It’s been about a month since I posted the initial overview and I thought it would be good to post an update of the progress. While I’ve not been able to devote 100% to this project over the last month there have been some significant improvements. The most visible ones are to the web interface. I’ve added a very flexible application level authorization system. I’ve also added an interface for managing one of the key inputs to the system with a protective 2 level approval process. I’ve also been tweaking the scoring system to better handle corner cases as I’ve. . .

I’ve been working on a big new project since just before the new year and it’s starting to take shape and generate useful results. I can’t give away too many details on how exactly it works but I wanted to share this with some of you who are also working in telecom. I was asked to develop a real-time system to identify toll fraud that would work for our entire voip carrier network that currently originates calls from 19 different countries for both residential, SMB, and wireless. For those who. . .

I was invited to be in a focus group for the local talk radio station recently with a focus on how they use email to communicate with listeners.

They wanted feedback on what they are currently doing and opinions on new approaches and services they were thinking of offering. One example that I like.. is that you can tell them what roads you travel for your commute and if there are accidents. . .
What I Do – Broadsoft CDR Files to Radius Accounting Records

As part of a larger project I needed to generate real time radius records from the CDR accounting files of several cluster pairs of Broadsoft application servers. So I wrote a perl script to do just that. It maps the CDR fields to radius attribs and encodes the accounting packet using the Net::Radius::Packet CPAN module. In my case I’m using the Radiator radius server from OSC Software on the other end with lots of custom ‘hook code’ to clean up and store the call. . .

I’ve been working on giving the site a facelift lately.. trying to make it a little more ‘light’… how am I doing? I’ll also be rotating in various photos I’ve taken in the page header. I’ll try to stick to photos I’ve actually taken myself… maybe as an incentive to do more traveling. I’m also trying out apache alternatives.. first lighttpd with fastcgi then nginx.

I’ve written before about the world being held together by duct tape… and it seems there are more people lately who have decided to rip off the covers and go looking for some duct tape. The latest headline comes from the world of SCADA systems. Researchers Lay Bare Woeful SCADA Security. SCADA systems are small embedded computers that help guide various kinds of industrial processes..manufacturing, power plants and water systems. Basically anything where you have sensors, motors, pumps etc that have. . .
