Performance optimization is hard because it's fundamentally a brute-force task
I’m not talking about skill, knowledge, or convincing a world focused on radical acceleration that optimization is necessary.

Reverse geocoding is hard
My wife and I run OpenBenches - a crowd-sourced database of nearly 40,000 memorial benches. Every bench is geo-tagged with a latitude and longitude. But how do you go from a string of digits to something human readable? How do I turn -33.755780,150.603769 into "42 Wallaby Way, Sydney, Australia"? Luckily, that's a…

Shardines: SQLite3 Database-per-Tenant with ActiveRecord
There is a pattern I am very fond of - “one database per tenant” in web applications with multiple, isolated users. Recently, I needed to fix an application I had for a long time where this database-per-tenant multitenancy utterly broke down, because I was doing connection management wrong. Which begat the question…
