6 August 2012 by , No Comments

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 =[“csv_export”, ‘.csv’], Rails.root.join(‘tmp’) ) It turns out on Cedar the Rails tmp directory isn’t created by default […]

Can’t believe I didn’t notice this before; after typing in a few letters of the site you are looking for rather than pressing the down arrow key, you can just press Tab to highlight the next item in the selection of sites (and Shift-Tab to go backwards).  Yey for keeping your fingers on the home […]

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.
