Why I love ugly, messy interfaces — and you probably do too Not all products benefit from ultra-minimalistic UIs:

Products that solve big, hairy problems are life savers. I love using these products because they work so damn well. Sure they’re kind of a sprawling mess. That’s exactly why they work!

The simplest way to achieve simplicity is through thoughtful reduction One way to arrive at products that are as complex as they need to be, is through thoughtful reduction:

The process of reaching an ideal state of simplicity can be truly complex, so allow me to simplify it for you. The simplest way to achieve simplicity is through thoughtful reduction. When in doubt, just remove. But be careful of what you remove.

Stranger Danger: Addressing the Security Risk in NPM Dependencies A presentation from the O'Reilly Fluent Conference by Snyk co-founders. I linked to the buffer exploit blog post last week, this talk covers the exploit, and shows you how to use Snyk in your development workflow.

JQL - Mixpanel MixPanel using V8 to run your map/reduce/group analytic queries.

This is the age of server-less architecture, we’re going to see a lot more services offering hosted queries.
