My Final Year project covered Telecoms fraud. It included a call detail record generator.I have had a fair few queries about this, mostly around how to develop a CDR tool.Whilst I have only ever seen one CDR file. I did do a fair amount of research around the subject and I found out quite a bit.Firstly, I choose to store the least amount of data that I could get away with. The data that I chose was:
- Caller (source)
- Callee (destination)
- Call Type (local, national etc)
- Start Time
- The average cost and STDEV of a local call
- The average number and STDEV of local calls
- The average cost and STDEV of a PRS call
- The average number and STDEV of PRS calls
- The average cost and STDEV of a national call
- The average number and STDEV of National calls
- The times most likely to make a call: 8am -5 pm for a business as an example
I lead the Chrome Developer Relations team at Google.
We want people to have the best experience possible on the web without having to install a native app or produce content in a walled garden.
Our team tries to make it easier for developers to build on the web by supporting every Chrome release, creating great content to support developers on web.dev, contributing to MDN, helping to improve browser compatibility, and some of the best developer tools like Lighthouse, Workbox, Squoosh to name just a few.
