The InetAddress.getLocalHost() method can be slow in certain environments because it performs a reverse DNS lookup to determine the hostname of the local machine. Here’s why this might be happening and potential solutions: Reasons...
Here’s a simple example of how Merkle trees work for data replication in a scenario where the root hash of the two nodes differs due to missing or changed keys in one of the...
Lets break down the concepts of Gossip protocol for node failure detection with a simple step-by-step example and provide a visual overview of how the information propagates. Here’s how a basic failure detection system...
In an era where containerization has become a standard in software deployment, it’s increasingly important for applications to be able to identify when they’re running within a containerized environment. Whether you’re monitoring resource usage,...
n modern cloud-native environments, applications are often containerized, either using Docker or orchestrated within Kubernetes clusters. Retrieving the container ID of the currently running container programmatically can be useful for debugging, logging, or tracking...
Consistent Hashing is a technique used primarily in distributed systems to efficiently distribute data across multiple nodes. It addresses the challenges of load balancing and data distribution, particularly when nodes are added or removed...

In Java, you can check if the current system is running on a virtual machine (VM) by inspecting certain system properties or by checking for specific indicators in the environment. While there’s no direct...
To check whether the Docker daemon is running over TLS (port 2376) or without TLS on port 2375, you can make an attempt to connect to both ports and see which one is available....
This code snippet is a great approach to listen for Docker events, particularly the stop events, using the HttpClient in Java without relying on a Docker client library. The code makes use of the...
