Referee Lights in Go on AWS: simple, light, reliable and fast

ZeroW and Australian Powerlifting League (APL) host powerlifting meets most weekends.

Developing and deploying a simple, reliable tool for:

• refereeing meets reliably in real time

• integration with meet management software

• integration with web streaming

was a high priority. I had been experimenting with different languages and decided to take Go for a ride. This was the outcome. Hosted on AWS ECS Fargate

• Load the lights page on the main computer.

• Center referee calls “platform ready” and clicks the corresponding button

• Timer starts; lifter executes lift

• referees make their decision: good lift or no lift. Once all 3 referees have submitted a decision the collective result is shown

• a green dot below each light indicates which referee has submitted a decision

• Once the collective decision is displayed, the second timer starts for the lifter to submit next attempt
