I work in embedded systems. Not that I'm good at it.

nickthenerd··on Is it time for a new Embedded Linux build system?
Doing this on target seems terrible. What an awful development experience.

The source site/paper won't load for me at this time, but if the device has a cellular modem in it for network connectivity, it will 100% be assigned an IPv4 address from the carrier. Unless this device is using an APN at the carrier level, or is using a SIM provider that provides some additional security.

nickthenerd··on Ask Wirecutter: Can you recommend a not-smart TV for me?
Yes. I was looking for this comment before saying the same. This is the biggest selling point of Sidewalk to appliance/product companies. All the usage data, ad data, analytics, even remote control of devices can now happen even if your devices are completely disconnected from your home WiFi. If your neighbor has an Amazon Echo... now its basically connected to the internet. Even if you don't have neighbors, there could be a LoRa gateway a mile away on a cell tower, and its now connected.

> de facto IoT MCU

Not at all, at least not professionally. Mostly mocked and avoided professionally. But prosumer and hobbyist, it’s probably the most popular. They are fun to prototype with and use around the house but I would never stake my business on them.

nickthenerd··on Securing name resolution in the IoT: DNS over CoAP
Technically Matter can run purely local, no external web requests (well there are some attestation and certs that are confirmed by the Controller). Then Matter devices use Endpoints and Clusters for control, device to device or Controller to device. Matter devices' Commissioning process is done in 2 ways - for Thread devices, they require the operational dataset of the Thread network, which is held by the Border Router, then the Border Router needs information about the Thread Device (Device ID, Discriminator, and PIN Code). This can be exchanged over BLE or NFC with the Controller (smartphone app like Homekit, Google Home, etc). If you have WiFi only devices then Commissioning is done via the Controller only. In both of these cases any DNS lookup would be done by the Controller.

nickthenerd··on Why trademark Open Source software
I think its important to understand what you are also getting into with a trademark. They mention:

    actively asserted and defended in order to have legal meaning.
This is a critical piece of owning a trademark. It must be defended which means that you have to issue cease and desist letters, normally engaging an attorney to do so, or else you risk losing your trademark altogether or it becoming genericized, i.e. 'Kleenex': https://en.wikipedia.org/wiki/Generic_trademark
