Brim Security maintains a free, Electron-based desktop GUI for exploration of PCAPs and select cybersecurity logs: along with a broad ecosystem of tools which can be used independently of the GUI. The standalone or embedded zqd server, as well as the zq command line utility let analysts run ZQL (a domain-specific query language) queries on… Continue reading
Horrible puns aside, hopefully everyone saw the news, earlier this week, from @thomasp85 on the evolution of modern typographic capabilities in the R ecosystem. Thomas (and some cohorts) has been working on {systemfonts}, {ragg}, and {textshaping} for quite a while now, and the — shall we say tidyglyphs ecosystem — is super-ready for prime time….

Presented without much commentary since I stopped once {ggrepel} and {graphlayouts} failed (RStudio doesn’t support it yet, either, which I knew). The following steps will get you a fully working and STUPID FAST fully native ARM64 M1/Apple Silicon R setup with {tidyverse} and {rJava}. Just remember, that if you need RStudio (or anything that links… Continue reading
If you’ve been following me around the internets for a while you’ve likely heard me pontificate about the need to be aware of and reduce — when possible — your personal “cyber” attack surface. One of the ways you can do that is to install as few applications as possible onto your devices and make… Continue reading
I was chatting with a fellow Amazon Athena user and the topic of using Presto functions such as approx_distinct() via {d[b]plyr} came up and it seems it might not be fully common knowledge that any non-already translated function is passed to the destination intact. That means you can just “use” approx_distinct() and it will work… Continue reading
The past two posts have (lightly) introduced how to use compiled Swift code in R, but they’ve involved a bunch of “scary” command line machinations and incantations. One feature of {Rcpp} I’ve always 💙 is the cppFunction() (“r-lib” zealots have a similar cpp11::cpp_function()) which lets one experiment with C[++] code in R with as little… Continue reading
The previous post introduced the topic of how to compile Swift code for use in R using a useless, toy example. This one goes a bit further and makes a case for why one might want to do this by showing how to use one of Apple’s machine learning libraries, specifically the Natural Language one,… Continue reading
