Seo Master present to you:

Today we announced a fun 20% robotics project that resulted in three ways you can play with your iRobot Create®, LEGO® MINDSTORMS®, or VEX Pro® through the cloud. We did this by enhancing App Inventor for Android, contributing to the open source Cellbots Java app, and beefing up the Cellbots Python libraries. Together these apps provide new connectivity between robots, Android, the cloud, and your browser.

You can start empowering your Android phone with robot mobility by picking the solution below that matches your skill level and programming style:

• App Inventor for Android
  This is an entirely cloud based programming environment where you drag and drop elements into a project right within your browser. The latest features for robots include a low level Bluetooth client for connecting with many serial-enabled robots, and tight integration with LEGO MINDSTORMS. There are seven LEGO components in all, with NxtDrive and NxtDirectCommands used for driving and basic control while NxtColorSensor, NxtLightSensor, NxtSoundSensor, NxtTouchSensor, and NxtUltrasonicSensor are used for sensors.
  
  Also be sure to try out the social components to connect with Twitter, and TinyWebDB for hooking up to AppEngine. All of these can be used together to make your phone a powerful robot brain.
  
  
  
• Cellbots for Android
  
  We wanted to offer a flexible application that could drive multiple platforms and support different control modes. To do this we created the Cellbots Java application which currently supports four robot platforms and allows additional robot types and UI control schemes to be added using the standard Android SDK. It is entirely open source and available for free in the Android Market so you can try it out right away.
  
  With it you can use the phone as a remote control with D-Pad, joystick, accelerometer, or voice control inputs. Then try mounting your phone to the robot in brain mode where you can stream video back to a web browser and make the robot speak using Android’s native text-to-speech. For those of you with two Android phones, we support remote-to-brain mode where you can ask the robot for its compass heading or change the persona on screen.
  
  
   
  
  
• Cellbots Python library
  
  The 20% team got together to create a more modularized version of the popular Cellbots project, which is all open source code. The goal for the Python library is to allow developers an easy way to demonstrate the features on Android phones suitable for robots. There are commands to make it speak, listen, record audio, take pictures, get a geolocation, and of course provide the I/O to the bot.
  
  The Python code is the most flexible in terms of connectivity with support for Google Talk chat over XMPP, HTTP through a relay or direct connection, telnet, and voice input. To use it you just need to install the Scripting Layer 4 Android and enable the Python interpreter. Then copy over the Python and config files to the SD card and script away.
  
  
  

We hope this gives developers, hobbyists, and students a head start in connecting the next generation of cloud apps to the world of robotics. Be sure to push your mobile phone’s processor to its limits and share the results with the Cellbots Google Group. Try using Willow Garage’s OpenCV for Android or the new Gingerbread APIs for gyroscopes, enhanced OpenGL graphics, and multiple cameras!

Seo Master present to you: By Sean Owen, Google Print Ads Team

Recently in the New York Times, we placed a small graphic as part of a Google Print Ad. You aren't looking at one of those eye focus games (It's a sailboat! Or a shark!) but a two-dimensional barcode. Those of us who already know what it is pulled out our phones and "clicked" it with the camera, and were connected to the advertiser's web site. "Wha?", you say? See http://www.google.com/printads/barcode. While this kind of thing has been a common sight in Asia for years, this ad is one of many signs that the technology is arriving in Europe and North America.

But Advertising is only part of the story here. Engineering is also involved and we want to improve the quality and availability of barcode reader software available to developers and end users. So today I would like to announce the "ZXing" (from: "zebra crossing") project, an open-source, Java, multi-format 1D/2D barcode reader which can be built into a reader application for Java and Java ME -- and later, Android.

This project began as a 20% project and is not yet complete, so opening it up is a bit of an experiment. It's not yet the Best Barcode Reader Ever, but it's looking pretty good. For now we want to find those those who can make use of and help improve what's here, so that those good ideas are shared to all developers and everybody wins.

Developers can find the ZXing project on Google Code, and we hope you'll join us on our Google Group and tell us about what you like and don't like about the code.2013, By: Seo Master

Seo Master present to you: I'm excited to announce the Issue Tracker Data API for Project Hosting on Google Code! The Issue Tracker Data API is a Google Data API that you can use to programmatically add new issues, make changes to existing issues, or simply access issues for your open source project.

This means that the issue tracker data for your open source code is now liberated!

To get started with the API, please refer to the following documentation:

• Issue Tracker Data API Overview


• Issue Tracker Data API for Java


• Issue Tracker Data API for Python


• Issue Tracker Data API Reference

If you find yourself digging into the API and creating something useful that others can use, please let us know and we'll be sure to add it to our documentation. As always, your feedback is also welcome.

The team would also like to thank Joe LaPenna, who contributed the Python client for the Issue Tracker Data API in his 20% time.

Seo Master present to you: By Michael Kerrisk, Software Engineering Team

As you may know,Google allows its engineers to spend 20% of their time on projects independent of their regular day to day job. For my 20% time, I chose to continue and expand my work on maintaining the Linux man-pages.

Since April, we've managed to ship 21 new releases, with a dozen or so new pages, and around 400 major and minor improvements to existing pages.

My work on the Linux Man-pages project man-pages led me to talk about kernel-userland interface design, testing, and documentation at the recent LinuxConf Europe, where my Zurich colleague Roman Marxer also spoke about Google's recently open-sourced Ganeti virtual server management software.

I was lucky enough to be invited to the immediately following USENIX Linux Kernel Developers Summit, where I joined Google colleagues Andrew Morton, Paul Menage, and Martin Bligh to participate in the discussion of current topics related to kernel development, including the topic of kernel-userland API design, testing, and documentation.

You can read my talk, and in-depth coverage of the Kernel Developer Summit at LWN.net. It's available to LWN.net subscribers only until the 20th of September, but you can already see the obligatory group photo.
