In-reply-to » Hey @bmallred 👋 Can you see this? 🤔

The weird this is I still see your profile as

bmallred may not follow you

I assume you share your followings publicly, I see them on your feed, so I assume so. I was going to debug this on my side too today to see if.I goofed something up but my pod is rather busy so I hadn’t done that yet 😅 (actually working again finally on search)

In-reply-to » I was able to take a photo of the large sunspots that made the news these days:

@prologic@twtxt.net Thanks 😅

This is my setup, I think I posted these before:

It’s a Celestron Ultima 100 (originally bought for bird watching, not a telescope) with a special adapter so that I can mount my Canon EOS 600D directly. The sun filter is just a generic filter for 100mm scopes. The tripod isn’t very good and actually rather annoying. 😂

It’s not a very complicated setup. 🤔 Being able to mount the camera directly is crucial.

In-reply-to » Another thing that doesn’t work anymore after blocking network traffic from my Android phone: Some push notifications.

@aelaraji@aelaraji.com It would appear so. 🤔 (I’m too lazy to set that up, though, I rather just don’t use notifications. They’re not that important in this case.)

I was not aware that I needed a cloud service for something as (seemingly) simple as local app notifications. 😳

Another thing that doesn’t work anymore after blocking network traffic from my Android phone: Some push notifications.

I run a Matrix server for our family. I use “FluffyChat” on my phone. Traffic from the phone to my Matrix server is allowed and chatting in FluffyChat works.

But I don’t get any notifications anymore on new messages.

So, what’s going on here? Does FluffyChat, which only really needs to talk to my own server, rely on some cloud service for notifications? Seriously? 🤔 How does that work, does this cloud service see all my notifications or what?

Anyone around who did app development on Android? Can you shed some light on this?

In-reply-to » @prologic Regarding the static URL: The hostname at least is a CNAME record and resolves to something at cloudfront. What I meant was that I, as a user, cannot configure this URL anywhere in the Android UI. 🤔

Oh so it really does hit some stupid arbitrary endpoint at AWS 😱

In-reply-to » @prologic Hmm, have you used a GPS device 15, 20 years ago? I had one in my car. It would take a long time until it got a first “fix” of your location. That’s because it can take up to 12 minutes until you have gathered all the data directly from the satellites. These days, GPS trackers on smartphones get a fix within seconds, maybe 30 seconds tops, because they get pre-seeded with (approximated) satellite positions via A-GPS.

(The old device I’m referring to was a handheld device. It was not built into the car and was not running 24/7.)

In-reply-to » One thing I’ve learned from locking down my Android phone (see #pknsrda):

I’ll make an experiment: I’ll keep blocking all the phone’s internet traffic and then we’ll see how bad the GPS performance will get in a couple of hours/days. 😅 (If I got it all wrong and it still works fine, that’d be great!)

These days, GPS trackers on smartphones get a fix within seconds, maybe 30 seconds tops, because they get pre-seeded with (approximated) satellite positions via A-GPS.

We also not only have the USA’s GPS these days but also other satellite systems like the EU’s Galileo or Russia’s Glonass. A-GPS helps you get “in contact” quickly with more satellites, which enhances the precision quite a lot.

So, yeah, you can use it without A-GPS. But it would be very annoying and imprecise. I bought a new phone last year and A-GPS was broken on that one (I saw no internet traffic at all), which made it basically useless, to the point where I wouldn’t want to use it at all. I sent it back and bought another model.

To my knowledge, the only way to use GPS without something like A-GPS is to have it turned on all the time, so you get regular updates directly from the satellites.

I can’t imagine it’s a static URL either, it surely has to be a unicast address of some sort. Relying on a static URL sounds like an utter disaster to me 🤔 I’d have to read the open spec on this…

@movq@www.uninformativ.de Surely it isn’t as bad as this though right? 🤔 I mean reading the Wikipedia page on A-GPS, it sounds to me like it sends enough data to the nearest tower to give you enough data to warm-up the GPS receivership, presumably with GPS coordinates of the tower itself? I can imagine this data payload would include the Date/Time, IEMI and possibly your SIM details and Phone number (why not). It could be worse 🤣
