Step 1 - Make a Discord Webhook

Find the Discord channel in which you would like to send commits and other updates
In the settings for that channel, find the Webhooks option and create a new webhook. Note: Do NOT give this URL out to the public. Anyone or service can post messages to this channel, without even needing to be in the server. Keep it safe!

Step 2 - Set up the webhook on Github

Navigate to your repository on Github, and open the Settings

LLDB Debugging Cheat Sheet

Commands

LLDB Commands

LLDB comes with a great set of commands for powerful debugging.

help

Your starting point for anything. Type help to get a list of all commands, plus any user installed ones. Type 'help for more information on a command. Type help to get help for a specific option in a command too.

No problem,

run

git filter-branch --msg-filter "cat - && echo && echo 'Signed-off-by: Your Name <[email protected]>'" HEAD~2..HEAD

To sign-off the last two commits.

Then force to push them to the remote repo with the -f option:

Example: Moving up to a few commits to another branch

Branch A has commits (X,Y) that also need to be in Branch B. The cherry-pick operations should be done in the same chronological order that the commits appear in Branch A.

cherry-pick does support a range of commits, but if you have merge commits in that range, it gets really complicated

git checkout branch-B
git cherry-pick X
git cherry-pick Y

As configured in my dotfiles.

start new:

tmux

start new with session name:

	# Generate a new pgp key: (better to use gpg2 instead of gpg in all below commands)
	gpg --gen-key
	# maybe you need some random work in your OS to generate a key. so run this command: `find ./* /home/username -type d \| xargs grep some_random_string > /dev/null`

	# check current keys:
	gpg --list-secret-keys --keyid-format LONG

	# See your gpg public key:
	gpg --armor --export YOUR_KEY_ID
	# YOUR_KEY_ID is the hash in front of `sec` in previous command. (for example sec 4096R/234FAA343232333 => key id is: 234FAA343232333)
