You often see us reporting our RB status, and might wonder what's so important about #ReproducibleBuilds – want a recent example? Take a look at https://web.archive.org/web/20260402133949/https://github.com/Nekogram/Nekogram/issues/336 – and the POC at https://github.com/RomashkaTea/nekogram-proof-of-logging

In short: Release APK was built from different code, including a logger to catch all phone numbers contacted. Oh, and the dev thinks that's fine (https://t.me/NekoUpdates/531).

RB would have failed for that app, and shown the diff.

Stay safe out there!

New guide on getnix.io — "What is Nix?"

A beginner-friendly intro to what Nix actually is, how it differs from Docker/Homebrew/Apt/Ansible, and the core concepts you need before diving in. If you've ever wondered why people keep talking about Nix, this one's for you.

What is Nix?

A practical introduction to Nix — what it does, why it exists, and the core concepts you need before diving into real projects.

What's if you could ~$ git clone SWHID?

"You’d end up with git clone as a content-addressed fetch primitive rather than just a URL fetch, which is an interesting building block for reproducible builds and supply chain verification."

Git Remote Helpers

Git can talk to anything if you write the right helper.

I appreciate all the technicalities surrounding it but it would be great if ccache had a mode where it could ensure that the objects that came out of it were binary identical with ones that didn't use ccache from a #ReproducibleBuilds perspective ...
I wonder if such a thing is feasible ...

(2/2) those included 22 #ReproducibleBuilds – of which 6 failed:

* 3 because of not adhering to the "first basic rule": to build the APK from the tagged commit 🙈
* 2 because of failed libraryStripping (so we needed to find the matching NDK and install that for them
* 1 not yet fixed as we could not yet figure the cause

Repairs took me 3+ hours. Easily avoidable. Dear devs, please see our RB hints 4 you, and help us saving time for other important tasks:

Debugging Reproducibility Issues in Rust Software

There is a fun footgun related to compile-time code generation using procedural macros in Rust: if the macro has non-deterministic behavior, then the build process of any crate using it is not reproducible.

Here's a little write-up explaining how I uncovered such an issue in the hashify crate while trying to package Rust software for Guix: https://notes.8pit.net/notes/iqfs.html
