namespaces

Systemd 220 adds support for user namespaces so you can run nspawn containers as non root users.

It's probably not going to grok C++ member declaration syntax, templates, namespaces, and so on.

Folks coming from many non-JS language will have been exposed to modules/namespaces, classes and types.

A lot of the cgroups and namespaces functionality too time to mature and stabilize.

The network, PID and mount namespaces are the ones unshared, plus a private /proc.

Also with allowing and then disallowing manipulation of certain namespaces (esp the core ones).

Say, without namespaces you would do it like this: function isBig($Number) { return ($Number>1000); } if (isBig(50)) echo '50 is big'; How would this look like when namespaces are used?

Coupled with namespaces you certainly can do this transparently in a multi-user system.

User namespaces actually weren't completely done until late 2013 (Ubuntu didn't have them enabled until 13.10 or 14.04 because it didn't work with XFS).

And you're pointing namespaces but PHP has the exact same problem.

With a Linux kernel local root exploit (which are indeed plentiful), one can escape from a docker container into the initial namespaces of the system.

The "object-orientedness" of C++ really boils down to implicitly passing the this pointer to member functions, inheritance + virtual functions, and namespaces.
