I’m updating my public SSH key; it’s long overdue to step out of the dark ages and move to ED25519.

My new key:

ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILDDULC1LD04Hss//MwUXumtJE0YiH1IrioRDly/jack

And yes, I worked very hard for those last five letters.

Below is a PGP signed message attesting to this change, including an identifying comment.

Keys for validation can be found on https://keybase.io/jackkingsman, retrieved via the fingerprint in the footer of any email I’ve sent you from a personal address, or retrieved yourself from the key with fingerprint:

I had too much time on my hands after work today and yesterday, so I made this silly site to celebrate my new shromps.

There’s nothing more to it, except that the shrimp dances faster each time you tap/click it.

skrimp. lol.

And the tetrapods and gabions look great, even if the round jar makes the cube looks like it’s melting haha. Yay shrimp!

I’m starting a new shrimp tank soon and I want to fill it with hollow tetrapods, commonly used for reenforcing shorelines. Their stable, interlocking shape combined with oblique surfaces for dispersing wave energy is idea. I just think they look cool, and think a carpet of them in a shrimp tank is both very aquatic (I see these all over shorelines I love).

I was pleased with my last post on getting TinyLibrary up and running on an ESP32 (and WOOOO got a PR accepted to the ESP-IDF codebase for the standard ESP32 firmware for DHCP option 114), but really wanted something with some more RF and speed oomph. I worked on an off for a while to get a captive portal + DNS + DHCP working on Ubuntu 24 on a RasPi Zero 2W but kept getting blocked by random issues. I finally decided to abandon my NetworkManager approach (turns out the dnsmasq-base plugin that it uses won’t read my DHCP configs even when they’re in the right place >.>) and finally went with the tried and tested combo of hostapd and full-scale dnsmasq and things went real smooth.

I’ve been on a big ebook kick lately (currently rereading the first scifi I ever consumed as a little kid, Contact by Carl Sagan). The concept of written words that have been a major part of my development (or recreation) being subject to the same resilience, shareability, and indexing as other digital goods delights me, so I’ve spent quite a bit of time and effort to get every book I’ve ever read (and some I haven’t read yet) into a well-tagged digital library that’s coming up on 800 books.

Last week, I implanted a SmartMX3 P71D321 secure element chip in an ultra-thin, biosafe-polymer-enclosed form factor as provided by the Dangerous Things flexSecure implant in my left arm. This microprocessor + radio provides onboard compute and a 13.56Mhz NFC radio, with the chip accepting 200kB worth of Java Card applets (extremely feature-restrictive/resource-minimal Java). While this technology is not new (Java Card SmartCards have been around since the late 90’s), this body-safe form factor is impressive even when compared with newer implantable NFC chips thanks to Amal Grafstra’s research into biocompatible polymer-encased planar antenna technology.

This weekend I implanted an xSIID, an implant that is essentially a copy of my first xNT implanted chip, except that this one lights up when you scan it. I am now not just a cyborg, but a disco cyborg 😎

Implant was very smooth; you can see in the mid-implant photo all the topography I charted to keep track of vasculature and tendon boundaries. The sweet spot was VERY tight; I had about +/2mm tolerance on where I needed it to land, but preliminary healing looks like I nailed the placement spot on.

What an awesome review of a side project I’ve been really passionate about. And he couldn’t have described the site better.

Super, super proud of seeing this in print.
