Using multiple github accounts with ssh keys

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

  1. Generate ssh key pairs for accounts and add them to GitHub accounts.

Python implementation to send a fake SSDP discovery message to Bambu Studio or Orca Slicer
# Derived from this: https://github.com/gashton/bambustudio_tools/blob/master/bambudiscovery.sh
# Python implementation without need for linux
# Send the IP address of your BambuLab printer to port 2021/udp, which BambuStudio is listens on.
# Ensure your PC has firewall pot 2021/udp open. This is required as the proper response would usually go to the ephemeral source port that the M-SEARCH ssdp:discover message.
# But we are are blindly sending a response directly to the BambuStudio listening service port (2021/udp).
# Temporary solution to BambuStudio not allowing you to manually specify the Printer IP.
# Usage:

The issue:

..mobile browsers will wait approximately 300ms from the time that you tap the button to fire the click event. The reason for this is that the browser is waiting to see if you are actually performing a double tap.

(from a new defunct https://developers.google.com/mobile/articles/fast_buttons article)

touch-action CSS property can be used to disable this behaviour.

touch-action: manipulation The user agent may consider touches that begin on the element only for the purposes of scrolling and continuous zooming. Any additional behaviors supported by auto are out of scope for this specification.
