• How to compile a program which needs a newer version of glib

  - by michael

  Hi, I am trying to compile Webkit on Ubuntu 8.04. But when i run autogen.sh, I get the following error saying it needs a newer version of glib. So what is the safest way to install glib without screwing up the rest of my OS (since the rest needs 2.16 while webkit compile needs 2.21)? checking for GLIB... configure: error: Package requirements (glib-2.0 >= 2.21.3 gobject-2.0 >= 2.0 gthread-2.0 >= 2.0) were not met: Requested 'glib-2.0 >= 2.21.3' but version of GLib is 2.16.6 Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GLIB_CFLAGS and GLIB_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.

• Embedding Youtube Videos on user's wall with the Javascript API

  - by dragonmantank

  I'm attempting to embed a Youtube video on a user's wall using the Javascript API. I've poured over a bunch of different tutorials and came up with this: var data = { method: 'feed', link: current_video_url, // Link to the vide on our site source: current_video_src, // Link to the Youtube video, http://youtube.com/v/[hash] picture: current_picture_url, // Thumbnail from youtube title: current_video_title, // Title from our page caption: current_video_description // Text from our page } FB.ui(data); Running the Facebook Debugger shows that the current_video_url link is being properly parsed for OG tags and is available as an embedded video. I ran a debugger and all the variables are being properly set in the data variable. This worked fine for about 2 days, and then we pushed the site live. We set up a new AppID in Facebook but now all the videos are just thumbnails instead of being embedded in the user's wall. I thought maybe this is a problem with the live site but now the dev site is broken too. What's the best way to get this to work consistently?

  - by Anish Karunakaran

  In my scenario am using java script popup that popups another form Which is an address Entry form of merely 20 Controls in it.

• Where does complexity bloat from?

  - by AareP

  Many of our design decisions are based on our gut feeling about how to avoid complexity and bloating. Some of our complexity-fears are true, we have plenty of painful experience on throwing away deprecated code. Other times we learn that some particular task isn't really that complex as we though it to be. We notice for example that upkeeping 3000 lines of code in one file isn't that difficult... or that using special purpose "dirty flags" isn't really bad OO practice... or that in some cases it's more convenient to have 50 variables in one class that have 5 different classes with shared responsibilities... One friend has even stated that adding functions to the program isn't really adding complexity to your system. So, what do you think, where does bloated complexity creep from? Is it variable count, function count, code line count, code line count per function, or something else?

• Call method with parameters after animation completion

  - by Jean

  I want to call a method with certain parameters once an animation is done. The flow is something like this: -(void) myMethod:(int)val { [self performAnimation]; [self doSomethingElse:val]; // This should be done after animation completion } I presume the 'doSomethingElse' method needs to be called from the method defined in 'setAnimationDidStopSelector' - or is there a way to have the animation block until done? What is the best way to let the method called on 'setAnimationDidStopSelector' know about the method it needs to call and its parameter? Can this be done with selectors? Or is the only way of doing this by storing the methods and its params in class temp variables and access them when needed?

• Equivalent of describeType for Flex Component EVENTS

  - by Joshua

  Using "introspection" In Flex I can say: var classInfo:XML=describeType(SomeObject); Which will list for me the Accessors, Methods And Variables. (http://livedocs.adobe.com/flex/3/html/help.html?content=usingas_8.html) But what is the equivalent to programmatically inspect all of an object's possible EVENTS? (NOT JUST the events for which event listeners have been set, but to somehow step through a list of all VALID EVENTS for which event listeners may POTENTIALLY be set -- I realize that such lists are readily available online, and that's great for cases when I know the object's type at design type, but I require some way to inspect any given displayobject programmatically at runtime, and determine what events, if any, are or may be associated with it.)

• $.(ajax) wrapper for Jquery - passing parameters to delegates

  - by gnomixa

  I use $.(ajax) function extensively in my app to call ASP.net web services. I would like to write a wrapper in order to centralize all the ajax calls. I found few simple solutions, but none address an issue of passing parameters to delegates, for example, if i have: $.ajax({ type: "POST", url: "http://localhost/TemplateWebService/TemplateWebService/Service.asmx/GetFoobar", data: jsonText, contentType: "application/json; charset=utf-8", dataType: "json", success: function(response) { var results = (typeof response.d) == 'string' ? eval('(' + response.d + ')') : response.d; OnSuccess(results, someOtherParam1, someOtherParam2); }, error: function(xhr, status, error) { OnError(); } }); The wrapper to this call would have to have the way to pass someOtherParam1, someOtherParam2 to the OnSuccess delegate...Aside from packing the variables into a generic array, I can't think of other solutions. How did you guys address this issue?

• Remove index.php in CodeIgniter

  - by Gabriel Bianconi

  Hello. I'm trying to remove the 'index.php' from CI Urls. I've tried many solutions, none of them worked. I've already set these variables in 'config.php': $config['index_page'] = ""; $config['uri_protocol'] = "REQUEST_URI"; And my current .htaccess is: Options +FollowSymLinks RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} ^plugb.com$ [NC] RewriteRule ^(.*)$ http://www.plugb.com/$1 [R=301,L] RewriteCond $1 !^(index\.php|files|robots\.txt) RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1 [L,QSA] The www prefix part works fine. But the 'index.php' part doesn't. If you want to check the webpage, here is it: http://www.plugb.com/index.php/home

• Is there a better way to create an object-oriented class with jquery?

  - by Devon

  I use the jquery extend function to extend a class prototype. For example: MyWidget = function(name_var) { this.init(name_var); } $.extend(MyWidget.prototype, { // object variables widget_name: '', init: function(widget_name) { // do initialization here this.widget_name = widget_name; }, doSomething: function() { // an example object method alert('my name is '+this.widget_name); } }); // example of using the class built above var widget1 = new MyWidget('widget one'); widget1.doSomething(); Is there a better way to do this? Is there a cleaner way to create the class above with only one statement instead of two?

• Code editor with autocomplete

  - by Andrey

  I need to create a code editor for my own simple language: className.MethodName(parameterName = 2, ... ) I've created the appropriate grammar and autogenerate parser using ANTLR tool. Now I would like to have an autocomplete for class, method, variables and parameter names. This list should be context dependent, f.e. for "class." it should display methods and for "class.Method(" - parameters. I was going to parse the text and display the list depending on in which node the cursor is. The problem is that for incomplete code like "aaa.bbb(" the parser produces an error instead of a syntax tree. Any idea how to solve this problem? Maybe I'm on the wrong way and I shouldn't parse code to display autocomplete?

• How do I access a asp.net session variable from APP_CODE??

  - by user313714

  I have seen lots of posts here and elsewhere stating that one can access session variables from app_code. I want to access an already created session. this code errors out because of a null exception. string myFile = HttpContext.Current.Session["UploadedFile"]; this creates a null session variable. System.Web.SessionState.HttpSessionState Session = HttpContext.Current.Session; It looks like I can create a new session variable but not access an already created one. Anyone have any idea what might be giving me problems?

• Two '==' equality operators in same 'if' condition are not working as intended.

  - by Manav MN

  I am trying to establish equality of three equal variables, but the following code is not printing the obvious true answer which it should print. Can someone explain, how the compiler is parsing the given if condition internally? #include<stdio.h> int main() { int i = 123, j = 123, k = 123; if ( i == j == k) printf("Equal\n"); else printf("NOT Equal\n"); return 0; } Output: manav@workstation:~$ gcc -Wall -pedantic calc.c calc.c: In function ‘main’: calc.c:5: warning: suggest parentheses around comparison in operand of ‘==’ manav@workstation:~$ ./a.out NOT Equal manav@workstation:~$ EDIT: Going by the answers given below, is the following statement okay to check above equality? if ( (i==j) == (j==k))

• A specific string format with a number and character together represeting a certain item

  - by sil3nt

  Hello there, I have a string which looks like this "a 3e,6s,1d,3g,22r,7c 3g,5r,9c 19.3", how do I go through it and extract the integers and assign them to its corresponding letter variable?. (i have integer variables d,r,e,g,s and c). The first letter in the string represents a function, "3e,6s,1d,3g,22r,7c" and "3g,5r,9c" are two separate containers . And the last decimal value represents a number which needs to be broken down into those variable numbers. my problem is extracting those integers with the letters after it and assigning them into there corresponding letter. and any number with a negative sign or a space in between the number and the letter is invalid. How on earth do i do this?

• How can Perl interact with an ajax form

  - by Jeff

  I'm writing a perl program that was doing a simple get command to retrieve results and process them. But the site has been updated and now has a java component that handles the results (so the actual data is not in the source code anymore). This is the site: http://wro.westchesterclerk.com/legalsearch.aspx Try putting in: Index Number: 11103 Year: 2009 I want to be able to pro grammatically enter the "index number" and "year" at the bottom of the form where it says "search by number" and then retrieve the results listed next to it. I've written many programs in Perl that simply pass variables via the URL and the results are listed in the source code, so it's easy to parse. (Using LWP:Simple) Like: $html = get("http://www.url.com?id=$somenum&year=$someyear") But this is totally new to me and I don't know where to begin. I'm somewhat familiar with LWP:UserAgent and Mechanize. I'd really appreciate any help. Thanks!

• Can't run jUnit with Eclipse

• Objective-C : enum like Java (int values and many others for each enum)

  - by Oliver

  In Java, you can make an enum having multiples values. In objective-C, this cannot be done easily. I've read many pages about this but I didn't found anything satisfying that would allow me to use enums by a simple way and to keep the enum declaration and their different values in the same file. I would like to write something like this in a enums.h : // ======================================== typedef enum {eRED, eGREEN, eBLUE} ColorEnum; int colorValues[] = { 0xFF0000, 0x00FF00, 0x0000FF }; NSArray *colorNames = [NSArray arrayWithObjects:@"Red color", @"light green", @"Deep blue", nil]; // ======================================== and be able to use thoses global variables to manage my stuff anywhere like : int color = colorValues[eRED]; But I don't know how to write this. I have compile errors like "ColorValues" is defines many times. Or if I just use "static", I have many "ColorValues" not used in .m file... Could you help me ?

• R counting the occurance of similar rows of data frame

  - by Matt

  I have data in the following format called DF (this is just a made up simplified sample): eval.num, eval.count, fitness, fitness.mean, green.h.0, green.v.0, offset.0 random 1 1 1500 1500 100 120 40 232342 2 2 1000 1250 100 120 40 11843 3 3 1250 1250 100 120 40 981340234 4 4 1000 1187.5 100 120 40 4363453 5 1 2000 2000 200 100 40 345902 6 1 3000 3000 150 90 10 943 7 1 2000 2000 90 90 100 9304358 8 2 1800 1900 90 90 100 284333 However, the eval.count column is incorrect and I need to fix it. It should report the number of rows with the same values for (green.h.0, green.v.0, and offset.0) by only looking at the previous rows. The example above uses the expected values, but assume they are incorrect. How can I add a new column (say "count") which will count all previous rows which have the same values of the specified variables? I have gotten help on a similar problem of just selecting all rows with the same values for specified columns, so I supposed I could just write a loop around that, but it seems inefficient to me.

• Best practices for querying an entire row in a database table? (MySQL / CodeIgniter)

  - by Walker

  Sorry for the novice question! I have a table called cities in which I have fields called id, name, xpos, ypos. I'm trying to use the data from each row to set a div's position and name. What I'm wondering is what's the best practice for dynamically querying an unknown amount of rows (I don't know how many cities there might be, I want to pull the information from all of them) and then passing the variables from the model into the view and then setting attributes with it? Right now I've 'hacked' a solution where I run a different function each time which pulls a value using a query ('SELECT id FROM cities;'), then I store that in a global array variable and pass it into view. I do this for each var so I have arrays called: city_idVar, city_nameVar, city_xposVar, city_yposVar then I know that the city_nameVar[0] matches up with city_xposVar[0] etc. Is there a better way?

• pasteHTML removes markup

  - by ullmark

  I am writing a plugin to an old IE-only WYSIWYG-editor which resides in an old CMS. I've created a plugin that opens an popup where the user kan enter the url of an youtube clip. The popup then creates the corrent <object..><param..> markup for the embed and uses Internet Explorers pasteHTML function; var range = plugin.editorDocument.selection.createRange(); var embedHtml = OpenDialog(dialogUrl, null, 400, 200); if (!embedHtml) { return; } range.pasteHTML(embedHtml); I know it's missing a bit of information about some of the variables but you get the picture. The problem is that the <param>-tags gets removed when i run the pasteHTML. I wonder if anyone have an idea of fixing this, and letting me keep my param-tags

• How to allow multiple inputs from user using R?

  - by Juan

  For example, if I need that the user specifies the number of rows and columns of a matrix: PROMPT: Number of rows?: USER INPUT: [a number] I need that R 'waits' for the input. Then save [a number] into a variable v1. Next, PROMPT: Number of columns?: USER INPUT: [another number] Also save [another number] into a variable v2. At the end, I will have two variables (v1, v2) that will be used in the rest of the code. "readline" only works for one input at a time. I can't run the two lines together v1 <- readline("Number of rows?: ") v2 <- readline("Number of columns?: ") Any ideas or suggestions? Thank you in advance

• How do I protect myself?

  - by ved

  I was poking around at my work computer this evening and was looking at my timesheets. I noticed that all my timesheets had variables in the URLs and I could figure out the numbering scheme for the pages. Then I got a little curious about SQL injection and thought of trying out adding simple SQL injections like "OR 1=1" etc. to see how protected we really were with our timesheet info. One of these strings yielded a friendly error page saying that an error email was sent to the developer. I am concerned that my ID, and request will be seen by the developer , immediately recognized as SQL injection and will be reported to network security officer as a malicious attempt by an employee to hack the timesheet dB. what is my defense? I am really worried.
