XCSoar VS BlueWallet

> Would you consider adding a kqueue implementation?

Can't do, I don't have Apple or BSD anywhere. But if code for it were submitted to me, I would gladly merge it (and try to keep the CI happy).

The MPD version of the event loop is portable and runs on macOS/BSD/Windows, but no kqueue, only poll() (and select() on Windows). This old-school API has its scalability problems, of course, but that matters not so much for MPD.

The event loop can already do Coroutines on all supported targets; here's another open source project where I use this library: https://github.com/XCSoar/XCSoar/tree/master/src/event/ - it's a flight computer (yes, for real airplanes) which also runs on Windows and macOS and iOS, and runs libcurl (and other stuff) as coroutine.

If you want to use my library and need help with integrating it or with adding kqueue support, get in touch with me.

In the unpowered flight world the most common foss navigation app is xcsoar: https://xcsoar.org/

It's probably because of some changes to the way application data in Android works now. There is an issue written up on the XCSoar GitHub here that describes the problem.

XCSoar 7.11: Tactical glide computer and maps

BlueWallet does not support Taproot, see https://github.com/BlueWallet/BlueWallet/issues/3880.

Thus you will import the seed into a better wallet like https://bluewallet.io that can sign the transaction

just use BlueWallet - https://bluewallet.io/ :-) I think it is easier than sparrow

https://bluewallet.io - excellent, easy to use wallet, Open Source and Non-Custodial

If $100 or more, there are some good suggestions like BlueWallet (https://bluewallet.io/).

Exactly this. Blockstream Jade hardware wallet used with Sparrow wallet on a laptop with linux, to make transactions. Then Bluewallet for a watch-only wallet on your phone device.

I also use my blockstream jade airgapped with sparrow wallet on a linux laptop which I have been extremely happy with. You can also use BlueWallet for phone.
