Tiny Code Reader: a $7 QR code sensor (excamera.substack.com)
typically on these cameras the lens is mounted and focused by a screw thread. there is not usually an 'infinity stop' because the mount is very simple, so i would expect the lens may be mechanically positioned outside the useful focus range. a 110 degree FoV is a very wide lens, so the useful screw ...

Tiny Code Reader: a $7 QR code sensor
Tiny Code Reader (TCR) caught my eye when it came out in 2023. It’s a very appealing idea: a self-contained seeing module that just decodes any QR code it sees. I immediately imagined applications in desktop manufacturing, a subject very dear to my heart.
You can buy it from Adafruit, Sparkfun, and ...

Exposing the Unseen: Mapping MCP Servers Across the Internet
Knostic’s research team conducted a systematic study to locate exposed MCP servers on the internet. Leveraging Shodan and custom Python tools, we fingerprinted and mapped production MCP servers. All servers we discovered were insecure and revealed their capabilities to anyone asking.
In this series ...

Exposed MCP servers across the internet (knostic.ai)
Sure, but I was expecting more details on what was available. At least some analysis (perhaps using embeddings) on common function names, types, etc. What are people exposing? Is there overlap? What % of the open servers looked the same (indicating a common example / tutorial deployment)? What's the...

Metaflow: Build, Manage and Deploy AI/ML Systems (github.com/netflix)
I've used Metaflow for the past 4 years or so on different ML teams. It's really great!
Straightforward for data/ML scientists to pick up, familiar python class API for defining DAGs, and simplifies scaling out parallel jobs on AWS Batch (or k8s). The UI is pretty nice. Been happy to see the active ...

Why I'm No Longer Talking to Architects About Microservices
It happened again last week. I was at an architecture review meeting when a fellow architect eagerly started another debate about *microservices*.

MCP is the coming of Web 2.0 2.0 (anildash.com)
The thing that a lot of people miss with MCP is that it's the right fit for enterprise software. LLMs, being universal translators, are the ideal glue between many disconnected systems that are extremely hard to connect without some fuzzy layer in between. And so that's why you see so much of the B2...

The biggest lesson that can be read from 70 years of AI research is that general methods that leverage
