Thanks, it’s late here now but I’ll try to look soon. I didn’t realize significant improvements over Goldberg etc al were really possible. I’ll try to understand that too.

Is there another post somewhere giving a general description of what you are doing?

Do you have a link about your messaging app? And PIR doesn’t conceal the existence of traffic, so it doesn’t seem like the right thing for messaging. It’s more for databases as the name implies. What exactly are you trying to do?

This was basically Blondies Pizza back in the day. Also the nitter thread is from 2019.

I’d say run a local imap server rather than dealing with the weirdness of storage shares across multiple OS’s.

If we told just anyone, it wouldn’t be private!!!

Srsly any phone app is inherently insecure because the phone itself is insecure. And there’s lots of metadata leakage, like the phone broadcasting its location. There is no “go to app”. It all depends on what you are trying to do and who you are trying to communicate with.

If this is for live disks or mirrors (not backup), LUKS is reasonable. Backup is different from mirroring since one of the things it protects you from is accidentally deleting files. If you delete a file from your main drive, it also disappears from the mirror drive, so mirrors are not backup. For encrypted backup, I’ve been using Borg backup which is quite well thought out, though confusing at first. The backups go on a remote server which is ok since they are all encrypted.

Sort by newest first.

There is already a subscribed tab, and I use it most of the time when I want to catch up on selected topics. I use the local or all feed when I want to browse a wider view of what’s going on in general. Right now the total amount of Lemmy traffic is small enough that browsing that way is tolerable, which it wouldn’t be e.g. on reddit.

I do think that the Lemmy software design is more meme-oriented than I’d prefer, because of stuff like the thumbnail pic with every post in the main feeds. The more interesting parts of reddit to me were text-only and we don’t have that here.

I’d like the feed to be adjusted so that if there are a bunch of posts from the same community not too far apart from each other chronologically, to group them all together. Alternatively, a way to block communities showing in your front page view without blocking them completely. It’s not just memes, there are a bunch of other topics that also clutter up the front page constantly. Even things like news reports in Dutch, which are perfectly legit except I can’t read them, would be less annoying with this type of feature.

Wait you mean you don’t cook the oats? Oats (the old fashioned 30 minute kind) cook nicely for me in 4 minutes in an instant pot, but no cooking sounds even better.

As I understand it, the interest income is tax deferred while it is still in the IRA. So over a long period it can appreciate a lot more than if taxes were being taken out every year.

Dang, FSF shop temporarily closed. https://shop.fsf.org/

Well what phone is it? There are tons of music playing programs on f-droid. Why not just run one? I’ve been using Vanilla Music. I don’t like it that much, but don’t feel like derping around trying more and more of them. Vanilla is better than some others that I tried.

If you can manage programmers, then yes. Everyone says that’s just like herding cats.

The PFS comes from deleting the secret DH parameters after you are done using them.

The codecs are built into the client (I’m using linphone) and they all sound like crap. Provider is vitelity.net but I have a twilio account so could try that. Also, they only work at all when the phone is online by wifi. Using the phone’s mobile data is total fail. Too many dropouts etc.

This forwards to an (oh the irony) blogspot post, https://articlesgallery8543.blogspot.com/2023/10/lets-decentralize-web-together.html It encourages people to move off sites like facebook towards sites like lemmy. Great but I think we knew that already.

Voip call quality is terrible, it is near unusable over mobile data IME, it adds latency etc.

I guess an intermediate measure might be to make all your phone calls through a forwarding proxy (e.g. implemented with Twilio API) so that all the mobile carrier sees is that your phone calls all go to the same number. Similarly you’d give out a VOIP DID number that forwards to your mobile, so all your incoming calls would appear to come from the same number.

Don’t know about Signal but the way PFS usually works is there is something like a Diffie-Hellman (DH) key exchange. Each person generates a random (private) number, remembers it, crunches it mathematically into a public number, and sends the public number to the other person. Each then combines their private number with the public number that they got from the other person, and this (because of how DH works) cleverly gives both people the same secret number they use for the encryption, but the secret can’t be reconstructed without knowing at least one of the private numbers. Finally, the PFS part is simply that each person permanently deletes both the shared secret and the private number they generated for that exchange (they will create new ones next time they want to communicate). That means there is no way to reconstruct the secret and re-decrypt the message.

Of course, authentication also has to be added to all this.

For more info, probably easiest to look up Diffie-Hellman key exchange online.
