Welcome to the RB family, Sav PDF Viewer 🥳

https://apt.izzysoft.de/packages/com.saverio.pdfviewer

Sav PDF Viewer Pro is a simple PDF viewer that lets you easily view PDF files. It automatically saves the last position for each file, lets you place bookmarks, and more – without requiring a single permission.

With some help by its developer, it finally is RB now

Correct #FDroid guarantees that their app builds correspond to the publicly available source code. Fore some apps it's just a promise, but when the app developers support #ReproducibleBuilds it's also possible to verify this promise. https://reproducible-builds.org/

Reproducible Builds — a set of software development practices that create an independently-verifiable path from source to binary code

For the #NixOS #QubesOS and #reproduciblebuilds nerds out there, I finally found some time to clean this up enough for post my fully-reproducible NixOS template for QubesOS PR: https://github.com/evq/qubes-nixos-template/pull/7

This feels so niche it kind of hurts my soul. FWIW I'll do a lightning talk on the value of build reproducibility on Thursday, so maybe I can get a few more people to care.

For those who use #NeoStore, one of our recommended clients, we have exciting news: they just added a setting that puts you in control of #ReproducibleBuilds.

Settings › Service › Disable auto-update on non-reproducible updates

If you want your RB apps only auto-updated if the update was also confirmed to fully match the source code, consider turning it on for extra security.

You can then still manually update it, regardless of reproducibility status.

Do note …

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."

A nice write-up by @andrewnez on git remote helpers 👉 https://nesbitt.io/2026/03/18/git-remote-helpers.html

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