## Unless you clear DerivedData folder, you can't mount ramdisk on it | |

# 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) |

It often be helpful to be able to debug memory usage in Swift on Linux, for example to debug memory leaks.
This is a quick overview of how to generate a report of memory usage for your Swift app. This guide will only show you how to generate the report, not how to analyze it, it might be written up in a blog post later.
First we need to install a tool called Valgrind, which is used to trace memory usage.
