nautilus-gps-link.sh will show the GPS position of the selected image in Google Maps.
If multiple images are selected, the first 10 GPS positions will be displayed in a static Google Map (did not find out how to display multiple markers in a dynamic map)
Zenity is used for displaying a progress bar, so please make sure to have zenity installed as well.

nautilus-gps-place.sh will show the nearest place to the GPS positions of the selected image in a dialog using zenity.
#!/bin/bash
gpsPlaceName.sh -v "$@" | tee /tmp/gpsPlaOutxxx.txt | zenity --progress --pulsate --auto-close ; zenity --text-info --filename=/tmp/gpsPlaOutxxx.txt --width 800 --height 800 ; rm /tmp/gpsPlaOutxxx.txt

Example Dialog:

To integrate this into Nautilus you should install nautilus-actions, then run nautilus-action-config-tool to add new entries:

But if you just want to show the GPS postition of a single image quickly, digikam is to heavyweight.
Many small tools can show the exif metadata of a picture, but the plain GPS coordinates are not very helpful to find out where a picture has been taken.

For this reason I have created a set of small scripts which do the following
1) Extract the GPS coordinates and get the name of the nearest place/city/village (thanks to geonames.org)
2) Open the GPS coordinates in Google Maps
3) Show the GPS coordinates of up to 10 pictures in a Google static map

The main script (gpsPlacenames.sh) provides the core functions and can be used on the shell.
The two helper scripts (nautilus-gps-link.sh, nautilus-gps-place.sh) are used for integrating it into nautilus and providing X window dialogs using zentity.

Now, you can easily get the GPS place names for all you images on the command line and use the printed links to jump directly to the GPS coordinates in google maps .
Cool huuh ?

The migration was very error prone, because Wordpress adds a “br” after each line. Also Strato does not
allow to use a custom theme and the build-in theme has only a width of 800px.

So, the most blog entries are readable but not very nice. The Nanoblogger page was ways nicer.
Here a short summary:
Strato Weblog Basic (WordPress) Advantages / Disadvantages
++allows users to comment a blog entry
+easy management via web sites
+easy upload of files
–The default theme is limited to 800px width
–Strato doesn’t allow a custom theme
-The management via web sites is slow

It required the following jars which you can find here: http://jakarta.apache.org/commons/
-commons-logging
-commons-httpclient
-commons-codecs

Example command to view live video on linux:

java -cp
commons-httpclient-3.0.1.jar:commons-logging.jar:commons-codec-1.3.jar:MDGrab.jar
de.dietzm.webcam.MDGrab 192.168.0.55 - admin adminpw | mplayer - -demuxer mpeg4es -msglevel all=1

A detailed description will follow.

Try it out ! If your Webcam doesn’t start anymore, you can reset it to the factory defaults.
With some effort it should also be possible to install a telnet or ssh binary to get remote access
Please keep me informed If you managed to get remote access.

Here is the process list of my webcam:

To start the video grabber command line tool, enter the following command:
java -jar MDGrab.jar [webcam IP-Address] [output filename]

It has multiple TCP Ports open:

Port 80 = Web Interface. All commands to control the webcam (pan&tilt…) are http requests.It also handles the authentication
Port 5000 = Stream initialization.
Port 5001 = Streaming Port, sends the video packets
Port 500 = documented as ipview port. But ipview pro does not connect to this port !
dynamic Port = UPnp Mediaserver port

The following sequence is used to start the video streaming:
1) connect to port 80 and authenticate (http authentication)
2) connect to port 5000, send a init sequence and disconnect
3) connect to port 5001, send a start sequence and receive the video stream (with a cellvision header in each packet)
