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...
As of now (2024), here’s the current status of Bitcoin generation, the size of the blockchain, and number of transactions: 1. How Many Bitcoins Have Been Generated? 2. How Big is the Bitcoin Blockchain?...
The difficulty target in blockchain networks like Bitcoin is set automatically by the network protocol. It’s not set by any individual or central authority. Here’s how it works: 1. Automatic Difficulty Adjustment 2. How...
In blockchain mining, particularly for Proof of Work (PoW) blockchains like Bitcoin, the puzzles that miners solve are complex mathematical problems called cryptographic hash puzzles. These puzzles are not like traditional puzzles; they don’t...
Here’s a simple Java code example to detect clock skew by comparing your system’s current time with the time from an NTP server. Java Code to Detect Clock Skew Using an NTP Server You’ll...
