Google Developer Courses on YouTube

Wow, it's been nearly 4 months since we started the Google Developers channel on YouTube! We wanted a place to post talks, announcements, interviews, and anything else that might interest outside developers (and other fans). Now, we're building out more tutorial / lecture content -- something that hobbyists and seasoned programmers can watch to get their feet wet with our products.

We know that one of your New Year's resolutions must be to learn a new API, so check out our first videos on Gadgets and Google Data:

Three videos about Getting Started with Gadgets by "the Dans" (Daniel Lee and Daniel Holevoet):

Google Gadgets going cross-platform

By Mike Pinkerton, Software Engineer

For about two years now, people have been writing gadgets for Google Desktop on
Windows and for iGoogle on the web. Today, with the announcement of Google
Gadgets for Mac OS X, Google Desktop users on the Mac can now run the same
Windows and web-based gadgets in Apple's Dashboard with zero (or very few)
changes. Check it out for yourself.

Google Gadgets for the Mac uses WebKit's JavaScript engine inside Dashboard, so
the majority of gadgets just work if they're written properly. The rest can be
fixed by following a few guidelines:

• Use JavaScript, not JScript
• WebKit is case-sensitive, JScript is not, which can lead to problems if you assume can you do things like interchange SetTimeOut() and setTimeout().
• Avoid JScript-only features like collections and ActiveX.
• Avoid IE-specific DOM extensions, just as if you were writing a multi-browser web application.
• Avoid Windows-specific APIs
• You shouldn't assume ActiveX or certain DLLs are available. Neither WebKit nor Mac OS X supports ActiveX, so these gadgets must be rewritten.
• Avoid Windows-only APIs such as Google Talk. These APIs are not (yet) available on Mac OS X.
• Understand how Dashboard is different
• The Dashboard environment is very different from a web page or the Desktop sidebar on Windows in that it comes and goes as the user activates it. Don't rely on your gadget always being visible. Your gadget won't run or update when Dashboard isn't in the foreground.
• Don't rely on access to the file system. The security model for Dashboard doesn't allow arbitrary file access to the hard disk, although your gadget does have access to files in its own archive. Things like file pickers won't work. Note that while restricted file system access is a departure from how gadgets work on Windows, it's consistent with Dashboard's security model and the behavior of other widgets developed for Mac OS X.

For more details, see Writing a Cross-Platform Gadget, part of the Desktop Gadget API documentation.

If you're interested in developing your own gadget, visit the Gadgets API homepage. If you're already a gadget developer, download the beta today to test your gadget and ensure that it works correctly.

Introducing Calendar Gadgets

By Michael Bolin, Google Calendar Team

You've seen them on iGoogle, in IBM WebSphere Portal, and now you can find them in your favorite online calendar -- that's right, now we're supporting Gadgets in Google Calendar! If you're a Scorpio like me, you can add this gadget that lets you check your horoscope from your calendar (don't worry, all the signs of the zodiac are supported). And if astrology isn't your thing, how about games? This Sudoku gadget was created by Alex Komoroske, one of our interns on the Docs & Spreadsheets team. If you add the gadget, you'll see that the daily puzzles get harder throughout the week.

Finally, if you like to keep up on celebrity birthdays, the birthday reminder will show you who you are idolizing that day:



But you don't have to be a Googler to create a Calendar Gadget -- we have put together new documentation to help you get your favorite Gadgets into Calendar. If you are itching to write some code, then you can use GData or ICAL to add some fancy Calendar Gadget events to your calendar. But if you're out of Red Bull and don't have the time for a late-night hacking session, then you may want to try our new "of-the-day" Calendar Gadget wizard, which makes it easy to take an existing Google Gadget and have it show up once a day, every day, just like the Horoscope and Sudoku Gadgets do.

Let us know how your experiences with Calendar Gadgets are going in the Google Calendar GData API developer forum.

News

The following are links that we mentioned in the podcast:

AppleScripting Google Desktop means that you can tell the Google Desktop application to do things for you via script. Boss around the system from your own applications and scripts.

The new Google Earth Outreach program has some tutorials such as showing you how to create KML from a spreadsheet.

The Google Mashup Gallery is a mashup itself, that allows you to add your mashup to the mix. Now, everyone will be able to find your Britney vs. Christina mashup!

Geotagged Picasa JSON/KML Output + Driving Directions = Instant Scenic Tours: If you were following the Google blogs yesterday, you would have heard that Picasa now gives you a sleek drag+drop interface for geotagging your photos, and that the Picasa Google data API now outputs the geotagged data using GeoRSS & GML elements. And if you were excited by all that news and immediately visited Picasa to try out the new feature, you might have noticed the big blue KML icon next to a "View in Google Earth" hyperlink. So Picasa now gives developers geotagged photo data both in KML output and the standard Google data API output formats, and that means we map developers have a lot of ways to start playing around with Picasa photos.

New drag-to-route driving directions in google maps - once you have a route, drag the blue line around to have it automatically re-route using your desired roads or intermediate destinations.

Convert Google Gadgets to Other Widget Platforms

Post by Dann Lee, Associate Support Engineer

The Google Gadgets directory contains thousands of gadgets you can use on various google.com sites. In October 2006, we released Google Gadgets For Your Page, allowing you to embed your favorite gadgets in your blogs, websites, and other webpages. Now you can take Google Gadgets and convert them to run in your Windows Vista Sidebar or Mac OS X Dashboard. With the use of third-party utility applications, this is trivial to do.

Mesa Dynamics offers a free widget converter application called Amnesty Generator which converts Google Gadgets to Mac OS X Dashboard Widgets. On February 2nd, they announced a public beta release that's capable of converting Google Gadgets to Windows Vista Sidebar Gadgets as well. This increases distribution of Google Gadgets further and gives gadget authors access to an even wider audience. In addition to Amnesty Generator, Widgetops Universal Google Gadget Widget is a Mac OS X Dashboard Widget that converts Google Gadgets to run on the dashboard.

Viewing Google Gadgets on different sites or platforms does not require any changes. The answer to the question "Why should I write a Google Gadget?" is hopefully becoming more and more clear as rendering platforms become increasingly available, which now includes:

• Google Personalized Homepage
• Google Gadgets For Your Webpage (anywhere on the web)
• Google Page Creator
• Google Desktop
• Windows Vista Sidebar (converter)
• Mac OS X Dashboard (converter, dashboard widget converter)
