No such file or directory error with ruby tempfile and heroku cedar
Bit of a strange error had me puzzled, the app worked great on Bamboo but was erroring on cedar with: No such file or directory – /app/tmp/csv_export_120120806-2-1bnlu8h.csv.lock /app/vendor/ruby-1.9.3/lib/ruby/1.9.1/tempfile.rb:346:in `rmdir’ The actual line of code was this: temp_file = Tempfile.new([“csv_export”, ‘.csv’], Rails.root.join(‘tmp’) ) It turns out on Cedar the Rails tmp directory isn’t created by default […]

Mac OSX Tip: Mirror menubar to Dual Display / 2nd Monitor
Found this nifty program today ‘SecondBar‘ it creates an extra menubar on your 2nd monitor which means you don’t have to move your mouse across both screens to access a menu item. http://blog.boastr.net/?cat=1 NB: Currently your usual menubar icons aren’t copied across, however there are some nifty extras like enabling you to right-click the maximise […]
