If you get a "wrong number of arguments(2 for 1)" in the stale_session_check method when running your jruby ruby on rails application, the problem may be your sessions. Clear the sessions and delete all rows from the sessions database table if you are using one. Then add to environment.rb:
config.action_controller.session = { :session_key => "_myapp_session", :secret => "some secret phrase of at least 30 characters" }
The code has to be inside the Rails::Initializer.run do |config| block.
The following Powershell script will convert a batch of JPEG files to TIFF format: #This Code is released under MIT license [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing") $files_folder = 'C:\path-where-your-jpg-files-are\' $pdfs = get-childitem $files_folder -recurse | where {$_.Extension -match "jpg"} foreach($pdf in $pdfs) { $picture = [System.Drawing.Bitmap]::FromFile( $pdf.FullName ) $tiff = $pdf.FullName.replace('.PDF','').replace('.pdf','').replace('.jpg','').replace('.JPG','') + '.tiff' $picture.Save($tiff) }
