A collection of patterns & modules for responsive emails
One image for all screen resolutions and different devices is not enough. An image per pixel is too much - so how can someone automatically choose the optimal responsive image sizes?
Responsive websites, even the most modern ones, often struggle with selecting image resolutions that best match the various user devices. They compromise on either the image dimensions or the number of images. It's time to solve these issues and start calculating image breakpoints more mathematically, rather than haphazardly.
Today we want to show you how to create a responsive image gallery with a thumbnail carousel using Elastislide. Inspired by Twitter’s “user gallery” and upon a request to show an integration of Elastislide, we want to implement a responsive gallery that adapts to the view-port width. The gallery will have a view switch that allows to view it with the thumbnail carousel or without. We’ll also add the possibility to navigate with the keyboard.

REST is an acronym for REpresentational State Transfer and an architectural style for distributed hypermedia systems. Roy Fielding first presented it in 2000 in his famous dissertation.
Like other architectural styles, REST has its guiding principles and constraints. These principles must be satisfied if a service interface needs to be referred to as RESTful.

Or, if something else already restored a copy for you, it can just connect and run the same checks against that instead.

ReSwift is a Redux-like implementation of the unidirectional data flow architecture in Swift. ReSwift helps you to separate three important concerns of your app's components:
State: in a ReSwift app the entire app state is explicitly stored in a data structure. This helps avoid complicated state management code, enables better debugging and has many, many more benefits...
Views: in a ReSwift app your views update when your state changes. Your views become simple visualizations of the current app state.
State Changes: in a ReSwift app you can only perform state changes through actions. Actions are small pieces of data that describe a state change. By drastically limiting the way state can be mutated, your app becomes easier to understand and it gets easier to work with many collaborators.

Each time the command line "retronas" tool is run, the core project is updated to its latest stable release. Third party tools that RetroNAS installs are done so via a mix of Debian APT repositories (which can be managed via standard package manager and system update tools), and for specialised tools via upstream project pages (these can be updated by re-running the tool installer).
