Time to bring back XML namespaces and repurpose them for custom elements

The Linux kernel stole some of its ideas about filesystems and namespaces, such as /proc. But Plan 9’s main legacy is something you use all the time and don’t notice it.

I used Renderware before they bought it and then saw the bones that were left after joining EA. Only thing that remained were some code namespaces and none of the actual rendering lib anymore

It all comes down to:
Namespaces and cgroups. That’s really all you need to know.

does anyone know a good method to deduplicate DWARF type info (because structs get re-encoded per compilation-unit) that takes a trust-but-verify approach (they could indeed differ) to matching by type name (unreliable, anonymous namespaces exist, etc.)

I am the nascent Proxmox user who just discovered namespaces on the Backup Server. We're better able to segregate the backup from difference clusters making our lives just that much easier.

To quote the venerable Tim Peters - "Namespaces are one honking great idea – let's do more of those!"

How do you keep entitlements from multiplying into their own ops headache once agents start composing calls across namespaces?

Maybe science needs to develop a better system for namespaces.

(In my hard sf game setting a running joke is that the IAU AI name assignment system went off the rails sometime in early interstellar colonisation, producing really embarassing naming of many solar systems.)

I really want to do standard ML, and elisp/lazy (a much simpler language), and namespaces, and full prolog, and…

but I should actually release this thing at some point! even without all that stuff, it has a lot of value

Maybe I should build some ontologies for com.atproto and app.bsky namespaces and see where I end up 👀

The exploit chained a bug in the Linux kernel's checksum offload handling to escape. Several people pointed out that Firecracker's jailer—using seccomp and namespaces—is meant to blunt this, but relying on defense-in-depth feels fragile when local privilege escalations keep landing. #linux 2/4

Sobre mudar para c++.

É mais por questão de organização do projeto

namespaces, name mangling e templates.

Evitarei utilizar headers C++.

Write a container runtime and you learn: a container is a host process fenced in by namespaces and cgroups, an image is a folder it chroots into, runc needs a C shim.

Docker's creator turned the HN thread into an AMA.
