How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

Array intersect

Fastest function to intersect a large number of big arrays in javascript, without dependencies

• The compressed version is only 345 caracters long.
• Faster than common libraries, even a large number of arrays, or on very big arrays. (See benchmarks)

A temporal database system on PostgreSQL using table inheritance and the rule system.

This is a data structure for a Slowly-Changing Dimension Type 2 temporal database, implemented using only PostgreSQL >= 9.0 features.

Any application code is completely unaware of the temporal features: queries are done against a view that behaves exactly like a plain table (it can be SELECTed, UPDATEd, INSERTed INTO and DELETEd FROM), but behind the scenes the database redirects the queries to backend tables holding actual data, using the PostgreSQL rule system.
