Azure Websites provide a mechanism to store our secret keys in Azure and Azure will take care of inserting them into the running application.

Responding to user input is arguably the core of what we do as interface developers. In order to build responsive web products, understanding how touch, mouse, pointer and keyboard actions and the browser work together is key.

We present jump consistent hash, a fast, minimal memory, consistent hash algorithm that can be expressed in about 5 lines of code. In comparison to the algorithm of Karger et al., jump consistent hash requires no storage, is faster, and does a better job of evenly dividing the key space among the buckets and of evenly dividing the workload when the number of buckets changes. Its main limitation is that the buckets must be numbered sequentially, which makes it more suitable for data storage applications than for distributed web caching.

When engineering management is done right, you're focusing on three big things. You're directly supporting the people on your team; you're managing execution and coordination across teams; and you're stepping back to observe and evolve the broader organization and its processes as it grows.

Design for accessibility, like you should, and give IE8 users the most basic experience. You’ll be fine, and the Web can move forward.

There’s a meme, originating from certain corners of the Functional side of programming, that “patterns are a language smell”. The implication being that “good” languages either already encode the patterns as language features, or they provide the tools to extend the language such that modeling the pattern explicitly isn't needed. This misses the point on rather a lot of levels.

Have you wasted a few hours debugging some condition only to find a query or function something was returning nil? Spent time optimizing queries only to forget to do eager loading? Scrolled through your development log past 100s of lines for requests for images, css and javascript that you don’t really need to refer? We have all been there and these 7 gems solve exactly these problems.

In order to more realistically simulate the behavior of solid objects, we have to check if they collide with each other every time they move, and if they do, we have to do something about it, such as applying forces that change their velocities, so that they will move in the opposite direction.
