Since 1998, DevX has helped people start businesses, build websites, and provide enterprise technology to people globally. Interviewing the likes of Microsoft’s co-founder, Steve Ballmer, the publication brings comprehensive, reliable, and accessible insights to the Internet.
Debugging is an art that every successful programmer needs to master sooner rather than later. The sad truth is that program bugs appear almost as soon as you start coding.

‘ ShellSort. A compact routine that sorts data in place (no extra memory ‘ needed) and runs in O(N (log N)^2) time. Not stable (does not preserve ‘ original order
‘ QuickSort. QuickSort, CombSort and ShellSort all exploit the principle of ‘ exchanging keys that are far apart in the list rather than adjacent. ‘ QuickSort does this most elegantly
‘ MSD RadixSort. No sort based on comparisons can be faster than O(N log N). ‘ RadixSort makes no comparisons and can therefore achieve O(N) behavior. To ‘ do this,
‘ InsertionSort. A simple routine with minimal overhead. Should never be used ‘ to sort long lists because of its O(N^2) behavior,’ but is the method of choice for sorting
‘ Ternary QuickSort. See the summary of QuickSort for background before ‘ reading this one. Ternary QuickSort (also called MultiKey QuickSort) differs ‘ from the original QuickSort by examining keys
‘ 2/4/03. The previous version of ShuttleMergeSort failed on very short lists. ‘ The code below corrects the problem and eliminates a couple of unnecessary ‘ variables. Sorting times for
‘ SelectionSort. Short, simple and sloooow. This is another O(N^2) sort that ‘ should never be used on long lists. Like InsertionSort,’ it needs no extra memory (in place) and

Learning XML requires a basic understanding of WWW, HTML, and Web scripting languages such as JavaScript or VBScript. Many of the following articles were written around the time that XML
Learning how to use Web services takes for granted a solid foundation in XML, mainly because the attendant technologies used in Web services are XML-based (such as SOAP and WDDI).
Becoming familiar with the basics of each of these languages goes a long way to ensuring well-rounded development capabilities. While one language may seem more daunting than another, we think
