  • What is the purpose of Finalization in java?

    - by Karthik
    Different websites are giving different opinions. My understanding is this: To clean up or reclaim the memory that an object occupies, the Garbage collector comes into action. (automatically is invoked???) The garbage collector then dereferences the object. Sometimes, there is no way for the garbage collector to access the object. Then finalize is invoked to do a final clean up processing after which the garbage collector can be invoked. is this right?

  • Optimizing a memoization decorator not increase call stack

    - by Tyler Crompton
    I have a very, very basic memoization decorator that I need to optimize below: def memoize(function): memos = {} def wrapper(*args): try: return memos[args] except KeyError: pass result = function(*args) memos[args] = result return result return wrapper The goal is to make this so that it doesn't add on to the call stack. It actually doubles it right now. I realize that I can embed this on a function by function basis, but that is not desired as I would like a global solution for memoizing. Any ideas?

    - by nobosh
    I have the following lines of JQUERY: // When dragging ends stop: function(event, ui) { // Replace the placeholder with the original $placeholder.after( $this.show() ).remove(); // Run a custom stop function specitifed in the settings settings.stop.apply(this); }, I don't want settings.stop.apply(this); to run UNTIL the line above is $placeholder.after( $this.show() ).remove();, right now what's happening is the settings.stop is running to early. With JQUERY, how can I Sequence these two lines to not proceed until the first is complete? Thanks

  • Can I have Entity Framework and Linq-to-SQL run together?

    - by Shnitzel
    Hi, I'd like to know if it's possible to have both Linq-to-SQL and Entity Framework running side-by-side. Our current configuration is Linq-to-SQL and we'd like to eventually move to EF. But there's just too much going on in the Linq-to-SQL side right now and we'd like to do it in phases. so any chance we can just start writing new stuff in entity framework but leave the older stuff running as is? And is it worth it? Thanks!

  • How to insert a SQLite record with a datetime set to 'now' in Android application?

    - by droidguy
    Say, we have a table created as: create table notes (_id integer primary key autoincrement, created_date date) To insert a record, I'd use ContentValues initialValues = new ContentValues(); initialValues.put("date_created", ""); long rowId = mDb.insert(DATABASE_TABLE, null, initialValues); But how to set the date_created column to "now"? To make it clear, the initialValues.put("date_created", "datetime('now')"); Is not the right solution. It just sets the column to "datetime('now')" text.

  • expand div with focus-jquery

    - by Joel
    Hi guys, I'm revisiting this after a few weeks, because I could never get it to work before, and hoping to now. Please look at this website-notice the newsletter signup form at the top right. http://www.rattletree.com I am wanting it to look exactly this way for now, but when the user clicks in the box to enter their email address, the containing div will expand (or simply appear) above the email field to also include a "name" and "city" field. I'm using jquery liberally in the sight, so that is at my disposal. This form is in the header so any id info, etc can't be withing the body tag... This is what I have so far: <div class="outeremailcontainer"> <div id="emailcontainer"> <?php include('verify.php'); ?> <form action="index_success.php" method="post" id="sendEmail" class="email"> <h3 class="register2">Newsletter Signup:</h3> <ul class="forms email"> <li class="email"><label for="emailFrom">Email: </label> <input type="text" name="emailFrom" class="info" id="emailFrom" value="<?= $_POST['emailFrom']; ?>" /> <?php if(isset($emailFromError)) echo '<span class="error">'.$emailFromError.'</span>'; ?> </li> <li class="buttons email"> <button type="submit" id="submit">Send</button> <input type="hidden" name="submitted" id="submitted" value="true" /> </li> </ul> </form> <div class="clearing"> </div> </div> css: p.emailbox{ text-align:center; margin:0; } p.emailbox:first-letter { font-size: 120%; font-weight: bold; } .outeremailcontainer { height:60px; width: 275px; background-image:url(/images/feather_email2.jpg); /*background-color:#fff;*/ text-align:center; /* margin:-50px 281px 0 auto ; */ float:right; position:relative; z-index:1; } form.email{ position:relative; } #emailcontainer { margin:0; padding: 0 auto; z-index:1000; display:block; position:relative; } Thanks for any help!

  • How can I disable mouse click event system wide using C#?

    - by mazzzzz
    Hey guys, I have a laptop with a very sensitive touch pad, and wanted to code a small program that could block the mouse input when I was typing a paper or something. I didn't think it would be hard to do, considering everything I've seen on low-level hooks, but I was wrong (astounding, right?). I looked at a few examples, but the examples I've seen either block both keyboard and mouse, or just hide the mouse. Any help with this would be great.

  • xslt or php for rendering output

    - by Arsenal
    I'm creating something where users can upload an xml and data get's imported to the database. Now I'm building some kind of a preview page where users will get to see how their input will look once it's stored. What would be the fastest (in execution time), using XSL to transform the xml to a html page, or using php to render the output? My guess is XSL is far more suitable (+ faster) for this (and by using a DTD there's no need for code written validation, right?)
