Migration of YouTube from SQL to NoSQL: A Component-Wise Analysis

Introduction Initially, large-scale platforms like YouTube relied on traditional Relational Database Management Systems (RDBMS) such as MySQL.

Can AI Review Physics? Yes — That Is Why We Built SPAR

A standalone review framework for checking whether outputs deserve the claims attached to them. Most review systems answer a familiar question: Did the system still produce the expected output? SPAR is built for a narrower and more dangerous one: Does the output still deserve the claim attached to it? That is the split. Not reliability alone, but admissibility. In practical terms, admissib...

This article proposes a five-dimension evaluation framework and a structured cognitive assessment battery designed specifically for persistent AI per...

Getting Leap Years Right, and Listing All 27 Leap Seconds Ever Inserted

Getting Leap Years Right, and Listing All 27 Leap Seconds Ever Inserted "Every four years" is the leap year rule most developers remember. It's wrong on century boundaries. 1900 was not a leap year, 2000 was, 2100 won't be. Writing a tiny tool to check this led me to a nearby rabbit hole: leap seconds — a completely separate concept, and a historical curiosity with exactly 27 entries. ...

Resident Evil Star Milla Jovovich Shipped an AI Memory System. Devs Shredded Its Benchmarks

Actress Milla Jovovich and crypto CEO Ben Sigman shipped an open-source AI memory system called MemPalace. It went massively viral with 1.5 million impressions, 36,800 stars, on the back of claims like "first perfect score ever recorded" on LongMemEval. Within hours, developers tore the benchmarks apart.

Writing a Hepburn Hiragana ↔ Katakana ↔ Rōmaji Converter (With All The Annoying Edge Cases) "Sanpo" or "sampo"? "Matcha" or "maccha"? Hepburn romanization has rules that naive 1:1 mapping gets wrong, and those are exactly the rules that appear on road signs and passports. I wrote a converter that handles them properly.

Building an AI-Assisted React Native UI Kit — Why Tokens Beat Pixels in the Age of Copilot

We're in an era where developers write UI with AI. You describe a screen, Claude or Copilot generates the code, and you ship it. But there's a gap nobody talks about: AI-generated UI is inconsistent. Ask it to build a login screen — it picks padding: 16. Ask it to build a settings screen — it picks padding: 20. Ask it for a card — borderRadius: 8. Another card — borderRadius: 12.
