Some Reasons to Measure
A question I get asked with some frequency is: why bother measuring X, why not build something instead?

SQL vs. NoSQL Is the Wrong Distinction
A misconception that I held for a really long time was that systems that use SQL (Structured Query Language) are by definition relational databases, and systems that don’t (e.g., MongoDB, Cassandra) are non-relational.

Life Before Unicode
Unicode definitely added a lot of complexity to string handling, and people who use languages with ASCII alphabets exclusively may think it's unjustified. However, I'm a non-ASCII language speaker who's old enough to remember the alternatives, and the alternatives are far worse than the complexity of Unicode.

Strict Tables – Column type constraints in SQLite - Draft
SQLite strives to be flexible regarding the datatype of the content that it stores. For example, if a table column has a type of "INTEGER", then SQLite tries to convert anything inserted into that column into an integer. So an attempt to insert the string '123' results in an integer 123 being inserted. But if the…
