any hidden instructions and learn their basic properties while on it. There were some pretty interesting results!

@ryan_levick Not sure but it might be related to the scheduler prioritizing the video & sound ?

4/ So Apple simply cheated. They added Intel's memory-ordering to their CPU. When running translated x86 code, they switch the mode of the CPU to conform to Intel's memory ordering.

I thought there might be something nice in https://t.co/gCsVbkY6Vj, but I didn't expect such a nice result.
