Display Message During Windows Startup

If you use a company-owned PC, you may have seen a legal notice displayed before you sign in to Windows. Here’s how you can do the same thing on your own PC and display a message with any text you want. If you’re willing to dive into the Windows Registry or Local Group Policy Editor, there are some interesting things you can do surrounding Windows sign in.  If you have a Home edition of Windows, you will have to edit the Windows Registry to make these changes. You can also do it this way if you have Windows Pro or Enterprise, but just feel more comfortable working in the Registry. (If you have Pro or Enterprise, though, we recommend using the easier Local Group Policy Editor, as described in the next section.) Standard warning: Registry Editor is a powerful tool and misusing it can render your system unstable or even inoperable. This is a pretty simple hack and as long as you stick to the instructions, you shouldn’t have any problems. Open the Registry Editor by hitting Sta...

NS2 trace analysis IN MATLAB

Hey, In this post we are discussing about  How to do ns2 trace analysis under Matlab using Tracegraph Tool The following procedure shows the way to do trace analysis under Matlab using the Tracegraph tool : About Software versions used : We can use ns2.35 for the proposed simulation (even it will run under some lower versions also). We are using the new version of Tracegraph Version 2.05.  We are using the new version of Trace Converter Version 1.01. We can get it from the following link:  http://www.tracegraph.com/trconvertwin.zip Matlab 6.5 can be used to run the source version of Tracegraph. We will use a trace converter because Tracegraph could not handle the trace file generated by the wired cum wireless scenario. Refer Internet for further information about Tracegraph and trace converter. Diagram Explaining the Simulation and Analysis Steps. The highlighted model (Case – 4)  in the following diagram shows the simulation and analysis using we are using in t...

NS2 UNINSTALLATION IN LINUX

 1) Delete the directory  ns-allinone-2.35. 2) Delete all ns2 related files from bin folder:   /usr/local/lib 3) After completing the deletion type the following command in the command window      gedit ~/.bashrc 4) Now an editor window appears,please remove following codes from bash file (note that '/home/abhiram/Desktop/ns-allinone-2.35/octl-1.14' in each line in the below code  varies with your location ) # LD_LIBRARY_PATH OTCL_LIB=/home/abhiram/Desktop/ns-allinone-2.35/otcl-1.14 NS2_LIB=/home/abhiram/Desktop/ns-allinone-2.35/lib X11_LIB=/usr/X11R6/lib USR_LOCAL_LIB=/usr/local/lib export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_LIB:$USR_LOCAL_LIB # TCL_LIBRARY TCL_LIB=/home/abhiram/Desktop/ns-allinone-2.35/tcl8.5.10/library USR_LIB=/usr/lib export TCL_LIBRARY=$TCL_LIB:$USR_LIB # PATH XGRAPH=/home/abhiram/Desktop/ns-allinone-2.35/bin:/home/abhiram/Desktop/ns-allinone-2.35/tcl8.5.10/unix:/home/abhiram/Desktop/ns-allinone-2.35...
