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.....

Plenty of new tricks for Feederator

This weekend Feederator learned a lot of new tricks. In my opinion the coolest new thing is that Feederator adds a lot of additional data to each post. You get a website preview in the list with the feed items. In case of movie feeds this might even be a cover picture. You only get to see this if you are in “expanded” view mode. If the pictures annoy you – just sw.....

Capture web page screenshots headless

For a while now I have been using the Amazon cloud to render web page previews for posts in Feederator. This solution is running in Amazons new free “beginner” quota. For a low load this works quite well, but it never worked to create a thumbnail for all incoming items. I guess it wasn’t working reliably because for every call a virtual framebuffer has to be started, then firefox, then the screenshot and so on… From tim.....

How to delete index on App Engine for Java

At the time of this writing there is no function to delete (unused) your datastore indexes directly with the Java tool set. But there is a way around: the python SDK has a function called vacuum_indexes. This is how your can do it, step by step:Install the Google App Engine for Python SDK and follow the steps described for your operating system here: http://code.goo.....

New Features: Searching the archive

I’m trying to improve Feederator.org. Sometimes changes are rather invisible to the end user. Sometimes new features extend the use of feederator rather dramatically. I enabled such a feature today: searching the archives with full text key words. To keep your inbox clean Feederator moves items older than 3 days to the archive. Once they are in the archive you can search for them. Make sure that your most significant word comes first, otherwise it might be omitted. The search is n.....

Combine Feederator and Sabnzbd+ to a One-Click-Download tool

Sabnzbd+ is a great tool if you are riding the usenet wave. Feederator on the other hand is a great tool to manage and moderate (RSS) feeds. This post will show you how to use the two tools to have a one click (movie/series/ebook) download tool. First of all you need a usenet account. I’m using supernews (http://www.supernews.com/) which will cost you between $10-$12 per month. Use Google search to find special offers for $9.99. Then downlo.....

New Feature: Copy items to another feed

Since feederator is only a free time project, it takes time to implement all the features that I want feederator to have. I’m stealing here a bit of time, there using a gap between coming home from work and dinner. The guys over at lifehacker recently wrote a nice article about this productivity technique and it works just like that for me. But now, let’s get to the poin.....

New Layout

More and more, the current layout seemed not to be as convenient as we first thought. The layout looked like it was designed with a mobile device in mind, than running nicely on a desktop. But since it is our long term plan to bring Feederator also to mobile devices, that experience wasn’t in vain and we keep the layout at hand for that time. But now, let’s talk about the new layout: it is inspired by the GMail layout: on the left you have your folders, in our case the feed.....
