Demystifying Docker: How It Works

stp2y0 CommentsNewscoding, community, containers, development, docker, engineering, inclusive, learning, software

Docker is a containerization tool that uses lightweight virtualization to create isolated environments called containers. Unlike virtual machines (VMs) which emulate entire operating systems, Docker containers share the host's kernel, making them faster and more efficient. What We’ll Cover An exploration of Docker’s core concepts, including images, containers, and networking. Insights into how Docker works under the hood, such as namespaces, cgroups, and the Docker architecture. Practical examples to reinforce key concepts, like running containers and inspecting images. Why Docker Matters Docker plays a big role in modern IT: Consistency: Ensures applications run the same across all environments. Efficiency: Containers…

Dev Log #15 – Collisions

stp2y0 CommentsNewscoding, community, development, devjournal, engineering, gamedev, inclusive, learning, programming, software

Today I kept working on my gamified portfolio site with Phaser.js. Progress I've started creating Scenes for the buildings' interiors. One challenge that immediately became apparent was how to make the player aware that they were close to the exit and could action it to leave the building. I've opted for creating an invisible rectangle and using tweens to animate the player's sprite color as a signal. It's neat and I can reuse the code for all buildings. Whereas previously I was using one unique tile for the Game scene's terrain, I've now randomised to create a more organic-looking landscape.…

In the world of professional software development, teams rely on Git to manage their version control systems. However, not all processes go smoothly. At times, discrepancies arise between pull requests and the remote branch, leading to situations where merging the branch into production is not feasible. This is where cherry-picking comes to the rescue. This article explores cherry-picking, its significance, real-life scenarios that warrant its use, and the commands and steps to implement it effectively. What is Cherry-Picking? Cherry-picking in Git refers to the process of selecting specific commits from one branch and applying them to another branch. Unlike merging…

Understanding CSMA/CD and CSMA/CA in Networking

stp2y0 CommentsNewsbasic, coding, community, development, devops, engineering, inclusive, learning, networking, software

In networking, efficient and fair use of shared communication channels is critical to minimizing data collisions and maximizing network performance. Two foundational protocols that manage network access in this context are Carrier Sense Multiple Access with Collision Detection (CSMA/CD) and Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). These protocols are essential to network performance, particularly in Ethernet (for CSMA/CD) and wireless (for CSMA/CA) environments. Let’s dive into the details of how each protocol works, where it’s used, and its significance in network management. What is CSMA? Carrier Sense Multiple Access (CSMA) is the overarching method that allows devices on…

Introduction Learn how to get started with file globbing by creating a console project to list all Visual Studio solutions (.sln) under a specific folder along with project names for the solution exported to a json file. The reason for using solution and project files is that every reader here using Microsoft Visual Studio should have at least two while if the example were for Word documents or specific image types the code presented may not work so well. Other opportunities besides using a conventual console project there are commandline dotnet tools C# .NET Tools with System.CommandLine which the code…

Top 5 Game-Changing JavaScript Features in ECMAScript 2024: Boost Your Code Like Never Before!

stp2y0 CommentsNewscareer, coding, community, development, engineering, frontend, inclusive, javascript, learning, software

1. Top-Level await – Async Simplified! Gone are the days when async code required wrapping everything in functions. With top-level await, we can directly use await in modules without needing an async function wrapper. This feature is particularly handy for simplifying code and reducing boilerplate Before top-level await, fetching data required an async function: async function fetchData() { const response = await fetch('https://api.example.com/data'); const data = await response.json(); return data; } fetchData(); Enter fullscreen mode Exit fullscreen mode Now, with top-level await, we can call await at the root level: const response = await fetch('https://api.example.com/data'); const data = await response.json();…
