Where It All Began: 2019 re:Invent AWS CDK had just gone GA that year with TypeScript and Python support. At re:Invent 2019, I saw AWS present how to contribute to CDK for the first time. There was no AI back then — everything was manual. Clone the entire monorepo, figure out the Lerna project structure, manually build dependent packages, write L2 constructs, write tests, submit a PR. Every step
I started skeptical. A voice AI with cloned voices, real-time, no app install — running on free API tiers? Seemed overly ambitious. But a few hours later, I had a working app. Here's the full breakdown. Clone Talking is a web app for real-time voice conversations with AI persona clones. Open source. Runs on free API tiers.

Most Markdown editors today assume cloud sync, Electron, or heavy installations. I wanted something simpler. I wanted a Markdown editor that: Works fully offline Opens local .md files directly Saves back to the original file Requires no account, no sync, and no network calls Watch the demo video on GitHub: https://github.com/user-attachments/assets/00d80cbc-ca93-4cfd-86d3-5299895d06b7 So I built
Most coding platforms train engineers to solve isolated algorithm problems. But in real engineering, you rarely reverse linked lists. You debug production systems. You trace issues across files. You deal with incomplete logs, unexpected states, and systems you didn’t write. so I built something around that. Recticode is a platform focused on real-world debugging challenges. Instead of algorithm pu
The Challenge: Beyond the "Lift and Shift" Fatigue The real fear isn’t migration itself—it’s operational fragmentation: different tools, different processes, and different failure modes between the data center and the cloud. After deep-diving into the Nutanix ecosystem, I realized that the goal shouldn't be just moving VMs, but achieving operational symmetry. This is where Nutanix Cloud Clusters
TL;DR macsh is a tiny menu-bar app that mounts SFTP, S3-compatible, and FTP/FTPS servers as native macOS volumes. Open them in Finder, drag files in, edit in place. No macFUSE, no kernel extension, no Recovery-mode reboot. Apache-2.0, free. Heads up: macsh is built with Claude Code. I'm the designer, tester, and maintainer; the implementation is AI-written under my direction. Bugs and decisions
Cuando una aplicación necesita leer un archivo, escribir en una conexión TCP o esperar datos de un disco, el kernel de Linux ofrece tradicionalmente dos caminos: bloquear el proceso hasta que la operación termine, o usar interfaces como epoll y Linux AIO para manejar múltiples operaciones concurrentes. Durante casi tres décadas, esas fueron las opciones dominantes. Pero desde la versión 5.1 del ke
When Google announced the Manifest V3 deadline, the developer community had a lot to say — most of it negative. The service worker model was rightly criticized as a regression for ad blockers and complex extensions. I've now migrated 18 extensions from MV2 to MV3, or built them MV3-native from the start. The commonly documented issues (no persistent background pages, limited webRequest) are real.
