Day 76 of #100DayOfCode — Building DevBoard: REST API and UI Polish

Yesterday, DevBoard became a complete two-sided platform. Today I added two things that take it from a functional app to a portfolio-ready one: a REST API built with DRF, so the data is accessible programmatically, and UI polish using Tailwind CSS, so it actually looks like something you'd want to show someone. The REST API DevBoard's HTML interface works great for browser users. Bu...

Turning a Desk clock into a Claude Code usage meter

TL;DR — git clone … && ./install.sh <clock-ip>. Needs Claude Code signed in. macOS + Linux. Repo: github.com/shavindraSN/claude-meter. When you're deep in a coding session with Claude Code, the last thing you want is to hit a rate limit unexpectedly. The usage dashboard exists, but it's two clicks away — and checking it constantly breaks focus. Claude Code's paid plans have two r...

I Built a Real-Time Crowd Orchestration Engine for Stadium Events (PromptWar 2026)

The Problem: When 50,000 Fans Hit the Gates at Once Stadium bottlenecks aren't just annoying—they're dangerous. Static gate assignments fail when crowd dynamics shift. For PromptWar 2026, I wanted to solve this with code that actually thinks. The Build: PromptWar Crowd Orchestration Instead of rigid assignments, I built a 4-tier Human-Sensor Network that treats crowd managem...

The Discipline of Not Fooling Ourselves: Episode 5 — Compliance Without Causality

Why evidence that cannot explain is worse than no evidence at all. Where We Stand By this point in the drift, the system has achieved something that looks like stability. The right artifacts exist. Language is consistent. Ambiguity resolves quickly. Reviews proceed without friction. Audits return findings that are manageable, expected, and closed without difficulty. Nothing obvious is...

Mastering AI Model Fine-Tuning: Why You Should Stop Training From Scratch in 2026

The AI models of today are incredibly powerful. However, using a "vanilla" model is like hiring a genius who knows everything but understands nothing about your specific business. That is where Fine-tuning comes in—the essential bridge between a general-purpose AI and a production-ready expert. 🏗️ The Architecture: Training from Scratch vs. Fine-Tuning Why waste millions of dollar...

SQL Made Simple: A Beginner’s Guide to Understanding and Working with Data

If you’ve never worked with SQL before, start by thinking of a database like a very organized Excel sheet. It has rows and columns, but it’s built to handle large amounts of data much more efficiently. SQL (Structured Query Language) is the language used to communicate with that database. Instead of clicking around like you would in Excel, you write instructions, and the database responds. At fir...

300+ cold emails later… we got our first sponsor ($150)

I didn’t expect this to happen this early. After sending 300+ cold emails, getting ignored, ghosted, and honestly questioning if this idea even made sense… Apives just got its first sponsor. $150. It’s not a huge amount. But that’s not the point. The point is someone believed enough to pay. No investors. No network. Just persistence, late nights, and a lot of “seen but no reply”. There were ...

Telegram Bot Approvals: Mobile-First Transaction Signing for AI Agents

AI agents with crypto wallets need guardrails, but most developers bolt on security as an afterthought. The result? Agents that can drain wallets, approve unlimited token spending, or execute trades without human oversight when things go wrong. Why Security-First Matters The crypto space is littered with stories of smart contracts gone rogue, bots that emptied treasuries, and AI system...

Time Complexity and Big‑O Notation (Beginner Friendly Guide)

1. Introduction When we write a program, we often ask: Is my code fast enough? Will it work well when data becomes very large? To answer these questions, we use Time Complexity. Time Complexity helps us understand how the running time of a program grows as the input size increases. 2. What is Time Complexity? Time Complexity tells us: How much time an algorithm takes to...

How to Get Real-Time Traffic Camera Feeds via API

No major traffic data provider gives you camera feeds. Not HERE, not TomTom, not Google, not INRIX. They all sell traffic flow from probe data, but live camera images? Nobody aggregates that. Road511 does. 10,000+ traffic cameras across 40+ US states and Canadian provinces, all accessible through one REST API. The Problem Every state DOT publishes camera images, but every one does it ...

GraphQL in Go looks simple at first: write a schema, run gqlgen, fill in the resolvers. But the real story starts later.

GraphQL in Go looks simple at first: write a schema, run gqlgen, fill in the resolvers. But the real story starts later.

Once the project grows, schema design, resolver boundaries, custom scalars, and generated code layout start shaping the whole architecture. gqlgen is not just a code generator — it quickly becomes part of how your API lives and evolves. In this post, I break down what actually matters when using gqlgen in real Go projects: structure, thin resolvers, cleaner schemas, field-level control, and mai...

Alfred lives between my inbox, my calendar, my DevOps boards, Teams, and even my robot vacuum. That article walked through how I stitched all those tools together into one agent that actually does things for me instead of just talking about them. If you have not read it, this...

I turned 23 Vanta RED tests GREEN in 14 days. Here is the exact command for each one.

The problem Vanta does not solve Vanta is excellent at telling you what is wrong. The dashboard is beautiful. The RED tests are clear. The remediation instructions are detailed. But Vanta does not fix anything. Every RED test represents a gap between the compliance requirement and your current infrastructure. Closing that gap requires someone to write a Kubernetes network policy, modif...

Author here. Yojam replaces the default browser on macOS so every URL - clicks, Finder .webloc/.inetloc/.url files, Handoff, AirDrop, Share and Services menus, Safari/Chromium/Firefox extensions, and a yojam:// scheme - runs through one pipeline: global regex rewrites, tracking-parameter scrubbing, rule matching, per-browser rewrites, then open-or-pick. Technically interesting bits if you want to ...
