  • 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

  • Programmatically determine whether to describe an object with "a" or "an"?

    - by MarathonStudios
    I have a database of nouns (ex "house", "exclamation point", "apple") that I need to output and describe in my application. It's hard to put together a natural-sounding sentence to describe an item without using "a" or "an" - "a house is BIG", "an exclamation point is SMALL", etc. Is there any function, library, or hack i can use in PHP to determine whether it is more appropriate to describe any given noun with A or AN?

  • Yaml Emitter in C++

    - by redmoskito
    Is there a C++ library for emitting YAML? Wikipedia mentions a c++ wrapper for libyaml, but the link is broken. The official YAML site only offers yaml-cpp, which was also suggested in this SO question, but cpp-yaml is only a parser, not an emitter. Am I out of luck? Edit: I'm looking for an object oriented interface, hence the C++ requirement. I know I could use libyaml's C interface in C++ code, but that's less than ideal.

  • Accurate Sleep for Java on Windows

    - by HaBaLeS
    Does anyone know a Library which provides a Thread.sleep() for Java which has an error not higher than 1-2 Millisecond? I tried a mixture of Sleep, error measurement and BusyWait but I don't get this reliable on different windows machines. It can be a native implementation if the implementation is available for Linux and MacOS too. EDIT The link Nick provided ( http://blogs.sun.com/dholmes/entry/inside_the_hotspot_vm_clocks ) is a really good resource to understand the issues all kinds of timers/sleeps/clocks java has.

  • In gzip libary, what's the difference between 'uncompress' and 'gzopen' ?

    - by Sol
    There are some functions to decompress in zlib library(zlib version 1.2.3) I want to decompress my source zip(.gz) file using 'uncompress' function. It is now working(error code -3) but gzopen is. It is still not working when I input payload pointer(passing gzip header) to 'uncompress' . So the question is "What's the valid arguments for uncompress function?" and If it needs different format, how can I make it? Google doesn't helpful this time :(

  • Why not use GDI+ from ASP.NET

    - by roygbiv
    I've been told that using GDI+ from ASP.NET is dangerous and undefined. Is that because there is no guarantee of a Device Context? Can someone explain? What are some of the alternatives? Here is the source: http://msdn.microsoft.com/en-us/library/system.drawing.aspx

  • Is there a way to set a handler function for when a set of events has happened in JavaScript?

    - by allyourcode
    eg I have two concurrent AJAX requests, and I need the result from both to compute a third result. I'm using the Prototype library, so it might look something like this: var r1 = new Ajax.Request(url1, ...); var r2 = new Ajax.Request(url2, ...); function on_both_requests_complete(resp1, resp2) { ... } One way would be to use polling, but I'm thinking there must be a better way.

    I found this interesting tutorial that explains the concept of view bean with some code snippets http://www.ibm.com/developerworks/ibm/library/i-extreme5/, but I'd like to view a complete (simple) web application in a real world scenario using plain JSP and view beans (not using struts, spring or jsf framework).

  • How To Read C# API From Java Background

    - by ChloeRadshaw
    I come from a Java background and have been using C# for the last year - So far the API docs I use are at MSDN (http://msdn.microsoft.com/en-us/library/ms132397.aspx). I tend to use the lightweight C# docs. What annoys me about that is that I don't see one page with details of the class, a list of members, a list of methods and properties like I would with a Java API definition. Is this possible?

  • What speech libraries are available in Linux?

    - by George Edison
    When it comes to TTS (text-to-speech) libraries in Linux, what choices do developers have? What libraries ship with the majority of distros? Are there minimal libraries? What functionality does each library offer? I'm approaching this primarily from a C++ point of view, although Python would suit me too.

  • Cross platform /dev/null in Python

    - by Tristan
    I'm using the following code to hide stderr on Linux/OSX for a Python library I do not control that writes to stderr by default: f = open("/dev/null","w") zookeeper.set_log_stream(f) Is there an easy cross platform alternative to /dev/null? Ideally it would not consume memory since this is a long running process.
