01 — Getting Started: Run Your First Local LLM (5 Minutes) 🟢 Beginner — No experience needed. Just a computer and 5 minutes. What Is a Local LLM? (Plain English) An LLM (Large Language Model) is the brain behind ChatGPT, Claude, and Gemini. A local LLM runs that brain on your own computer — not on someone else's server. Why does that matter? Cloud AI (ChatGPT, Claude) Local AI (Ollama + models) $…

Hi DEV Community, I’m a student developer currently building a P2P marketplace for high-quality digital study materials. We’ve all seen how centralized Web2 platforms squeeze creators and buyers with 15-20% commissions and frustratingly slow payout cycles. I'm designing a Web3 protocol to cut this friction to the bone, but I’m currently wrestling with the long-term sustainability model and infras…

I shipped an AI readiness self-check for California court staff, ThemisLex.org . Here is the why behind it. The problem, the design choices, and what four weeks of building in public actually gave me. I've written a few posts about building Themis Lex. The deploy war story got the most attention. What I never did was stop and explain why the thing exists in the first place. So before the Women in…

The Moment That Changed My Mind There's a moment every developer knows. You're staring at a task that should take ten minutes, but somehow you're on hour three chasing a bug through three files, two APIs, and a Stack Overflow thread from 2019. You're not building anymore. You're just surviving. That was me last week. And then I opened Google Antigravity 2.0. I went in skeptical. I've seen "AI cod…

This is a submission for the Google I/O 2026 Writing Challenge Everyone's excited about Gemini in Firebase. Almost nobody's talking about how to secure it. That's a problem. Firebase AI Logic lets you call Gemini directly from your client app—no backend server needed. That's powerful. It's also dangerous. The moment you put an AI endpoint on the internet, you've created an attack surface that mos…

02 — Hardware Guide: What Do You Actually Need? 🟢 Beginner — No matter what computer you have, there's a model that will run on it. The Most Important Thing to Know VRAM is the bottleneck, not compute. A model running on a 5-year-old RTX 3060 at Q4 quantization gives you 96% of the quality of the same model on an A100 — just slower. And "slower" for most use cases (chat, coding, document analysis…

The Problem You've built an autonomous AI agent. You've given it constraints—readonly rules it cannot modify. One rule might be: "Never auto-clear the human pause flag." Good. That prevents runaway behavior. But now a legitimate edge case appears. The human explicitly grants authority for one specific action that would violate the constraint. The agent is stuck: Option A : Read around its own doc…

The Problem We Were Actually Solving At its core, our Treasure Hunt Engine is a web-based game that generates treasure maps for users to solve. It's a simple concept, but one that relies heavily on caching, load balancing, and database performance. As our user base grew, so too did the pressure on our system. But the problem wasn't just about scaling up the infrastructure - it was about understan…

Open WebUI: Your Local ChatGPT Transform your local LLM into a beautiful, full-featured web interface — like ChatGPT, but running entirely on your machine. What Is Open WebUI? Open WebUI is a self-hosted web interface for Ollama. It gives you: 🖥️ A ChatGPT-like chat interface in your browser 🔄 Switch between models mid-conversation 📁 Upload documents and chat with them (RAG) 🖼️ Image generation (…

If you are building a UI that needs to show progress, logs, or live updates, you do not need to jump straight to WebSockets. In many cases, SSE is the simpler and more appropriate choice.It is a browser-friendly way for the server to push events to the client over HTTP. Think of it as a one-way live stream: the server sends updates, and the browser listens. SSE is a great option when you need ser…

The volume presents the abstracts of the 10-th annual Moscow International seminar “Transcendental Turn in Modern Philosophy – 10: Metaphysics and Meta-Metaphysics, Transcendental Semiotics, Cognitive Science and Artificial Intelligence”, dedicated to the connection and influence of transcendentalism on modern: metaphysics, transcendental semiotics, cognitive sciences and research in the field of…

We argue that four-dimensionalists should adopt a contextualist semantics about ‘I’, according to which tokens of ‘I’ sometimes refer to stages, sometimes to segments, and sometimes to worms. Our argument relies on an interpretive principle at the root of Kovacs’s diachronic self-making view, according to which ‘I’ refers to the candidate referent that maximizes the truth of an individual’s ‘I’-b…

Five times the bridesmaid, finally the bride, the Barcelona forward Ewa Pajor shrugged off the pain of all her Champions League final losses, scoring twice, as they punished a profligate Lyonnes to earn a fourth European title. Pajor stole the show, before Salma Paralluelo’s sublime double at the death doubled their tally. The Polish forward moved two goals clear of Alessia Russo’s nine to secure…

In damped SHM, we write: $$m\ddot{x} + b\dot{x} + kx = 0$$ The standard approach assumes a solution of the form $e^{\alpha t}$ and derives: $$\omega_d = \sqrt{\frac{k}{m} - \frac{b^2}{4m^2}}.$$ But ...

A recent study found that young adults experiencing mild psychotic-like symptoms also report higher rates of hypersexuality and problematic porn use. Experts suggest these sexual behavioral issues could act as early markers for severe mental health challenges.

I built my first MCP server last week and it was way simpler than I expected. Here is exactly how, no fluff. Prerequisites Node.js 20+ 10 minutes Step 1: Scaffold npx create-mcp-server my-first-server cd my-first-server npm install This generates a complete TypeScript project with one example tool. Step 2: Add your tool Open src/index.ts . Replace the hello tool with whatever you want: server . s…

React Native 0.85, much faster builds, and the one change that will probably break your imports._ Based on the official release notes: expo.dev/changelog/sdk-56 SDK 56 dropped on May 22, and I spent the weekend pulling one of my apps onto it. Most release notes read like a wall of changelog entries, so instead of repeating all of that, I want to walk through the handful of changes that actually s…
