The Difference Between @Bean and @Component and When to Use What? This is the most common question that new as well as experienced Spring users get confused about. There are literally hundreds of questions on this Stackoverflow. This article will clear all the confusion. Similarities between @Bean and @Autowired @Bean @Bean is an annotation based configuration and hence is used in @Configuration based class. This is an explicit way of defining a bean and is also used on the methods defined in configuration class.

Scala: Tail Recursion

📅 Mar 20, 2017 · ☕ 3 min read · ✍️ Dinesh

Tail recursion is a basic but important concept in Functional programming. Recursive functions has always been a pain point for me. I would be eliminated out of several interview rounds if interviewers places emphasis on recursion. In Java world thankfully, most people I know hate recursion because when nesting goes too deep, it impacts the performance if the nested recursion is more than 100 levels deep. Unfortunately(Fortunately), functional programming languages like Scala and Haskell have solved this concept with the term Tail Recursion.

How to set up Apache Storm on mac using brew

📅 Dec 26, 2015 · ☕ 3 min read · ✍️ Dinesh

I am learning about Apache Storm and the guide had long and winding instructions on how to install Apache Storm. I installed the single node using brew and it was a breeze. I did not had to spend time figuring out out if I was installing latest version. Pre-requisites: Make sure that you have ‘HomeBrew‘ installed. One reason that I prefer ‘brew’ is that I do not have to remember where things are installed and brew manages and fixes any updates that have been introduced.
