Strangler Figs is a nightmare that lives on other tropical trees, stealing their soil nutrients, water, and even sunlight through a canopy of dense leaves and roots that twist around the host plant. Eventually, the fig's roots can completely encase the host, strangling its trunk and cutting off nutrient flow until it dies and rots away leaving just the hollow fig behind.

In this post, You will understand how to collect values from an Arduino with a connected Raspberry PI over a serial port. This can be useful if you want collect sensor values over a period of time and store them on a timeseries database or trigger an alert either from the Raspberry PI (email notification or telegram alert) or from the Arduino (like fire alerting systems). Let's dive in!

Service is a resource you create to make a single, constant point of entry to a group of pods providing the same service. Each service has an IP address and port that never change while the service exists. Clients can open connections to that IP and port, and those connections are then routed to one of the pods backing that service. This way, clients of a service don’t need to know the location of individual pods providing the service, allowing those pods to be moved around the cluster at any time.

Apache Cassandra is a free and open-source, distributed, NoSQL database management system designed to handle large amounts of data across many servers, providing high availability with no single point of failure. Cassandra offers robust support for clusters spanning multiple datacenters, with asynchronous masterless replication allowing low latency operations for all clients.
You can do that in Django using a middleware. The middleware needs to generate a unique request id (e.g. using UUID) and associate that id with the request.
