Lombok Is a Crutch — You’re Writing Java Wrong
- Lombok might be doing more harm than good by encouraging developers to ignore good design and lean on shortcuts.
- Java's verbosity is one of the main reasons for Lombok's popularity, as it reduces the ceremony of writing boilerplate code with annotations.
- However, Lombok does not address the root problem of writing excessive boilerplate-heavy classes in the first place.
- Lombok's @Data annotation, often used without much thought, can lead to the exposure of mutable internal state and violation of object-oriented principles.

Java Is Becoming the New COBOL — Legacy Without Innovation?
- Java, like COBOL, is being used out of necessity rather than passion as an increasing number of developers are choosing other languages that align with modern development styles.
- Java, though mature and trusted, is playing catch-up with other languages that are pushing boundaries in areas such as memory safety, simplicity, concurrency, and modern paradigms.
- Developers today prefer languages like Rust, Go, TypeScript, and Kotlin that are functional-first, async-native, lightweight, and cloud-optimized.
- The ecosystem of Java may stagnate further without fresh minds innovating, as the best developers are shifting towards other languages taught in university curriculums and used by startups.

How to Test CompletableFuture.runAsync()
- To test CompletableFuture.runAsync() method, one can use Awaitility library.
- The traditional approach of using Thread.sleep(...) to wait for asynchronous processing is inefficient.
- By adding the Awaitility library as a dependency, test assertions can be wrapped with the await method.
- The Awaitility library repeatedly evaluates the assertions until they are successful, ensuring completion of asynchronous processing before verification.

Why You Should Stop Using Goroutines in Production Services
- Uncontrolled use of goroutines in production-grade systems can lead to unpredictable behavior, memory leaks, data races, and difficult-to-reproduce bugs.
- Each goroutine starts with a small stack, but as they grow, memory usage increases, potentially leading to performance issues.
- The unbounded use of goroutines without error handling, cancellation, retries, or observability can bring down the service.
- Developers should reconsider their use of goroutines in production services and adopt better practices to ensure system stability and maintainability.

Why We Ditched Drizzle & Knex in favor of Kysely's Querybuilder
- ORMs like Knex and Drizzle, while promising rapid development, can obscure SQL and create bottlenecks with growing complexity.
- Kysely offers a balance of control, maintainability, and end-to-end type safety for database interactions.
- ORMs hide real database interactions, making query optimization and troubleshooting difficult in complex apps.
- Strict patterns in ORMs can limit customization and lead to convoluted code when deviating from standard use cases.
- For complex queries, ORM syntax becomes cumbersome and error-prone, especially in production-grade systems.
- Type safety in query builders is crucial for preventing errors at compile time, like incorrect table references or typos.
- Kysely aims for strict type safety, unlike Drizzle and Knex, ensuring correct query construction and avoiding runtime failures.
- Kysely's fully type-safe implementation enhances query safety and maintainability compared to Knex and Drizzle.
- Kysely's SQL-like query construction, combined with strict typing, offers a clear advantage in developing scalable applications.
- Embracing type-safe query building with Kysely provides control over database interactions and robust type validation for high-performance applications.

I Thought I Was Ready for a Backend Job, but Reality Disagreed
- When aspiring to be a Backend Developer, it is important to learn multiple programming languages and frameworks, not just rely on JavaScript.
- JavaScript for backend development is not as popular in the job market, especially for beginners, and it is more of a 'nice to have' skill.
- Recommended languages and frameworks for backend development include PHP (Laravel), Java (Spring Boot), Python (Django), and Go (popular, but framework name unknown).
- In addition to language and framework knowledge, it is crucial to learn SQL queries, version control with Git, and other tools like Docker, AWS, GCP, and CI/CD.

This Is Tuple Context Pattern
- The article introduces the "Tuple Context" pattern for React and Preact developers using the Context API feature.
- The pattern aims to enhance the robustness and usability of Context usage in large-scale applications.
- It simplifies managing business data by structuring the Context as a fixed-size array, separating reactive variables and mutation functions.
- By structuring the data in this way, the pattern makes it easier to access and update Context values within components.
- The Tuple Context pattern involves creating separate arrays for constants/reactive variables and functions that mutate the Context state.
- It allows developers to extract and use the parameters independently based on their requirements.
- For TypeScript users, defining data types is crucial for better code organization and readability when implementing the Tuple Context pattern.
- The article explains how to define interfaces and types for the Context state and dispatchers to ensure type safety.
- Overall, the Tuple Context pattern offers a structured approach to Context management, improving maintainability and code clarity.
- Developers are encouraged to try out this pattern and share feedback on its usability and effectiveness in their projects.
