From some time now the links for downloading project files in my blog are not working. This is because most of them are from dropbox and they for some reason changed their sharing policy and now all public links has been disabled and I must edit all the links one by one. Things get further complicated because I use URL shortening service (bit.ly), and long story short - it will take some time to fix all the links.
Update: September 08, 2017
Most of the links are now fixed.
