Effective Java: try v/s try with resources

Reading Time: 3 minutes It’s not uncommon to acquire resources while developing and forgetting to close them. For example, InputStream is a resource that would be explicitly needed to be closed and hence can be often overlooked.  To effectively work with our resources it is important that we return the resources as soon as we are done using them else they may lead to performance consequences. One of the Continue Reading

Java: back to basics.

Constructors vs Static factory methods

Reading Time: 4 minutes Instantiating the object of the class isn’t really the most difficult job in the world. Rather I’d say its one of the most basic things about any programming language. As you must’ve guessed it, I’m referring to a constructor. A constructor is a method whose name is the same as that of the class its part of, and which returns the instance of the class.

Spring WebFlux: Error handling in Reactive Streams

Reading Time: 3 minutes Error handling is one of the ways we ensure we are gracefully handling our failures. While working with streams of data, the Reactive Library Reactor provides us with multiple ways of dealing with situations where we need to handle our errors. In this blog, I wish to discuss a few of them with you.

In Deep: The bill of materials in Maven

Reading Time: 3 minutes Lately while working with Spring WebFlux, I came across this really helpful concept of the bill of materials also known as BOM, a concept not really limited to Spring at all. BOM is one of the few ways Spring helps us forget about issues related to transitive dependencies and focus solely on our project requirements. So when we generally create a large scale project with Continue Reading

Lifetime in Rust – Part 1

Reading Time: 4 minutes Rust can be a tricky language to work with and one of the prime reasons for that is the way it manages its memory. In my previous blogs, Ownership, and References I discussed how Rust works its memory management and how it manages to refer to a variable without actually taking the ownership of the variable. Now, let’s take a step further. What happens when Continue Reading

Working with Project Reactor: Reactive Streams

Reading Time: 4 minutes .The words “Reactive” and “Streams” often go hand in hand. The streams API of Java 8 is a great tool for making your projects Reactive. But that’s not the only stream you can have. In this blog, I’d like to talk about this awesome project called Project Reactor.

Options in Rust

Reading Time: 3 minutes To be or not to be, that’s an Option! Many programming languages have the feature where they intend to depict a Null. Null as a value conveys that either it is currently invalid or currently unavailable. Such a state is important in a programming language. It’s a perfectly valid use case to convey the validity of a value. But still, the inventor of Null, Sir Continue Reading

Rust – References

Reading Time: 3 minutes In my previous blog, we discussed how Rust performs memory management. Interesting as it is, the concept of ownership does come up with a few obstacles when it comes to programming. For instance, if we use a variable as a parameter to another function, Rust doesn’t allow us to access the same variable in that scope anymore. For more details as to why that happens, Continue Reading

RUST – Ownership

Reading Time: 5 minutes One of the very distinctive features that make Rust stand out among the other languages is the way it does memory management. Memory management in C happens by either declaring a variable or by allocating a chunk of space at runtime. The same then can be freed using explicit function calls. So basically the control resides with the developer which may result in error-prone code. Continue Reading

Distributed Transactions and Saga Patterns

Reading Time: 6 minutes In a Knolx session organized by Knoldus, we discussed the idea of following Saga Patterns. For that to be more accessible, I’d like to share the session with the help of this blog. Service-oriented architecture has given us enough advantages to be a predominant architecture in our Industry, but it can’t be all sunshine and rainbows. There are use cases where monoliths are not only Continue Reading

Apache Solr : Did someone say search engine?

Reading Time: 4 minutes Apache Solr Solr is the popular, blazing-fast, open source enterprise search platform. It is one of the easiest ways of developing sophisticated, high-performance search applications. Based on another  Apache product Lucene, Solr provides developers with capabilities such as advanced full-text search capabilities, scalability, easy monitoring and much more. This blog intends to get you started with Solr and helps you interact with a Solr server.

Unit Testing – The good, bad & ugly

Reading Time: 4 minutes Unit testing is common to all the codes that we write. We all do it, so it’s important to understand the most “looked forward” (sarcasm) aspect of development. However overlooked and underestimated, Unit Testing forms the most important part of any development cycle and hence it’s worth delving into. So let’s begin. So the big question at hand is, what is Unit Testing? “A unit test Continue Reading
