👁️🗨️ Grayskull: A tiny, dependency-free computer vision library in C for embedded systems, drones, and robotics.
｢ Grayskull is a minimalist, dependency-free computer vision library designed for microcontrollers and other resource-constrained devices. It focuses on grayscale images and provides modern, practical algorithms that fit in a few kilobytes of code. Single-header design, integer-based operations, pure C99 ｣
⚡ Porting Lean to the ESP32-C3 RISC-V microcontroller
｢ Lean is a dependently typed pure functional programming language and a proof assistant, though in this article I will mostly be using it just as a programming language. Its compiler can either emit LLVM IR or C code ｣

The most thought provoking article I have read this week:
A Norwegian bus company wants to know if their buses could be abused by China in the case of war.
So they drive two buses deep into a limestone mine to isolate them from the internet and forensically investigate how they work.
In the mine, investigators discover a Chinese kill switch which could destroy all Chinese buses.
In Denmark, that is 57 percent of the bus fleet.

Time and time again you have asked me if I could please give a brief video interview to a gentleman wearing a cravat about the work we do @opencage with IoT companies.
Well, my friends, I'll admit I thought about holding this back for the VIPs on my OF feed, but, in the end, where will greed get me? Is it not better to share?
In this spirit, here is the interview from late September at the Things Conference in Amsterdam

👻 Manufacturer issues remote kill command to disable smart vacuum after engineer blocks it from collecting data — user revives it with custom hardware and Python scripts to run offline | Tom's Hardware
Got the email that Belkin are killing off the WeMo cloud & app for their smartplugs.
Local control still works fine though. Easily integrated into HomeAssistant.
Lots of cheap WeMo bits on eBay if you want a local-first smarthome.

Ein Ingenieur entdeckte, dass sein smarter #Staubsauger heimlich #Telemetriedaten an den Hersteller ohne Einwilligung sendete.
Als er den Datenfluss blockierte, wurde das Gerät per Fernbefehl blockiert.
Nach Analyse und Reverse Engineering konnte er das Gerät mit #Python-Skripten und einem #RaspberryPi wiederbeleben. Der Fall zeigt, wie sensibel #IoT-Geräte mit Nutzerfreiheit und #Datenschutz umgehen.
You never *really* own smart devices.
This is an excellent example of how the #SurveillanceEconomy works with #IoT #smartdevices
The manufacturer has built in the sale of customer data to their business model. So if you block the transmission of that data back to them then they brick your device.
Despite you never consenting to having that data harvested in the first place!
And this kind of #metadata is used to triangulate your #data in anonymised data batches 😞
