Maybe I’m wildly misunderstanding something, not helped by the fact that I work very little with Web technologies, but…

So, in a RESTful system, you should be able to enter the system through a single URL and, from that point on, all navigation and actions taken within the system should be entirely provided through self-describing hypermedia: through links and forms in HTML, for example. Beyond the entry point, in a proper RESTful system, the API client shouldn’t need any additional information about your API.

This is the source of the incredible flexibility of RESTful systems: since all responses are self describing and encode all the currently available actions available there is no need to worry about, for example, versioning your API! In fact, you don’t even need to document it!

If things change, the hypermedia responses change, and that’s it.

It’s an incredibly flexible and innovative concept for building distributed systems.

Does that mean only humans can interact with a REST system? But then it doesn’t really deserve the qualifier of “application programming interface”.

I can’t remember if threads are core bound or not.

On Linux, by default they’re not. getcpu(2) says:

   The getcpu() system call identifies the processor and node on which the
   calling thread or process is currently running and writes them into the
   integers pointed to by the cpu and node arguments.  ...

   The  information  placed in cpu is guaranteed to be current only at the
   time of the  call:  unless  the  CPU  affinity  has  been  fixed  using
   sched_setaffinity(2),  the  kernel  might  change  the CPU at any time.
   (Normally this does not happen because the scheduler tries to  minimize
   movements  between  CPUs  to keep caches hot, but it is possible.)  The
   caller must allow for the possibility that the information returned  in
   cpu and node is no longer current by the time the call returns.

And Fabrice Bellard, the original author of ffmpeg, went on to create qemu which pretty much made open-source virtualization possible. Also TCC (even if I don’t think that one is widely used), he established a world record for computing decimals of Pi using a single machine that had ~2000× less FLOPS than the previous record, and so much more…
