Mennonite-raised. I get told "no" a lot. I'm finishing a math degree I started 20 years ago. I pretend to be a maned wolf-shaped tree on the Internet. You've used stuff I've worked on.

Trans rights are human rights.

I'm @nrr1.618033989 on Signal.
One of the reasons why I put the bass down a long time ago is that I stopped having enough feeling in my left hand to be able to play many of the workout-type practice exercises without seriously injuring myself.

So, uh, here I am, 10 years later, with feeling finally (mostly) back.

Valérian has been on my feet nonstop since sunrise today.

With my having dumped my shitty practice amp in favor of just using a high-Z audio interface and an effects stack cobbled together in Pd to color the tone a little, I made the mistake of looking at MIDI pedalboard controllers.

Then, I made the mistake of looking at DIY MIDI pedalboard controllers.

I've been idly working off-and-on on a backup/archival system for Windows.

I think I finally chased down every API call for getting at everything on NTFS and ReFS volumes and hammered out an archive format for storing versioned snapshots of full NTFS and ReFS volumes with high fidelity.

Leica did a sort of Adventskalender this year on YouTube, and there's one detail that has me kind of spinning.

Where the fuck did they find a tape measure in Germany, let alone one with imperial measurements?

Laureline is padding around the house, chattering to anyone who will listen. (Importantly, without carrying a toy. That's different.)

She's funny. Her only goal in doing this is to get someone to say, "Hello!" Once that happens, she shuts up and runs right over to hang out for a bit.

The 1954 Michael Curtiz film White Christmas features Mary Wickes playing the role of Emma Allen, General Waverly's housekeeper at his, as she put it, "Tyrolean haunted house" in Vermont.

You may recognize her as Sister Mary Lazarus from the 1992 Emile Ardolino film Sister Act.

Oh, huh. How did I not know that Sheldon Axler was at SFSU?

His "Linear Algebra Done Right" was a good adjunct to Friedberg/Insel/Spence when a little more exposition on a topic would have been nice.

The cassgender urge to typeset your math notes from this past quarter and pull out your favorite vector art program to draw figures.

The genderfucked urge to do precisely none of that and instead look at really nice mechanical pencils and lead holders all day.

Terry Gilliam's 1985 film Brazil is a Christmas movie.

It's also free to watch on YouTube right now, albeit with ads, which honestly enhances the dystopian effect.

"Then, uh, what programming language do you use?"

"Ada mostly. C or assembly from time to time. Possibly also Smalltalk."

While I'm here: Paul Verhoeven's 1987 film RoboCop is a Christmas movie.
It wouldn't be entirely out of the question to interpret RoboCop as a western through the lens of Reagan-era austerity policy (and the Cold War-era containment policy that largely preceded it).

We even see the culmination of Nancy Reagan's life work through the course of the series.

Man, if there's anything I'm happy about having (from my vantage point at least) changed in information security, it's that social engineering is considered serious.

20 years ago, it was kinda laughed at, and I feel a little like it's bitten us in the ass.

I really should have named him Commander Shepard so I could crack the joke that I am his favorite place on the Citadel.

If you don't hear a praise break in the special stage soundtrack from Sonic 2, I don't know what to tell you.

I spent some of today putting together a computation expression in F# that lets me more or less write shell scripts there, in much the same manner as Haskell's Data.Conduit and friends.

I wrote another CE a while back for pipelines in PowerShell RunSpaces that I intend to bolt onto it.

My manifestation of 積ん読 is an album dedicated to covers of books I take photos of as I wander the stacks at whatever library.

"Oh, that looks interesting."

I sometimes wind up reading these! Hao's "Empire of AI" and Mollick's "Co-Intelligence" ended up this way.

Usually, it's Laureline who engages in sock crimes, but sometimes, Valérian sees fit to partake too, complete with singing the song of victory as he walks toward me.

There's a strange sort of irony in not having a love for tech anymore but having a draw to going back to running Plan 9.

This is the face of a boy who apparently does not want to be fed. I wouldn't mind giving him dinner, but his lying here is making it difficult.
