Cloud Computing Basics: Service and Deployment Models Broken Down for Beginners

·3 views

A developer has launched a daily blogging series on AWS and DevOps, with Day 1 covering the fundamentals of cloud computing. Cloud computing, as defined by NIST, enables on-demand access to a shared pool of configurable computing resources over the internet, replacing the need for costly on-premises infrastructure. The three main service models are IaaS, PaaS, and SaaS, each progressively shifting more management responsibility from the user to the cloud provider. Deployment models include public, private, hybrid, and community clouds, each offering different trade-offs between cost, security, and control. The series is set to continue with Day 2 focusing on client-server architecture.

Plan 9: The Forgotten OS from Bell Labs That Quietly Shaped Modern Computing

Plan 9 was an operating system developed by Bell Labs in the late 1980s and early 1990s by the same team behind Unix, including Ken Thompson and Dennis Ritchie. Rather than patching Unix's growing complexity, the team started from scratch with a radical design principle: everything, without exception, is a file. Its core protocol, 9P, allowed windows, network connections, and remote machines to all be accessed as filesystem entries, making distributed computing remarkably simple. Plan 9 also introduced per-process namespaces, where each process could have its own independent filesystem view — a concept that directly inspired Linux namespaces and, by extension, modern container technologies like Docker. Although Plan 9 never achieved mainstream adoption, its foundational ideas continue to influence the operating systems and developer tools used widely today.

CleanSlate: Open-Source Coding Agent Runs Across IDE, CLI, and SDK

A developer has launched CleanSlate, an open-source platform designed to run coding agents on both local machines and the cloud. The tool currently supports IDE, CLI, and SDK interfaces, allowing agents to read codebases, make edits, execute commands, browse the web, and validate their output. CleanSlate is model-agnostic, meaning it is not locked into any single AI provider or ecosystem. The team is working on longer-running autonomous cloud agents that can operate independently without requiring the user's machine to stay active. The project is in early stages, and the developer is seeking feedback from the developer community via GitHub and its official website.

Fluentic Style tackles CSS debugging across Next.js server and client boundaries

Developer Fluentic Style is a CSS-in-JS styling library designed to maintain a consistent debugging experience across both server and client environments in Next.js App Router. The core challenge is that Next.js splits rendering across React Server Components, client components, streamed HTML, and hydration, making a unified CSS debugging model difficult to achieve. The library addresses this with a two-part approach: ensuring server-rendered HTML is already styled on initial load, and having the client runtime collect debug metadata to maintain sourcemap and DevTools tracing after hydration. The goal is to keep the same atomic CSS authoring API and developer tooling whether the code runs in a simple single-page app or a full Next.js App Router setup. The integration layer is designed to be transparent, so developers do not need to change their styling code based on the rendering environment.

Teen Hitmen Being Recruited to Carry Out Contract Killings Across Europe

A troubling trend has emerged across Europe involving the recruitment of teenagers to carry out contract killings. Criminal networks are reportedly targeting young people, exploiting their vulnerability and offering money in exchange for committing violent acts. The phenomenon has been documented across multiple European countries, raising serious concerns among law enforcement agencies. Authorities are investigating how these networks identify and groom minors for such dangerous criminal activity. The trend highlights growing challenges in tackling organized crime that increasingly uses juveniles to evade harsher adult sentencing.
