<jack> - Solving a Math Puzzle with Ruby

https://www.jackchristensen.com/2009/08/08/solving-a-math-puzzle-with-ruby.html

Solving a Math Puzzle with Ruby. On page 212 of the excellent book The Art of Game Design by Jesse Schell. The author presents the following puzzle as a negative example of the puzzle principle of “make it easy to get started”. The problem is to find the value of all the letters. Some initial examination of the equation yields a few clues. To start with, a zero would not typically be written on the leftmost digit of a multiplier. So C. Cannot be zero. Furthermore, D C=D. This means that either C. I would...

Hashes can be serialized to an hstore column. hstore is a PostgreSQL key/value type that can be indexed for fast searching.

React2FS - React to File System Changes. React2FS is a standalone, cross-platform, file system watcher written in Go. React2FS’s primary use is as development tool to automatically run tests or rebuild a package when a source file changes. For example, from a Go package directory simply run.

Custom Aggregates in PostgreSQL. Given a bank account of debit and credit transactions, what is the greatest balance the account ever had? Given a hotel with arrivals and departures, what is the greatest number of guests the hotel ever had? Both of these are examples of finding the greatest running total. Finding the greatest running total is a great exercise with which to explore some of the lesser known features of PostgreSQL such as window functions, custom aggregates, and C functions.
