5 Tips for Thinking in Clojure

Sent by the Pragmatic Programmers, LLC. • 9650 Strickland Rd Ste 103-255• Raleigh NC 27615 - Feb. 21st, 2018

1. Rely on your REPL. Clojure (like other LISP languages) intends to provide a "live" development experience where you are actively manipulating and testing the program while you develop the code. To take full advantage of Clojure, it's essential to work in a development environment that allows you to interactively evaluate parts of your code while you develop. We are fortunate to have a variety of tool choices in Clojure that can satisfy those demands.
2. Maps, not Objects. Developers coming from object-oriented languages are likely to look for the ability to create classes or objects to hold their data. Clojure takes a more direct and flexible approach to data, primarily storing information attributes in heterogenous maps. Rather than providing class-specific interfaces, Clojure provides a single generic data interface for creating, accessing, and transforming att

Hobby Projects

This serves as a repository of ideas that have popped into my head. As I have time, I play around with one.

1. Mute Button - Automatically mute television commercials using machine learning and Spark
2. NYC Taxi - A cabbie once told me that the length of each trip he takes is much longer than it was before. Use math to prove/disprove it. This data needs a lot of cleanup and profiling before it can be properly analyzed. NYC Taxi Data Cleanup Project
3. Heart Rate Anomaly Detector - Automatically detect afib in the fitbit HR
4. Picam Fun - Detect movements and objects from images work started here
5. Listicle - Organize online articles for reading frontend [backend](https://github.com/brycemcd/email-l
