If you’ll be in the San Francisco area during JavaOne week, and you’re interesting in attending some of JavaOne, but don’t want to pay for the entire conference, consider purchasing a JavaOne / Oracle Develop Discover pass. The base Discover pass costs just $75 and provides you with entry into the keynote addresses, the exhibition halls, the Mason Street Tent (where I’ll be spending quite a lot of time), Oracle Mix, and more. If you’d like to attend a few sessions, consider the Discover Plus pass, which provides your choice of three OpenWorld or JavaOne / Oracle Develop sessions and some other extras, for $695.

Note that these prices are the pre-conference prices — you need to purchase your Discover pass by September 18 to get these rates. If you purchase your pass at the conference, the cost will be $125 for the Discover pass, and $795 for the Discover Plus pass.

The Mason Street Tent will be in part a gathering center for the Java community. As java.net Community Manager Sonya Barry recently reported, the tent will be the center of java.net activity at JavaOne. Though I’ll be attending quite a lot of sessions, when I’m not attending a session, you’ll usually find me in the tent (probably writing a blog about the last session I attended, or chatting with the community, or writing a blog about one of those chats). Java User Group leaders are expected to be setting up shop near the java.net area, and the Oracle Technology Network will also be in the area. The OTN will be featuring a full schedule of interviews and talks with key members of the Java and broader open source communities as part of its Oracle Technology Network Live program.

You can get a sneak preview of JavaOne, including what’s going to be in the tent, this coming Tuesday, September 7, at 10 AM, Pacific Time, in a special edition of Justin Kestelyn’s TechCast Live. See the details in the JavaOne Conference Blog’s post JavaOne Preview on TechCast Live! (Tues., Sept. 7, 10am PT).

Still having doubts? Well, as Sonya notes, java.net will be located right next to the coffee and beer — so that should guarantee we’ll see you, right?

But, seriously, if you’d like to attend just some of JavaOne, do consider purchasing a JavaOne / Oracle Develop Discover pass. With everything that’s going to be going on in the tent, in the exhibition halls, and at the keynotes, how can you go wrong for just $75 (or $695 to be able to attend 3 sessions)?

Java Today

In the Aquarium, Alexis Moussine-Pouchkine announces a New GlassFish 3.1 Screencast: Application-scoped resources:

This short screencast demonstrates the new application-scoped resources feature available starting with Milestone 4 of GlassFish 3.1 (the demo used promoted build #17). Such resources are bound to a module (war, ear, ejb) and as such they are created on deploy and destroyed when the module is undeployed. They are defined in a file called glassfish-resources.xml (schema-constrained) and shipped with the archive…

At Hudson Labs, Kohsuke Kawaguchi talks about Recent label and matrix project improvement:

Today, I?d highlight two recent improvements to the label and matrix projects. When you have multiple slaves in your Hudson build farm, you can use labels to classify slaves by their capability/environment/architecture/etc. For example, your one slave might have ?32bit? and ?windows? label, while another one might have ?linux?, ?ubuntu?, and ?64bit.? (with plugins like platform-labeler plugin, you can attach labels automatically, too.) Or if you do Selenium testing, you might add browser names as labels to indicate which slave has which browser available…

Robilad announces the availability of JVM Language Summit 2010 Recordings On Oracle Media Network:

The recordings of the majority of the sessions from the JVM Language Summit 2010 have been uploaded to the Oracle Media Network. Paul Leahy has compiled a list of session recordings and their corresponding abstracts. Slide decks for most of the sessions are available on the JVM Language Summit wiki…

James Sugrue reports on Eclipse innovations in IDE 2.0: The Age of Intelligent IDEs -

The latest innovation in the Eclipse space that I’d like to share with you is Code Recommenders. Already available as a plugin for Eclipse, Code Recommenders provides intelligent code completion. Rather than giving you all possible methods for code completion, this plugin proposes the methods that you probably need at the top of the list, with a rating of how applicable each method is. To see Code Recommenders in action, see the following screencast…

Poll

Our current java.net poll asks What threat does further fragmentation of the Java language pose? Voting will be open until Monday.

Spotlights

Our new java.net Spotlight is from the JavaOne Conference Blog, JavaOne Preview on TechCast Live! (Tues., Sept. 7, 10am PT):

You’ve read the blogs, you’ve consumed the tweets and Facebook updates. Now how about hearing from some live humans? Next Tuesday morning (Sept. 7, 10am PT), Oracle Technology Network offers you a JavaOne preview via a live video chat with Sharat Chandar and Tori Wieldt, two people intimately familiar with the content and community aspects of the conference. You’ll get insights into the content contribution process, hear about particularly interesting technical sessions and BOFs, and get a sneak peek of the contents of the Mason St. tent, where Oracle Technology Network will host the community in all its glory…

We’re also still highlighting java.net Community Manager Sonya Barry’s JavaOne Conference Blog post Java.net Activities at JavaOne:

I’m excited about JavaOne this year.  It’s going to be different in a lot of ways, but we are doing our best to ensure that the Java.net presence for the community is just as good if not better then previous years.  In years past Java.net has had a “community corner” booth in the JavaOne pavilion at Moscone… This time we’ll be housed in the Mason Street tent, which will be a large comfortable space for people from all of the technology communities to hang out, pick up swag, watch the videocasts, and see some live events too..,

RailsTutorial.org

To learn Rails from scratch Michael Hartl recently finished his book Ruby on Rails Tutorial: Learn Rails by Example. The book teaches Rails 3 from the ground up and it?s available for FREE online. If you?d rather have a PDF or a book you can grab that as well (and he?s even working on some screencasts).

The source for the finalized book will be pushed to GitHub and released under a Creative Commons License shortly after Rails 3 is done. If you?d like to help translate the book to your language of choice, feel free to contact Michael and he?ll get in touch when it?s time to make it happen.

Rails Guides

If you?re not a Rails newbie don?t forget about the Rails Guides, which have been updated for Rails 3.

Rails API Docs

There are two main websites I use to do API lookups. The first is Rails Searchable API Doc, which has online and offline searchable documentation. The second is APIdock which is online only, but has the ability to comment and easily compare different versions of documentation.

Rails 3 Free Screencasts

If you?re more of a visual learner (like me) then there are plenty of free screencasts to teach you about Rails 3. About 2 months ago I produced the Rails 3 Screencasts, which will get you started.

Ryan Bates has also produced an incredible amount of Rails 3 screencasts over on Railscasts.com. Ryan has been producing Railscasts for over 3 1/2 years, isn?t that crazy?

There?s also a few good free screencasts over on Teach me to Code by Charles Max Wood.

Keeping on the Edge

If you find yourself wondering how to keep up with all of the newest features / libraries for Rails 3, both the Ruby5 Podcast and the Ruby Show are going strong. Don?t listen to audio? It doesn?t matter, just subscribe to the Ruby5 RSS feed and get links with descriptions to all the newest libraries, tutorials, and more. You might also want to checkout Peter Cooper?s new Ruby Weekly, a Ruby email newsletter

.

Need to upgrade a big app to Rails 3?

Jeremy McAnnaly?s Rails 3 Upgrade Handbook PDF is just $12. There?s also a few paid screencasts for the upgrade over on Thinkcode.tv and BDDCasts.

Need a Book?

There?s a bunch of books that will be coming out after the release, most of which you can start reading now. The Rails 3 Way by Obie Fernandez, Rails 3 In Action by Ryan Bigg and Yehuda Katz, Beginning Rails by Cloves Carneiro Jr and Rida Al Barazi, and of course the Agile Web Development with Rails:fourth edition by Sam Ruby, Dave Thomas, and David Heinemeier Hansson.

In conclusion

No more complaining about lack of good documentation! Seriously. If you want even more Rails 3 content, check out the blog post by Kevin Faustino on 34 Ruby on Rails 3 resources to get you started.

Max Lifshin, an Android developer living in Russia, says his Tap Snake program is not a Trojan or virus, despite a warning from security software maker Symantec last week. Lifshin has been vilified in the press for releasing the program, which was intended for parents to track their children?s whereabouts. Reached by ZDNet for comment, Lifshin insisted that his motivations were innocent:

The app is no more malicious than a motion detection camera – everything depends on the user?s intentions. It gives all the proper warnings and requires a set up, a conscious action, to report location. It can be easily used by mothers worrying about their kids? whereabouts. In fact, I suspect the majority of users were indeed the mothers.

For the program to work, the parent or guardian downloads and installs the innocuous looking game on their kid?s phone. During the installation process, Android asks for permission to access location information and to send and receive information to the Internet. After accepting these terms, the parent must open up a menu option and activate the tracking service with a unique key. Then they give the phone back to their child. From that point on, the game will occasionally upload its location to a server, where only somebody with the key can view it. Lifshin says:

The app is not really very different from Google?s Latitude. As any technology product, it can be put to either noble or malicious ends.

The game can be uninstalled at any time. The program run by the parent to view location information is called GPS Spy. The Market description for GPS Spy openly explained how all this works, saying:

Download and install the free Tap Snake game from the Market to the phone you want to spy on. Press MENU and register the Snake with the service. Use the GPS Spy app on your phone with the same email/code to track the location of the other phone.

However, the description of the Tap Snake game did not say anything about tracking, presumably so your child could look up the game for updates or reviews and be none the wiser. Until recently, Tap Snake was a free download and GPS Spy was $4.99. After the news came out, Google removed both apps from the Market. According to Lifshin,

What?s sad is that these ?whistle blowers? have prompted Google to suspend the app and thus deprived me of income. They unfairly classified this app as a Trojan and portrayed me as a villain, a malicious Russian developer working in the shadows.

What do you think: is this a dangerous Trojan or a useful safety device for parents? Was Google right to ban it? Speak up in the Talkback section below.
