we can run that WindowsIdentity.GetCurrent() returns application pool account

SPSecurity.RunWithElevatedPrivileges(delegate

{

    var context = HttpContext.Current;

    HttpContext.Current = new HttpContext(new HttpRequest(string.Empty, SPContext.Current.Site.Url, string.Empty), new HttpResponse(new StringWriter()));

    HttpContext.Current.User = new GenericPrincipal(WindowsIdentity.GetCurrent(), new string[0]);

    var manager = new UserProfileManager(SPServiceContext.GetContext(HttpContext.Current));

    var profile = manager.GetUserProfile(@"domain\name");

    var value = profile["my_property"].Value;

    HttpContext.Current = context;

});

Getting all user profiles within SharePoint tenant using SharePoint Online CSOM API

• retrieve all the users in tenant (Get-MsolUser cmdlet)
• iterate users and utilize SharePoint User Profiles CSOM API to retrieve user profile

function Get-SPOContext([string]$Url,[string]$UserName,[string]$Password)

{

   $context = New-Object Microsoft.SharePoint.Client.ClientContext($Url)

   $context.Credentials = Get-SPOCredentials -UserName $UserName -Password $Password

   return $context

}

function Get-SPOCredentials([string]$UserName,[string]$Password)

{

   $SecurePassword = $Password | ConvertTo-SecureString -AsPlainText -Force

   return New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($UserName, $SecurePassword)

}

function Print-UserProfileInfo([Microsoft.SharePoint.Client.UserProfiles.PeopleManager]$PeopleManager,[string]$AccountName){

   $ctx = $PeopleManager.Context

   $accountName = "i:0#.f|membership|" + $AccountName  #claim format  

   $userProfile = $PeopleManager.GetPropertiesFor($AccountName)

   $ctx.Load($userProfile)

   $ctx.ExecuteQuery()

   Write-Host $userProfile.PersonalUrl

}

  SharePoint 2013 Client Object Model now has a class called SharePointOnlineCredentials

using (ClientContext Ctx = new ClientContext("http://devprasad007-admin.sharepoint.com"))  

{  

    SecureString passWord = new SecureString();

    Ctx.Credentials = new SharePointOnlineCredentials("ramp@devprasad007.onmicrosoft.com", passWord);

    Web web = Ctx.Web;

    Ctx.Load(web);

    Ctx.ExecuteQuery();

    Console.WriteLine(web.Title);

    Console.ReadLine();

} 

Break role inheritance for a List object and grant Full Control permissions for a current user

 var listTitle = 'Documents';

var spCtx = SP.ClientContext.get_current();

var list = spCtx.get_web().get_lists().getByTitle(listTitle);   

spCtx.load(list,'HasUniqueRoleAssignments'); 

spCtx.executeQueryAsync(

   function(){

      var hasUniqueAssgns = list.get_hasUniqueRoleAssignments();

      if(!hasUniqueAssgns) {

         list.breakRoleInheritance(false, true);

         spCtx.executeQueryAsync(

            function(){

                console.log('Success');

            }, 

            function(sender,args){

               console.log(args.get_message());    

            }

         );
