In the last article, we made a pretty cool little slider (or “carousel” if that’s what you prefer) that rotates in a circular direction. This time we are going to make one that flips through a stack of Polaroid images.
A shell utility like bash provides built-in commands and scripting features to make it easier to solve and automate various tasks. External *nix commands like grep, sed, awk, sort, find, parallel etc can be combined to work with each other. Depending upon your familiarity with those tools, you can either use ruby as a single replacement or complement them for specific use cases.

pitchfork is a preforking HTTP server for Rack applications designed to minimize memory usage by maximizing Copy-on-Write performance.
Like unicorn (of which pitchfork is a derivative), it is designed to only serve fast clients on low-latency, high-bandwidth connections and take advantage of features in Unix/Unix-like kernels. Slow clients should only be served by placing a reverse proxy capable of fully buffering both the request and response in between pitchfork and slow clients.
You’ll now be able to trigger a webhook test payload to a specified destination directly from the CLI. Previously, developers needed to create a dev store and manually click around with an app installed in order to test their app logic. This manual process added significant time and friction to the development loop. With this new feature, it’ll be easy to test your subscriptions for each topic, so you can see what the payload will look like before your app is in production.
