This was a response to a Hacker News comment asking me what I've been up to since 2010. I'm posting it here since HN rejects it with "that comment is too long." I suppose that's fair, since this ended up being something of an autobiography.

I'll preface this with three things. 1. I prefer schemes over Common Lisps, and I prefer Racket of the Schemes. 2. There is more to it than the points I raise here. 3. I assume you have no previous experience with Lisp, and don't have a preference for Schemes over Common Lisp. With all that out of the way... I would say Common Lisp/SBCL. Let me explain
Now as to why Common Lisp over Scheme
Solr needs opinions, because Solr documentation gives you way too many options. It's hard to navigate the best practices for using Solr. Some of my opinions based on dozens of Solr projects :)
Schema files are a good thing. They are declarative, and not letting them change at runtime prevents all kinds of security issues. Further, classic schema / solrconfig support all of Solr's functionality and are well documented with tons of examples online in blog articles and stackoverflow. Using managed schema or the config API takes a lot of experimentation.
Static configurations can also be easily version controlled. As I've learned as a long time Elasticsearch user, this is one of Solr's advantages. Having an API for changing every underlying config option of your index means finding the code that made the change is rather time consuming.
Static configuration is also good separation of concerns. You cleanly separate

This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

Keep it simple, stupid. You ain't gonna need it.
