A few days ago while updating the backup file after correcting an error in the original file, a glitch occurred that fried both the original file for the 7/23/16 edition of TECH Dozens and the backup file. Reconstructing the original would take an excessive amount of time, so the 7/23/16 edition is lost. Our new backup procedure will preclude this kind of total loss from reoccurring because we now make backups to the backups. I apologize for this inconvenience.
