The aim of a development group is to build business value. Building technical leverage is the focus on increasing the business value a development group delivers over time.
Once again we're experimenting with a paper reading group for our engineering team, this time with more success than previously, albeit in an unintended direction.
Can Duruk wrote up some tips from his experience at Digg, and one of them was about pagination. Let's talk about that.
Sometimes working in middle management feels like being trapped purgatory between making policy and making software. Tom DeMarco's Slack paints a much rosier picture.
Digg's fourth version isn't running anymore, but was an interesting system to work on. This article describes the system architecture, as well as the context behind those choices, and will hopefully be an interesting read for those scaling engineering teams and systems.
In this article I'm releasing real-time analytics for this site, as well as analyzing historical data thus far.
If you're doing analytics, reports or dealing with memory constraints in Redis, you're probably dealing with keeping two sorted-sets mutually consistent. This article also takes a look at using multi/exec to keep it fresh.
Last year Digg released a Streaming API which exposes real-time activity on its site. It's available via JSONP, so this tutorial takes a quick look at dynamically populating a Flot.js graph using the API's data.
Designing a system which scales to a high number of requests isn't critical for most applications, but you'll never know that it was important until after the fact, so it's worth putting some thought into ensuring your architecture can grow with your success.
