Java Garbage Collection (GC) is the process of tracking the live objects while destroying unreferenced objects in the Heap memory in order to reclaim space for future object allocation. To understand GC well, it is good to have a solid...
Understanding Java Memory Model is an essential learning for serious Java developers who develop, deploy, monitor, test, and tune performance of a Java application. In this blog post, we are going to discuss on Java memory model and how each...
Understanding JVM architecture and how Java really works under the hood is an important learning for every Java developer in order to effectively make use of Java ecosystem. This blog post series will provide you a solid foundation on JVM...
Deciding what to choose for your next web API design There are so many classifications for APIs. But when it comes to web communication, we can identify two significant API types — Web Service APIs (e.g. SOAP, JSON-RPC, XML-RPC, REST) and Websocket APIs. But, what...
Understanding how HTTP works in the real world Disclaimer: This article focuses on explaining some underlying implementation details of HTTP, which will be helpful for readers to better understand my blog article — “HTTP and Websockets: Understanding the capabilities of today’s web communication...
A Java Heap Dump is a snapshot of the memory of a JVM process at a specific moment. Heap dumps can be taken in several file types, however the most-used type is HPROF binary format. The following are the typical information...
Java Profilers and APM (Application Performance Management) Tools provide the means of monitoring and debugging performance issues in development and production environments. In practice, most of Java developers use a combination of these tools to get their performance monitoring needs...

When we do software emulations in custom environments for testing and experimental purposes, we often depend on a Virtual Machine (VM) option like Oracle VirtualBox or VMWare, rather than using physical machines or cloud-based clusters. In general, a VM acts...
sudo(i.e. Super-user do) allows some users to execute some commands as root (or another user). According to Debian Wiki, using sudo is better (safer) than opening a session as root for a number of reasons, including: Nobody needs to know the root password (sudo prompts...
For those who hate the default color scheme in Ubuntu The default color scheme is the most annoying thing that I find in Ubuntu OS. When I get an Ubuntu machine, one of the first things I do is, customizing the...
