  • pitfalls with mixing storage engines in mysql with django?

    - by Dave Orr
    I'm running a django system over mysql in amazon's cloud, and the database default is innodb. But now I want to put a fulltext index on a couple of tables for searching, which evidently requires myisam. The obvious solution is to just tell mysql to ALTER TABLE to myisam, but are there going to be any issues with that? One that comes to mind is that I'll have to remember to do that any time I build a new version of the database, which should theoretically be rare, but there doesn't seem to be a way to tell django to please set the storage engine at the table level. I guess I could write a migration (we use south). Any other things I might be missing? What could possibly go wrong?

  • How do you manage web navigation info in your application?

    - by Dave
    I’m building an application where different users will have different menu items available to them depending on what they’ve paid for. There will also be multiple levels to the menu hierarchy. What’s the best approach to this problem? I’m assuming I need a database table that represents the menu hierarchy, including the parent-child relationships of the nodes in the navigation as well as the sorting of the items. Then another table which I use to manage whether a user is authorized to access a particular item in that table. When I render the view, I’d reference the menus, and the access rights of the user to output the menu, and I’d also need a function to check that same authorization from each controller in case a user manually types in a URL of a controller they’re not supposed to have access to. Is this the right approach? Any suggestions for caching this to prevent the constant look-ups of this type of info? I’m open to any suggestions on how you may have approached this type of requirement.

  • A new MEF error I've not seen before -- "The export is not assignable to type..."

    - by Dave
    I was very surprised to get this error today, as it's one that I've never encountered before. Everything in the code looked okay, so I did some searches. The previous questions and their respective answers didn't help. This one was solved when the poster made sure his assembly references were consistent. I don't have this issue right now because I'm currently referencing another project in my solution. This one was solved when the poster was instructed to use ImportMany, but I am already using it (I think properly, too) to try to load multiple plugins This one was solved when the poster realized that there was a platform target mismatch. I've already gone through my projects to ensure that everything targets x86. So here's what I am trying to do. I have a plugin that owns a connection to a device. I might also need to be able to share that connection with another plugin. I decided that the cleanest way to do this was to create an interface that would allow the slave plugin to request its own connection to the device. Let's just call it IConnectionSharer. If the slave plugin does not need to borrow this connection and has its own, then it should use its own implementation of IConnectionSharer to connect to the device. My "master" plugin (the one that owns the connection to the device) implements IConnectionSharer. It also exports this via ExportAttribute. My "slave" plugin assembly defines a class that also implements and exports IConnectionSharer. When the application loads, the intent is for my slave plugin, via MEF, to enumerate all IConnectionSharers and store them in an IEnumerable<IConnectionSharer>. It does so like this: [ImportMany] public IEnumerable<IConnectionSharer> AllSharedConnections { get; set; } But during part composition, I get the error the export 'Company.MasterPlugin (ContractName="IConnectionSharer")' is not assignable to type 'IConnectionSharer'. The error message itself seems clear enough -- it's as if MEF thinks my master plugin doesn't inherit from IConnectionSharer... but it does! Can anyone suggest further debugging strategies? I'm going to start the painful process of single stepping through the MEF source.

  • JQuery cycle plugin + PNG overlay + Image alt text as title conflict

    - by Dave
    I am trying to achive the following: Create an image gallery using the JQuery Cycle plugin that shows images with titles (taken from the alt text) Each image has a PNG absolutley posiioned over the top to achieve rounded corners effect Here's my gallery HTML: <div id="slideshow" class="pics"> <div class="photo-container" > <img src="/path/to/image" alt="alt text as title" /> <img class="mask" src="path/to/mask" /> </div> </div><!-- /slideshow --> <div id="title"></div> Here's my Jquery gallery function: $(function() { $('#slideshow').after('<div id="nav" class="nav"><span style="margin: 0 5px 0 30px;">next image</span>').cycle({ fx: 'fade', timeout: 0, cleartypeNoBg: true, pager: '#nav', next: '#slideshow', before: onBefore }); function onBefore() { $('#title').html(this.alt); } $('#nav a').after('<span>&gt;</span>') }); </script> Here is my CSS that handles the mask: .photo-container { position: relative; display: block; overflow:hidden; border: none; } img.mask { position: absolute; top: 0; left: 0; overflow:hidden; border: none; } The above does not output the alt text into the "title" div. When I remove the mask, it works: <div id="slideshow" class="pics"> <img src="/path/to/image" alt="alt text as title" /> </div><!-- /slideshow --> <div id="title"></div> Any ideas why the additonal div / image is casuing the title to not display? Thank you

  • SSIS Permissions issue

    - by Dave
    Hi All, How can we set permissions for users to only allow them to download SSIS packages from the production server and but deny them permissions to run any package in the Server. http://msdn.microsoft.com/en-us/library/ms141053(SQL.90).aspx If i assign users to any of the DB roles db_dtsadmin, db_dtsltduser, and db_dtsoperator they will automatically have permission to run the package. Appreciate your inputs. Thanks!

  • Python - Memory Leak

    - by Dave
    I'm working on solving a memory leak in my Python application. Here's the thing - it really only appears to happen on Windows Server 2008 (not R2) but not earlier versions of Windows, and it also doesn't look like it's happening on Linux (although I haven't done nearly as much testing on Linux). To troubleshoot it, I set up debugging on the garbage collector: gc.set_debug(gc.DEBUG_UNCOLLECTABLE | gc.DEBUG_INSTANCES | gc.DEBUG_OBJECTS) Then, periodically, I log the contents of gc.garbage. Thing is, gc.garbage is always empty, yet my memory usage goes up and up and up. Very puzzling.

  • Problems with my JS array undefined x 7

    - by Dave
    I have an array im trying to loop through to create a new type of array specific to my current page. My array looks like this: //$_SESSION['data'] = Array ( [0] => 1 [1] => 0 [2] => Tom [8] => 1 [4] => 1 [5] => Array ( [7] => Array ( [0] => Andrew [1] => 1 [2] => 1 [4] => 0 [5] => avatar.jpg [6] => 1 ) ) [6] => Array ( [0] => 1 [1] => 2 ) ) So in my JS file i have this: var stats = <? echo $_SESSION['data'][5]); ?> ; //this is the array my_data = new Array(); for(var key in stats){ if(key in my_data){} else { //prevent double entry my_data[key] = new Array(); my_data[key][0] = stats[key][6]; my_data[key][1] = stats[key][5]; my_data[key][2] = stats[key][2]; my_data[key][3] = stats[key][0]; } } console.log(my_data); Now in console.log i get this : [undefined × 7, Array[4] 0: "1" 1: "avatar.jpg" 2: "1" 3: "Andrew" length: 4 __proto__: Array[0] ] I'm wondering why it is saying undefined x7?

  • Need Help Loading and Manipulating Bitmap Data

    - by Dave
    Using VB6, I need to load a bitmap image and subsequently manipulate some of its data - specifically, I want to rotate a section within the image, and in the end keep the image intact with the rotated section. How do I (1) find out where an image gets loaded into memory (a physical address), and (2) in what format is it stored, a 1-D array, 2-D array, or what? Maybe you can even suggest a better way to do this. Thanks.

  • Help me make a jquery AJAXed divs' links work like an iframe.

    - by Dave
    I want to make a few divs on the same page work similar to iframes. Each will load a URL which contains links. When you click on those links I want an AJAX request to go out and replace the div's html with new html from the page of the clicked link. It will be very similar to surfing a page inside an iframe. Here is my code to initially load the divs (this code works): onload: $.ajax({ url: "http://www.foo.com/videos.php", cache: false, success: function(html){ $("#HowToVideos").replaceWith(html); } }); $.ajax({ url: "http://www.foo.com/projects.php", cache: false, success: function(html){ $("#HowToProjects").replaceWith(html); } }); This is a sample of code that I'm not quite sure how to implement but explains the concept. Could I get some help with some selectors(surround in ?'s) and or let me know what is the correct way of doing this? I also want to display a loading icon, which I need to know where the right place to place the function is. $(".ajaxarea a").click(function(){ var linksURL = this.href; // var ParentingAjaxArea = $(this).closest(".ajaxarea");; $.ajax({ url: linksURL, cache: false, success: function(html){ $(ParentingAjaxArea).replaceWith(html); } }); return false; }); $(".ajaxarea").ajaxStart(function(){ // show loading icon });

  • ORB forwards to a wrong location

    - by dave-keiture
    I have an orbd started at a virtual host (with the IP A), with some remote object registered. Box that hosts virual boxes has IP B. When client tries to connect to the ORB at A to acquire the NamingContext, ORB replies with a LocationForward message poiniting to host B and port 1049 (like if another ORB would be started at that host). NamingContext is returned successfully, but obviously I'm not able to acqure the objects, registered at the NamingContext (at ORB hosted at A) by the name. Could anyone please explain what's happening? How can I access the orb hosted at A remotely? Thanks in advance.

    I'm using Spring 3.1.1.RELEASE. Using the form:select tag, how do I specify which option should be selected? I want the first one to be selected, but when I put <form:select path="parentOrganization"> <form:option value="" label="Select an Org Type or Parent Org" /> <form:options items="${orgTypesWoParents}" itemValue="id" itemLabel="description" /> <form:option value="" label="=======================" /> </form:select> the last one is selected. I want to preserve the order of how everything is displayed, which is why I've arranged things in this way.

  • Int - number too large. How to get program to fail?

    - by Dave
    Hi Problem: How do you get a program to fail if a number goes beyond the bounds of its type? This code below gives the wrong answer for sum of primes under 2 million as I'd used an int instead of a long. [TestMethod] public void CalculateTheSumOfPrimesBelow2million() { int result = PrimeTester.calculateTheSumOfPrimesBelow(2000000); // 2million Assert.AreEqual(1, result); // 1,179,908,154 .. this was what I got with an int... // correct answer was 142,913,828,922 with a long } public static class PrimeTester { public static int calculateTheSumOfPrimesBelow(int maxPrimeBelow) { // we know 2 is a prime number int sumOfPrimes = 2; int currentNumberBeingTested = 3; while (currentNumberBeingTested < maxPrimeBelow) { double squareRootOfNumberBeingTested = (double)Math.Sqrt(currentNumberBeingTested); bool isPrime = true; for (int i = 2; i <= squareRootOfNumberBeingTested; i++) { if (currentNumberBeingTested % i == 0) { isPrime = false; break; } } if (isPrime) sumOfPrimes += currentNumberBeingTested; currentNumberBeingTested += 2; // as we don't want to test even numbers } return sumOfPrimes; } }

  • Python HTTPSConnection.close() does not appear to close the connection?

    - by Dave
    I'm not sure if this is a bug or if I'm just doing something wrong. If I were to do an HTTP connection like this: import httplib http_connection = httplib.HTTPConnection("192.168.192.196") http_connection.request("GET", "/") http_connection.sock.settimeout(20) response = http_connection.getresponse() data = response.read() http_connection.close() Then at a DOS prompt, I do this: netstat -ano | find /i "192.168.192.196:80" | find /i "ESTABLISHED" I get nothing. However, if I do the same thing, but change it to an HTTPSConnection: import httplib http_connection = httplib.HTTPSConnection("192.168.192.196") http_connection.request("GET", "/") http_connection.sock.settimeout(20) response = http_connection.getresponse() data = response.read() http_connection.close() Then do this: netstat -ano | find /i "192.168.192.196:443" | find /i "ESTABLISHED" I will actually see that the connection remains established until I actually ^Z out of the Python shell. This is happening in one of the applications I'm responsible for. Python isn't actually hanging there - it's simply leaving the connection open. Am I doing something wrong here? Do I need extra code to close the HTTPS connection? This is Python 2.6.4, btw.

  • C++ conversion operator between types in other libraries

    - by Dave
    For convenience, I'd like to be able to cast between two types defined in other libraries. (Specifically, QString from the Qt library and UnicodeString from the ICU library.) Right now, I have created utility functions in a project namespace: namespace MyProject { const icu_44::UnicodeString ToUnicodeString(const QString& value); const QString ToQString(const icu_44::UnicodeString& value); } That's all well and good, but I'm wondering if there's a more elegant way. Ideally, I'd like to be able to convert between them using a cast operator. I do, however, want to retain the explicit nature of the conversion. An implicit conversion should not be possible. Is there a more elegant way to achieve this without modifying the source code of the libraries? Some operator overload syntax, perhaps?

  • Put objects which are decorated with [DataContract] into a StateServer?

    - by Dave
    Is there anyway to stick objects which are decorated with DataContract attributes but not decorated with Serializable attributes in to a SqlServer StateServer? In other words, I would prefer not having to decorate these objects with the Serializable attribute as I will also have to implement IXmlSerizable on all of these objects because they do not have empty contstructors, and non-public setters for properties.
