"Terminology for Constrained-Node Networks" (IETF Draft RFC 7228bis) has some useful classifications of devices on dimensions of RAM / flash, upgradability, isolation, secret shielding, available power, networking capabilities, bandwidth, and more. www.ietf.org/archive/id/d...

what a joy to think deeply and understand.

been a while since I used cloud run and I actually really like how they haven’t abstracted that functions are just containers they build for you. makes it pretty easy to move from code to container in the future.

new hardware day.

top two takeaways from my two week europe excursion: 1. The secure element / MCU TEE market is too fragmented. 2. London is a top 5 running city in the world, and Nuremberg is top 30.

writing your own presentation software so you can still do engineering while constantly forced to prepare slides.

decided to add another race to the calendar on short notice. if you're running the Victoria Park Half Marathon in London feel free to reach out!

new hardware day! @frame.work

fun demo with @golioth.io + @tailscale.com + @influxdb.com + @grafana.bsky.social to route embedded device sensor data from anywhere in the world to my local machine.

compliant mechanisms are incredible.

The Amp Hour is always good, but this episode with @chrisgammell.bsky.social and @ericmigi.com is truly excellent. They do a great job of articulating the challenges, trade-offs, and, ultimately, the joy of building consumer hardware products that you can call "done". Give it a listen!

good morning, orange site.

tonight I watched a norwegian man run up a hill at sub 6 min/mi pace... on skis. the olympics are incredible.

looks like we are doing the orange site this morning.

using solder to strip enamel from 28 AWG copper wire.

It's always kind of interesting to see people in very public influential leadership positions have extremely emotional reactions to competition and objectively minor critiques. Outside of it being textbook poor leadership, it also makes you wonder how they even make it through an average day.

happy nyc marathon registration day!

**Making Ferrite Core Inductors at Home** New post in which I walk through how to make inductors, and how the construction of an inductor impacts its attributes, particularly in the case of using a core material with high magnetic permeability. danielmangum.com/posts/making...

my grandmother somewhat regularly pops up on LinkedIn and drops a comment on one of my blog posts to the effect of “I understood none of this, but I love you very much”, and I for one think that’s pretty freaking awesome.

all fast runners I know are great at running fast. all very fast runners I know are great at running slow.

I am not surprised that this is troubling, but I am troubled that this is surprising.

1. mistakes were made on this joint 2. iPhone cameras are incredible these days

the xkcd “waiting for my code to compile” looks more like this at @golioth.io on a Friday evening.

the continuity checks will continue until morale improves.
