Unit testing is an essential part of software development. Unit tests help to check the correctness of newly written logic as well as prevent a system from regression by testing old logic every time (preferably with every build). However, there are two different approaches (or schools) to writing unit tests: Classical (a.k.a Detroit) and Mockists (or London) schools of unit testing.

In my past life, I spent many hours researching, creating, explaining, and publishing portfolio architectures across a collection of application development, domain verticals, infrastructure solutions, and hybrid cloud domains. Most of these concentrated on the application layers and their usage of the infrastructure. Then, I transitioned into the cloud native observability space, and observability became the guiding light on my learning path.

January has been notable for the number of important announcements in AI. For me, two stand out: the US governments support for the Stargate Project, a giant data center costing $500 billion, with investments coming from Oracle, Softbank, and OpenAI ; and DeepSeeks release of its R1 reasoning model , trained at an estimated cost of roughly $5 milliona large number but roughly one-tenth what it cost OpenAI to train its o1 models.

In the not too distant past, software development was notorious for taking too long, costing too much, and having a high rate of cancellation. Companies spent months doing up-front analysis and design before a line of code was written. The entire solution was coded before being deemed ready to test. Users only got a glimpse of the software shortly before the go-live date.

Traditionally, logging has been unstructured and relies on plain text messages to file. This approach is not suitable for large-scale distributed systems emitting tons of events, and parsing unstructured logs is cumbersome for extracting any meaningful insights. Structured logging offers a solution to the above problem by capturing logs in a machine-readable format such as JSON, and it becomes easier to query and analyze log data in a system where logs are aggregated into centralized platforms l
