Hi,
I'm in the middle of writing a multi-user system with very
critical timing issues. I've already implemented a cache and an API to
access it (with appropriate locking for multithreaded access). This

defined shared mem space. But here you have many many objects being
shared. Having a VM...

I've searched google intensely on this topic and it seems noone really knows how to approch this.
The goal I don't want clients to give out their usernames and passwords to friends, since the site
relies on subscrption fees.
Sessions ID's are matched between the browser and the server. So a users can login with same
username and password and those sessions are tracked individually.
Some suggest create table fields with the session ID...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
