On an actual server, it is advisable to enable passwordless sudo for one user.
issue the command `visudo` and edit the sudoers file to contain the line:
``` default
cherry ALL=(ALL) NOPASSWD:ALL
```
That user can now sudo any root command, with no password login nor ssh in for root. And can also get into the root shell with `sudo su -l root`
On an actual server, you may want to totally disable passwords to
accounts that have sensitive information by corrupting the shadow file
```bash
usermod -L cherry
```
When an account is disabled in this manner, you cannot login at the
terminal, and may be unable to ssh in, but you can still get into it by `su -l cherry` from the root account. And if you have disabled the root account,
but have enabled passwordless sudo for one special user, you can still get
into the root account with `sudo -s` or `sudo su -l root` But if you disable
the root account in this manner without creating an account that can sudo
into root passwordless, you are hosed big time. So instead, once `ssh` is
working, give one user passwordless sudo, make sure you can ssh into that
account, and disable password and ssh access to the root account.
You can always undo the deliberate corruption by setting a new password,
providing you can somehow get into root.
```bash
passwd -D cherry

memory management design, though this misfeature seems common to
most operating systems.
When the OS detects the cpu idling while waiting for pages to be loaded
into memory, should disable one process so its pages do not get loaded for
a while, and derank all pages in memory that belong to that process, and
derank all pages that belong to processes waiting on that process. When the
cpu has idle time, and nothing to do for enabled processes, because
everything they need has been done, and is only awaiting for disabled
processes to get their pages loaded, then the OS can re-enable a disabled
process, whereupon its virtualed paged get loaded back into physical
memory, possibly resulting in some other process starting to thrash and
getting disabled. So instead paging out the least recently used page, pages out an entire process, and stalls it until the cpu is adequately responsive to the remaining processes, and has been adequately responsive for a little
while. This is inefficient, but it is a lot more efficient than a computer
thrashing on paging. If the computer is stalling waiting on page load, then
it is just running more processes than it can run, and the least recently used page algorithm is not going to accomplish anything useful. Some entire
processes just have to be paged out, and stay paged out, until the
remaining processes have completed and are idling. A thrashing computer
is not running anything at all. Better that is run some things, and from time
to time changes those things.
When the cpu has nothing to do because all the processes are waiting for pages to be loaded, something has to be done.

## Algorithm and data structure.
For this to work, the underlying structure needs to be something based on
the same principles as Git and git repositories, except that Git relies on
SSL and the Certificate Authority system to locate a repository, which
dangerous centralization would fail under the inevitable attack. It needs to
have instead for its repository name system a Kamelia distributed has
table within which local repositories find the network addresses of remote
repositories on the basis of the public key of a Zooko identity of a person
who pushed a tag or a branch to that repository, a branch being a thread,
and the branch head in this case being the most recent response to a thread
by a person you are following.
The Distributed hash table key will be:\
<<<<<<< Updated upstream
`human readable area of interest name/#public key of zooko name/
=======
`#public key of zooko name/
>>>>>>> Stashed changes
human readable branch name/#hash of data item`\
so that items that are likely to be looked up together will likely be near
each other on the same physical disk, and transmitted over the same
network connection. When someone approves of a text, then it goes into a
repository he controls or has write access to, and gets a corresponding key
in the distributed hash table.
<<<<<<< Updated upstream
=======
Which is not exactly a distributed hash table, for a hash table relies on the uniform distribution of hashes for its efficiency, and, because we want things likely to be looked up together at the same network address on the same physical machine, this is a very non uniform distribution. But it will still be efficient, because by the time you walk the network past the zooko
key, you will seldom have very far to walk. Walk the network to the end of
the zooko key, you are at a machine to which that identity has write
access, and thus, he has the authority and incentive to make things work.
Rather than being a distributed hash table, this is a distributed patricia tree.
But it will work if the person who controls a particular Zooko name
structures the data under his name in accordance with the characteristics of
the lookup process, and if he does not, other people will fail to find the material in his repositories, and that is his problem, which he can fix.
>>>>>>> Stashed changes
The messages of the people you are following are likely to be in a
relatively small number of repositories, even if the total number of
repositories out there is enormous and the number of hashes in each
repository is enormous, so this algorithm and data structure will scale, and
the responses to that thread that they have approved, by people you are not
following, will be commits in that repository, that, by pushing their latest
response to that thread to a public repository, they committed to that
repository.
Each repository contains all the material the poster has approved, resulting
in considerable duplication, but not enormous duplication.

-require only local lookup, which is faster and less costly than a distributed
-lookup. This is equivalent to a fully distributed hash table where the key is
-not hash of post, but global name of area of interest, zooko nickname,
-zooko public key followed by his human readable thread name (branch
-name or tag name in git terminology) followed by hash of post, so that
-items that are likely to be looked up together are likely to be located
-physically close together on the same disk and will be sent along the same
