Introduction to Locality-Sensitive Hashing

These techniques can be used, for example, to filter out duplicates of scraped web pages at an impressive speed, or to perform near-constant-time lookups of nearby points from…

Build versus Buy
A few years ago I was working on a contract negotiation with Splunk, and we kept running into what felt like a pretty unreasonable pricing structure. They wanted some number of millions of dollars for a three year license, which felt like a high price to pay for roughly thirty-two ascii characters in a particular…

The Container Throttling Problem
This is an excerpt from an internal document David Mackey and I co-authored in April 2019. The document is excerpted since much of the original doc was about comparing possible approaches to increasing efficency at Twitter, which is mostly information that's meaningless outside of Twitter without a large amount of…

AWS IAM Roles, a tale of unnecessary complexity
This is going to be a highly opinionated blog post. I think AWS is great and use it daily, but their implementation of IAM is unnecessarily complicated.

How to handle 1000s of concurrent users on a 360MB VPS
There has been some recent confusion about how much memory you need in a web server to handle a huge number of concurrent requests. I also made a performance claim on the STS list that got me an unusual number of private emails.

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.

Yes, I know, it’s a long text, and it was my conscious decision to write it in this way. But fear not! Imagine that you read a book, take a look at the introduction and first few interesting sections, think about it and then find time to read further.

Writing is one of the most powerful forms of communication, and it’s useful in a multitude of roles and contexts. As a blog-writing , documentation-authoring , twitter-shitposting DevEx engineer I spend a lot of my time writing.
