intuitive - future computing...

If you think of lenovo thinkpad  or  apple products, you see that people pay premium for the last mile to gain intuitive.

For thinkpad:  the thinkvantage is making finger-print so useful. My experience of FP with Dell is so horrible, that I almost think that it is a bad idea. Thank god that Lenovo changed the wrong perception.

Dell:  finger-print for login only. It takes almost dozen steps before it is setup for fingerprint login. Then the whole process is so awkward, that I hate my login screen. Not mention that it takes so long to login with finger print, almost totally defeat the purpose of FP - simple, convenient and speed-up process.....

With Lenovo, you just need to:
1. run fingerprint from ThinkVantage (button);  done with fingerprint!!
2. a client security solution created a hard-ware supported "password vault".
if some 3rd party messed with your ThinkVantage, re-install TPM

smartphone market 5/2009

- The iPhone OS had 8% of the smartphone market, but generated 43% of mobile Web requests and 65 percent of HTML usage.

- The Android OS share of the smartphone market was less than 1%, but generated 3% of mobile Web requests and 9% of HTML usage.

- The Symbian OS had 52% of the smartphone market, but generated only 36% of mobile Web usage and 7% of HTML usage.

- Usage of mobile Web sites greatly out paces usage of HTML sites on smartphones running the Symbian and RIM Operating System (OS).

- 24% of US requests were made over a Wi-Fi network. The top five Wi-Fi devices in terms of usage were the iPhone, iPod touch, Sony PSP, HTC Dream (G1), and HTC Dash.

Bayeux protocol data structure

wls pubsub server

 IT trends 2010 series (2)

com.bea.httppubsub.BayeuxMessage

Develop steps

1. weblogic.xml library-ref
   
2. weblogic-pubsub.xml  (weblogic-pubsub.xsd)
   
   

3. PubSub API for publish, filter, dynamic channel (optional)
   lookup pubsub server & create local client
           publish to channel
           subscribe (listener register)
           filter chain (filter class, config chain)
   APIS:
           com.bea.httppubsub.PubSubServer
           LocalClient
           ClientManager
           MessageFilter
           DeliveredMessageListener
           BayeuxMessage
   
4. Add Dojo to jsp/html for publish/subscribe msg.
   //Initialize the Dojo cometd environment
   dojo.io.cometd.init({}, "/context/cometd");
       cometd - matching default pubsub war web.xml
   
   //Publish a message to a channel
   dojo.io.cometd.publish("/a/channel", "message content");   //publish text msg
   dojo.io.cometd.publish("/a/channel", {"data": "content"}); // JSON object
   
   //Subscribe to a channe
   dojo.io.cometd.subscribe("/a/channel", null, "onUpdate");
   
           //JS function for call back
           function onUpdate(message) {
             if (!message.data) {
               alert("bad message format "+message);
                 return;
             }
             // fetch the data published by other clients
             var data = message.data;
           }
5. Deploy web-app; pubsub war library  WL_HOME/common/deployable-libraries
   
6. Other aspects
   
   
   • Persistent Channelsweblogic-pubsub.xml  persistent-client-timeout-secs
     

   • JMS as provider for cluster support weblogic-pubsub.xml
     
     

            t3://localhost:7001
            ConnectionFactoryJNDI
            TopicJNDI

   • Requiring SSL for pub-sub Via web.xml INTEGRAL
     
   • AuthCookieEnabled to Access SSL resources
_WL_AUTHCOOKIE_JSESSIONID created (cookie or URL rewrite). This is default behavior
     
   •  Locking Down the Pub-Sub Server (5-*)
     
   *Configure SSL for pub-sub.
   *Require authentication (BASIC, FORM, and so forth.)
   *Ensure auth-cookie is enabled.
   *Ensure that all the channels are constrained in the weblogic-pubsub.xml file.
   *Lock subscribe operations, which are allowed by default.
   

AJAX - technology

 IT trends 2010 series (1)

AJAX - Async-JavaScripts and XML

Web development that uses JSON or XML for data exchange,  DOM.XMLHttpRequest for protocol access,  JavaScript for operations, and HTML/CSS for display.

Competing technologies: Java Applet / Web start,  Flash,  ActiveX

Technology selection:

framework: DOJO, GWT, ADF

push: CometD, IceFace

server support: GWT, WLS pub/sub server

Usability
      Use Ajax, a page can be created by tiles, and reload only the part that's changing. This and async interaction with server also enhances usability. Meanwhile, page states is maintained within js.

1. suggestion while typing
   
2. loading partial changed tile
3. responsive - e.g: pre-factch data
   
4. ajax push
5. offline(?)
6. visual - virtual reality
   

Drawback
      There may be more frequent requests to server. Dynamic page updates causes browser bookmar, history buttons and search engine difficulties. Other issues including security and development efforts.

• Scripting language - language augment a system/GUI to achieve automation by non-experts.
•  Client side enabling for RIA application
  
• JSON - javascript and ECMA scripts
  

Ajax Push
       Push framework using Ajax, has a set of technologies supporting it. Bayeux protocol, implemented as CometD, from DOJO.
 

Ajax Framework includes: DOJO, ADF, Google web toolkit, iceFace, MooTools/Ape, Yahoo UI library, jQuery

cloud computing

If SaaS, PaaS, IaaS is to benefit a company, the scale of economy has to take into play. For a large enterprise, for example, WalMart, it's IT infrastructure is so huge and so big, it just make sense to have its own private cloud. It is not imaginable for a company as big as GE to outsource it's infrastructure to Google.

The shared services will provide scale of economy by its own IT.

If google or others hosting this for them, it might just cost too much for the service.

Private cloud for small and medium business may not make much sense, they can use Google for scale of economy. But as the company grow, the steady flow of cash toward google might have to be stopped. 

Cloud computing - outsource part of IT

Why?

• Reduce IT, focus on core
• Fast/cheap IT
• Expertises
  

While maintain IT for competitve edge and customization.



Clouding computing:

salesforce.com - SaaS
amazon.com


google appengine - PaaS (limited)
azure
rackspace managed hostings - IaaS

Computer 2068

Will the computer in the year of 2068 be able to perform "creative work"?

To answer this question, we have to clarify the following:
1. What considered "creative"?
2. How to judge the results?

If a computer can evolve itself from a certain "start point", and can self-improve over time/space, then it is creative. Here "self-improve" need to be clarified as "creative".

1. What is self-improve?
2. Is it objective?

For a computer, self-improve is result satisfying the following:
1. Same job faster
2. Same job with less less resources consumption
3. Add new capabilities
4. New solutions that satisfy one or all criteria above: 1-2-3

If all these happens, a computer will be able to invent, and thus, substitute human thinking!


Here is how:

Over the process, the computer will be "smarter" by acquire new capabilities, be "more efficient" by consume less resources, be it energy or space or raw material, and in the same time, provide new solutions, new creation, and make the world a better place to live...
