Why Fixed-Window Rate Limiters Fail (And How to Fix Them with Math)

If you’ve ever built an Express API, you’ve probably reached for standard rate-limiting middleware to protect your login or payment endpoints from DDoS and brute-force attacks. Under the hood, most simple limiters use a Fixed-Window Counter. It’s easy to write: count incoming requests, and once th...

I Got 28 TPS Out of Free Kaggle GPUs. Here's What It Took.

I want to be upfront about something: this whole project runs on free Kaggle T4 notebooks, an AWS EC2 t3.micro relay that costs almost nothing, and public internet. No A100s. No private datacenter network. No budget. And yet, ShardFlow v2.1 hits 28.10 TPS peak on Qwen2.5-7B across two separate clou...

Generate endless Roblox quests with AI (and cache them so it's cheap)

Hand-written quests run out. Players finish your content faster than you can write it, and the tenth "collect 10 wolf pelts" quest feels like filler. You can generate quests on the fly instead — tuned to the player and the place. One request local Cortex = require(game.ServerStorage.C...

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.

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.

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.
