Failed to resolve: com.android.support:cardview-v7:26.0.0 android and similar

Recently I updated my android SDK tools and I started getting this error
Failed to resolve: com.android.support:cardview-v7:26.0.0 android
Solution to this or any other similar error is to add maven end point in your build.gradle file
allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com'
        }

    }

Decoding JPEG image file using libavcodec

I got a chance to work on a video encoding application that decodes series of jpeg files and convert them into ogg theora video file. I used the infamous libavcodec library that is used in FFMPEG . I decided to write blog posts explaining how I decode jpeg images and convert them into ogg video file. This is the first part and in this I will explain how to decode jpeg images using libavcodec. To learn how to write decoded images as a ogg video file please read http://random-stuff-mine.blogspot.com/2017/07/encoding-raw-images-to-ogg-theora-video.html Before reading this blog post you must be aware of using and setting up libavcodec. I highly recommend this tutorial to get basics of using libavcodec http://www.ffmpeg.org/doxygen/0.6/api-example_8c-source.html Allocating input format context We will first allocate input format for reading the file. We will use avformat_open_input function that will allocate AVFormatContext structure passed to it , the function detects input typ

CryptographicException: An error occurred while trying to encrypt the provided data. Refer to the inner exception for more information

I created a new Blazor Server app in Visual Studio 2019 and tried to run it. But I was getting this error CryptographicException: An error occurred while trying to encrypt the provided data. Refer to the inner exception for more information. I couldn't find any reason or solution to this problem. I tried creating the project multiple times but same error. I created a new .Net Core Web App and added a new razor component and included that component in a razor page (cshtml file) like this @(await Html.RenderComponentAsync<GeofenceWork>(RenderMode.ServerPrerendered)) and <component type="typeof(GeofenceWork)" render-mode="serverprerendered" /> As soon as I navigate to this page that has component added I got the same error: CryptographicException: An error occurred while trying to encrypt the provided data. Refer to the inner exception for more information. This was very frustrating. After hours of trying and searching I figured out the solution. 

Multithreaded C# TCP server to handle multiple clients

I decided to write a minimal multithreaded TCP based server as a blog post. Following class can serve as a skeleton for any small or large scale multithreaded TCP socket server. It do not contain much error handling , it is only to give an idea that how multithreaded server works and how it can process multiple clients using threading. using System; using System.Text; using System.Net; using System.Net.Sockets; using System.Threading; using System.Collections.Generic; namespace RandomStuffMine { public class MTServer {     public int Port{get;set;}     public Socket ServerSocket{get;set;}     private List<Client> Clients=new List<Client>();     private bool runServer=true;     public MTServer(int port)     {         Port=port;         ServerSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);     }     public void Start()     {         Thread thr=new Thread(new ThreadStart(StartServer));         thr.IsBackground=t
