You Just Want to Test Two Buttons You're a developer at a Series A startup. Your product manager walks over and says: "We need to A/B test the signup flow. Three variants, maybe four. Can you set that up this week?" Simp
I have a long-running series of daily web dev diary on LinkedIn, but I decided to move it to a more developer-related community, so here is how my day of learning went! I'm continuing to dive deeper into React, and today
The large language model space is moving fast, but one trend is quietly defining the next phase of AI: inference optimization. While headlines focus on bigger models and benchmark wins, the real innovation is happening b
How I Built It: The "Boss-Agent" Workflow My development process was a study in AI orchestration. I operated at a "Boss-Agent" level, managing two distinct AI entities to take Moonbud from a mobile concept to a live depl

Every developer has been there: you paste an error into Google, find a Stack Overflow answer from 2014, and still have no idea what actually went wrong. I built Debuggle because I was that developer — and I still am, hon

I've been building an Android app that overlays aircraft labels on a live camera feed when you point your phone at the sky. You fetch a plane's position from an ADS-B API, you have your own GPS location, and the goal is
I have an idea. As serious and professional developers of serious and professional things, we have all encountered the standard, boilerplatey documents in serious and professional projects. Such files include, but are no
Ferramentas de IA como o GitHub Copilot mudaram completamente a forma como desenvolvemos software em .NET. Elas aceleram tarefas repetitivas, sugerem soluções e podem gerar blocos inteiros de código em segundos. Mas há u
I needed digital business cards for a small team. Should be simple, right? I spent way too long looking at existing tools before I snapped and just built my own. Here's why. The problem Every tool I tried had at least on
Claude Design Is Here — AI Is Entering the Visual Creation Era Anthropic has introduced Claude Design, a research preview tool that goes far beyond traditional AI chat. It turns ideas into polished prototypes, presentati
Closures aren't magic, but for two years, I genuinely thought they were dark sorcery. If you've ever felt utterly baffled by how a function remembers variables from its parent scope long after the parent has returned, yo
There's a structural weakness in almost every app built in the last decade and we don't talk about it much because we're all doing it. The app requires our infrastructure to function. The moment we stop paying the server

🚀 I Built an AI Agent That Writes Viral LinkedIn Posts in My Voice Most AI writing tools sound the same. Same hooks. Same tone. Same “AI feel.” So I built LinkedIn Post Pilot — an AI system that: Writes LinkedIn posts i
The idea is simple — just create universal [...path] folder and proxy everything through it specifying patterns in some urls.ts . So, we have to create minimal and universal +page.js and +page.server.js with load functio
A2A Agent Cards describe what an agent can do, where it lives, and how to talk to it. What they do not describe is governance posture. Two agents can hold identical cards and behave nothing alike in production. We shippe
DocuSign pioneered the e-signature category, but in 2026 the landscape looks very different. Teams evaluating e-signature tools have dozens of options, each optimized for different use cases — embedded signing for SaaS a
I work in an Azure-focused systems and cloud administration role, so GitHub Actions was already part of my day-to-day life before I decided to take GH-200. I was not walking in as a beginner. I had already written workfl

Every website owner has faced this "invisible" performance killer: You push a fresh update, clear your server cache, and suddenly your site feels sluggish. For that first visitor, the experience is frustratingly slow. Th
Since Karpathy coined the term vibe coding , some of my non-coding friends have been showing me their work and teasing me that they can now do everything I can. Anthropic just dropped Claude Design . Now it's my turn. Sh

The Solana ecosystem moves incredibly fast. With block times sitting around 400 milliseconds, anyone building automated workflows, indexing tools, or real-time analytics dashboards runs into one major challenge: RPC reli
Stell dir vor, du bezahlst für ein Modell das viermal so oft falsch liegt und vierzehn mal so viel kostet wie das Standardmodell. Das klingt absurd. Und es ist passiert: In einer Evaluation von splx.ai aus 2025, die o3-p
