Synchronizing owncloud's contacts and calendar with Android

Owncloud offers it's own calendar and it can also store contacts. These can be accessed via CalDAV and CardDAV internet standard. As of Android, there is no direct option to configure other DAV clients to be used, so there is need to use 3rd party application.

Sync script

The script in this post handles synchronization of files and folders. You can specify source and destination file. It's using timestamp of file and md5 sum to check if the file was modified.
I've created this script because I needed to sync several files/folders with owncloud folder.

My services

In this post, all services running on my Raspberry and some services on my laptop are shown.
This is just an overview for better imagination.

Setting up owncloud with nginx

Owncloud is the main service running on my raspberry. I'm using it for file uploading and sharing, contact and calendar synchronization with Android and to store bookmarks.
All this is running on nginx web server, which should be more lightweight than Apache, mariaDB and php-fpm.

My .vimrc file

For several years I have been using vim as my favorite console text editor. Vim is based on vi editor and stands for vi improved. To customize it, you can edit global configuration stored in /etc/vimrc (for Archlinux) or if you like to use your config file as user, create file .vimrc in your home directory.

Transmission daemon with proxy forward on nginx

On my Raspberry I use transmission daemon for downloading torrents. It provides web interface, where you can add new torrents to download.
In this article I'll describe hot to set up transmission daemon and use it with nginx.

Raspberry system information

Sometimes it is useful to see some basic information when logging onto your PI. In my case I wanted to see if some processes are running, so I created simple script, that writes those and few additional information.
