How to call a WCF service using web service task in SSIS ? WCF and SSIS 2005

subhash.veeravalli@gmail.com (subhash) — Thu, 06 Aug 2009 23:24:00 PDT

A day back I had a requirement where I had to write a simple web service which generates a Excel Report and had to get it executed as a daily job . So I thought of writing a SSIS package which will call a web service . But I am much into learning WCF ( Windows Communication Foundation ) these days .So I thought why dont I create a WCF service instead of Web service !! So I ended up creating a WCF service.

Now the question is Can I call a WCF service using Web service task in SSIS 2005 ?

The answer is Yes you can . All you have to do is follow the steps below .

Before we create a package , we need to make few changes to the Windows Communication foundation host and client so that we can make things work .

Make the following changes to the web.config of WCF host :

There will be a entry called as Bindings in the System.servicemodel tag in web.config of WCF host . You have to change the type of bindings in it as follows .

<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_ReportService"
closeTimeout="00:05:00"
openTimeout="00:05:00"
receiveTimeout="00:05:00"
sendTimeout="00:05:00"
maxBufferPoolSize="524288"
maxReceivedMessageSize="2147483647">
<readerQuotas
maxDepth="2147483647"
maxStringContentLength="2147483647"
maxArrayLength="2147483647"
maxBytesPerRead="2147483647"
maxNameTableCharCount="2147483647" />
<security mode="None" />
</binding>
</basicHttpBinding>
</bindings>

By default it will be wsHttpBindings in a WCF service . But in a web service it used to be basic Http Binding and web service task has been configured to work only with basic HTTP binding in SSIS 2005 . Since WCF service supports communication over different protocols , we can always set bindings and achieve the required functionality .

If your web service is also consumed by your web application or something , then you need to configure its web.config as below to enable it use the same binding (BasicHttp) which host exposes .

<bindings>
<basicHttpBinding >
<binding name="BasicHttpBinding_MPCService"
closeTimeout="00:01:00"
openTimeout="00:01:00"
receiveTimeout="00:10:00"
sendTimeout="00:01:00"
allowCookies="false"
bypassProxyOnLocal="false"
hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="2147483647"
maxReceivedMessageSize="2147483647"
messageEncoding="Text"
textEncoding="utf-8"
useDefaultWebProxy="true">
<readerQuotas
maxDepth="2147483647"
maxStringContentLength="2147483647"
maxArrayLength="2147483647"
maxBytesPerRead="2147483647"
maxNameTableCharCount="2147483647" />
<security mode="None">
<transport clientCredentialType="None" proxyCredentialType="None" realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>
</binding>
</basicHttpBinding>
</bindings>

If you observe the web.config entries , you can observe maxDepth ,maxContentstringLength and other attributes being set to 2147483647 . This has been set as my output of webservice (Excel file ) was very large . You can remove them if you want .

Now lets create a SSIS package using BIDS 2005 .

The first thing you have to do is setup your HTTP connection using New Connection Wizard .
Now save the WSDL of the service in a local path . You can get the WSDL by using the link you have used as server URL in the HTTP connection manager above . The link will be something like http://localhost/WCFservice/ReportService.svc?wsdl.Save it as [Filename].wsdl .
Now add a web service task from the toolbox of your Business Intelligence development studio ( BIDS ) .
Open the Properties of your webservice task and configure it as below.

Web Service Task Configuration :In the HTTP connection , select the HTTP connection you added above .
In the WSDL File field , give the local path to where you have stored your WSDL file .
Set OverwriteWSDLFile to true and click on download WSDL .
Now click on input in the left side pane .
In the input screen you can select your service and the corresponding Web methods .
Select the required one and go to output option .
In the output screen, you can set output type to either some variable or file connection as per your requirement .
Now click on OK and you are done with configuring your SSIS package to call a WCF service .

Now you execute your task and you can see it working . If you still have any problems feel free to contact me .

A-Squared Emergency USB Stick - Portable USB Malware Protection

noreply@blogger.com (A Silken Touch) — Sun, 28 Jun 2009 00:45:00 PDT

Cyber Security is a great warfare. There is always a race here between malware developers and security vendors. And by the very nature of the security software development process, malware developers are always ahead of the security software.

Present day malware have a characteristic that once they are able to enter your computer, they try to block you every mechanism, which can try to restrict their evil designs. They will try to disable your antivirus suites, they will change your browser homepages, they will try to modify your hosts file so that you are not able to access the security vendor websites and other forums, they will disable the update process of your security software and things like that.

There are fair chances that if your antivirus definitions are not updated, your antivirus installation will be crippled and handicapped beside the damage to your other applications.

In such a situation, you might need a security tool, which is ready to combat the malware, and is ready with the latest virus definitions.

A-Squared Emergency USB Stick is one such tool. It is a free tool, which from the reputed security software vendor EMSI. It is basically a combination of two security tools.

a-squared Free: With a-squared Free you have got the powerful a-squared Scanner including graphical user interface. Search the infected PC for Trojans, Spyware, Adware, Worms, Dialers, Keyloggers and other malign programs.
a-squared Command line Scanner: This scanner contains the same functionality as a-squared Free but without a graphical user interface. The commandline tool is made for professional users and can be used perfectly for batch jobs.

This tool is specially suited for the cases, when the GUI interface of your installed antivirus gets disabled and you cannot use it for any meaningful purpose. A command line tool is very useful in such a situation.

How to reset user session in IIS when using AJAX updatepanel extensively on the page ?

subhash.veeravalli@gmail.com (subhash) — Fri, 29 May 2009 21:20:00 PDT

I guess every ASP.net developer might be using Updatepanel control these days which lets us to do partial postbacks on the page .If you are using Updatepanel control once on your page , you wont come across any issues . But if you are using it extensively obviously you will run into many issues.

In a traditional ASP.net web application the users session timeout counter will be reset everytime a user requests a page from the server, thus by preventing the user’s session from getting timed out. However,In AJAX ASP.NET application which uses XMLHTTP request to update part of a page , the users session counter on IIS will not be reset . So How to prevent Timeout in AJAX Asp.net Application which uses updatepanels ? How can we reset user Session in IIS when so activity happens in updatepanel ? The solution is here . Read on .

Create a new WebForm - KeepAlive.aspx in your application.
Now go to the code behind of the webform by hitting F7.
In the page_load method of the webform (KeepAlive.aspx) add the following lines of code

Response.ContentType = "text/html";
Response.Write("Technade");

Now go to the page where you are using the updatepanel extensively and add the following javascript to the markup.

function sessionKeepAlive(sender, args) {
//Create a New web Request and make a call to KeepAlive
var SubRequest = new Sys.Net.WebRequest();
SubRequest.set_url("KeepAlive.aspx");
SubRequest.set_httpVerb("POST");
SubRequest.add_completed(sessionKeepAlive_Callback);
SubRequest.set_body();
SubRequest.get_headers()["Content-Length"] = 0;
SubRequest.invoke();
}

//This function processes the return values
function sessionKeepAlive_Callback(executor, eventArgs)
{
// If you want to check any returned value from server ,you can use this else skip it
//else leave as it is
}
//Raised after an asynchronous postback is finished and control has been returned to the
// browser.
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(sessionKeepAlive)

What we are doing above is that, whenever you make a asynchronous postback call to the server , we are requesting the KeepAlive.aspx from the server using a new web request which inturn will reset the user session in IIS.

This solution has been tested and it works. So you dont need to worry that your updatepanel activity is not resetting the session in IIS.I hope this one helps the developers.Please post your doubts and views as comments.This one also might help you

Banned by Adsense

subhash.veeravalli@gmail.com (subhash) — Sat, 23 May 2009 02:19:00 PDT

Yes ,I am banned by adsense . On the day I received a mail from adsense that they had banned my account , I was stunned as usual . As we all know adsense never let people know the exact reason behind banning a website. I finally entered some form requesting google to reinstate my account . But nothing happened.

So Why am I banned by Google adsense ?

The only reason I can think of is I am not updating my blog . Yes guys , if you have a high revenue generating blog/website and you are not updating it regularly , Google will consider it as Made For Adsense website (MFA) and they will ban the respective account .

Apart from this , there are lot of reasons why Google might ban your adsense account .

Please check here to find the reasons why Google ban your adsense account .

Beware of Microsoft Powerpoint Flaw

subhash.veeravalli@gmail.com (subhash) — Sun, 05 Apr 2009 07:30:00 PDT

Microsoft has warned that Hackers are targetting a unpatched flaw in Microsoft office Powerpoint to attack users PC 's .

Versions Vulnerable : Microsoft Office 2003 SP3,Office 2002 SP3 and 2000 SP3 .

Hackers will launch attack by making you open a powerpoint file which has been crafted already . When you open the file powerpoint will try to access a invalid object in the memory which in turn allows the hacker to execute code remotely on your system .

As per Security advisory , attacks are not spread yet heavily but they expect some limited number of expects targetted at some users .Right Now Microsoft did not come up with any patch for this flaw but they might do it in next patch.

So What should I do to protect myself against powerpoint vulnerability ?

Microsoft suggests us not to open files received from untrusted sources, use the Microsoft Office Isolated Conversion Environment (MOICE) to open untrusted files, and use Microsoft Office File Block policy to restrict the opening of Office 2003 and earlier documents.

Tata Nano Review - Shall I go for a Nano or Maruti 800 ?

subhash.veeravalli@gmail.com (subhash) — Mon, 30 Mar 2009 09:47:00 PDT

Hmmm this is a million dollar question to be answered .After reading lot of reviews and listening to people i personally built a opinion on this people 's car .So will I buy a nano or not ? What opinion do i have on Nano ?

When I start thinking about Nano ,the first ever question in my mind is Why TATA built this car ?? His Indica is doing good so as his Ace which are priced above 2 lakhs .When I heard his reply to this question , I am so happy that now Indian business echelons are thinking of customers.For your information Indian business people are never conscious of customer satisfaction. Indian customers never question about the quality of the product . Seeing a family travelling on a scooter with a kid standing in the front , a dad driving it and a mom holding a baby in her lap and if possible one more kid between the dad and mom,Mr Tata wanted to build something that will revolutionize these peoples lives.When I started thinking what he can build in a lakh , My thinking can not go beyond a Auto Rickshaw .But I was surprised when 6 feet Ratan came out of our little peppy toy called Nano in Auto Expo last year .

Did you ever hear of something called a operational efficiency ?? Nano is a perfect example of operational efficiency . You can read How Mr Ratan and his team achieved this here !! The Nano team of 500 people did a very brilliant job in building this little car . They achieved price efficiency mainly in material and by taking advantage of low cost Indian labour . They used plastic instead of metal but with no compromise in safety norms . As per TATA motors Nano will satisfy all the safety norms .

As a Indian , I am proud of what Mr Tata as achieved . They showed the world a brutal example of engineering . They proved the world that we the Indians are capable of achieving things rather than jut using things someone else has invented. So what things I consider can be reasons for buying the Nano ?

Pro s of Nano :
* Every one knows the Nano .Having it will be a kind of status symbol in earlier days . People ask you lot of questions about it .
* Cool design . A one lakh car is not expected to be so cool in design but the Indian automaker made it. Its peppy look does force me to buy it .It beats Maurti 800 in this point
* Brand TATA : TATA s products are known for their quality. Tata Vehicles are very low on maintenance so as Will be Nano .
* Price Tag : Not to be mentioned , yes I will certainly buy the Nano for its price tag . Its the lowest priced car in the world .
* Mileage : Nano will offer you more mileage that most of the other cars .Tata Motors say it will give you 20 + .

How is Nano in comparision with other cars ? Read on here .

Con s of Nano :

* In start may be the car might be a status symbol but with its numbers increasing and every one having it , you may not feel so elited of having it .
*A rear mounted engine with roaring sound reminds me of a sports car but its Nano man .This rear mounted engine surely reminds me of a diesel Auto :).
* Speed matters . Its top speed is claimed to be a bit above 100 but I dont think a 600 + cc engine can do it with 4 people on board .
* Its nearest competitor Maruti 800 is among the most reliable vehicles from the Indian car stable . It has been tested through times and its a tough vehicle. I personally own it and there is not doubt about it . It offers me a mileage of around 18 - 20 most of the times .Most of the people are still in a kind of dilemma whether Nano first version may have some glitches like Indica initial release .
* If you think of price tag , The basic nano which is of 1 lakh which will be given only to first one lakh customers and thats also on the basis of a electronic lottery . If I am buying a car for my family , I will surely look for something that has a air conditioner .For a Nano having a air conditioner , I have to pay around 1.7 lakh and I can get a Maruti 800 if I can afford 30 k more .
* Not to forget this , The most annoying thing is the application form and the deposit price. They charge 300 rs for a application and the deposit price is arround 70 k .Tata might had put this one to avoid huge bookings from customers but as a customer its not that much comfortable.
*Its dashboard looks to me much like a auto dashboard . I am not at all impressed with it dashboard did not give me a rich feel of a good car .
When I summarize all the pros and cons I dont see many strong reasons for buying the Nano .But yes , its a new kid on the block . If you like trying new things, you can book one .If you care about each penny you spend , you can save 30 k by going for a nano instead of a Maruti 800 .

Internet Explorer 8 Review - Why should I use IE 8 ?

subhash.veeravalli@gmail.com (subhash) — Thu, 19 Mar 2009 19:08:00 PDT

Microsoft shipped in its final version of Internet Explorer yesterday . IE 8 is considered a stiff response by Microsoft to its rivals . With the market share of Internet Explorer decreasing and number of rivals increasing day by day , Microsoft had to work on building something that will wow the users and turn them back to Internet Explorer .So what we have in the box with Internet Explorer 8 ?

AutoComplete Address bar : Just like the latest version of Firefox and chrome browser , now IE address bar is also not just for typing the URL .It provides autocomplete functionality which will get a list of results from your History and Favorites, organized by category based on what you type.The search will be done even in the content of the previously visited pages also .The address bar can also be used to display matching websites from RSS feeds as well. Choose Tools-->Internet Options-->Content, then click the Settings button next to AutoComplete. Check the box next to Feeds, and click OK and then OK again. Now when you use the Address Bar, information from RSS feeds will be displayed as well.

Group Tabbing : This is something which you might notice first when you use IE8 . IE8 has improved the way it handles tabbing . For people who love to use new tabs instead of new windows , IE8 makes your life more easier now with group tabbing . When you open a new tab from a existing page, the new tab opens directly to the right of the originating one, and both tabs are given the same color. That way, all related tabs are automatically grouped and color-coded.In firefox , you have to use colour tabs extension to achieve this.If you open one more tab from the existing page, it won't appear on immediate right of originating one like earlier . It will appear in the far right of the group with same color as of the group .You can even move a tab from one group to other by just dragging it . You can control a entire group just by right clicking on one tab and choosing the right option as shown in the figure.

Tab Handling : Each tab is isolated from the others, so if one tab crashes, the entire browser won't close down. You can restore the crashed tab, and when you do, it reloads with the information that it had when its crashed, such as a partially written e-mail or a video . If its a video ,it will start playing at the point the tab has crashed .IE8 even have a new feature to reopen the closed tabs. To reopen the last tab you've closed, you press Ctrl-Shift-T. To see a list of recently opened tabs and choose which to open, you right-click any tab, select Recently Closed Tabs, and pick the one you want to open .

Accelerators and Web Slices :This is the most noticeable feature in the latest version of Internet Explorer. Accelerators are nothing but addons which will get more information on the text you have on a webpage like searching , translation , send a email ,digging the link , getting the Map of a address .... It is a kinda mashup which shows you the result of accelerator in the current page itself . Rightnow we have most of the accelerators from the microsoft such as Live Maps, Live Search and Windows Live Spaces. There are others as well, including ones from Amazon, eBay, Facebook and Yahoo. Its not tough writing a accelarator . You can do it easily with knowledge of basic XML .

Web Slices offer one more way of easily getting information. They deliver information that is changing on a particular website which you are not visiting directly . For e.g if you have a website that displays latest news , you can get the news without visiting the website .When you visit a Web page that csupports slicing, the Web Slice icon on the right side of Favorites bar turns green as shown in the figure. when you click it you can see a list of Web Slices available on that page. If you select one it gets added to favourite bar. When its content changes, the title turns bold. Click the Web Slice, and it displays the content just like a live bookmark in firefox.You can click on the content to go to the web page .

Improved security and privacy : The latest concept introduced by Microsoft in IE8 is InPrivate Browsing . InPrivate Browsing destroys any traces of information about your surfing activity when your web browser is closed .It means that all the cookies, temporary Internet files, browsing history, form information, and user names and passwords all vanish.You can start InPrivate Browsing by opening a new tab and selecting Browse with InPrivate or selecting it from the Safety button on the top right corner of the browser window.
There is one more smart feature in IE 8 called InPrivate Filtering .Users are often not aware that some content, images, ads and analytics are being provided and shared across websites . InPrivate Filtering provides users an added level of control and choice about the information that third party websites can potentially use to track browsing activity.InPrivate Filtering is off by default and must be enabled on a per-session basis. To use this feature, select InPrivate Filtering from the Safety menu. To access and manage different filtering options for Internet Explorer 8, select InPrivate Filtering Settings from the Safety menu. To end your InPrivate Browsing session, simply close the browser window.
Microsoft has even added some other safety features to IE8. It blocks the most common type of cross-site scripting attacks, and offers better protection against malicious ActiveX controls. Microsoft also claims that IE8 protects against "clickjacking " , in which a hacker can place an invisible button underneath or on top of a legitimate button and fool you into activating malicious code or making private information public.

Compatibility with IE 7 websites : Sites that were built for IE 7 might now display prperly in IE 8 . To avoid compatibility issues, Microsoft designed IE 8 in such a way that the browser is set to automatically switch to Compatibility View. You'll be notified when it happens with a balloon tip which appears briefly on the tab, telling you that the browser is displaying in Compatibility View.

Conclusion : So what I finally say about Microsoft latest Internet Explorer ?I can say in one line : Switch to Internet Explorer 8 .

After using the browser , I did not see any big difference in speed compared to Firefox or IE7 but there is a difference in features . Most of the features are targetted at increasing the productivity of the users .I found it much better when working with AJAX applications which might be due to enhancements in forward and back navigation buttons .With a lot of features added , IE 8 is surely something to try on guys . Its fast , easy , safe and secure .

Now you can turn off Internet Explorer in Windows

subhash.veeravalli@gmail.com (subhash) — Fri, 06 Mar 2009 22:02:00 PST

Yes , you are reading it correctly . You can turn off Internet Explorer in your windows now . Microsoft now lets us turn off some windows key features. Continue for further details.
with Windows 7, users will have the option of disabling a number of features of the operating system . Microsoft has been facing lot of regulatory and anti trust issues in the recent times .Microsoft lost a long-running battle with EU antitrust regulators in 2007 over the way it bundled media player software into the Windows operating system.In the media player dispute, European union heavily fined Microsoft and forced it to sell a version of Windows without the offending program installed. To avoid such kind of issues , I think Microsoft has came up with this solution .

Windows Media Player
Windows Media Center
Windows DVD
Windows Search
Handwriting Recognition (through the Tablet PC Components option)
Windows Gadget Platform
Fax and Scan
XPS Viewer and Services (including the Virtual Print Driver)

With windows 7 Microsoft has stripped most of the programs from the Operating system Which are still available for download on Windows Live .

I dont like the way how people actually look at Microsoft . They developed things which are better than others and before any one does something , MS does it .Thats why they are here . They have better marketing strategies in place . But people always cry on Microsoft . They want a operating system for free . :) .If a OS comes out without anything , then are these people happy ?

What do you feel about Microsoft ? Lets others know through your comments .

TCS to layoff more people in the coming days

subhash.veeravalli@gmail.com (subhash) — Thu, 05 Mar 2009 18:31:00 PST

Sources has revealed that the TCS, India 's largest software giant is going to take few tough steps to sustain in the present environment . Since economists and experts don't see a economy recovery in the near time , most of the customers are feeling the pain of slowdown and are pressurising the outsourcers to maximise the efficiencies . To keep itself equipped against the global economic activity , the company has rolled out four measures which are going to be implemented with immediate effect .The four measures are as follows :

There will be no recruitment of experienced professionals unless the company feels its extremely required . People will be given cross skill training to manage the internal needs .
Since outsourcing means saving money by working from a low cost place , the company will concentrate more on offshore leverage . Non Critical positions on onsite will be moved to offshore .
There will be no promotions until the situation improves .
If you are in the underperforming section or in the under utilised section , the company might counsel you or might even ask you to leave .

Its not only TCS , all the companies are implementing different kind of measures to sustain in the present environment . It might not sound good to the employees , but if the companies has to sustain , they have to undertake this . The companies are trying to do everything so as to retain employees . As a employee of the organisation , its time for us to stand by them and help them sustain . Do remember that When your company does good , it will always do good to you .

How to remove " This page contains both secure and nonsecure items " ? ASP.NET https Menu workaround

subhash.veeravalli@gmail.com (subhash) — Wed, 04 Mar 2009 18:24:00 PST

Somedays back , I had to deploy a ASP.Net application in a secure environment for my client . But when I deployed my application in https environment , it started displaying a message " This page contains both secure and non-secure items. Do you want to continue ? " . Being a developer , this message is ok to me . But clients who are generic users might get scared of this . So I was asked to remove this error message . So How to remove " This page contains both secure and non secure items . " ?

This message basically occurs when your application try to access a resource like image or some other file from a non secure server . So first you have to search for http in your code . Find all http links and replace them with https .
Now check whether all your images and files are hosted on the same secure server where your application has been hosted . If not move them to secure environment .

These two are the common reasons why this error occurs . In ASP.NET if you are using Menu control , it will also this error . So what is workaround for Menu in https ? If you are using the master page , paste the following piece of code in your masterpage code-behind .

protected override void Render(HtmlTextWriter writer)
{
Page.ClientScript.RegisterStartupScript(typeof(Page), "MenuHttpsWorkaround", Menu1.ClientID + "_Data.iframeUrl='Blank.htm';", true);
base.Render(writer);

}

Add a new blank HTML page to your application folder and replace blank.htm in the above code with that page . Aslo replace Menu1 with your Menu Item Id . Once you make the changes , publish the code and check it in secure environment . The error message would not display again .

Life of a IT engineer in 2009

subhash.veeravalli@gmail.com (subhash) — Sat, 10 Jan 2009 20:04:00 PST

"-----------------------------" .Yes its a question that can not be answered . Every doubt you get about the life of a IT employee in 2009 is a question mark forever . IT is dependent on other sectors heavily for its existence . In the era of recession where all sectors are going down , IT has obviously got affected . Especially Indian IT which is dependent on the outsourcing by companies in developed nations is badly hit . As people start saving money instead of spending them in US and Europe , Companies in those nations get hit first . As their profits start decreasing , these companies look at decreasing their costs .

Yes outsourcing does help them in doing it ( reason why NASSCOM is still confident on Outsourcing ) , but they will try to pressurize the IT co's to make the outsourcing overefficient and to offer them at cheaper prices .This will continue to happen until clients of our IT co's get profits like earlier . People seem to be very confident that Situation will be back to normal by mid of 2010. But I dont think so . This time it will take long to get back to normal . Once people go in saving mode , making them think of spending again needs lot of efforts. This is what has been happening in India for generations . Since some generations Indians were in savings mode . They thought that they dont have enough money . But once they started getting money , they slowly went into spending mode and India is presently in spending mode . But now if people feel that they need to save money as cash flow is going to decrease, it will take generations to make them spend it .Thats why recovery of recession will not be a rapid process . Going into recession happens rapidly but not the recovery will do .

Now as clients to pressurize your company to reduce costs , your company will investigate its operational costs first . Till now IT companies have been spending lavishly on travelling . So , they will try to decrease travelling as much as possible. They will ask you to use other modes of communication like phones and VOIP services . They will reduce people oscillating between onsite and Offshore . They will reduce power usage and try to decrease other perks which they give you normally like snacks and food .AC's will be switched on only in official office timings (9 AM-6PM) . Number of working hours will be increased as companies can get billing for extra hours thus by increasing revenue . Human resource department will be asked to postpone promotions of people .Forget about hikes completely( Wish that you atleast get the salary you are promised of earlier :) ) . These operational costs are for increasing the margin internally in the company . To client also , they need to show that they are trying to decrease his costs .So they will say they will get the entire work done from offshore as much as possible . They will ask all teams to decrease the number of people working in onsite under the Name Offshore Leverage . Companies are looking for a offshore leverage of 90% all over these days . The companies will make employees dance to their tune saying we are doing all this to keep you r jobs safe.

IT employees have to be in a condition where they can not demand anything from the company , if they want to have their job safe . Stay happy with what your company offers. Companies have good advantage of the present situation . Attrition rate will decrease very much as people are not finding jobs easily in market like earlier .But as the situation starts improving attrition will touch high rates as all frustrated employees keep moving between companies . But IT guys companies have developed enough workforce by training large number of freshers to deal with attrition problems . So if you say I am going to leave the company , they will just say " yes Please " .

So IT guys , for the next one or two years, you can not do what you want . Just do what your company wants [:P] .Thanks to recession .

Ghajini review ( Aamir rocked )

subhash.veeravalli@gmail.com (subhash) — Sat, 10 Jan 2009 06:11:00 PST

Inspired by the hype given all over , Last weekend I went to see the latest flick of Aamir khan , Ghajini . I saw the original version of ghajini ( a Indian version of Momento ) in telugu and tamil before . Having a confidence on Aamir , I thought he will try to do something different in the new version . But what I felt when I saw the movie ? Keep on reading : ) ..

The movie has nothing except Aamir . Aamir has done every effort from his part to create a master piece , But it did not work this time . Let me say a few words to Aamir before I start writing about the movie .

Dear Aamir ,
You are fascinating actor .You have enough talent with you to stand as a superstar . Your dedication towards your job , your hardwork is always appreciable . I am confident that audience are not disappointing you much by watching your movies in pathetic theatres . But dude dont try to copy someone . Still now what ever movie I saw in which you played a role are just original versions and I always praised you for your work . You did extremely well when you did something yourself . You are good in creating things . But I think you are not good in analysing a role which is already done by someone else . You did somethings which are not in line with your fan thoughts . For knowing the mistakes you have done in the movie , you also have to read the rest of review .

Lets start with Aamir 's introduction part . The hero ( Surya) in the original version of Ghajini is of good height . So the director made him fight with bad guys whose height is in sync with him and he made them fall in one shot . It was good to see that . But Aamir is a short fellow . He is made to fight with guys who are quite taller than him . The fight is supposed to be like Aamir dominating them with his strength . But as the guy is longer , it looked like Aamir is struggling to fight with him. what I mean is if hero has to dominate the villains ( by making them fall in one or two shots ) , he should make sure that they are weaker than him in physique . Next comes the heroine . The introduction song of the heroine in Telugu version was very good . But in Hindi , its not upto the mark . The music would had been better for that song and even the picturisation too . The whole movie is a copy paste . The heroine part which played a great role in making the early versions hit , can not do this time . How can Aamir think of putting some south Indian heroine beside him in a bollywood movie ?

The first half is better compared to second in the movie . The second half is just filled with violence which follows a beautiful song Guzarish . I should say about Aamir this song . His body was shown as if he is some girl . I understand Aamir that you have developed this to show your competitors that you are better than them but the picturisation of movie can not add value to your body . You would had utilisted it better in the movie . The entire movie looks as if Aamir is acting in some south Indian movie . You would had gone for some bollywood director instead of Murugadoss who tried to show you just by replacing surya in the original version with out trying to adapt it to the tastes of bollywood . The heroine should also had been changed .

Oops , I should mention about the changed climax na . Some people said that the climax is highlight of this movie as it has been changed . But I did not find it so . There is just some logical act there and nothing much interesting apart from it .

In a whole , the movie deserves to be a one time watch that also only if you are a fan of Aamir .
It deserves a rating of 2.5 from me .

Reality children

subhash.veeravalli@gmail.com (subhash) — Sat, 27 Dec 2008 02:07:00 PST

I am watching a show in one of the regional channels these days where they are organising a competition of singing for children with title Sarigamapa - little champs . I saw both series of this show . Its good to see kids singing , but the way they are made to , It dont seem to be entertaining . I dont know whether the government will ever come up with a law whether there is a lower limit on children's age before they get introduced to this unreal dramatic reality shows .

Did you notice the little kid on the right in the above picture ? She might be hardly 5 years old . She can not even speak properly . She can not even understand comments given to her song by judges properly . She never sang so beautifully till now that she get a chance to sing in a finale . I agree she used to sing very cutely as she is still a kid but ...... The only reason by which she probably would had got forwarded till grand finale is becase she is a reason for the increase in ratings of this show . People used to see the show as it was good seeing the kid singing very cutely .They even promoted the show 2 or 3 times showing the judges giving her bad comments and the kid getting embarassed as a trailer .So weird .

Itwas atleast fine . Now they brought her to finale and again they made her cry . That is the promo for the finale . They showed the same trailer 100 times a day . In the finale they made her sing for two hours and in the end they sent her home crying . It was soo embarassing to watch that show .When the show ended , I decided never to watch that channel again . Better you also dont .

And dear parents , next time you send your kid to a show , dont think just your kid will get name and fame . Think of their feelings before you send them in . For the channels , its just a commercial event . Send and encourage your kids to participate only when you think they really fit in there easily .

How to remove a value from array in javascript ?

subhash.veeravalli@gmail.com (subhash) — Sat, 27 Dec 2008 01:39:00 PST

Yesterday I was writing javascript and I came across a problem where I had to remove a value from a array in javascript . As usual I tried Array.remove[index] . But it did not work . So how to remove a element from Javascript array ?

Its quite simple . There are two functions which serves your purpose .

splice :

Usage : If you know index of the element / elements to be removed ,
ArrayName.splice(index,Noofelementstoberemoved) ;

E.g : If you want to remove single element from second position in Array=['one','two','three','four','five'];
use Array.splice(1,1) . The result will be

['one','three','four','five']; .

Remove :
If you dont know the index of a particular element to be removed but you know the value of it ,
You can use remove .

Usage : Array.remove('Valuetoberemoved') ;

E.g . To remove fifth element in the above array , use Array.remove('five') ;

Nachavule review - A typical Ravi babu direction - Produced by Ramoji Film City

subhash.veeravalli@gmail.com (subhash) — Fri, 19 Dec 2008 21:18:00 PST

One line review : 50 -50 .. Its a ok kind of picture.

Pro : Comedy in first half of the movie .
Con : Extreme psentiment in second half .

Nachavule is a story of two teens who are just done with their matriculation and how they fell in love after that ( obviously with troubles ). Director ravi babu dealt with the feelings of a teen girl extremely well in the first half of the movie . He was almost nearer to reality in this context . But in the case of the guy , he just came with usual telugu movie stunt featuring a fellow who wont do any other thing in the day except roaming behind the girl and going nuts about her . The family of the guy is somewhat comical . A dad who never cares about his wife and who never knew how to express his love to kids , A mom who does everything to her husband thinking he will thank her someday for what shez doing and defending her kids whenever they do a mistake , A little brother who steal things in his home and sell them in shop . The converstations between the dad and the little brother of the hero are very funny . E.g In telugu paina means Top and kindha means Bottom . The father asks the kid to give names of fruits showing a page with figures of a pine apple on top and a apple in bottom . The kid replies , Paina apple (Top apple) and kindha apple (bottom apple ) [:)] . One more is like the father asks him , if you have six sweets and i ask you to give me two , how many will you have ? The kid replies "Six" . The father aks him how ? The kid replies Its because I wont give you my sweets haha .

The first half of the movie is dealt with the guy trying to find some girl friend as he never had one in his life . He eventually tries and suceeds in impressing Anu to become his friend ( who works in a coffee shop to help her diseased father ) . The hero saves Anu 's father life once and Anu promises him that she will return his favour in any way he asks her . The guy asks her to be his girl friend for 15 days and if she feels he is not good enough for her , she can leave . But Anu fell in love with the guy in the 15 days and she ends up kissing the guy which is recorded by the guy in his mobile . After this , the guy is able to find lot of girls and he forgets Anu . With this the the first half ends and the troublesome second half starts . One day heroes little brother steals his phone and sells it in a mobile shop . The mobile shop owner sees the MMS and circulates it all over as a result of which the girls life gets spoiled . Now the girl hates the guy . In the mean the guys mother fell ill and she dies . But she makes her husband and kids realise how to take care of each other after she dies and what a woman expects from a man . The guy realises this and he is back on business . Now the movie is about what troubles he will cross to get the girl .

Believe me , Second half is extremely psentimental and if the movie would had been a little bit longer , I would had walked out . But the first half is worth watching . Technically the movie is very good like other Ravi babu movies who display some effect of hollywood on his movies photography .

How to run windows applications in Linux ?

subhash.veeravalli@gmail.com (subhash) — Sat, 13 Dec 2008 19:29:00 PST

Linux is all time favourite OS for Open source lovers . The only problem people ever have with Linux is applications . They don't have all their favourite windows applications made for Linux . Although Linux has got alternatives for Windows applications , not all have been covered . You can find Open source alternatives for windows applications here . Just go to osalt and enter the name of windows application for which you want to find open source alternative and Osalt will display you the list . Don't want to settle yourself with alternatives ? How to run your favourite windows application in Linux ?

There is a application called WINE ( Wine Is Not an ( windows ) Emulator ) which is a freeware that aims at allowing us to run windows applications in POSIX or Unix like Operating systems .WINE implements the Windows API entirely in user-space, rather than as a kernel module at the time of writing. Services normally provided by the kernel in Windows are provided by a daemon known as wineserver. Wineserver implements basic Windows functionality, as well as providing extra functions such as X Window integration and translation of signals into native Windows exceptions. It just acts as a compatibility layer for running windows applications .

Download WINE HQ .

What not to do in Ubuntu ? Dangerous Commands for Ubuntu

Once you install WINE , follow the steps below .

Check whether WINE is installed or not by typing the command : locate wine . It should display a list of WINE related files .
Make sure you have mounted the windows drive .
Edit the file /etc/wine.conf by changing the line under ' Drive C ' to Path=/mnt/win .
Save the edited wine.conf file and copy the file user.dat to your Windows directory c:/windows/profiles/ .
Now type: cd "/mnt/win/Program Files/Accessories" then type: wine ./Notepad.exe .
This will run Notepad on your Linux OS. You can load other programs also by giving suitable directory paths .
If you are planning to run a game or other program that uses your midi , then Linux midi-sequencer needs to be installed .

Note that for running all kinds of programs you need to load sound and graphics properly related to that program which I can not explain briefly in this post .

How to copy text and files to your desktop from remote PC ? Share clipboard between computers !

subhash.veeravalli@gmail.com (subhash) — Mon, 08 Dec 2008 18:17:00 PST

Most of the IT engineer might be working on remote PC 's in their day to day life . One of the very common problems we face working in remote PC is that you can not copy and paste things from your remote environment to your local desktop ( You might be restricted or something else ) . In such a case , if you still want to copy something from remote environment to your desktop , How can you achieve it ? Technade gives you two ways to achieve the same .

Tweak windows : You need to do a simple tweak inorder to achieve this which is as follows . Go to your control panel by navigating Start->Control Panel->Administrative Tools->Services . Now you can see services listed over tere . In the list enable and start the following services in the order shown below:

Network DDE DSDM
Network DDE
ClipBook

Thats it , you can now copy and paste text / files / graphics from your remote desktop . If you want to check whether its working or not , Open your clipboard viewer by typing clipbrd in your run prompt and check .

Sometimes , you can not do this , if you do not have enough previliges to enable services in your computer .

Method 2 ( via internet ) : In that case you have one service called CL1P.net which acts as internet clipboard . Remember that you need to have internet connection on both the computers . All that you need to do in this website is Enter a URL that starts with http://cl1p.net in the text box given. Replace technade below with any word you want .
E.g : http://cl1p.net/technade/.

In the page that opens upload text ,graphics , files ( size upto 30 MB) by selecting the appropraite option in the left side menu which looks like as shown in the figure . Access the same URL from your other computer and get the text or files whatever you want .Good thing with this site is we need not have to fill signup form to do all this .

So simple na !! if you know any other way so that you can copy and paste files from remote PC , let others know by throwing your valuable comment .
