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
If you don't care about the explanation, scroll down to find the code, it's 50 some odd lines and written by someone who doesn't know any better. You have been warned.
This is a very simple proof of concept jitting RPN calculator implemented in python. Basically, it takes the source code, tokenizes it via whitespace, and asks itself one simple question: am I looking at a number or not?
First, let's talk about the underlying program flow. Pretend that you are a shoe connoisseur with a tiny desk. You may only have two individual shoes on that desk at any one time, but should you ever purchase a new one or get harassed by an unruly shoe salesman without realizing that you have the power to say no (or even maybe?), you can always sweep aside one of the two shoes on the desk (the one on the right, because you're a lefty and you feel that the left side is always superior) onto the messy floor, put the other shoe on the right hand side, and then place your newly acquired shoe in

Solution: Ubuntu distros lower than 18.10 will not work in this laptop, as minimum kernal version required is 4.18.
So install ubuntu 18.10 / xubuntu 18.10 / lubuntu 18.10 / kubuntu 18.10 in UEFI mode
