Media is abuzz with the latest Aakash

tablet. Dubbed as the “world's cheapest tab-

let”.

With the Aakash tablet, the Indian

government aims to bridge gap between the

rural India and the ongoing technology

boom. The government will provide the tab-

let at a subsidised price of Rs. 1,730 to the

students. The retail version, UbiSlate, will be

available at Rs. 2,999. The ultra low cost of

the device has been grabbing the eyeballs

worldwide.

There are two versions of the Aakash

tablet. The subsidised Aakash tablet will miss

few features such as inbuilt cellular modem

and SIM to access Internet. The retail version

is likely to sport full-fledged specs as an-

nounced by the government. UbiSlate will

come with an unlimited mobile Internet at

Rs.98/month.

Let’s have a look at the specs offered by the

Aakash tablet.

• The Aakash is a seven-inch tablet, run-

ning Android 2.2 Froyo operating system.

• It has a seven-inch 800x400 resistive

touchscreen and is powered by 366 MHz

+ HD video co-processor.

• The tablet comes with a 2GB of storage

memory, which can be extended up to

32GB via microSD.

• It has a 256 MB RAM.

• The device supports document formats:

DOC, DOCX, PPT, PPTX, XLS, XLSX, ODT,

ODP and can run PDF viewer, Text editor.

• It has a 2,100 mAh battery which is

promised to give 3 hours of backup de-

pending upon usage.

• For connectivity, the device supports Wi-

Fi and can connect a datacard for 3G and

GPRS.

A faster and enhanced version of the

low-cost tablet PC, Aakash would be

launched next month (April) without increase

in cost.

“The new tablet’s better specifica-

tions that include 3200mAH battery with 3

hour battery backup, 700 MHz Cortex A8

processor and a capacitive touch screen have

been required to get over the earlier issues

observed in the tablets,” Sibal said.

The first stage of 100,000 tablets was

aimed for higher technical educational insti-

tutions’ students hence to add more techni-

cal feedback on usability and operation of the

tablet.

We are all engineering students. the

living Indian legend in C, C++ once said that all

software engineering students must start

their programming studies with C, otherwise

you will feel difficulty in understanding new

technologies and languages. This statement is

absolutely true in all perspective. So 'C' be-

come a key language for us .

As we all know , 'C' was evolved from

ALGOL,BCPL and B by Dennis Ritchie in 1972.

Obviously this legendary language is going to

celebrate its 40th

birthday soon. Do you know

what makes this language so precious about

the last 4 decades? the one and only one an-

swer is its indomitable speed!!!!. 'C' is well

known for its incredible speed as 'JAVA' for its

portability. It is many times faster than

'VB' .For example a program to increment a

variable from 1 to 15000 will take about 1

second in C while it takes more than 50 sec-

onds in VB.

It will be pretty interesting, checking

the above statement in light of a simple 'c'

program. For that you need to know the

TIME MANAGEMENT techniques used in c. So

my first program describes the key functions

of time management in 'C'.

#include<stdio.h> #include<conio.h> #include<time.h> void main() { time_t c; //time_t is a typedef defined in time.h struct tm *l; //defined in time.h c=time(NULL); I=localtime(&c); printf("it is now.......%s\n",asctime(l)); getch(); }

This program will take the current time

from system and will print on the screen in

ASC format.Iam purposefully avoiding the

working of these commands because I wish

those who are interested in this topic will

learn it from turbo c++ help. Now we can

write a small program to check how much

time 'C' will take to increase a number from 1

to 15000.

#include<stdio.h> #include<conio.h> #include<time.h> void main() { int i,j=1; time_t st_t,end-t; st_t=time(NULL); for(i=0;i<15000;i++) { j++; } end_t=time(NULL); float diff; diff=difftime(end_t,st_t); printf("it took %dseconds to complete the loop",int(diff)); getch(); }

If you like it ,try it yourself. BEST OF

LUCK..................!!!!!!!!.

Open Source Software Open source refers to a program or

software in which the source code (the

form of the program when a programmer

writes a program in a particular program-

ming language) is available to the general

public for use and/or modification from its

original design free of charge.

Open source code is typically cre-

ated as a collaborative effort in which pro-

grammers improve upon the code and

share the changes within the community.

The rationale for this movement is

that a larger group of programmers not

concerned with proprietary ownership or

financial gain will produce a more useful

and bug-free product for everyone to use.

The concept relies on peer review to find

and eliminate bugs in the program code, a

process that commercially developed and

packaged programs do not employ.

The basics behind the Open Source

Initiative is that when programmers can

read, redistribute and modify the source

code for a piece of software, the software

evolves. Open source sprouted in the tech-

nological community as a response to pro-

prietary software owned by corporations.

Proprietary software is privately

owned and controlled. In the computer in-

dustry, proprietary is considered the oppo-

site of open. A proprietary design or tech-

nique is one that is owned by a company. It

also implies that the company has not di-

vulged specifications that would allow

other companies to duplicate the product.

The Open Source Initiative (OSI)

Open Source is a certification stan-

dard issued by the Open Source Initiative

(OSI) that indicates that the source code

of a computer program is made available

free of charge to the general public. OSI

dictates that in order to be considered

"OSI Certified" a product must meet the

following criteria:

• The author or holder of the license of

the source code cannot collect royalties

on the distribution of the program.

• The distributed program must make

the source code accessible to the user.

• The author must allow modifications

and derivations of the work under the

program's original name.

• No person, group or field of endeavor

can be denied access to the program.

• The rights attached to the program

must not depend on the program's being

part of a particular software distribution.

The licensed software cannot place re-

strictions on other software that is dis-

tributed with it.

Business Intelligence Software

Business intelligence software

(also called BI software) is software that

is designed specifically to analyze all the

business data, through automated proc-

esses, to provide a better understand an

organization's strengths and weak-

nesses. It is the organization's business

intelligence software that allows man-

agement to better see the relationship

between different data for better deci-

sion-making and deployment of re-

sources. Business Intelligence software

plays a key role in the strategic planning

process of the corporation.

In many ways business intelli-

gence is a catch-all phrase as it does not

refer to one single type of analysis or

data, but rather it represents a variety

of methodologies, technologies, and

software applications and tools to or-

ganize and analyze all of a businesses'

data.

The phrase business intelligence

(BI for short) is the combination of soft-

ware applications, methodologies and

business systems that play a key role in

the strategic planning process of a cor-

poration.

Most companies collect huge

amounts of data from its business op-

erations. Keeping track of that informa-

tion requires a wide range of software

programs and different database appli-

cations for various departments (e.g.

sales, finance, supply) throughout the

organization to access and use the

data.

Business intelligence software is

often referred to as business intelli-

gence tools (BI tools) representing a

number of software applications that

integrate to provide the means to re-

port, analyze and then present the

data. Business intelligence software is

also designed to use data that is stored

by the business in a any type of data

storage system or data warehouse.

The types of tools that make up a busi-

ness intelligence software application

solution generally include tools for

spreadsheets, operational dashboards,

data mining, reporting, search (query),

analytics processing (OLAP), content

viewer, and other components of en-

terprise resource planning (ERP) sys-

tems. Often, business intelligence soft-

ware may also integrate tools designed

for specific verticals, such as retail,

healthcare or education.

TipsandTricks

Google Search

There are a lot of pages on the Inter-

net, billions and billions of them. When you

go to search for a topic, you often get millions

of hits listed. It is very easy for a worthwhile

site to get buried so far down in a search that

you will never see it. So when you want to do

a search, it pays to do whatever you can to

narrow down the hits that will be displayed.

That’s where search operators come

in. By adding certain terms to a search, you

can filter out a lot of irrelevant stuff and have

a better chance of finding what you are look-

ing for. There are a number of Google opera-

tors.

SOME OF THE OPERATORS ARE :

• Site:

To limit a search to a particular site some-

link.com, add the term site:somelink.com to

your search query.

For example, Microsoft is often the authentic

and best source for Windows information.

Microsoft does have a search facility but

Google has done a better job of indexing Mi-

crosoft articles than Microsoft. So when look-

ing for Windows material add a term

site:microsoft.com to the search.

• Intitle:/allintitle:

If you are pretty sure that a certain word or

string is included in the title of a page you are

looking for, you can limit the search by using

the term intitle:someword. You can look for

several words with a term allintitle:word1

word2.

For example to find pages with the words

“windows command tips” in the title use the

search allintitle:windows command tips.

Note that the words do not have to appear

grouped together in the actual page title

• Inurl:/allinurl:

This is similar to the above operator but

looks for words or strings contained in the

URL rather than the page title. With allinurl,

you can search for words that are in differ-

ent parts of the URL.

For example, allinurl: google faq would find

links such as google.com/help/faq.html.

• Filetype:

If you are looking for a particular kind of file

rather than an HTML page, use the operator

filetype:extension

For example to find PDFs, use filetype:pdf

When you first install Windows

7, it asks for your language, time and

currency. This information is then used

to configure the system, including set-

ting up which Windows themes are

available. The themes vary according to

your geographical location. For exam-

ple, if you tell the computer you are in

the United States, , the available desk-

top backgrounds and themes will in-

clude a selection with scenery from lo-

cations such as Maine, the Southwest

and so on.

English is a major language – Mi-

crosoft has chosen Australia, Canada,

Great Britain and South Africa. But

these other selections are hidden and

not normally accessible. They are in the

folder \Windows\Globalization\MCT

with subfolders MCT-AU, MCT-CA, MCT

-GB, MCT-US, and MCT-ZA . Each sub-

folder has wallpapers for a specific

country: AU for Australia, CA for Can-

ada, GB for Great Britain, US for the

United States, and ZA for South Africa.

Here is how to install and use them:

• Open the Start menu and in the

search box, type

%WinDir%\Globalization\MCT

• Then press Enter. Note that if you

don’t pressEnter, you will probably

see the message “No items match

your search”. The window shown in

figure 1 will open

• Each country folder contains an-

other folder with the name of the

country. This subfolder contains

background images that can be used

for wallpaper. There is also a sub-

folder for themes.

• Choose the country you are inter-

ested in and open the subfolder

called Theme. Double-click the

theme you see inside there and a

shortcut to the theme will be in-

stalled in the Personalization section

of Control Panel.
