Visio to EPS

I spent lots of time finding how to convert Visio drawing to EPS.
There are many complected ways given. Some of them do not produce good vector images.
Here is the tips for easy conversion.

1. Draw Visio figure.
2. Save as Enhanced Metafile (.emf).
3. Download Free (Open source) Metafile to EPS Converter from http://wiki.lyx.org/Windows/MetafileToEPSConverter and Install.
4. Convert your .emf file.
It works perfectly for me!!

Some useful commands for linux and simulation

Sometimes, small things takes long time to resolve. Today, I was creating cbr-traffic. Although, I have done this thing several times before, it took me 30 minutes. I forgot how I did before. I just check the readme file and tried to follow but it didn't work. I didn't check the ~/indep-utils/cmu-scen-gen/cbrgen.tcl file. Thanks, ns-miling list, I found the answer. It's because of the rate_ should be in float.

Rate in this is a bit confusing. But, if we check the cbrgen.tcl, it's clear.

Anyways, the command should be like:

ns cbrgen.tcl -type cbr -nn 30 -seed 29 -mc 8 -rate 100.0 > cbr-x-x.tcl

A very good article about the setdest and traffic generation is here:
