Vibe Coding Is Dead. Here's What You Actually Need to Pass Technical Interviews in 2026.

Andrej Karpathy coined "vibe coding" in early 2025. By February 2026, he declared it passe. The replacement? Agentic engineering, where AI agents don't just autocomplete your code. They autonomously plan tasks, read your codebase, run tests, and self-correct. And this shift is completely changing how companies hire. I've been building ByteMentor AI, an interview prep platform with 19 AI-powered...

Why I Over-Engineered a ULID Library for .NET

Unique identifiers are often treated as an afterthought, but for senior engineers and architects, they represent a critical choice in system design. "Good enough" identifiers are a ticking time bomb of index fragmentation and degraded performance. Why ULID over UUIDv7? While UUIDv7 is a step forward, its specification makes monotonicity optional. During high-concurrency bursts, many ge...

Designing Errors Out of Your Go CLI

Most Go CLIs have too many error checks. Not because error handling is wrong — because the errors themselves are wrong. I read the Power of Go Tools by John Arundel. Based on his book, I audited a 50,000-line Go CLI for functions that return errors unnecessarily. The result: 10 functions refactored, 50+ if err != nil checks eliminated, and the remaining error checks now mean something. This is J...

When custom WordPress development actually makes sense (and when it doesn’t)

I’ve reviewed dozens of WordPress projects where the client asked for a “custom rebuild” and the real fix was simpler. Small changes in structure, fewer plugins, or a clearer content strategy often solve 80% of the pain. One useful rule of thumb Think of custom development as an investment to solve constraints that are structural, not aesthetic. If the problem is about processes, integ...

NexusQuant vs KVTC vs TurboQuant vs CommVQ — honest comparison

There are now enough KV cache compression papers that "we beat the competition" is meaningless without specifics. Which competition? On which data? At which compression ratio? With or without calibration? This post is an honest head-to-head. For each competitor: what they do, their reported numbers from their papers, our numbers, where we win, and where they win. The comparison table...

I Turned Notion Into a Shared Brain for AI Agents (and it actually made sense)

The thing that bugged me Every "AI + Notion" demo I've seen does roughly the same thing: you prompt a model, it generates text, the text gets dumped into a Notion page. Done. It works. It's fine. But it's basically a fancy copy-paste. The agent writes to Notion, but Notion doesn't do anything. It's a filing cabinet, not a workspace. And that felt like a waste. Because Notion already ...

I Thought Normalized State Would Fix My Re-render Problem. It Didn't.

I Thought Normalized State Would Fix My Re-render Problem. It Didn't.

I was building a Kanban board called Kantoo and hit a classic React performance problem. This is what I tried, what didn't work, and what actually fixed it. What I Built First I went with a normalized state architecture managed through useReducer. The idea was simple: instead of deeply nested state, keep everything flat. Each column and card lives in its own lookup object, and you refe...

Build the System, Not the Prompt

If I had to roll out AI again, I wouldn't change the tools. I'd change the approach. I'd start with one repeatable workflow, map every step, define what good output looks like, encode it once, and turn the whole thing into a pipeline. Then I'd improve the system instead of rewriting prompts. That framework didn't come from reading about AI adoption. It came from getting it wrong first and then bui...

Common Red Flags in Fake E-commerce Sites

The way detection algorithms decode the signals is by distinguishing between a scam storefront and a real one. A security researcher by the name of Priya was conducting a honeypot experiment in November 2024. She had created a purposely non-authentic e-commerce store with stolen product images, a copied checkout process, and a new domain, registered a few hours earlier, with a single letter change...

TypeScript's Type System: Beyond the Basics for Robust Applications

Why Your TypeScript Types Might Not Be Safe Enough You've adopted TypeScript. Your any types are (mostly) gone, and you get those satisfying green squiggles in your editor. But have you ever pushed a change, confident in your types, only to face a runtime error that TypeScript swore couldn't happen? You're not alone. Many developers hit a plateau where basic interfaces and string | numb...

Beyond the Event Loop: Tracking Slow I/O in Production Node.js

Your Node.js service is slow. You run a profiler. CPU usage is low. The event loop isn't blocked. Everything looks healthy. But users are still waiting 3 seconds for a response. This is the blind spot that most Node.js diagnostic tools have. They focus on what's blocking the event loop — CPU-bound work, synchronous I/O, regex backtracking. But in modern Node.js applications, the most common perf...

Trunk-Based Development: Why Most Teams Think They Use It (But Don’t)

Trunk-Based Development sounds simple. No long-lived branches. Frequent merges. Small, incremental changes. Most teams will tell you: “Yeah, we basically do trunk-based development.” In practice, they don’t. What they usually have is a hybrid that keeps the downsides of feature branches — while pretending to get the benefits of trunk-based development. I’ve seen this pattern in multiple ba...
