18M I like computers, trains, space, radio-related everything and a bunch of other tech related stuff. User of GNU+Linux.
I am also dumb and worthless.
My laptop is HP 255 G7 running Manjaro and Linux Mint.
I own RTL-SDRv3 and RSP1 clone.

user224,

Using a software defined radio (SDR). However you would need additional hardware. The most popular one, RTL-SDR works well with Android apps. There’s a lot you can do with SDRs. With my phone I mostly use it for receiving satellite imagery from the NOAA-15, 18 and 19 which transmit APT around 137MHz making it easy to receive with a simple V-Dipole antenna. Recently Meteor M N2-3 has launched which also transmits LRPT shich is digital at 4 times the resolution. Unfortunately, its LRPT antenna has not deployed properly so the signal is very poor. Ideally I’d use a Yagi-Uda antenna for that. For decoding LRPT, I use SatDump, for APT I record it as audio in SDR++, then use noaa-apt in Termux, but SatDump can decode it too.

I also use it for receiving DAB+ radio with welle.io. A separate DAB+ receiver would cost me just as much as the RTL-SDRv3 + Dipole kit.

ADS-B is also fun to look at.

Anyway, there’s a lot to do with it ranging from just listening to FM radio, up to (illegally) decrypting GSM phone calls and SMS texts. Crazy Danish Hacker has a series on the latter: youtube.com/playlist?list=PLRovDyowOn5F_TFotx0n8A… but that you can’t do on a phone anymore.

user224,

For anyone wondering why they still see the post, there’s currently an issue with post deletions on Lemmy: [Bug]: Lemmy 0.18.2 instances are not federating deletion of a post by user who created post #3588

By selecting “Delete” OP deleted the post only from lemmy.world, his home instance, and lost access to the post. He cannot see this post nor further respond to it.

I had the same issue this morning, which is how I know about it.

I didn’t mention Memmy.

Dobré ráno :)

user224,

Who gets these ideas for stock images? There’s a stock image for everything (legal), I swear.

user224,

During the day my internet speed fluctuates between 0.2-2Mbps so I get that all the time. Though at night and early morning I can get up to 30Mbps. Currently it’s 5:55AM so I am still getting 17Mbps.

user224,

You search for some rare issue 😐
You find a thread that might solve it 🙂
The person has exact same issue (just for a different reason) 😀
There’s an accepted answer 😃
“You don’t need to do it this way” 😭

user224,

Aaah, I am idiot. It’s memes! I never clicked on those links before, xkcd sounds like a porn site xD.

user224,

You can also embed the image

user224,

I am neither. Just an idiot trying to understand stuff.

user224,

4 ears? I wonder how that works. I guess maybe in pairs. Top ears - primary, bottom ears - auxiliary. The top ears could be directional with higher gain to better hear specific sounds and pin-point their direction while bottom pair would work as regular mostly omnidirectional ears to hear everything normally. Another, smaller advantage, could be listening to music. She could have earphones in her auxiliary ears yet still listen with primary ears, though only with directional bias. But wait! Those primary ears are cat ears. Cats can hear sounds up to 64kHz while humans only up to 20kHz. How would that affect music listening experience? Stuff above 20kHz doesn’t matter for listening, because we can’t hear it, but she could. Is there much to hear? If so it would make her listening experience on auxiliary ears quite worse. But obviously it wouldn’t matter if the source is something like MP3 which cuts off at 20.5kHz (in case of 320kbps). Although it still could make a difference, even though we can hear the higher frequencies, our ears have lower sensitivity at those frequencies. So maybe she would still get a better experience on cat ears, right? Most electronic audio sources could sound terrible for her. So there’s a pretty good chace she’d end up being an audiophile. She definitely could hear the difference.

But I am also assuming she’s not deaf, which is also possible.

Ok, I might be overthinking this, it looks good.

It’s bean o’clock

user224,

How many? I have some too, but not many, just 800.

user224,

“AC instructions” xD

user224,

Rather the latter. Forced updates would potentially be low quality while increasing the price of devices. There are many devices from small brands which are very cheap and get no updates. For example, I think it was in 2016 when I got Lark Cumulus 5HD for €50. The specs were fairly good, and while it never got any updates, the OS wasn’t laggy at all. I don’t think I’ve ever seen it lag or freeze. So far the best phone smartphone I had, ironically also the cheapest.

user224,

Test comment. I was unable to reply to someone else. I’ll delete it.

user224,

I miss replaceable batteries, but not just for sustainability. Having a spare battery with you is much, much, much,… better than carrying a power bank + cable with you, which also can’t give your phone juice instantly. Also sometimes the batteries may randomly become universal, like the Nokia BL-5C currently used in many radio receivers.

user224,

hating Android

Have you tried custom ROMs? Android is open-source project with bad shade thanks to phone manufacturers customizing it in their ways. Although in my opinion the last true Android experience was with Android 7. Since then there’s been many features that got locked/removed breaking large amount of apps for security.

user224,

My concern is rather from technical aspect. For example the admins of my home instance temporarily defederated lemmy.world in the past due to having way too high traffic overloading the lemmy.sdf.org servers. They quickly rushed to the servers to upgrade them, which fixed the issue. However threads is much much much larger than lemmy.world.
