Java Threads

 Java is a computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but it has fewer low-level facilities than either of them. As of 2019, 3 billion devices run Java.

How to Check if Someone is Connected to Your Machine in Linux

Picture this: you glance at your system monitor and notice your CPU is humming along even though you're not running anything demanding. Or maybe your internet feels sluggish for no obvious reason. A small, uneasy thought creeps in — is someone else on my machine right now? For Linux users, this isn't something you have to wonder about. Linux ships with a powerful set of built-in tools that let you see exactly who's connected, who's logged in, and what your network is doing at any given moment. You don't need to be a security expert to use them — you just need to know where to look. This guide walks you through the practical, no-nonsense steps to check for unauthorized connections on your Linux system, with real commands you can run right now. Why Monitoring Network Connections Matters Every device on a network — including your own Linux machine — communicates using an IP address. When another device or user connects to your system, that connection shows up as a trac...

How to Set Up a Linux Web Server and Host an HTML Page Easily

Setting up a web server on Linux means spending a fair amount of time in the terminal — Linux leans heavily on the command line rather than clicking through menus, so you'll be typing out instructions more often than not.  If you're new to this, it can feel a little intimidating at first, but the good news is you don't need to become a Linux wizard overnight. A handful of core commands will get you surprisingly far. A few you'll lean on constantly: cd — move between directories ls — see what's in the current directory mkdir — create a new folder nano or vim — edit files right there in the terminal sudo — run something with administrator privileges Get comfortable with these and you'll be able to navigate around, tweak configuration files, and install software without much trouble. You don't need to memorize everything — you just need to be confident enough to follow along with clear instructions, which is exactly what this guide aims to give you....

C++ vcpkg Manifest Mode + CMake

 If you've ever tried to install a C++ library and felt like you were assembling furniture without instructions, this article is for you. We're going to talk about vcpkg manifest mode and how it works with CMake , and I'm going to explain it like you're five years old (in a good way — no judgment here). First, Let's Talk About the Problem In most programming languages, adding a library is easy. Python has pip install requests . JavaScript has npm install express . You type one command, and boom, the library shows up in your project. C++ never really had that. For decades, if you wanted to use a library like fmt or nlohmann/json , you had to: Download the source code yourself Figure out how to compile it Tell your compiler where to find the headers Tell your linker where to find the compiled binaries Cry a little vcpkg is Microsoft's answer to this mess. It's a package manager for C++ — like pip or npm , but for C++ libraries. And manifest mode...
