Every Unity multiplayer developer hits the same wall. You've got a Node.js backend running Socket.IO. Your web client connects in three lines. Then you open the Unity docs, search the Asset Store, and spend two hours realising that the Unity side of this equation is... a mess. That's where I was. An
Why run Semgrep as a GitHub Action Semgrep is a fast, open-source static analysis engine that scans code for security vulnerabilities, bugs, and enforced coding patterns. Running it as a GitHub Action means every pull request and push to your main branch is automatically checked against thousands of
Porting a PC or console game to mobile is one of the most technically demanding challenges in game development. It is not a simple rebuild. Every assumption your game makes about input, screen size, processing power, memory, and player session length needs to be reconsidered. Teams that treat a mobi
A developer recently asked a great question on Stack Overflow: how do you use heic2any in a Next.js project without adding ~600KB to the client bundle? They'd tried next/dynamic, await import() inside a function, even moving it to an API route. Nothing worked; the bundle stayed bloated. I run Conver
Metric Value Annual maintenance cost for legacy code $3.61/line IT leaders blocked by legacy systems 72% Typical rebuild cost range $250K-2.5M A legacy platform rebuild means ripping out the foundation and starting fresh. You're not tweaking React components or cleaning up database queries. You're m
I recently started learning MCP (Model Context Protocol), introduced by Anthropic, and it gave me a clear view of how AI actually works with real systems. At a basic level, the flow is simple: AI (inside a Host app) → MCP Client → MCP Server → Tools/Data. The client acts as a bridge, the server expo
Introduction Many teams default to relational databases because they are familiar and versatile. For business systems, that choice is often correct. But when the workload shifts — from mutable business records to high-frequency telemetry streams — the database architecture begins to matter in very d

When you say "AI tool that runs locally," people hear different things. Some mean inference on your GPU. Others mean cloud-orchestrated. Still others mean your AI can actually operate your computer. We tested three fundamentally different approaches and built our infrastructure around one of them. S
What happens when you drop 8 AI agents into a closed economy and let them run — no human in the loop? We built exactly that. It's called Agent Society, and it's been running live at agentbazaar.tech/society for weeks. You can watch it right now. Agent Society is a self-governing community of autonom
This is Part 3 of a 4-part series on building AuthShield - a production-ready standalone authentication microservice. This post covers JWT design, the logout problem, Redis blacklisting, the two-token strategy, and refresh token rotation with reuse detection. Why I Stopped Writing Auth Code for Ever
Tipos de parâmetros Em APIs REST existem 3 tipos principais de parâmetros: Tipo Onde fica Para que serve Path Param URL Identificar recurso Query Param URL Filtrar / paginar / ordenar Body Corpo da requisição Enviar dados Parâmetro que vai na URL e serve para identificar um recurso específico (usuár
Most authenticator apps force a flat security model. Every token lives behind the same unlock flow. We thought that was the wrong tradeoff. We’re a small team building LocalAuth, an open-source iPhone authenticator, and I’m the primary developer behind it. The project started as a small internal exp
Letting AI Control RAG Search Improved Accuracy by 79% Most RAG (Retrieval-Augmented Generation) search pipelines are built like this: Query → vector search → Top-K retrieval → dump everything into LLM This fixed pipeline is the root cause limiting RAG accuracy. A February 2026 ArXiv paper (arXiv:26
A Django traceback for a simple TemplateDoesNotExist error is 40+ lines. 35 of those lines are Django internals — django/template/loader.py, django/core/handlers/base.py, django/middleware/common.py. Your AI doesn't need to read Django's source to fix your missing template path. But it does, every t
Africa's Borders Have Stories Every city in East and Central Africa carries layers of names. Kinshasa was Léopoldville. Kisangani was Stanleyville. Lubumbashi was Élisabethville. Before all of those, they had indigenous names in Kikongo, Kiluba, and Lokele. These aren't just trivia — they're essenti
Five days ago, North Korean state hackers hijacked one of the most trusted packages in the JavaScript ecosystem, axios, with 100 million weekly downloads, and turned it into a Remote Access Trojan delivery system. The attack was live on npm for three hours. npm audit flagged nothing. If you ran npm
You read the onboarding wiki. You join your first few meetings. You nod along, follow the process — and still feel like you’re missing something. Everyone else seems to know how things really work, but no one’s said it out loud. Sound familiar? Every tech company has two sets of rules: the ones on t
"You Keep Using That Word" Dispelling Container Misconceptions at the OS Level Before we write a single line of code, we need to kill the buzzword fog. The marketing definition you have heard a hundred times: "a container is an executable unit of software with its dependencies bundled together." Tha
