Overview Git is a version control system that manages and tracks changes in projects. Unlike traditional systems, Git stores data as snapshots of the project rather than as a series of file changes. This approach allows Git to perform most operations locally, making it fast and efficient. It ensures data integrity through checksums and primarily adds data, making it difficult to lose information. Git operates with three main states: modified, staged, and committed, correspond

Machine learning models often face the challenge of generating sequences, such as sentences, code, or even music. Selecting the best possible sequence from many candidates is a complex task. Beam search is a powerful algorithm that helps models find high-quality sequences efficiently. This post explains what beam search is, how it works, and where it is used in machine learning. What Is Beam Search? Beam search is a heuristic search algorithm used to explore possible sequence

The perceptron is one of the simplest yet most important concepts in machine learning. It laid the foundation for modern neural networks and deep learning, which power many technologies we use today. Understanding the perceptron helps machine learning enthusiasts grasp how computers can learn from data and make decisions. This post explains what a perceptron is, how it works, and why it remains relevant. What Is a Perceptron? A perceptron is a type of artificial neuron, inspi

Choosing the right infrastructure for your applications can be challenging. With options like bare metal servers, virtual machines (VMs), and containers, each offers unique benefits and trade-offs. Understanding these differences helps you build a system that fits your performance needs, budget, and management preferences. This post breaks down the key features of bare metal, VMs, and containers. It explains how they work, their advantages and disadvantages, and when to use e

What is Liquibase? Liquibase  is an open-source "version control for your database." Just as Git tracks changes to your application code, Liquibase tracks changes to your database schema (tables, columns, indexes). In traditional development, managing database changes is often manual and risky: one developer runs a CREATE TABLE  script locally but forgets to give it to the team, or the production database drifts out of sync with development. Liquibase solves this by treating

Identity Federation Identity Federation refers to a system that allows the sharing of identity information across different domains or organizations. This enables users to access multiple services or applications using a single set of credentials, enhancing both security and user experience. Identity federation emerged towards the end of the first decade when Facebook and Google allowed various sites to utilize their services for authorization to access specific user data. B
