@Kerplunk we'd suggest you read the security section at apt.izzysoft.de/fdroid/index/i… 😉 TL;DR: multiple scans are performed on apps published via #IzzyOnDroid, to make it as safe & secure as can be. In the 10 years of our existence, there hasn't been a single incident of a malicious app. So please, don't spread uninformed misinformation ("without checks" even). Thanks! @CoMaps
PS: IzzyOnDroid also has #reproducibleBuilds to ensure apps were built from the indicated source. Planned for CoMaps as well

And you can be affirmed it's the very same FOSS build, as at IzzyOnDroid it is a Reproducible Build – meaning, our builders built the APK from Sylvia's code, and ended up with a byte-by-byte identical APK.
Bonus points: updates usually reach you within 24h of Sylvia making them available. Our build cycles are pretty short: just a few hours, instead of a few days 😉

#ReproducibleBuilds talk at #FOSSY2025 went pretty well today, presented by myself and my colleague Chris Lamb...

W00t, w00t! New NeoStore (one of our F-Droid clients) arrived, now showing the RB status directly next to the versions of each app 🥳
#IzzyOnDroid #reproducibleBuilds
I believe it will be recorded and live streamed ... presuming, of course, no serious intervention by gremlins!
I have not followed closely, but always glad to see all the work done verifying android apps!
#ReproducibleBuilds has definitely grown to span many different types of software, and really it should be helpful everywhere!
will the session be recorded, for those who cannot attend in person? Running multiple RB verification builders for Android apps ourselves (see e.g. android.izzysoft.de/articles/n… and codeberg.org/IzzyOnDroid/rbtlo… plus codeberg.org/bg443/rbtlog / shields.rbtlog.dev/), we're of course interested in what you and Chris have to say 🤗

sorry, but I had to boost this again now. @fdroidorg can you please make optically clear which APKs you reproduced? Developers knock our doors wondering why we say their app is not RB, while you claim it is – and checking, EACH SINGLE TIME we find the app is NOT set up RB at your end, and the JSON at your verification server clearly states you verified YOUR OWN build. Yes, that might show your build is deterministic – but not that theirs is RB. It's confusing.
So I had some more thoughts about FOSS sustainability. I've had them for some time. But this weeks issues reminded me of them.
So here's a mild spruik for some of the orgs who make my digital spaces for myself and my project and also package @librecast
onepict.com/20250628-plussusta…
Speaking of RB:
DavDroid 4.5.1 unfortunately failed RB. Which shows the thin line between "deterministic" and "reproducible":
We were able to build the app umpteen times, and got the very same, byte identical APK on each build: deterministic. So, it was reproducible, right? Well: no. It didn't match the APK built by the developer. A very slight difference in this case, an "off-by-one" in the baseline (so don't you worry, it's just the optimizer).

Btw: kudos for this go to @bg443 – who runs an independent builder (i.e. Ben is not a member of IzzyOnDroid himself, but his builder covers several of our apps. So it's verifying our builders are telling the truth, so to say).
So while IoD takes the APKs directly from the devs, our builders verify they were indeed built from the source code the devs claim to – while independents like Ben verify we're not "cheating". The winners are YOU
Dear developers of #Android #apps which are listed at #IzzyOnDroid and have been confirmed as #reproducibleBuilds by one (or more) of our builders:
