Reader-writer locks are one of the most intriguing topics in Golang. Golang web app development requires extensive use of goroutines and channels, which support concurrency. And this is where locks, or as we will learn reader-writer locks come in handy.  What is the Concept of Locks in Golang? The notion of locks is not only restricted to Golang, but it can be applied in a plethora of  ing languages. Locks, which prevent access to sensitive data, may cause additional overheads in complex applications. Then it has to be optimized by developers. Reader-writer locks are one of the most popular techniques to optimize it. Developers who are new to the concept of locks use Golang to comprehend the idea. This is because Golang has a great reader-writer lock implementation and concurrency support.  What is the Requirement of Reader-Writer Locks? As long as no one modifies the shared data while it is being read, several threads can access it concurrently. You should know that re...

When I started my career around two years back I encountered above listed queries. At that time I had no reply to these queries. But after dwelling around two years in IT sector I come along with some firm replies. All above listed questions are inter-belonging and the highlighted one was recently posted in a programmer's Q&A post, it inevitably raised my curious eyebrow. This can be a big debate. Diving straight to the point, the simple, unmistakable and well known answer is : “Developers are not very good testers.” But according to my understanding correct answer is, - “They don't want to see bugs in their code and only look for happy paths and and happy endings.” Believe me I was a developer in the past and then I moved to QA to avoid QA on my code, now I'm coding Automated Selenium Scrip...
