Wrapping Up Exploration of John Deere’s MowerPlus Database

June 9, 2019 | hrbrmstr

I did another twitter thread on the aforeblogged MowerPlus database as I explored the tables after a second mow to determine what identified a unique mowing “session” (using John Deere’s terms). This is the thread: As forewarned, today was the second mow with the new @JohnDeere mower. I'll thread ...

Reader Challenge: Have Some Fun with Apple’s WWDC 2019 Keynote Subtitles & Show Your Work

June 7, 2019 | hrbrmstr

I was pretty brutal to Apple earlier this week in a Twitter thread that I tried to craft so it occurred in-line with the WWDC live stream (which might be something you want to remember as/if you read on). I really don’t care about “memojis” and I have ...

Make Multi-point “dumbbell” Plots in ggplot2

June 6, 2019 | hrbrmstr

A user of the {ggalt} package recently posted a question about how to add points to a geom_dumbbell() plot. For now, this is not something you can do with geom_dumbbell() but with a bit of data wrangling you can do this in a pretty straightforward manner with just ...

Trawling Through iOS Backups For Treasure (a.k.a. How to fish for target files in iOS backups) with R

June 2, 2019 | hrbrmstr

In a recent previous post I brazenly talked over the “hard parts” of how I got to the target SQLite file that houses “mowing history” for what has become my weekend obsession. So, we’ll cover just how to do that (find things in iOS backups) in this post along ... [Read more...]

Quick Hit: Handling Cocoa Core Data Timestamps in R

June 1, 2019 | hrbrmstr

For the first time ever we got a new riding mower this weekend. We’ve always haggled to keep the one sellers were using with any given house we’ve purchased over the years (that was big enough for a yard that “requires” a riding mower). We ended up getting ... [Read more...]

Making a Command Line HTML Rendering Script for “The Art of the Command Line” (in R)

May 31, 2019 | hrbrmstr

The Feedly category I have setup for git-stalking has indicated a fairly massive interest in Joshua Levy’s The Art of the Command Line. What is “The Art of the Command Line”? To quote the author(s): Fluency on the command line is a skill often neglected or considered arcane, ...

Two New Ways to Make DNS over HTTPS Queries in R

May 26, 2019 | hrbrmstr

A fair bit of time ago the {gdns} package made its way to CRAN to give R users the ability to use Google’s (at that time) nascent support for DNS over HTTPS (DoH). A bit later on Cloudflare also provided a global DoH endpoint and that begat the (not-on-CRAN) {... [Read more...]

Add Dressbarn to the Continued Retailpocalypse

May 21, 2019 | hrbrmstr

I’ve talked about the retailpocalypse before and this morning I was greeted with the news about Dressbarn closing all 650 stores as I fired up a browser. I tweeted some pix and data but not everyone is on Twitter so I’m just posting a blog-blurb here with the code ...

Mapping Tornado Alley with R

May 18, 2019 | hrbrmstr

I caught a re-tweet of this tweet by @harry_stevens: THREAD: I wrote a post on @observablehq about a map I made today. It shows a typical day in the life of a graphics journalist: You never know what problems you'll have to solve on deadline! https://t.co/yRhW1...

Quick Hit: Updates to QuickLookR and {rdatainfo}

May 12, 2019 | hrbrmstr

I’m using GitUgh links here b/c the issue was submitted there. Those not wishing to be surveilled by Microsoft can find the macOS QuickLook plugin project and {rdatainfo} project in SourceHut and GitLab (~hrbrmstr and hrbrmstr accounts respectively). I hadn’t touched QuickLookR???? or {rdatainfo}???? at all since 2016 ...

Quick Hit: Scraping javascript-“enabled” Sites with {htmlunit}

April 27, 2019 | hrbrmstr

I’ve mentioned {htmlunit} in passing before, but did not put any code in the blog post. Since I just updated {htmlunitjars} to the latest and greatest version, now might be a good time to do a quick demo of it. The {htmlunit}/{htmunitjars} packages make the functionality of the ...

Lost In [SQL] Translation: Charting d[b]plyr Mapped SQL Function Support Across All Backends

April 10, 2019 | hrbrmstr

Like more posts than I care to admit, this one starts innocently enough with a tweet by @gshotwell: Is there a reference document somewhere of which dplyr commands work on various database backends? #rstats — Gordon Shotwell (@gshotwell) April 9, 2019 Since I use at least 4 different d[b]plyr backends every week, ...

A Limited-but-Functional Couchbase Free Text Search & Retrieval Un-package; or, “How I Abused Couchbase & R to Perform Bulk IP Whois Full-text Searches” (a Cobbler’s Tale)

April 7, 2019 | hrbrmstr

Researching “the internet” (i.e. $DAYJOB) means having to deal with a ton of “unique” (I’m being kind) data formats. This is ultimately a tale of how I performed full-text searches across one of them. It all started off innocently enough. This past week I need to be able ...

Wicked Fast, Accurate Quantiles Using ‘t-Digests’ in R with the {tdigest} Package

April 3, 2019 | hrbrmstr

@ted_dunning recently updated the t-Digest algorithm he created back in 2013. What is this “t-digest”? Fundamentally, it is a probabilistic data structure for estimating any percentile of distributed/streaming data. Ted explains it quite elegantly in this short video: Said video has a full transcript as well. T-digests have been ... [Read more...]

Rome Was Not Built In A Day But widgetcard Was!

I saw a second post on turning htmlwidgets into interactive Twitter Player cards and felt somewhat compelled to make creating said entities a bit easier so posited the following: Wld this be useful packaged up, #rstats?https://t.co/sfqlWnEeJVhttps://t.co/troKzmzTNv (TLDR/V: Single function to turn an ...

Assumptions Matter More Than Dependencies

March 18, 2019 | hrbrmstr

There’s been alot of talk about “dependencies” in the R universe of late. This is not really a post about that but more of a “really, don’t do this” if you decide you want to poke the dependency bear by trying to build a deeply flawed model off ... [Read more...]

Handling & Sharing PCAPs Like a Boss with PacketTotal

March 17, 2019 | hrbrmstr

The fine folks over at @PacketTotal bequeathed an API token on me so I cranked out an R package for it to enable more dynamic investigations work (RStudio makes for an amazing incident responder investigations console given that you can script in multiple languages, code in C[++], and write documentation ...

Collecting Content Security Policy Violation Reports in S3 (‘Effortlessly’/’Freely’)

March 14, 2019 | hrbrmstr

In the previous post I tried to explain what Content Security Policies (CSPs) are and how to work with them in R. In case you didn’t RTFPost the TLDR is that CSPs give you control over what can be loaded along with your web content and can optionally be ... [Read more...]

Wrangling Content Security Policies in R

March 10, 2019 | hrbrmstr

(header image via MDN Web Docs) The past two posts have used R to look at the safety/security (just assume those terms are in scare quotes from now on in every post) of web-y thing-ys. We’ll continue that theme with this post where we focus on a [sadly ...
