Get ASHandle of a domain

I wanted to get all IPs that belong to facebook.com.

The command I found is the following

whois -h whois.radb.net -- '-i origin AS32934'

whois -h whois.radb.net -- '-i origin AS32934' | grep ^route

normoes

Python and privy

python -c "import privy; hidden=privy.hide(secret=b'test', password='passwd', security=2); print(hidden); plain=privy.peek(hidden=hidden, password='passwd'); print(plain.decode())"

Output:

To calculate the correct value for shared_buffers in a AWS RDS PostgreSQl database:

(2*1024*1024*12.5/100)/8)
# = 32768

This is more or less a sequence of manual steps, because I don't want to remove volumes I might still need, especially if no containers are using those volumes at the moment.

This is also why I, sometimes, prefer the following over: docker volume prune.

In situations where I have literally thousands of docker volumes, basically after a long time of not removing any docker volumes, the following comes in handy.

At first I get the 200 (just some number) biggest docker volumes (as root). I exclude containers, that contain postgres or redis in their names, essentially allowing the removal of all other volatile containers, named and unnamed.
