Case-first
Each note uses a real case structure, not a generic summary.
- Symptom (what failed)
- Constraint (why it happened)
- Change (what was done)
- Check (how correctness stayed stable)
Short notes on large-scale data mining under real limits: checks, pipeline patterns, automation, LLM systems, and twin builds when they affect results.
Short notes that help on the next run
Large data work fails in boring ways: type drift, memory growth, bad partitions, slow writes. This newsletter is built around fixes, checks, and decisions that can be reused.
What to expect
- One short note at a time
- Clear checks and a next step
- No spam and easy unsubscribe
Guides that end in a choice
Notes link back to guides with trade-offs and a clear next step.
- CSV vs Parquet
- Sampling without bias
- Chunk sizing decisions
- Validation habits
Templates that save time
Each note includes a small reusable block: checklist, plan, or run notes format.
- Pipeline review checklist
- Sampling validation checklist
- Conversion plan
- Run notes format

Is it marketing?
No. Notes focus on repeatable work: constraints, changes, and checks.
Will it stay low frequency?
Yes. The site is built for depth, not volume.
Can it be used across domains?
Yes. The content focuses on pipeline behaviour, not domain terms.
When will real subscription be added?
After deployment. The page is structured so a provider embed can replace the placeholder form.
