• Facebook JS API: Is it possible streamPublish to many targets at once?

  - by Prody

  I'm trying to make my app publish to all my friend's walls. From what I read in the API docs, the streamPublish method only allows you to publish to one person at a time. What I'm doing is fetching all the friends with FB.Facebook.apiClient.friends_get then a for on the reuslts, and a streamPublish for every one. This however seems hacky. Is it possible to streamPublish to many targets at once?

• iPhone UIWebView touch cause Toolbar to appear

  - by BahaiResearch.com

  I am trying to have a UI which is a full screen UIWebView. When the view is touched the tool bar appears. I can do everything but get the touchend event in the UIWebView. I have tried putting a UIColor.Clear'd UIView ontop and catching TouchEnd there and passing it on, but would like a better solution. I understand that we are not supposed to subclass the UIWebView from the docs. Ideas?

• postgresql drop table

  - by Russell

  I have two tables (tbl and tbl_new) that both use the same sequence (tbl_id_seq). I'd like to drop one of those tables. On tbl, I've removed the modifier "not null default nextval('tbl_id_seq'::regclass)" but that modifier remains on tbl_new. I'm getting the following error: ERROR: cannot drop table tbl because other objects depend on it DETAIL: default for table tbl_new column id depends on sequence tbl_id_seq After reviewing http://www.postgresql.org/docs/9.1/static/sql-droptable.html It looks like there is only CASCADE and RESTRICT as options.

• wsgi-served page does not refresh

  - by Steve

  I recently got my first app to work in uWSGI with Cherokee. I used the following code taken from the uWSGI docs: def application(environ, start_response): start_response('200 OK', [('Content-Type', 'text/plain')]) yield 'Hello World\n' The page correctly reads Hello World. When I change that text to New Thing and refresh, nothing changes. What am I forgetting? What I've tried: clearing browser history and cache stopping and starting Cherokee

• Facebook Like Button (<fb:like>) Height Always 80px

  - by David

  Why is the height of my Facebook Like button (technically the iframe that gets generated) always getting set to 80px? Example page is here: http://www.davidkasper.net/test.html I am using the javascript sdk and have had it work on other pages but for some reason the height will not change dynamically on this one! I can even do something like <fb:like style="height:40px"> and that will indeed set the visible height, but the iframe will still be 80px, whereas I can see it changing in the demo at http://developers.facebook.com/docs/reference/plugins/like

• How to cutomize a modelform widget in django 1.1?

  - by muudscope

  I'm trying to modify a django form to use a textarea instead of a normal input for the "address" field in my house form. The docs seem to imply this changed from django 1.1 (which I'm using) to 1.2. But neither approach is working for me. Here's what I've tried: class HouseForm(forms.ModelForm): address = forms.Textarea() # Should work with django 1.1, but doesn't class Meta: model = House #widgets = { 'address': forms.Textarea() } # 1.2 style - doesn't work either.

• Printing user specified column from JTable

  - by technomage

  I have an application, and I would like to print a JTable, but since it has many columns, I would like user to select/limit which columns to print so it can fit in regular printer paper. I'm using JTable.print() function to print. (http://java.sun.com/docs/books/tutorial/uiswing/misc/printtable.html) Right now, my solution, is to create another JTable with the columns that user selected, then repopulate the table with the data, then send it to printer. Is there a better way to do it?

• Abstract classes and Pod::Coverage

  - by Ken Williams

  I've recently started to try to use Dist::Zilla for maintaining Path::Class. I added the [PodCoverageTests] plugin, and it's reporting some failures in the Path::Class::Entity class, which is the abstract base class for Path::Class::File and Path::Class::Dir. What I'd like is some way to tell the testing code that Entity doesn't need docs, but its two derived classes do - even though the methods are only defined in the parent class. Anyone know some way to do that?

• Current tasks count at Appengine Task Queue

  - by splix

  Are there any ways to get count of current unfinished tasks at Google Appengine development server? I need it for making my integration test. I found a way to get this when running it local (just in mem), as described at appengine docs. But when i'm running it as a standalone server, from maven, this doesn't work. Just because library appengine-testing conflicts with Appengine SDK classes, and i can't use those classes together, when running sdk dev server.
