jgamblin Since I have started looking at the Umbrella DNS Popularity List I was interested in seeing how much the data changes day to day. I fired up RStuido and wrote some terrible code but finally got it to work with some help. Yesterday there were 80937 new DNS names on the list that were not on the list … Read more
Recently I started looking at the Umbrella DNS Popularity List and did a blog post about it here. The data seemed valuable and lacking at the same time so I spent my *limited* free time this week learning about R and RStudio. Protip: If you want to play along at home there is an RStudio docker container so all … Read more
Cisco offers a daily list of the million most queried domain names from Umbrella (OpenDNS) users.

So over the weekend and with a lot of help from Clint Wilson I built a … Read more
An amazing mentor and leader I work with has been talking to me recently about what real leadership looks like and shared with me a list of quotes he keeps on his desk that his dad who had a leadership role in the military collected and gave to him. He gave me a copy and said … Read more
I am reading a book called “The Art of Authenticity” and in the book over a couple of chapters it talks about understanding what makes strong leaders and deciding who you should follow. I have pulled these 10 questions out of those chapters: What was your first leadership role? When you think about the process … Read more

The problem is that there are not many good places to search these logs. The best I have found is from Symantec, although it is … Read more

Turns out car hacking … Read more
