I would like to hear some recommendations for running an app on a remote instance of Haiku. For instance, if I develop a Haiku app on a laptop from a coffee shop, how can I run the app on a different PC running Haiku in my basement at home?
You can use ssh, after configuring it and setting a password or public key.
If your app is graphical, you can use the remote app_server (we have an article about this on the website), or, if your local computer isn’t running Haiku, you will have to use a VNC server and viewer instead.
By the way, the latest VNCServer for Haiku is 1.27, available on Fat Elk’s repository. Useful if your other computer isn’t running Haiku.
