Is Partitioning a hard disk into multiple drives bad?
2008-08-27 13:59:00
Hard disk partitioning is almost a must, according to what I have heard so far from my colleagues and other professionals (may be same for you). I am used to partition a hard disk at least to three drives; "C" for OS (Operating System), "D" for programs and "E for other files like documents, archives. But I got a chance to read some material on hard drive performance and it completely argued my partitioning practices.When considering the speed in reading a file from hard drive following are two important points related to partitioning.1. Files in outer tracks are readable much fasterIt is a well known theory in hard disk read/writes that performance is much higher in outer tracks compared to inner tracks.2. When partitioning a hard disk, the first partition is created in the outer tracksIn creating partitions, the first partition is created in the outer most tracks while each new partition is created in inner tracks than the previous. So the partitions in a hard disk would look as t...

Cellspacing vs cellpadding - Table attributes comparison
2008-08-21 14:43:00
In HTML Table s (<table>) there are two attributes named, cellpadding and cellspacing. What is the different between cellpadding and cellspacing? Both these are capable of creating some empty space inside a table.cellspacing : space between cellscellpadding : space between the cell border and it's contentLook at the diagram to clarify this further. As the word "cellspacing" suggests, it denotes the spacing between cells; it is something easy to remember. "cellpadding" keyword can be considered in relation to the "padding" attribute in HTML/CSS; padding is used to denote the space between the content and border of box type elements. Following is a simple code example to demonstrate the difference.<table cellspacing="15px" cellpadding="20px" bgcolor="#00EE00" width="300px"> <tr> <td bgcolor="#339966"> <div style="background:#FFFFFF;"> Cell 1 ...

If Michael Phelps is a country himself alone
2008-08-18 14:07:00
What if Michael Phelps is a country himself alone rather than representing United States of America? Michael Phelps has already gathered 8 Gold medals in Beijing Olympics 2008 including 3 relays. Most of the participating countries happened to go back empty hand, so many players are participating knowing they are not up to the level of winning a medal. But consider this man, he's breaking world records in most appearances. If he is playing himself alone as a separate country named "Phelps" he would still have 5 Gold medals and ranked as 11th country in Beijing Olympic medal table. Around 200 countries will be behind him. Medal table would look as follows.RankCountry Gold1China352USA14 (19-Phelps)3Australia11.....11Phelps5He is creating new history with a set of world records and we are really proud to see such a person in this planet. We doubt any one living right now in this planet will be able to witness another performance like this in their lifetime. If they could, it will be a...

[Cricket] Most wickets in debut Test series - World record by Ajantha Mendi
2008-08-11 05:13:00
Most wickets by a player in his debut 3-match Test series; a 60+ years old world record has been broken. By whom? By Sri Lankan newly found precious mystery spinner Ajantha Mendis. He produced this new world record yesterday, 2008-08-10 with the wicket of Sachin Tendulkar, another master of cricket. Up to now, he has got 25 wickets in this series, and he has passed the 24 wickets record held by English bawler named Alec Bedser. Ajantha Mendis has so many variations, and so difficult to read from the hand. Most of the Indian batsmen are still struggling to play against him while he is improving with his variations and accuracy.In the current India-Sri Lanka Test series he played in all 3 matches (and 6 innings) and performed fabulously. Still he is bawling in the 2nd inning of the last Test match and 5 more wickets are left in Indian team. So we wish Mendis to get some more wickets out of those and improve his record into an untouchable one in history.Well done Menda.Update:Ajantha a...

Verify calling Javascript function available to avoid runtime errors
2008-08-07 13:55:00
Do you want to verify whether a Javascript function exists before calling it to avoid runtime errors? With Javascript we used to call Javascript functions. But sometimes our Javascript code tend to throw runtime errors and showing then on the browser. For this there can be several reasons including; incorrect function names or invalid .js file names causing some functions not loaded into your web page. Javascript has the ability to check this. For that we can use the typeof keyword, and check whether that is of 'function' type or not.Generally we will be calling a Javascript function without checking whether it exists. Following code shows how we would call a function.function callClient(){ myTestFunction();}If the function named myTestFunction() is not available, the browser will show an error message at runtime. But we can check whether this method is available even before calling it, avoiding the errors. Following code snippet checks the existence before calling a function.f...

Write Java with JDK 1.5 features and run on JRE 1.4
2008-08-06 14:33:00
Have you being writing your Java code on Java 1.5 (JDK 1.5) with new features like auto boxing, generics and enums? And suddenly realized that your customer's servers are still using Java 1.4 (JRE 1.4)? This is not a surprise since most of the customers are not in a position to take a risk and try the newer versions as they are running live/online businesses. But as professionals in the software development field, we have to move with the latest/stable versions available in the market. That's where the conflict occurs.Now you must deploy your Java 1.5 codes into a 1.4 Java runtime environment (even may be 1.3 or 1.2). Even if the Java code has not used any of the new features of Java 1.5, you still can not run your code in 1.4 JRE as the runtime throws an error saying "java.lang.UnsupportedClassVersionError". Compile 1.5 codes for 1.4 JVMJava compiler provides an option to specify the target JVM of the generated classes like 1.5, 1.4, and 1.3 as follows.public class MyClass { pu...
