I saw this on Hacker News this morning and it got me curious as to how many other TLDs (e.g. .com) resolve to an address (i.e. https://uz./ displays a page in your browser since uz. resolves to 91.212.89.8). This is quick work with R ...

UPDATE The statebins package is now available on CRAN

I became enamored (OK, obsessed) with a recent visualization by the WaPo team which @ryanpitts tweeted and dubbed statebins:

Statebins! RT @kevinschaul: States with the most jobs lost or threatened because of trade. https://t.co/r1pJhudpz3 pic.twitter.com/eMozAgyEAb ...

The dtupdate package has functions that attempt to figure out which packages have non-CRAN versions (currently only looks for github ones) and then tries to figure out which ones have updates (i.e. the github version is > local version). It provides an option (not recommended) to auto-update any packages ...

Sometimes you need to get to a command prompt from R, whether it’s to wrangle git on the command line or do some package work. RStudio provides ways to do this from menus and hotkeys, but on OS X it sticks you in Terminal.app. I’m an iTerm ...

Thanks to a blog comment by @arj, I finally ran at least one of the new Rcpp-based through valgrind (resolv) and, sure enough there were a few memory leaks which are now fixed. However, I first ran valgind with a simple test R script that just did library(stats ...

We’ve got some new and updated R packages that are (hopefully) helpful to security folks who are endeavouring to use R in their quest to find and prevent malicious activity. All packages now incorporate a testthat workflow and are fully roxygen-ized and present some best practices in R ...

The R Language is really good at data and statistical analysis, but when it comes to working with information security data it has a few holes that need plugging up. Bob has been doing a couple of posts using Rcpp to do things like Basic DNS Lookups, TXT lookups, and ...

Back in April, we showed you how to use a C resolver library to make many different kinds of DNS lookups. More oft than not, such complete functionality is not necessary, but R still only provides nsl to get an IPv4 address of a given hostname, which is woefully inadequate ...

I’ve been using RStudio’s new ability to run Python scripts since I often need to analyze/process data in R but then run web services with said data in Python (usually via Flask). I’d rather live with the foibles of the RStudio editor than use a separate ...

Bob and I presented at Secure360 together back in May (the slides are available on our site). But during that presentation we played the last Marx video I built in the post titled, “Visualizing countries from the Marx data“. The reaction we got was completely unexpected and many people commented ...
