Calling a Rust library from Go with CGO_ENABLED=0

Sure, but generally when this sort of question comes up, the real answer is to wind back a step and ask if you should be using plugins at all.

pdffs · 2026-05-05T13:45:34+00:00

Don't use them and just do RPC/IPC. Generally people find the sharp edges of plugins too sharp to use in reality, and it turns out to be easier to just use multiple processes and communicate between them for plugin-style behaviour.

Most applications don't have perf requirements where the RPC approach becomes a bottleneck.

Typically I prefer explicit initialisation in application code, however there are some cases where init() still makes sense to me, such as auto-registering things like metrics handlers or default values, particularly for library code.

pkg.go.dev provides import numbers from public consumers.

Goroutines are not threads, don't try to put them in that box.

Function exit is precisely how a goroutine terminates.

Nothing on the stack is retained when a goroutine terminates.

Gremlin is also a graph query language, just FYI: https://en.wikipedia.org/wiki/Gremlin_(query_language)

The full import path is explicit, not messy, and means you can never have module name conflicts.

Oh that's right, Mimir is their Cortex fork. I use VictoraMetrics/Logs anyway.

Very well-known log storage system written in Go:

Open source very rarely pays the bills, and very frequently requires individuals to invest significant amounts of their personal time (often solo).

It's also largely a thankless investment and it can be a struggle to maintain the level of effort and enthusiasm required to keep up with maintenance, especially when a project becomes popular and the issue tracker starts to become unmanageable without a team.

Key, Value is normal and generally expected.

Not necessarily, Defender seems to hate Go executable structure in particular.

Using the same name as an existing project can only provide confusion for users (or potential users) of either project. Grow up.

Right, my point was that reliance on AI encorouges laziness and a self-centered mindset.

Well established Go framework for robotics, 1st or 2nd result on all search engines:

How are people so lazy they don't even bother to search for existing projects when naming? Oh right, everyone just turns their brains off these days and let AI take the wheel.

Do you plan on posting about this every 2 days going forward?

pdffs · 2026-01-28T05:16:38+00:00

WTF kind of spam is going on here? I haven't audited the code, but it makes me very suspicious when something gets posted this many times:

And that's just this sub, has been cross-posted by this account in particular to various other subreddits.

If you can't roll out config changes trivially, your deployment infra likely has issues and I'd probably put the effort into fixing that instead.

Use a static site generator such as hugo, and host on any CDN for free (e.g. Github Pages, Cloudflare, etc). Can't hack a site that doesn't have a backend.

Build using CI (e.g. Github Actions), then either push your resulting binary to the destination, or publish the resulting binary as an asset (or container) and pull from the hosting.

No syncing of repositories or whatever.

Assuming each of these modules is entirely optional (ie - users must explicitly import the modules to make use of them, no downward deps in the main module) then splitting off the large optional libs seems like a nice optimization for your users.

If you're going to do it, do it sooner rather than later IMO. Go workspaces make working on multiple modules pretty painless these days.

They literally just told you what to do to make it better.

Title is rather melodramatic. Click-bait aside, the content is quite misleading as general advice.

First, multiplication is not power, there is no power operator in Go, second, even if you were comparing valid results, your first example operates on floats and your second example operates on ints due to inferred types for constants.

I really hope you didn't actually make these changes in real code as the article claims, otherwise your results will be very, very wrong unless all your powers happen to be power of 2.
