Welcome to the RB family, QRServ

https://apt.izzysoft.de/packages/dev.uint.qrserv

QRServ takes any selected file on your device and makes it available through its own HTTP server at an unused port number. The selected file can then be downloaded via web browser on another device or software that allows file downloads over HTTP from QR codes.

This was made possible thanks to the efforts by its author – and thanks to his SteamDeck running our RB framework

IzzyOnDroid got mentioned in the reproducible-builds.org blog for the April report with a huge block of multiple paragraphs

https://reproducible-builds.org/reports/2025-04/#distribution-roundup

Yes, our RB-framework is available for everyone to use. And today, we even got the first report of an installation running on a Steam Deck

We have no new apps to report today (well, 10 updated apps is also good, right?) – but reached round numbers with our RBs once more:

590 apps (45%) of the #android #apps at the #IzzyOnDroid repo are now #reproducibleBuilds

So sad to hear #OSUOSL is in a bit of a pinch...

They support so many free software projects that I work on, including #Debian and #ReproducibleBuilds and probably several more I did not even realize!

Please support those that support so many others if you can and spread the word!

Congrats to @luj and @Zimm_i48, for the ACM SIGSOFT Distinguished Paper #award at #MSR2025, for our joint paper «Does Functional Package Management Enable #ReproducibleBuilds at Scale? Yes.»

Details, including link to an #openaccess preprint, at: https://2025.msrconf.org/details/msr-2025-technical-papers/32/Does-Functional-Package-Management-Enable-Reproducible-Builds-at-Scale-Yes-

The paper is going to be presented this afternoon at the conf here in Ottawa.

Meanwhile, Gilmore makes an analogy between “reproducible builds” and “pure functions”:
https://lists.reproducible-builds.org/pipermail/rb-general/2025-April/003736.html

It sure feels like a déjà vu to the Nix and Guix folks but it’s good to see it brought up from a different perspective.

Impatient to get a #Backport of #Dino 0.5 for #Debian #Bookworm
... but the build logs were already published, including the hashes of all the binaries, I went ahead and performed a #ReproducibleBuilds check of locally built packages for amd64, arm64 and the "all" architecture... and came up with bit-for-bit identical results!

https://people.debian.org/~vagrant/dino-im-reproduced/

By the time you read this, identical binaries may already land on the Debian archive. I have a newer dino installed now! Try for yourself!

Welcome to the RB family, MSM

https://apt.izzysoft.de/packages/com.prinzpiuz.msm

MSM works as wrapper around your Media server (emby, jellyfin, kodi, plex) and helps you to manage your media files.

Thanks to the help from its developer, starting with v1.9.0 the app is now reproducible

You're interested in Reproducible Builds for Android apps? We've just updated our Wiki on those:

https://gitlab.com/IzzyOnDroid/repo/-/wikis/Reproducible-Builds/

There are new pages for setting up build recipes, and debugging/fixing RBs – which should help you when running your own builder. Which you btw can set up on your Linux machine within 5 minutes using the scripts provided at https://codeberg.org/IzzyOnDroid/rbuilder_setup

Developers also find pages there on making/keeping their apps RB.

Welcome to the RB family, Inure

https://github.com/Hamza417/Inure

Inure is a powerful open source applications manager and analyzer with a good-looking & easy to use interface.

Joint efforts from 3 parties at work here. Most work was done by the developer (thank you, Hamza!) F-Droid devs joined in, and IzzyOnDroid's new builder tools finally brought in the victory on the developer's side. With the next sync, Inure will be available at IoD and F-Droid as RB

Cheers

"Over the last few releases, we changed our build infrastructure to make package builds reproducible. This is enough to reach 90%. The remaining issues need to be fixed in individual packages. After this Change, package builds are expected to be reproducible. Bugs will be filed against packages when an irreproducibility is detected. The goal is to have no fewer than 99% of package builds reproducible."
