The other key limitation of PowerShell is that its commands all run in the same process (e.g. PowerShell is akin to a REPL). By contrast, UNIX programs each run in their own process, giving the programmer a much greater degree of freedom i

OverlayFS’s speedup comes in part “by allowing the kernel to include only a single copy of a file read from multiple containers in it’s page cache.” I’m concerned that this could be a source of information leaks across containers. Suppose c

"Real-time guarantee" in the context of consistency models (i.e. this article) means something completely different from "real-time guarantee" in the context of operating systems.

What mystifies me in these systemd discussions is that systemd proponents always seem to think that "modular" is somehow the opposite of "monolithic," when it is entirely possible for a system to be both. "Modular&q

Somehow you think I'm talking about systemd and init scripts and the things they do. I'm not. The original question I replied to was about why pipes (or any OS-level IPC) shouldn't try to solve application-level problems. M

If duplicate code bothers you this much, then what stops you from abstracting the common routines into something like BSD's /etc/rc.subr, and then sourcing them in the service-specific init script?

Compatibility isn't the problem. The problem is the use of structured binary data itself for logs. Logging binary structures instead of raw text makes it very difficult to recover from crashes or misbehavior, since the logging faci

I'm not sure that your example prevents the implementation of per-tab javascript VMs. Wouldn't the browser be designed such that its kernel mediated all tab-to-tab runtime state queries? Then, tabs wouldn't directly access

Sure, tabs can load static assets from a read-only cache instead of re-fetching everything from the origin (be it an in-browser cache run by the browser kernel, or a Web cache somewhere between you and the origin). But surely, the tabs run

Depending on how it's implemented, there's no real reason why it couldn't be done. For example, I could create SceneGraph_fs, which exposed the scene graph of objects as a directory hierarchy. The filesystem's toplevel
