Porting legacy databases to Google App Engine : Thomas Brox Røst
Porting legacy databases to Google App Engine : Thomas Brox Røst: "This is a highly relevant problem if you are porting an existing Django application to the Google App Engine. Luckily, the App Engine SDK includes a bulk data uploader tool that does the job. Let’s work through an example where we use this tool to transfer data from an existing MySQL database onto a Django application running on Google App Engine."

Django snippets: "Partial Templates" - an alternative to "include"
Django snippets: "Partial Templates" - an alternative to "include": "This snippet adds simple partial support to your templates. You can pass data to the partial, and use it as you would in a regular template. It is different from Django's {% include %}, because it allows you to pass a custom variable (context), instead of reusing the same context for the included template. This decouples the templates from each other and allows for their greater reuse."

Channel API in AppScale - Raj's Blog (nlake44)
Channel API in AppScale - Raj's Blog (nlake44): "Google's newest API is the Channel API which allows for the pushing of messages to a client's javascript code. This blog entry explains AppScale's scalable implementation which is built using ejabberd and strophejs.
There are two sets of APIs for the developer. First is the python API which consists of create_channel(app_client_id) and send_message(app_client_id, message). The create channel API under the covers uses the xmpp service implementation of AppScale. We are able to leverage ejabberd to take care of the distribution and sending of messages for us. The trick here lies in that we must create temporary accounts with each new channel created. This requires garbage collection of channels which live on longer than a prescribe period of time. "

This creates a file blog-dump.bundle with the full history for master, including all parent commits. You now have a single file, which can effectively be mailed, downloaded via SCP or FTP, or simply moved to Dropbox (affiliate link) for safe keeping, or otherwise shared with others. Single files are easy to archive and backup."

The Anatomy of a Large-Scale Hypertextual Web Search Engine - Stanford InfoLab Publication Server
The Anatomy of a Large-Scale Hypertextual Web Search Engine - Stanford InfoLab Publication Server: "In this paper, we present Google, a prototype of a large-scale search engine which makes heavy use of the structure present in hypertext. Google is designed to crawl and index the Web efficiently and produce much more satisfying search results than existing systems. The prototype with a full text and hyperlink database of at least 24 million pages is available at http://google.stanford.edu/."
