My First Look at NFTs on Solana

When I first heard about NFTs, I assumed they were just randomly generated JPEG collections—mostly apes and profile pictures that became valuable because of hype. After building one on Solana, I realized an NFT is much more than an image. It's simply a token with a unique set of rules. Coming from a Web2 background, my biggest question was: What actually makes an NFT an NFT? I expected there to be a special NFT object. Instead, I learned that on Solana, an NFT is just a token configured with the

Your README Is More Than Documentation

TL;DR: Your README isn't just documentation. It's your project's first user experience. A clear README helps people understand, trust, and start using your project faster. A few years ago, I thought a good project would naturally attract users if the code was solid enough. One of the turning points for me came while contributing to an open-source Python-based project. The project itself was genuinely impressive, with a well-designed codebase and useful API functionality. But when I looked at the

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,
