2015
Building with one other person
2015.084What a codebase looks like when two people build everything -- 350 commits, and a todo list with two items.
Graph queries for a social feed
2015.041Why a graph database was the only sane choice for a social feed where the interesting question isn't what your friends posted, but what your friends' friends are doing this Saturday.
2014
Two-sided graph
2014.319Adding businesses to a social platform built on Neo4j -- and realizing both sides of the marketplace use the same graph patterns.
The middleware chain
2014.232Two people, one Express app, and eight middleware functions between the request and the response.
Node.js on a Raspberry Pi
2014.005Running a custom Node.js blog engine on a Raspberry Pi at home -- from a 45-day wait and a dead board to DuckDNS, ISP port blocking, and the first external request.
2013
Express middleware chains
2013.288Route handlers don't need to be nested callbacks -- Express middleware chains turn them into a flat, readable sequence.
Zero-downtime deploys
2013.196A bash deploy script and a Node.js process monitor -- SSH, pull, touch a file, the cluster reloads. No CI, no dashboard. The terminal.
Sorting by multiple fields
2013.179A composable predicate function for sorting arrays of objects by multiple fields -- with reverse, primers, and short-circuit evaluation.
Running Node.js in production
2013.149Upstart, clustering, zero-downtime deploys, heartbeat monitoring, and an embedded REPL -- what it takes to keep Node.js running in production in 2013.
Node.js style guide
2013.051Our team's Node.js conventions -- error-first callbacks, early returns, callback alignment, and the formatting rules we drilled into every new developer.
Starting over
2013.036Ditching WordPress for a custom Node.js blog engine powered by libgit2 -- git as the content store, markdown as the writing format, npm for everything else.
2012
Running two systems at once
2012.325Replacing an e-commerce frontend without turning off the old one -- carving over layer by layer while the store takes orders.
The dispatch desk
2012.264A basement, a barcode scanner, and the moment the dispatch desk stopped waiting.
A fifty-line rate limiter
2012.249In-memory rate limiting as Express middleware. No Redis, no external service. Fifty lines, one file.
Connection pooling
2012.202The Node.js MySQL driver doesn't pool connections. Under load, you run out. Fifty lines with generic-pool fixes it.
URL mapping in Redis
2012.162Loading every product, category, and brand URL into a Redis hash at startup, and a middleware that rewrites requests before Express sees them.
Rolling your own search
2012.074Building catalog search with flattened MongoDB documents and application-side scoring when the proper tools don't exist yet.
