Debugging ColdFusion

ColdFusion provides detailed debugging information to help you resolve problems with your application. Debugging can be done in two ways:

1.By specifying the DEBUG attribute in tag.
2.By enabling server side debugging in ColdFusion Administrator panel.

For instance,

SELECT Distributor.Distributor_ID,
Distributor.Distributor_Name FROM Distributor ORDER BY Distributor.Distributor_ID Returns, q_GetDist (Records=9, Time=421ms) SQL= SELECT Distributor.Distributor_ID, Distributor.Distributor_Name FROM Distributor ORDER BY Distributor.Distributor_ID

Cellphone Hazards

Fact: Malignant brain tumors are the second leading cause of death in children and young adults in the United States, and this epidemic is largely caused by radiation from a cellphones which penetrate the heads of users. If you always use your cellphones for calls and has experienced ear pain, headaches, dizziness, insomnia, irritability, stress, memory loss, high blood pressure and ringing in the ears, you better start limiting yourself from using that mobile phone, or at least pave way to a number of safety options.Studies show that there is a correlation between cell phone emissions and a slightly higher incidence of human brain tumors, cell growth in human blood micronuclei, and DNA breakages. Other studies show that electromagnetic signals from cellular phones reduce the ability to concentrate, calculate and coordinate complicated activities such as driving a car. Using a cell phone is also responsible for impairing of memory and reaction times. Even the so called hands-free mobile speaker-phones do more as they emit 10-times more brainwave interference than handheld units. Sixty percent of the radiation emitted by a typical cell phone is absorbed by the user’s head, and the radiation that is coming out from the ear piece is four times out of the antenna, and a similar amount of radiation comes from the keypad and mouthpiece as well. It should be noted also that different brands and models of cellphones have widely different levels of emissions.

Four times the radiation is leaked into the side of the head than is actually being used to transmit a signal. Highest emission comes from the antenna region. The reason for the leakage is that manufacturers tend to lower down the production cost, in exchange of lessening down the radiation that would escape into the user’s head and lowering down possible risks, thus the source of leakage: poorly matched transmitters, feeds and antennas. It must also be blamed to the lack of shielding in the phone case.

It is important that mobile phone manufacturers should be alarmed with this scenario and start designing cell phones that will not endanger the health of users. Make sure that all cellphones are sold with head sets or earphones. In this way, the user will have the option of not using the cellphone close to his head. The truth is, the essential key to safety lies to the manufacturers themselves, by designing safety features that will help protect and reassure their customers.

Resolving the newfolder.exe virus

Two days back my PC got affected by this virus very badly as it eat up all my empty hard disk space of around 700 MB.

This virus is know popularly as regsvr.exe virus, or as new folder.exe virus and most people identify this one by seeing autorun.inf file on their pen drives. It is spreading mostly using pen drives as the medium.

So I will tell you that how to remove this virus manually.

I prefer manual process simply because it gives me option to learn new things in the process.

• Search for autorun.inf file. It is a read only file so you will have to change it to normal by right clicking the file , selecting the properties and un-check the read only option.
• Open the file in notepad and delete everything and save the file.
• Now change the file status back to read only mode so that the virus could not get access again.
• Click start->run and type msconfig and click ok
• Go to startup tab look for regsvr and uncheck the option click OK.
• Click on Exit without Restart.
• Now go to control panel -> scheduled tasks, and delete the At1 task.
• Click on start -> run and type gpedit.msc and click Ok.
• Go to users configuration->Administrative templates->system Find “prevent access to registry editing tools” and change the option to disable.
• Once you do this you have registry access back.
• Click on start->run and type regedit and click ok
• Go to edit->find and start the search for regsvr.exe,
• Delete all the occurrence of regsvr.exe; remember to take a backup before deleting.
• Don't delete the regsvr32.exe.
• Delete regsvr.exe occurrences only.
• At one or two places you will find it after explorer.exe in theses cases only delete the regsvr.exe part and not the whole part. E.g. Shell = “Explorer.exe regsvr.exe” the just delete the regsvr.exe and leave the explorer.exe
• Click on start->search->for files and folders. Their click all files and folders Type “*.exe” as filename to search for
• Click on ‘when was it modified ‘ option and select the specify date option Type from date as 10/16/2008 and also type To date as 10/16/2008
• Now hit search and wait for all the exe’s to show up.
• Once search is over select all the exe files and shift+delete the files, caution must be taken so that you don’t delete the legitimate exe file.
• Also find and delete regsvr.exe, svchost .exe

Now reboot your PC.

ROUND() function in sql

Syntax:
ROUND ( numeric_expression , length [ ,function ] )

numeric_expression Is an expression of the exact numeric or approximate numeric data type category, except for the bit data type.
length Is the precision to which numeric_expression is to be rounded. length must be an expression of type tinyint, smallint, or int. When length is a positive number, numeric_expression is rounded to the number of decimal positions specified by length. When length is a negative number, numeric_expression is rounded on the left side of the decimal point, as specified by length.
function Is the type of operation to perform. function must be tinyint, smallint, or int. When function is omitted or has a value of 0 (default), numeric_expression is rounded. When a value other than 0 is specified, numeric_expression is truncated.

SELECT ROUND(column_name,decimals) FROM table_name

Parameter Description column_name Required. The field to round. decimals Required. Specifies the number of decimals to be returned.

Want to make money with the iPhone SDK ?

There are success stories of people making close to $ 250,000 by writing apps for iPhone. Recently, Apple dropped an NDA that prevented developers from sharing their knowledge on the iPhone with others. A flood of tutorials and reviews on the iPhone SDK opened up.

Here is one tutorial on writing an iPhone app:

SQL: Joins

The SQL JOIN clause is used whenever we have to select data from 2 or more tables. To be able to use SQL JOIN clause to extract data from 2 (or more) tables, we need a relationship between certain columns in these tables.

Inner Join (simple join)Chances are, you've already written an SQL statement that uses an inner join. It is the most common type of join. Inner joins return all rows from multiple tables where the join condition is met.

Outer JoinAnother type of join is called an outer join. This type of join returns all rows from one table and only those rows from a secondary table where the joined fields are equal (join condition is met).

Undraggable alert

Yesday i was seeing an undraggable alert in flex ..its quite simple just set the property "isPopUp" to "flase" to not dgraggable and "true" for drggable.
Here is a code..you can try it


Script:
private function showAlert():void
{
title ="Undraggable Alert";
myAlert = Alert.show("HI Cognizant!!",title);
myAlert.isPopUp = false;
myAlert.status = Capabilities.version;
}

Difference Between URL and URI

The first difference, which is a hint for the different meaning,is what it stands for:
URI - Uniform Resource Identifier
URL - Uniform Resource Locator
A URI _identifies_ a resource by meta-information of any kind.
A URL _locates_ a resource on the net, which means if you havea URL and the appropriate protocol you can retrieve the resource.


There are many different URI, e.g.:-

URL - Uniform Resource Locator

URC - Uniform Resource Characteristics

URN - Uniform Resource Names
One characteristic of a URI is, that it gives information aboutexactly one resource. Another is there can be more than one URIdescribing the same resource.


That was the theory, here is an example:
URI: <http://www.w3.org/>

URI: <http://www.w3.org/>

URL: http://www.w3.org/pub/WWW/>
All lines describing the same resource (the URL describes the location).

Levels in (service) Quality!

No..I am not talking about CMMI Levels. Recently came across these in a book by Ron Kaufman
Level 1 - Criminal
Level 2 - Basic
Level 3 - Expected
Level 4 - Desired
Level 5 - Surprising
Level 6- Unbelievable!
(Think about it as how your client perceives the quality you deliver..the products you deliver..the services you deliver)

New iPod Touch faster than iPhone 3G

The second-generation iPod Touch uses a slightly faster processor than the iPhone 3G.
Apple appears to have upped the processing speed of the iPod Touch in order to help it go after the portable-game market.

Touch Arcade reports that the applications processor inside the second-generation iPod Touch unveiled in September is actually running faster than the processor inside the iPhone 3G, which runs at the same speed that the original iPhone and iPod Touch used. The new iPod Touch's ARM-based processor is running at 532MHz, while the iPhone 3G's processor runs at 412MHz.

A game developer interviewed by Touch Arcade noticed a huge difference in 3D-rendering speed as a result of the speed bump. As we remember fondly from our "megahertz madness" days of the Intel-AMD competition in the PC, processor speed is not the only measure of performance, but it is an important one.

With the arrival of the App Store, Apple has been marketing the latest iPod Touch as a gaming device in its latest round of commercials, almost completely ignoring the fact that it's a music and video player as well.

It seems that Apple has room to boost the clock speed of the processor to 620MHz, according to ARM's specifications, but that requires striking a balance between performance and battery life.

select keyword in rexxx

SELECT keyword in REXX is like switch case keyword used in c. This keyword allows to select one of the conditional expressions.

syntax :
select
when cond1 then …
when cond2 then …
otherwise …
end

example :
/*rexx*/
number = 100
select
when number < 5 then say "less than 5" /*condition not sastisfied.this statement will not get executed*/
when number < 50 then say "less than 50" /*condition not sastisfied.this statement will not get executed*/
otherwise say "it should be greater than 50" /*condition sastisfied.this statement will get executed*/

end

Pen Drive -a part of Life

Technology has always been a necessary evil.However, like many other equipments, pen drives are also a necessary evil and pose a potential security threat to the technology world. When placed in wrong hands, the portability and high storage capacity of the pen drive can be hazardous. The device has evolved as a threat to the corporate and other organizations where security of data is given utmost importance.
The threats that are associated with pen drives are serious. Some of them are listed below.

• Stealing of data


• Spreading virus


• Plant malicious software


• Causing data loss

Pen drives barely allow any security system in terms of password or any other built in security feature. So it is more likely that if a person loses a pen drive, the data inside it can be accessed by anyone. If it falls in wrong hands he or she can misuse it. a pen drive can be easily stolen or misplaced and the data stored inside it can be easily manipulated. There have large demand for pen drives with some security systems such as finger-print reader or protective software.


There has been a conscious protest against pen drives in many private and government organization. Though it is a convenient device for the productive brains, it has proved to be beneficial for the thieves as well. Pen drives are small in size and have greater capacity to store information. Hence the thieves can carry the device stealthily in pockets and take information.

Fetching a row from table(ispf) using rexx

This is a simple rexx code, to fetch a row from ispf table.
lets say the table name is "sample" & it has two columns "id" & "name"
id name
001 agent001
002 agent002
003 agent003

if u want to know the name of person with id = '001' . then this is a simple code.

/*REXX*/
TDSN = "aaa.dsn"
ID = '001'
ADDRESS ISPEXEC "CONTROL ERRORS RETURN"
ADDRESS ISPEXEC "LIBDEF ISPTLIB"
ADDRESS ISPEXEC "LIBDEF ISPTABL"
ADDRESS ISPEXEC "LIBDEF ISPTLIB DATASET ID ('"TDSN"') UNCOND"
ADDRESS ISPEXEC "LIBDEF ISPTABL DATASET ID ('"TDSN"') UNCOND"TNAME = "SAMPLE"
ADDRESS ISPEXEC "TBCLOSE "TNAME
ADDRESS ISPEXEC "TBOPEN "TNAME
ADDRESS ISPEXEC "TBTOP "TNAME
ADDRESS ISPEXEC "TBSCAN "TNAME" ARGLIST ( ID )"
ADDRESS ISPEXEC "TBGET " TNAME
VARNAME = NAME
ADDRESS ISPEXEC "TBCLOSE "TNAME
ADDRESS ISPEXEC "LIBDEF ISPTLIB"
ADDRESS ISPEXEC "LIBDEF ISPTABL" SAY VARNAME


result : agent001

JBoss is loosing its charm ?

Jboss is certainly facing an evolution competitive front, and basically has not reponded to it.
The competitive fronts are two-fold, and will be recognizable by even the most passing of observers in the middleware market.

1. Seam is losing month-by-month to Spring
2. Jboss is losing month-by-month to Glassfish

Here are some of the proof-points, first the JCP page for Web Beans, the standardization process of Seam:
http://jcp.org/en/jsr/detail?id=299

It shows a slower growth, while Spring rolls out S2AP and myriad other complementary technologies to seize the develper's attention. Seam is dying on the vine, and its own complexity does not bode well for a major roll-out of improvements any time soon

Just look at jboss.org, it is a mind -numbing array of ongoing and outstanding projects with SSO, ESB, and Rules among others seemingly having no delivery date in sight, that translates to project stability. This makes us to think whether JBoss products and projects is under-resourced?

AMD seeks redemption with ‘Shanghai’ chip

Let bygones be bygones. That's what Advanced Micro Devices is hoping for with the roll-out of its first 45-nanometer processor Thursday. The No. 2 PC processor supplier will make the case that Shanghai is not Barcelona. The latter chip–AMD's first quad-core processor–was rolled out in September 2007 to great fanfare but then faced prolonged delays. This gave Intel an opportunity to regain ground it had lost to AMD in the server chip market. Shanghai is not a new architecture but essentially a refresh of AMD's Barcelona Opteron chip. AMD claims Shanghai is 35 percent faster than Barcelona. The chip is being built on 45-nanometer process technology, while Barcelona was a 65-nanometer part. Typically, the smaller the geometries, the faster and more power efficient the processor

Excel - Tip -2

Excel enables us to restrict the values a user can enter in a cell. by restricting the values, we can ensure that our workbook entries are valid and also the calculations based on them are valid.
Follow these simple steps:
To create a validation list, we first need to type the values we want to include in the adjacent cells in a column or a row.
1. Click on the cell, in which we want to create a validation list.
2. Click on "Data" tab
3. Click on "Data Validation" option.
4. In the "Data Validation" dialog box, select "Settings" tab
5. Select the "List" option from the "Allow" drop down list.
6. Click in the "Source" field and Click & drag the validation entries (the one we have entered in the excel file)
7. Click on "Ok" button.
Now, the Excel will create the validation list, in the cell we have selected it.

Excel tip -1

Hide Rows by Grouping
Using the Grouping option present in the Excel, we can hide the set of rows / columns.
Follow these steps,
1. Select the rows / columns that we need to hide.
2. Click on "Data" tab
3. Click on "Group" option
4. In the Group dialog box, select Rows/Columns option.
5. Click on OK button
Now, the Excel will create a clickable button on the far left or top of the worksheet. The button displayed either minus or a plus sign, depending on what is displayed in the worksheet

A wonderful tool in Excel!

Having used Microsoft Excel for presenting reports in the client's side, I wanted to share how wonderful a tool this is. Arguably, it is a tool used at some level by most people in an IT organization. Be it creating simple reports, business presentations using its versatile charts or even creating some simple birthday party accounts, Excel is a very important tool in MS Office suite of applications.
While Excel's worksheet formulas are being used extensively, its VBA properties, if harnessed properly, are much more rewarding. Hence, a little bit about learning VBA for somebody who will be interested -
For a set of tasks to be performed, select Tools –> Macros –> Record Macro (Office 2003) or Developer –> Record Macro (Office 2007) and then start doing what you want to do. Stop the recording and then open the Macro editor (Alt + F11). You will find the code recorded for the steps you had went through. This will be a very good starting place to explore and leverage this wonderful tool. Using the VBA help next will help fine tune the skill…

Make a Step to SWITCH OFF…

Nowadays, we face lot of power cuts. We are worried about power cuts. All the weekdays we keep our self cool in Office. As soon as we reach home, our hands are in search of our Fan/Ac Switch…
The Next minute the power is off, we get irritated. We curse the EB Dept, Govt. and many others…. Do we ever care for switching off electrical items, after the use.
Have you ever noticed the street Lamps Glowing after 6.00 Am?
If yes, have you made an attempt to switch it off? Or
At least to make a complaint on this, to the Municipality?
Our duty not only ends in casting a vote to a person.
Whenever there is a problem. At the Max we do is getting frustrated, curse the people and walk off.
It’s every individual’s duty to take the responsibility for things happening around him/her.I don’t say that we should jump in streets and fight for the power cuts?


At Least make a step to put the Switches off…

Insertion Sort Implementation

Insertion sort is a simple sorting algorithm, a comparison sort in which the sorted array (or list) is built one entry at a time. It is much less efficient on large lists than the more advanced algorithms such as quicksort, heapsort, or merge sort, but it has various advantages:

• Simple to implement
• Efficient on (quite) small data sets
• Efficient on data sets which are already substantially sorted
• More efficient in practice than most other simple O(n2) algorithms such as selection sort or bubble sort: the average time is n2/4 and it is linear in the best case
• Stable (does not change the relative order of elements with equal keys)
• In-place (only requires a constant amount O(1) of extra memory space)
• It is an online algorithm, in that it can sort a list as it receives it.
  

In abstract terms, each iteration of an insertion sort removes an element from the input data, inserting it at the correct position in the already sorted list, until no elements are left in the input. The choice of which element to remove from the input is arbitrary and can be made using almost any choice algorithm.

The following method shows how to implement insertion sort with Java:

public static void insertionSort( Comparable [ ] a )

{

for( int p = 1; p <>

{

Comparable tmp = a[ p ];

int j = p;

for( ; j > 0 && tmp.compareTo( a[ j - 1 ] ) <>

a[ j ] = a[ j - 1 ];

a[ j ] = tmp;

}

}

How to Handle Apostophes in DB2

Let us say if we have a table named EMPLOYEE having 2 coloumns EMPLY_ID, EMPLY__NM . if we want to update the name of EMPLLOYEE (ID:142082) from Satish to S'atish then we can use the below query.
UPDATE EMPLOYEE SET EMPLY_NM = 's''atish' where EMPLY_ID =142082.
Just use the double quotes instead of single quote to avoid SQL error 'Unbalanced Apsotrphes'
The MF database will recognize the double quote as 'Apostophe'.


Where it will be useful:
when you are passing a input parametre value having apostophe to stored procedure or COBOL program,to update it into database.

Environment Variables in Java

Some Environment Variables to be set while using Java Applications:


JAVA_HOME Should point to the folder above bin (eg.. C:\java )
If using ANT
ANT_HOME C:\java\apache-ant-1.7.0
If using Tomcat
CATALINA_HOME c:\tomcat6.0\tomcat
If using JIKES
JIKES_HOME c:\java\jikes-1.22

Java on Ubuntu

Ubuntu has GCJ installed by default. A different version of Java can be installed using the Synaptic Package Manager. Sun's Java 1.5 and 1.6 are available through the package manager.

The problem is, even after installing Sun's Java, GCJ is the default.
The default version of java can be changed using the update-java-alternatives command.
update-java-alternatives -l will give the list of all installed java packages.

example output:
java-1.5.0-sun 53 /usr/lib/jvm/java-1.5.0-sun
java-gcj 1042 /usr/lib/jvm/java-gcj

update-java-alternatives -s java-1.5.0-sun will set Sun's java as the default.
For some applications like Ant, Tomcat to run, you nee to set the JAVA_HOME environment variable like below
export JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun

The above export can be put in /etc/bash.bashrc (for all users) or /home//.bashrc (for a particular user) so that JAVA_HOME is available on logon.

To remove shortcut icon arrows.

If you want to remove shortcut icon arrows. Then go to the Registry and do the follwoing activity.

Go to {HKEY_CLASSES_ROOT\LNKFILE], and delete IsShortcut.
Go to [HKEY_CLASSES_ROOT\PIFFILE], and delete IsShortcut.

/**
* @param args
*/
public static void main(String[] args) {
System.out.println("The Memory Allocation to JVM ");
long totalMemory = ((Runtime.getRuntime().totalMemory()/1024)/1024);
long freeMemory = ((Runtime.getRuntime().freeMemory()/1024)/1024);
long maxMemory = ((Runtime.getRuntime().maxMemory()/1024)/1024);
System.out.println("Total Memory::"+totalMemory+"MB");
System.out.println("Free Memory::"+freeMemory+"MB");
System.out.println("Max Memory::"+maxMemory+"MB");
}

How to hide a file in image

How to hide a file in image -
1. Gather the file you wish to bind, and the image file, and place them in a folder. I will be using C:\New Folder-The image will hereby be referred to in all examples as fluffy.jpg-The file will hereby be referred to in all examples as New Text Document.txt
2. Add the file/files you will be injecting into the image into a WinRar .rar or .zip. From here on this will be referred to as (secret.rar)
3. Open command prompt by going to Start > Run > cmd
4. In Command Prompt, navigate to the folder where your two files are by typingcd location [ex: cd C:\New Folder]
5. Type [copy /b fluffy.jpg + secret.rar fluffy.jpg] (remove the brackets)
Congrats, as far as anyone viewing is concerned, this file looks like a JPEG, acts like a JPEG, and is a JPEG, yet it now contains your file.
In order to view/extract your file, there are two options that you can take
a) Change the file extension from fluffy.jpg to fluffy.rar, then open and your file is there.
b) Leave the file extension as is, right click, open with WinRar and your file is there

Speed Up Shutdown Time for WinXP

XP clear your paging file (pagefile.sys) of its contents whenever you shut down for security reasons. Your paging file is used to store temporary files and data, sensitive information, such as unencrypted passwords etc.
So if extreme security isn't required, then shut down XP without clearing your paging file by :-
1. Run the Registry Editor ( type regedit in Run and enter)
2. Go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
3. Change the value of ClearPageFileAtShutdown to 0.
4.Close the Registry and restart your computer.
Now on while turning off XP , the paging file won't be cleared, and shut down will be more quickly.

Difference between JDK and JRE

The "JDK" is the Java Development Kit. I.e., the JDK is bundle of software that you can use to develop Java based software. The "JRE" is the Java Runtime Environment. I.e., the JRE is an implementation of the Java Virtual Machine which actually executes Java programs.

Typically, each JDK contains one (or more) JRE's along with the various development tools like the Java source compilers, bundling and deployment tools, debuggers, development libraries, etc.

Web Site Certificates

Can you please go over what Web site certificates are?
First of all, if a certain company or organization wants their Web site to use encryption and be secure, they must obtain a site (or host) certificate. If they don't, they will not be registered as a secure Web site. So, how do you tell if a site is secure or not? Well, we've gone over this before, but let's cover it one more time, just to be sure we're all on the same page. There are two things you can check on to find out if a site is secure or not. The first is a little yellow padlock in the bottom right corner of your Web browser. The padlock should be closed (locked) as well. The second is how the Web site's URL reads. On a secure site, the very beginning part will always be "https," rather than just "http." That extra "s" makes all the difference when it comes to security.
So, if you're visiting a site and you see either of those things, the site will have a certificate. You can view the certificate by double clicking the yellow padlock. Once you do that, a certificate dialogue box will pop up and you can read all about it. It will tell you the purpose of the certificate, who it's issued to, who it was issued by and when it expires. (If the site you're on just uses the "https" method, just double click in the area where the padlock usually sits. Doing that will bring up the same certificate box for you). For example, when you purchase something from online software store, the checkout page is secure. If you double click the padlock on that page, you will be able to see our certificate.
Another way you can view a site's certificate is through your browser's menu options. In Internet Explorer, go to File, Properties and then click on the Certificates button. The same dialogue box will then come up for you. In Firefox, go to Tools, Page Info and then click on the Security tab. You can then click on the View button to see that site's certificate. That may be an easier way for you to access the certificate information.

Regular expression

A regular expression is a pattern describing a certain amount of text or a regular expression is a set of characters that specify a pattern. Regular expressions are used, when you want to search for specify lines of text containing a particular pattern. A regular expression matches specific word or string of characters. You can search for words of a certain size. You can search for a word with four or more vowels that end with an "s."

There are three important parts to a regular expression. Anchors are used to specify the position of the pattern in relation to a line of text (like ^ indicates the character(after ^) should be at the beginning of string and $ indicates character(before $) should be at the end of string ). Character Sets match one or more characters in a single position like [a-z] means any single alphabet(lower case) and [0-9] any digit between 0 to 9 .

Modifiers specify how many times the previous character set is repeated like * represents zero or more times and ? means one or more times.

For example:^AD*B$ matches a string that starts with ‘A’ and ends with ‘B’ and should contain zero or more ‘D’s like AB, ADB, ADDB, ADDDB…..

Regular expressions are case sensitive.

There are some operators like:
\w - Matches a word character
\W - Matches a non word character
\s - Matches a space, a new line character or a tab
\d - Matches a digit character

Motherboard Cleaning Tips

Motherboard is the main part of your computer that contains all hardware components. Your computer motherboard could fry, if you do not keep it clean on periodically basis. Dust is the main cause to heat up your system and heat link to hardware failure. You can save your computer maintenance cost if you clean your computer on the regular basis. This will improve the cooling and performance of the motherboard components.

• To clean your motherboard first unplugs your system power from the electrical outlet.
• Using the screwdriver remove the side covers of your computer case and put them to one side.
• Check all data and power cables connections. Inspect all motherboard PCI and AGP slots.
• Remove all add-on card of your motherboard for example RAM, modem, VGA, sound card and LAN card.
• Now blow the air around all the motherboard sides and keeping away your blower nozzle 4 to 5 inches away from main board components. You can use vacuum cleaner also for this purpose but compressed air is the better solution to clean a system.
• At the end assemble back all cards, cables and side covers of your system.
• I recommend you doing this after every three months if you want to save your system life.

Lotus Notes Mails - Optimizing Screenshots

If you send a lot of screen shots through your Lotus Notes email, then this tip should work well for you.

First thing first: it is always more effective to use the the File->Import option or the Create->Picture option from the menu to insert an image into an email instead of just pasting in a screen shot. This is chiefly because the Windows clipboard stores the copied image in an intermediary format that Lotus Notes does not like much, and the translation is often disastrous. For GIFs and JPEGs, the Import or Create options work like a charm. The downside, of course, is that you have to take the pain of actually saving your screen shot to disk.

When you are pasting screen shots in directly, they sometimes grab more space than what seems appropriate. This can be remedied by adding a simple parameter to your notes.ini file (which is setup when Lotus Notes is installed, and houses user preferences, admin information etc). The name of this parameter is OptimizeImagePasteSize, and the entry that needs to be to the notes.ini file is OptimizeImagePasteSize=1 .

To edit the Notes INI file, you have to shutdown Lotus Notes. The INI file would be in the Lotus Notes data directory, which usually is the C:\Lotus\Notes folder. The notes.ini file can be edited in Notepad. A very strong note of caution: please do not mess around with the other parameters in the INI file; you do so at your own peril, and at the risk of incurring the wrath of site support!

The parameter itself works by reducing the size of the images that are pasted in. To be specific, it converts the image to 256-color, and also compresses it into a GIF format. Its not exactly a high-quality image, but it is fairly decent. Whenever you want high-quality, you can always import it in, as described earlier.

Once this parameter is included in the INI file, you will definitely notice faster emails when you send screen shots the next time.

Phone Etiquette

Today, one of my colleague posed me an interesting question : "It is common for you guys not to tell your name when you call someone?" My answer was may be yes, may be no depends case by case. Ha ha, funny answer, right!. Cool, anyway I observed that phone etiquette is very important when working in multi-cultural environment. So I reviewed myself and took a deep look at this soft skill which can win things for you. Just to share with you all here I put them together :

1. Try to answer the phone by second ring.

2. Say your name loud and clear.

3. Greet them in simple and friendly.

4. Speak slowly and clear.

5. Ask for their name(if they say) and contacts if needed.

6. Be clear of what you are saying.

7. Lower your voice if you normally speak loud. ( Keep mouth piece at least 2 inches away from your mouth)

8. Seek permission if you want to put the caller on hold.

9. If you want to transfer the call, inform the caller about whom you are going to transfer and transfer to him directly.

10. If caller wants to leave a message please take : Callers name and details ( Company name), timestamp, subject of the call, need a return call, contact details.

11. End the call with "Nice speaking to you" or "Have a nice day".



Things to remember :

1. Instead of 'I don't know' say 'That's a good question, let me find out for you'

2.Instead of 'I/we can do that' say 'Here's what we can do.'

3. Instead of 'Just a second', tell them how long will it take to complete whatever your are doing and tell them what it is about.

4. Avoid 'No', people hate to hears NOs.

5. When someone is blasting or emotional, you keep your nerve, don't over react to their trigger words.

6. If it is SUPPORT call, listen keen to the caller and with all senses. Take a note of details like Job name that failed, person who raised the ticket, person who is waiting for our update, etc.

7. Stop blaming the callers, its always counter productive to blame others.

8. Improve your tolerance levels.



With the above guidelines, one can improve quality of work as well as time taken to solve tickets(On-Call support cases) and will good relation with customers (callers). Atleast half of them, I do practise but need to improve. Thanks for the one who questioned me and gave me an oppurtunity to review this important soft skill. Hope it is/will be helpful to you too.

India develops a mobile for low price.

India built the world's cheapest car - the £1,250 Tata Nano - and has now unveiled the telecoms equivalent: the £10 “people's phone”.

The mobile handset, developed by Spice, the Indian telecoms group, is angled at the lowest end of the market. It has jettisoned all non-essential features, such as a screen. “It is just a phone,” Bhupendra Kumar Modi, the Spice chairman, who hopes to sell about 10 million in the next year, said.

Mobile phones priced under £20 account for a fifth of the global market. However, with half the world's population yet to make a phone call and Western markets becoming saturated, companies see huge potential in budget devices aimed at the developing world.

Linux vs Windows - Security

The reason i am writing this post is not becoz i am an expert in linux, but a newbie. As a newbie i think i know the difficuties involved in understanding new concepts and that helps me explain them better.

Linux is always known to be safe from viruses. I installed Ubuntu 7.0 in PC at home and was surprised to find that there was not even a single option related to the Root account.

To explain things better let me start with what a root account is, for the sake of readers who are new to linux. A root account is similar to the administrator account that Windows offers. An admin account gives you complete rights over the system - read,write,execute,install and even crash the system. I soon found out that this was one of the big reasons why Windows has 60,000 odd known viruses while Linux has less than 40. How?? Read on.

If you have installed Windows OS before you would be aware that, the set up provides you with an admin account right at the time of installation itself. Most viruses are transmitted as e-mail attachments. When the unsuspecting users get a mail like "Click here for cool WallPaper downloads", they click it and BANG!!! - in comes the virus. Why does this happen? Becoz you are the admin. The system doesnt interfere with whatever you want to do with it.

SO how does Linux avoid this mishap? Well, the very first thing you ll do when you install Linux is get yourself registered in a Linux forum(Really!! You cannot avoid that). And the very first advice that you will get from any Linux geek is that to think zillion times before you use the Root account(the admin). So, most of us will listen to that and well that is a huge prevention for viruses. When you try to run any executables from a non-admin account the system doesnt let you do that. So every time what you have to do is to log in as root and then click on the attachments and let the virus in. And since most users are known to be reluctant(or lazy) to switch and then come back to have a look at a silly attachment, safety is ensured.

But wait.. There is more to it. What if we dont listen to those geeks and use the root for everything? Then isnt that similar to running windows on a admin account? Yes!! But the latest versions of Linux have come out with an OS that does not have a root. Again the question comes up - So, what if i really want to run an exe that i know is safe? Wont the system
stop me everytime. For this they have a keyword in Linux called "sudo". I think it means - do things like a super user. So if you really want to run that exe, you need to use the sudo command. Now thats double protection. So if you want to run an exe you have to do some work to get it up and running.

Putting it all together - In windows, viruses have an easy way of making it in. But to bring a virus to a Linux box you have to work on it.

Dropdown Menus implementation using javascript

HierMenus (Dropdown Menus) - a common element in many websites/ web applications. Whether you are adding items to cart or looking for some news or listening to music, HierMenus will provide you navigation to reach the page you wanted with much ease and efficiency. As HierMenus will not be displayed until you want (on mouse over of a particular content) the web page will look clean and uncluttered.

One common way of building the HierMenus is by using JavaScript. The common drawbacks/hindrances faced while using JavaScript for building HierMenus are cross browser compatibility, efficiency, reusability and expandability. All the issues are tackled by separating the content for menus, style and functionality for display into reusable components.

• A CSS file for look and feel of HierMenus.
• A Js file (Loader,js) for creating HierMenus on load of page and Displaying corresponding HierMenus on mouse over of tabs.
• Another JavaScript file containing the data for the Menus in the form of arrays. The arrays will have width of tab, color for the tab, background color of tab, images links for tabs, a field for checking whether the corresponding link is having submenus are not like that, menu name for the link and Href value for the links.

On load of web page a function in the Loader.js file will be called and will construct all the HierMenus based on the no. of 1st level tabs (1st level tabs will be created in JSP/HTML page). On mouse over of particular tab, POPUP(‘tabMenuName’) function in the Loader.js file will be called and will display the corresponding 2nd level menus and on the mouse out of tab POPDOWN(‘tabMenuName’) function in the Loader.js file will be called and will make display none for that particular tab. POPUP(‘tabMenuName’) will also make sure that the Heir menus displayed will be visible to user(Horizontal and Vertical alignment of menus) for all window sizes.

Advantages by using this approach:

• Fast and efficient.
• Content, style and functionality are separated and made independent.
• Font color or style and background color can be changed with simple changes in the CSS file with out affecting the functionality.
• The number of menu tabs can be increased without affecting the functionality or look and feel.
• Dynamic display according to the window size and menu size.
• Cross Browser compatibility.
• Heir menus built using this are supported in IE6, IE7, Firefox2 and opera.

Our Official Email Abbreviations

In our official mails, nowadays we have a habit of using the abbreviations like FYI, FYIP, PFA or EOD in body of mail and NNTO or EOM in a subject line etc. Most of us when sending such mails assume that the person reading it is aware of these abbreviations. It need not be the case.

One of the person near my desk in office asked me “I am getting a lot of mails from the others with PFA in the top of the mail. Do you know what that means?” I told him it means “Please Find Attached”.

The idea of communication is to make the other person understand what you are thinking/saying and if that very purpose is not meet then why use it. Something that is common/known to you might not be known to the others, so there can be abbreviations which only a certain set of people are aware of. Even worse it can mean something very different in another country or culture. But if you have the habit of using it often then it is better to expand it in the first mail to a new person and then use the abbreviation in the subsequent mails. A much better suggestion is to refrain from using uncommon abbreviations in business emails.

P.S: FYI - For Your Information, FYIP - For Your Information Please.

This reminds me of another incident at the client place, other than India. I referred to the number 100,000 as 1 Lakh while speaking to them. The client did not understand it and I repeating it did not serve any purpose. Then finally I had to say it as one hundred thousand. Until then, I did not realize that the term lakh is predominantly used only in Asian countries like Bangladesh, India, Nepal, Sri Lanka, Myanmar and Pakistan.

Even i faced same kind of experience with one of the mail with no body(message) but subject as:
Please send your details soon <>

By the time i received this mail, i was aware of the only term EOD (End Of Day). Can u expect what assumption i have made for the term <> in subject line to be ?- as End of Month ... instead of End of Mail. lol

And about other abbreviations:
NNTO - No Need To Open
NNTOM - No Need To Open Mail
these are place in subject line only.

Delay Sending Email

I accidentally forwarded an email message to the wrong person in Gmail yesterday. I noticed just after clicking send … but a millisecond too late to fix it. A great feature for Gmail would be to have a delay the user could set on every sent message in their Outbox - say 1 minute to 5 minutes, that would allow users time to stop outbound messages.

Currently if you are using Outlook then this is possible. Microsoft Outlook (not Outlook Express) will allow you to set up a “Rule” to delay messages for whatever time period you need. This will give you a chance to open it and change messages before they are sent.

* Open Outlook, click on START, All Programs, Microsoft Office, Outlook.
* Click on TOOLS, Rules & Alerts.
* Click on New Rule “Start from a blank rule”.
* Click in Step 1 box, “Check message after sending”.
* Next, click on “On this machine only”.
* Next, Click in Step 1 box, “Defer delivery by a number of minutes”.
* Click in Step 2 box, “a number of” enter the number of minutes.
* Click on OK, click on Finish.

If you have set the Defer delivery by 1 minute and when you click on Send, your message will be held for one minute before being sent. If you realize there is something that needed to be changed, you just click on the Outbox, then click on the message to open, make any changes and click on send again. You will have another one minute, before the message will be sent. This procedure may save you some embarrassing moments.
