• How to compute the probability of a multi-class prediction using libsvm?

  - by Cuga

  I'm using libsvm and the documentation leads me to believe that there's a way to output the believed probability of an output classification's accuracy. Is this so? And if so, can anyone provide a clear example of how to do it in code? Currently, I'm using the Java libraries in the following manner SvmModel model = Svm.svm_train(problem, parameters); SvmNode x[] = getAnArrayOfSvmNodesForProblem(); double predictedValue = Svm.svm_predict(model, x);

  Are there any C++ libraries similar to Ncurses, but for Windows? It seems there are no ports of Ncurses and I need a really good display system like it. Any suggestions? Cross-platform is a plus.

• Creating a protected link

  - by user303907

  Is there a way to create a protected download link which is random, expiry, requires a password and pointing to a specific file in C# that is associated with IIS 7.0? Several random links can link to the same file. Built-in codes or perhaps 3rd party libraries? For example, http://www.example.com/<some random gibberish>/<md5 of file>/file.jpg

• scons LIBPATH generates additional library paths

  - by Anonym

  I'm building a C project using scons, some internal static libraries are build and the exe files are linked to it. However, setting: env['LIBPATH'] = ['#build/libs'] generates a -Llibs and a -Lbuild/libs argument to gcc: gcc -o edecode main.o pack16.o pack16le.o pack32.o pack32le.o pack64.o -Lbuild/libs -Llibs -lutillib Why's that ? I only told it to look in build/libs

• How to auto-generate externs for the Google Closure Compiler

  - by ivo

  Suppose you are working in a javascript project with several external library dependencies, and want to compile your sources using the Google Closure Compiler in ADVANCED_OPTIMIZATIONS mode. Since in this mode the compiler will rename your code calls to the external libraries objects and functions, you must provide externs, to prevent this renaming from happening. But, it is a lot of work to produce the externs by hand, so, what is the best way to auto-generate the appropriate extern from a given javascript lib?

• Eclipse classpath does not update changes in Project Properties

  - by Nassign

  I am using Eclipse 3.4.1 Build M20080911-1700 I have tried to change the classpath directories for jar and the source directory using the Project Properties - Java Build Path - Libraries Tab or Source Tab. When I click OK button and then return to the properties page, my changes were not applied. I have to resort in the work around by manually changing the eclipse ".classpath" project settings file. Any ideas?

• Technologies and standards in a Kindle

  - by danke

  I'm using the Kindle as an example of an embedded system to illustrate some points I'm making in a paper. Since I'm not an expert in all the technologies used, can those aware of them point them out. For example: the GUI is programmed in embedded Java (which is probably a bad choice) Whispernet is used for the wireless platform What are the libraries or underlying technologies and standards that this device uses?

• Simple 3x3 matrix inverse code (C++)

  - by batty

  What's the easiest way to compute a 3x3 matrix inverse? I'm just looking for a short code snippet that'll do the trick for non-singular matrices, possibly using Cramer's rule. It doesn't need to be highly optimized. I'd prefer simplicity over speed. I'd rather not link in additional libraries. Primarily I was hoping to have this on Stack Overflow so that I wouldn't have to hunt around for it or rewrite from scratch again next time.

Has anyone tried the code and faced similar situation?? And also What are the better libraries for music programming in Ruby?

• Eclipse: export running configuration

  - by Jack

  Hello, I wrote a complex Java application with eclipse that uses many .jar libraries included into project folder. Is there a quick way to export a running configuration of the application that allows me to run it from shell (I don't actually need to move it around machines, so no jar export or similar things). I just need to detach the execution from Eclipse, but since project has many settings I would like to export a script (maybe .sh or just a plain long line) automatically.. Thanks!

• Use different Python version with virtualenv

  - by Ulf

  I have a Debian system currently running with python 2.5.4. I got virtualenv properly installed, everything is working fine. Is there a possibility that I can use a virtualenv with a different version of Python? I compiled Python 2.6.2 and would like to use it with some virtualenv. Is it enough to overwrite the binary file? Or do I have to change something in respect to the libraries?

• Docking *inside* an editor

  - by Andy Thomas-Cramer

  I have a document type which has multiple presentations. Say I want to display the document in an RCP editor with a customizable subset of those presentations, in a layout chosen by the user. One option that has come up is docking-like behavior for the panels inside an individual editor, with drag-and-drop, resizing, closing, maybe rollover and floating. Clearly this would need usability testing, but my question here is of feasibility. Are there any existing libraries or e4 plans to support behavior like this?

• C# - How to compare 2 files fast?

  Typical approaches recommend reading the binary via FileStream and comparing it byte-by-byte. Would a checksum comparison such as CRC be faster? Are there any .NET libraries that can generate a checksum for a file?

• Comet without AJAX

  - by Carl Whalley

  Suppose I only had the regular J2SE http libraries but wanted to write a client for comet, say in Android etc, but not limited to that, i.e. not using a WebView. Since there's no browser I'm assuming you'd have to open the long term connections yourself ... is this feasible?

• Useful Java Annotations

  - by Jon

  I'm interested in finding out exactly which Java annotations people think are most useful during development. This doesn't necessarily have to limited to the core Java API, you may include annotations you found in third party libraries or annotations you've developed yourself (make sure you include a link to the source). I'm really interested in common development tasks rather than knowing why the @ManyToOne(optional=false) in JPA is awesome... Include the annotation and a description of why it's useful for general development.
