ThingsBoard Microservices Installation Update Problem
Until recently I was still using TB v3.2.1, now I've set about updating the installation to the latest version. I proceeded as described at https://github.com/thingsboard/thingsboard/tree/master/docker:

Looking to implement a real time tracking feature in my Django project and I dunno where to begin
You might find something more attuned to that use case to be more helpful out of the box (like thingsboard.io) but if you're committed to django, set up an API endpoint to receive json updates ('events') sent from the arduino.
- Sites to download source code from? (Leaked or not)
- Suitability of GCP pubsub or Firebase for IoT devices instead of AWS IoT Core?

Best Four IoT Platforms
Introduction:As a 100% open source IoT platform that can be hosted as a SaaS or PaaS solution, Thingsboard can provide device management, data collection, processing and visualization for your IoT project. The standard protocols that provide device connectivity such as MQTT, CoAP, and HTTP are all available on ThingsBoard. In addition, it supports cloud and local deployment and provides more than 30 customizable components that allow you to build end-user custom dashboards for most IoT cases.

Zelensky: “Ukraine has a lot to offer the world, products and services created by Ukrainians. Ukrainian companies – join. World – use. Tell your foreign friends about it. Spend with Ukraine to stand for Ukraine.“
The company I work for uses https://thingsboard.io and the team from Ukraine that built it are awesome and the company is still responding even though they are going through this hell of a war.

Restrictive Abstractions
This interface is a simplified version of real caching abstractions from Java technologies such as the ones from Spring or JCache (JSR-107). Both are part of quite complex solutions, having more generic types and different capabilities. Also, annotations would be preferred to using Cache directly in most Java applications.

CWE Top Most Dangerous Software Weaknesses
Mitre really lost a lot of respect with CVE-2016-1000027. Every few weeks a warning that any SpringBoot 2.x project has a CVSS 9.8, which causes all sorts of heartache for those of us bound to CVE remediation. Every blasted security tool reports this one. Spring reviewed and rejected, as did our very, very large organization. Comically, this has become the CVE we use to see how our tools allow us to white/black list entries.
Thank god Spring dropped this interface in the Framework 6.x / Boot 3.x release, and the end for non-commercial support is this year for the old stuff.

Help with GetMapping annotation
Referring to https://github.com/spring-projects/spring-framework/blob/main/spring-web/src/main/java/org/springframework/web/bind/annotation/GetMapping.java, the value could have got assigned to any of the other members like name, path, params, etc. Is there any logic involved that enables the single value passed to the GetMapping annotation to be assigned to the value member?

What's your most painful experience of debugging an issue that only reproduced in production?
This one. In short, JMS listeners stopped working randomly (of course only on Saturdays, and only under load), but at first we didn't know that and suspected the message broker at fault. We had quite extensive logging, but no observability on the broker. Can't remember all the details, but eventually we figured out it was the listener container, and I could reproduce it after debugging deeply into Spring code during a load test.

how does spring webflux interact with the java servlet api?
Simple: Spring WebFlux does not require Servlet, but can adapt to it. We essentially built our own reactive HTTP abstraction, without any Servlet dependencies. Then we made adapters that use said abstraction for (Reactor) Netty and Servlet. Note that we have specific adapters for Tomcat, Jetty, and Undertow, relying on non-blocking native APIs.
