Cadmium: A pure Crystal NLP library

I've been working on a library to provide useful NLP (natural language processing) functionality in Crystal. The library is called Cadmium and is still in alpha with new features being added daily. Currently it provides functions such as tokenization, string distance, stemming, inflecting, n-grams, tf-idf (term frequency-inverse document frequency), and transliteration; with many more features coming in the near future.

Ngrok wrapper for Crystal

Ngrok is a well known http tunneling software for sharing local projects with the outside world. It can be an indispensable resource when developing websites, bots, etc.

I created to make connecting ngrok to your Crystal projects just a little bit easier. It currently has examples using Kemal and Tourmaline, but it's fully possible to use it with Amber, Lucky Framework, or any other web-based framework.
