Your Data, Your Privacy: Building a Collaborative Allergy Predictor with Federated Learning

We live in an era where our smartphones know more about our health than we do. From heart rate variability to sleep patterns, personal devices are goldmines for predictive health models. However, the "Health Data Paradox" remains: we want smarter AI to predict things like allergy triggers, but we do...

OzBrain's Shared Memory Architecture: How Multi-Agent Teams Avoid Re-Explaining Context Across Sessions

When you run multiple agents across Claude, ChatGPT, and Cursor, each one starts from scratch unless you manually paste context into every session. OzBrain solves this by exposing a shared knowledge substrate that agents read and write through the Model Context Protocol (MCP). The system routes cont...

Architecting a background-service-based sound manager that survives Android's Doze mode

It was the final ten minutes of a high-stakes client presentation. I was mid-sentence, explaining a complex system migration, when my phone erupted with a loud, aggressive ringtone. The room went silent, but my phone did not. I scrambled to silence it, accidentally hitting the volume buttons while f...

Planning Over Execution: Lessons from 157 Agent Runs and the Rise of Orca-Style Agent Fleets

Originally published on tamiz.pro. The field of AI agents has moved rapidly from single-model executors to complex multi-agent orchestration. But after running 157 agent deployments across diverse task domains, one pattern emerged with striking consistency: planning quality predicts success far bet...

Four Alarm Slots, Three Failure Modes: Building a Nightly Drain That Survives Sleep, Races, and Timeouts

Every night my Mac quietly rewrites my long-term memory. Not metaphorically — a shell script drains that day's Claude Code conversation logs into an Obsidian vault, commits them to a private repo, and leaves a briefing on my desktop. It took three real outages to make it reliable. This is the script...

My Caption Width Guard Passed Every Test. It Was Measuring Text the Renderer Never Drew.

Originally published on hexisteme notes. A user complaint sent me into a caption pipeline: "the subtitles cut to two words in places where the sentence doesn't make sense." The fix I shipped for that complaint introduced a second bug, one word narrower and easy to miss, because the code that measur...

99% token accuracy, zero learning. Field notes from fine-tuning vision models with RL.

Over the past year I have been fine-tuning open vision-language models - 9B dense up to a 35B mixture-of-experts - with supervised fine-tuning and GRPO-style reinforcement learning on verifiable rewards. Most of what I learned was not about algorithms. It was about the ways a training run can look h...

Log Level Design and Rotation: Why Apps Use DEBUG/INFO/WARNING/ERROR

Open any application log and you'll see the same kind of message tagged with different labels: DEBUG, INFO, WARNING, ERROR. Why not just write down everything that happens, in one uniform stream? This post looks at what log levels actually do, and at the companion problem every long-running app even...

Same tokens. Different DNA. Why a Texas notebook must not become a parlor.

Most agent "redesigns" are mood boards. Navy glass. A fake dashboard. The dates and proper nouns already in the file never make it onto the page. /reimagine-it is the opposite contract: extract this source's nouns, dates, and colors, then ship a real artifact (webpage, infographic poster, SVG, Thre...
