Visual weight of primary and secondary action buttons

Pretty interesting observation on why the irreversible, permanent action should become the secondary button:

Heap profiling on chrome

Neat: http://code.google.com/chrome/devtools/docs/heap-profiling.html
It's becoming more important when you move to resource limited devices, such as pads and phones.

AS7 Console performance improvements

I did take a look at the components that serve the console files again and removed some really sloppy parts and tweaked the HTTP cache behavior a little bit. With some really interesting results.

This is what the average page loading time looked like, when client did access the console for the first time:



This is what looks like after the improvements:



It get's even better, when a client does access the console subsequently:



How can it be explained?

Well the most notable improvement is probably the replacement of the sloppy IO parts. Hence the drastic page loading times from ~4sec to ~1sec. Furthermore the addition of an HTTP "Expires" header allows the browser to successfully cache the results, which drastically decreases the page loading size from ~750kb ~10kb. All tests have been run on a LAN connection.

Managing JBoss7: Console Beta9 released

We just updated to 1.0.0.Beta9:
===================

- suport for standalone
- i18n
- deployments
- authentication

- datasources
- jms configurations
- messaging
- web subsystem

- server groups
- server configurations

- system properties
- jvm options
- socket bindings


The given functionality has small glitches here and there but most of it has been reported and is being worked on. In terms real tasks, this is still outstanding:

- transaction subsystem
- security
- webservices
- threads
- logging

But we expect this to be ready for 7.0.CR1.

Give it try & let us know what you think.
Tell us what works and what doesn't.

How do I access the console?
==================

http://localhost:9990/console



How do I enable authentication?
====================

Simply create a security realm configuration.
This needs to be done in "domain/configuration/host.xml" for domain mode:

<management>
       <security-realms>
           <security-realm name="ManagementRealm">
               <authentication>
                   <users>
                       <user username="admin">
                           <password>
                               password
                           </password>
                       </user>
                   </users>
               </authentication>
           </security-realm>
       </security-realms>
   </management>
   <management-interfaces>
       <native-interface interface="public" port="9999"/>
       <http-interface interface="public" 
            port="9990" security-realm="ManagementRealm"/>
   </management-interfaces>

Or "standalone/configuration/standalone.xml":

<management>
       <security-realms>
           <security-realm name="ManagementRealm">
               <authentication>
                   <users>
                       <user username="admin">
                           <password>password</password>
                       </user>
                   </users>
               </authentication>
           </security-realm>
       </security-realms>
   </management>

   <management-interfaces>
      <native-interface interface="default" port="9999"/>
      <http-interface interface="default" 
              port="9990" security-realm="ManagementRealm"/>
   </management-interfaces>

How do I switch between standalone and domain administration?
========================================

Just boot AS7 in either one of these modes and reload the console web application.

WebKit Remote Debugging

Interesting, remotely connect the web inspector to a web kit instance:
