• OCR for Devanagari (Hindi / Marathi / Sanskrit)

  - by Egon

  Does anybody have any idea about any recent work being done on optical character recognition for Indian scripts using modern Machine Learning techniques ? I know of some research being done at ISI, calcutta, but nothing new has come up in the last 3-4 years to the best of my knowledge, and OCR for Devanagari is sadly lacking!

• do I use document.activeElement to detect focus changes?

  - by jedierikb

  After looking at the answers here: http://stackoverflow.com/questions/497094/how-do-i-find-out-which-javascript-element-has-focus http://stackoverflow.com/questions/483741/how-to-determine-which-html-page-element-has-focus I can see that using document.activeElement is a great way to know which element has focus. But how do I use document.activeElement to detect changes to focus (or maybe I don't and I need to research a better way. Want to know if I am barking up the wrong tree).

I am wondering, is there any way to minify them? Thanks

• How to develop my own sms Gateway ?

  - by waheed

  I intend to develop an SMS gateway in c#, but i am doubtful about it's feasibility, because my initial research had shown that an SMS gateway had to cover for protocol differences. So what exactly a gateway had to do, further if i use SMPP, so is it possible to send/receive SMS to/from any number in the world by simply using SMPP ?

• Example of test plan

  - by alex

  I have done some research and found test plan over 40 pages. It includes so many elements that it is difficult to keep track. Additionally, it is not provided any examples, just a description of the different tests such as acceptance test, system test, etc. If anyone have made some good and simple test plan for the development of a product and could share, so that I can gain inspiration with example would be very helpful.

• What problems have you solved using genetic algorithms/genetic programming?

  - by knorv

  Genetic algorithms (GA) and genetic programming (GP) are interesting areas of research. I'd like to know about specific problems you - the SO reader - have solved using GA/GP and what libraries/frameworks you used if you didn't roll your own. Questions: What problems have you used GA/GP to solve? What libraries/frameworks did you use? I'm looking for first-hand experiences, so please do not answer unless you have that.

• how to visualise/debug an imagemap?

  - by fearofawhackplanet

  I'm dynamically generating an imagemap for a chart tool I have. I was hoping to be able to set a border or color on the area tags so I could check everything was being generated with the right coords, but a little research shows this is not possible. So whats the easiest way to check my image map is correct? Are there any browser tools which will "visualise" the areas?

• Run bat file in Java and wait 2

  - by Savvas Dalkitsis

  This is a followup question to my other question : http://stackoverflow.com/questions/2434125/run-bat-file-in-java-and-wait The reason i am posting this as a separate question is that the one i already asked was answered correctly. From some research i did my problem is unique to my case so i decided to create a new question. Please go read that question before continuing with this one as they are closely related. Running the proposed code blocks the program at the waitFor invocation. After some research i found that the waitFor method blocks if your process has output that needs to be proccessed so you should first empty the output stream and the error stream. I did those things but my method still blocks. I then found a suggestion to simply loop while waiting the exitValue method to return the exit value of the process and handle the exception thrown if it is not, pausing for a brief moment as well so as not to consume all the CPU. I did this: import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class Test { public static void main(String[] args) { try { Process p = Runtime.getRuntime().exec( "cmd /k start SQLScriptsToRun.bat" + " -UuserName -Ppassword" + " projectName"); final BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream())); final BufferedReader error = new BufferedReader(new InputStreamReader(p.getErrorStream())); new Thread(new Runnable() { @Override public void run() { try { while (input.readLine()!=null) {} } catch (IOException e) { e.printStackTrace(); } } }).start(); new Thread(new Runnable() { @Override public void run() { try { while (error.readLine()!=null) {} } catch (IOException e) { e.printStackTrace(); } } }).start(); int i = 0; boolean finished = false; while (!finished) { try { i = p.exitValue(); finished = true; } catch (IllegalThreadStateException e) { e.printStackTrace(); try { Thread.sleep(500); } catch (InterruptedException e1) { e1.printStackTrace(); } } } System.out.println(i); } catch (IOException e) { e.printStackTrace(); } } } but my process will not end! I keep getting this error: java.lang.IllegalThreadStateException: process has not exited Any ideas as to why my process will not exit? Or do you have any libraries to suggest that handle executing batch files properly and wait until the execution is finished?

• Silverlight P2P App (In Browser) - Will we get RTMFP?

  - by Paul

  Ok so from all my research I'm fairly positive P2P is not possible in Silverlight 4 (in browser). Flash can do P2P using Stratus/RTMFP which I believe uses UDP hole punching and a Stratus server to help initialize the connection. Is there any plans for Microsoft to add some kind of p2p rendezvous service in the future? Can we get a definitive yes/no on whether or not p2p is possible in SL4.

• STUN, TURN, ICE library for Java.

  - by Hemeroc

  I need to establish a P2P UDP and TCP Connection between two Users. Both of them are behind a NAT. A little research leads me to STUN, TURN and ICE. Is there any Java solution (library) except jSTUN which seems to work only on UDP. And TURN, ICE is much better for the symmetric NAT Problem.

• Detect when application is running in a VM environment

  - by Malcolm

  Looking for ideas on how to detect when our Windows application is running in one of the following VM environments. Some starter ideas for detection are in parentheses. There may be (much) better detection techniques - the starter ideas I've come up with are based on my Google research. VMWare (looking for the presence of optional VMware Tools is one way) Microsoft Virtual PC (have a device named "Virtual HD" for their IDE disks, "MS Virtual SCSI Disk Device" for their SCSI disks) Citrix Xen Sun Virtual Box Thank you, Malcolm

• Add querystring parameters to link_to

  - by Craig

  I'm having difficultly adding querystring parameters to link_to UrlHelper. I have an Index view, for example, that has UI elements for sorting, filtering, and pagination (via will_paginate). The will_paginate plugin manages the intra-page persistence of querystring parameters correctly. Is there an automatic mechanism to add the querystring parameters to a give named route, or do I need to do so manually? A great deal of research on this seemingly simple construct has left me clueless.

• Any Open Source Pregel like framework for distributed processing of large Graphs?

  - by Akshay Bhat

  Google has described a novel framework for distributed processing on Massive Graphs. http://portal.acm.org/citation.cfm?id=1582716.1582723 I wanted to know if similar to Hadoop (Map-Reduce) are there any open source implementations of this framework? I am actually in process of writing a Pseudo distributed one using python and multiprocessing module and thus wanted to know if someone else has also tried implementing it. Since public information about this framework is extremely scarce. (A link above and a blog post at Google Research)
