Wow, I can’t even tell you how many times I’ve needed to compress a Dolby Vision videos in a pinch. Like, how have I been living my life all these years just sending uncompressed Dolby Vision videos around? It’s unthinkable

I have no idea what a Dolby vision video is. I’m so glad I moved to SimpleX

They are going to introduce chat bots and gambling before they do non phone number identities.

For those not in the know, it’s dolby’s proprietary hdr format, in a similiar vein to their atmos product, which is high definition audio. You see it labeled in linux isos as “DV”, and if it doesn’t also have the HDR label there’s a good chance your video is going to have the wrong colors in it.

That’s why you get copies that support both DV and normal HDR.

why do those videos look green/off-color? Is there any way to view them properly?

Now do location sharing…

But it already has the ability to share your location, or am I missing what you’re requesting? Right now if you go into a chat, click the + sign, there’s an option to share your location.

That just sends a screenshot on a map and a Google maps link. What we want is realtime location sharing

I’m torn on it. I love that everything is geared towards privacy, but location sharing seems to go against the grain of the program’s principles.

I’d make use of it if it was included, but I understand why it doesn’t and Google Maps does a similar thing.

Location showing only goes against privacy If it’s not done right.

It’s expensive to encrypt it and forward it through the servers or proxies, but revealing if done peer to peer. (And less reliable)

But by the time I’m giving “live location” I don’t think my ip address is THAT private 😝

How is location expensive to encrypt? I share my location all the time but to do that I have to write an entire sentence to other people where I am. Just introduce a new message type (like with edits) frontend to enable location sharing. Location is sent every 5min or if the other person requests an update, than location is updated again (send location update request message to trigger response on the other side). Same encryption as everything else and easy to implement. Of course the devil is in the detail but the basis are trivial.

The “hardest” part would be to show the location on a map without leaking data but just add a warning dialog and open externally. Every link in Signal you press has the same privacy issues.

It’s very useful when coordinating with people, meeting them, etc

Oh I totally get why it’s useful, but it seems sharing more than intended goes against the privacy-focussed principle of the app.

Though I do now see that if done correctly, it could be a bonus.

I’ve been hoping for it for a while. I really need to use it from time to time. Now I have to use WhatsApp or Messenger for it which is just bleugh.

Given how much normal messaging already costs them, i don’t think this is in their budget. And i say that as a monthly donator.

So even if they introduce it, it would probably have to be behind some paywall.

if we assume location sharing = latitude + longitude + unix timestamp + a ~10 minute update interval + sane defaults [0], it shouldn’t be too straining of a resource. At least I don’t imaging it would be. It’s basically the “data” required to store the following as a message, “48.858370,2.294481,1707360628” with maybe a special header that indicates it’s location sharing data. We’re talking less than 340 kilobytes to store/process 10,000 messages. Even if it updated every minute, you’re only sending 1,440 “location sharing” messages per day IF you’ve even set it to share updates for 24 hours.

Scale this to millions of people and it’s just a blip in the radar, considering its not enabled by default, turns off after some time. Heck, they could even have the client only send updates if your location has changed significantly. If you’re sharing location but your position hasn’t changed since last message sent, it could increase the time before it sends an update to further minimize the impact. Just my 2 cents.

I do agree its probably pretty low on their to-do list. Would be nice to have tho. Monthly donor here too, super happy with the app.

[0] With the assumption that it can only be enabled with some timer to auto-disable.
