June 2019 Summaries

The text discusses the use of Redux Sagas for handling confirmation modals in applications. It explains that copying common patterns like confirmation modal actions can lead to a cluttered store, and introduces a Redux Saga pattern that simplifies this problem. This pattern involves using a ConfirmAction action to show the modal, then waiting for either a cancel or confirmed action from the user before proceeding with the final action. The text also briefly touches on the implementation of ActionModal components and how they can be customized without needing to store UI-specific details in Redux.

At WWDC, Apple announced updates to HTTP Live Streaming (HLS) specification aimed at reducing live video stream latency. HLS is a segmented delivery technology used for live and on-demand streaming across various devices. However, it has been prone to high latency when used for live streaming. To address this issue, Apple introduced a new low-latency mode called ALHLS. This solution involves partial segments, HTTP/2 pushed segments, blocking playlist requests, playlist delta updates, and faster bitrate switching. While the implementation of ALHLS is complex, it addresses longstanding problems with HLS. However, there are challenges in adoption due to mandatory use of HTTP/2, which isn't widely implemented on many CDNs. The community has also been working on a simpler LHLS solution using chunked transfer encoding, but Apple chose not to involve the community in its ALHLS development.

The text discusses the author's experience learning PHP in the early 2000s and how it is still widely used today, ranking as the 7th most popular language on Github. In response to user demand, a new PHP SDK has been developed by Mux, which serves as a lightweight wrapper for their APIs, making it easy to integrate video experiences into PHP applications. The author also mentions that more SDKs will be released in the future and encourages users to suggest languages they would like to see supported.
