• How to get Wordpress MU / BuddyPress wp_signup meta data

  - by Ryan

  I am trying to get a value from the meta data that is stored in the wp_signups table for a Wordpress MU / BuddyPress installation. I see it's stored in the meta field as s:3:"age";s:2:"25"; ...which is age = 25 I put the information there using $usermeta['age'] = $_POST['signup_age']; in a plugin subscribing the the bp_signup_usermeta filter. I need to get it back during a function subscribing to bp_before_activate_content. How can I do this? Whats the function call? (searched documentation to no avail)

• Best practices on what data to collect in an in-app web analytics

  - by Anton Gogolev

  Hi! In our SaaSy webapp we need to collect Google Analytics-like data (like, what pages were visited, how many 404s where there, etc.). I wonder if there are any best practices on what pieces of information should be collected (like, IP, User Agent, etc.) and how should these logs be stored. Requirements on what statistics we're going to display are not yet fixed, but I want to have a starting point. Can you help me out with this? Thanks.

• Geodjango: importing data from OSGB_1936, displaying in WGS84?

  - by AP257

  I have some polygon data saved in a PostGIS database with projection SRID 27700. geom = models.MultiPolygonField(srid=27700) I want to display the shapes on OpenStreetMap, i.e. with SRID 900913 (I think?). So, two questions: How do I change the code below to output with the right SRID for OpenStreetMap? How can I change the Django code below to give me a nice json object, ready to display as a polygon? area = get_object_or_404(soa.objects, code=my_code) polygon = area.geom return render_to_response('area.html', { 'area': area }, context_instance = RequestContext(request)) Apologies if this question doesn't make sense - I'm pretty new to GeoDjango.

• How can I encode four unsigned bytes (0-255) to a float and back again using HLSL?

  - by Statement

  Hello! I am facing a task where one of my hlsl shaders require multiple texture lookups per pixel. My 2d textures are fixed to 256*256, so two bytes should be sufficient to address any given texel given this constraint. My idea is then to put two xy-coordinates in each float, giving me eight xy-coordinates in pixel space when packed in a Vector4 format image. These eight coordinates are then used to sample another texture(s). The reason for doing this is to save graphics memory and an attempt to optimize processing time, since then I don't require multiple texture lookups. By the way: Does anyone know if encoding/decoding 16 bytes from/to 4 floats using 1 sampling is slower than 4 samplings with unencoded data?

• CoreData many-to-many relationship NSPredicate Exceptions

  - by user307550

  I'm trying to model a Person/Team relationship. It's a many to many relationship since a person can belong to multiple teams and a team can have multiple people. As suggested by the doc I created an intermediate entity called TeamMember. I am now trying to run a query to see if I have a list of people, whether a pre-existing Team already exists for them so I'm not storing duplicate Teams in the database NSFetchRequest *request = [[[NSFetchRequest alloc] init] autorelease]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Team" inManagedObjectContext:[pm managedObjectContext]]; [request setEntity:entity]; NSPredicate *predicate = nil; predicate = [NSPredicate predicateWithFormat:@"ALL %K IN %@", @"teamMembers.person", players]; players is an NSSet of people that I'm trying to search I'm getting the following exception: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unsupported predicate ALL teamMembers.person IN { (entity: Person; id: 0x1334470 ; data: { Ideally I would like them to match exactly and not just do an IN as well.

• Asking facebook for data of multiple users in single request using FB.api

  - by gruszczy

  I need to get basic user data from Facebook using FB.api('/<some_id>/'). This works well, but is slow, since I need to ask for every id separately and make several calls to facebook. Is there any way to gather all ids and ask for them in single request and get an array? EDIT I am not asking for user friends. I am actually trying to gather friends' friends of a user and that's something Facebook doesn't provide, that's why I am using graph.facebook.com/<id>/ rather than graph.facebook.com/me/friends. I don't want friends, I'd like to do something like this: graph.facebook.com/<id1>,<id2>,<id3>,../

• How can I sort by a transformable attribute in an NSFetchedResultsController?

  - by Mike Laurence

  I'm using NSValueTransformers to encrypt attributes (strings, dates, etc.) in my Core Data model, but I'm pretty sure it's interfering with the sorting in my NSFetchedResultsController. Does anyone know if there's a way to get around this? I suppose it depends on how the sort is performed; if it's always only performed directly on the database, then I'm probably out of luck. If it sorts on the objects themselves, then perhaps there's a way to activate the transformation before the sort occurs. I'm guessing it's directly on the database, though, since the sort would be key in grabbing subsets of the collection, which is the main benefit of NSFetchedResultsController anyway.

• Can't create flex4 project in flexbuilder using remoting or LiveCycle Data Servcies ES

  - by anopres

  I'm trying out the FlasBuilder ide with ColdFusion 8 on OS X. When I try to create a new project, I get stuck at the server setup screen that forces you to validate your paths for your ColdFusion root folder and your webroot. Every combination I try says either "LiveCycle Data Services is not installed at the specified location" or "Invalid root. The WEB-INF/flex folder must contain either flex-config.xml or services-config.xml." The flex-config.xml file is sitting in that directory. Is there some trick to getting this to work?

• ExtJS Data Grid Column renderer to have multiple values

  - by Podlsk

  Hi, I am wondering if it is possible in ExtJS to have several values of the data source available to the renderer of the column. For example with the "Actions" column, the id is passed to the renderer. However I require both the user_id and id passed to the render. How may I do this? table_cols = [{ header: "User ID", width: 30, sortable: true, dataIndex: 'user_id' }, { header: "Actions", width: 60, sortable: false, dataIndex: 'id', renderer: function(val) { //IF USER ID MEETS A CONSTRAINT PRINT THE ID } }]; Thanks.

• C# .net -> SQLite error: Unable to open the database file

  - by CODe

  Hello all, I'm getting "System.Data.SQLite.SQLiteException: Unable to open the database file." when I attempt to access the database to save a record upon the "first" opening of my program. Here's the thing, it works fine when debugging locally in Visual Studio, but stops working when I package the program in an installer, and then install the program somewhere. I was guessing that it was the location of the database, which I just have set at database.s3db without a path, because it is stored next to the program's exe, but how could that cause problems? I'm at a loss, any further ideas or suggestions for solving this problem would be greatly appreciated.

• Best/Most Comprehensive API for Stocks/Financial Data

  - by Wilco

  What is the most recommended free/public API for accessing financial market stats and stock quotes (preferrably real-time quotes)? I'm not too picky about how it's exposed (SOAP, REST, some proprietary XML setup, etc.), as long as it's got some decent documentation. I'm planning to build a simple web dashboard in PHP with some basic data (basically a quick-n-dirty homepage), but may want to grow it into a full blown web app eventually. Any thoughts? As I find some, I'll post a list here (feel free to comment if you've used any of them before): Free opentick (soprano) Not Free XigniteRealTime

• How to get objects after CoreData Context merged

  - by Emmettoc

  Hi, I tried to save data and merge with CoreData and multi-thread for iPhone app. But I can't get managed objects in the main thread after merging. I wrote code just like this: [managedObjectContext performSelectorOnMainThread:@selector(mergeChangesFromContextDidSaveNotification:) withObject:notification waitUntilDone:YES]; [self performSelectorOnMainThread:@selector(didMerged:) withObject:objectIds waitUntilDone:YES]; So I tried to pass objectIds to get NSManagedObject instances in the main thread which were generated in another thread. At first I tried "objectWithId" method but it generated fault objects. Then I tried "existingObjectWithID" method but it generated objects partly and others were nil with following Error: [Error] Error Domain=NSCocoaErrorDomain Code=133000 "Operation could not be completed. (Cocoa error 133000.)" What is wrong? Is there any way how to retrieve all objects by objectIds after merging in another thread? Thank you.

• Install a file which should be removed only on real uninstall and never overwritten

  - by Viv Coco

  When I install my application, along with the binaries, a conf file is installed that the user can change as he needs (it's actually the user data file). I would like this file to not be overwritten or deleted when a repair, upgrade, modify happens and it should be deleted only when a real uninstall happens. In other words: this conf file is installed along with the binaries and should never be touched again (overwritten/deleted) until a real uninstall happens (not repairs, modifies, upgrades) in which case it should be deleted. So I was thinking of doing: <Component Id="aaa.cfg" Guid="GUID"> <File Id="aaa.cfg" Source="aaa.cfg" KeyPath="yes" /> </Component> But I don't know how could I condition the component so that: 1) the component to be removed only on a real uninstall - not upgrades, repairs, modifies? 2) the file should in no case be overwritten if already exists. Thx, Viv

• NSRangeException Issue

  Hi, I am writing a Core Data-based iPhone app and I am new to Objective-C. I have a bug that I am really struggling to nail. The iPhone simulator keeps crashing with the following error message: 2010-03-21 17:37:40.583 Patients[3689:207] * Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray insertObject:atIndex:]: index (1) beyond bounds (1)' 2010-03-21 17:37:40.585 Patients[3689:207] Stack: ( 31007835, 2516698377, 31091771, 31091610, 601273, 197333, 3194546, 3141378, 25020, 29768673, 214570, 30740485, 204512, 29114749, 29505379, 29001194, 29252410, 29190487, 30794322, 30791263, 30788680, 39097877, 39098074, 2883503, 9912, 9766 ) This error happens when I press return on a textField. What happens when the return key is pressed is that an attribute on an entity is updated. I don't know what array is out of bounds as I am not using any arrays in my code! Is there any way of getting more detail as to where in my code the error is?? Thanks,

• Reporting on data when data is missing (ie. how to report zero activities for a customer on a given

  I want to create a report which aggregates the number of activities per customer per week. If there has been no activites on that customer for a given week, 0 should be displayed (i.e week 3 and 4 in the sample below) CUSTOMER | #ACTIVITIES | WEEKNUMBER A | 4 | 1 A | 2 | 2 A | 0 | 3 A | 0 | 4 A | 1 | 5 B ... C ... The problem is that if there are no activities there is no data to report on and therefor week 3 and 4 in the sample below is not in the report. What is the "best" way to solve this?

• How to Obtain Data to Pre-Populate Forms.

  - by Stan

  The objective is to have a form reflect user's defined constraints on a search. At first, I relied entirely upon server-side scripting to achieve this; recently I tried to shift the functionality to JavaScript. On the server side, the search parameters are stored in a ColdFusion struct which makes it particularly convenient to have the data JSON'ed and sent to the client. Then it's just a matter of separately iterating over 'checkable' and text fields to reflect the user's search parameters; jQuery proved to be exceptionally effective in simplifying the workload. One observable difference lies in performance. The second method appeared to be somewhat slower and didn't work in IE8. Evidently, the returned JSON'ed struct was seen as an empty object. I'm sure it can be fixed, though before spending any more time with it, I'm curious to hear how others would approach the task. I'd gladly appreciate any suggestions. --Stan

• SQLServer Replication, dealing with updating data in a subscriber without merging with the publisher

  - by FlySwat

  To simplify my problem, picture two databases, one is a publisher, one is a replicated subscriber. Most of the time, changes are configured in the publisher, and pushed to the subscriber once per day using transactional replication. (The subscriber is the main production database). However, on a rare occasion, we need to make a change directly to the subscriber database. This does not break replication, however to ensure consistency, we also want to replicate this single change back to the publisher database. My first thought was to make both databases publishers to each other, but that does not work. Merge replication also does not work as that merges the data together, and we really only want to push that single change from the subscriber back to the publisher. Is there some other replication scheme I can use here, or do I need to invent my own thing?
