Save Enviornment - save yourself......

Save Enviornment, Save Earth, Save Planet, Save animals, Save humans and what not. Are these just slogans derived some crazy people....... NO NO and NO.....

Wake up all you,,, yes all you out there or we will be in a never ending sleeps.

Ignorance of people(no I am not talking about those so called illitrate people), I am talking about those people who call them educated yet they seem to be totally ignorant about these issues.

Issues on which our entire human race is dependant.... please read the following article and follow and make other follow:

Ways to Conserve

-Turn off the lights and fans when you leave the house to save electricity.

-Turn off your car when waiting in a carpool line. This decreases emissions and saves petrol.

-As your incandescent light bulbs burn out, replace them with fluorescent ones. Compact fluorescent bulbs use 75% less energy than incandescent ones. While they are more expensive, they last years longer.

-Turn off the water when you shave or brush your teeth. On this I would like to further add on and request all my office collegues(in fact in all offices) to turn off the water when they wash their face or give their hair a "TOM CRUISE" look. I feel real bad people inspite of this water crises use water in Office Toilets as if they are on a River Bank.

Please grow up put that running tap off. Also I have seen people using tissue papers as if its made out of nothing. Wake up all you,, that humble looking tissue paper has been the reason of many tree cuts. Use one paper towel when you wash your hands in the public restroom. Or better yet, let your hands air-dry.

I URGE all offices(private or public), cinema halls, auditoriums, train/bus stations, airports and all other public places to put a graphic NOTICE or WARNING sign boards showing what harm we are posing on environment(read environment as humans) by not using paper towels and water wisely.

Please visit back for more....and put your comments, suggestions, ideas on this and help in saving this planet. JOIN HANDS

Different Mobile Technologies

This post is for my MOM and alike who always are confused about different mobile technologies. Those were the days back in 1980’s when the mobiles were big enough to break someones head to this era of smart phones that fits easily in palm; mobiles have come a long way.

But how many of us really know how this tiny little masterpiece can call someone across the world

The first generation (1G) of mobile communications was introduced in the late 1970s (I was not there then :) ; used for voice transfer. Then in 1990s, second generation (2G) systems came into existence and was further developed to 2.5G, which includes GSM, TDMA and CDMA. These were used for voice and data.

The next generation of mobile communications is 3G and this delivers data speeds from 384 kbps to 2 Mbps and over wireless interfaces such as GSM, TDMA and CDMA.

Jargon Bustor:
Frequency division multiple access (FDMA)
The first-generation analog mobile access method; FDMA uses separate frequencies for each call. For example if there are four stations, each will receive their own frequency. Thus there is no interference between them. This reduces interference, but limits the number of users.

Time division multiple access (TDMA)
TDMA allocates unique time slots to each user within each channel, thus allowing many users to access the radio frequency without anyone's interference. Each mobile conversation uses only a particular frequency slot of the time.

Code division multiple access (CDMA)
Commercially introduced in 1995 by Qualcomm, CDMA quickly became one of the world's fastest-growing wireless technologies. 3G CDMA networks provide more capacity for voice traffic, along with high-speed data capabilities, hence many cellular service providers are now building or upgrading to it.
CDMA is used in both 2G and 3G wireless technologies. Indian Cell operators like Reliance IndiaMobile, TATA Indicom, BSNL and MTNL's Garuda all use CDMA2000 technology and its variant CDMA1x.

Global system for mobile communications (GSM)
Developed on TDMA protocol in Europe, GSM is now the worldwide standard technology for mobile communications. The advantage of GSM is that it provides a high level of security, globally accepted technology standards and superior sound quality.
For any GSM phone to work, it requires a Subscriber Identity Module (SIM), a card that contains your telephone account information. Thus, an Indian GSM phone can be used in USA and other countries too.

What is GPRS?GPRS, short for General Packet Radio Services, is an enhancement to GSM technology that integrates GSM and IP technology. GPRS offers an always-on, high speed connectivity to the Net. Thus you can check your email on the move and surf the Web at high speeds.

What is WAP?
In this hi-tech age, people on the move need any-time access to the Net. This is where WAP comes in. It provides Internet access to cell phones. It is an open standard for wireless protocols that is independent of the service providers. To display Web content, the cell phone must have a WAP browser. Nowadays, cell phones often come with WAP and GPRS technology.
WAP and GPRS also allows you to download games, send mail and even transfer your messages to your PC.

What is EDGE?
The new EDGE ((Enhanced Data GSM Environment) interface has been developed specifically to meet the bandwidth needs of 3G. Promoted by Ericsson, it offers high-speed data transfers over GSM networks with just a software upgrade to the handset. EDGE allows speeds up to 384 kbps.

VoIP

Recently in the very sad event of Mumbai blast, there was a lot of buzz about VoIP technology being used by the terrirost to keep connected with there masterminds somewhere in PAK. A very sad event of seeing such a misuse of technology.

So What is VoIP: VoIP stands for Voice over Internet Protocol, which is phone sevice that uses broadband Internet connectivity to dial. Some VoIP services may only allow you to call other people using the same service, but others may allow you to call anyone who has a telephone number - including local, long distance, mobile, and international numbers. Also, while some VoIP services only work over your computer or a special VoIP phone, other services allow you to use a traditional phone connected to a VoIP adapter.

How it works: According to wikipedia, VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs which encode speech allowing transmission over an IP network as digital audio via an audio stream. To put in simpler manner, VoIP services convert your voice into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is converted to a regular telephone signal before it reaches the destination. VoIP can allow you to make a call directly from a computer, a special VoIP phone, or a traditional phone connected to a special adapter.


What you need: A broadband (high speed Internet) connection is required. This can be through a cable modem, or high speed services such as DSL or a local area network. A computer, adaptor, or specialized phone is required. Some VoIP services only work over your computer (with its software a a microphone) or a special VoIP phone (that plug directly into your broadband connection and operate largely like a traditional telephone), while other services allow you to use a traditional phone connected to a VoIP adapter.

Reset Text Boxes in ASP.Net - Part 2

In my last Article "Reset Text Boxes in ASP.Net" I suggested a way to clear all text boxes in ASP.NET form(C#). But in real time situation life is not that easy and we are faced with more than just text boxes. So this time I'll show how to clear some of the very comman controls on a ASP.NET form.

C#

private void ClearForm(Control parent)
{
foreach (Control ctl in parent.Controls)
{
if (ctl.Controls.Count > 0)
{
ResetFormControlValues(ctl);
}
else
{
switch(ctl.GetType().ToString())
{
case "System.Web.UI.WebControls.TextBox":
((TextBox)ctl).Text = "";
break;
case "System.Web.UI.WebControls.CheckBox":
((CheckBox)ctl).Checked = false;
break;
case "System.Web.UI.WebControls.RadioButton":
((RadioButton)ctl).Checked = false;
break;

}
}
}
}

VB.NET

PrivateSub ClearForm(ByVal parent As Control)
ForEach ctl As Control In parent.Controls
If ctl.Controls.Count > 0 Then
ResetFormControlValues(ctl)
Else
SelectCase ctl.GetType().ToString()
Case"System.Web.UI.WebControls.TextBox"
CType(ctl, TextBox).Text = ""
Case"System.Web.UI.WebControls.CheckBox"
CType(ctl, CheckBox).Checked = False
Case"System.Web.UI.WebControls.RadioButton"
CType(ctl, RadioButton).Checked = False
EndSelect
EndIf
Next ctl
End Sub

Hey!! this can also be done through JavaScript.... but that in the next post.. so plz join again.
Hope that helps you all, please comment if any more to add, improve or anything.
