experimentation sandbox app

Personal tech sandbox and testing site 🕵️‍♀️

Hosted and available at: https://www.serj-tubin.com/

(also at https://2beens.xyz 🤷🏼‍)

Used tech 🛠

• Golang 🦫🩵to make this all happen 👨🏼‍💻
• Dockerfile and docker/ folder contain configs for running the service stack within Docker
  • cd docker && docker-compose up -d to run it all
• Aerospike to store those visitor board messages 💿
  • there are better choices than Aerospike, I know, just wanted to test Aerospike
  • update: I am thinking to replace it for something else
  • update apr 2023: aerospike killed, using postgresql for visitor board messages
• Tried to use Elasticsearch Stack for logging and monitoring on a different server, but it was kinda hungry for memory, and exceeded the needs of this humble project (will try something else lighter)
  • 2023: Honeycomb, Prometheus/Grafana and Sentry are used now
• Used CloudFlare to put everything behind it, but only paid plans allowed passing of real client ip in the proxied requests
• https://freegeoip.app since 2022, https://ipbase.com, dec 22: https://ipinfo.io
  • used for geo IP data
• http://api.openweathermap.org
  • used for weather data
• GitHub Workflow Actions for a part of CI/CD
  • unit testing
  • static code analysis
  • deploy on new release
• PostgreSQL to store blog posts and personal web history (netlog), notes, etc.
• Redis to store session data
• Prometheus is for metrics (then Grafana to visualize them)
• Honeycomb is for distributed tracing
• Sentry for error tracking and alerting
• VueJS (with Vuetify) to make the frontend part (was my first Vue project, so I don't like it that much)
  • source @ https://github.com/2beens/serj-tubin-vue
• ❗️ Disclaimer: some parts of the system are deliberately unoptimized or complicated for testing ☑️ / learning 👨🏼‍🏫 / trial 🛠 purposes
  • Moreover, some parts are quite old now and thus not very go idiomatic

TODO: Observability (done ✅)

• use otel to collect and send metrics and tracing data
  • for metrics use Prometheus
  • for tracing use free Honeycomb plan
