First look: Fi Ultra Starlink pet tracker

Fi Ultra is the first Starlink-enabled pet tracker you can buy. It expands on GPS and LTE trackers, adding automatic failover to T-Mobile's T-Satellite-branded direct-to-cell service when venturing into cellular dead zones. That lets owners tap into SpaceX's constellation of low Earth orbit Starlink satellites to track their pets anywhere in the US. But it […]

#8 Six Teams, Six Different Forms: My First Real Project

The therapy unit at the hospital I work for had six treatment rooms. Room 1, Room 2, Room 3, and so on, each split by the kind of therapy it handled. And each room kept its own document to record patients. The problem wasn't that the documents existed. The problem was that no two of them looked alike. Same patient. Same information. But every room ordered the columns differently and named things differently. One put the date in the first column. Another put it last. One wrote "treatment time." The room next door wrote "minutes used." On their own, each form worked fine. Looked at one at a time, there was nothing wrong. The trouble showed up the moment anyone tried to combine them. The work that never ended Every so often, a request would come down from above: Can we see the overall numbers? That was when the real work began. I would open all six documents side by side. I would line up columns that didn't match, by eye, and move each value into one master table by hand. Days of this would get me a single sheet of statistics. Then the next quarter, the same request came down again. And I started over. The table I'd built last time was useless if the format had shifted even slightly. So I rebuilt it from scratch. Every time. I couldn't stand it. This was obviously a job you do right once and never touch again. We just weren't doing it right. So instead, we kept feeding people's evenings into it. The obvious answer The fix was simple. Make all six rooms use one form. Same columns. Same names. Same order, everywhere. Then there's nothing to move when you combine them. The statistics become a matter of stacking, not translating. The answer was so obvious I wondered why nobody had done it years ago. So I built a unified form in Excel and sent it around. And that's where I learned Excel has walls of its own. Where Excel broke down Once a file gets passed around, you lose track of which copy is the real one. The versions pile up. "Final." "Actually final." "Final, revised."

We Built the Digital Age on Something We Still Don't Fully Understand. AI Is No Different.

Quantum mechanics gave us the transistor before we understood it. The same pattern is happening with AI right now — and the builders who recognize this will define what comes next. The argument that never ended — and the lab that didn't care In 1927, the greatest minds in physics gathered in Brussels for the Solvay Conference. Albert Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, Max Planck, Marie Curie — twenty-nine of the most brilliant humans who ever lived, in one room. They were arguing about quantum mechanics. Specifically: what does it mean for a particle to exist in multiple states simultaneously until observed? Does reality require an observer? Is the universe fundamentally probabilistic? Is God playing dice? Einstein said no. Bohr said yes. Neither convinced the other. That argument never fully resolved. Nearly a century later, physicists still debate the interpretation of quantum mechanics — the Copenhagen Interpretation, Many Worlds, Pilot Wave theory. We have not settled it. Meanwhile, in 1947 — twenty years after the Solvay Conference — three engineers at Bell Labs in New Jersey quietly invented the transistor. William Shockley, John Bardeen, and Walter Brattain did not wait for the philosophical debate to conclude. They did not need to understand why quantum tunneling worked at a fundamental level. They understood it well enough to build something with it. That transistor became the foundation of every computer, every smartphone, every server, every piece of digital infrastructure that exists today. We built the entire digital civilization on something we still don't fully understand. Not despite the uncertainty. With it. The pattern repeating right now Across the internet in 2025 and 2026, a remarkably similar argument is happening. Will AI take all the jobs? Is it conscious? Does it hallucinate too much to be trusted? Are we building something we cannot control? Should we slow down? Should we stop? These are not trivial questions. The r

Day 02: The Terminal, Shells & File Systems

🎯 Learning Objectives Understand the interface boundary between Terminal Emulators and Shell Interpreters (including Windows Terminal vs. PowerShell vs. CMD). Master File System path tracking, hidden dotfiles, and essential CLI utilities. Map system execution paths via global and local environment configurations. 1. Terminal vs. Shell (The Windows Architecture) Terminal: The visual GUI wrapper. A window application that captures keyboard strokes, handles GPU text rendering, and manages tabs/panes. Examples: Windows Terminal, iTerm2, Alacritty. Shell: The command interpreter engine running inside the terminal. It evaluates text strings, processes scripts, issues system calls ( syscalls ), and interacts with the OS Kernel. Examples: PowerShell, Bash, Zsh, Command Prompt (CMD). ┌────────────────────────────────────────────────────────┐ │ WINDOWS TERMINAL GUI (The Visual Interface Window) │ │ │ │ │ ├───► Tab 1: [ PowerShell Core Engine (Modern) ] │ │ ├───► Tab 2: [ Command Prompt Engine (Legacy) ] │ │ └───► Tab 3: [ WSL Ubuntu Linux Bash (Core) ] │ └───────────────────────────┬────────────────────────────┘ │ Raw Text & Input Streams ▼ ┌────────────────────────────────────────────────────────┐ │ SHELL INTERPRETER (e.g., PowerShell / CMD) │ │ └───► Parses input string commands into system tasks │ └───────────────────────────┬────────────────────────────┘ │ System Call (Syscall) ▼ ┌────────────────────────────────────────────────────────┐ │ OPERATING SYSTEM KERNEL │ │ └───► Interacts directly with underlying hardware │ └────────────────────────────────────────────────────────┘ 2. Deep Dive: PowerShell vs. Command Prompt (CMD) While both are Windows shells hosted inside Windows Terminal, they belong to entirely different computing eras: Command Prompt ( cmd.exe ): A legacy text shell maintained purely for backwards compatibility with 1980s MS-DOS. It pipelines data as Plain Text Only , meaning outputs must be manually string-filtered. PowerShell ( pwsh.exe ): A modern, cros

Why AI Will Not Replace Teachers, But It Will Change the Way Students Learn

Artificial intelligence has become one of the most discussed technologies in education. From automated grading systems to AI chatbots capable of answering complex questions, many people wonder whether AI will eventually replace teachers. The short answer is no. Education has never been just about delivering information. Great teachers inspire curiosity, understand students' emotions, adapt to different learning styles, and create environments where learners develop critical thinking. These are deeply human abilities that artificial intelligence cannot fully replicate. However, AI is beginning to solve a different problem: helping students learn independently outside the classroom. The Problem With Traditional Self-Study Many students spend hours reading textbooks without truly understanding the concepts. When they encounter a difficult paragraph, they often search the internet, only to find lengthy articles, conflicting explanations, or answers that are either too advanced or completely unrelated to their curriculum. This creates an inefficient learning process where students spend more time searching than actually learning. Another common challenge is passive learning. Reading a chapter once often creates the illusion of understanding, but without testing knowledge through questions or applying concepts, much of that information is quickly forgotten. How AI Can Support Learning Modern educational AI systems are becoming less like search engines and more like interactive learning companions. Instead of simply returning search results, these systems can explain concepts in simpler language, adapt explanations to a student's academic level, answer follow-up questions, generate practice quizzes, and even identify areas where additional practice is needed. This creates a much more personalized learning experience. Learning From Personal Study Materials One of the most interesting developments in AI education is the ability to work with a student's own resources. Rather

AI Coding Agent ROI: What Enterprises Should Measure Beyond Code Generation

Enterprises are now talking about AI coding agents in a very predictable way. The first question is usually: "How much more code can it help us generate?" It is not a wrong question. But if that is the only question, the ROI calculation will probably be wrong. Because enterprises are not really buying "more code." They are buying: faster delivery less rework lower maintenance cost better developer experience more stable software quality more controllable security and compliance risk faster translation from product capability to business value Code generation is an input. It is not the outcome. That distinction matters. An AI coding agent can help developers write functions, fix bugs, add tests, generate documentation, understand codebases, and refactor legacy systems. That sounds powerful. But the enterprise question is not: "How many lines of code did it generate today?" The better question is: Did that code reach production faster? Did incidents go down? Did the team spend less time on repetitive work? Did customers get value sooner? If the answer is unclear, generating 100,000 lines of code a day may simply mean producing technical debt faster. The short version: AI coding agent ROI does not end inside the IDE Many teams start measuring AI coding tools with the most obvious numbers: code suggestion acceptance rate lines of code generated number of active users number of prompts time saved on individual tasks These metrics are useful. But they mostly show that the tool is being used. They do not prove that the enterprise is getting value. Enterprise ROI has to be measured across software delivery, quality, risk, and business outcomes. In other words, an AI coding agent is not just a point solution for individual efficiency. It affects the entire software value stream: Request -> Design -> Coding -> Review -> Testing -> Deployment -> Monitoring -> Feedback -> Business outcome If you calculate value only inside the "coding" box, you miss the bigger picture. Why "amo

Why I Choose Lovable for Building Full-Stack Applications with AI

Why I Choose Lovable for Building Full-Stack Applications with AI Over the last year, AI-assisted software development has evolved from generating code snippets to building complete web applications. We've all seen tools like Cursor, Claude Code, GitHub Copilot, Replit Agent, Bolt, and many others enter the market. Each has its strengths, but after experimenting with several of them, I keep coming back to Lovable whenever I want to build a new web application from scratch. This isn't a sponsored post—it's simply the workflow that has worked well for me. If you're interested in trying Lovable, you can use my referral link below. Disclosure: new users receive additional signup credits, and I receive referral credits if you sign up through it. Referral: https://lovable.dev/invite/AQ02SOZ Why Lovable Stands Out Most AI coding assistants help you write code. Lovable helps you build an application. Instead of focusing on individual functions or files, it takes a higher-level approach where you describe what you want, and it generates a complete full-stack application that you can continue refining. A typical workflow looks like this: Idea │ ▼ Describe the application │ ▼ Lovable generates • Frontend • Backend • Database • Authentication • API integration │ ▼ Preview instantly │ ▼ Connect GitHub │ ▼ Iterate and Deploy Unlike traditional no-code platforms, you're not locked into a proprietary editor. Lovable supports GitHub synchronization, native Supabase integration for authentication and PostgreSQL-backed data, and deployment options ranging from Lovable-hosted apps to your own infrastructure. Why I Keep Choosing Lovable After building several side projects, these are the reasons I continue to use it. 1. Rapid idea-to-production workflow The biggest productivity gain isn't AI-generated code. It's reducing the number of decisions needed before users can interact with your application. Instead of spending hours creating project structure, authentication, routing, database

Keeping context and decisions consistent across parallel AI agents

You start the morning with four Claude Code agents running, each in its own git worktree, each on a separate task. By mid-afternoon something is off. One agent has re-implemented a helper another already wrote. A second built against an interface that a third changed an hour ago. A fourth made a naming choice that contradicts a decision you made — out loud, to yourself — at 9am. Every diff is reasonable on its own. The system they add up to is not. This is the failure mode that shows up the moment you go from one agent to several. The code each agent produces is fine. What drifts is everything between the agents: the decisions, the conventions, the current shape of the interfaces they all depend on. Running the agents in parallel is the easy part. Keeping them coherent is the hard part, and it's a different problem. Why parallel agents drift An agent's context is per-session. Each Claude Code instance has its own context window, populated by what it has read and done in that session. Nothing about that window is shared with the agent running in the next worktree. There is no common memory they all write to and read from. So when agent A decides "we use the repository pattern for data access," that decision exists in exactly two places: agent A's context, and your head. Agent B never hears about it. Three kinds of state cause the drift, and they're worth separating because they need different handling: Decisions already made. Architecture, naming, conventions, the approach you settled on for a cross-cutting concern. These are durable — once made, they should bind every agent, including ones you spawn tomorrow. The current contract. The shape of the interfaces, types, and APIs that agents share. This changes during the work: agent A edits a signature, and agents B and C are now building against a version that no longer exists. What's in flight. Who is touching which files right now. Two agents editing the same module in separate worktrees won't see each other until th

The Steam Machine fits my TV, my desk, and my life

For the last couple weeks, I've been in an extremely lucky position: I've been spending a lot of time playing games on Valve's Steam Machine. We gave the Steam Machine a 6, and I don't disagree with my colleague Sean Hollister's review. But even though I already own a PS5 and an Xbox Series X, […]
