Since the previous article Z story:using Django with GAE Python background captures the full text of multiple Web pages, the overall progress is as follows:
1. Added cron: Used to tell the program to wake a task every 30 minutes and run to the designated blogs to crawl the latest updates
2. Use Google's Datastore to store the contents of each crawler crawl. Only new content is stored.

Because GoogleAppEngine is walled, I cannot continue to improve my Movenproject, and I still have 20 + days to go back. I am afraid that I will forget the progress and details of the project, so I don't want to do anything cold, the general progress is as follows:

Our data storage automatically maintains indexes for you, so if you want to enable an instance in the data storage where we store the above structured entities, you can write a piece of code (using python ):
user_id_index = friendfeed.datastore.Index( table="index_user_id", properties=["user_id"], shard_on="user_id")datastore = friendfeed.datastore.DataStore( mysql_shards=["127

requests for "bare" domains, such as http://example.com/.App Engine does not support streaming media and long-term connections to your application's servers. Applications can use the channel service to push information to the browser in real time. In some cases XMPP using XMPP service is also a notification option (such as Google Talk). These mechanisms are better than polling techniques, and the client periodically asks for the latest changes to the application. polling is difficult to scale (

Some time ago, I downloaded the Windows 7 test version. There was no problem when installing vs2005. You can always encounter problems when installing ce6.0.

How to Create a grid with paginationIn this example, scripttagproxy is used because the sample code and the server code are not on the same server. In most cases, you can directly use httpproxy to obtain data on the same server.
The only difference between datastore and datastore is that you need to set the totalproerty attr
When the client stores data, we generally use cookies (non-sensitive data). However, as the client becomes increasingly rich, the amount of cookies that can be stored (up to 4 k per domain) is small.
LocalStorage is available in HTML5, but IE8-is discarded -. To ensure compatibility, we can find a storage method that I used a long time ago:
Add a special style url (# default # userData) to an element, and then you can use setAttribute and getAttribute to access data in the form of key-value pair
performance, in this case, you can use Proxy to act as the middleware and easily implement the log function:
