Programming Challenges

• Pick something and implement it
• The topics are open-ended
• Pairing is suggested
• Want to try some new tech, this is a great time
• You may use any tools that you like, including code generators and AI, but make sure you can roughly explain what your code is going at the end
• Towards the end, we'll ask people to show off their work. A demo or quick code walk through. Nothing crazy, just a couple minutes.
• You must decide what you implement. Consider time, what you can deliver, what you can reasonably demo, and wow factor.

Network Cipher Service

Implement a cryptography service.

• The service should network accessible, but no particular protocols are required. Implement a RAW TCP socket, a REST service, gRPC, RSocket, GraphQL, or whatever sounds fun and interesting.

• You must design the API. There are no wrong answers, but consider the following: a value proposition (or a mock one? don't over think this), flexibility, ability to expand the API, ability to scale it, and usability (may depend on your value proposition).

• Implement one cryptographic cipher. Don't worry, it can be simple like a ROT Cipher.

• Other optional tasks:

  • Implement more ciphers, possibly using 3rd party libraries.
  • Implement tests.
  • Create a client library.
  • Create a GUI or CLI (can be auto generated like a Swagger UI)
  • Expose a service/client contract
  • Add authentication/authorization, user access controlls, etc...
  • Compile it to native-image
  • Containerize it

Make an API Mashup

Take some cool APIs, mash them together and do something even cooler.

• This can be anything that consumes one or more APIs,so it could be a server, cli, Android app, etc...

• It should use an API to do something interesting. Not limited to, but here are some example APIs

  • https://api.nasa.gov/index.html
  • https://openweathermap.org/api
  • https://wiki.openstreetmap.org/wiki/API
  • https://www.omdbapi.com/
  • https://api.chucknorris.io/
  • https://dog.ceo/dog-api/
  • https://developer.marvel.com/
  • https://pokeapi.co/
  • https://funtranslations.com/api/
  • and of course any of the AI related APIs floating around

• Optional tasks:

  • Mash together multiple APIs
  • Add tests
  • Create a GUI or CLI
  • Compile it to native-image
  • Containerize it or otherwise package it for distribution

Rube Goldberg Data Processing Pipeline

Love working with data? Take some, make some fun pipelines and show what you can do.

• Find an interesting data source. There are many free on the web.

• Set up your favorite data processing tools

• Start making your pipelines. They don't necessarily need to be practical or optimally efficient, think Rube Goldberg machine, and do something fun & show off what you can do.

• Optional tasks:

  • Pull together multiple data sets
  • Add tests
  • Create a UI
  • Visualize your pipelines
  • Containerize or package for deployment
