In this tutorial, we are going to try out a Redis client library for PHP. Unlike the Node.js client we used in the previous tutorials, the chosen PHP client library is synchronous and do not require a callback function.
A time series is an ordered sequence of values that are made over a time interval. You can use time series in statistics, communications, and social networks. I this tutorial we are going to create a simple stock time series Node.js library using Redis Strings. This library records events per second, minute, hour, and day.
In this tutorial, we are going to discover a few more data types like Set, Sorted Set, Bitmap, and HyperLogLog.
Redis (REmote DIctionary Server) is an advanced key-value data store. Read and write operations in Redis are very fast because it saves all data in the memory. Redis can also save data on the hard drive. The official Redis documentation can be found at http://redis.io. Redis is an open sources project used by many companies including Instagram and Twitter. In this tutorial, we will install Redis, install Node.js, and try out several data types.
In this tutorial, we are going to focus on the transferring arbitrary data using WebRTC Data Channel Protocol.
In this part we are going to create a client application which connects two users using signalling server we created in the previous part.
WebRTC (Web Real-Time Communication) is your browser built-in technology with the aim to simplify developing applications using audio and video streams. You can easily build your own Skype in the browser using WebRTC. So the simple idea is that you open up a website and connect with another user immediately. WebRTC API includes camera and microphone capture, video and audio encoding and decoding, transportation layers, and session management.
