• Ruby on Rails POST parameters on redirect_to

  - by Splashlin

  I have to make a call to a different url in one of my controllers on my site. The problem is that with all the parameters the other site requires I'm overflowing the url. Is there anyway to call another url from the controller and send all of the parameters using a POST? I'm not expecting a response from the other site. Also, I think there's a way to do this using the Net::HTTP library thought I'm not sure how. Thanks

• Does Microsoft make available the .obj files for its CRT versions to enable whole program optimizati

  - by Leeks and Leaks

  Given the potential performance improvements from LTCG (link time code generation, or whole program optimization), which requires the availability of .obj files, does Microsoft make available the .obj files for the various flavors of its MSVCRT releases? One would think this would be a good place for some potential gain. Not sure what they have to lose since the IL that is generated in the .obj files is not documented and processor specific.

• Push alerts to notification tray app in Java

  - by Rich Anderson

  Hi - how do I push server alerts to tray apps in java without using xmpp or other heavy protocols? Do you recommend a way to accomplish this? I was planning to write an app which uses URLConnection on a server equipped with Comet but I doubt if that would work as the client requires a JS to be invoked and URLConnection is not a browser.. What is the best way to push instead of using a proprietary client-server approach?

• Is there a true all-in-one solution for PHP Development?

  - by Alex R

  I'm looking for a "SINGLE INSTALLER" solution for PHP Development. Is there anything out there which will give me a nice IDE, Web Server, Debugger, Database, etc, on a single install image (*.msi or *.exe)? This of course would be completely opposite of Eclipse PDT, which requires you to search and locate a bunch of additional components which never quite work together.

• How do I convert a System::IO::Stream^ to an LPCSTR for PlaySound?

  - by Jon Cage

  I'm trying to embed and then play back a .wav file in a C++/CLI app but all the examples I've seen which use PlaySound are in VB. I can't see how to get froma Stream^ to the LPCSTR which PlaySound requires: System::IO::Stream^ s = Assembly::GetExecutingAssembly()->GetManifestResourceStream ("Ping.wav"); LPCSTR buf = s->????; PlaySound(buf, NULL, SND_ASYNC|SND_MEMORY|SND_NOWAIT); I guess I need some sort of horrible .net memory conversion magic.

• Free SVN repo server without requiring a project

  - by Nathan Campos

  I want to know if there are any free Subversion repository hosting servers where you don't need to have a 'project' to host your C++ files in. I don't have a actual project, but I want to store my C++ in an SVN repository. I am looking for something like OpenSVN where you can upload your C++ files, but it requires you to have a project. Can you recommend a Subversion hosting service where you can upload your files to an account, rather than a project. Something like: http://www.test-svn.com/~nathanpc/

• How to make OSX application that just runs opens some file type and runs arbitrary Ruby code?

  - by taw

  It's trivial to make a program executable from shell - just put #!/usr/bin/ruby on top, chmod +x it and done. Unfortunately OSX won't let me associate file type with such scripts - it requires its .apps instead. This sort of distinction doesn't seem to exist on other operating systems. What's the simplest way of making such .app, which would merely execute some arbitrary Ruby code?

  We are about to embark on a major project which requires an Occasionally Connected Application. The MS Sync Framework seems to offer a good solution with Sync Services for ADO.NET. Has anyone used this in a production app, ideally with tens of thousands of users, and can you comment on how well it scales? Any other pitfalls or gotcha's? Thanks!

• Similar Application to GemBox for word

  - by darrick

  Hi all, I'm using GemBox for my project now. Currently my module requires only excel which is why I've tried and really like using this application. Talk to my PM about the possibility of purchasing it but they wanted something similar that might work for word documents as well as just excel so that others might use it as it is more common for word documents to be generated.

• Amazon S3 permissions

  - by Joe

  Trying to understand S3...How do you limit access to a file you upload to S3? For example, from a web application, each user has files they can upload, but how do you limit access so only that user has access to that file? It seems like the query string authentication requires an expiration date and that won't work for me, is there another way to do this?

• Why use mysql_real_escape_string, doesn't addslashes prevent everything?

  - by Webnet

  I was looking through the docs and stumbled onto mysql_real_escape_string() and I'm not understanding why it's useful when you can just addslashes(). Can someone show me a scenario as to why it's useful? I'm also curious why it requires a database connection.... that seems like a lot of overhead.

• iPhone development on Windows

  - by AngryHacker

  Is there a way to develop iPhone applications on Windows? I really don't want to get yet another machine. There is a project on http://code.google.com/p/winchain/wiki/HowToUse that seemed to work with iPhone 1.0, but had limited success with iPhone 2.0, plus it requires all the cygwin insanity. Is there anything else, or do I have to buy a mac?

• 'Invalid conversion from some_type** to const some_type**'

  - by petersohn

  I've got a function that requires const some_type** as an argument (some_type is a struct, and the function needs a pointer to an array of this type). I declared a local variable of type some_type*, and initialized it. Then I call the function as f(&some_array), and the compiler (gcc) says: error: invalid conversion from ‘some_type**’ to ‘const some_type**’ What's the problem here? Why can't I convert a variable to const?

• NoSuchMethodErrors say the darndest things

  So, I'm working in eclipse were everything compiles and runs correctly. However, when compiling under ant for the build server, A large number of tests fail with a NoSuchMethodError saying: class A implements B interface B extends C C requires method getSyncID() // standard getter for an int field. A.java contains getSyncID() A.class contains getSyncID() and yet the Error is still thrown. Does anyone know how the hell this could happen? how to fix it.

• How to determine expected license serial number by viewing an EXE File?

  - by Steve

  I was attempting to install an exe that requires a serial number before the install, which the vendor has not provided to us yet. This got my wheels turning about whether there is any information that can be gained from viewing an exe using a hex editor/VI/etc? Using VI to view an exe, I can see some sections of plain text, but it is difficult to determine what it refers to without any context around it. Is it possible to determine any information by reading an exe? Thanks

• Obtaining memory available to JVM at runtime

  - by Bo Tian

  I'm trying to sort a bunch of data such that that the size of data input to the program can be larger than the memory available to the JVM, and handling that requires external sort which is much slower than Quicksort. Is there any way of obtaining memory available to the JVM at runtime such that I could use in place sorting as much as possible, and only switch to Mergesort when data input is too large?

• Instantiating and referencing models in MVC

  - by fig-gnuton

  In MVC, should each model be a globally accessible singleton accessible to any view/controller? Or should the models be singletons that are dependency injected into any component that requires them? Or should a new model instance be created for each component that needs one, in which case events would be used to propagate changes across model instances of the same class?
