how to start two threads (almost) simultaneously?

I have this block in rufus

def download(log_message)
  $logger.info(log_message)
  download_all_from_config()
end

scheduler.in '5s' do
  first = Thread.new(download("starting cron job (in 5s mode)"))
  sleep(55)
  second = Thread.new(download("starting 2nd cron job (in 5s mode)"))
  first.join
  second.join
end

and what I want is to run download_all_from_config() function twice almost simultaneously. This function is downloading big files so I do not want to wait till the fist one finishes. I thought I would use threads but I cannot make it work.

Could someone suggest how to run download_all_from_config() twice so it starts almost simultaneously?

You need to call Thread.new with a block. i.e instead of Thread.new(...) you need either

Thread.new { ... }

or

Thread.new do
  ...
end
