• What can I do to avoid losing original resolution when uploading or exporting photos from Picasa?

  - by Janet Levin

  I'm not a programmer, and/but after multiple email discussions and google searches confirmed the problem I'm describing, and after making changes in picasa preferences with no change in resolution loss (from say, 800kb original image to 235kb after export or upload), I'm at a dead end and thinking the answer may lie among you folks, even though I barely understand the language here.

• Does it make sense to fragment cache static partials

  - by ash34

  Hi, I have my views and layouts split into multiple partials, some of them are static partials i.e, no data from the database being displayed here. Does it make sense to cache these to prevent the erb templating system from generating the html each time or it only makes sense to cache in situations where something needs to be retrieved from the db each time. thanks, ash

• Is there an open source UITabbedView component available for the iPhone (iPad) SDK?

  - by smountcastle

  Is there an open source UIView component that supports multiple, dynamic tabbed views for the iPhone (iPad) SDK? I see several apps in the iPad App Store which utilize tabs, one such example is the Atomic Web Browser which provides a tabbed browsing experience (like Safari on the Mac or Firefox). Instead of reinventing this functionality, I'd like to reuse an existing component.

• Java: thread-safe RandomAccessFile

  - by Folkert van Heusden

  Hi, After some serious googleing I found out that the RandomAccessFile-class is not thread-safe. Now I could use one semaphore to lock all reads and writes but I don't think that performs very well. In theory it should be possible to do multiple reads and one write at a time. How can I do this in Java? Is it possible at all? Thanks!

• Efficient way to store tuples in the datastore

  - by Drew Sears

  If I have a pair of floats, is it any more efficient (computationally or storage-wise) to store them as a GeoPtProperty than it would be pickle the tuple and store it as a BlobProperty? If GeoPt is doing something more clever to keep multiple values in a single property, can it be leveraged for arbitrary data? Can I store the tuple ("Johnny", 5) in a single entity property in a similarly efficient manner?

  - by Jeesmon

  We are looking for open source tool for hosting our internal projects like "Google Project Hosting".

  - by Delan Azabani

  I've noticed the basic 'style' of most GNU core applications whereby arguments are: --longoption --longoption=value or --longoption value -abcdefg (multiple options) -iuwww-data (option i, u = www-data) They follow the above style. I want to avoid writing an argument parser if there's a library that does this using the above style. Is there one you know of?

  I know this is a simple question, but I haven't had the chance to test it in any browser other than Firefox. If I attach multiple event handlers to a single event on a single DOM element, are the event handlers guaranteed to be called in the order they were added? Or should I not rely on this behavior?
