The Croquet architecture supports synchronous communication, collaboration, resource sharing and computation among large numbers of users on multiple platforms and multiple devices.

Nothing like a framework to ease your burden.  Check it out, more than 50 java development frameworks are described and linked.  Of course the usual suspects are here: Cocoon, Struts, and Java Server Faces.  But also includes Tapestry, RSF, ZK and JAT.  Wow, glad we are finally moving into this space...

A useful and small javascript library for select box functions.

From the website:

RSF is an open source web programming framework, with roughly the scope of Sun's JSF. RSF is written in Java, and is built on the Spring framework. RSF features a pure-HTML templating engine named IKAT, which achieves the cleanest separation between presentation and logic yet made - build "components" using pure HTML and libraries of code rather than heavy framework base classes. RSF also features a lightweight request-scope Spring clone, RSAC, which brings the magic benefits of inversion of control into the request scope. RSF currently has integrations for Hibernate, JSR-168, Cocoon and Sakai

This could be a good model for us since it is a very very clean separation of logic from layout. Makes widgets available to <div> containers in XHTML.

More tools...

While writing this blog a small library of reusable components based on YUI has been started. The library was namespaced YAHOO.ext (short for Yahoo! UI extensions), and already has a few very useful classes that make day to day development with YUI much easier. All of the classes are well-documented and there are some examples of using them found in the posts on this blog. The code is of course free and has the same unrestrictive (BSD) license as Yahoo! UI.

It's all about tools, baby...

The Yahoo! User Interface (YUI) Library is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, DHTML and AJAX. The YUI Library also includes several core CSS resources. All components in the YUI Library have been released as open source under a BSD license and are free for all uses.

I got to love a manifesto.  Especially one that pushes for a different model of programming that works the way I think we need to work.  We are small, we are pulled in many ways, we are challenged, we are overworked...  We need to try this more formally.

Great set of javascript / ajax widgets that includes image side-by-side viewers. 

Cookie based web authentication and single sign on system designed for largish intranets under a single domain where many people run their own webservers (and you don't trust them all much).

On first connection, an untrusted webserver redirects new requests for restricted pages to the idcheck server (to be authenticated). The idcheck server takes and checks the users credentials and, if successful, redirects the users browser back to the page they requested. As it redirects, the server installs a private cookie (scoped only for the idcheck webserver) and a second cookie that acts as a session cookie for the untrusted webserver (which is checked for validity, over http against the idcheck server) when downloading subsequent pages.

When the user accesses another webserver that also has idcheck restricted pages he does not need to enter his credentials again because of the private idcheck cookie indicates that he has already authenticated and so can bypass the login form. This provides a single sign on environment for multiple webservers in a single domain..

Catalyst is an elegant web application framework, extremely flexible yet extremely simple. It's similar to Ruby on Rails, Spring (Java), and Maypole, upon which it was originally based.

MVC

Catalyst follows the Model-View-Controller (MVC) design pattern, allowing you to easily separate concerns, like content, presentation, and flow control, into separate modules. This separation allows you to modify code that handles one concern without affecting code that handles the others. Catalyst promotes the re-use of existing Perl modules that already handle common web application concerns well.

Here's how the M, V, and C map to those concerns, with examples of well-known Perl modules you may want to use for each.

• Model

  Access and modify content (data). DBIx::Class, Class::DBI, Plucene, Net::LDAP...

• View

  Present content to the user. Template Toolkit, Mason, HTML::Template...

• Controller

  Control the whole request phase, check parameters, dispatch actions, flow control. Catalyst itself!

If you're unfamiliar with MVC and design patterns, you may want to check out the original book on the subject, Design Patterns, by Gamma, Helm, Johnson, and Vlissides, also known as the Gang of Four (GoF). Many, many web application frameworks are based on MVC, including all those listed above.

The Inmates Are Running the Asylum, published in 1998, introduced the use of personas as a practical interaction design tool. Based on the single-chapter discussion in that book, personas rapidly gained popularity in the software industry due to their unusual power and effectiveness. Had personas been developed in the laboratory, the full story of how they came to be would have been published long ago, but since their use developed over many years in both my practice as a software inventor and architectural consultant and the consulting work of Cooper designers, that is not the case. Since Inmates was published, many people have asked for the history of Cooper personas, and here it is.

Good site on programming with ajax. Lots of examples and good code library to use. I like this site since it cuts thru the evangelical zealotry of many ajax sites and gives the good, the bad, and the ugly...

I love lists!  Here's a nice list of how to program.

1. Do not expect a detailed specification.
2. Do not spend your time polishing a detailed design.
3. Keep your eyes on the real problem.
4. Have a team of smart guys.
5. Keep the complexity of your decisions down.
6. Do not optimize your code without solid reliable data.
7. Do not code "till it's done".
8. Start debugging while designing.
9. Do not flatter yourself that your system is bug-free.
10. Do not expect to create a perfect documentation.

 

The OAICat Open Source Software (OSS) project is a Java Servlet web application providing a repository framework that conforms to the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) v2.0. This framework can be customized to work with arbitrary data repositories by implementing some Java interfaces. Demonstration implementations of these interfaces are included in the webapp distribution.

Site with tutorials on xmlhttprequest, drag and drop, forms, uploaders, image gallery, live search, and tabbed pages.

A must page. 

Great site for figuring out cross-browser scripting.  Excellent tutorials and explainations of browser support and work-arounds for JS script functions.

suave!!!

Mozilla developer center tutorials on AJAX.  Solid background site.

Good test tool for JS

CGI::Ajax is an object-oriented module that provides a unique mechanism for using perl code asynchronously from javascript- enhanced HTML pages. CGI::Ajax unburdens the user from having to write extensive javascript, except for associating an exported method with a document-defined event (such as onClick, onKeyUp, etc). CGI::Ajax also mixes well with HTML containing more complex javascript.

CGI::Ajax supports methods that return single results or multiple results to the web page, and supports returning values to multiple DIV elements on the HTML page.

Using CGI::Ajax, the URL for the HTTP GET/POST request is automatically generated based on HTML layout and events, and the page is then dynamically updated with the output from the perl function. Additionally, CGI::Ajax supports mapping URL's to a CGI::Ajax function name, so you can separate your code processing over multiple scripts.

Other than using the Class::Accessor module to generate CGI::Ajax' accessor methods, CGI::Ajax is completely self-contained - it does not require you to install a larger package or a full Content Management System, etc.

We have added support for other CGI handler/decoder modules, like the CGI::Simple manpage or the CGI::Minimal manpage, but we can't test these since we run mod_perl2 only here. CGI::Ajax checks to see if a header() method is available to the CGI object, and then uses it. If method() isn't available, it creates it's own minimal header.

A primary goal of CGI::Ajax is to keep the module streamlined and maximally flexible. We are trying to keep the generated javascript code to a minimum, but still provide users with a variety of methods for deploying CGI::Ajax. And VERY little user javascript.

Article about reading bookmarks with ajax.  Also good links to other ajax resources...

This module generates SAX events from SQL queries against a DBI connection.

Great tips on CSS, AJAX and other Web 2.0 thingies...

24 things refers to 24 things to do that will impress your friends. Things like:

A whole ezine dedicated to AJAX.  Cool!

A collection of resources that support use of AJAX to create web pages and services that improve user experience.

This example demonstrates a simple AJAX javascript for requesting XML data from a server and displaying the response in a HTML-table. The server-side script is a simple PHP script, which actually just sends some XML data.

xISBN supplies ISBNs associated with individual intellectual works represented in the OCLC WorldCat database. Give it an ISBN, and it returns a list of associated ISBNs.

To be used by a program to return an XML document of all the associated ISBNs for a title.  Sort of like what I do for journal titles using SFX to return ISSNs. 

COinS (ContextObjects in Spans) is a simple, ad hoc community specification for publishing OpenURL references in HTML.

We should think about how to embed these in our pages... 

Article on how to build a SOAP server with perl.

The use utf8 pragma tells the Perl parser to allow UTF-8 in the program text in the current lexical scope (allow UTF-EBCDIC on EBCDIC based platforms). The no utf8 pragma tells Perl to switch back to treating the source text as literal bytes in the current lexical scope.

Calendar::Schedule - for managing calendar schedules

This module is an interface to the gnome project's libxslt. This is an extremely good XSLT engine, highly compliant and also very fast. I have tests showing this to be more than twice as fast as Sablotron.

I very good site for javascript programming.
