Deconstructing NYTimes Video Streaming: Building a High-Performance Extraction Engine with HLS and FFmpeg

Introduction As developers, we are often fascinated by how global-scale platforms manage and distribute multimedia data. The New York Times (NYTimes), a premier global news organization, utilizes a sophisticated distribution architecture that isn't just simple file hosting, but a complex system based on HLS (HTTP Live Streaming) for dynamic adaptive delivery. For researchers, journalist...

I Almost Burned Out. Then I Built Systems Instead.

The Problem Isn't You. It's the Architecture. By early 2026, I was running three projects simultaneously, answering Slack messages at 11pm, and telling myself the chaos was temporary. It wasn't. According to McKinsey's research on burnout and resignations, employees who experience burnout are 2.3 times more likely to leave their jobs—and the root cause isn't weak character, it's unsusta...

Natives vs Boxing Wrappers in JavaScript

In JavaScript, you work with primitive values (like strings, numbers) but still call methods on them. That's possible because of boxing (wrapper objects). 🎯 1. What are Natives?

Sixty Seconds Every Morning Is More Than You Think

Rohan had a big client call at 11 AM. He'd rehearsed his pitch the night before, felt good, slept okay. Then the call started and his first sentence came out thin and rushed, like he was already apologizing for being on the line. He told me later: "Bhai, the words were right. But my voice was still asleep." His voice was still asleep. That phrase stuck with me because it's so accurate and nobody...

Why status page aggregators matter for engineering teams

Why status page aggregators matter for engineering teams

Every serious product leans on a handful of clouds, data stores, identity providers, payment rails, and edge networks. In practice, a typical engineering team depends on more than five cloud vendors, SaaS tools, and managed services—often many more—and each publishes its own status surface. Those pages are often well designed but rarely aligned with one another. The gap is not whether they exist; ...

How a WooCommerce Agency Ships Checkout Fields Without Late-Night Panic

The support ticket arrived at 11:47 PM: 'The gift message field is missing on live, but it's there in staging. Black Friday starts in six hours.' For the third time this month, the agency's WooCommerce specialist had to manually recreate 17 custom checkout fields, conditionally required for corporate gifts, hidden for wholesale accounts, by toggling admin panels on production while cross-referenci...

Origin Part 2: Nobody Told It Harm Was Bad

OLT-1 was never trained to refuse harmful requests. It refused anyway. Most AI safety works like this: train a massive model on everything the internet has to offer, then fine-tune it to refuse harmful requests. The model doesn't understand why it's refusing. It just learned that certain patterns of words trigger certain patterns of rejection. That's alignment through obedience. It works, until ...

Attention Mechanisms: Stop Compressing, Start Looking Back

"The art of being wise is the art of knowing what to overlook." — William James The Bottleneck We Didn't Notice In my last post, we gave networks memory. An LSTM reads a sentence word by word, maintaining a hidden state that carries context forward. It solved the forgetting problem that plagued vanilla RNNs. But there are three problems LSTM still doesn't solve. And I didn't fully un...

Figma has been the unchallenged design layer for product teams for years. On April 17, 2026, Anthropic quietly placed a bet that the next design tool doesn't look like Figma at all — it looks like a conversation. The Problem It's Solving Design has always had a bottleneck that nobody talks about openly: the distance between the person with the idea and the person who can execute it. A ...

Structure-Driven Engineering Organization Theory #6 — Designing Interventions (1-on-1 / Pair Programming)

Six months of weekly "how are things going?" 1-on-1s won't move the organization one millimeter — the intervention is trapped at the behavior layer. The moment the conversation opens that way, it doesn't touch accumulation by a single gram. Cut with structure, not with emotion. That's the only intervention that moves organizations. Scope of this chapter: design layer (decomposing interventio...

The Personal Small Model (PSM): Memory as a Learned Cognitive Primitive

The Problem With Every Memory System Today mem0, Zep, Letta, MemPalace — they all make the same foundational assumption: Memory is a storage problem. Build a good enough database. Implement a smart enough retrieval mechanism. Inject the results into the LLM’s context. The model consumes the fragments. The model forgets. The cycle repeats.

The Difference Between Burnout and Being Tired

Tiredness goes away after a good night's sleep. Burnout doesn't. Here's how to tell them apart — and why getting it wrong costs you months. Most engineers who are burning out don't know it yet. They think they're just tired. They think a long weekend will fix it. They take Friday off, sleep in, do nothing — and come back Monday feeling exactly the same. That's the moment it becomes worth asking: ...

Is Railway a Good Fit for Agencies in 2026?

You can absolutely use Railway to ship client work fast. The harder question is whether you should make it your agency’s default production platform. For most agencies in 2026, the answer is no. Railway still makes a strong first impression. The setup is fast, the dashboard is clean, and the path from repo to live URL is genuinely smooth through its quick start, GitHub deploy flow, and built-in ...
