• Creating 3rd party library in Android. Need suggestions!!

  - by Lalith

  Hello all, I am planning to create a 3rd party library for android application developers. Also the main concern is I do not want the users to make many changes to their code base. The following are the main things I want to clarify before diving into the project. 1) I want to attach my own event handlers dynamically to the application. As per above limitations I mentioned, I cannot make users put the relevant code in their handlers as I need to support existing applications as well. I found out that we cannot attach more than one event handler per one listener. For example Button.setOnclickListener(somelistener) .. will set one listener. In traditional desktop applications we can add more than one handlers but here if I do one more Button.setOnclickListener(someOtherListener) this one overwrites the previous listener. Is there any way I can attach my own listener along with application's existing listeners dynamically? Also is it really not supported on android yet? 2) Is there any 3rd party alternative that exists already that monitors user's interactions in androidi? 3) If this is not supported now are there any future plans to support this feature? Please let me know about this as I did not get much feedback on Stackoverflow. Any suggestions and workarounds would really help me continue with this project. Regards, Lalith

• Embedded Development Board

  - by ALF3130

  I'm new to the embedded development world and am looking to get my very first board. After some research, I realize that there aren't many choices with FPUs. This is important in my project as I'm going to be doing quite a bit of floating point computations. I found the Mini2440 which seems to run on the ARM920T core. This particular unit is perfect for my needs (decent price, all the right I/O ports, and a touch screen to boot) but it seems that it doesn't have an FPU. I don't know how big of a penalty I'd be paying for FP emulation, so I'm unsure of whether to pull the trigger on this one. That said: Can someone please confirm whether this product (Mini2440) has an FPU or not? My project will do image capture and analysis. Does anyone have any experience with running things like OpenMP on such platforms? Please suggest any other similar boards in the = $200 price range that have an FPU. This world is new to me. Any other advice or things I should be aware of is much appreciated.

• What Are Collections Implemented As In VB6?

  - by Tom Tresansky

  So a collection in VB6 keeps track of a key for each object, and you can look up the object by its key. Does that mean collections are implemented as some sort of hashtable under the hood? I realize you can have multiple items with the same key in a collection, hence the SOME SORT. Anybody know what type data structure a VB6 collection is supposed to represent?

• How to determine whether a database has been changed or not ?

  - by Locksfree

  I have a need to determine if a database on a MS SQL Server has changed between two distinct moments. The change can be structural or data-related and the check should be generic (i.e. independant of the structure of the database). Preferably, I'd like the check to be T-SQL based or with SMOs, not file based. I checked on MSDN but I haven't found anything relevant so far.

• writing 'bits' to c++ file streams

  - by Sorush Rabiee

  How can i write 'one bit' into a file stream or file structure each time? is it possible to write to a queue and then flush it ? is it possible with c# or java? this was needed when i try to implement an instance of Huffman codding. i can't write bits into files. so write them to a bitset and then (when compression was completed) write 8-bit piece of it each time (exclude last one).

• At which n does binary search become faster than linear search on a modern CPU?

  - by joeforker

  Due to the wonders of branch prediction, a binary search can be slower than a linear search through an array of integers. On a typical desktop processor, how big does that array have to get before it would be better to use a binary search? Assume the structure will be used for many lookups.

• Get coordinates of beads covering the surface of a protein

  - by Hefeweizen

  Given a protein structure from the PDB, I would like to generate NS spheres of radius Rs which cover totally the protein surface. Given RS there, NS is the maximum number of spheres so they do not overlap. I would need the coordinates of the center of each sphere. Does anybody know if this has been implemented in some method / program? Or how to do it with scripting. Thanks
