If you've ever developed a non-trivial Web application, you know that development complexity is increased by the fact that Web browsers allow users to follow arbitrary navigation paths through the application. No matter where the user navigates, the onus is on you, the developer, to keep track of the possible interactions and ensure that your application works correctly. While the traditional MVC approach does allow you to handle these cases, there are other options available to help resolve application complexity. Developer and frequent developerWorks contributor Abhijit Belapurkar walks you through a continuations-based alternative that could simplify your Web application development efforts.
The best thing you can do for your servers and the programs you host to buy your own copy of Thomas A. Limoncelli and Christine Hogan's The Practice of System and Network Administration. This new book, though aimed at administrators, is full of valuable lessons for developers, too. While it mentions Linux only once in almost 800 pages -- and obliquely at that -- the principles it explains will help make more sense of your work every day.

Many applications use HTML for reporting and online help, among other things. Embedding a Web browser in your application eliminates the need to worry about which browser a client uses to view your pages, and also allows you to create custom tags that tie the HTML page back to your application. For example, for the help system in an IDE, a user could browse a function reference where you have created custom tags, and when the user clicks on the function name, the function call could be inserted into the user's code.
Having multiple Linux installations to work with allows you to easily test different libraries with the same program, watch how your program interacts with others, or just tweak a parameter here or there to see what happens. This comes in handy for development and testing -- as well as for customer support. You say that you don't have oodles of boxes to work with? No worries -- installing multiple instances of Linux on a single box is a cinch, as you'll soon discover in this tip from IBM interns Chuks Onwuneme and Farhan Khawaja.
