  • Mysql / Django - Begin auto increment to 1

    - by ark
    Hi, I have a django script which loads data, the beginning of the script deletes all datas in database. So when I execute 1st time this script, the auto increment primary keys begin to 1 to 15 (if 15 objects) and if I want to reload data, I reexecute the script. My issue is when I execute it again, pks numbers begin to 16 (for 2nd launch), I would like each time auto_increment begins to 1, is it possible whitout regenerating tables structure each time ? Thanks

  • Application Profiling: Memory Usage

    - by Abs
    Hello all, I have switched on the Codeigniter profile (very useful) and I have noticed that a page of mine shows the memory used as: 2,405,496 bytes That's ~2MB and it's for one request - does it mean if 1000 users accessed this page at the same time, memory usage will be 2GB? Have I got my maths wrong or is there more to this than just multiplying two numbers? Thanks all for any help

  • How can I ignore .svn directories when using sloccount?

    - by digitala
    I'm trying to use sloccount from within hudson to gather statistics on our codebase, however by default sloccount collects information on all files, even those which are "hidden" (eg. .hideme). This means the statistics are skewed since they include numbers from files within the .svn directories. Is there any way I can tell sloccount to correctly ignore any files/directories which start with a .?

  • Flex bug?? Get messed up stacked ColumnChart with type="100%"

    - by Nir
    I am trying to do a stacked Column chart with type="100%" and a mixture of positive and negative values. When all the values are positive, is functions well, but when negative numbers come to the game, it looks totally messed up. When I also look at Adobe documentation (look here), I see the following code for stacked column chart involving negative numbers: <?xml version="1.0"?> <!-- charts/StackedNegative.mxml --> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script><![CDATA[ import mx.collections.ArrayCollection; [Bindable] public var expenses:ArrayCollection = new ArrayCollection([ {Month:"Jan", Profit:-2000, Expenses:-1500}, {Month:"Feb", Profit:1000, Expenses:-200}, {Month:"Mar", Profit:1500, Expenses:-500} ]); ]]></mx:Script> <mx:Panel title="Column Chart"> <mx:ColumnChart id="myChart" dataProvider="{expenses}" showDataTips="true"> <mx:horizontalAxis> <mx:CategoryAxis dataProvider="{expenses}" categoryField="Month" /> </mx:horizontalAxis> <mx:series> <mx:ColumnSet type="stacked" allowNegativeForStacked="true"> <mx:series> <mx:ColumnSeries xField="Month" yField="Profit" displayName="Profit" /> <mx:ColumnSeries xField="Month" yField="Expenses" displayName="Expenses" /> </mx:series> </mx:ColumnSet> </mx:series> </mx:ColumnChart> <mx:Legend dataProvider="{myChart}"/> </mx:Panel> </mx:Application> It works fine. But try to change: <mx:ColumnSet type="stacked" allowNegativeForStacked="true"> to: <mx:ColumnSet type="100%" allowNegativeForStacked="true"> and you'll see that it doesn't on January data, where both values are negative, the chart shows as if they are positive, and on the other two where one value is positive and the other is negative, it shows only the positive part as 100%... Isn't it a Flex Bug? I have my own case with such data and it behaves wrong the same way. I'd expect that if it has 800 stacked on -200, it will show 80% up and 20% down, totalling 100%. BTW: Using Flex 4, though these are all mx components. Thanks a lot and regards from Berlin, Germany, Nir.

    - by clyfe

  • if string is alphabetically greater than other string in objective

    - by Jonathan
    I'm trying to use an if statement to work out which of 2 strings comes first alphabetically. Like with numbers and greater and less than: if (1 < 2) { just with strings: if(@"ahello" < @"bhello") { Or would I have to have a string containing all the letters and then check the index of the first char in each string and see which index is greater, and the index that is less than the other comes first in the alphabet and then if they are equal move on to the next char and repeat?

  • Exact cin equivalent function in python

    - by gkt.pro
    Suppose user enter this string at terminal 123 456 456 //then hit enter How do I scan these three (could be more) numbers in different variables in python Could be something like this: for i in range(1,n) m[i]=#WHAT FUNCTION SHOULD I PUT HERE In c++ we can easily use cin>>m[i] inside above loop to scan the variables. If i use input() or raw_input() , they would scan whole line in single variable.

  • Accessing Subversion commit data externally

    - by gaoshan88
    I have need to access subversion data (commit messages, files updated, revision numbers, dates modified, author, etc.) externally. Is this something for some sort of subversion hook or is there a decent third party package for this or some other "best practice" way to approach accessing subversion data externally (and by external I mean from a php/ruby or python script... external to subversion itself)?
