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?

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

If anyone is interested in setting up their system to automatically (or manually) sign their git commits with their GPG key, here are the steps:

Generate and add your key to GitHub
$ git config --global commit.gpgsign true ([OPTIONAL] every commit will now be signed)
$ git config --global user.signingkey ABCDEF01 (where ABCDEF01 is the fingerprint of the key to use)
$ git config --global alias.logs "log --show-signature" (now available as $ git logs)
$ git config --global alias.cis "commit -S" (optional if global signing is false)
$ echo "Some content" >> example.txt
$ git add example.txt
$ git cis -m "This commit is signed by a GPG key." (regular commit will work if global signing is enabled)

Linux command to hibernate and then reboot into a different OS

In this document I describe my setup about how to add a menu shortcut that will hibernate and reboot the system into a different OS (in my case, Windows), and then restore linux on the next reboot.

For this, I'll be using Arch Linux with systemd-boot as my boot manager, but in practice any bootloader that handles the LoaderEntryOneShot (a.k.a. BootNext) efivar should work.

NOTE It is advisable to not do this with window's fast boot feature active, since alternating the hibernation of two systems can cause shared partitions to get corrupted. However, if additional steps are taken in order to ensure the shared partition are unmounted before reboot, or no partitions are shared between the two OSs, this can be made to work with fastboot enabled which should give quite a boost in Windows' startup time.

Set the LoaderEntryOneShot/BootNext EFI variable
