Dropped your iPod/Phone in Water–How to fix it?

How to dry your phone or iPod that is been dropped in water or washbasin. Here are the quick step you can follow to make your phone dry.

Before going to the service center, you can try this out as a remedial measure. Sometimes it works perfectly. (you need not even go to the service center for servicing the phone)

Step 1: Once the Phone/iPod/iPhone is dropped in water, try to get it back as soon as possible.

Step 2: Automatically your phone would have been switched off. Else switch it off immediately as the water should not flow inside the circuit board. (Don’t try to charge your phone also, as it may completely damage the phone)

Step 3:  Take a small bowl with rice and keep your phone/iPod inside the bowl containing rice. Rice has the property of absorbing the moisture (no matter how deep the moisture inside the phones). Keep the phone atleast for one full day.

Step 4: After a day, you may switch on the phone and see what happens. The success rate for the phone to work perfectly is 70%. If still the problem persists like your phone/iPod is not switching on, keep it for one more day and  try it. Even after that if it is not working, you may visit the service center for repair.

Two weeks back, I dropped my iPod in a wash basin and the iPod was inside the wash basin for more than an hour. But within 24 hours of rice massage, my iPod is working perfectly fine.

Installing ns-2.29 in Ubuntu 12.04

Off late, we try to use(install) a old software in a new Operating System for want of backward compatibility or to survey.  This following post shows you how to install ns-2.29 in Ubuntu 12.04.

Unlike other ns2 installations, this installation has so many errors, warnings and patchings. Once everything is overcome, ns installs successfully

Step 1: Download and untar ns-2.29 from this link (http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.29/ns-allinone-2.29.3.tar.gz/download)

Step 2: install the necessary dependancy packages using the command "sudo apt-get install build-essential libxmu-dev autoconf automake" (without quotes). This will install the necessary developmental packages

Step 3: Since ns-2.29 is older software, some of the pointer conversion have to be changed inside ns-2.29

Step 4: go to terminal, point to the location of ns-allinone-2.29 using the command "cd ~/ns-allinone-2.29/" and type "./install"

Step 5: there may be the following errors during the installation, please correct one by one

1. OTcl-1.11 error make failed.

for this error, open the file under the folder otcl-1.11/configure.in and go to line number  

Change the following block to 

 Linux*)

        SHLIB_CFLAGS="-fpic"

        SHLIB_LD="ld -shared"

        SHLIB_SUFFIX=".so"

        DL_LIBS="-ldl"

        SHLD_FLAGS=""

        ;;

Linux*)

        SHLIB_CFLAGS="-fpic"

        SHLIB_LD="gcc -shared"

        SHLIB_SUFFIX=".so"

        DL_LIBS="-ldl"

        SHLD_FLAGS=""

        ;;

2. tclcl-1.17 error, in line number 566 of Tcl.cc file (~tclcl-1.17/Tcl.cc) (See the upper case Tcl.cc)

change the following to 

char *p = strchr(localName, '(');

this following line

char *p =const_cast<char*>( strchr(localName, '('));

3. there will be so many errors in the queue/ folder (~ns-allinone-2.29/ns-2.29/queue/), there may be some pointer conversion errors

Error 1:

Step 6: Once the errors are corrected, go back to ns-allinone-2.29 and press ./install and see whether the installation is successful

Step 7: Set the PATH information in /home/pradeep/.bashrc and  execute "source .bashrc"

Check whether ns and nam are working (for me nam was not working, Since mine is ubuntu I installed NAM separately using "sudo apt-get install nam"

Thats all!!!!.
