Knowledge systems
Markdown, search, documents, structured notes, versioning, retrieval, and the problem of keeping information useful after the initial excitement wears off.
- Why Markdown-to-PDF Still Breaks
Markdown-to-PDF is always a chain of parsers and renderers. I compared common engines and built separate fast and fidelity previews to expose their differences.
- I Built Automatic Backlinks Before Testing the Writing
A writing tool extracted entities and contradictions, but months of data-model refinement happened before testing whether it improved a real manuscript.
- Building Durable Memory Around a Stateless Model
A durable memory design stores facts and narrative history outside the model, retrieves them differently, and reviews every proposed update.
- Why Evidence Weight and Agreement Need Separate Scores
A proof of concept that scores support independently from source disagreement, discounts duplicated evidence, and preserves unresolved conflicts.
- I Built a Search Engine by Hand
Building an inverted index, TF-IDF, and cosine ranking exposed two failures: a dense matrix exhausted memory and mismatched IDs ruined precision.
- I Have Four Edit Histories for the Same Photo
Non-destructive photo editors preserve the original but scatter edit history across proprietary catalogs whose long-term readability is not guaranteed.
