  - by Seu

  How do you get the Android's primary e-mail address (or a list of e-mail addresses)? It's my understanding that on OS 2.0+ there's support for multiple e-mail addresses, but below 2.0 you can only have one e-mail address per device.

• Usecase for Workflow Engine

  - by Icarus

  Hi, We have an issue where a Database table has to be updated on the status for a particular entity. Presently, its all Java code with a lot of if conditions and an update to the status. I was thinking along lines of using a Workflow engine since there can be multiple flows in future. Is it an overkill to use a Workflow Engine here... where do you draw the line ?

• Django admin breaking with non-default primary_key for model with a m2m relationship ?

  - by Gj

  I have a simple Post model with a m2m field to a Tag model. The Tag had for some reason to use a non default primary key. Inside the admin page for a Post, the labels for the multiple selection field for Tags appear, but not the input field itself. I also tried using the filter_horizontal for the tags, but still only the labels appear without the actual field. Any ideas why it breaks and/or workarounds? Thanks!

• Concurrent threads adding to ArrayList at same time - what happens?

  - by Marcus

  We have multiple threads calling add(obj) on an ArrayList. My theory is that when add is called concurrently by two threads, that only one of the two objects being added is really added to the ArrayList. Is this plausable? If so, how do you get around this? Use a synchronized collection like Vector?

• Code Analysis In Python

  - by Jerub

  What tools are good to use for code analysis in python? I have a large source repository split across multiple projects, and I would like to be able to run tools across the directories to see details like Cyclomatic Complexity, and perhaps be able to spot errors using static analysis. Ideally, I would like to be able to produce a report about the health of the source code, so we can spot problem areas that need to be addressed.

• What's the difference between the ruby irb prompt modes?

  - by Steven

  I can change the irb prompt mode with irb --prompt prompt-mode I can see what null and simple does, but I can't tell the difference between null and xmp and the difference between default/classic/inf-ruby. Can someone explain to me what these other modes do? It seems pointless to have multiple modes doing the same thing.

• Did Java invent interfaces?

  - by Jordão

  I know about C++ pure virtual classes, but Java went one step further and created a first-class (no pun intended) concept for multiple-interface (not implementation) inheritance, the interface. It's now a staple of major statically-typed languages. Did Java invent the interface concept? Or did it appear in older languages also as a first-class concept?

• How can I alter anythingSlider so that it disables the next / previous buttons when only 1 <li> in t

  - by madphill

  I have a page with multiple instances of anythingSlider on it and I'm using PHP to dynamically load pages that swap out the content in them. Reference: http://ceedcreative.com/CEED_2.0/ I would like to edit the anythingSlider to disable the previous / next buttons if the UL it's displaying only has one LI within it. In other words, no buttons, just a clean div that's the same heigh and width (no scrolling) if there's only one image.

  I have multiple language packs in my NSIS installer, using the MUI2 interface. Now I try to select the language pack, which is installed by the "Typical" installation type according to the user's chosen setup language. My problem is, that I can't figure out, how to get the user's language selection.
