  • MongoDB initialization error in Rails

    - by rube_noob
    I have an initialization script to set up my MongoDB connection in the config/initialization directory. It is my understanding that these initializers run after all of the plugins are initialized. The problem I am having is that when a particular plugin I am using is initialized, it tries to access the mongodb before I have set it up. I get this error: uninitialized class variable @@database_name in MongoMapper My question is: Where can I initialize Mongodb that will run after the mongodb gem has been loaded and before any of the plugins are initialized?

  • Implementing dynamic scope when using CPS as intermediate language

    - by asandroq
    I am currently studying the implementation of programming languages and became interested in using Continuation-Passing Style as the intermediate language of the compiler. I also want to implement limited dynamic scope (for exception-handling or Scheme parameter objects) but I cannot find the relevant literature. I think it can be done with a separate environment passed as a variable to every closure, but this solution seems ugly to me. Could anyone point me to the relevant literature, or give me an idea of how this can be done?

  • Why does this JSON.parse code not work?

    - by SuZi
    I am trying to pass json encoded values from a php script to a, GnuBookTest.js, javascript file that initiates a Bookreader object and use the values i have passed in via the variable i named "result". The php script is sending the values like: <div id="bookreader"> <div id="BookReader" style="left:10px; right:10px; top:30px; bottom:30px;">x</div> <script type="text/javascript">var result = {"istack":"zi94sm65\/BUCY\/BUCY200707170530PM","leafCount":"14","wArr":"[893,893,893,893,893,893,893,893,893,893,893,893,893,893]","hArr":"[1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155,1155]","leafArr":"[0,1,2,3,4,5,6,7,8,9,10,11,12,13]","sd":"[\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\",\"RIGHT\",\"LEFT\"]"}</script> <script type="text/javascript" src="http://localhost:8080/application/js/GnuBookTest.js"></script> </div> </div> and in the GnuBookTest.js file i am trying to use the values like: br = new BookReader(); // Return the width of a given page. br.getPageWidth = function(index) { return this.pageW[index]; } // Return the height of a given page. br.getPageHeight = function(index) { return this.pageH[index]; } br.pageW = JSON.parse(result.wArr); br.pageH = JSON.parse(result.hArr); br.leafMap = JSON.parse(result.leafArr); //istack is an url fragment for location of image files var istack = result.istack; . . . Using JSON.parse as i have written it above loads the Bookreader and uses my values correctly in a few web-browsers: Firefox, IE8, and desktop-Safari; but does not work at all in mac-Chrome, mobile-Safari, plus older versions of IE. Mobile safari keeps giving me a reference error msg: can't find variable: JSON. The other browsers just do not load the Bookreader and show the "x" instead, like they did not get the values from the php script. Where is the problem?

  • Jquery Effect Onunload

    - by j3frea
    I would like to use the jquery slideUp effect when the user navigates away from the page just to make the page look cool as it closes. I assume that I should use the onunload event but how can I delay the page closing long enough for the effect to run to completion. One of the options that came to mind is effectively hijacking the page closing function, storing it in some variable and then executing it once I had run my effect but I have no idea how I would do that. Any suggestions or alternative ideas are more than welcome

  • Can I make ruby send network traffic over a specific iface?

    - by rjorgenson
    I am writing a script that grabs the external IP address along with some other information about each iface. I can't figure out how to make ruby send traffic over a specific iface(eth0 and wlan0 for example). I am currently using the open-uri library to open http://whatismyip.org and read it into a variable. def get_external_ip begin open("http://whatismyip.org") { |f| return f.read } rescue return "none" end end Is there any way to specify this at runtime of the script or from within the script itself(ideally)?

  • Error 'duplicate definition' when compiling 2 c files that reference 1 header file

    - by super newbie
    I have two C files and one header that are as follows: Header file header.h: char c = 0; file1.c: #include "header.h" file2.c: #include "header.h" I was warned about 'duplicate definition' when compiling. I understand the cause as the variable c is defined twice in both file1.c and file2.c; however, I do need to reference the header.h in both c files. How should I overcome this issue?

Any Ideas? Thanks!

  • Check if BigInteger is not a perfect square

    - by Ender
    I have a BigInteger value, let's say it is 282 and is inside the variable x. I now want to write a while loop that states: while b2 isn't a perfect square: a ? a + 1 b2 ? a*a - N endwhile How would I do such a thing using BigInteger? EDIT: The purpose for this is so I can write this method. As the article states one must check if b2 is not square.

  • Python and mod_wsgi path issue

    - by jasonh
    I have an AIX 6.1 system that I've compiled and installed: Apache 2.2.21 (into /usr/local/mercurial) Python 2.7.2 (into /usr/local/bin and /usr/local/lib) mod_wsgi 3.3 (with the AIX fix #1 described here) Mercurial 2.0 (system-wide) However, when Apache starts, I get the following message in error_log: IOError: invalid Python installation: unable to open /usr/local/bin/lib/python2.7/config/Makefile (No such file or directory) See the problem? bin/lib doesn't exist. /usr/local/lib/python2.7/config/Makefile does exist though. However, I can't figure out where it's getting that path from. Here's the environment variables I've got: PYTHONHOME=/usr/local/bin PYTHONPATH=/usr/local/lib/python2.7 LIBPATH="/usr/local/mercurial/lib:$LIBPATH" PATH=/usr/local/bin:/usr/local/lib:$PATH LDR_CNTRL="MAXDATA=0x80000000" AIXTHREAD_SCOPE=S AIXTHREAD_MUTEX_DEBUG=OFF AIXTHREAD_RWLOCK_DEBUG=OFF AIXTHREAD_COND_DEBUG=OFF SPINLOOPTIME=1000 YIELDLOOPTIME=8 MALLOCMULTIHEAP=considersize,heaps:8 I've tried all sorts of combinations with and without PYTHONHOME, PYTHONLIB and PATH in envvars. My PATH, in case it matters is: /usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:/usr/opt/ifor/bin:/usr/local/bin:.
