Claude Code accounts switcher, Finally!!

Picture this. You've spent time getting Claude Code just right — your skills configured, plugins loaded, MCP servers humming. It feels good. You're productive. Then you switch accounts. Gone. All of it. I have a personal Claude account and a work one. Every switch meant re-authenticating through the browser AND rebuilding my entire setup. It happened enough times that I stopped switchi...

Building AI-Verified APIs on the Blockchain: A Practical Guide to GenLayer

Imagine a smart contract that reads a news article, decides whether a prediction market resolves in your favor, and records that verdict on-chain — without trusting any third party to feed it the data. No oracle. No intermediary. The contract itself fetches the page, reasons about it, and commits the result. That's not a concept. That's GenLayer, and it's running on testnet right now. This ...

(EDA Part-3) Univariate Analysis — Understanding Every Feature One at a Time

Part 3 of 5 — Intermediate In Part 2, we got the patient's file open. Now, it is the time for the real examination. We're going to look at each "organ"—each feature in our dataset — one by one. This is called univariate analysis, which is just a fancy term for looking at one variable at a time. We are not trying to find relationships yet. We are just getting a feel for the landscape. What doe...

A declarative CLI framework in Rust

I built a declarative CLI framework in Rust (define your CLI in TOML) Most Rust CLI tools are built with libraries like clap. They’re powerful—but also verbose. After building a few internal tools, I kept running into the same problem: Too much boilerplate for simple commands Repeating argument parsing logic Hard to manage growing CLI complexity So I built tkucli — a declarative CLI frame...
