There are a good number of articles that articulate functional differences between HashMap, HashTable and ConcurrentHashMap. This post compares the performance behavior of these data structures through practical examples. If you don’t have patience to read the entire post, here is bottom line: When you confront with the decision of whether to use HashMap or HashTable or ConcurrentHashMap, you can consider using ConcurrentHashMap since it’s thread-safe implementation, without compromise in performance.

Eclipse and IntelliJ are the two competing IDEs in the industry. There are lot of passionate discussion going in the social media, forums to declare the winner in this race. We thought it would be a fun exercise to study which IDE utilizes memory efficiently?

Continuous Integration/Continuous Deployment (CI/CD) has become central to software development. To ensure high-quality software releases smoke tests, regression tests, performance tests, static code analysis & security scans are run in CI/CD pipeline. Despite of all these quality measures, still OutOfMemoryError, CPU spikes, unresponsiveness, degradation in response time are surfacing in production environment.

HeapHero’s JSON APIs are used for application monitoring, analyzing code quality during CI/CD pipeline and several other purposes. API response contains rich set of information (i.e. lot of elements). In this article, we intend to highlight to few key elements in the API response. If values of these elements exceed or drops below the certain threshold, then you might consider raising alerts/warnings
