6. Spending Money
• All expenditures are handled via public
voting
• What have we spent money on?
• Team Meetings
• Conferences
• Audio/Video Equipment
• Contract for Scott to do UI dev

7. Spending Money
• What will we be spending money on?
• Improving server infrastructure
• Getting more developer time to train and
mentor new developers
• Design work and jQuery Mobile
• More team meetings and conferences

8. Governance Rules
• We’re in the process of finalizing some
formal governance rules for the project
• This will set very clear guidelines on how
finances can be used, votes held, and new
members joining the project

9. Path to Contribution
• We’re actively working on a new set of
public documents describing how to
contribute
• Also setting up dedicated teams to help
review and mentor new developers
• We want a constant, fresh, influx of new
developers to the project!

10. Legal
• Working with the Software Freedom Law
Center
• We’re in the final steps of transferring
copyright of Packt’s ‘Learning jQuery 1.4’ to
the project.

11. CLAs
• We’ve finalized a CLA process for jQuery
• We’re getting the full jQuery team to sign
and all major contributors
• The project will hold the rights to the code
base and have certain patent assurances as
well

12. jQuery Store
• We’re starting to sell jQuery t-shirts today
on the new jQuery store:
• http://store.jquery.org/

13. New Releases
• jQuery 1.4.3
• Official Plugins:
• jQuery Templating
• jQuery Data Linking
• jQuery Mobile

14. jQuery 1.4.3
• JSLint
• Modularity
• CSS
• Traversal Performance

15. JSLint
• Tool written by Douglas Crockford
• Do some basic validity checks on JavaScript
• With more commits coming in, helps to
enforce basic style guidelines
• Completely integrated into our
development workflow: make lint

16. Modularity
• All jQuery modules can now be individually
loaded.
• Could use a script loader to load each file
separately.
• Allows us to avoid building jQuery to run
the test suite.

17. CSS
• Massive rewrite of the CSS module.
• Focus on extensibility.
• (A bit of performance too!)
• Plugins already using it: jQuery Rotate

24. Data Linking
• Sync forms live with JavaScript objects.
• Dramatically simplify the process of
extracting data from a form and updating it.

with devs at Microsoft.
• http://github.com/jquery/jquery-datalink

27. Templating
• New official templating plugin.
• Provide a simple way of putting data into an
HTML string.
• Developed in conjunction with devs at
Microsoft.

30. jQuery Mobile

31. The Missing Gap
• Almost all mobile web development
focuses on modern WebKit
• There are far too many other platforms
• Blackberry, Opera, Windows Mobile,
Mobile Firefox, Symbian, etc.
• jQuery Mobile works everywhere - and
without sacrificing experience.

34. Phase 1: jQuery Core
• We’re working to make jQuery core work
on all the popular mobile browsers.
• Building out our test suite and continuous
integration testing.
• Using TestSwarm to automate our testing
across all platforms.
• Fixing mobile bugs in core.

36. Phase 2: jQuery Mobile
• A complete framework for building mobile
web sites and applications.
• Provide all the widgets and layout
components necessary to build mobile
sites.
• Built on the principles of progressive
enhancement
