• Cache Auth Tokens (or Caching HTTP headers in General) - Best Practices

  - by viatropos

  I'm using the Ruby GData Library to access Google Docs and I recently got the GData::Client::CaptchaError because I was re-logging in with every request. Reading this post, it recommends not logging in with every request, but caching the authentication token. How do I go about doing that correctly? Google says it expires every 24 hours, and it doesn't seem like I should store it in the session, so what should I do? I'm using Ruby on Rails with all this. Thanks so much

• Android - Question on postDelayed and Threads

  - by Chris

  I have a question about postDelayed. The android docs say that it adds the runnable to the queue and it runs in the UI thread. What does this mean? So, for example, the same thread I use to create my layout is used to run the Runnable? What if I want it as an independent thread that executes while I am creating my layout and defining my activity? Thanks Chris

• rails declarative authorization, permit all actions for controller?

  - by SooDesuNe

  using the delcarative_authorization gem for rails, is there a shortcut to allow a role access to all controller actions? privileges do # default privilege hierarchies to facilitate RESTful Rails apps privilege :manage, :includes => [:create, :read, :update, :delete] end isn't sufficient, because I have more controlling methods than just CRUD in my controllers. Something like: role :foo do has_permission_on :bar, :to =>[:all] end would be perfect, but I'm not finding it in the docs.

• python multithreading for dummies

  - by albruno

  trying to find a simple example that clearly shows a single task being divided for multi-threading. Quite frankly... many of the examples are overly sophisticated thus.... making the flow tougher to play with... anyone care to share their breakthrough sample or point to an example? As well, what is the best docs? many google lookups are too specific (for me at this stage) Thanks in advance.

• Updating Commit Message in Mercurial MQ extension

  - by Jerub

  After using hg qnew and hg qrefresh to create and update a patch that I want to apply to my repository, but the commit message that I wrote when I did hg qnew was not very good, it did not reference the ticket number from trac, and I would like to say something in it about some of the issues that my commit addresses. How do I do something like hg qrewritemycommitmessage. I have examined the docs on the website (starting here: http://mercurial.selenic.com/wiki/MqExtension ) and I have come up blank.

• Can I use google API to convert a PDF into PNGs?

  - by Ken

  I have noticed that when you view PDFs in google docs the PDF viewer renders the PDF file into PNG images. I was wondering if you could use Google Data API to upload a PDF and get the URLs of the rendered PNG files? I have never used the google API or really had the extra time to learn it, but if it help me do this it will be well worth the extra time.

• flex coverflow adding links to the images

  - by nivcaner

  Hi, I'm using sebastiaan holtrop's cover flow component in Flex. I would like to be able to add the sources to the images using xml. I would also like each image to have its own URL assosiated with it, so when I click it (if it's in the front of the coverflow), I go to that URL. I'm a bit clueless as to how to get that done (this is the first time I use Flex and the project docs think I'm a higher level Flex programmer...). Thanks, Niv

• Can I make an UITableView reorderable while still allowing deletion of rows?

  - by mystify

  from the docs: the reordering control temporarily replaces any accessory view. So when I do implement tableView:moveRowAtIndexPath:toIndexPath: in the data source, I would automatically get those reordering controls, right? But when they replace the accessory view (which may be the deletion control, right), then the user can only reorder. So ... can I do both?

• Do I need to override the writing methods of NSDocument in subclasses for an application that will o

  - by Abizern

  I think I may be missing the obvious but I'm not sure. The section on subclassing NSDocument in the docs states that subclasses of NSDocument must override one reading and one writing method. If I'm creating a viewer application that will not write anything back, do I still need to override a writing method (returning what, nil?) or can I ignore it and make sure that there are no saving methods that can get called?

• Channels in Socket.io

  - by mat3001

  Hi, I am trying to broadcast a message through the Node.js service socket.io (http://socket.io/) to certain subset of all subscribers. To be more exact, I would like to use channels that users can subscribe to, in order to efficiently push messages to a couple hundred people at the same time. I'm not really sure if addEvent('channel_name',x) is the way to go. I have not found anything in the docs. Any ideas? Thanks Mat

• Berkeley DB: btree prefix comparison for directory-like keys?

  - by Mark Harrison

  I'm going to index a BDB with keys that look a lot like directory paths ('/foo/bar', '/foo/baz', etc, with levels of slashes generally < 10). Does anybody have any experience with using a Btree prefix comparison routine[1] for this? Are the savings worthwhile? Any references to experience papers on this subject?

• Why no DatePicker.setDateChangedListener() method

  - by OceanBlue

  Since most widgets have a standard method of setting a listener, setOnXXXListener(), just wondering why there is no setDateChangedListener() method for DatePicker? I know init(int, int, int, OnDateChangedListener) can be used for the same purpose, but surely there must be some reason why Google decided not to use the standard method here. I went through the API docs and couldn't find the reason. Would one of the gurus here know the answer to this?
