You can let agent churn unattended if you have some sort of known goal. Write a test that should not pass and then tell the agent to come up with something that passes the test without changing the test itself.

For this kind of fuzzing llms are not bad.

Wouldnt that be stackless (shared stack)

You are not wrong and this is indeed what zig is trying to push by making all std functions that allocate take a allocator parameter.

Trusted computing isn't about security. Its about vendors not trusting you.

Why haven't prebuilt PC market been doing this to hide the fact they are using a single RAM stick?

I see. I can not give more insightful answer here then. From personal experience, I've noticed with 0.16 with the std.Io async stuff that you cannot do:

   io.concurrent(foo, .{});

where foo's return type is `error{foobar}!noreturn`, because the compiler crashes when it tries to use that type as a std.Io.Future(T)'s struct field. Might be related or not.

I think rust calls them "zero sized types".

Indeed what was referred to here is the zig build system cache.

AFAIK garbage collection is basically not implemented yet. I myself do `ZIG_LOCAL_CACHE_DIR=~/.cache/zig` so I only have to nuke single directory whenever I feel like it.

0.16 is the development version. 0.15.2 is latest release.

The language itself does not change much, but the std does. It depends on individuals, but some people rely less on the std, some copy the old code that they still need.

> Are there cases where packages you may use fall behind the language?

Using third party packages is quite problematic yes. I don't recommend using them too much personally, unless you want to make more work for yourself.

I feel safe when claude outputs dd commands that wipe your drive to benchmark disk write speed :)

You can enable error traces for release-fast builds as well, without enabling full debug info. Though the quality of call stack of course vary depending on optimization level.

Note that this "diagnostics" pattern is only meant for handling a error locally with potential extra information, or showing a more useful error to a end user of the software. For software bugs, crashes, or developer facing errors, you often don't have to do anything as zig has pretty good error traces by default.

I dont think the core team accepts LLM generated code in the std.

I like that zig takes freestanding target seriously. And seems like 0.16 becomes even better for freestanding code reusability.

Cloudef — Fri, 13 Feb 2026 00:49:37 +0000

Its not the GC, its that D has no direction. Its kitchen sink of features and the optionality just fragments the ecosystem (betterC, gc) etc, making reusing code hard.
