"Such an object would usher in a revolution in computing"

The standard way to achieve what you're doing is to protect the share_ptr with a std::mutex. There is no easy way to provide a lock-free pointer to string. Such an object would usher in a revolution in computing.

LOL this revolution in computing would also destroy the job of a lot of senior engineers, but I don't think we'll see that happen anytime soon. –

-ffast-math

So what is fast-math?

It's a compiler flag or option that exists in many languages and compilers…

So what does it actually do? Well, as the name said, it makes your math faster.
That sounds great, we should definitely do that!

I mean, the whole point of fast-math is trading off speed with correctness. If
fast-math was to give always the correct results, it wouldn't be fast-math, it
would be the standard way of doing math.

ye olde "why don't they make the whole airplane out of
the black box"

i guess the retort is: if it's a tradeoff, why does "fast" get
to be in the name

like it's a tradeoff but only the upside gets in the name. i
mean maybe that's appropriate

could be hasty-math

High-Resolution Timing on the
Raspberry Pi

Just to be clear, this post is about measuring the times at which events happen. Making things
happen at specific times is a completely separate (and much harder) problem.

the wobbulation symbol and the Barker code…

synchronization symbol. Two synchronization symbols are proposed
to achieve frame synchronization for an OFDM, the wobbulation
symbol and the Barker code. These symbols are evaluated in AWGN
