• Graph API - Get events by owner/creator

  - by jwynveen

  Is there a way with the Facebook Graph API to get a list of all events created by a single profile? Our client creates a bunch of events and we want to pull a list of them all. I said that they would just have to make sure they set themselves to be attending the event, because then I can easily pull the list of events that profileId is attending, but I'm curious if there's another way. Maybe an FQL query? They look to require a query on the primary key though. And what would that FQL query look like if that's the way to do it??

• 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.

• Liquid templates - accessing members by name

  - by egarcia

  I'm using Jekyll to create a new blog. It uses Liquid underneath. Jekyll defines certain "variables": site, content, page, post and paginator. These "variables" have several "members". For instance, post.date will return the date of a post, while post.url will return its url. My question is: can I access a variable's member using another variable as the member name? See the following example: {% if my_condition %} {% assign name = 'date' %} {% else %} {% assign name = 'url' %} {% endif %} I have a variable called name which is either 'date' or 'url'. How can I make the liquid equivalent of post[name] in ruby? The only way I've found is using a for loop to iterate over all the pairs (key-value) of post. Beware! It is quite horrible: {% for property in post %} {% if property[0] == name %} {{ property[1] }} {% endif %} {% endfor %} Argh! I hope there is a better way. Thanks.

• What features are important in a programming language for young beginners?

  - by NoMoreZealots

  I was talking with some of the mentors in a local robotics competition for 7th and 8th level kids. The robot was using PBASIC and the parallax Basic Stamp. One of the major issues was this was short term project that required building the robot, teaching them to program in PBASIC and having them program the robot. All in only 2 hours or so a week over a couple months. PBASIC is kinda nice in that it has built in features to do everything, but information overload is possible to due this. My thought are simplicity is key. When you have kids struggling to grasp: if X>10 then <DOSOMETHING> There is not much point in throwing "proper" object oriented programming at them. What are the essentials needed to foster an interest in programming?

• OAuth iPhone client, problems with HTTP_AUTHORIZATION

  - by Rich

  Hi, I've been trying to implement OAuth in my iPhone app. However I have hit a problem. I have two servers, a local web server which is on my machine at home, I use this for testing. The machine is IIS 7 running PHP 5.08. Everything works fine on this server. However my live (web server) is running Apache and PHP 5.12. The problem is when I try to request a RequestToken the HTTP_AUTHORIZATION variable isn't posted to the web server, so I get an error returned from the server saying 'Invaild Consumer Key'. There is clearly a problem with the way the server is setup (as the code works on my local server). The code I am using is from this walkthrough http://code.google.com/p/oauthconsumer/wiki/UsingOAuthConsumer I have tried dumping the PHP headers and indeed HTTP_AUTHORIZATION is missing. Can anyone tell me how to fix this? (as it's driving me mad :)) Thanks Rich

• Running mongod as a windows service

  - by andreas

  Hello, i have installed mongodb on win32 and i am trying to run it as a service. I have followed the instructions posted here: http://www.deltasdevelopers.com/post/Running-MongoDB-as-a-Windows-Service.aspx but when when windows tries to 'load'/'run' the service there is a problem. I see the service under the services control banner constantly in the 'starting' state. The result: the service is not started and windows is constantly trying to start it without success. The instructions i have followed are: At the command line C:\mongodb\mongod -install then C:\mongodb\mongod -service Then i modified the Win Registry Entry for the MongoDB Service by setting the ImagePath key to the value of C:\mongodb\mongodb.exe -service Any advice? What am i doing wrong?

• Using Google AppEngine app as a OAuth provider

  - by Alistair

  Hi, I'm using the Google AppEngine 1.3.4 SDK which offers to allow your application to act as a OAuth service provider (http://code.google.com/appengine/docs/python/oauth/). Setting up a standard application on my localhost and using the following: Request URL /_ah/OAuthGetRequestToken Authorize URL /_ah/OAuthAuthorizeToken Access Token URL /_ah/OAuthGetAccessToken The client application just gets sent to a page requesting to grant OAuth access even though no user is logged in. Clicking 'Grant access' results in a message saying 'OAuth access granted' with no tokens or anything exchange. Can't see how this could work when it's not even prompting for a login. As this functionality is quite new I can't find much out there. I've created a OAuth provider before in Rails and know that you need a Consumer Key and Secret, something that seems to be lacking in GAE? Any ideas on how to get OAuth working in a sample GAE project are most welcome.

• Use VIM omnicomplete for javascript with ctags

  - by Gramic

  I am using vim/gvim for 4 months already and now I found a way to use it's strengths. My tags file is generated very well and here is a simple row in it. my.namespace.classname /path/to/file.js /^my.namespace.classname = function(first_arg,$/;" f Here is an example what i need to omnicomplete: my.namespace.cla <- omnicomplete list with all classnames in the my.namespace The above is the key to my problem, because it looks like omnicomplete searches only namespace without including "my." in front of it. So i see other element in the omnicomplete list and not my classname at all. However, if i type :tag my.namespace.classname for example gvim opens the correct file at the correct position. What is wrong and how can I make it work?

• PendingIntent from notification and application history conflicts

  - by synic

  I'm creating a notification with something similar to the following: Intent ni = new Intent(this, SomeActivity.class); ni.putExtra("somestring", "somedata"); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, ni, PendingIntent.FLAG_UPDATE_CURRENT|PendingIntent.FLAG_ONE_SHOT); Context context = getApplicationContext(); notification.setLatestEventInfo(context, res.getString(R.string.app_name), text, contentIntent); The key here is the extra data on the Intent for the notification. Once I click on the notification and it brings up SomeActivity, it brings up the activity and the extra data is available. However, if I exit the app, hold the home button until the recent activities list comes up, and choose to open the app again, the extra data is still passed. Is there a way I can make this data get passed only if the app is opened via the Notification, and not from the recent activities list?

• How can I hide a database column in the entity model?

  - by Nick Butler

  Hi. I'm using the Entity Framework 4 and have a question: I have a password column in my database that I want to manage using custom SQL. So I don't want the model to know anything about it. I've tried deleting the property in the Mapping Details window, but then I got a compilation error: Error 3023: Problem in mapping fragments starting at line 1660:Column User.Password in table User must be mapped: It has no default value and is not nullable. So, I made the column nullable in the database and updated the model. Now I get this error: Error 3004: Problem in mapping fragments starting at line 1660:No mapping specified for properties User.Password, User.Salt in Set Users. An Entity with Key (PK) will not round-trip when: Entity is type [UserDirectoryModel.User] Any ideas please? Thanks, Nick

• add ms ajax accordion pane at runtime loses previous pane issue

  - by Chris Conway

  I have an AjaxControlToolkit accordion control that i'm trying to load panes at runtime. When I click a button inside a listview, it should add a new pane to the accordion control. Here is the code that adds the pane in the onitemcommand event within the listview var pane = new AccordionPane { ID = key }; pane.HeaderContainer.Controls.Add(new LiteralControl(label.Text)); pane.ContentContainer.Controls.Add(LoadControl("~/UserControls/Covers/" + e.CommandArgument + ".ascx")); accordion.Panes.Add(pane); And this will successfully show a webcontrol inside the accordion control. But when I click on another button in the listview, the accordion is reset and it only shows the new pane instead of appending a new pane. Is there any way to keep the previous pane visible across postbacks like this? By the way, each of the webcontrols that are loaded in the accordion have input fields that will need to be persisted across postbacks as well. thanks!

• how to better use of eclipse code templates (PHP)?

  - by pocketfullofcheese

  One particular problem I was having was using ${word_selection} in an Eclipse PDT template. I was recently trying to use some code templates with Eclipse PDT 2.1 to speed up some common tasks. We use a lot of getters/setters, so I wrote the following template. function get${word_selection}() { return $$this->getData('${word_selection}'); } function set${word_selection}($$${word_selection}) { $$this->setData('${word_selection}', $$${word_selection}); } I named the template "getset" and the only way I know to use the Code Assist is to type: "getset" then hit my code assist keys (I have it set to Esc, but I think the default was Ctrl+Space). The problem is, this doesn't actually let me select a word to be used by the ${word_selection}. how do I type in my template name, hit the key combo, and have a word selected all at the same time? I also want to know what kinds of templates people have set up and any other tips for using templates to speed of programming.

• Calendar Table - Week number of month

  - by Saif Khan

  I have a calendar table with data from year 2000 to 2012 (2012 wasn't intentional!). I just realize that I don't have the week number of month (e.g In January 1,2,3,4 February 1,2,3,4) How do I go about calculating the week numbers in a month to fill this table?

• Scala: working around the "illegal cyclic reference"

  - by Paul Milovanov

  Hi all, I'm trying to implement a HashMap-based tree that'd support O(1) subtree lookup for a given root key. To that goal, I'm trying to do the following: scala> type Q = HashMap[Char, Q] <console>:6: error: illegal cyclic reference involving type Q type Q = HashMap[Char, Q] ^ So the question is, is there a way for me to do something of the sort without resorting to the ugly HashMap[Char, Any] with subsequent casting of values to HashMap[Char, Any]? Now, I also see that I can use something like the following to avoid the cyclic-reference error, and it might even be cleaner -- but it'd be nice to find out how to correctly do it the first way, just for the educational value. import collections.mutable.HashMap class LTree { val children = new HashMap[Char, LTree] } Thanks a bunch.

• Data validate tools (ETL tools) for SQL server

  I have some data in Excel and need to import into database. Is there any tool that can validate and maybe clean the data? Does Red Gate have such tool? The input will be Excel. Given table constraints, eg. CHECK, UNIQUE KEY, datetime format, NOT NULL. Desire output should be as least shows which lines are having problems, and then fix some trivial error automatically, like fill in default value for NULL columns, automatically correct datetime format. I know using Python can build such a script. But just wonder what's the popular way to do this. Thanks.

• QWidget keyPressEvent override

  - by eaigner

  Hi there, I'm trying for half an eternity now overriding QWidgets keyPressEvent function in QT but it just won't work. I've to say i am new to CPP, but I know ObjC and standard C. My problem looks like this: class QSGameBoard : public QWidget { Q_OBJECT public: QSGameBoard(QWidget *p, int w, int h, QGraphicsScene *s); signals: void keyCaught(QKeyEvent *e); protected: virtual void keyPressEvent(QKeyEvent *event); }; QSGameBoard is my QWidget subclass and i need to override the keyPressEvent and fire a SIGNAL on each event to notify some registered objects. My overridden keyPressEvent in QSGameBoard.cpp looks like this: void QSGameBoard::keyPressEvent(QKeyEvent *event) { printf("\nkey event in board: %i", event->key()); //emit keyCaught(event); } When i change QSGameBoard:: to QWidget:: it receives the events, but i cant emit the signal because the compiler complains about the scope. And if i write it like this the function doesn't get called at all. What's the problem here?
