• Why do garbage collectors freeze execution?

  - by Martin

  I was thinking about garbage collection on the way home, and I began wondering, why does the garbage collector totally freeze execution of a program? Personally I would have designed it to block any threads which try to allocate a new object, but threads which were running would be left alone. I can't imagine any situation where this would be a problem compared to how a garbage collector currently works.

• Are event handlerss in JavaScript called in order?

  - by musicfreak

  I know this is a simple question, but I haven't had the chance to test it in any browser other than Firefox. If I attach multiple event handlers to a single event on a single DOM element, are the event handlers guaranteed to be called in the order they were added? Or should I not rely on this behavior?

• Want to show <embed> and <object> tags from YUI editor as a text rather then a video.

  - by user208678

  I am using YUI rich text editor on my website (php/mysql), so that a user may enter textual matter/articles through it. But if a user copies and paste some embed code in the textarea, from any video sites like youtube, it should get saved as a text block and not as a playing video when showing the text content on the browser. Now YUI automatically converts the characters into html entities which ever is needed. Please note that if I put a new line in the yui editor (by pressing "Enter" key), it will be converted into a "<br>" tag in the background and this will not get html entity encoded when passing the value to my backend PHP script. But If I copy and paste any embed tag or for that reason any valid html tags in the textarea, it will be html entity encoded by YUI. Now to support UTF-8 characters, I am using a function (DBVarConv) in my php script before saving it into my database. The code for the function is given below function DBVarConv($var,$isEncoded = false) { if($isEncoded) return addslashes(htmlentities($var, ENT_QUOTES, 'UTF-8', false)); else return htmlentities ($var, ENT_QUOTES, 'UTF-8', false); } $myeditorData = DBVarConv($myeditorData, true); // Save $myeditorData in database. While showing the data in the browser, I am using another function called "smart_html_entity_decode". The code is given below. function smart_html_entity_decode($text, $isAddslashesUsed = false) { if($isAddslashesUsed) $tmp = stripslashes(html_entity_decode($text, ENT_QUOTES, 'UTF-8')); else $tmp = html_entity_decode($text, ENT_QUOTES, 'UTF-8'); if ($tmp == $text) return $tmp; return smart_html_entity_decode($tmp, $isAddslashesUsed); } // Get $myData from database $myData=smart_html_entity_decode($myData, true); echo $myData; The problem is that in doing so, it is also decoding the embed and object tags from their html encoded entities and as a result my obejct tags are shown as a video and not as a simple text. Try using the text editor at tumblr.com. If you paste an embed code in the editor, it will be shown as a text block not as a video. I am trying to build the same functionality on my website with UTF-8 support. Any help will be highly appreciated.

• How to create constant NSString by concatenating strings in Obj-C ?

  - by eric-morand

  Hi guys, I'm trying to instanciate a constant NSString by concatanating other NSString instances. Here is what I'm doing in my implementation file : static NSString *const MY_CONST = @"TEST"; static NSString *const MY_CONCATENATE_CONST = [NSString stringWithFormat:@"STRING %@", MY_CONST]; It leads to the following compilation error : Initializer element is not constant I suppose this is because stringWithFormat doesn't return a constant NSString, but since there is no other way to concatenate strings in Obj-C, what am I supposed to do ? Thanks for your help, Eric.

• Web pages show empty band across the top

  - by Gerry

  In Chrome, site http://www.helpinghandspeople.com has a 16px empty band (background colour shows) across the top of the page. It's not supposed to be there, but I can't figure out how to make it go away. In Firefox, the home page shows fine, but login and a few other pages show a 24px band. Viewing source and running inspect element are not helpful. Does anyone have a suggestion where to look? Thanks Gerry

We are evaluating some FW which will allow us to build dynamic pages, dynamic as in, deciding at runtime what user controls will be displayed and in what order. Also possibly, the pages and order in which they will be displayed. We are looking at Page Flow Application Block, but there's limited documentation around it, we were interested in knowing what other options could be considered. Thanks for your help guys...

• Event on HTML selection

  - by jldupont

  Is there an event for situations where something is selected on an HTML page like arbitrary text within a span element?

• How do I store multiple copies of the same field in Django?

  - by Alistair

  I'm storing OLAC metadata which describes linguistic resources. Many of the elements of the metadata are repeatable -- for example, a resource can have two languages, three authors and four dates associated with it. Is there any way of storing this in one model? It seems like overkill to define a model for each repeatable metadata element -- especially since the models will only have one field: it's value.

  - by Shaun F

  Is there a way to setup apache and tomcat so that I can have d1.webapp.com d2.webapp.com d3.webapp.com etc. All hosted by the same tomcat instance without having to add aliases to the HOSTS element in the tomcat config file? I will be allowing new users to have thier own domain when they sign up and it will be a subdomain of the web app. I don't want to keep updating the hosts file for aliases and restarting tomcat though each time a new user signs up.

  Hello, I'm writing a program in python using dbus that detects inserted usb drives and manipulates the files inside of them.
