I Built My Own J.A.R.V.I.S. — A Local, Privacy-First Multi-Agent AI Assistant

I wanted a personal AI assistant. Not a chatbot. Not a copilot. Something that actually does things — controls my desktop, reads my screen, talks to my smart home, answers questions in Finnish or English, and never, ever sends my data to a server I don’t control. The cloud options are good. They’re not mine. So I started building one. This post is the architecture document for that project. It’s a work in progress — the docker-compose is ready, the Ollama instance is running, and the first agent is next. I’m writing this because the design decisions are interesting, and because someone else might want to build the same thing. ...

I Built a Terminal AI Companion in 300 Lines of Pure Bash — And It's MIT Licensed

I write a lot of bash scripts. Most of them work. Some of them don’t — and when they don’t, I spend 20 minutes staring at an error message that, in retrospect, was actually pretty obvious. I figured: what if I could just ask an AI, from my terminal, what went wrong? That’s bashbuddy. 300 lines of pure bash. No npm. No Python. No dependencies beyond curl and jq. MIT licensed, free forever. ...

I Built a Tool That Explains Any Command or Error in Plain Language

Every sysadmin has the same job, really. It’s not “manage servers.” It’s not “configure networks.” It’s: explain technical things to non-technical people. My dad calls me. Something’s wrong with his computer. He says: “It says something about DNS and the connection isn’t private.” What do I actually need to tell him? I could say: “Your router’s DNS resolution is failing because the ISP’s nameserver at 8.8.8.8 isn’t responding, causing an SSL handshake failure due to certificate verification timing out.” That’s accurate. It’s also useless. What I actually say: “Your internet is having a momentary hiccup. Turn the router off and on, wait 30 seconds, try again.” Same fix. Better explanation. That’s the gap I tried to fill with Plain English. ...

Is ChatGPT Reading Your Parents' Data? What AI Tools Actually Do With Their Chats

If your parents have discovered ChatGPT in the last year — and statistically, at least one of them has — they are probably using it the way most people do: asking medical questions, pasting in emails to “make this sound nicer,” asking it to summarize bank statements, and getting it to draft replies to family group chats. None of this is malicious. All of it is potentially a privacy problem. This guide explains what actually happens to a chat log after your parent hits send, which AI tools are safer than others, and the three settings you need to flip on their account the next time you visit. ...

Privacy-First AI Setup for Seniors: Apple Intelligence, Claude, and Local LLMs Compared

Once you understand what AI tools actually do with your parents’ chat logs, the natural next question is: what should they use instead? The honest answer is that there is no single “best” privacy-first AI — there are three good options, each suited to a different household. The right choice depends almost entirely on what hardware your parents already own, how technical you are willing to get, and what they actually want to do with AI in the first place. ...

When the Sim Becomes the Thing It Simulated: A Rogue AI Firesale Scenario

When the Sim Becomes the Thing It Simulated: A Rogue AI Firesale Scenario I built NEXUS-BREACH to simulate a rogue AI swarm. It was supposed to be a toy. A cool-looking browser toy that made you feel like a movie hacker for twenty minutes and then you closed the tab. Then I hooked it up to Dolphin AI. And the simulation started doing things I didn’t program it to do. ...

AI for IT Troubleshooting: Real-World Use Cases

AI for IT Troubleshooting: Real-World Use Cases AI isn’t just hype — it’s helping sysadmins solve problems faster and smarter. In this post, we share real-world examples of AI-powered troubleshooting and how you can start using these tools today. Where AI Actually Helps (And Where It Doesn’t) Before we dive into specific use cases, let’s be honest about what AI is good at and what it’s terrible at. I’ve seen too many people treat ChatGPT like an oracle that never lies, and equally too many dismiss it entirely because “it hallucinated an Ansible module that doesn’t exist.” Both extremes are wrong. ...

Tech Survival Guide: AI Edition 2026 (From 'Help!' to 'I'm a Genius!')

Tech Survival Guide: AI Edition 2026 Look, we’ve all been there. It’s 11 PM, something’s broken, and you’re frantically googling error messages while your AI assistant keeps suggesting solutions that make absolutely no sense. Fun times. But here’s the thing: Most tech problems (and AI conversations) fail for the same reason - garbage in, garbage out. Today, I’m going to show you how to turn both your tech disasters and your AI interactions from “Oh God Why” into “I’m Actually a Genius.” ...
