  • Simulink: type consistency errors

    - by stanigator
    Using this Simulink model file as a reference, I'm trying to figure out the two following errors: I have no idea what has gone wrong with the data type consistency/conversion problems. Do you know what the error messages mean exactly in the context of a model? It would be great to get an interpretation of the problem to solve it. Thanks in advance.

  • Cucumber response object -- PHP environment

    - by trisignia
    Hi, I'm using Cucumber to test a PHP application, and while most everything works without issue, I haven't yet figured out how to retrieve a response object for a request -- I'm looking to test whether a response is successful (code 200) and also to perform some Hpricot parsings of the response body. Right now my env.rb file is pretty simple: require 'webrat' include Webrat::Methods include Webrat::Matchers Webrat.configure do |config| config.mode = :mechanize end And if I put something like this in my step definitions: Given /Debug/ do puts response.to_yaml end I get this error: undefined method `response' for nil:NilClass (NoMethodError) ./features/step_definitions/webrat_steps.rb:11:in `/Debug/' features/versions.feature:4:in `Given Debug' Is anyone familiar with this type of situation? best, Jacob

  • hibernate or eclipselink?

    - by opensas
    It seems like EclipseLink has been chosen by sun as the reference implementation of JPA 2.0, nevertheless I see lots of people continue to use hibernate... I have no experience with none of them, so I wonder which one should I choose for a new project... I'd like to know the pros / cons of each one... thanks a lot ps: btw, and this is part of the answer, there are 3636 questions on stackoverflow about hibernate, and only 68 about eclipselink...

    - by Luc M
    We are several persons using the same login id on Linux Box. I want to define my own aliases without interfering with anyone. In the .bashrc, I define a alias to my bash file defining my own aliases. alias luc=/full/path/to/my/def_alias_luc.sh The file /full/path/to/my/def_alias_luc.sh contains #!/bin/bash echo "" echo "Defining Luc's aliases" echo "" echo "" echo "aliases before..." echo "" alias alias vimluc="vim -u /full/path/to/my/.vimrc " echo "" echo "aliases after" echo "" alias After executing /full/path/to/my/def_alias_luc.sh, the alias is still undefined.

  • UIGraphicsGetCurrentContext threading problem

    - by Infinity
    Hello guys! The reference says this: "You should call this function from the main thread of your application only." But I would like to get the current graphics context from separate threads. What do you think? What can I do to reach this? Edit: Thanks guys for the answers. I don't know which is good for me at the moment, but thank you very much.

  • GhostScript font issues

    - by Robert
    I'm running GPL Ghostscript 8.70 (2009-07-31) on Windows XP. I have about 100 PDF files I've attempted to run through GS, but I'm having font-related issues on two separate groups of files from two different customers. I'm not sure if the issues could be related. Here are the two errors I receive: Loading Courier font from C:\Program Files\gs\fonts/cour.ttf... 2343384 986555 13583240 12261829 3 done. Using CourierNewPSMT font for Courier. Error: /rangecheck in --get-- Can't find CID font "Arial". Substituting CID font /Adobe-Identity for /Arial, see doc/Use.htm#CIDFontSubstitution. The substitute CID font "Adobe-Identity" is not provided either. Will exit with error. Error: /undefined in findresource I've tried just about everything I can think of with fontmap and cidfmap. Does anyone out there have a solution?

  • jquery boxy plugin: prevent multiple instances of the same dialog when clicking the link multiple ti

    - by Lyon
    Hi, I'm using the Boxy jQuery plugin to open dialog windows and populating it through ajax. http://onehackoranother.com/projects/jquery/boxy/ Here's my code so far: $("a.create").click(function (e) { url = $(e.target).attr('href'); Boxy.load(url, {title:'Test'}); }); This opens up a dialog alright. However, if I click the link again, another dialog will open. How can I make it such that the previously opened Boxy dialog will come into focus? I only want one instance of this dialog. I tried assigning a variable to var ele = Boxy.load(); but the variable ele returns undefined... Alas, I can't make out much from the limited Boxy documentation available. Enabling the option modal: true would prevent the user from clicking on the link multiple times, but I don't want the overlay to show. Thanks for any light you can shed on this. -Lyon

  • boost's regex won't compile

    - by myeviltacos
    Hi everyone. I am using boost 1.45.0 on Ubuntu with Code::Blocks as my IDE, and I can't get basic_regex.hpp to compile. I'm pretty sure I set up boost correctly, because I can compile programs using boost::format without any errors. But I'm getting this annoying error, and I don't know how to get rid of it. The code that is provoking the error: boost::regex e("\"http:\\\\/\\\\/localhostr.com\\\\/files\\\\/.+?\""); Compiler output (GCC): obj/Debug/main.o In function `boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::assign(char const*, char const*, unsigned int)' /home/neal/Documents/boost_1_45_0/boost/regex/v4/basic_regex.hpp|379| undefined reference to `boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::do_assign(char const*, char const*, unsigned int)'| ||=== Build finished: 1 errors, 0 warnings ===| Did I miss a step when setting up boost, or should I downgrade to another version of boost?

  • Seeking for faster $.(':data(key)')

    - by PoltoS
    I'm writing an extension to jQuery that adds data to DOM elements using el.data('lalala', my_data); and then uses that data to upload elements dynamically. Each time I get new data from the server I need to update all elements having el.data('lalala') != null; To get all needed elements I use an extension by James Padolsey: $(':data(lalala)').each(...); Everything was great until I came to the situation where I need to run that code 50 times - it is very slow! It takes about 8 seconds to execute on my page with 3640 DOM elements var x, t = (new Date).getTime(); for (n=0; n < 50; n++) { jQuery(':data(lalala)').each(function() { x++; }); }; console.log(((new Date).getTime()-t)/1000); Since I don't need RegExp as parameter of :data selector I've tried to replace this by var x, t = (new Date).getTime(); for (n=0; n < 50; n++) { jQuery('*').each(function() { if ($(this).data('lalala')) x++; }); }; console.log(((new Date).getTime()-t)/1000); This code is faster (5 sec), but I want get more. Q Are there any faster way to get all elements with this data key? In fact, I can keep an array with all elements I need, since I execute .data('key') in my module. Checking 100 elements having the desired .data('lalala') is better then checking 3640 :) So the solution would be like for (i in elements) { el = elements[i]; .... But sometimes elements are removed from the page (using jQuery .remove()). Both solutions described above [$(':data(lalala)') solution and if ($(this).data('lalala'))] will skip removed items (as I need), while the solution with array will still point to removed element (in fact, the element would not be really deleted - it will only be deleted from the DOM tree - because my array will still have a reference). I found that .remove() also removes data from the node, so my solution will change into var toRemove = []; for (vari in elements) { var el = elements[i]; if ($(el).data('lalala')) .... else toRemove.push(i); }; for (var ii in toRemove) elements.splice(toRemove[ii], 1); // remove element from array This solution is 100 times faster! Q Will the garbage collector release memory taken by DOM elements when deleted from that array? Remember, elements have been referenced by DOM tree, we made a new reference in our array, then removed with .remove() and then removed from the array. Is there a better way to do this?

  • How do I stub a view in rspec-2

    - by Trey Bean
    I'm in the process of upgrading an app to Rails 3/Rspec 2. I see that stubbing a view helper method has changed in Rspec 2. It looks like instead of doing template.stub!, we're now supposed to do view.stub!, but I can't seem to get this to work on beta 10. I get an "undefined local variable or method `view' for # < RSpec::Core::ExampleGroup::Nested_1::Nested_1::Nested_1:0x106785fd0" error. I see that in this commit David removed the view method, but I can't figure out what it was replaced with. Something in ActionView::TestCase::Behavior? I'm on rails 3.0.0.beta3. Any idea what I'm missing?

  • Preview SMS format when sending email to SMS

    - by jarrett
    I'm using carrier-specific addresses to send email to SMS, which works fine. In reference to the answer of this question http://stackoverflow.com/questions/1179854/limitations-on-sms-messages-sent-using-free-email-sms-gateways is there any websites or other resources that list the format that is delivered for each carrier. ATT for example delivers the SMS with some added formatting that is not present with T-Mobile. I realize this is not a coding question, but since I can only see this question arising for someone that is creating email to SMS specific applications, it seems relevant to SO.

  • JavaScript Multi-Dimensional Arrays

    - by JasonS
    This wasn't the question I was going to ask but I have unexpectedly run aground with JavaScript arrays. I come from a PHP background and after looking at a few websites I am none the wiser. I am trying to create a multi-dimensional array. var photos = new Array; var a = 0; $("#photos img").each(function(i) { photos[a]["url"] = this.src; photos[a]["caption"] = this.alt; photos[a]["background"] = this.css('background-color'); a++; }); Error message: photos[a] is undefined. How do I do this? Thanks.

  • Streaming Video with Blackberry Simulator

    - by Jenny
    So, I wrote a quick little app for the iphone that takes in an http URL, and plays the .mp4 video located at that URL (it does more than that, of course, but that's the meat of it). Naturally, I wanted to have it on more than just a single mobile platform, so I decided to target Blackberry next. However, I'm running into a lot of problems with the Blackberry Environment. First of all, I learn that I can only download 256k files! I learn how to set that variable in my MDS simulator (and learn that this is NOT a production solution, because any end users will have to have their BES or MDS admin change the setting there). Then, I find a video less than 2 MB I can practice with. Going to the browser prompts me to save the video (rather than it playing in the browser like I expected). After saving the video, it refuses to play, saying it's the wrong format. So. I can't find a reference to IF Blackberry can stream with HTTP (i"ve heard it CAN use RTSP, though, and heard some rumors that it can't use HTTP, which would really suck). I also can't find a reference to what format blackberry uses (although I can find a million programs that will convert one file to the 'blackberry' format). Surely SOMEONE must have tried to stream video with the blackberry before. How did they go about doing so? Is it just a hopeless pipedream? Will I have to go with RTSP? Sorry for the lack of a concrete question...I'm just really lost, and I hate how so many tutorials or forum posts seem to assume I know the capabilities of the Blackberry... Edit: I finally found out that the .3gp (which I'd never heard of ) format is what Blackberry uses. Still have no idea how to stream videos off the web, though. I found a tutorial: http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How%5FTo%5F-%5FPlay%5Fvideo%5Fwithin%5Fa%5FBlackBerry%5Fsmartphone%5Fapplication.html?nodeid=1383173&vernum=0 That seemed to be useful, but the code doesn't work if you give it a URL (even though it claims it does).

  • How do I properly add the Kal framework to my iPhone project?

    - by BeachRunnerJoe
    I'm new to iPhone development and I'm having trouble using the 3rd part Kal framework in my project. I can't find any documentation on how to add the Kal framework to my code, so I assumed it was just a matter of adding the source files to my project's "Groups and Files" and set the Header file search path to include the new code. Is that all I need to do to properly add the Kal framework to my iPhone project? I'm getting this error (shown below), what is it indicating? Undefined symbols: ".objc_class_name_KalViewController", referenced from: literal-pointer@__OBJC@__cls_refs@KalViewController in RootViewController.o ld: symbol(s) not found I get this error when I add the statement... kalViewController = [[[KalViewController alloc] init] autorelease]; to my RootViewController.m viewDidLoad method and #import "Kal.h" Thanks so much for your help!
