Quick Hit: Comparison of “Whole File Reading” Methods

August 7, 2020 | hrbrmstr

(This is part 1 of n posts using this same data; n will likely be 2-3, and the posts are more around optimization than anything else.) I recently had to analyze HTTP response headers (generated by a HEAD request) from around 74,000 sites (each response stored in a text file). They look ... [Read more...]

Aligning the Dots On COVID Prison Waffles

July 24, 2020 | hrbrmstr

The Marshall Project has a solid story and set of visualizations on the impact of COVID-19 in U.S. prisons. They keep the data (and vis) regularly updated. They do great work and this is an important topic, but this visualization breaks my “ordered grid” OCD: To be fair, it’...

A Look at PAN-OS Versions with a Bit of R

July 10, 2020 | hrbrmstr

The incredibly talented folks over at Bishop Fox were quite generous this week, providing a scanner for figuring out PAN-OS GlobalProtect versions. I’ve been using their decoding technique and date-based fingerprint table to keep an eye on patch status (over at $DAYJOB we help customers, organizations, and national cybersecurity ...

{sergeant} 0.9.0 Is On Its Way to CRAN Mirrors!

June 1, 2020 | hrbrmstr

Tis been a long time coming, but a minor change to default S3 parameters in tibbles finally caused a push of {sergeant} — the R package that lets you use the Apache Drill REST API via {DBI}, {dplyr}, or directly — to CRAN. The CRAN automatic processing system approved the release just ... [Read more...]

Mining R 4.0.0 Changelog for Nuggets of Gold: #1 stopifnot()

May 19, 2020 | hrbrmstr

R 4.0.0 has been out for a while, now, and — apart from a case where merge() was slower than dirt — it’s been really stable for at least me (I use it daily on macOS, Linux, and Windows). Sure, it came with some headline-grabbing features/upgrades, but I’ve started looking ...

Attach Your R Code To Charts You Tweet For Reproducible R Tweets!

May 16, 2020 | hrbrmstr

I caught this tweet by Terence Eden about using Twitter image alt-text to “PGP sign” tweet and my mind immediately went to “how can I abuse this for covert communications, malicious command-and-control, and embedding R code in tweets?”. When you paste or upload an image to tweet (web interface, at ... [Read more...]

New Package — {cdccovidview} — To Work with the U.S. CDC’s New COVID-19 Trackers: COVIDView and COVID-NET

April 11, 2020 | hrbrmstr

The United States Centers for Disease Control (CDC from now on) has setup two new public surveillance resources for COVID-19. Together, COVIDView and COVID-NET provide similar weekly surveillance data as FluView does for influenza-like illnesses (ILI).

{uaparserjs} Updated on CRAN & Using webpack to Make {V8} Application Bundles

April 1, 2020 | hrbrmstr

Just a quick note that thanks to a gentle nudge an updated version of {uaparser} — a package that processes User Agent strings web clients send to servers — is making its way to all the CRAN mirrors and is also available on CINC. The most significant change is a much overdue ... [Read more...]

The Waffle House Index

March 26, 2020 | hrbrmstr

Waffle House announced it was closing hundreds of stores this week due to SARS-Cov-2 (a.k.a COVID-19). This move garnered quite a bit of media attention since former FEMA Administrator Craig Fugate used the restaurant chain as both an indicator of the immediate and overall severity of a natural ...

{catchpole} Redux and Hashing Files & Websites with {ssdeepr}

March 4, 2020 | hrbrmstr

Über Tuesday has come and almost gone (some state results will take a while to coalesce) and I’m relieved to say that {catchpole} did indeed work, with the example code from before producing this on first run: If we tweak the buffer space around the squares, I think the ...

Make WSJ-esque Über Tuesday Democrat Delegate Cartograms in R with {catchpole}

March 2, 2020 | hrbrmstr

For folks who are smart enough not to go near Twitter, I’ve been on a hiatus from the platform insofar as reading the Twitter feed goes. “Why” isn’t the subject of this post so I won’t go into it, but I’ve broken this half-NYE resolution on ...

BIMI Up, Scotty! A look at Brand Indicators for Message Identification (BIMI) Adoption with R and the Alexa Top 1m

February 21, 2020 | hrbrmstr

It seems that the need for MX, DKIM, SPF, and DMARC records for modern email setups were just not enough acronyms (and setup tasks) for some folks, resulting in the creation of yet-another-acronym — BIMI, or, Brand Indicators for Message Identification. The goal of BIMI is to “provide a mechanism for ...

Prying “.R” Script Files Away from Xcode (et al) on macOS

February 6, 2020 | hrbrmstr

As the maintainer of RSwitch — and developer of my own (for personal use) macOS, iOS, watchOS, iPadOS and tvOS apps — I need the full Apple Xcode install around (more R-focused macOS folk can get away with just the command-line tools being installed). As an Apple Developer who insanely runs the ... [Read more...]

Monitoring Website SSL/TLS Certificate Expiration Times with R, {openssl}, {pushoverr}, and {DT}

January 29, 2020 | hrbrmstr

macOS R users who tend to work on the bleeding edge likely noticed some downtime at this past weekend. Part of the issue was an SSL/TLS certificate expiration situation. Moving forward, we can monitor this with R using the super spiffy {openssl} and {pushoverr} packages whilst also generating a ...

Convert Apple Card PDF Statements to Tidy Data (i.e. for CSV/Excel/database export)

January 13, 2020 | hrbrmstr

I saw this CNBC article on an in-theory browser client-side-only conversion utility for taking Apple Card PDF statements and turning them into CSV files. Since I (a) never trust any browser or site and (b) the article indicated that there is a $5 fee to avoid the “single random transaction removal”, ... [Read more...]

Writing Frictionless R Package Wrappers — Introduction

January 1, 2020 | hrbrmstr

The R language and RStudio IDE are a powerful combination for “getting stuff done”, and one aspect of R itself that makes it especially useful is the ability to use it with other programming languages via a robust foreign language interface capability1. The term “foreign language” refers to another programming ... [Read more...]

Short Attention Span Theatre: Reproducing Axios’ “1 Big Thing” Google Trends 2019 News In Review with {ggplot2}

December 27, 2019 | hrbrmstr

I woke up to Axios’ “1 Big Thing” ridgeline chart showing the crazy that was the 2019 news cycle: and, I decided to reproduce it in {ggplot2}. Getting The Data First, I had to find the data. The Axios chart is interactive, so I assumed the visualization was built on-load. It was, ...
