• Erlang: configuring cover via rebar

  - by exterm

  My project is using a websocket server. Only for testing purposes, I also have an erlang websocket client implementation which resides in the test/ folder along with the tests. Now, when I run the tests via rebar with {cover_enabled, true} in my rebar.config, I also get coverage reported for the modules of the websocket client. I don't want this in my reports. Cover documentation says I should create a cover specification file containing {excl_mods, [websocket_client]}. But how do I convince rebar to use this file? Cover documentation: http://www.erlang.org/doc/apps/common_test/cover_chapter.html http://www.erlang.org/doc/man/cover.html rebar: https://github.com/basho/rebar

• Create a javascript chome extention that does not execute in 6 months

  - by user1907657

  I have just started learning programming and I would like to make a script into a chrome extension. Its a basic script and I hope to practice more and more and develop bigger projects and set myself bigger tasks This script has to do the following : reload a page every 20 seconds (say google.com) after 6 months the script must not run (maybe prompt a window saying "its over 6 months") The code should be able to go into a small chrome extension and also the 6 month time period should be absolute not relative to the time the script was started; for example should the browser crash and i have to turn on the extension again it should not restart the 6 month counter. Also if anyone could recommend any good sources for JavaScript to learn (preferably books; nothingIi read online ever seems to stick)

• How painful is a django project upload to a live (staging) site?

  - by Ignacio

  Hi, I've getting quite fast with a small django project of mine, which I'm developing locally, of course. But, as I had never worked with django before, I'm not aware of what it implies to upload it and test it on a production server. And I'm quite curious, since I'm very eager to test an early release live. I know there is this document, which I think it'll be really helpful: http://djangobook.com/en/2.0/chapter12/ But, are there any details I should take into account before, during and after the deployment? Any advice or best practices? Thanks.

• HTML, Javascript, PHP and Actionscript all in one Eclipse install (2010)

  - by ThunderChunky_SF

  I just wanted to poll the community and see which plugins people are currently using to get all of these different technologies running in Eclipse. I saw this thread which mentioned Spket & WPT: http://stackoverflow.com/questions/1575617/eclipse-which-plugins-for-html-javascript But I noticed that Spket doesn't seem to have been updated since October of 2009 so I'm wondering if it's still a good tool to use. I'm not sure what would be best for PHP since it seems like some of the tools are disjointed at the moment. For Actionscript I know I can just install the latest Flash Builder plugin and be done. Any suggestions are greatly appreciated.

• How to format an email address line (with name) with PHP?

  - by nbr

  I'm trying to generate email messages. The recipient's email address and name are specified by a user. What is the correct way to do this with PHP: $to_header = "To: $name <$email>" # incorrect! I already use a decent method for validating the email addressess (let's not go to that now...), but how do I properly encode $name with eg. QP when needed? For example, if the recipient is called "Foo Bär", I should produce (eg.) something like: To: =?utf-8?Q?Foo_B=C3=A4r?= <[email protected]>

• What is a cross-platform way to get the current directory?

  - by rubenvb

  I need a cross-platform way to get the current working directory (yes, getcwd does what I want). I thought this might do the trick: #ifdef _WIN32 #include <direct.h> #define getcwd _getcwd // stupid MSFT "deprecation" warning #elif #include <unistd.h> #endif #include <string> #include <iostream> using namespace std; int main() { string s_cwd(getcwd(NULL,0)); cout << "CWD is: " << s_cwd << endl; } I got this reading: _getcwd at MSDN getcwd at Kernel.org getcwd at Apple.com There should be no memory leaks, and is should work on a Mac as well, correct?

• ios - how do I concatinate strings to create a url?

  - by GeekedOut

  I am trying to make a url by first collecting the parameters, and then in one statement creating the actual url. Here is what I am trying to do: NSString *urlString = @"http://www.some_login_url.com?email=%@&password=%@"; NSString *email = self.email.text; NSString *password = self.password.text; NSString *url_to_send = [NSString stringWithFormat:@"%@%@", urlString , email , password]; So what I wanted to do was replace the @ symbols with the values in the variables, but instead the second variable just got appended to the end of the string. How would I change the last line so I could put the right parameters in their correct spots? Thanks!!

• Graphical Submit button doesn't 'post' in Firefox or IE

  - by Ken

  I've looked all over the net to try and solve this problem, but I can't find any solutions. So far, I've checked 3 different browsers. It does not work on IE or FireFox, but it works just fine in Safari. Here's the problem. When I click the button to submit my form, it forwards me to the 'post' URL page - INSTEAD of posting the data, and going to the thank you page like the script commands. Here's the code I'm working with: <form name="loginfrm" method="post" action="http://www.myaffiliatepowersite.com/members/quick_signup.php" style="margin:0; padding:0;"> " /

• Drupal, Views.. how to display views list + complete node, interactively ?

  - by Patrick

  hi, I'm using Views in Drupal to show node teasers. I would like now to show the complete node on the left side of my page, nearby the Views, and update it when the user click on a different teaser (better using AJAX). what's the best method to implement it. I was considering to use a lightbox, but it a bit complex (a lot of complications... such as parsing the content with javascript again.. etc). See screenshot: http://dl.dropbox.com/u/72686/viewsAndNode.png Thanks

• Maintaining Logging and/or stdout/stderr in Python Daemon

  - by dave mankoff

  Every recipe that I've found for creating a daemon process in Python involves forking twice (for Unix) and then closing all open file descriptors. (See http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/ for an example). This is all simple enough but I seem to have an issue. On the production machine that I am setting up, my daemon is aborting - silently since all open file descriptors were closed. I am having a tricky time debugging the issue currently and am wondering what the proper way to catch and log these errors are. What is the right way to setup logging such that it continues to work after daemonizing? Do I just call logging.basicConfig() a second time after daemonizing? What's the right way to capture stdout and stderr? I am fuzzy on the details of why all the files are closed. Ideally, my main code could just call daemon_start(pid_file) and logging would continue to work.

• Method sscanf() ambiguous behavior

  - by Carmen Cojocaru

  I am trying to understand how sscanf() works. I ran some examples from this page: http://docs.roxen.com/pike/7.0/tutorial/strings/sscanf.xml and they don't work on my platform. I can't understand why. For instance: "sscanf("4711bar", "%d%s", a, b);" makes the program exit with an error... Here is one of the examples that work: "sscanf("foo", "f%s", a);". Does anybody know why? Do they work on your platforms? Thank you. This is my code: int main(void){ char *b = (char*)malloc(sizeof(char)*100); int a = 0; sscanf("4711bar", "%d%s", a, b); printf("%d", a); printf("%s", b); }

• Stretch image to fill div, but not skew

  - by z0mbieParade

  I'm trying to make an image stretch to fit inside a div. However I want it to overflow so that the entire div is filled. The div resizes with the page. I want an effect similar to the jQuery bgstretcher plugin (http://www.ajaxblender.com/bgstretcher-2-jquery-stretch-background-plugin-updated.html) , but I cannot use that plugin because I'm already using it for the background image on the page, and it seems to not work when you try and activate multiple instances of it. So what I'm asking is for some sort of simple jQuery function that resizes an image to completely fill a div with overflow hidden, so that there are no gaps, but without skewing the image. Edit: http://jsfiddle.net/R7UCZ/ That's sort of what I'm after, but I want the image to fill the entire div without skewing. If the image goes out of the div a bit, that's fine, but I need it to resize with the div, which resizes with the page, both height and width.

• Overlapping elements stop overlapping in IE7 on class change

  - by Gazzer

  On this page http://zenchan.com/program/ When I rollover the right box 2nd from the top suddenly the overlapping (negative margin disappears). What's happening is that a 'hover' class is being added to shift the background sprite. The two yellow boxes are debugging: if the hover class is put their in advance there is no problem. So fundamentally the CSS is not a problem for IE7 but adding the class is. Any ideas what's causing this. I've tried adding haslayout to various elements but to little effect.

• Pass value to an include file in php.

  - by Muhammad Sajid

  Hi, How do you pass a parameter into an include file? I tried the following but it doesn't work. include "myfile.php?var=123"; and in myfile.php, I try to retrieve the parameter using $_GET["var"]. include "myfile.php?var=123"; will not work. PHP searches for a file with this exact name and does not parse the parameter for that I also did this: include "http://MyGreatSite.com/myfile.php?var=123";but it does not also work. Any hints? Thanks.
