MOTA (Many of the Above) is Honest voting - you dont have to fear about vote wasting

This is very easy to describe to voters: vote for everyone you approve of.
MOTA does one thing very well - it removes any reason to vote against your favorite candidate.

Intuitive Explanation

In any voting system, if there's only ONE candidate - not voting and voting for the candidate are the same.
For TWO candidates - it is better to pick the one you like more.

• if CBV terminates, then so does CBN - since CBN will evaluate less than or equal parameters than CBV
• CBV avoids repeated recomputation of values
• force scala to do CBN, by defining def fun(x:Int, y:=>Int)
• disjunction and conjunction (&& and ||) are short-circuit operators - the right side will only be evaluated in certain cases.
• in certain cases like

  if(r==0)
    return 1

  there is an error Scala: type mismatch; found : Unit required: Boolean
  • this happens because you have to have an else clause, otherwise the type checker doesn't know what the return type is when it's not the case
• return fn(a-1) is tail recursive but return n * fn(a-1) is not

1. If ur upgrading from an older fedora,
  1.1 `sudo dnf remove docker-*`
  1.2 `sudo dnf config-manager --disable docker-*`
  1.2 please ensure `/etc/default/grub` doesnt contain `systemd.unified_cgroup_hierarchy=0`. If it does contain, then remove it and run `sudo grub2-mkconfig -o /boot/grub2/grub.cfg`
2. reboot
3. set firewall correctly using `sudo firewall-cmd --zone=docker --change-interface=docker0`
4. in `/etc/sysconfig/docker` please ensure `--live-restore` is removed
5. reboot
6. docker should work
