Railsconf 2022 CFP: LSP and Solargraph

Title

Autocomplete is for Ruby too!

Abstract

A concise, engaging description for the public program. Limited to 600 characters.

Do you have editor-envy when you witness other programmers using fancy IDE features like go-to-definition or auto-complete? Perhaps you've only witnessed this with other languages - maybe those with static typing - but that's not how it has to be.

Powerful - albeit sometimes obscure - open source tools with all these features are available for Ruby. Come hear more! I'll explain the building blocks of code intellisense features; something called Language Server Protocol; a Ruby language server called Solargraph; the solargraph-rails gem; and how you can get involved to make them even better.

Troubleshooting local instance of kafka

Command line kafka utilities

If your rails server or consumer cannot connect to Kafka locally you can try using the command line utilities included with kafka to diagnose whether your kafka is set up properly:

Create a topic:

⚡  kafka-topics --create --partitions 1 --replication-factor 1 --topic new-test-topic --bootstrap-server 127.0.0.1:9092

Created topic new-test-topic.

## Current ordering problems:

• the most complicated parts of the system are coupled to orders being placed
  • e.g. order -> payment completed -> branch assignment -> driver assignment
  • “everything initiated by an order” is hard to avoid in standard web apps where user input (requests) initiate all activity.
  • This chain is too long, it’s hard to reason about
• ordering features fight for resources
  • restaurant dashboard vs driver assignment vs order list vs driver list
    • all have different purposes with different requirements in terms of:
      • how often they need to be updated
      • what data is queried
