How to generate an SSH Key to clone a Git repository using the SSH protocol

When you clone a remote repository using HTTPS, Git will prompt you for your username and password during the authentication process, on the other hand, when using SSH, Git uses your SSH key to authenticate, which means you don't need to send your credentials over the network. 

Furthermore, SSH is a more secure method for cloning repositories, and working with the Git repos, as only the machines with the key file on disk can access these repositories. Even if the SSH key file was to be stolen, it wouldn't give access to the account itself (unlike the credentials) and can be easily revoked. 

Creating an SSH Key

To generate a new SSH key, open up your terminal app, i.e., Git Bash, and type the following;

AzureAD+NurhakKaya@WAT607 MINGW64 /

$ cd .ssh/

AzureAD+NurhakKaya@WAT607 MINGW64 /.ssh

$ ls

id_rsa  id_rsa.pub

AzureAD+NurhakKaya@WAT607 MINGW64 /.ssh

$ ssh-keygen -t rsa -b 4096 -C "[email protected]"

Generating public/private rsa key pair.

Enter file in which to save the key (/c/Users/NurhakKaya/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /c/Users/NurhakKaya/.ssh/id_rsa

Your public key has been saved in /c/Users/NurhakKaya/.ssh/id_rsa.pub

The key fingerprint is:

SHA256:23Ur……………………………Ic1CdEJGL4ipg [email protected]

The key's randomart image is:

+---[RSA 4096]----+

|ooo+             |

|+ +        . .   |

| ı o .    . o    |

|. . o  . o . .   |

|o+  . o S = X +  |

|E -. + . * O O o |

|o.4   + + + o = .|

| o   . o +   o . |

|        +....    |

+----[SHA256]-----+

AzureAD+NurhakKaya@WAT607 MINGW64 /.ssh

$

Using the new SSH Key to Clone a Repo, using the SSH URL

You should now see the newly generated SSH files under your .ssh folder. Open the id_rsa.pub file and copy its value to add your new SSH Key, i.e., on Azure DevOps. Finally, copy the SSH URL for your repo and clone it.

How to fix Umbraco v9 "Boot Failed : Umbraco failed to boot, if you are the owner of the website please see the log file for more details." error

If you have started working with Umbraco v9 and done your first Azure deployment to one of your testing environments, there is a possibility that you might see the following "Boot Failed" error. Error: Checking the logs In order to understand the problem, you should check the Umbarco log file.  The default location for this file is umbraco/Logs and this file contains the Machine name, along with the date information. You can reach this file via Azure's Kudu Service  or alternatively, you can get download your Azure App Service's publish profile and connect your App Service via an FTP application, i.e. FileZilla.

Please be aware, as most things with Umbraco, logging is also customizable, so you can either use the default Umbraco logging which is Micros

How to use JQuery Ajax Methods for Async ASP.NET MVC Action Methods

Making repeatedly calls to async methods can be a nightmare. In this case, it makes sense to use 2 ajax methods, instead of one. Here is a simple solution to overcome this problem. See that  ajaxcalls   is emptied after the success response for the first ajax call and then the second ajax method is used to make one single call to the async action method. Hope it helps. View: @section Scripts{     < script type ="text/javascript">         var smartDebitObject = new Object();         smartDebitObject.MembershipNumber = $( "#MembershipNumber" ).val();         smartDebitObject.ProfileId = $( "#ProfileId" ).val();         smartDebitObject.FirstName = $( "#FirstName" ).val();         smartDebitObject.LastName = $( "#LastName" ).val();         smartDebitObject.AddressLine1 = $( "#AddressLine1" ).val();         smartDebitObject.Postcode = $( "#Postcode" ).val();         smartDebitObject

How to fix Umbraco CMS Build Error NU1104: Unable to find project '..\Umbraco-CMS\tools\Umbraco.Core\Umbraco.Core.csproj'.

Yesterday during an online meeting , I was talking about how to contribute to Umbraco CMS . As part of this talk, in order to set up my local Umbraco CMS project ,  I cloned the latest Umbraco.CMS code to my local machine, but when I built it I saw the following error: Error NU1104 Unable to find project ' D : \git \repos \Umbraco -CMS \tools \Umbraco .Core \Umbraco .Core .csproj ' . Check that the project reference is valid and that the project file exists . Umbraco .JsonSchema D : \git \repos \Umbraco -CMS \tools \Umbraco .JsonSchema \Umbraco .JsonSchema .csproj I was surprised to see this error as I did the exact same thing a couple of days ago and saw no problems.  After trying a few things, I checked the Umbraco.JsonSchema project's project references and realised that Umbraco.Core project reference was broken.  After removing Umbraco.Core from the Umbraco.JsonSchema and adding it again fixed the problem and I could then do my local database setup as normal.
