Cool stuff in .NET 4.0: System.Threading.Tasks.TaskScheduler

private void Save()

{

    System.Threading.Tasks.TaskScheduler uiScheduler = System.Threading.Tasks.TaskScheduler.FromCurrentSynchronizationContext();

    System.Threading.Tasks.Task<ErrorEnum>.Factory.StartNew(() =>

    {

        ErrorEnum callResult = ErrorEnum.OK;

        try

        {

            IsIdle = false;

            callResult = (ErrorEnum)DataContext.DomainRepository.SaveDomain(_domain);

            if (callResult != ErrorEnum.OK)

            {

                // If remote saving fails, rollback all the changes

                Rollback();

            }

            else

            {

                // If remote saving succeeds, save changes to local db

                SaveChangesToLocalDB();

            }

            return callResult;

        }

        catch (Exception ex)

        {

            LogManager.AddCMEventLog("DomainSettingsViewModel.Save", ex);

            // If anything goes wrong, rollback all the changes

            return ErrorEnum.LocalFatalAnonymousError;

        }

        finally

        {

            IsIdle = true;

        }

    }).ContinueWith(task => ShowResult(task.Result), uiScheduler);

}




This running tasks in background thread, then call UI thread to execute the ShowResult() function, Just like UIDispatcher

perl send email cgi

Lots of tutorials about sending email with perl depend on some uncommon libs.
There is a common way to do so:

use Net::SMTP::SSL;


sub send_mail {
    my $to      = $_[0];
    my $subject = $_[1];
    my $body    = $_[2];

perl session cgi

http://search.cpan.org/dist/CGI-Session/lib/CGI/Session/Tutorial.pm


$session = CGI::Session->load() or die CGI::Session->errstr;
if ( $session->is_expired ) {
    die "Your session expired. Please refresh your browser to re-start your session";
}
if ( $session->is_empty ) {
    $session = $session->new();
}

print $session->header();

#save into session

$session->param('username',$username);

#read from session

$variable = $session->param('username');
