**Fooling Go's X.509 Certificate Verification** New post on why verifying X.509 certificates in Go sometimes fails with seemingly identical CA certificates, and why different behavior in tools like OpenSSL further complicates the matter. danielmangum.com/posts/foolin...

Anyone working on agentskills.io? How are you distributing? Copy-pasta or some kind of marketplace?

TL;DR: Empathy for what customers are going through with their own builds Building hardware gets you into the nitty gritty details of building IoT products, including some of the challenges our customers run into with our services. blog.golioth.io/why-build-ha...

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...

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-...

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

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

#hugops to the Cloudflare folks today. 🧡

Knock knock! Who's there? A new #ZephyrRTOS release! 🪁 As always, it is packed with lots of new features and improvements so here's for your video tour :) youtu.be/xBVDxpsSqZQ #embedded #iot #opensource

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!

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-...

I whipped up a case for the @officialarduino.bsky.social Uno Q. * MakerWorld: bit.ly/43BpU3G * Printables: bit.ly/4qBBoho * Thingiverse: bit.ly/3Jz6uFU What's running *on* the Uno Q? Stay tuned...👀 #IoT #maker #devboard #Golioth #Arduino #3DPrinting #OpenSource #ArduinoUnoQ

@golioth.io ❤️ @officialarduino.bsky.social My UNO Q board arrived yesterday and it took only a few minutes to get up and running with an application that communicated with Golioth over Wi-Fi. I can’t think of a better development kit to demonstrate the flexibility of the Golioth platform!

Today we are launching support for device signed URLs on @golioth.io! Almost everyone uses signed URLs on a daily basis to access private content on CDNs, but they can also be useful in the context of complex multi-protocol embedded devices. Read more: blog.golioth.io/signed-urls-...

Awesome Bluetooth board that can be controlled from anywhere via @golioth.io! Hardware and firmware courtesy of @chrisgammell.bsky.social and @szczys.bsky.social — perfect little digital signage for the office.

We just moved #Bluetooth support on @golioth.io to open beta! That means anyone with a Golioth account can now use device management, data routing, and application services with BLE devices. Check out our new Golioth Connectivity documentation to get started! docs.golioth.io/connectivity...

Anyone tackling product explainer videos with AI?

@officialarduino.bsky.social has announced an update to its Zephyr RTOS-based Arduino cores, released following Arm's decision to shutter the Mbed OS project — and while they're still in beta, the new release adds some previously-missing functionality and a range of bug fixes.

We're excited to make another step in our beta program for Arduino cores based on Zepyhr with the release of v0.3.2. See what's new in this update: blog.arduino.cc/2025/08/06/u...

Playing around with @canonicalltd.bsky.social Multipass this weekend, should have tried it sooner. Great devexp, especially on macOS.

Kids these days don't appreciate how hard it used to be to center a div.

something new from @golioth.io tomorrow 👀

Already starting to see @kiro.dev-inspired projects. Ex. github.com/Pimzino/clau... AWS definitely struck a chord with devs.

Another Hardware Happy Hour is coming up on July 29th in Raleigh/Durham/Chapel Hill (and actually Cary for this one). Please share it with anyone you know in the area who might be interested: lu.ma/s3jyicee

I find the idea of a mostly 3D motor intellectually intriguing but not super practical. However, it might be interesting to integrate it with something like a cycloidal drive (which YouTube loves these days.) youtu.be/OZarwftUh8w?...

**How AI on Microcontrollers Actually Works: Registering Operators** Much attention is (rightfully) given to model optimization when attempting to perform inference on the most constrained edge devices. Optimizing the inference runtime can sometimes be overlooked. danielmangum.com/posts/ai-mic...

Marjorie Taylor Greene doesn't want you to know the name of her opponent but will try every desperate attempt to save her seat. My name is Shawn Harris. I am a Democrat, husband, father, Retired Brigadier General, farmer, and I'm running against MTG. Can you spread the word?

tinymcp works by translating MCP client JSON-RPC tool calls into @golioth.io LightDB State and device RPC API calls. Try it out with the blink example on a @nordicsemi.com nRF9160. github.com/golioth/tiny...

tinymcp: Unlocking the Physical World for LLMs with MCP and Microcontrollers Today we are excited to launch the tinymcp project, a Model Context Protocol server and framework that enables LLMs to remotely interact with even the most constrained embedded devices. blog.golioth.io/tinymcp-unlo...

It was a big week for our friends @memfault.com and @nordicsemi.com! On a slightly smaller note, we also introduced a new feature in our @golioth.io Pipelines Memfault data destination to support user-managed device serial numbers. It only requires changing one line of YAML in existing Pipelines.

**THE ABSOLUTE SIMPLEST WAY TO UPLOAD IMAGES FROM A MICROCONTROLLER TO THE CLOUD** We are partnering with the @openmv.io team to add native @golioth.io support for their camera modules. I just received the new AE3 and was able to get image upload to an S3 bucket working in under 5 minutes!

Golioth has come up with a new trick for users of its platform: interacting with their embedded devices through an SSH-like connection — "with limitations," the company admits.

Last week I demoed @golioth.io to a customer using a device that was running firmware I had never seen before...

New library for Zephyr libmpix that efficiently works with image data. 🪁📚🖼️ libmpix.org

Yesterday @golioth.io suffered a partial outage, impacting customer devices leveraging our stream and OTA services. We take the availability of our services very seriously, and yesterday we fell short of our standard. Our incident report provides more information. blog.golioth.io/june-12th-20...

AWS announced that they are ending support for three IoT services, becoming the latest cloud provider to struggle with enabling connected device products. These heterogeneous systems require a robust integration layer, which is the approach we have taken in building @golioth.io.

We just launched Pipeline Recommendations on @golioth.io! Pipeline Recommendations analyze streaming metadata to automatically generate new pipelines for routing device data. This ensures that you aren’t missing out on data, and works as a powerful discovery tool when on-boarding legacy devices.

Can we add cellular support to a popular GPS watch? We just wrapped up our quarterly @golioth.io hack day, and I spent mine adding cellular to a Garmin watch using the @nordicsemi.com nRF52840 and nRF9160. In just a few hours, I was able to livestream my location data to any cloud service.

DeepSeek-R1-0528 has once again set the benchmark for open weights models. Using @basetenco.bsky.social and @golioth.io Pipelines, we can easily swap out a proprietary OpenAI model for R1 by changing just a few lines of YAML. I grabbed an ESP32-S3 based device to quickly try it out!

Need to know what components are inside a device but don't want to crack it open? Let's take a look at how we can use the FCC ID database to determine that my Garmin Forerunner 55 GPS watch is using a @nordicsemi.com nRF52832 MCU for BLE support.

Today I tried four berry pie for the first time with my wife's Midwest family. Cherry is considered a berry and I'm shook.

Yesterday @anthropic.com released Claude 4 and a number of new API capabilities. The Files API allows for uploading images, then referencing them by ID in prompts. I decided to grab my @openmv.io Cam RT1062 and see how quickly I could start using Claude 4 with a microcontroller via @golioth.io.

You can check out the @golioth.io Location service here: docs.golioth.io/application-...

With cellular, Wi-Fi, and BLE support, the @nordicsemi.com Thingy:91 X is the perfect prototyping platform for testing @golioth.io's network-based positioning service. I took it out for a run on Duke University's campus to see just how accurate Golioth Location is... spoiler: no GNSS, no problem!

I'm stumped. I thought it would be "easy" to run a Bluetooth script in a Docker container. Tried every suggestion online, even resorted to vibe coding. No luck on a Raspberry Pi 4 or Ubuntu laptop. Anyone else figure this out?

I've got a new office / studio and this is the first Friday I've had an opportunity to record some new content. Running through some examples of mixing local inference on the Qualcomm RB3 Gen 2 Vision Dev Kit with cloud inference via @golioth.io's AI platform integrations!
