Everyone that already uses RxJS knows that the added value of RxJS mostly comes from the provided operators. These operators enable us to develop complex scenarios in a fairly comprehensible manner.  Right now RxJS already provides over 100 different operators and it is also possible to extend this huge list by developing custom operators.  But wait, do you actually know how operators are internally structured? How is this magic piece of code developed that brings so much power? Everyone uses RxJS operators on a daily bases, but no one really knows about the internals of it! Within this talk, we will take a deep dive into the internals of RxJS to understand how operators are developed. This will first make us understand how these operators work and second enables us to write our own operators to fully embrace the power of RxJS.

We ultimately will swap out the OAuth token generation for the OAuths that are supplied per client application on The Monitaur.com's webapp. The Montiaur application is made to monitor any server-side applications / instances of service layers and aimed to support NTier architecture. The application is an Asp.NET Core 3.1 WebAPI project with SignalR as one of the data-transfer layers. The front-end of the application is an Angular CLI Web Application. To submit alerts from your apps, first create a project on TheMonitaur.com and add as many client applications as you wish. Each client application will include an OAuth token you can submit either as a WebAPI Authorization Header, querystring for websocket, or as a first transmission for Tcp. We are also using AG Grid for our message received grid. Alerts from your different app layers can be submit to The Monitaur servers through Tcp, Websocket, or WebAPI. Additionally, client nuget packages are available at https://www.github.com/liveordevtrying/TheMonitaur for .NET applications that include a wrapped Tcp client, Websocket client, or WebAPI client. We are also using an IdentityServer4 for the Authorization server, SQL server for the database layer, and Dapper instead of Entity Framework for our object relational model (ORM). The completed project is available at: https://www.themonitaur.com. This project is created and maintained by LiveOrDevTrying with Pixel Horror Studios.للاستفسار : فيس بوك : https://www.facebook.com/eslam.khder.98 لينكد ان : https://www.linkedin.cn/in/eslam-khder-4145351b0 ============================================================ WebSocket From Wikipedia, the free encyclopedia Jump to navigationJump to search WebSocket Websocket connection.png A diagram describing a connection using WebSocket International standard RFC 6455 Developed by IETF Industry Computer science Connector type TCP Website Official website WebSocket is a computer communications protocol, providing full-duplex communication channels over a single TCP connection. The WebSocket protocol was standardized by the IETF as RFC 6455 in 2011, and the WebSocket API in Web IDL is being standardized by the W3C. WebSocket is distinct from HTTP. Both protocols are located at layer 7 in the OSI model and depend on TCP at layer 4. Although they are different, RFC 6455 states that WebSocket "is designed to work over HTTP ports 443 and 80 as well as to support HTTP proxies and intermediaries", thus making it compatible with HTTP. To achieve compatibility, the WebSocket handshake uses the HTTP Upgrade header[1] to change from the HTTP protocol to the WebSocket protocol. The WebSocket protocol enables interaction between a web browser (or other client application) and a web server with lower overhead than half-duplex alternatives such as HTTP polling, facilitating real-time data transfer from and to the server. This is made possible by providing a standardized way for the server to send content to the client without being first requested by the client, and allowing messages to be passed back and forth while keeping the connection open. In this way, a two-way ongoing conversation can take place between the client and the server. The communications are usually done over TCP port number 443 (or 80 in the case of unsecured connections), which is beneficial for environments that block non-web Internet connections using a firewall. Similar two-way browser–server communications have been achieved in non-standardized ways using stopgap technologies such as Comet or Adobe Flash Player.[2] Most browsers support the protocol, including Google Chrome, Firefox, Microsoft Edge, Internet Explorer, Safari and Opera.[3] Unlike HTTP, WebSocket provides full-duplex communication.[4][5] Additionally, WebSocket enables streams of messages on top of TCP. TCP alone deals with streams of bytes with no inherent concept of a message. Before WebSocket, port 80 full-duplex communication was attainable using Comet channels; however, Comet implementation is nontrivial, and due to the TCP handshake and HTTP header overhead, it is inefficient for small messages. The WebSocket protocol aims to solve these problems without compromising the security assumptions of the web. The WebSocket protocol specification defines ws (WebSocket) and wss (WebSocket Secure) as two new uniform resource identifier (URI) schemes[6] that are used for unencrypted and encrypted connections respectively. Apart from the scheme name and fragment (i.e. # is not supported), the rest of the URI components are defined to use URI generic syntax.[7] Using browser developer tools, developers can inspect the WebSocket handshake as well as the WebSocket frames.[8] Contents 1 History 2 Browser implementation 3 JavaScript client example 4 Web server implementation 5 Protocol handshake 6 Security considerations 7 Proxy traversal 8 See also 9 Notes 10 References 11 External links History WebSocket was first referenced as TCPConnection in the HTML5 specification, as a placeholder for a TCP-based socket API.[9] In June 2008, a series of discussions were led by Michael Carter that resulted in the first version of the protocol known as WebSocket.[10] The name "WebSocket" was coined by Ian Hickson and Michael Carter shortly thereafter through collaboration on the #whatwg IRC chat room,[11] and subsequently authored for inclusion in the HTML5 specification by Ian Hickson. In December 2009, Google Chrome 4 was the first browser to ship full support for the standard, with WebSocket enabled by default.[12] Development of the WebSocket protocol was subsequently moved from the W3C and WHATWG group to the IETF in February 2010, and authored for two revisions under Ian Hickson.[13] After the protocol was shipped and enabled by default in multiple browsers, the RFC 6455 was finalized under Ian Fette in December 2011. RFC 7692 introduced compression extension to WebSocket using the DEFLATE algorithm on a per-message basis.Learn more about Substrate: https://parity.io/substrate Pierre Krieger, Parity Technologies, presents a deep dive on libp2p at Sub0, the first Substrate developer conference.

Getting started with serverless can be a bit daunting at times with creating the functions, configuring them, configuring api gateways and what not. In this talk you will learn about the magic of rapid serverless api development using AWS Chalice. One of the best part of serverless is that you dont need to think much about the provisioning and deployment of your service once you are ready to deploy, and Chalice framework makes that a reality when working with Python. With its super simple CLI which scaffolds and deploys on AWS Lambda within minutes, and its helpful utility libraries you can create fast, scalable services in Python in no time. We will demonstrate on how to get started using this simple framework, and what are some of the challenges to consider when working with serverless on AWS Lambda. How does local development work and what are some of the things to look out for when building using Chalice.One of our engineers hooked a new test script called "blinkenlights" to stress test that we can receive all the notify packets from the Kazoo. This also shows off the new Operator Console UI, which relies on Websockets. Test Setup A calls B, B answers, B parks A, waits 5 sec then picks up call from parking slot, then waits for 5 sec and hangs this is to test that we get all the notify packets. The load test is variable, but this current setup is running 10 calls at the same time. Blinkelights receives them and makes assertions about the sequence and content. It also measures up delay between the action and the arrival of notify (BLF) so that if there’s a deviation it can perform corrective actions.iOS : Getting PCM data of HLS from AVPlayer [ Gift : Animated Search Engine : https://bit.ly/AnimSearch ] iOS : Getting PCM data of HLS from AVPlayer Note: The information provided in this video is as it is with no modifications.
