In the mid-2000ds, there eventually came a time when the xlock (Ex-lock) screen locker disappeared from the last university workstations that still had it. People routinely got puzzled when they could not run it. It was a fun prank to tell

I'm puzzled. It is a good thing that this works with empty makefiles, and it has probably worked from quite early on. :)

Subscribed. I like this explorative approach.

Not using a template language and avoiding to do error handling are not good ways to make a program "simple and easy to understand". If your users run into one of the many string escaping bugs or get an unexpected error code from

Git over SSH to the Raspberry Pi. You do not need a "hosted" git environment to keep a repo in a central location; a simple Unix account is enough.

I guess the TL;DR is: This is a cool project, don't get me wrong :) I just feel that it's difficult to do in Linux's heterogeneous environment where everyone uses their own kernel configuration and libc variant... the reason

eBPF was the initial proposal, but Landlock didn't go with it in the end. It's just using a set of regular system calls, the logic behind it is just implemented in C in the kernel as a LSM.

Sorry, my English... :) I meant "Unlike namespaces", not "Other than namespaces" -- Landlock does not use namespaces.

+1, escalating privileges in order to drop privileges is counterintuitive and risky. This was the best possible solution for a while, but things are getting better with Landlock introducing unprivileged sandboxing for file accesses. There a

I hope so too :) There are libraries at https://github.com/landlock-lsm to simplify that, I'm using these productively for a few months. (In fact, I'm sending this from a landlocked web browser. :)) This also ties

The general excitement about generics on this thread makes me uneasy. Please keep in mind that generics are a pretty big hammer - they can add a lot of complication if not used with caution. Only use a language feature if you absolutely mus

Passing null instead of empty collections is a practice that should be discouraged imho. There is an entire design pattern ("Null object" [1]) that's making the point that you should use a "neutral" object instead.
