I built K-Humanizer, an open-source Agent Skill for natural Korean writing

Korean text from LLMs is often grammatically correct but still sounds translated. The word order follows English, abstract nouns hide the action, and the tone is often more formal than the situation needs. I kept seeing those patterns while cleaning Korean text data every day for a month, so I turn...

What Do Software Engineers Actually Do? A Career Guide for Students

Picture a software engineer. Go on, picture one. Most people land on the same image: someone alone in a dark room, headphones jammed on, typing nonstop for eight hours, occasionally cursing at a screen full of green text. It's a fun image. It's also mostly wrong. Coding is part of the job. Obvious...

I copied a "minimal" coding agent. Then I read it — and minimal didn't mean what I thought.

A month ago I started building a coding agent from scratch, with one rule: build first, then read. I'd picked pi as my reference precisely because it was described as the smallest serious harness — four packages, four tools, a system prompt under a thousand tokens, and competitive benchmark scores a...

Why Your AI Agent Can't Execute Its Own Plan: Bridging the Gap Between Local LLM Intelligence and Real-World Software Reliability

Originally published on tamiz.pro. You prompt your agent to orchestrate a multi-step workflow. It generates a beautifully reasoned plan. Then it fails on step three. Or eight. Or quietly produces wrong output that no one notices until it's too late. This isn't a prompt engineering problem. It's an...

Actuator Endpoints in Spring Boot: Allowlist, Don't Just Disable the Obvious Ones

A curl to /actuator/env on a Spring Boot backend with default configuration can return environment variables, system properties, and — in some versions and setups — datasource values. No credentials needed. No exploit needed. All it takes is nobody touching Actuator's security config after adding it...

The AI writes the answer

The AI writes the answer. You still have to put it where it belongs. You open a chat, type what you need, and get a well-written paragraph. Then you open a document, paste the paragraph, adjust the formatting, rewrite a sentence that doesn't quite fit, save a version, and close both windows. The AI...

I built a daily JavaScript puzzle game where a wrong answer physically can't ship

[] + {} — do you know what that prints, or do you think you know? That gap is the whole idea behind What's the Output? — a daily Wordle-style game: one JS snippet per day, three tries to type exactly what it prints, hints when you miss, an explanation of the trap when you're done. The rule that sh...

I Built Format-on-Save for Everything That Isn't an Editor

Editors have had format-on-save for years. The rest of the development environment has not. When a generator, shell command or coding agent writes a file, the bytes usually land exactly as produced. The repository may already have Prettier, Ruff or gofmt, but nothing asks it to run. The mistake is...

Your Automation Dies Quietly: A Weekly Revenue Gate That Caught One Line Dropping From 14 Files to 0

A layoff notice doesn't stop the Claude API invoice — that still lands next month, right on schedule.

It's that I built something first that shows me, automaticall...

State-Funded Loneliness

# I Didn’t Plan to Build a 4,000-Page Site

I did not start Huebloom with a plan to build a 4,000-page website. It grew slowly. One collection suggested another. Repeated work led to small tools, and those tools made the next collection possible. The current dataset now contains 4,184 unique page records. I’m not a developer by training. AI...
