Renaming software projects
--------------------------

I renamed "django-north" to "North" on PyPI.

Here is how I did it:

- Run `pip uninstall django-north`

- In setup.py, change `name` from "django-north" to "North"

- Run `python setup.py register`. This is the final confirmation 
  that nobody else had registered this name before.

- Run `pip install -e t:\hgwork\north`

So the Python package name and my internal name are "north", 
on PyPI it is now "North".
And on Google it continues to be "django-north" because I don't believe 
it is possible to rename a project there as easily.

I then also renamed "django-site" to "DjangoSite" on PyPI.
Which I then regretted and undid.
So for `django-site` the Python package name is "djangosite",
my internal name is just "site", and the official names on PyPI 
and Google are "django-site".

I should probably also rename "lino" to "Lino".
But "lino-welfare" should remain lowercased.

Uh! The rules of naming software projects would 
deserve a whole book to be written by a linguist...


setup.py register says TypeError: 'NoneType' object has no attribute '__getitem__'
----------------------------------------------------------------------------------

In a first attempt of `python setup.py register` I had the 
following error message::

  running check
  Traceback (most recent call last):
    File "setup.py", line 4, in <module>
      setup(**SETUP_INFO)
    ...
    File "c:\Python27\lib\site-packages\docutils\nodes.py", line 1021, in set_id
      for id in node['ids']:
  TypeError: 'NoneType' object has no attribute '__getitem__'


This was because I used the text role "xfile" 
(unknown for PyPI which uses only docutils and not Sphinx) 
in my :xfile:`README.txt` file::

  Basic usage in your :xfile:`settings.py` file is...
  

Tutorial: Multilingual database content using North
---------------------------------------------------

I wrote a new tutorial about *multi-lingual database content*.
`north:mldbc_tutorial`.
Also updated documentation about `north:mldbc`

Started to used InterSphinx references.

`Multilingual database content using North
<http://north.lino-framework.org/tutorials/babel.html>`_.
This is a tested document and a first useful application 
of what I've been doing last week.

Also note the new method 
:meth:`djangosite.Site.call_command`...
that would deserv e another new chapter in djangosite.

Lino is currently growing more quickly than I can write...


rsync without password
----------------------

Until now I wasn't too much disturbed by the fact that rsync asks me 
for a password each time I publish the html generated by Sphinx 
to LF. Yes annoying, but rsync was still much quicker and 
easier to use than any other method I've tried.

But that's because I had never managed 4 software projects in 
parallel before. Now it was time to solve this old issue.

I had already used 
`ssh-keygen <http://linux.die.net/man/1/ssh-keygen>`_
before, so I had my key pair.
The problem was that I had generated it with a passphrase.

But in ssh-keygen_ I read how easy it is to remove the passphrase:

  $ ssh-keygen -p
  Enter file in which the key is (/home/luc/.ssh/id_rsa):
  Enter old passphrase:
  Key has comment '/home/luc/.ssh/id_rsa'
  Enter new passphrase (empty for no passphrase):
  Enter same passphrase again:
  Your identification has been saved with the new passphrase.


Another thing:
On the remote machine (where I have root access), 
in :file:`/etc/ssh/sshd_config` I had to 
find the `AuthorizedKeysFile` parameter and uncomment it::

  RSAAuthentication yes
  PubkeyAuthentication yes
  AuthorizedKeysFile      %h/.ssh/authorized_keys

Then again on the remote machine I 

.. code-block:: bash

  $ nano ~/.ssh/authorized_keys
  $ chmod og-r .ssh/authorized_keys
  $ chmod og-rwx -R .ssh
