Use Tunlr on Boxee to watch Netflix outside of US (e.g. Germany, Switzerland)

The following how-to describes how you can watch Netflix on your boxee even if you are living outside of a country where Netflix is available. First of all you need a Netflix account. For USD 7.99 per month you can watch all their series and movies they have available. In my country VOD services cost that amount PER MOVIE!

Using munin to visualize your arduino sensor data

I was looking for the easiest way to visualize the sensor data my arduino in the basement is sending to the linux server. The server receives a data triple every few seconds which I write to a log file using cat: cat /dev/ttyUSB0 > /var/log/datalogger.log and the result looks like this: ... 0.10 58.60 23.00 0.25 58.60 23.00 0.22 58.60 23.00 0.21 58.60 23.00 ... .....

Exporting your App Engine Data with a Sitemap of Sitemaps

Currently there are about 200’000 archived items available in the Feederator database. In the hope to attract more traffic I wanted to make this data available to search engines. But how to make this data available to search engines without putting too much burden on my App Engine Quota. Certainly one big Sitemap wouldn’t work, because the call from a search engine would reach the 30 seconds limit of a Servlet call long before all .....

Feederator, Kindle and PDF

I’m using Feederator myself to send interesting posts to my Kindle to read it later. To do this you can simple drill into the detail view of a post. There you’ll find a social bookmarking widget, labled with “share”. In the popup select “more” and then search for instapaper. In order for this to work you need to setup an account at instapaper.com, but don’t worr.....

Speeding up data store queries with self-merge joins

For a while now Feederator allows some kind of full text queries. When items are read for the first time into the datastore an index will be created. This index is currently a break down of the single words in the title, but can be extended to the description and other attributes of an item. My first attempt of implementing the full text search on the AppEngine resulted in a very costly algorithm. The fulltext search index is stored as a.....
