This software is used to predict stock exchange in Vietnam (VN-Index). I used neural network method which has 3 levels, many values of VN-Index and a lot of relation on Vietnam stock market. Furthermore, it can calculate the error value of prediction and may other valuable results.

VoIP has been popular today because it has some functions and utilities to decrease beginning investment cost and is easier to install in advanced system. Asterisk is a opensource product. It is provided freely to design VoIP. My project is similar to a VoIP product.

Increase DataStore on VMware box Hard Drive already isntalled
If you read this review. Do not let Do's quiet way of chatting fool you. I have been in network for 20 years. I have hired many Engineers. I am an Engineer myself . We are extending our team and took a chance with Do. The project was harder than we both thought. I even loss faith and brought many other people to look at it. None of them! Could figure it out or do the job. Do was confident and knows what he knows. He is also personable and what we wanted most of all communication. Any good review would not give Do justice. He also helped us out with a very good client. --- I will be hiring him as much as I can .
