Seo Master present to you: Last week I hosted Chris Anderson for a Google tech talk on CouchDB as part of the Web E^xponents speaker series. Chris is an Apache CouchDB committer. He is co-author of the forthcoming O'Reilly book CouchDB: The Definitive Guide and a director of couch.io.

Making web applications work offline is a hot topic. Google Gears blazed the trail, and Web Storage is part of HTML5. CouchDB is a NoSQL alternative that makes it easy for web apps to run offline. This is important because even as bandwidth grows, latency is still an issue for a significant number of users, and outages or zero-bars can and do happen. CouchDB makes this a non-issue by running your application close to the user, on their device or in their browser. Chris calls this "ground computing" - a refreshing counterpoint to the oft-used "cloud computing" label. Hear more from Chris in his video and slides.

It was perfect timing for Doug Crockford, the legendary Ajax curmudgeon, to come to Google to discuss Gears and the mashup problem. The same week that he chatted about the issues that we face, we saw some innovation and fun mashups abound (for example, this Campaign Trails mashup created with the Google Mashup Editor).

Just a few days after we released the ability to do authenticated, cross domain mashups with Google Calendar the JupiterIT folk created Traffik, a mashup that combines your Google Calendar with a Google Map, allowing you to login to view private events and create news ones. It is great to see early experiments with the API such as the Digg Oracle's use of WorkerPool that we went into more detail on.

Vortex is another library that sits on top of Google Gears to add functionality through a nice layer of abstraction. The library will detect if you are online or offline, and have a system to handle one use case for sync issues. Brian Dunnington liked what he saw with the Dojo Offline Toolkit, and took a lot of the ideas from there, giving us a version that isn't coupled to a particular Ajax library. Libraries like this are exactly what we want to see. Gears is aiming to give the community rock solid, low level components, and we expect to see interesting abstractions on top. XMLHttpRequest is to Prototype/Dojo/GWT as Gears it to [insert your cool new offline framework here].

After the GWT 1.4 launch / coming out of beta was announced, Bob Vawter of the GWT team was able to let his hair down and he created a GWT application for the iPhone to see what the experience was like. His take-away was:

The Google Web Toolkit can be used to create applications that, in the same code base, work well on an iPhone and a traditional desktop browser.

You can read more about the development of the GWT Feed Reader.

In other GWT news we interviewed folks from Queplix, an open source CRM company, about their experience building their products which use a lot of GWT, various Google APIs, and even the Google Mini!

Sticking to JavaScript for just a touch more, the Google Maps API team have added a new Local Search Control which makes it simple to search the map that you are on. You can add this control to your Maps mashup with a line of JavaScript.

In other API news, Jeff Scudder announced a new release of the GData Python client library which gives you access to various new releases and a refactored codebase.

What else?

• T.V. Raman kindly stopped by for a podcast interview on accessibility which may have some data and thoughts that surprise you.
• The Joomla! team updated us on their Summer of Code experience
• And, for those of you who write test code, you may recognize the battle cry of: But it works on my machine!. John Thomas talks about the stability of your tests.

If you’re making a map of the world, you have to pay attention to the large fraction of the planet that’s beneath the water. That’s why Google Maps now includes underwater panoramic images from around the oceans. Naturally, there are a lot of wonderful sights to see, including a sea turtle with a school of fish and an ancient boulder coral. And just for fun, you can watch an underwater hangout from the Great Barrier Reef, without traveling to Australia or getting wet.



We don’t know if Google Maps has yet captured an image of a vampire squid (Vampyroteuthis infernalis). But researchers have found that this creature, whose name means "vampire squid from hell", has been more than a little overhyped. The vampire squid doesn’t hunt victims for blood. Instead, it eats random detritus floating around in the ocean. Still: great name!

Finally, the people who operate the International Space Station have a lot to do, such as making sure it doesn’t plow into any space junk. With that excellent goal in mind, NASA was considering moving the ISS this week to avoid an old satellite and a piece of rocket in its path. How do you move the ISS? By firing the engines of a docked cargo ship, of course!


Fridaygram posts are mostly for fun, not necessarily for developer stuff like our posts the rest of the week. This week Google turned 14 years old, and like lots of others its age, Google is already learning how to drive.
