13 ARTICLESShort cases: playout, graphics, and MOS
Four smaller broadcast problems, including the ones that ended in an escalation rather than a fix.
Dante Virtual Soundcard: "No audio data"
DVS subscriptions failed on an edit suite. The cause wasn't Dante at all. Windows had moved the NIC to a Public profile.
A release that failed on a dot
Jarvis v1.0.0 passed 900+ tests, then stopped in its own deployment rehearsal. The cause was a security check applied one place too many.
Every new asset expired on arrival
Nexio ingest started assigning a 1969 kill date to new media. How I narrowed it down and escalated it with clean evidence.
Nexio ICM on Windows 11: "No Communication"
Ping worked, the control port didn't. Three separate fixes were needed to get the ICM client talking to the AMP servers again.
What a console firmware update actually breaks
After a Yamaha QL5 firmware update, OverDrive lost the board and only 3 of 14 Dante sources came back. Getting to air first, then rebuilding.
Why your Dante network works until it doesn't
APIPA, PTP, and what happens when audio leaves the switch. Lessons from remediating a multi-facility Dante plant.
Read-only first: safer PowerShell on production PCs
Audit before you change, keep a recovery archive, check every exit code, and prove the result afterward.
What to send a vendor
The seven things every escalation should include, so the first reply is an answer instead of a question.
How I write SOPs that people actually use
A master template, a lean template, and the sections that make a procedure trustworthy: author checks, validation, and rollback.
A measurement plan for local LLM inference
Separate prompt processing, token generation, memory pressure, and task quality before comparing configurations.
Drawing the boundary between a portfolio and private AI
Why the public website, invited-user chat, and future API have separate access controls and deployment lifecycles.
Troubleshooting across system boundaries
A practical framework for narrowing a fault across clients, networks, applications, and their dependencies.
Room to grow
The notebook will expand through real work across networking, broadcast and media engineering, systems administration, software and automation, AI, and security. New categories appear as useful material is ready.
Case studies come from real broadcast work, written up with employer names, addresses, and case numbers removed. They don’t include private workplace configurations or unmeasured results.
