Fuzzing software becomes much more effective if you can generate _valid_ inputs. We have now built the first approach to _statically_ extract complete and precise input grammars from parser code, producing syntactically valid and diverse inputs by construction. Enjoy!

We've hinted before how the #EU #DMA discussions take place, anyone can see them on video from home, but it's a different thing to be able to roam there.
#FDroid's @eighthave was on the floor and brings us the lowdown.
You'll laugh, you'll cry, you'll say "lawyers!!!", but don't turn your eyes away, this is how the sausage is made, raw, straight from the pipe: https://f-droid.org/2025/09/18/ec-dma-compliance-workshops.html
Don't forget to submit the DMA form! 😄
/PS: Yes, the subtitles grow as you read, we're making a point here!
🇪🇺 The @EUCommission has launched a Call for Evidence on its future European Open Digital Ecosystem Strategy.
This will define how open source and open digital assets support:
🔹 EU tech sovereignty & security
🔹 Competitive, interoperable digital ecosystems
🔹 Sustainable open source communities & businesses
🗓 Open until 3 Feb 2026
👥 Developers, SMEs, public sector, researchers & civil society are invited to contribute.
Have you say: https://ec.europa.eu/info/law/better-regulation/have-your-say/initiatives/16213-European-Open-Digital-Ecosystems_en
@Viss that's the kind of thing, if i were using that, that i'd put in .git/exclude
.gitignore is for things that can be expected to be present, but shouldn't be checked out, .git/exclude is anything specific to your tools
One thing I assume will be a sizable annoyance: is that E2EE won't be possible across the bridge, unless both sides adopt a mutual E2EE protocol. Thus it might be the first case to see a push for experimental implementation of MLS (from MIMI), or otherwise bring some Olm/Megolm compatibility to XMPP, or OMEMO compatibility to Matrix, as I don't know if those can be 1:1 translated back-and-forth. Or just less-sophisticated things like PGP over instant messaging (like PGP over XMPP as transparently facilitated by plugins).
They're both key ratcheting systems, I just don't know how much Olm/Megolm differs from OMEMO.
But at least it bridges the communication gap to be able to start reaching people on another sizable federated instant messaging network.
Frequently Asked Questions about FHE
https://www.jeremykun.com/frequently-asked-questions-about-fhe/
I work on homomorphic encryption (HE or FHE for “fully” homomorphic encryption) and I have written a lot about it on this blog (see the relevant tag). This article is a collection of short answers to questions I see on various threads and news aggregators discussing FHE. Facts If a service uses FHE and can respond to encrypted queries, can’t the service see your query? How is it possible to operate on encrypted data without seeing it?
