When I built UltrafastSecp256k1 — a high-performance secp256k1 cryptography library targeting CPU, CUDA, OpenCL, Metal, ESP32, and a dozen other platforms — I faced a decision every serious crypto library author eventually faces. "You need a third-party audit." The quotes I got: $80K–$120K. Two week

A common theme in those sessions is the need for better cost visibility. Teams are moving fast with AI, but as they go from experimenting to fu
This is a submission for the DEV April Fools Challenge DEFINITELY NOT A TROLL GAME™ — a platformer that looks completely normal but systematically betrays every gaming instinct you've ever developed.

The $15 Per Ride You Didn't Know About: What 243 Million NYC Taxi Rides Reveal Lyft pays wheelchair-accessible drivers 204% of fare — a flat ~$15/ride bonus regardless of trip distance. Uber pays 101%. Same city, same mandate, completely different economics. 243 million high-volume for-hire vehicle
Building Adaptive Learning Systems: Lessons from Sikho.ai Over the past year we have been building Sikho.ai — an AI-native learning platform that adapts in real time to each learner. Along the way we picked up some hard-won lessons about what adaptive systems actually require in production. This pos
Why I Built My Own AI Tutor (and What I Learned) Most devs have built a side project chat wrapper around OpenAI or Anthropic. Few have tried to turn one into a real learning tool. This post is about what changes when you do — and what I learned building Sikho.ai. Hooking a model into a UI takes an a
“There are only two hard things in computer science: cache invalidation and naming things.” It’s been about a year since I started using AI daily. In my core role as an SRE/DevOps engineer, AI behaves like a very fast and very obedient assistant. It helps me collect data across services via MCP, gen
Software Development Life Cycle : SDLC (Software Development Life Cycle) model is a structured, step-by-step framework that defines how software is planned, designed, built, tested, and deployed to ensure high quality and efficiency. It breaks development into phases—typically planning, analysis, de

GitHub: https://github.com/Mininglamp-AI/Mano-P Mano-P is a pure-vision GUI agent. It looks at your screen — literally a screenshot — understands the UI e
Modern observability—think Grafana, Datadog, New Relic, and similar stacks—gives you deep insight: traces, service maps, golden signals, and often real-user monitoring. That raises a fair question: if telemetry is everywhere, why run uptime checks and synthetic monitors? They answer different questi

What Instagram actually does to your photos Every photo you upload to Instagram gets re-compressed. There are no exceptions. Instagram takes your file, resizes it if needed, re-encodes it as JPEG, and stores a much smaller version. The original is gone. How aggressive is this compression? Tests show
