I built Memory Bank for my home infrastructure repo. Three months later, I finally applied it to the system that actually makes money. Then during a real project, the whole data architecture changed.
When ‘systemctl status’ says everything is fine but your network is down, you learn that hard NFS mounts and critical services don’t mix.
A 404MB log file growing at 160MB/day. 87% of it was mDNS traffic. One thermostat was sending 66,000 queries with zero responses. The fix wasn’t log rotation - it was understanding why.
Three root causes, 10+ debugging iterations, and 2792 permission errors: How platform-specific build artifacts turned my seamless dev workflow into a troubleshooting marathon.
How an AI assistant saturated SSH connections, crashed a Pi, triggered rate limiting, and why that incident led to mandatory safety rules for AI-assisted infrastructure management.
Running CrowdSec felt safe until a routine audit revealed SSH brute force attacks going completely undetected - because the security tool was watching the wrong log source.
2025-10-24 - Discovering Mistral 7B on Mac Mini M4 with Apple Silicon Monitoring 🎯 Key Insights Undocumented Infrastructure: Ollama + Mistral 7B installed 4 days prior but completely missing from Memory Bank documentation Apple Silicon Monitoring Gap: btop GPU monitoring is Linux-only; asitop is the correct tool for M4 GPU/Neural Engine observation M4 Efficiency Characteristics: Inference so fast (40-80 tokens/sec) that GPU activity appears as brief power blips rather than sustained load 📝 What Happened Session started with a simple question: “Did we install Mistral on here?” Memory Bank had no record of it, but systematic search revealed Ollama v0.12.6 with Mistral 7B fully operational, installed approximately October 20th. ...
Phase 6 Testing Complete - Production Blog System Validated Date: 2025-09-21 Project: chungus-net Session Type: Testing & Validation Duration: ~2 hours Completion: 47/67 tasks (70%) 🎯 Key Insights The comprehensive Phase 6 testing validated our production-ready global blog system with 100% success across all 8 testing scenarios.

Task 5.6 Implementation - Session 1 🎯 Key Insights Multiple sessions per day workflow already implemented via Task 4.6 /stop command integration provides optimal timing for blog creation Session numbering and conflict resolution working correctly 📝 What Happened Started implementation of Task 5.6 to handle workflow for multiple development sessions in single day. Analyzed existing integration between /stop command and blog creation system. Found that Task 4.6 already provides the core multiple sessions handling. ...
Task 5.6 Implementation - Session 2 🎯 Key Insights Session numbering system working correctly with suffix pattern Blog index maintains chronological order within same-day entries Context preservation between sessions operates as expected 📝 What Happened Second session of Task 5.6 implementation. Tested multiple session handling by creating test entries and verifying the conflict resolution system works correctly. Confirmed that the suffix pattern (session-2) is applied automatically. 🔧 Technical Details File: task-5-6-session-2.md Date: 2025-09-21 Session: #2 (second session of day) Focus: Testing session numbering and conflict resolution 💭 Reflections The multiple sessions workflow is robust and handles same-day sessions elegantly. The index ordering logic maintains chronological order within date groups as expected. ...
