  • Redefine Object.defineProperty in Javascript

    - by kwicher
    I would like to learn if it is possible to redefine the "definePropery" function of the Object(.prototype) in a subclass(.prototype) so that the setter not only sets the value of the property but also eg executes an additional method. I have tried something like that: Myclass.prototype.defineProperty = function (obj, prop, meth) { Object.defineProperty.call(this, obj, prop, { get: function () { return obj[prop] }, set: function () { obj[prop] = n; alert("dev") } }) } But id does not work

    - by Adam Greenhall
    I installed Boost via sudo apt-get install libboost-all-dev on the most recent version of Ubuntu. Now I want to compile a project that uses the Boost.Serialization library, which needs to be linked. I've tried many variants of the following, without success: gcc -I /usr/lib code.cpp -o compiled /usr/lib/libboost_serialization.a and gcc -I /usr/lib code.cpp -o compiled -l libboost_serialization The error message is: error: ‘split_member’ is not a member of ‘boost::serialization ` What am I missing?

  • Code Promotion with Git

    - by draxter
    Hi, I'm trying to figure how can I use git for multiple environments (dev-test-prod) with code promotion. I read a bit about branching but didn't understand much how can this solve my problem since I must have the ability to run all of the environments concurrently and separately from each other. Will be very thankful for some kind of how-to.

  • Get all Vector2 Points Within Radius

    - by CheapDevotion
    I am looking for a formula that will give me all of the Vector2 Points within a certain radius given the center. Essentially what I am trying to do is change the color of each pixel in a 256 x 256 texture that is within a certain radius from a specific pixel (Using the Unity3d Game Engine). Programming Language doesn't really matter, as I can probably convert it to something I can use.

  • In-app settings controlled by plist?

    - by cannyboy
    Is there a library or good tutorial which covers creating in-app settings, like this: http://img.skitch.com/20090625-s8bf6ahybwe3cesd1id38h3nt.jpg What I would like is if it: doesn't use the built-in Settings app is controlled by a plist file with various Dictionaries and Arrays creates a nice looking table view allows text fields as well as switches and sliders and ticks etc doesn't have any of the annoying problems I've come across when trying to build my own version (not scrolling to show the textfield, cells disappearing) It would appear that the iphone dev world is crying out for such a thing. THANK YOU!

  • IE8 disappearing image bug

    - by Joe Fletcher
    In IE8 (& maybe others), when I leave my page to go to another tab in IE and then come back to my page's tab, each time the cursor runs over an image it disappears until I refresh the page. I've heard of disappearing image bugs, but I couldn't find anything on this particular case, especially given this isn't a weird pre-IE8 bug. I am using a lightbox, so possibly something to do with javascript? http://dev.bwmsnow.co.nz/snowboarding

  • What's the best way to display a blown-up image using minimal JQuery?

    - by TkTech
    The Goal: On mouseover (or :hover), enlarge the preview image by about 400% and display it in the center of the page Remove the preview when the mouse leaves The Problem: Solutions like FancyBox are too bloated in FancyBox's case it ignores width and height for image elements, which makes it useless Most of these "lightboxes" steal focus when they're called Really, I'm just looking for a simple, efficient solution. Oops - StackOverflow won't let me post images yet, mockup - http://img685.imageshack.us/img685/7649/idae.png

  • Get coordinates of beads covering the surface of a protein

    - by Hefeweizen
    Given a protein structure from the PDB, I would like to generate NS spheres of radius Rs which cover totally the protein surface. Given RS there, NS is the maximum number of spheres so they do not overlap. I would need the coordinates of the center of each sphere. Does anybody know if this has been implemented in some method / program? Or how to do it with scripting. Thanks

    I will admit that I am new to the tech/dev field. It seems to become a trend that every time I have to work with pdfs a part of me dies. Why is this format as ubiquitous as it seems to be? Is it just non-tech people that prefer pdfs?

  • IE is doing strange things with JQuery

    - by Syncopated
    So ... The thing is, the code works in FireFox, no problems. But when I open the same page, it gives me the following error: "Undefined is null or not an object." But when I copy the code to a localhost page, it works fine. Also when I clear my cache in IE it works, but only once, if I refresh after that one load, it gives me the same error. Here is the code: <script type="text/javascript" src="datepicker/js/jquery-1.4.2.min.js"></script> <script type="text/javascript"> var count3 = 0; var count5 = 0; var count2 = 0; var count4 = 0; $(document).ready(function(){ $('#switch3').click(function(){ $('#switchDiv3').slideToggle(350); if(count3 == 0){ count3 = 1; document.getElementById('switchImage3').src = "images/ArrowDown.png"; return; } else { count3 = 0; document.getElementById('switchImage3').src = "images/ArrowRight.png"; return; } }); ... (this is the code for each item that is generated) </script> And the code that determines the div that should hide: <table width="100%" border="0" cellspacing="0" cellpadding="0" align="center"> <tr> <td width="20" align="center" valign="top" style="padding-right: 3px"> <a style="cursor: pointer;" id="switch3"><img width="20" height="20" src="images/ArrowRight.png" id="switchImage3" style="border-style: solid; border-width: 1px; border-color: black;"/></a> </td> <td> <div id="switchDiv3"> <div align="left"> (Contents of the div here) </div> </div> </td> </tr> </table> Any help is appreciated! Thanks in advance
