One of my favorite technology trends of the past few years has been the emergence of engineering blogs. They are, mostly, a recruiting tool, but that doesn’t mean that you can’t learn a lot about how companies operating at varying levels of maturity and scale go about their business. Here are the engineering blogs I’m following right now: * Airbnb Nerd Blog * Backing & Hacking (Kickstarter) * Bitly Engineering Blog * CloudFlare * Code as Craft (Etsy) * code.flickr - One of the original engineering blogs. * The Corner (Square) * Coursera Technology * DocuSign Dev Blog * Dropbox Tech Blog * Facebook Engineering Blog (older stuff) * Foursquare Engineering * Google Engineering Tools * IMVU Engineering Blog - One of earliest companies to publicize its continuous deployment process. * Instagram Engineering * Last.HQ (Last.fm) * LinkedIn Engineering * Lyft * Making Pinterest * Medium * The Netflix Tech Blog * NPR News Apps Blog * Paperless Post Dev Blog * Pinterest * Several People Are Coding (Slack Engineering) * SlideShare Engineering Blog * SoundCloud Backstage * Spotify Labs * Tumblr Engineering * Twitter Engineering * Uber Engineering Blog * Viget Extend * Vine * Wayfair Engineering * Wealthfront Engineering * Yahoo * Yammer Engineering * Yelp Product & Engineering Blog * Zenefits What sorts of things are companies publishing on engineering blogs? Here are a few examples of particularly good engineering blog posts I’ve read over the years: * Lessons Netflix Learned from the AWS Outage is a great post-mortem on how Netflix dealt with a major outage that affected them in surprising ways. * Building a recommendation engine, foursquare style explains the computational shortcuts you can take when you’re dealing with a lot of data. * The Etsy Way rounds up a number of posts that explain how Etsy created its engineering culture. * Creating an interface for geofences is a look at how Flickr built an interesting feature. * Twitter explained how they moved to a new datacenter. * LinkedIn’s three part series on building their iPad app was epic. This is just a small sample of the great stuff that companies are posting to their engineering blogs these days.
