💾 52-Year-Old Tape May Reveal Lost Chapter of Unix History
The discovery underscores the fragility of digital history and the value of preservation efforts. If successfully recovered, this version of Unix could provide invaluable insight into the foundations of modern operating systems.
Researchers at the University of Utah have unearthed a 52-year-old tape labeled ‘UNIX Original From Bell Labs V4’, likely containing the fourth edition of Unix from 1973. The artifact, connected to pioneers such as Jay Lepreau and Martin Newell, could represent a unique surviving copy of the first Unix version partially written in C. It’s now being carefully restored at the Computer History Museum under Al Kossow’s supervision, potentially filling a key historical gap in computing evolution.

⚙️ Building a CI/CD Pipeline Runner from Scratch in Python
A deep technical exploration revealing how CI/CD engines actually function. Perfect for developers and DevOps engineers eager to grasp the mechanics of orchestration, concurrency, and dependency management beyond pre-built tools.
This article walks readers through the creation of a custom CI/CD runner in Python—akin to GitLab Runner or GitHub Actions. It incrementally develops the system from a single-job executor to a full-featured orchestrator supporting stages, parallel jobs, artifact handling, and dependency resolution. The author also covers key orchestration algorithms like topological sorting and dependency graphs, finishing with practical performance insights and extensibility ideas.
