• Do you employ any tools for managing technical debt?

  - by Phil.Wheeler

  The site I work with on a day-to-day basis has its share of shortcomings and we often make design decisions to "get us by right now" with the intention of fixing those up later. I've found that making the time to actually go back and fix them, let alone remembering what the full list of to-do items is can be challenging at best. Can you recommend any tools, resources or tricks that help you effectively manage your technical debt?

• What's the best way to stop multiple instances of a Windows app being launched?

  - by John

  Many Windows apps (like Skype or MSN for instance) don't let you start multiple instances, rather trying to run it a 2nd time just leaves the existing version running. Is this typically done in some simple way - the start-menu shortcut is a 'wrapper' app around the main app - or is there some registry magic you can do to delegate the problem to Windows itself? Specifically dealing with Win32 here (unmanaged C++) but happy to hear more general solutions as long as they are workable on Windows XP or alter.

  - by London

  Maybe the title is not appropriate but I couldn't think of any other at this moment. My question is what is the difference between LinkedList and ArrayList or HashMap and THashMap . Is there a tree structure already for Java(ex:AVL,Black-white) or balanced or not balanced(linked list). If this kind of question is not appropriate for SO please let me know I will delete it. thank you

• PHP: Check if it has been one week since timestamp

  - by Rudi

  Hi guys, Let's assume: $time = '2010-05-17 02:49:30' // (retrieved from MySQL TIMESTAMP field) How do I do the following in PHP: 1) Check if it has been more than one week since this time has passed? 2) Assuming "false" on (1), find out how much more time until the one week mark, rounded to days and hours remaining. I know this is pretty straightforward, but it uses a very specific syntax. Having never played with time calculations before, I'd appreciate some guidance. Thanks!
