  • How to handle status columns in designing tables

    - by altsyset
    How to handle multiple statuses for a table entry, for example an item table may have an active, inactive, fast moving, and/or batch statuses. And I wanted to handle them in single column with VARCHAR type. Also I might set each of those attributes as a boolean with different columns. But I am not sure what consequences this might lead to. So if you have experienced such situations which one would be the best way to handle it?

  • Libreoffice 3.5 won't launch from Desktop Shortcut: Ubuntu 11.10 Unity

    - by Aivard
    I've upgraded my Libreoffice to the recent 3.5 version. Before, I was using LO 3.45 and it had no problems on launching from the Desktop Shortcut. Anyways, when I upgraded and tried to create a shortcut from the launcher it reported this, "The application launcher "libreoffice3.5-base.desktop" has not been marked as trusted. If you do not know the source of this file, launching it may be unsafe." Any ideas of fixing this. Thanks in advance: Regards

  • while(true) and loop-breaking - anti-pattern?

    - by KeithS
    Consider the following code: public void doSomething(int input) { while(true) { TransformInSomeWay(input); if(ProcessingComplete(input)) break; DoSomethingElseTo(input); } } Assume that this process involves a finite but input-dependent number of steps; the loop is designed to terminate on its own as a result of the algorithm, and is not designed to run indefinitely (until cancelled by an outside event). Because the test to see if the loop should end is in the middle of a logical set of steps, the while loop itself currently doesn't check anything meaningful; the check is instead performed at the "proper" place within the conceptual algorithm. I was told that this is bad code, because it is more bug-prone due to the ending condition not being checked by the loop structure. It's more difficult to figure out how you'd exit the loop, and could invite bugs as the breaking condition might be bypassed or omitted accidentally given future changes. Now, the code could be structured as follows: public void doSomething(int input) { TransformInSomeWay(input); while(!ProcessingComplete(input)) { DoSomethingElseTo(input); TransformInSomeWay(input); } } However, this duplicates a call to a method in code, violating DRY; if TransformInSomeWay were later replaced with some other method, both calls would have to be found and changed (and the fact that there are two may be less obvious in a more complex piece of code). You could also write it like: public void doSomething(int input) { var complete = false; while(!complete) { TransformInSomeWay(input); complete = ProcessingComplete(input); if(!complete) { DoSomethingElseTo(input); } } } ... but you now have a variable whose only purpose is to shift the condition-checking to the loop structure, and also has to be checked multiple times to provide the same behavior as the original logic. For my part, I say that given the algorithm this code implements in the real world, the original code is the most readable. If you were going through it yourself, this is the way you'd think about it, and so it would be intuitive to people familiar with the algorithm. So, which is "better"? is it better to give the responsibility of condition checking to the while loop by structuring the logic around the loop? Or is it better to structure the logic in a "natural" way as indicated by requirements or a conceptual description of the algorithm, even though that may mean bypassing the loop's built-in capabilities?

  • Control Parameters and DropDownList Text

    - by Bunch
    This is something that I rarely need to do, grab a DropDownList’s selected item’s text for use in a datasource’s ControlParameter. To allow for this use SelectedItem.Text instead of the more common SelectedValue for the PropertyName. <asp:ControlParameter ControlID="ddlStuff" Name="stuffName" Type="String" PropertyName="SelectedItem.Text" /> The reason for using this is for text comparison. On rare occasions you may need to check the text against a list where the SelectedValue just does not help. Technorati Tags: ASP.Net

    Every emerging technology generation seems to result in a battle of platforms and ideologies - a war between companies for the hearts, minds, dollars and loyalty of consumers for their system of choice.

  • Wink and Grow Rich Online, a SEO Perspective

    There are thousands of online businesses making money, and even fewer online businesses creating wealth. The "difference" could be the reason why wealth seems to elude you no matter how hard you are working on making money. The irony is that if you are running after money, you may make some, and lose some. However, if you are focused on creating wealth, you will find that money will find its way to you, and what you build will keep growing in "value" with each passing day.
