(#phld5ba) @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.
(#phld5ba) @movq@www.uninformativ.de Wow! 🤩 That is impressive! 👌 Do you mind sharing how you went about doing this? 🙏
I was able to take a photo of the large sunspots that made the news these days:
https://www.uninformativ.de/pics/photo/astro/2024-05-11–IMG_7512-sun-AR3664.jpg
It’s not a super high quality shot, my scope isn’t good enough for that. Still cool to see. 😎
(#ghroc5q) @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?
(#iefub6q) @movq@www.uninformativ.de Look forward to the results 🤞
(#p7gbjzq) Oh so it really does hit some stupid arbitrary endpoint at AWS 😱
(#2du5cpq) (The old device I’m referring to was a handheld device. It was not built into the car and was not running 24/7.)
(#iefub6q) 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!)
(#iefub6q) @prologic@twtxt.net 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. 🤔
(#iefub6q) @prologic@twtxt.net 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.
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.
Hey @bmallred@staystrong.run 👋 Can you see this? 🤔
I will be deleting 14 inactive and unused accounts (for >3 years) on my Gitea instance git.mills.io at some point over the next few days. One of those accounts is yours @adi@twtxt.net – If you’d like to keep it, I suggest you sign-in 😅
(#iefub6q) 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…
(#iefub6q) @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 🤣
One thing I’ve learned from locking down my Android phone (see #pknsrda):
The data for assisted GPS does not come from Google or, better yet, A PUBLIC SERVICE, but from a server hosted by the hardware manufacturer. Without regularly fetching fresh A-GPS data, the GPS performance is much worse (https://en.wikipedia.org/wiki/Assisted_GNSS).
This means that the hardware manufacturer has (more or less) direct control over whether I’m able to use GPS or not. This isn’t an Android setting, it’s buried deep within the device, no way to change the URL. If that manufacturer decides one day to cut me off, for whatever reason, or goes bankrupt or whatever, then I’ll have to buy a new phone.
And of course, this data transfer is encrypted as well, so I don’t know what my phone sends to those servers.
All this smartphone business is such a clusterfuck. I should have never bought one of those things.
Je cherche de quoi s’isoler du bruit pour me concentrer. C’est pour plusieurs heures, il faut donc que ça soit plus confortable que des boules quies. Des suggestions?

(#dvnigcq) @prologic@twtxt.net Thanks. I expected this to take much longer. 😅
(#dvnigcq) @movq@www.uninformativ.de Welcome back! 🤗
(#dvnigcq) Whoohoo, it’s fixed. 🥳 Now I can look at funny pictures again!
I took the opportunity to remove some dependencies on the internet from my workflow. Actually, outages like these are healthy.
(#dvnigcq) @movq@www.uninformativ.de Haha cya 👋
(#xd77bfq) @mckinley@twtxt.net Yeah pipes and shell pipelines are a powerful and easy to use tool 👌
(#xd77bfq) @prologic@twtxt.net I know, right? It’s a very elegant solution to the problem using standard command line utilities. It was too hard to find. I went through 3 or 4 Stack Exchange threads from my Web search before I found somebody linking to this answer. People were misunderstanding the question and suggesting all kinds of crazy methods including weird, proprietary, GUI Windows software.
(#dvnigcq) This is going to take a while … See ya in a couple of days/weeks.
I have a day off, national holiday.
What happened so far:
I take this as a sign to not do any computer stuff today. 🤣
(#l2uil4a) @prologic@twtxt.net Doesn’t matter. Far, far away! From everything! That’s where I’d go. 😂
(#ixpmzia) Ran a few tests.
Copying data from the NAS’s encrypted ZFS pool to the USB disk’s encrypted btrfs runs at ~20 MByte/s. That is for a single 1 GB file of random data. Cold caches, sync included.
That same USB disk with the same btrfs can sustain ~75 MByte/s when I use it on my workstation (i7-3770).
And indeed, the aes flag does not show up in the output of lscpu on the NAS.
I’ll try to tweak some things about this, but it might be time for an upgrade … 🫤 (Or I’ll have to re-think the entire thing somehow.)
(#ixpmzia) @mckinley@twtxt.net It’s probably a bit faster, but not much. Maybe 20-30 MByte/s (I watched one 40 GB file being copied and it took 20-30 minutes or something like that.)
I need to optimize this. 🥴
(#ixpmzia) The “annoying” thing about hardware these days is that it basically keeps working “forever”. At least much, much longer that you’d expect.
Now that I think about it … I only remember one PC of mine actually dying because of a hardware failure – and that was probably because I did too much overclocking. 😂 If it wasn’t for changes in software, I could probably still use them all. I mean, why not, my Pentium 133 still works and I use it for gaming regularly.
So … my little NAS probably won’t die any time soon. Hmmm.
(#ixpmzia) @mckinley@twtxt.net Not really sure, to be honest. Probably a couple hundred GB … ? 🤔 With the changed data, it might be half a TB to transfer? I’m just guessing.
Let’s see how it goes next time. I don’t expect to add much data any time soon. (On the other hand, I’ll swap the USB disks for the next run, so it’ll take the same ~9 hours, again. Meh.)
I think the solution is to have less data. 😈
(#e24exeq) @lyse@lyse.isobeef.org Yeah, only ~30 of the ~133 feeds I’m following have had a twt in the last month … 56 in the last year. Some had their last twt in 2016. 🫤
(#7gwktxq) @prologic@twtxt.net From the DOM? That can’t be right. 😳😳😳
(#bghmkra) @prologic@twtxt.net It always fetches the canonical feed URL and, when it can’t find the latest twt hash (that it saw in the previous run) it traverses the archived feeds until it does find it. Something along those lines.
I just got one such notification:

Now, your feed did not get archived, as far as I can tell. So why am I getting this then? Have you edited a twt just now? That would explain it. 😅
(#7gwktxq) @prologic@twtxt.net Strip it from what? From requests being sent to the server? That’s always been the case, afaik. 🤔
(#7gwktxq) @prologic@twtxt.net Huh? What does that look like in Chrome? 🤔 (I only have Chromium.)
(#bghmkra) @prologic@twtxt.net My client tells me when it fetches archived feeds. That’s all.

(#2tjsjuq) @prologic@twtxt.net One minor detail: The Makefile wants to run date -Is, which doesn’t exist on OpenBSD. Not sure how relevant this platform is for you, though. 😅
I haven’t come up with a portable solution yet. date '+%FT%T%z' is the closest approximation that works on both GNU and OpenBSD, but it doesn’t include a colon in the time zone offset, so it’s 0200 instead of 02:00. 🤦 I’m not sure if this is ISO8601 compliant. And it’s still not POSIX. 🤦 Well, I tried. 😂
(#2tjsjuq) @prologic@twtxt.net Newcomers might have a little difficulty because just “installing” a Go compiler is not enough – you also need to add ~/go/bin to your $PATH, at least I did. I’m not sure what to do about it, though. 🤔 This doesn’t really belong into Yarn’s setup guide and it’s mentioned as one of the first things in the Arch wiki, for example, but still … To newcomers this might look a bit like a broken build process:
openbsd$ gmake server
/bin/sh: minify: not found
/bin/sh: minify: not found
/bin/sh: minify: not found
gmake: *** [Makefile:84: generate] Error 127
Maybe extend Yarn’s guide just a little bit, like: “… be sure to have Go installed and set up properly, e.g. env vars are set …”? Maybe that could point readers into the right direction. 🤔
(#ixpmzia) What I don’t like about my strategy is that it’s so slow. ☹️ I did change a lot of data this time, so it’s slower than usual, but still …
The backup run from my main workstation onto the NAS took 2.5 hours. The one from my laptop to the NAS took 1.75 hours (hmm, why the difference?). (Those two ran one after the other, not at the same time.)
The backup run from my NAS onto one of the USBs disks is still running, I started it 5.5 hours ago. I hope it’ll finish within the next 2 hours.
Most of this is CPU-bound, because I’m using full disk encryption everywhere and that NAS only has a tiny AMD C-60 CPU from ~2011 which runs at 1 GHz and doesn’t even have a CPU fan. I guess I could upgrade this box, but it’s still working, just slow, so I won’t throw it in the trash – and what do I do with it then? Can’t sell it, can’t gift it to anyone. So I’ll keep using it.

(#2tjsjuq) @prologic@twtxt.net I just set up a Yarn instance from scratch and, honestly, I don’t think a yarnd setup is needed. 🤔
I followed the instructions here and they were simple enough: https://git.mills.io/yarnsocial/yarn/src/branch/main/README.md#configuring-your-pod
It needs a little polishing (for example, it says COOKIE_SECRET is optional which it isn’t), but it was a good experience overall.
Maybe it’s just me, but I prefer reading installation instructions. And I believe that not having something like yarnd setup nudges you (the author) into keeping those instructions short and concise. Whereas the existence of yarnd setup means that you can cram everything and the kitchen sink in there, because it’s convenient. That can lead to a convoluted setup process – and me, the user, does not really know what that command really does, which is something that I, personally, don’t like. 😅

(#pknsrda) I wonder what Android does now that I’ve blocked all those connections. Will it queue all the data and just send it the next time it has an internet connection (which will happen sooner or later)? That would mean my blocking attempts are mostly pointless. 🥴
