Turn Chatbot Misunderstandings Into Grammar Regression Tests

A custom-grammar bot can be reliable right up until someone types a perfectly reasonable sentence that the grammar author did not anticipate. The uncomfortable choice is usually framed as either: keep the grammar deterministic but frustratingly narrow, or let an AI model interpret everything and accept less predictable behavior. That is the wrong boundary. You can keep command execution deter...

I Built an AI Name Generator Because Naming Is Harder Than It Looks

Naming things is one of those problems that looks simple until you actually have to do it. A startup founder needs a product name. A developer needs a project name. A writer needs character names. A new pet owner needs a name. Parents spend hours looking for the perfect baby name. The problem is always the same: there are millions of names, but finding the right one is surprisingly difficult...

Memory Leaks: You Freed It. It Didn't Leave

The work finished an hour ago. Nothing is running. And 113 MB just sits there. Restarting fixes it. Which means nothing is fixed. Here is the missing picture, with real numbers from my machine. You cannot free memory. At all. In Java there is no delete and no free. Your code can only do one thing: cut arrows. int[] data = new int[50_000_000]; // ~190 MB, one arrow to it da...

LLM中如果一个问题容易验证 那么AI就容易学会解决！说说这个特性与P与NP问题的关联性

大模型来了，有个说法是如果一个问题容易验证 那么ai就容易学会解决！说说这个特性与p np问题的关联性 这个说法听起来很直观，但其实混淆了"验证的复杂性"和"学习/求解的复杂性"这两件不同的事。我们把它拆开看。 先把"容易验证"在 P/NP 里的精确定位理清 在计算复杂度理论中： NP = 给定候选解（证书），能在多项式时间内验证其正确性的问题 P = 能在多项式时间内直接求解的问题 P ≠ NP ? = 是否所有容易验证的问题，也都容易求解？ 所以"容易验证"在 CS 里的严格含义是：验证者在多项式时间内工作，不是说 AI 训练成本低。 "容易验证 ⇒ AI 容易学会"——部分成立，但有重要的限定 这个直觉在某些场景下确实成立，原因是"验证"提供了稠密的训练信号： ✅ 成立的情形：验证器可作奖励/过滤 ...

Solon Config Vault: ENC() Secrets, @VaultInject, and a Runtime Key — No Jasypt, No Config Server

Every team has that one application.yml with a database password sitting in plain text, committed to a repo that half the company can read. You know it should not be there. But the fix usually means pulling in Jasypt, standing up a config server, or explaining to your ops team why they need to manage another secret store. Solon takes a much smaller route. There's a built-in plugin called solon-se...

Apache Hadoop Installation

This guide is a collection or a summary on how to install and use a footprint of Apache Hadoop. I tried to follow an old version 2.7.1 guide that I created few years ago and adjusted this to use the latest version. Apache Hadoop 3.5.0 is used below; check the Apache releases page before future installations. These instructions target Linux (Ubuntu/Debian) for development or testing. Production cl...

Day 1: Understanding Cloud Computing — Service and Deployment Models Explained with a Biryani Analogy

Yesterday I announced I'm blogging daily on AWS & DevOps. Here's Day 1 — the fundamentals everything else builds on. ## What is Cloud Computing? Instead of setting up and maintaining infrastructure on-premises, you now access computing resources remotely over the internet — this is Cloud Computing. "Cloud" refers to a network that provides resources over the internet, accessible w...

Processes vs Threads: What's the Actual Difference?

In my operating systems course, we spent a good chunk of time on processes and threads. I knew the words before, but I didn't really get the difference until I saw them compared side by side. Here's what I learned. What's a process? A process is basically a program that's running. When you open a web browser, a game, or a text editor, the operating system creates a process for it. Each...

My AI-Attribution Filter Stopped Over-Matching Ordinary Words. It Still Wipes Any Commit That's Legitimately About Claude Code.

This repo has a git hook that generates commit messages with claude -p, then runs the output through a filter that strips anything that looks like AI self-attribution — no "Co-Authored-By: Claude," no "🤖 Generated with Claude Code" footer, nothing that violates the project's no-AI-attribution rule. A few weeks ago I found and fixed a real bug in that filter: it used bare substring matching, so a l...

My MCP Server Fixed a CWD-Relative Path Bug Once. A Second Hardcoded Relative Path Sat Two Functions Below It, Unfixed.

Last week I fixed a bug in this repo's MCP server where .env was being loaded from a bare relative path — ".env" instead of something resolved against the file's own location. The failure mode was that an MCP client launches server.py as a subprocess with just a command and args, no cwd, so wherever the process happens to start determines whether the credentials load at all. I patched load_env() t...

I built CleanSlate, an open-source coding agent for the IDE, CLI, and SDK

CleanSlate is an open-source platform for running coding agents across your local machine and the cloud. Today, it works through an IDE, CLI, and SDK. Agents can understand a codebase, make changes, run commands, browse the web, and verify their work. We are now building longer-running autonomous cloud agents that can continue working without keeping your machine active. CleanSlate supports mul...

Building Fluentic Style: Making CSS Debugging Work Across Next.js Server and Client

This is part of my Building Fluentic Style series, where I’m writing down the design decisions, tradeoffs, and small surprises from building Fluentic Style. It is one thing to make a styling library feel good in a client-side app. It is another thing to make it feel good in Next.js App Router. In a simple SPA-style development setup, most of the styling loop lives in one place: component r...

Architecting Mainline-Friendly Products

Mainline-friendly products are designed so their board support lives in upstream Linux, U-Boot, and standard build systems instead of a vendor fork. The decision is architectural, not aspirational: it is made when you choose the SoC, design the add-on connectors, and write the device tree — not when the product is already shipping. This article gives the strategic case, the product design rules t...
