Weekend Build Log: Stdout Is the Demo, Not a UI

You sit down on Saturday with one goal. You want a tiny status reporter for later. The coding agent already has a full plan. It wants a dashboard, a worker, and Redis. You did not ask for that extra surface. You asked for a green or red result. This log shows the cut you should make. The Saturday scene The repo is a quiet side project. It holds one script and a data folder. You type a loose prompt anyway. "Make a status page I can demo." The agent treats "page" as ...

Introducción a los Data Lakes Parte 3

Hola a todos! Llegamos al final de la serie. En la primera parte vimos qué es un Data Lake y por qué importa. En la segunda parte conocimos los 5 servicios que forman el núcleo: S3, Glue, Athena, Lake Formation y Lambda. Hoy dejamos la teoría de lado. Vamos a construir el Data Lake completo , con todo el código disponible en un repo abierto para que lo despliegues en tu propia cuenta de AWS en minutos. Acá estamos. Manos a la obra. Qué vamos a construir El escenario...

The File Fence Lab

A Friday review often begins with a polite subject line. The patch claims to fix a 504 on /invoice . Then the file list arrives: a new Redis helper, a line in requirements.txt , a port in docker-compose.yml , and a comment that the timeout was “probably a cache miss.” Nobody asked for a cache. The timeout lived in one function. The model widened the job because nothing in the repo told it where the fence was. This lab treats that leak as a teaching object, not a personality debate. AI codi...

AI agent memory vs RAG — what's the difference?

Most teams building on LLMs end up with two patterns in the same codebase: RAG for looking things up in a corpus, and some hand-rolled memory for remembering what the agent has done or what the user has said. The two are often confused, and the confusion costs real engineering time when one is used in place of the other. RAG retrieves content the agent doesn't already know . Memory retrieves context the agent has already participated in . They share a vector store but they answer...

Building a 2D Terrain Editor: Auto-Tiling, Slopes, and Collision

A 2D terrain editor should let creators think in terrain—not in a catalogue of corners, edge tiles, and one-off fixes. When a map is built tile by tile, a small visual change can become a maintenance problem. Paint a new patch of ground and suddenly every transition, slope, collision boundary, and layer relationship needs attention. That friction is exactly what we set out to remove. The terrain problem with tile-by-tile editing Traditional tilemaps are powerful, but they ask ...

A Four-Signal Placement Gate for Local-First Agent Work

A backend engineer boarded a late train with a half-finished agent run still sitting in a terminal. The laptop held repository tokens inside a local vault, and the next tool call needed a long compile that would wake every fan. Cellular data flickered between two bars and airplane mode, so a naive always-remote setup would stall without warning. An always-local setup would cook the chassis and drain the battery before the next station arrived. That commute is the whole placement problem in mi...

Kubernetes Troubleshooting: What to Check Before You Restart a Pod

Production incident. Pod is failing. Alerts are firing. The instinctive response is often: "Restart the pod and see if it comes back." Sometimes that restores service — but it can also destroy useful evidence. Before restarting, check these five things. 1. Describe the pod kubectl describe pod <pod-name> -n <namespace> Look at: Container state Restart count Last termination reason Probe failures Events This often tell...

How Selenium + Chrome Locked Me Out of My Own Windows Account

I ran into one of those "bugs" that initially looks completely unrelated to your code. My Windows account started getting locked randomly. The weird part was that I knew the password was correct. Sometimes I could log in normally, and sometimes Windows would suddenly say that the account was locked. At first I assumed it was some Windows issue. It wasn't. The clue: Event ID 4625 After checking the Windows Security event log, I found a large number of failed logon even...

Thirty-six, six times six. In the numbers there is craft; in the craft there are numbers. Yin and yang temper each other, and the mechanism lies within.

48-Hour Field Notes: The Receipt That Ended Mid-Brace

The worker log ended on a comma. Not a stack trace, not a timeout banner, just a trailing comma and then the same INSERT running again. I was on hour three of a borrowed coding box, watching a webhook worker “fix itself” by doing the side effect twice. The setup was ordinary. A small HTTP handler accepted a delivery, wrote a row, and enqueued a follow-up job. An agent loop was supposed to patch a parser bug. It had a file-write tool, a shell tool, and a test command. The free remote server wa...

A Private Debt Crisis

Private credit’s rise has made leverage feel routine. Higher rates should push private capital back toward durable, unlevered value creation.
