The Butterfly Effect: How a single bit changed my career
summary
A single missing execute bit on a startup script breaks deployment and mail flow on 150+ appliances offline during Black Friday, forcing SSH or phone-guided console fixes and a week of triage; the product moves from appliance installs to a SaaS build using Subversion, MySQL, SSH and ad hoc scripts, then adoption of CI ideas, partitioning and testing. Outcomes: single missing execute bit, a homemade Jonathan Test 12 steps, and score improvement 2.5 → 9.5 over nine years with a later startup jump from 1 to 9 in 12 months.
