  • Problem creating PostGIS template database

    - by omat
    I am trying to build a template geographic database for PostGIS (1.5) on Mac OS X Snow Leopard (10.6) for my GeoDjango application. I am following: http://docs.djangoproject.com/en/dev/ref/contrib/gis/install/#creating-a-spatial-database-template-for-postgis I've managed to come up to the point where the provided postgis.sql should be run (i.e. psql -d template_postgis -f $POSTGIS_SQL_PATH/postgis.sql) At that point I am getting an error at the first SQL statement that is tried to be run. When I try that on the psql prompt the result is as follows: template_postgis=# CREATE OR REPLACE FUNCTION st_spheroid_in(cstring) RETURNS spheroid AS '/usr/local/pgsql/lib/postgis-1.5','ellipsoid_in' LANGUAGE 'C' IMMUTABLE STRICT; NOTICE: type "spheroid" is not yet defined DETAIL: Creating a shell type definition. ERROR: could not load library "/usr/local/pgsql/lib/postgis-1.5.so": dlopen(/usr/local/pgsql/lib/postgis-1.5.so, 10): Symbol not found: _DatumGetFloat4 Referenced from: /usr/local/pgsql/lib/postgis-1.5.so Expected in: /opt/local/lib/postgresql83/bin/postgres in /usr/local/pgsql/lib/postgis1.5.so Any ideas what might have been messed up?

  • Creating a custom Publishing Portal Web site in SharePoint 2010

    - by Jourdan
    Custom Web sites built on SharePoint are cropping up everywhere (just visit topsharepoint.com to see). With that said, my question pertains to creating a fully customized, branded site using SharePoint as the CMS as depicted by many of the topsharepoint.com sites. I understand the concept of creating the custom master master page(s) (SharePoint 2010 even includes a minimal.master to start). The problems I have are: What site template does one use? In 2007 the recommended front-facing Web site site collection template was the Publishing Portal. Is this still the case? What navigation do you use? Do you leverage the OOB navigation? If so, how do you style it extensively? How do you keep the on-page editing capabilities within the new site template? Are there any online tutorials are walk-throughs that address all of these issues? I have been searching, but it's really sparse out there.

  • Creating/populating Javascript custom object

    - by Ek0nomik
    I've created an ashx page which is going to serve me an XML document full of basic user information. I'm not sure which is the best way to go about creating and populating my custom javascript object. I've seen them created in two ways: function User() { this.Id; this.FirstName; this.LastName; this.Title; } and var User2 = { Id: null, FirstName: null, LastName: null, Title: null } I could populate each of these by doing something like: //first object User.Id = 1 //second object User2.FirstName = 'John' Is one method of creating the object better than the other?

  • Creating a "mountable" File System, where to start?

    - by Mike Curry
    A friend and I are thinking about creating a simple file system for learning purposes. We're going to write it in C/C++, and try to get it to a mountable state from within linux. We've both been coding or over 16 years (32 combined), so I suppose its just a matter of finding some documentation, and a ton of learning. My question is, where could I find out more information? (Documentation for creating a file system, requirements of mounting a file system in linux, etc) Where do we start? Edit: I should also mention, this would not be a boot-able file system, just a file system used for storage, though I am not too sure if that matters or not.

  • What is the best way to do server-side output caching in PHP?

    - by Paul Tarjan
    I have a pretty complicated index.php now, and I would like to only run it once every hour. What is the best way to achieve this? Some ideas I've had Put it in APC with apc_store($page, 60*60*) - I feel this isn't what APC is for and will probably be doing something bad to the other parts of my site Save the output to a filesystem somewhere - Then apache needs write access somewhere which might be a pain Somehow setup apache to do the caching for me - Is this possible?

  • Creating an Attribute to check for Exceptions

    - by BiffBaffBoff
    I'm creating an attribute so that whenever an exception occurs on my site, I'll receive an email detailing the exception. I've got so far but my Attribute code doesn't seem to fire if an exception occurs: public class ReportingAttribute : FilterAttribute, IExceptionFilter { public void OnException(ExceptionContext filterContext) { // This will generate an email to me ErrorReporting.GenerateEmail(filterContext.Exception); } } Then above my Controller I'm doing: [ReportingAttribute] public class AccountController : Controller The other way to do it is ofcourse putting ErrorReporting.GenerateEmail(ex) inside my catch blocks? There must be a simpler way? Thats why I thought of creating the Attribute to handle this

  • Creating objects makes the VM faster?

    - by Sudhir Jonathan
    Look at this piece of code: MessageParser parser = new MessageParser(); for (int i = 0; i < 10000; i++) { parser.parse(plainMessage, user); } For some reason, it runs SLOWER (by about 100ms) than for (int i = 0; i < 10000; i++) { MessageParser parser = new MessageParser(); parser.parse(plainMessage, user); } Any ideas why? The tests were repeated a lot of times, so it wasn't just random. How could creating an object 10000 times be faster than creating it once?

  • Monotouch creating UIViews with using() blocks

    - by Socram
    When i first started using monotouch i found a page with some code samples for simple and frequent tasks... but on some of those code samples i found some things like this one: var imageRect = new RectangleF(0f, 0f, 320f, 109f); using (var myImage = new UIImageView(imageRect)) { myImage.Image = UIImage.FromFile("myImage.png"); myImage.Opaque = true; view.AddSubview(myImage); } The UIImageView is created inside a using() block. I'm a .Net developer and i know what a using() does, but i dont understand why is it used on this example. So my question is if this is the best way of creating views, and what are the differences (if any) of this aproach and creating views without the using() block.

  • Python 2.7 creating a multidimensional list

    - by poop
    I don't know why I am having so much trouble creating a 3 dimensional list. I need the program to create an empty n by n list. So for n = 4: x = [[[],[],[],[]],[[],[],[],[]],[[],[],[],[]],[[],[],[],[]]] I've tried using: y = [n*[n*[]]] y = [[[]]* n for i in range(n)] Which both appear to be creating copies of a reference. I've also tried naieve application of the list builder with little success: y = [[[]* n for i in range(n)]* n for i in range(n)] y = [[[]* n for i in range(1)]* n for i in range(n)] I've also tried building up the array iteratively using loops, with no success. In my rapid flurry of attempts to not post something stupidly easy to SO, I came upon a solution: y = [] for i in range(0,n): y.append([[]*n for i in range(n)]) Is there an easier/ more intuitive way of doing this?

  • Creating Array of settings names and values using ADO.NET Entities

    - by jordan.baucke
    I'm using an ADO.NET Entities (.edmx) data-model along with MVC2 to build an application. I have a DB table where I want to store settings for method that run elsewhere. MVC2 allows me to create a view, editor, etc. to update this table which is great, but now when I want to do simple assignments based on column titles I'm a bit confused. For example, I would like to easily build an array that I could offset into the record's value based on it's "Title" Column: var entities = new ManagerEntities(); Setting[] settings = entities.settings.ToArray(); This returns something like: Settings[0].[SettingTitle][SettingValue] However, I would like to more easily index into the value than having to loop through all the returned settings, when they're already index. string URL_ID_NEED = [NeededUrl][http://www.url.com] Am I missing something relatively simple? Thanks! ========================= *Update* ========================= Ok, I think I've got a solution, but I'm wondering why this would be so complicated, and if I'm just not thinking of the right context for ADO.NET objects, here's what I did: public string GetSetting(string SettingName) { var entities = new LabelManagerEntities(); IEnumerable<KeyValuePair<string, object>> entityKeyValues = new KeyValuePair<string, object>[] { new KeyValuePair<string, object>("SettingTitle", SettingName) }; EntityKey key = new EntityKey("LabelManagerEntities.Settings", entityKeyValues); // Get the object from the context or the persisted store by its key. Setting settingvalue = (Setting)entities.GetObjectByKey(key); return settingvalue.SettingValue.ToString(); } This method handles the job of querying the Entities by "Key" to get back the correct value as a returned string (which I can than strip out the " ", or or cast to an integer, etc. etc.,) Am I just duplicating functionality that already exists in ADO.NET's design patterns (I'm pretty new to it) -- or is this a reasonable solution?

  • Django | Python creating a JSON response

    - by MMRUser
    Hi, I'm trying to convert a server side AJAX response script in to an Django HttpResponse, but apparently it's not working. This is the server-side script /* RECEIVE VALUE */ $validateValue=$_POST['validateValue']; $validateId=$_POST['validateId']; $validateError=$_POST['validateError']; /* RETURN VALUE */ $arrayToJs = array(); $arrayToJs[0] = $validateId; $arrayToJs[1] = $validateError; if($validateValue =="Testuser"){ // validate?? $arrayToJs[2] = "true"; // RETURN TRUE echo '{"jsonValidateReturn":'.json_encode($arrayToJs).'}'; // RETURN ARRAY WITH success }else{ for($x=0;$x<1000000;$x++){ if($x == 990000){ $arrayToJs[2] = "false"; echo '{"jsonValidateReturn":'.json_encode($arrayToJs).'}'; // RETURN ARRAY WITH ERROR } } } And this is the converted code def validate_user(request): if request.method == 'POST': vld_value = request.POST.get('validateValue') vld_id = request.POST.get('validateId') vld_error = request.POST.get('validateError') array_to_js = [vld_id, vld_error, False] if vld_value == "TestUser": array_to_js[2] = True x = simplejson.dumps(array_to_js) return HttpResponse(x) else: array_to_js[2] = False x = simplejson.dumps(array_to_js) test = 'Error' return render_to_response('index.html',{'error':error},context_instance=RequestContext(request)) return render_to_response('index.html',context_instance=RequestContext(request)) I'm using simplejson to encode the Python list (so it will return a json array).Coudn't figure out the problem yet.But I think that I did something wrong about the 'echo'. Anyway I'm expecting an good answer it will help me a lot. Thanks.

  • Creating a blocking Queue<T> in .NET?

    - by spoon16
    I have a scenario where I have multiple threads adding to a queue and multiple threads reading from the same queue. If the queue reaches a specific size all threads that are filling the queue will be blocked on add until an item is removed from the queue. The solution below is what I am using right now and my question is: How can this be improved? Is there an object that already enables this behavior in the BCL that I should be using? internal class BlockingCollection<T> : CollectionBase, IEnumerable { //todo: might be worth changing this into a proper QUEUE private AutoResetEvent _FullEvent = new AutoResetEvent(false); internal T this[int i] { get { return (T) List[i]; } } private int _MaxSize; internal int MaxSize { get { return _MaxSize; } set { _MaxSize = value; checkSize(); } } internal BlockingCollection(int maxSize) { MaxSize = maxSize; } internal void Add(T item) { Trace.WriteLine(string.Format("BlockingCollection add waiting: {0}", Thread.CurrentThread.ManagedThreadId)); _FullEvent.WaitOne(); List.Add(item); Trace.WriteLine(string.Format("BlockingCollection item added: {0}", Thread.CurrentThread.ManagedThreadId)); checkSize(); } internal void Remove(T item) { lock (List) { List.Remove(item); } Trace.WriteLine(string.Format("BlockingCollection item removed: {0}", Thread.CurrentThread.ManagedThreadId)); } protected override void OnRemoveComplete(int index, object value) { checkSize(); base.OnRemoveComplete(index, value); } internal new IEnumerator GetEnumerator() { return List.GetEnumerator(); } private void checkSize() { if (Count < MaxSize) { Trace.WriteLine(string.Format("BlockingCollection FullEvent set: {0}", Thread.CurrentThread.ManagedThreadId)); _FullEvent.Set(); } else { Trace.WriteLine(string.Format("BlockingCollection FullEvent reset: {0}", Thread.CurrentThread.ManagedThreadId)); _FullEvent.Reset(); } } }
