Odroid-U3 XuBuntu – no image wrong HDMI-Setting. Reset HDMI-settings

If you don’t get an image via HDMI on your TFT/TV, sometimes it’s because of a wrong setting… and if you can’t connect to your Odroid with SSH (to run odroid-config), you have got a problem :-( but just a small one.

Put the SD in a Card-Reader and connect it to a Linux-PC.

The first partition, a fat partition will have a file named boot-auto.scr copy it to boot.scr (replace the old boot.scr there)

odroid_bootscr

Now your little gadget should boot with an image on your screen :-)

Use BaseMap-Austria (basemap.at) with QGIS 2.x and ArcGIS 10.2.x

The Austrian  govermental geodata-departments offer a free Basemap for Austria – Basemap.at (http://basemap.at/) – similar to GoogleMaps or OSM, based on official governmental data.

You can access this map via QGIS too – add a WMS/WMTS-Layer and use the following URL

http://www.basemap.at/wmts/1.0.0/WMTSCapabilities.xml

basemapATQGIS

… for the best rendering-quality (no distortions) choose Google’s Pseudo Mercator as Project(Display)-CRS: EPSG 3857 (in QGIS 2.x: Settings – Project properties)

QGIS 2.0.1 on Fedora 20: Problems with “Raster-Menu”

After having QGIS 2.x successfully installed on Fedora 20 (yum install qgis) only the QGIS itself seems to be installed. You may get errors when trying to fetch new Plug-ins (Python!) or you have an nearly empty Raster-menu (without the GDAL-Tools).

In these cases install the following packages with YUM:

  • qgis-python
  • gtatool-gdal
  • gdal

Screenshot-example (error): Missing GDAL-Lib – although the menu-items are in place:

After installation of the above mentioned packages everything works fine 🙂 – e.g. hillshade and contour-lines

Amazon Kindle & Linux… and how to remove DRM

Kindle and Linux

There are useful tools around to handle your Amazon Kindle:

  • calibre – a nice piece of software to manage your books (library) on your kindle. This tool also converts and sends books to your device. The all in one solution. It is extremely expendable with Plug-Ins (also for removing DRM)
  • ebook-convert and other commandline-tools (gets installed with calibre)
    example: ebook-convert filename.cbz filename.epub

Removing DRM with Python tool

  1.  What you need: Python on your system – just try “python” in CLI. If Python is missing in your distro install it – e.g. in Ubuntu by “sudo apt-get install python”
  2. The MobiDeDRM Scripts – http://nyquil.org/uploads/MobiDeDRM.zip
  3. If you buy a book from Amazon you normally get a “Book.azw”-File…
  4. … the next steps:
  • python kindlepid.py XXXXXXXXXXX” where XXXXXXXXXXXX is your 16-character Serial (get your serial from your Kindle Systeminformation – Settings/Device information). The Terminal window will return something like Mobipocked PID for Kindle serial# XXXXXXXXXXXXXXXX is Z1QFCDQ*74. That “Z1QFCDQ*74” string is what you need.

  • Now all you have to do to remove the DRM from the .AZW file is:
    python mobidedrm.py Book-Title.azw Book-Title.mobi YourMobiPocketKEY
    In a minute or so you should have a DRM-free MobiPocket book you can later convert in any other format you like. If that doesn’t work, try
    python mobidedrm2.py Book-Title.azw Book-Title.mobi YourMobiPocketKEY
