About This Atlas
Who maintains Software Development Atlas, why it exists, and how its freshness signals should be interpreted.
Personal learning atlas by Tran Trong Thuc · About this Atlas · Atlas last updated Sep 9, 2026
Software Development Atlas is the personal learning and reference system of Tran Trong Thuc (@thucne).
I use the Atlas to turn software-engineering topics I study into material that is easier to revisit, verify, connect, and reason from later. It is intentionally more than a notebook: important topics can include source-backed explanations, diagrams, decision guides, architecture walkthroughs, and interactive teaching tools when those improve understanding.
What the freshness signals mean
Every normal Atlas page carries a freshness classification, a lastVerified date, and a review target. The page header turns those fields into a visible freshness indicator.
A page that is current is still inside its review window. A page that is due soon is approaching the end of that window. A page marked verification overdue has passed its review target and should be re-checked before relying on details that may have changed.
An overdue review does not automatically mean the lesson is wrong. It means the Atlas no longer has recent verification evidence for that page.
The separate Atlas last updated date is a site-level maintenance marker. It is not a substitute for each lesson's own verification date.
Corrections and improvements
The Atlas is Git-backed. Each lesson exposes an Edit on GitHub action so corrections, clearer explanations, source updates, and maintenance work can start from the canonical MDX file.
