For all the hate that Java gets, this *not rant* is to appreciate the Spring Boot/Cloud & Netty for without them I would not be half as productive as I am at my job.

Just to highlight a few of these life savers:
- Spring security: many features but I will just mention robust authorization out of the box
- Netflix Feign & Hystrix: easy circuit breaking & fallback pattern.
- Spring Data: consistent data access patterns & out of the box functionality regardless of the data source: eg relational & document dbs, redis etc with managed offerings integrations as well. The abstraction here is something to marvel at.
- Spring Boot Actuator: Out of the box health checks that check all integrations: Db, Redis, Mail,Disk, RabbitMQ etc which are crucial for Kubernetes readiness/liveness health checks.
- Spring Cloud Stream: Another abstraction for the messaging layer that decouples application logic from the binder ie could be kafka, rabbitmq etc
- SpringFox Swagger - Fantastic swagger documentation integration that allows always up to date API docs via annotations that can be converted to a swagger.yml if need be.
- Last but not least - Netty: Implementing secure non-blocking network applications is not trivial. This framework has made it easier for us to implement a protocol server on top of UDP using Java & all the support that comes with Spring.

For these & many more am grateful for Java & the big big community of devs that love & support it.

Kafka lead after a perf test - we have amazing performance, processing 43 records a second😄
Me - WTF!!!! 🤬

Why are some people incapable of reading documentation? THE "DUPLICATE RECORDS" IN OUR KAFKA TOPIC ARE BECAUSE ITS AN EVENT STREAM AND NOT A DATABASE. THIS IS LITERALLY ON THE FIRST PAGE OF THE GUIDE YOU ABSOLUTE MORONS.

Today our customer tried to change the log dir of Kafka. Too bad he did not change the intended log4j.log, instead he changed the log.dir where kafka writes his data.

He basically tried to change the tires at 180km/h at the Autobahn. Only god knows how he managed to get the tires off. After that he slided a kilometer on his rims and wondered why the car wouldn't drive anymore.

Consumers fucked, Topics fucked and Producers fucked
