* Rails is opinionated software. It makes the assumption that there is a "best" way to do things, and it's designed to encourage that way - and in some cases to discourage alternatives. If you learn "The Rails Way" you'll probably discover a tremendous increase in productivity. If you persist in bringing old habits from other languages to your Rails development, and trying to use patterns you learned elsewhere, you may have a less happy experience. * Don't Repeat Yourself: DRY is a principle of software development which states that "Every piece of knowledge must have a single, unambiguous, authoritative representation within a system." By not writing the same information over and over again, our code is more maintainable, more extensible, and less buggy. * Convention Over Configuration: Rails has opinions about the best way to do many things in a web application, and defaults to this set of conventions, rather than require that you specify every minutiae through endless configuration files.

* VB Watch Profiler lets you measure execution speed. See what procedures are the slowest ones, and which lines or loops are taking up most of the time. Or measure execution times before and after your enhancements. * No more mysterious error messages and crashes! No more yelling users! Find bugs the easy way. VB Watch adds advanced error handlers to your code with a few clicks, keeping your existing handlers fully enabled. * Error messages can include: error description, procedure name, line number, parameter and variable values, object properties, call stack, screenshot, run-time library versions, and even execution trace procedure-by-procedure, line-by-line. * VB Watch Debugger allows remote debugging at client site via TCP/IP. * The Console works together with Profiler, Protector and Debugger. Run the Console to instrument one or more projects in a batch. You can also call the console from a batch file to add error handling in a fully automated way each time right before you release your program.
