THE HUMAN IN THE LOOP
About this journal
I build systems to understand them — then write down what the diagrams leave out.
I'm Gábor Lepsényi, a technologist and incurable tinkerer based in Budapest. Independent technical writer focused on practical AI, homelab infrastructure, Raspberry Pi, DevOps, and networking.
Why this exists
Most technical writing online is either recycled release notes or ten-minute miracle builds that quietly omit the parts that break. This journal is the opposite: careful experiments, honest constraints, real measurements, and enough context to reproduce the work on your own hardware.
Editorial principles
- Every claim that can be measured is measured, and the method is shown.
- Failures are documented as prominently as successes.
- Sources are cited; affiliate links, if ever added, are disclosed inline.
- Articles are dated and updates are logged transparently.
Expertise boundaries
I write about what I run: local AI inference, Raspberry Pi and small computers, DevOps and reliability, homelab networking, and the games that keep me debugging. Outside those areas I'll say so plainly rather than pretend authority.
On AI-assisted writing
Some drafts here are produced with AI assistance and then fact-checked, measured, edited, and approved by a human before publication. Nothing goes live without that review. The analysis, the lab work, and the final editorial judgement are mine.
Corrections
If something is wrong, I want to fix it. Substantive corrections are logged in each article's update history with a date and a note. Reach out and I'll investigate.
