Code Review: Start your App Engine and run the cloud offline with your docs

The big buzz continues to revolve around our Google App Engine launch. We are seeing a host of applications being developed, and were even pleasantly surprised to see people port the APIs allowing you to run App Engine code elsewhere, such as

One interesting feature to the App Engine which you may not have noticed, is the integration with Google Apps. Not only can you tie an application to your domain (allowing you to have instead of but you can restrict access to the given application to only members of your domain. If I ran a company on Google Apps, this would be a nice addition. I could see the small business apps that I need running there.

Jeff Scudder then released a new version of the Google data Python client library which has support for Google App Engine and the Contacts API. If you want to use this in your Google App Engine application you simply need to set gdata.service.http_request_handler = gdata.urlfetch to make sure your requests have a path out!

Google Docs offline, and Gears

I was on the road, speaking about Gears and the Open Web in Europe last week, and it was perfect timing to be mixing with the community as Google App Engine came out and I could talk to that too. We also had a few things to talk about with Gears.

We have been getting lots of questions surrounding our stance with the various standards out there, so Aaron Boodman put down our thoughts on the matter in a piece called Gears and Standards. It talks about how we are working with HTML5, and the direction that you will see Gears going. I think it is incredibly exciting to see people realise how Gears is a lot more than "offline", and is actually an open source way to teach browsers new tricks.

Brad Neuberg talked about just that as well as new features in Gears, and tools to help you get your work done, such as PubTools. He also discussed our first Google Gears for Mobile application, done by the Picasa Team. Now the blokes in London can show off pictures of their kids as they slow poke through the city down in the tube.

The biggest news of all though was the launch of Google Docs offline. If you have ever been in the situation where the internet goes flaky right when you just need that bit of info in document, no more. Now you have the option to save docs locally on your computer, so you can access them no matter where you are.

If you would like a refresher course on how to get started with Gears check out Ben Lisbakken's new screencast.

Fun with Maps

The Geo side of the house continued to output great content, including a series of Geo Developer content:

They were also happy to announce that KML is now a standard, and owned by the Open Geospatial Consortium. We have seen a lot of other sites consume and produce KML, so this is a great step.

Finally, a great new feature was added to Google Maps. You can now check out traffic patterns in the future. If you have a commute the following morning, you can check out an estimate of how stuck you will be based on past experience. Obviously, it can't determine if there will be any crashes or anything like that :)

And there's more...

To finish up, a few other interesting items of the week:

I hope you had a great week. Remember that our big developer event Google I/O is now just a few weeks away! We have a few posts from presenters who will be at the event to give you a little look at the content, but the best part will be having the community together to talk in the open.
