| 0:00.0 | Hello and welcome to the Friday, January 9th, 2026 edition of the Sands Inlet Storm Center's Stormcast. |
| 0:12.6 | My name is Johannes Ulrich, and today I'm recording from Jacksonville, Florida. |
| 0:17.5 | And this episode is brought you by the sands.edu undergraduate certificate program in applied cyber security. |
| 0:25.5 | Well, one of the challenges that we are always faced with when we're looking at all of our honeypot data is that, well, how do we summarize it? |
| 0:33.6 | How do we find patterns in the data? |
