We Hit 99.1% on the LOCOMO Benchmark. Here's How.

We Hit 99.1% on the LOCOMO Benchmark. Here's How. Last week, we hit 99.1% accuracy on the LOCOMO benchmark. For context: Mem0: 26% Engram: 79.6% Muninn: 99.1% That's a 73-point gap over Mem0. A 20-point gap over Engram. The breakthrough wasn't a new model or complex architecture. It was removing a single assumption. What is the LOCOMO Benchmark? LOCOMO (Long-Cont...

JSON vs JSONB in PostgreSQL: I tested 1M rows to find ou

Recently I tried to resolve a recurring question in our team: Is JSON or JSONB actually faster in PostgreSQL? I couldn’t find a clear answer that matched real-world usage, so I ran my own benchmark. Setup I loaded 1 million records with identical data into both JSON and JSONB columns and tested common operations. Hardware: Dell PowerEdge R450 2x Intel Xeon Silver 4310 (24/48 core...

A Searchable HTTP Status Code Reference with 36 Codes, One-Line Descriptions, and Yes, 418

A Searchable HTTP Status Code Reference with 36 Codes, One-Line Descriptions, and Yes, 418 Is 401 or 403 the "not authenticated" one? Which RFC defines 418? What even is 226? I kept leaving my editor to look these up and decided to build a single-page reference I could actually keep open in a tab. Vanilla JS, 36 codes, one-line descriptions, search on code / name / keyword. Every dev...

Why 1100 / 1.1 = 999.9999… Is a Tax Calculator Bug, and Two Ways to Fix It

Why 1100 / 1.1 = 999.9999… Is a Tax Calculator Bug, and Two Ways to Fix It Japan has a 10% consumption tax (8% for groceries and newspapers). Your naive JavaScript calculator goes 1100 / 1.1 → 999.9999999999999 → Math.floor → 999 and produces a tax receipt that's off by one yen, which is the kind of thing you cannot ship. I hit the same bug writing a tax calculator for Japanese prices,...

Every few months, a new blog post makes the rounds arguing that Company X achieved a 40 percent performance improvement by switching from Framework Y to Framework Z. The comments fill up with developers debating whether the migration was worth it, what the team should have chosen in the first place, and which emerging technology will make both options obsolete by next year. Meanwhile, the teams th...

Architecture patterns are not academic exercises. They are practical solutions to problems that every web application encounters at some point: how to organize code so multiple developers can work without stepping on each other, how to scale specific parts of the system without rewriting everything, and how to keep the application maintainable as features pile up over months and years.

How We Ran Two Portals on the Same Domain During a React Migration (Without Users Noticing)

You missed a critical feature, or worse — the new app can't handle production traffic and crashes under load. That thought kept me up. So we didn't do a big bang cutover. We kept both portals running at the same time - here's how Instead, I pushed for a canary-based rollout — keep both portals runnin...
