This is a compiled list of falsehoods programmers tend to believe about working with time.
Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.
| # 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) |
