Are there any objective differences between running NetworkManager and changing resolve.conf in the following manners? See method #1 and method #2 below. They appear to produce identical results in Ubuntu 18.04.



Method #1: resolv.conf



sudo rm -f /etc/resolv.conf

sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf

sudo gedit /etc/systemd/resolved.conf

# then added the google nameservers to my file, adding this line.

nameserver 8.8.8.8


Method 2: NetworkManager

    #1 changes the symlink for /etc/resolv.conf (to try and cure DNS resolution issues in 18.xx) and adds a nameserver (should use the DNS=) to systemd-resolve. #2 uses NetworkManager via a GUI to change the DNS servers. (Note: you really should settle down a bit and consolidate all of your various network questions, down to one question, accompanied by a little research first).

    Also, when starting graphic applications from the terminal command line, use sudo -H instead of just sudo, or you may create a login loop for your username.

List *all* the tuples!

Image
27 4 $begingroup$ Write a program, given an input n , will generate all possible n-tuples using natural numbers. n=1 (1),(2),(3),(4),(5),(6)... n=2 (1,1),(1,2),(2,1),(2,2),(1,3),(3,1),(2,3),(3,2),(3,3)... n=6 (1,1,1,1,1,1) (1,1,1,1,2,1) (1,1,1,2,1,1)... The output may be in any order that does not break any other rules. The program must be written to run forever and list all applicable tuples exactly once, in theory. In reality, your program will reach your integer type's limit and crash. This is acceptable as long the program would run infinitely long if only your integer type was unlimited. Each valid tuple must be listed within finite time, if only the program were allowed to run that long. The output may, at your option, include zeroes in addition to the natural numbers. You may choos...
