Why Data Quality is Becoming More Important Than Model Size in Modern AI Systems

For years, progress in artificial intelligence was closely tied to scaling laws, where increasing model size, dataset size, and compute power led to consistent performance improvements. Large-scale systems like GPT-4 and architectures such as Transformer architecture demonstrated that bigger models could achieve remarkable capabilities across language, vision, and multimodal tasks. However, recent...

Debugging HTTP Requests in ASP.NET Core Across Environments

When the same HTTP request works in dev but fails in production, debugging gets messy fast. Example: a request returns 200 in dev but 400 in prod because of a missing header or slightly different payload—and it’s not obvious why. Most of the time, this means jumping between logs, Postman, and custom middleware, trying to spot the difference. To simplify this, I started working on a lightweight ...

“How I Started Learning MERN + AWS as a Beginner (No Experience)”

From Confusion to Clarity: My First Steps into MERN + AWS When I first decided to learn web development, everything looked simple… until I actually started building something I began with the MERN stack (MongoDB, Express, React, Node.js), thinking I’d quickly create a few projects. But reality hit when I tried to connect frontend with backend for the first time. What actually challenged me: U...

Self-hosted blockchain node: challenges and solutions

Running a self-hosted blockchain node — one that validates transactions and provides blockchain data to dapps, wallets, and exchanges — is a key way to participate in and help secure a decentralized network. But the real challenges emerge after deployment, not during setup. Ethereum founder Vitalik Buterin acknowledged the problem directly: managing a node has quietly become a complex DevOps ta...

AI Coding Agents Just Escaped The IDE: Codex, Gemini CLI, And The New Terminal Gold Rush

Developers used to meet AI inside the IDE, get a suggestion, accept it, move on. That model is already getting old. The new fight is happening in the terminal, where coding agents can read repos, run commands, inspect logs, patch files, and keep moving without waiting on every tiny click. Codex, Gemini CLI, and tools like Claude Code are pushing AI from autocomplete into real workflow control. T...

A2A: the boring NEXT '26 announcement I can't stop thinking about

This is a submission for the Google Cloud NEXT Writing Challenge Hey folks, welcome back!! So here's the thing. For the last few weeks, I'd been quietly stuck on a problem that sounds embarrassingly simple. I have a few AI agents I've been playing around with. One does research. One drafts content. One reviews stuff. And in my head, the obvious next step was... get them to talk to each other. Pa...

Realizing I’m better at connecting dots than finding problems - where does this fit in engineering?

I have ~12 YOE and have operated as a Staff Engineer at a mid-size org, and more recently at a startup (which didn’t work out). The expectations there felt borderline 'superhuman' for a senior IC which has been mentally taxing and exhausting, which pushed me to reflect more deeply on my strengths and gaps. One pattern I’ve noticed: I’m not very strong at independently finding problems through deep...

Anyone else avoiding online converters for privacy?

Lately I've been trying to avoid online image converters, especially for stuff like HEIC/AVIF or batch resizing. Not even saying they're bad — they're superconvenient — but uploading a bunch of images (sometimes personal or work-related) just feels a bit off. Plus I've noticed some of them compress weirdly or take forever with larger batches. I ended up trying a couple of offline tools instead, in...

In just months, Model Context Protocol went from a niche idea to a real topic in AI product meetings, dev Slack threads, and roadmap docs. Why? Because developers are tired of wiring every model to every tool in a custom way. MCP offers a cleaner path. It gives AI apps one standard way to connect with tools, data, and action...
