Ask HN: How much traffic do you serve and with which database engine? (ycombinator.com)
It's common to see here that Postgres hosted in RDS can handle 99% of workloads up to millions of users. I'm building an IoT app with a plan to ingest the IoT traffic into dynamo partitioned on user id (I'm quite familiar with the tradeoffs) and everything else be in Postgres. A few services but not microservice (basically: core service, identity service, IoT data service, notification service).

The Miserable State of Modems and Mobile Network Operators (golioth.io)
Golioth recently received a number of customer reports regarding connectivity issues on a specific vendor’s cellular chipset series. We immediately contacted the vendor and began working towards reproducing and isolating the behavior. What ensued was a lengthy investigation that ultimately revealed some unexpected and highly undesirable behavior. This is a story of the complexities of cellular connectivity, the perils of closed ecosystems, and how to debug what you cannot see.

Just barely fitting a full Wi-Fi stack on the nRF9151 (danielmangum.com)
In my last post on the Nordic Semiconductor Thingy:91 X IoT prototyping platform, I outlined the features and architecture of the device. The combination of wireless protocols on the Thingy:91 X (Bluetooth LE, LTE-M, Wi-Fi) make it a compelling foundation for a wide variety of applications. However, there are a few intricacies to the protocol support.

NAT Is the Enemy of Low Power Devices (golioth.io)
If you have ever tried communicating with a device on a private network, you may have encountered Network Address Translation (NAT). Fundamentally, when one device needs to send data to another device, it needs to know how to address it.
