I’ve been wanting to create a custom MaxMind mmdb file for alternate IPv4 range classifications for a while, and finally had an opportunity to do so for the $DAYJOB. MaxMind mmdb files are small and easy to work with and provide lightning fast lookups. This repo — https://github.com/hrbrmstr/clouds2mmdb — has an R script for pulling… Continue reading
#30DayMapChallenge 2021 Day 2: Lines
The 30-Day Map Challenge is on again, and I’m hoping to be able to scrounge some time to get an entry for each day. Day 2 is lines (Day 1 was posted on Twitter only) and — while I’m hoping to focus on saving U.S. democracy for the majority of the entries, today’s is a… Continue reading
RSwitch 2.1.2b Bug-fix Release
RStudio is continuing to refine their 👍🏽 new product version string scheme, with the most recent change using something like the following for daily builds: RStudio-pro-2021.11.0-daily+23.pro1.dmg The full URL for these Amazon S3-hosted builds is something like: https://s3.amazonaws.com/rstudio-ide-build/desktop/macos/RStudio-pro-2021.11.0-daily%2B23.pro1.dmg with the + getting URL encoded to %2B.

Acoustic: Solving a CyberDefenders PCAP SIP/RTP Challenge with R, Zeek, tshark (& friends)
Hot on the heels of the previous CyberDefenders Challenge Solution comes this noisy installment which solves their Acoustic challenge. You can find the source Rmd on GitHub, but I’m also testing the limits of WP’s markdown rendering and putting it in-stream as well. No longer book expository this time since much of the setup/explanatory bits… Continue reading
Packet Maze: Solving a CyberDefenders PCAP Puzzle with R, Zeek, and tshark
It was a rainy weekend in southern Maine and I really didn’t feel like doing chores, so I was skimming through RSS feeds and noticed a link to a PacketMaze challenge in the latest This Week In 4n6. Since it’s also been a while since I’ve done any serious content delivery (on the personal side,… Continue reading

WWDC 2021 is on this week and many new fun things are being introduced, including some data science-friendly additions to the frameworks that come with Xcode 13 and available on macOS 12+ (and its *OS cousins). Specifically, Apple has made tabular data a first-class citizen with the new TabularData app service. A future post will… Continue reading
