• Stairway to Database Design STEP 2: Domains, Constraints and Defaults

  A clear understanding of SQL Data Types and domains is a fundamental requirement for the Database Developer, but it is not elementary.

• Fixing a spelling mistake in a method name

  - by One Two Three

  One of the methods that I commonly use in our codebase is misspelled (and it predated me). This really irritates me not simply because it is mispelled but more importantly it makes me ALWAYS get the method name wrong the first time I type it (and then I have to remember "Oh, right, it should be mispelled to this...") I'm making a few changes around the original method. Should I take the opportunity to just rename the freaking method?

• How to restart Gnome Shell after a crash short of killing X?

  - by wintercorn

  How can I restart Gnome Shell after a crash? Alt+F2 and restart won't work as the prompt crashed with the shell. Since windows focus is gone along with the shell as well, I can't type gnome-shell --replace in a terminal, either. The Ctr+Alt+F1 command line can't open the X display. So I'm left with killing X, thus loosing all open applications. Is there a keyboard shortcut for restarting Gnome Shell?

  I installed Ubuntu with WUBI in Windows 7 64bit, and I had installed Mandriva 2011 with a disk.

• Finding "Stuff" In OUM

  - by Dave Burke

  One of the first questions people asked when they start using the Oracle Unified Method (OUM) is “how do I find X ?” Well of course no one is really looking for “X”!! but typically an OUM user might know the Task ID, or part of the Task Name, or maybe they just want to find out if there is any content within OUM that is related to a couple of keys words they have in their mind. Here are three quick tips I give people: 1. Open up one of the OUM Views, then click “Expand All”, and then use your Browser’s search function to locate a key Word. For example, Google Chrome or Internet Explorer: <CTRL> F, then type in a key Word, i.e. Architecture This is fast and easy option to use, but it only searches the current OUM page 2. Use the PDF view of OUM Open up one of the OUM Views, and then click the PDF View button located at the top of the View. Depending on your Browser’s settings, the PDF file will either open up in a new Window, or be saved to your local machine. In either case, once the PDF file is open, you can use the built in PDF search commands to search for key words across a large portion of the OUM Method Pack. This is great option for searching the entire Full Method View of OUM, including linked HTML pages, however the search will not included linked Documents, i.e. Word, Excel. 3. Use your operating systems file index to search for key words This is my favorite option, and one I use virtually every day. I happen to use Windows Search, but you could also use Google Desktop Search, of Finder on a MAC. All you need to do (on a Windows machine) is to make sure your local OUM folder structure is included in the Windows Index. Go to Control Panel, select Indexing Options, and ensure your OUM folder is included in the Index, i.e. C:/METHOD/OM40/OUM_5.6 Once your OUM folders are indexed, just open up Windows Search (or Google Desktop Search) and type in your key worlds, i.e. Unit Testing The reason I use this option the most is because the Search will take place across the entire content of the Indexed folders, included linked files. Happy searching!

• What methods of requirements elicitation are suitable when I do not have direct access to the user base?

  - by metadice

  I am working on an application to create invoices. There are some features that are required based on the type of the application and are common to all invoice applications. However, we still need to determine what unique needs the user base might have. We do not have direct access to the users to obtain requirements or user stories. What techniques are most suitable for eliciting high-quality requirements from users when direct or frequent access is not possible?

• WPF4 Unleashed - how does converting child elements work?

  - by Kapol

  In chapter 2 of the book WPF4 Unleashed the author shows an example of how XAML processes type conversion. He states that <SolidColorBrush>White</SolidColorBrush> is equivalent to <SolidColorBrush Color="White"/> , because a string can be converted into a SolidColorBrush object. But how is that enough? It doesn't make sense to me. How does XAML know to which property should the value White be assigned?
