Ten years keeping enterprise systems alive taught me what most developers never learn: how things fail, what actually costs money, and why reliability isn't optional. Now I build with that hard-won knowledge.
While others deploy to managed platforms and hope for the best, I design for failure, optimize for cost, and test like systems breakβbecause they do. The 3am debugging sessions aren't just war stories; they're why my code works differently.
Grand Rapids, MI Β· IT Professional Β· 10+ Years Experience
After 10+ years in enterprise IT, I've developed non-negotiable principles that shape everything I build:
π Design for Failure β Your code will break. The network will go down. The API will timeout. Build accordingly. Evidence: 694 tests in NeumanOS, 100% coverage in Lazy Golfing.
π° Respect Resource Constraints β Cloud bills compound. Free tiers expire. Optimize early or pay forever. Evidence: thedeadrobot runs at $0/month, NeumanOS uses local storage instead of cloud.
π‘οΈ Trust Nothing You Don't Control β Clouds fail. Vendors disappear. Data breaches happen. Evidence: Local-first architecture, self-hosted infrastructure, privacy-by-design.
π Observability Isn't Optional β You can't fix what you can't see. Monitor everything. Evidence: Grafana, Netdata, Prometheus, UptimeRobot integration across all systems.

Philosophy: Sustainable systems run on free tiers.
Cost Breakdown:
| Service | Free Tier | Usage |
|---|---|---|
| Cloudflare Workers | 100k req/day | ~50/day |
| Cloudflare KV | 100k reads/day | ~20/day |
| OpenRouter (Llama 70B) | Generous | Primary |
| Twitter API v2 | 1,500 posts/mo | ~56/mo |
Content Strategy:
- Schedule: Mon-Fri 2 posts, Sat-Sun 1 post = 14/week

Philosophy: The simplest solution that works. No extra services, no transcoding, just native Plex playlists.
Why not dizqueTV/ErsatzTV/Pseudo Channel?
| Alternative | Problem |
|---|---|
| dizqueTV | IPTV server + transcoding overhead |
| ErsatzTV | Full .NET media overlay, overkill |
| Pseudo Channel | Abandoned, Python 2 era |
Algorithm: Round-robin episodes across your show rotation with single-commercial breaks. No-repeat guarantee via deque ensures variety across consecutive plays. Position tracking persists between sessions. Shows drop from rotation when exhausted.
Commercial Library: Users build their own library organized by decade or category. Built-in yt-dlp integration helps discover and download clips. Batch download scripts can run as Windows Scheduled Tasks on the server.
Philosophy: Build the curriculum you'd want. Then give it away.
