I find Japan-shaped holes in global software

There's a category of bug that only exists if you type Japanese, and it keeps showing up in software built by people who don't. Same shape, different repo, over and over. After a while you stop being surprised and start being able to guess which file it's in before you open the project. The one I hit most: you're typing into a search box, the IME pops up conversion candidates, you press Enter to pick the right kanji, and instead of confirming the word the app runs the search on half-finished tex

KV Cache Is Eating Your VRAM — Here's How to Estimate It Before You Run Out

Every LLM inference engineer hits this wall eventually. You deployed a model, it works in testing, then production traffic arrives. Suddenly your 80GB A100 is OOM on a 70B model that "should fit." The culprit is almost always the KV Cache. But most discussions stop at "it caches the Key and Value matrices" — which doesn't help you predict when you'll run out of memory. This post gives you a quick estimator formula, explains when to worry, and what levers actually help. Here's the quick estimator

7 AI Prompts That Save Me 10+ Hours Every Week as a Developer (Copy-Paste Ready)

I tracked every AI prompt I used for 30 days straight. Most were throwaway. But seven of them came back over and over — and together they save me at least 10 hours a week. These aren't "act as a senior developer" fluff. They're specific, structured prompts with slots you fill in. Copy them, paste them, edit the [bracketed] parts. Let's go. We all inherit code we didn't write. Instead of tracing through 300 lines line-by-line: Explain what this code does, step by step. Focus on: 1. The overall pu

WHOIS Is Broken in 2026. Here's the RDAP-First Drop-In That Actually Returns JSON

WHOIS has been quietly dying for a decade, and most teams only noticed in the last eighteen months. If you ran a domain-intelligence pipeline between 2015 and 2022, the story went like this. You shelled out to the whois binary, or hit a free public wrapper, or paid WhoisXML API $0.00099 per lookup. You wrote a parser full of regex special cases for Verisign vs. Afilias vs. Nominet vs. DENIC, caught the edge cases where .jp returned Shift-JIS, normalized the date formats, and shipped. It worked,

AIKit Launch Metrics Dashboard: Product Demo Signals That Turn Blog Traffic Into Funnel Decisions

Short answer: a launch metrics dashboard turns every blog post, demo page, and CTA into a product decision system. Instead of asking whether content feels successful, AIKit teams can inspect traffic quality, CTA intent, and trial conversion signals in one launch cockpit. Most product launches fail quietly because the team measures the wrong layer of the funnel. Page views tell you whether distribution worked, but they do not explain whether visitors understood the demo, trusted the promise, clic

Why End-to-End Encryption is a Lie (And How I Weaponized Golang to Fix It)

The cybersecurity industry is playing a rigged game. We obsess over End-to-End Encryption (E2EE), but the moment your payload hits the RAM of a cloud provider (AWS, Azure, GCP), you are at the mercy of their hypervisor. A single memory snapshot compromises your entire routing architecture. You don't own your cryptographic keys. The hypervisor does. Standard architectures build walls. I decided to build a self-destructing maze. Enter TITAN NEXUS. Confidential Computing (SGX/SEV) is a band-aid.
