Hey @ruud@mastodon.world - welcome amongst the ​s of the world!

Thanks for your ping about the installation in 🇳🇱 Netherlands.

I added you to the list of known instances on the wiki and sent you a federation request.

addressing a passerby: Uh, hey, nice to meet you! You're running a flohmarkt as well? You'd like to have some more visibility and reach? Come on - let's federate!

flohmarkt instances Codeberg.org

Hey ! I just installed the new package 0.12.1~ynh3.

The flohmarkt code stays the same. @grindhold@23.social researched the issue that after upgrades to flohmarkt the clients needed to force reload the frontend.

To circumvent the problem nginx now adds a header to control caching. **Thanks for the PR to the yunohost integration repo by @grindhold@23.social!

The testing environment of found an issue with using add_header in nested nginx-configurations and delivered a reference: https://www.peterbe.com/plog/be-very-careful-with-your-add_header-in-nginx

Thanks to the great work of all the yunohost contributers for that great testing environment!

The newer package can be updated or installed from the yunohost app store.

From the download counter on the release page at codeberg I estimated that there are between 30 and 40 instances out there running on .

(Who uses ZIP 😉 ? Well, the yunohost integration does and the counter went up by the numbers shortly after publishing the latest update to the yunohost app integration.)

On the wiki we have a list of ~20 flohmarkts. The list is meant for users to choose an instance and for admins to look for other flohmarkts to federate with.

I'd like to invite everybody to drop us a line to add your flohmarkt to the wiki: either as a codeberg issue or as a fedimessage or fedipost or on IRC.

And even if you'd not like to be on the wiki page: federate with others to make your small ads more visible.

enables that ​s show up on the other instances an instance is federated with directly. This gives every small ad some more reach.

My impression is that federation is extremly important to make the flohmarkts more successful as an alternative to the well know centralized services.

I opened an issue to discuss how to make federating easier without forcing anyone to share more data with the world than they do with the actual version of flohmarkt.

After an outage of (caused by a problem at ) @Mer__edith@mastodon.world argued that a cloud provider is needed to run a service like Signal.

I answered that a cloud provider is needed, because Signal doesn't federate (and thereby build its own so called 'cloud').

I added that I doubt that by using a cloud provider Signal doesn't leak the social graph of their accounts.

I got referred to the by @newhinton@troet.cafe designed to protect the social graph which I simplified to hashing leaving out the use of part in my post.

I stated that I wouldn't understand how one could be sure that all which is guaranteed by using SGX really is like it is promised.

The only answer by @moehrenfeld@social.karotte.org is that I indeed didn't understand "Private Contact Discovery" completely.

It's frustrating to doubt and being left in the dark about the facts.

Today I learned something new: SGX is not meant to be save against physical attacks - or to phrase it different: SGX is meant to protect data if the OS is completely compromised, but the server is under physical safety and control:

…All three chipmakers exclude physical attacks from threat models for their TEEs, also known as secure enclaves.… (Nvidia, AMD, Intel)

…“These features keep getting broken, but that doesn’t stop vendors from selling them for these use cases—and people keep believing them and spending time using them,”…

…Those making these statements run the gamut from cloud providers to AI engines, blockchain platforms, and even the chipmakers themselves. Here are some examples:…

…The maker of the Signal private messenger assures users that its use of SGX means that “keys associated with this encryption never leave the underlying CPU, so they’re not accessible to the server owners or anyone else with access to server infrastructure.” Signal has long relied on SGX to protect contact-discovery data.…

Big thanks to @kyle@kylerank.in for sharing this post by by @arstechnica@mastodon.social: https://arstechnica.com/security/2025/10/new-physical-attacks-are-quickly-diluting-secure-enclave-defenses-from-nvidia-amd-and-intel/ !

Maybe my naïve assumption that you can only protect data on hardware you physical own and protect has not been so wrong at all.

I'd be happy to read arguments and opinions and corrections to the arstechnica article.
