LLOOGG, a service that lets you check who is visiting your site in real time: which pages are being visited, with which operating system and browser, the referrer of each visit

You can have a look at a demo of the service from here, it has been open to public recently and it is developed by an Italian company, Merzia.

Everything that is posted on del.icio.us is viewable by the public, although you can choose to make specific bookmarks private. Bookmarks are publicly viewable for a purpose. Many people use del.icio.us to publish links to their personal or business blogs. You can use the del.icio.us interface to keep links to your favorite articles, blogs, music etc. You can also share your favorites with anyone who has an e-mail address. del.icio.us also has a search function that allows you to explore what others are book marking, and find other websites that are related to your interests.

We didn’t do either because they were cool, or for any desire to be some sort of fashionable IT software company. We did it because it makes sense for our users, and both are an approach to building more affordable, useful, and scalable IT.

Open source is a business model for us to work with our users - they are building modern web-driven applications and need better monitoring and management for these dynamic, custom-built environments. Since they are web-afficianados when they have a problem they consult, that’s right - the web. They do a Google search, they look for how others solved it - and they look for the straightest line to applying the same solutions to their unique situation. They want self-service. They want quick results. Open source lets them download and use the software without unneccesary limits on time, scale or its application. Once our software establishes its value, if there is more opportunity to help them more, we have an educated, successful, in-house champion to help work through the sale. We save a lot on the cost of sales and support this way. The customers in turn save time and money in completing their solution. Open source is way to package our products and services to ease adoption so everyone benefits.

I descibed my first "helloworld component for joomla 1.5 in my previous tutorial hello world component for joomla 1.5 I have got a huge response for joomla developers and I believe some of them were right pointing out that helloworld should be rewritten to MVC model.

This is very brief introduction. Please refer to these links for thorough explanation.
MVC on wikipedia
The Model-View-Controller (MVC) Design Pattern for PHP by Tony Marston
developers joomla1.5 forum

MVC - model view controller

MVC is an architectural pattern used in software engineering. In complex computer applications that present lots of data to the user, one often wishes to separate data (model) and user interface (view) concerns, so that changes to the user interface do not impact the data handling, and that the data can be reorganized without changing the user interface. The model-view-controller solves this problem by decoupling data access and business logic from data presentation and user interaction, by introducing an intermediate component: the controller.

After researching various articles on the internet I came up with the following descriptions of the principles of the Model-View-Controller design pattern:

The MVC paradigm is a way of breaking an application, or even just a piece of an application's interface, into three parts: the model, the view, and the controller.

MVC was originally developed to map the traditional input, processing, output roles into the GUI realm:

Input --> Processing --> Output
Controller --> Model --> View

Model

The model is the part of the component that encapsulates the application's data. It will often provide routines to manage and manipulate this data in a meaningful way in addition to routines that retrieve the data from the model. In our case, the model will contain methods to add, remove and update information about the books in the database. It will also contain methods to retrieve the list of books from the database. In general, the underlying data access technique should be encapsulated in the model. In this way, if an application is to be moved from a system that utilizes a flat file to store its information to a system that uses a database, the model is the only element that needs to be changed, not the view or the controller.

View

The view is the part of the component that is used to render the data from the model in a manner that is suitable for interaction. For a web-based application, the view would generally be an HTML page that is returned to the data. The view pulls data from the model (which is passed to it from the controller) and feeds the data into a template which is populated and presented to the user. The view does not cause the data to be modified in any way, it only displays data retrieved from the model.

Controller

The controller is responsible for responding to user actions. In the case of a web application, a user action is a page request. The controller will determine what request is being made by the user and respond appropriately by triggering the model to manipulate the data appropriately and passing the model into the view. The controller does not display the data in the model, it only triggers methods in the model which modify the data.

Joomla! MVC Implementation

In Joomla!, the MVC pattern is implemented using three classes:

1. JModel
2. JView
3. and JController

            en-GB.com_helloworld.ini    - (english text package)

b) concept

We need to rewrite the core of our previous component. It prints "hello world" by accessing methods of class helloScreens in admin.helloworld.html.php

 class helloScreens
 {
  function helloworld()
    { echo JText::_('helloworld'); }

  function helloagain()
    { echo JText::_('helloagain'); }

  function hellotestfoo()
    { echo JText::_('hellotestfoo'); }

  function hellodefault()
    { echo JText::_('hellodefault'); }
 }

All these methods will become stand-alone views. \views\helloworld\view.php

 class HelloWorldComponentView extends JView
 {

	function display()
	{
	 echo JText::_('helloworld');
	}
 }

As you can see there is no model instance passing into the view or accessing from the view. Unfortunatelly, there is a minor bug in joomla1.5 beta that prevents us from executing our sql script in the installation process. We can get around this problem by installing jomla 1.5 "night build" and I will show you how in the next joomla tutorial.

But Richard Stallman, founder of the Free Software Foundation and creator of the computer operating system GNU, said that cloud computing was simply a trap aimed at forcing more people to buy into locked, proprietary systems that would cost them more and more over time.

"It's stupidity. It's worse than stupidity: it's a marketing hype campaign," he told The Guardian.

"Somebody is saying this is inevitable – and whenever you hear somebody saying that, it's very likely to be a set of businesses campaigning to make it true."

...

"One reason you should not use web applications to do your computing is that you lose control," he said. "It's just as bad as using a proprietary program. Do your own computing on your own computer with your copy of a freedom-respecting program. If you use a proprietary program or somebody else's web server, you're defenceless. You're putty in the hands of whoever developed that software."

As usual, Stallman exaggerates "a bit" (but makes people think about problems): as everything else in life, the truth is in the middle. Using web services without knowing what you're doing, that's bad. But if you know the upsides as well as the downsides, then it's just a matter of choice.

The factors which we have to capture is

Hits per second,

Avg Response time,

Think Time

No of users simulated.

Thus substituting all the gathered data in the formula,

Total Number of users executed = (Response Time + Think Time) * Request per second

Note:

Thus while calulating using the formula, the result value should equal or should be greater than the total number of users executed.

From this deal we can able to find out, how much users the servers can handle. If the result value goes below the total numbers executed, then the servers are not capable to server these many users.

The Page size also can be verified using,

Page size = Throughput / Hits per second.

Today Scott Guthrie announced the RC0 release, along with some commentary on what's new in that.  The bet has to be that the final release (RTW) will be on or before PDC 2008 at the end of October.  You can get the goodies on the silverlight.net site.  Note that it's only a release for developers (using VS2008) and includes the runtime, but it's not intended for public deployment - it's a pre-RTW testing opportunity for developers.  There's also a Blend 2.0 SP1 preview to target RC0.

Anyone with the 2.0 Beta 2 or 2.0 RC0 runtimes should get an auto update to 2.0 RTW when it's available.

Only concern is whether i have internet access or not that is the concern, but in today internet access is almost like electricity, not a make concern. and i hope the believe that web or web application inside the browse will eventually take over the client/server based as it make installation and upgrade easy and not to mention deployment much much easy.

With more time to come, i think i can move away from ms word/excel as well and make use of the online alternative or offline open source alternative, so no more get lock in the ongoing upgrading pressure and push from the vendor. eventually more or less is the same, not much change on the requirement for document creation, spreadsheet, presentation, PIM, email and web browser, it just right now more choice on web and open source alternative only.

Social networking software has grown in popularity with individuals over the years and recently many companies have started to take advantage of the corporate social networking software that developers have made available. These software programs make it easy for businesses to take advantage of the social networking craze with little or no networking experience. With the help of social networking software corporations can reach their target audience in larger numbers than ever before. These different programs are designed to work with various, popular, social networking websites.

Corporate social networking software is designed to be used by professionals that are using social networks solely for business. These software programs allow corporations to promote their various products or services to casual users who have expressed an interest in their company's services. They also let businesses build mailing or contact lists so that they can send out mass communications to interested users. Many corporate social networking software programs will even promote blog feeds from outside websites keeping social network users updated on information being posted on other websites.

Corporate social networking software also gives businesses the chance to connect with other companies.  This networking can be extremely valuable especially if the company runs another website or blog that needs to be promoted. Some software programs even allow corporations to recommend specific products and services to other users on the networks. By building contacts with other businesses a company can set up profitable link exchanges or cross promotions with companies that target a similar audience.

When choosing your corporate social network software it is important that you or your marketing experts identify the needs of your business. For example, if you're primary goal is to use a social network to promote a blog then pick out a software program that will make it easy to showcase your blogs RSS feed. Also, be sure that your social networking software includes customer support. Even though must corporate social networking software programs are designed to be used by people with limited experiences it is always helpful to have support available. Purchasing a software program that allows for telephone or online customer service support will help your company get the most use out of its new program.

If you're going to create your own social networking site you will have to decide what features you want to offer on the site so that you can choose the right networking software that has those particular features built into it. There are hundreds of different features that are common social networking sites, so how do you know which ones to use and which ones not to use? The trick to picking the best social networking features for your company's networking site is to make sure that each feature you pick has a functional aspect as well as a fun aspect. You also need to keep in mind the purpose of your networking site when you're choosing the software that will give you the features that you want for your site.

For example, look at one of the most commonly found features in social networking software, the ability to post videos online. Does your networking site need that feature? If your social networking site is just an in-house site to help the members of the company get to know one another more and stay connected then you might not need to have that feature. But, if your site is designed to help clients stay in touch with their account managers or customer service reps then having a video feature on the site would allow the account mangers or customer service reps to post videos and tutorials about how to use the products that you sell, and that could be extremely helpful and beneficial for customers.

Ultimately only you can decide what the best features are for your custom social networking site and which features you really want to have but when you're buying networking website software it's better to buy software that has more features then you think you will need because you might decide later on that you need different features than the ones that you want to have now. If you buy software that already has all the additional features that you might want in the future you won't need to buy software when you want to add more features to your custom social networking site.

If you want to build a custom corporate social networking site that your company can use either for communicating with each other or communicating with customers and the corporate headquarters you're probably wondering what best social networking software is. It's actually hard to pick one brand of software that is used by businesses to build a networking site and claim it's the best one because every company has different needs, making it quite possible that every company will find a different type of business networking software suits their particular needs.

In order to pick the best social networking software for your company you need to identify what features you want your online community site to have. If you want just a basic networking site then you probably want to choose networking business software that doesn't have a lot of bells and whistles because you'd end up paying a lot more for features that you don't need. If your business networking site has to look like all the other company social networking sites that are going to be under one large company umbrella then you will have to use the same social networking software that all the other companies that do business that corporate umbrella are going to use for their sites. And if you want a custom online networking site that has all the bells and whistles that a site like MySpace has then you'll have to get top of the line corporate social networking software.

Once you have identified what type of features you want your custom social networking site to have you should try out a few different corporate social networking software packages to see what each one offers and how each one is to use. Most social networking software companies will give you a 30 or 60 day free trial of their software to make sure that the software fits your needs before they require you to buy it. Take advantage of the free trials of corporate social networking software so that you can compare different brands and see which one will give you the type of corporate social networking site that you want.

The focus for the new release of Ubuntu will be on reducing the boot time:

We want Ubuntu to boot as fast as possible - both in the standard case, and especially when it is being tailored to a specific device.

And the other goal is the integration of web application with desktop:

Another goal is the the blurring of web services and desktop applications. "Is it a deer? Is it a bunny? Or is it a weblication - a desktop application that seamlessly integrates the web!"

I'm really curious about this last goal: we'll see what Ubuntu Jaunty Jackalope will bring us!

With Retail Answers' long track record of developing web applications in .NET, I asked one of our developers what she would look for in a browser specifically designed to run web apps. And the answer? Get control of the back button. She wanted to be able to hook the code under the "back" or "previous" link on the pages she develops into the back button so that the confusion that occurs when the user goes back illegally would be avoided.

What a difference this would make to basket abandonment! How many times have you got caught in a tangle when authorising cards, finalising delivery addresses and checking the contents of the basket?

Our initial naive solution to this problem was to parse the upload file into individual records, save the record to the database and then send a JMS message containing the PK of the record to a JMS queue to kick off asynchronous processing for each record.

It worked great....until we tried to process a file with more than a few thousand records. Then the transaction that the file processing was running in started timing out. That's a problem.

You see, our benchmark for file processing is 10k records--that's the expected size of the files we will start receiving once our system goes live. We'd also like to have some additional breathing room in processing capability in case we see larger files in the wild. But, as it was, not only did we not have any breathing room, we had a giant boulder sitting on our chest crushing us.

What to do?

It was about this time that I reflected on the need for an entirely new approach, not a variation on our existing processing strategy. Spring Batch to the rescue.

The Spring Batch framework is a new addition to the Spring portfolio. The primary committers on the project have extensive experience producing batch processing solutions. It is primarily designed as a Java based batch processing framework using traditional batch processing strategies. In other words, it wasn't a natural fit for my needs: kicking off batch processing with dynamic input from within a web application.

Many (most) of the collaborators in a spring batch configuration are stateful so they don't lend themselves to traditional singleton based spring context wiring. I originally tried defining these beans as prototypes but the problem was that one of the stateful collaborators needs to be injected TWICE into one of the components (as a collaborator and to register as a listener). It couldn't be defined as a prototype or two different objects would be injected and that wouldn't work.

In the documentation and on the forums, the Spring Batch team has suggested that you just use a new ApplicationContext for each run of your batch job. All of the examples that I've found construct the ENTIRE application context for each run of the batch job(s). That won't work in my case because my application context is being used by the entire web application. I can't refresh it (and the hundreds of beans it contains) just to breath new life into a handful of stateful spring batch beans.

Enter the ClassPathXmlApplicationContextJobFactory. This class allows you to construct your batch job beans from an existing parent ApplicationContext and a subcontext bean definition file. The key to this is that every time you request a job from the factory, it constructs a brand new sub context and wires up your batch job beans to the rest of it's singleton collaborators in your parent application context. Yippee!

The only gripe I had about this JobFactory implementation was that it expected the properties to be injected as constructor arguments (including the parent application context) and I wasn't aware of a way to pass the application context into a bean unless the bean implemented ApplicationContextAware. Hence, I created the following wrapper class that supports property injection making configuration a snap:

[sourcecode language='java']
public class ContextAwareJobFactory implements JobFactory, ApplicationContextAware, InitializingBean
{
private ClassPathXmlApplicationContextJobFactory delegate;

/* The parent application context */
private ApplicationContext applicationContext;
/* The job bean name */
private String beanName;
/* resource path to subcontext spring config */
private String subcontextPath;

public void setBeanName(String beanName)
{
this.beanName = beanName;
}

public void setSubcontextPath(String subcontextPath)
{
this.subcontextPath = subcontextPath;
}

/* (non-Javadoc)
* @see org.springframework.batch.core.configuration.JobFactory#createJob()
*/
@Override
public Job createJob()
{
return delegate.createJob();
}

/* (non-Javadoc)
* @see org.springframework.batch.core.configuration.JobFactory#getJobName()
*/
@Override
public String getJobName()
{
return delegate.getJobName();
}

/* (non-Javadoc)
* @see org.springframework.context.ApplicationContextAware#setApplicationContext(org.springframework.context.ApplicationContext)
*/
@Override
public void setApplicationContext(ApplicationContext context) throws BeansException
{
this.applicationContext = context;
}

/* (non-Javadoc)
* @see org.springframework.beans.factory.InitializingBean#afterPropertiesSet()
*/
@Override
public void afterPropertiesSet() throws Exception
{
delegate = new ClassPathXmlApplicationContextJobFactory(this.beanName, this.subcontextPath, this.applicationContext);
}
}
[/sourcecode]

Configuration is then very simple:
[sourcecode language="xml"]
