We all have heard of missiles blowing up in midair because of the wrong unit was used in calculating the trajectory or bank software that misplaced millions of dollars because of a decimal place. It might not compare against blowing up a multi-million dollar missile but here are some of the worst software bugs I’ve seen in projects where I’ve worked.<\/p>\n
Shift + O Short Cut – I once worked on a software application where one of the engineers developed a screen search functionality that would find the UI screen by name or feature. Needless to say the modal pop-up dialog for this search feature popped up when the user hit the Shift + O keys. This feature was developed by the engineer on his own initiative, so you can imagine everyone’s surprised when we couldn’t even type a capital o without this thing popping up.<\/p>\n
Exposing Regular Expressions – In another project we developed micro expression language which was used and exposed at the application level to users. In one situation, a user reported a error when he wanted to replace a variable place holder with a dollar amount. It seems that when he called the expression language replaceall(“AMOUNT_VALUE”, “$0.00”) the got back the value of AMOUNT_VALUE.00. This problem was caused because we used Java Regular Expressions feature of the String class and $0 expression is a special value in the Java RegEx. This was like a Regular Expression Injection<\/b> bug.<\/p>\n
Localization and Internationalization – In the same project we had a problem with displaying the correct currency symbol used in a financial account statement. There is a big difference between $100 and \u00e2\u201a\u00ac100. Account holders are not happy to know that their \u00e2\u201a\u00ac100 are now worth $100.<\/p>\n
Cut\/Copy\/Paste Does Not Work – I have seen way too many Java\/Swing application where some component does not have proper support for cut, copy, or paste. When you cut from a Java application and paste to say Notepad you get a stringified Java object.<\/p>\n
Textarea Size Limit – When filling online forms, the one bug that just kills me is where a textarea has a size limit not shown and you spend time typing a long response which will be either truncated, lost, or rejected on submit.<\/p>\n","protected":false},"excerpt":{"rendered":"
