Learning Docker by Building a Container Engine from Scratch

# Learning Docker by Building a Container Engine from Scratch If you've used Docker for any length of time, you've probably internalized the vocabulary. Images. Containers. Dockerfiles. `docker run -d --name my-app nginx`. It works. You ship code. Everyone's happy. But here's a question: what actu…

1-Click GitHub Token Theft via VSCode Bug — Security Alert

Just by clicking a link, it's possible for an attacker to steal a GitHub token that can read **and write** to your repos — including private ones. This isn't a hypothetical vulnerability or a "theoretical risk" scenario. Security researcher [Ammar Askar](https://blog.ammaraskar.com/github-token-ste…
