Caching POST requests with Varnish

Caching POST requests  When a client (web browser) wants a regular resource (eg a HTML document or an image) from a web server, it will make a GET request to the server. In a default installation, Varnish will cache such requests, and this will lessen the load on the conventional web server. When a user logs in to a site, or provides some unique or private information, this will be done through a POST request. By default, Varnish will not cache POST requests, but pass them directly to the backend server, unmodified. This is typically a good idea, but sometimes it makes sense to also cache POST requests. When two different users use POST towards a web server, we only want them to receive the same reply if they supplied the same request body. The solution is to make the request body a part of the hash, and let the normal caching logic happen. The result is that only clients who supply the same body will receive the the same reply. This tutorial describes the steps needed to cache

Apple updated Ratings and Review Policy

You can ask users to rate and review your app at appropriate times throughout the user experience. Make the request when users are most likely to feel satisfaction with your app, such as when they've completed an action, level, or task. Give users an easy way to provide feedback on the App Store without leaving your app using the SKStoreReviewController API . You can prompt for ratings up to three times in a 365-day period . Apple App Store Ratings and Reviews When you call SKStoreReviewController.requestReview() while your app is still in development mode, a rating/review request view is always displayed so that you can test the user interface and experience. However, this method has no effect when you call it in an app that you distribute using TestFlight . Apple Developer Documentation

Texture: Keeps the most complex iOS user interfaces smooth and responsive.

Texture Texture is an iOS framework built on top of UIKit that keeps even the most complex user interfaces smooth and responsive. It was originally built to make Facebook's Paper possible, and goes hand-in-hand with pop's physics-based animations — but it's just as powerful with UIKit Dynamics and conventional app designs. More recently, it was used to power Pinterest's app rewrite. As the framework has grown, many features have been added that can save developers tons of time by eliminating common boilerplate style structures common in modern iOS apps. If you've ever dealt with cell reuse bugs, tried to performantly preload data for a page or scroll style interface or even just tried to keep your app from dropping too many frames you can benefit from integrating Texture.
