    1. What Is Ollama? Ollama is a lightweight runtime that allows you to run large language models (LLMs) locally on your own machine. Instead of calling cloud-based APIs (like OpenAI or Anthropic), Ollama enables you to download open-source models and perform inference completely offline. In simple terms: 2. Why Ollama Exists Most Generative AI tutorials…

    When studying the JVM and its Just-In-Time (JIT) compilation process, one important component to understand is the code cache.This cache stores the optimized native machine code generated by the JIT compilers.Knowing how the code cache works, how to inspect it, and how to tune its size can help improve application performance, especially in large or…

    1. JVM Has Two JIT Compilers: C1 and C2 Modern JVMs include two different compilers, each with a specific purpose: C1 (Client Compiler) C2 (Server Compiler) This structure is known as tiered compilation, and it dramatically improves how Java warms up and stabilizes performance. 2. Understanding Compilation Levels (Tiers) Every compiled method receives a compilation…

    When you run a Java application, the JVM does not immediately compile everything into optimized machine code. Instead, it dynamically profiles, interprets, and JIT-compiles parts of your program based on how frequently they are used. To see exactly what the JVM is compiling, the JVM provides a powerful diagnostic flag: -XX:+PrintCompilation This option prints every…

    Java’s performance story is often misunderstood. Many people hear: “Java is interpreted, so it must be slow.” But the truth is far more interesting. The JVM does not behave like a simple interpreter. It is a sophisticated, intelligent, adaptive execution engine capable of learning how your program behaves and optimizing itself continuously. 1. The Initial…

    1. The Java Execution Pipeline: Bytecode is Key The journey from writing human-readable Java code to its execution is a two-step process, designed to provide consistent, reliable performance across diverse hardware. Step A: Compilation When you write code in Java (.java files), it is first processed by the Java Compiler. Step B: Execution When you…

    gRPC is a high-performance, open-source communication framework designed by Google for efficient communication between distributed systems. It is especially popular in microservices, cloud-native architectures, IoT, and low-latency systems. 1. What is gRPC? gRPC stands for Google Remote Procedure Call. It allows a service running on one machine to directly invoke a method on another machine…

    1. Introduction: What Does Linear Regression Try to Achieve? Linear regression is one of the most fundamental tools in statistics and machine learning. Its purpose is simple—but extremely powerful: To model how multiple input variables influence a single output, using a linear equation. This makes it useful in a huge range of fields—economics, finance, engineering,…
