the show must go on.

new blog post tomorrow.

read the first 100 pages of the three-body problem this afternoon, and I think this may be the most brutal burn I have ever encountered.

**Determining Current Arm Cortex-M Security State with GDB** A short post on how comparing the current stack pointer register to the main and process stack pointer secure and non-secure variants can be used to determine the security state of Armv8-M processors. danielmangum.com/posts/arm-co...

The holidays are a great time to do some personal development (hacking) projects. Dylan and @szczys.bsky.social rebuilt a meme machine on top of @adafruit.com's MagTag board Read more about the project and view the full video here: blog.golioth.io/a-physical-m...

let’s build something great this week!

what are we hacking on this weekend?

thank you, GKE, for these wonderfully helpful recommendations for the same workload.

fridays are for demos!

New @golioth.io Firmware SDK release is now available! v0.22.0 includes certificate rotation, enhanced logging flexibility, cleaner separation between OTA download and firmware update, and much more. Check out the blog post for more details! blog.golioth.io/golioth-firm...

We just made it possible to use any logs service with embedded devices... without changing any firmware. Introducing @golioth.io Device Logs Anywhere, which leverages the flexibility of Pipelines to transform & route your device logs to platforms of your choosing. blog.golioth.io/device-logs-...

Excited for hosted PKI integrations to land on @golioth.io today! We're eliminating the complexity in establishing robust PKI for your fleet, and making it easy to build automatic certificate rotation into your firmware, regardless of the underlying infrastructure. blog.golioth.io/introducing-...

it’s race day.

last race of the year tomorrow, and at the very least I’m guaranteed to set a new personal best for lowest marathon temp.

TIL that @github.com supports rendering CAD files in the browser. Featuring the new Pebble Index 01 from @ericmigi.com and team.

thankful for compelling bugs.

time to make some ornaments.

Hackday at @golioth.io and @szczys.bsky.social is spreading propaganda that I endorse.

I have always been extremely annoyed with pull-up resistors being described as "pulling an input high" when the input reading high is not due to the presence of the resistor.

fridays are for demos!

lol.

I really want to start livestreaming on regular cadence again.

🍩 Thanksgiving is the best holiday if you’re testing a food inspection hardware project 🍩 @sparkfun.bsky.social

it's not a friday afternoon until the oscilloscope comes out.

fun discovery in the crawl space this afternoon.

it’s race day.

fridays are for demos!

come train in North Carolina, where you can run in a humid 80 degrees one day and a frigid 30 degrees the next.

This weekend I reached 3,000 miles running in 2025 after initially accomplishing the goal in 2023. I wrote a few words about the unique challenge of doing a difficult thing a second time, and why you have to make hard things possible before you can make them normal. danielmangum.com/posts/possib...

ICYMI I wrote about how FPGAs are configured and why that can lead to some interesting SPI routing on Lattice iCE40 development boards.

**Interesting SPI Routing with iCE40 FPGAs** I wrote about iCE40 FPGAs, and why the way an FPGA is configured can lead to interesting board design decisions. @mith.ro's Fomu is a useful study due to eschewing a USB-Serial chip for accessing the FPGA and SPI flash. danielmangum.com/posts/spi-ro...

new blog post tomorrow.

go for walks.

I think @golioth.io may be the first custom Brick in @officialarduino.bsky.social App Lab 👀 We make use of both the BLE and Wi-Fi connectivity on the UNO Q to proxy data for BLE peripherals, stream data from attached sensors, and perform network-based positioning with Golioth Location!

compute is distributed, more and more

We just released v0.2.0 of signy, our signed URLs library for embedded devices! This release includes support for ESP-IDF, which enables some new interesting use cases, such as leveraging the esp_http_ota component for OTA firmware updates from @golioth.io. blog.golioth.io/signed-urls-...

@golioth.io ⚡️ @edgeimpulse.com ⚡️ @nordicsemi.com Working on a fun project with @szczys.bsky.social this weekend combining Edge Impulse gesture recognition models with Golioth Bluetooth connectivity, running on an nRF52840 connected to the Tikk board (by @chrisgammell.bsky.social) for LEDs and IMU!
