Domain tip of the day:
DERIVATIVE:
Derivative is a product whose value is derived from the value of one or more basic variables, called bases (underlying asset, index, or reference rate), in a contractual manner. The underlying asset can be equity, forex, commodity or any other asset. For example, wheat farmers may wish to sell their harvest at a future date to eliminate the risk of a change in prices by that date. Such a transaction is an example of a derivative. The price of this derivative is driven by the spot price of wheat which is the “underlying”.
Derivative contracts have several variants.The most common variants are Forwards and Futures
Forwards: A forward contract is a customized contract between two entities, where settlement takes place on a specific date in the future at today’s pre-agreed price.
Futures: A futures contract is an agreement between two parties to buy or sell an asset at a certain time in the future at a certain price. Futures contracts are special types of forward contracts in the sense that the former are standardized exchange-traded contracts.
Technical tip of the day:
Mainframe:
When we use SORT for bigger files,we can use DYNALLOC along with sort.This dynamically allocates Sortwork space.
If we handle records in millions using this we can save some execution time.
eg: SORT FIELDS=COPY,DYNALLOC=(SYSDA,255)
Notepad Tip:
This is useful when troubleshooting a problem where you need to record what is happening at specific times:
1)Open notepad
2)Set the first line to be ( as .LOG in uppercase) .LOG
3)press enter and save/close the file
4)Every time you open the file, notepad will automatically insert the system date/time at the end of the file and add a new line where you can begin typing
Math Play:
Mostly we use our cell phone and calculators to do any multiplication.
For a change try this .
When we mulitply any 3 * 3 number maximum number of digits we can get will be 6 and maximum value can be (999 * 999 = 998001).
Let me take this way 123 * 456 = abcdef
eg : 123 *
456
————–
56088
————–
step 1) First step multiply 3 * 6 = 18 ;8 will be moved to’ f ‘ and 1 will be carried over
Step 2) (2 * 6 ) + (3 * 5) =27 add this value with carry over number from step 1= 28 ;8 will be moved to ‘e’ and 2 will be carried over.
Step 3) (1 * 6) + (2 * 5) +(3 * 4) = 28 add this value with carry over from previous step = 28 + 2 = 30 ;0 will be moved to ‘d’ and 3 will be carried over
Step 4) (5* 1) + (2 * 4 ) = 13 ,add carry over from precious step 13+ 3 = 16 ;6 will be moved to ‘C’ and 1 ill be carried over.
Step 5) (1*4 ) = 4, add carry over from previous step 4 + 1= 5 ; 5 will be moved to ‘b’
Step 6) 0 will be moved to ‘a’
IT News:
IBM on Tuesday (April 28 th 2009) launched a new versions of DB2 and InfoSphere Warehouse software.
Code-named ‘Cobra’, the new version of DB2 reduces an even greater amount of space needed to store data, helping clients save up to 75% on related energy costs. The new software includes workload management and autonomic computing features that improve the performance of key applications such as closing quarterly financial reports and helping IT staff more efficiently manage their growing data, leading to a time savings of up to 35%.
The software will also help companies better utilize hardware, improve administration efficiency, easily run applications written from other database software, and generate new intelligence.
Interesting Facts :
1. Asia is home to nearly 80% of the world’s 315m (m-million) motorcycles. About 45m of those are in India, the region’s second-biggest fleet after China, with more than 100m.
2. Sales of two-wheelers in India are running at about 7m a year,outstripping those of cars by nearly five to one.
3. Not even one in a hundred Indians owns a car,but one in 20 owns a two-wheeler (may Nano change this trend).
4. Indian Railways has one of the largest and busiest rail networks in the world, transporting over 18 million passengers and more than 2 million tonnes of freight daily.
5. Indian Railways is the world’s largest commercial or utility employer, with more than 1.4 million employees.
