How to Build a Production-Ready Registration System Without a Backend (Using HosteDay API)

Introduction Building a complete registration system usually means setting up a backend, managing authentication, handling validation, and securing endpoints. But what if you could skip all of that? In this tutorial, you’ll build a production-ready user registration system by connecting a simple frontend directly to the HosteDay API—no backend required. Instead of focusing on infrastructure, you...

Code In, Cluster Out: Building Reproducible Edge Kubernetes with NixOS, K3s, and Forgejo

What if your entire Kubernetes edge cluster, from the kernel to the workload, was a single reproducible function? No drift. No snowflakes. No, "this node got fixed manually six months ago, and nobody remembers how." Just code in, cluster out. That question led me into a project that combines: infrastructure-nixos for the Raspberry Pi-hosted Forgejo control path edge-cluster-infra for Oracl...

AI security monitoring at scale: one LLM call, every dashboard

How CoinHawk runs a continuous AI security scan for every connected user using a single shared LLM call every 5 minutes. The dumb version doesn't scale Imagine you want every user's dashboard to display a live "security score" produced by an LLM. The first instinct is: GET /api/security/scan → call OpenAI → return result If 1,000 users hit the dashboard, you make 1,000 ...

Is a Data Science Bootcamp Worth It in 2026?

If you’re typing data science bootcamp worth it into Google, you’re probably torn between spending a few hundred (or a few thousand) dollars and spending months piecing together learning from YouTube and random notebooks. The real question isn’t “can I learn data science online?”—you can. It’s whether a bootcamp is the fastest, most reliable path for your constraints (time, budget, accountability,...

Verifying real wallet ownership without gas: a signed-nonce pattern with viem + Express

A production walkthrough of the auth pattern powering CoinHawk's admin layer — and why "the client says they're 0xABC" is a security bug. The naive way (and why it's broken) When a user connects MetaMask to your dapp, the browser hands you their wallet address through window.ethereum.request({ method: "eth_requestAccounts" }). Tempting flow: Frontend asks MetaMask for the address ...

How I built an AI crypto trading dashboard in a weekend with Replit + Base

A practical breakdown of CoinHawk: what it does, how it's wired, and what surprised me along the way. I've been trading crypto on the side for about three years and the same thing kills me every time: I miss the move. The signal hits at 3am, my Discord pings, I'm asleep, and by the time I wake up the trade is gone. So last weekend I built CoinHawk — an AI-powered trading dashboard that watche...

Is a Data Science Bootcamp Worth It in 2026?

If you’re asking data science bootcamp worth it, you’re probably feeling the same pressure everyone does: the job posts want “experience,” your timeline is tight, and YouTube tutorials aren’t a plan. Bootcamps can work—but only for a specific type of learner with a specific goal. What “worth it” actually means (ROI, not vibes) A bootcamp is “worth it” if it compresses your time-to-comp...

Is a Data Science Bootcamp Worth It in 2026?

If you’re googling data science bootcamp worth it, you’re probably not asking whether data science is real—you’re asking whether a bootcamp can realistically get you hired (or promoted) without wasting months and thousands of dollars. What “worth it” actually means (ROI, not vibes) A bootcamp is worth it when it compresses time-to-skill and time-to-opportunity. Here’s a practical ROI ...

From Netdata Inspiration to SaaS MVP: Server Monitoring with Bun + Claude Code Opus 4.6

If you've ever set up Netdata, you know that feeling — hundreds of real-time charts, per-second granularity, metrics you didn't even know your kernel exposed. It's a wonderful piece of software, genuinely one of the best open-source monitoring tools out there. But here's the thing: I run a small fleet of CDN servers. I don't need 2,000 charts. I need to glance at a single dashboard and know: are ...

My Database Disappeared Every Time I Restarted Docker. Migrations Fixed That.

In Part 8, I ripped out SQLite and switched to Postgres. The database was real now — but it still only ran on my laptop. Three terminal tabs. One for go run, one for Redis, one for Postgres. If I closed any of them, the whole thing fell over. It was time to Dockerize. The First Dockerfile: 800MB of Regret My first attempt was a single-stage Dockerfile. Copy everything, build, run: ...
