How to Choose the Best Crypto Exchange for Bot Trading in 2026

Your trading strategy can be flawless. Your risk management can be textbook. But if you deploy your bot on the wrong exchange, none of it matters. The exchange you choose determines your execution speed, trading costs, uptime reliability, and ultimately — your profitability. In 2026, the exchange landscape has matured significantly. API infrastructure has improved across the board, but meaningful...

Stop Managing Browser Sessions Yourself. Use Steel and Convex

Most browser automation setups work fine until they don't. You get Puppeteer running locally. It works. You ship it. Then a server restarts mid-session, a user's data gets lost, and you realize you have no idea which sessions belong to which users or what state they're in. This is not a Puppeteer problem. It's a missing infrastructure problem. Browser sessions are stateful. They have owners. Th...

How I replaced 200 lines of Zod refinements with 12

Every project I start ends up with the same validation code. Email with disposable domain blocking. Password with strength rules. Phone number via libphonenumber-js. Username with reserved word checks. All built with .refine() and .superRefine() chains on top of Zod. Different projects, different defaults, forgotten edge cases. The same bugs are showing up in different codebases because I copied...

Is it just me, or is finding an AI tool that actually works becoming impossible?

I’ve spent the last week trying to find a decent AI video editor that doesn't require a $50/month subscription or a 20-page "Ultimate Guide" to understand. Every Google search is just SEO spam and sites full of pop-ups. I finally stumbled on a directory that’s actually clean and doesn't feel like it's trying to sell me something every 5 seconds. I actually found a tool called Kling AI (o...

retry-pro vs p-retry: Best Node.js Retry Library for Async Functions (2026)

Deep Dive: Securing P2P Crypto Exchanges Against 2026 Attack Vectors (with Code)

Building a secure P2P platform in 2026 is no longer about simple CRUD operations. As a developer at ProfitScripts Asia, I've analyzed dozens of "ready-made" scripts that fail under modern stress tests. Here is a technical breakdown of 3 critical vulnerabilities and how to patch them. The "Fake Confirmation" Trap (Atomic Validation) Many scripts rely on a single RPC node or, worse, a frontend-si...

Rethinking Web Sessions in Distributed Web Architecture

Web sessions have been a fundamental part of web applications for decades. They help systems remember users, maintain authentication, and track interactions across requests. For a long time, this traditional session model worked well because web applications were simple, centralized, and mostly tied to a single server. Today, web applications operate in a completely different environment. Modern...

Why I Built a 4,000-Line Agent Skill Instead of Another npm Package

The Problem I use Claude Code (and sometimes Cursor) for frontend work every day. And every day, I fix the same mistakes: // AI generates this const user: User = await res.json() Looks fine. TypeScript is happy. But res.json() returns any at runtime — if the API changes shape, this silently breaks in production. // AI also loves this const [isLoading, setIsLoading] = useStat...

Why creating an AWS account is harder than it should be — especially in India

You decided to learn AWS. You went to aws.amazon.com, clicked "Create a Free Account," and ran straight into a wall. Credit card required. Phone verification that never calls back. A mysterious ₹2 charge on your card. Documents that don't match. An account suspended before you ever deployed anything. This is one of the most complained-about onboarding experiences in cloud computing — and if you ...

Introduction to Embedded Linux

Context Most developers are familiar with software that runs on laptops, servers, browsers, or mobile phones. But there is another world where software does not run in isolation. It runs on devices that interact with the physical world — routers, gateways, industrial controllers, cameras, infotainment systems, and many other smart devices. That world is where embedded Linux comes in. ...
