-====== Nokia N9 For Linux Users ======
-Since about 20% of our lab are N9 users, it seems worth maintaining a page for sharing tips and tricks.
-===== Synchronizing Contacts and Calendars =====
-If you do not want to entrust your data to //The Cloud//, you can sync the N9 directly to the desktop.  Here is the most functional way I found:
-  * On the N9, install [[http://people.debian.org/~ovek/harmattan/|syncevolution_*_armel.deb]].
-  * On the host PC, run ''syncevo-http-server -q %%http://localhost:9000/syncevolution%%''.
-This allows [[http://syncevolution.org/wiki/synchronizing-evolution-http-howto|synchronization]] of the contacts and of multiple calendars.((Contacts sync appears to require a login shell on the N9. Thus, my sync script fires it up with
-  ssh user@192.168.2.15 "sh -l -c 'syncevolution -q client-for-laptop addressbook'"
-))
-Todos and notes cannot currently be sync'ed in this way, but this may [[http://lists.syncevolution.org/pipermail/syncevolution/2012-January/003289.html|follow]] at some point.
-There does not currently seem to be a straightforward way for SyncEvolution to sync over [[http://lists.syncevolution.org/pipermail/syncevolution/2012-January/003291.html|Bluetooth/OBEX]]. One can use the N9 built-in SyncML client to sync with a desktop Evolution server over Bluetooth, but this solutions apparently has its [[http://lists.syncevolution.org/pipermail/syncevolution/2012-January/003279.html|weaknesses]].
-I do not miss Bluetooth sync much, as I need to keep the USB cable around for recharging anyway.
-===== Synchronizing Notes =====
-Notes can be sync'ed both ways as follows:
-  * On both the N9 and on the host system, install ''git''. On the N9, create a bare git repository.((The need for ''git'' on the N9 can be avoided entirely by ''sshfs''-mounting the N9 and doing all of the following on the host system.))
-  * Place all your notes in flat files, one file per note.
-  * On the N9, place a couple of scripts that ''git push''((
-  PATH=$PATH:/usr/libexec/git-core
-  cd $1
-  git status | grep 'nothing to commit (working directory clean)'
-  if [ $? != 0 ] ; then
-    git add -A
-    git commit -m "sync commit"
-    git push
-  fi
-)) and ''git pull''((
-  PATH=$PATH:/usr/libexec/git-core
-  cd $1
-  git pull
-)) your Notes directory.
-  * A full sync is then done by something like the following sequence:
-    - ''push'' on the N9
-    - ''pull'' on the host
-    - ''push'' on the host
-    - ''pull'' on the N9
-Voilà. Much better than conventional solutions, since notes are sync'able even if they are simultaneously edited on both sides. And you get to keep your entire history.
-The drawback is lack of integration with the N9. Editing notes can be tedious. You can alleviate this a bit by [[http://harmattan-dev.nokia.com/docs/platform-api-reference/xml/daily-docs/libcontentaction/index.html#xdgmimehandling|configuring]] the N9 to open text files inside ''nano'' instead of the document viewer.
-**Warning:** I have not yet tried what happens in case of a merge conflict. In any case, they will require manual fixing.
-===== Synchronizing Sensitive Data =====
-Many people carry sensitive data around with them, such as passwords.  There are various //keyring//, //wallet// etc. programs out there to maintain these in an encrypted fashion, but I did not find a good solution for the N9, at least none that allowed any straightforward way of sync'ing such data with the desktop. But here is a simple solution that covers most use cases:
-  * On both the N9 and on the host system, install ''gpg''.
-  * Keep all your encrypted data in a subtree of the file system, one record per (encrypted) file.
-  * Sync this directory subtree from the desktop to the N9 using ''rsync''.
-  * [[http://harmattan-dev.nokia.com/docs/platform-api-reference/xml/daily-docs/libcontentaction/index.html#xdgmimehandling|Configure]] the N9 to associate with ''.gpg'' files the action of decrypting to ''stdout'' inside the Meego Terminal.((Here is my ''/usr/share/applications/decrypt.desktop'' on the N9:
-  [Desktop Entry]
-  Name=Decrypt
-  Comment=Display GPG-encrypted text/plain files
-  Exec=/usr/bin/meego-terminal -e sh -c "/usr/bin/gpg --decrypt %U ; read"
-  Type=Application
-  MimeType=application/pgp-encrypted;
-))
-Voilà.  Much better than any keyring/wallet program, at least for Emacs users. To consult a password on the N9, simply open the file in a [[http://store.ovi.com/content/204982|file manager]], and it will pop up the terminal, ask for your passphrase, and dump the record to the screen.
-The drawback is that encrypted files can only be edited on one of the two machines, not on both.
-===== Offline Reading =====
-I have a little script that pulls a URL with prerequisites using ''wget'', cleans the pulled HTML files with ''tidy'', and strips out all ''<script>''s with a tiny XSLT transformation (I do not know of a way to turn off Javascript with the stock Web browser). The whole batch is then moved to the N9 by my sync script, and I always have a bunch of offline reading material with me.
