Are you a business owner looking for PHP web development services or ASP.Net development services, but unable to decide the right technology for your project? Are you looking for the pros and cons of ASP.Net and PHP to take an effective decision?  I have tried to make this task easy for you by comparing ASP.Net and PHP in a very simple way.

There are a number of articles and blogs available over the Internet with a large amount of information about PHP Vs ASP.NET. Unfortunately, most of these blog posts are biased and typically based on promoting one over the other.  

In this blog post, I have done an unbiased comparison between the two most popular technologies i.e. PHP and ASP.NET in today’s world. 

On one side, we have PHP, the world’s most used and popular technology on the internet with billions of dedicated PHP developers across the world. On the other side, we have ASP.NET, a Microsoft platform. Sometimes, it becomes quite difficult to have a clear decision about which technology (Php or Asp.net) should we prefer for our application or website development project? 

Here is an elaborative comparison guide that helps you figure out the best technology for your next web app development project. I can assure you that after reading this article, you’ll have a clear idea about which technology suits you better. Moreover, you can share your thoughts and feedback in our comment box. We welcome your positive feedback for appreciating our work. Also, I will be happy to hear from you if you want us to do some improvements to my article.

The first viewer issue, or the difficulties of converting WebRTC video streams to HLS

Reading time7 min

George shut his laptop and rubbed his sleep-deprived red eyes. "Customers continue to complain about stream freezing; the new fix package did not help at all! What do I do with this (censored) HLS?" he said.


The browser is not only hypertext, but also a streamer


Browsers have had players for a long time, but the story is different with the video encoder and streaming. Now, in almost any browser of the latest version, we can find modules for encoding, streaming, decoding, and playback. These functions are available through the JavaScript API, and the implementation is called Web Real Time Communications or WebRTC. This library built into browsers can do quite a lot: capture video from a built-in, virtual or USB camera, compress it with H.264, VP8, and VP9 codecs, and send it to the network via SRTP protocol; i.e., it functions as a software streamer video encoder. As a result, we see a browser that has something similar to ffmpeg or gstreamer, compresses video well, streams on RTP, and plays video streams.

In JavaScript, state management is a hot of discussion these days. When it comes to implementing state management, developers often find it challenging dealing with boilerplate code in Redux. Hence, MobX has proved to be a good alternative to Redux which gives the same functionality with less code to write. However, both state management tools work well with React.

Let's first have a look at the common things between the two:

1) Both support time-travel debugging
2) Both contain open-source libraries
3) Both provide a client-side state management
4) Both provide huge support for React native frameworks

In this blog, we have listed all the pros and cons of both state management solutions. It will help web developers to choose the best one for their next project. Before discussing this, we have compared both Redux and Mobx based on some parameters as given below:

Publish and Play


There exist two main functions of WebRTC operation on the server side in the field of streaming video: publishing and playing. In the case of publishing, the video stream is captured from the web camera and moves from the browser to the server. In the case of playing, the stream moves in the opposite direction, from the server to the browser, is decoded and played in the browser’s HTML5 <video> element on the device’s screen.

RTSP is a simple signaling protocol which they cannot replace with anything for many years already, and it has to be admitted that they don't try really hard.


For example, we have an IP camera that supports RTSP. Anyone who has ever tested the traffic with a Sharkwire cable will tell you that first there comes DESCRIBE, then PLAY, and then the traffic begins to pour directly via RTP or wrapped in the TCP channel for instance.

Dynamic CDN for Low Latency WebRTC Streaming with Stream Access Control

In the first part, we have deployed a simple dynamic CDN for broadcasting WebRTC streams to two continents and have proved on the example of a countdown timer that the latency in this type of CDN is actually low.


In the second part, we have incorporated dedicated servers into the CDN for performing the task of transcoding in order to provide good broadcast quality to our viewers based on the devices they use and the channel quality. In this manner, all published streams in our CDN are available to all the viewers.


Now, assume that a company is starting to introduce its monetization strategy where a number of streams should be available for free and the rest on a subscription basis. Or, for example, webinars for in-house staff training are broadcasted simultaneously, but each subsidiary has a separate stream, and disclosing the sales techniques used in Southeast Asia to the managers from CIS countries is undesirable.

In the first part we have deployed a simple dynamic CDN for broadcasting WebRTC streams to two continents and have proved on the example of a countdown timer that the latency in this kind of CDN is actually low.


However, besides low latency, it is important to provide good broadcast quality to users. After all, this is what they are paying for. In real life the channels between Edge servers and users can differ in bandwidth capacity and quality. For example, we are publishing a 720p stream at 2 Mbps, the user is playing it on an Android phone using 3G connection in an unstable signal reception area and the 360p maximum resolution that provides smooth picture at 400 Mbps is 360p.

Having analyzed earlier the capacity of standard server configurations in Digital Ocean in terms of WebRTC streaming, we have noticed that one server can cover up to 2000 viewers. In real life, cases when one server is insufficient are not uncommon.


Assume gambling amateurs in Germany are watching real-time horse races in Australia. Given that horse races are not only a sports game but also imply big gains on condition that field bets are made at the right time, the video has to be delivered with lowest possible latency.


Another example: A global corporation, one of FCMG market leaders with subsidiaries in Europe, Russia and Southeast Asia, is organizing sales manager training webinars with live streaming from the headquarters in the Mediterranean. The viewers must be able to see and hear the presenter in real time.

Millions of businesses exchange information on the internet and to interact with their target audience. This helps them make fast and secure transactions over the web. However, business goals can be achieved when the businesses are able to store all this data for the means of presenting quality output to the end users.

Simply put, in the development industry a web application (or “web app”) is more like a program that uses a web browser to handle the storage and retrieval of the information to present information to the users. This allows a user to interact with the company using the online forms, e-shopping carts, CMS, etc. Some more examples of web applications are online banking, online polls, online forums, online reservations, shopping cart, and interactive games.

Learning about web development is kind of like having too many things on a plate. This guide serves as a way to get your acquainted with the world of web app development.

When talking about "bad code" people almost certainly mean "complex code" among other popular problems. The thing about complexity is that it comes out of nowhere. One day you start your fairly simple project, the other day you find it in ruins. And no one knows how and when did it happen.


But, this ultimately happens for a reason! Code complexity enters your codebase in two possible ways: with big chunks and incremental additions. And people are bad at reviewing and finding both of them.

Open Graph protocol is a web standard originally developed by Facebook that turns any webpage into a graph object with title, description, image and so on. Even though there is no direct correlation between OG meta tags and improved SEO rankings, it still drives more traffic to your webpage by making it more “attractive” in social networks (Facebook, Twitter, Linkedin, etc).

An example of a link shared in Twitter that has «og:image» and «og:title».
