  • Data store for capturing votes & aggregating them

    - by Nathan de Vries
    I'm interested in using Node.js as a socket server for stream-based communication with tens of thousands of clients. Clients will be sending votes for particular pieces of content, and receiving near-realtime updates of aggregated vote tallies from the server. The datastore needs to support: Storing the votes Summarising the votes in near-realtime Preventing multiple votes within an arbitrary time period (e.g. clients can only vote once for a piece of content every 1 minute) Something that already has client libraries for Node.js would be preferable.

  • Can I tweak a page's appearance using Google Chrome's developer tools?

    - by Nathan Long
    When I'm working on a web page layout, I often use Firefox and Firebug to tweak the CSS until it looks right, then modify my style sheet to match. Right now, I'm trying to fix something that looks fine in other browsers but wrong in Google Chrome. I have pulled up Chrome's Developer Tools, and can inspect the computed style, but don't see a way to edit values and see the results on my page. Is there a way to do this?

  • iframe as scriptaculous droppable

    - by Nathan
    I have a sortable list and an iframe on the same page. What I'm trying to do is define the <iframe> as a Droppable. Everything works with out errors but when I try to drag a sortable item across the Iframe it stops at the edge. ( if I move it slowly it seems works in firefox) The Iframe is set to DesignMode ="on" so covering it with a transparent element to act as the droppable does not seem applicable here. Anyone know of any other solutions or a better way to handle this?

  • Drag and Drop to a Powershell script

    - by Nathan Hartley
    I thought I had an answer to this, but the more I play with it, the more I see it as a design flaw of Powershell. I would like to drag and drop (or use the Send-To mechanism) to pass multiple files and/or folders as a array to a Powershell script. Test Script #Test.ps1 param ( [string[]] $Paths, [string] $ExampleParameter ) "Paths" $Paths "args" $args I then created a shortcut with the following command line and dragged some files on to it. The files come across as individual parameters which first match the script parameters positionally, with the remainder being placed in the $args array. Shortcut Attempt 1 powershell.exe -noprofile -noexit -file c:\Test.ps1 I found that I can do this with a wrapper script... Wrapper Script #TestWrapper.ps1 & .\Test.ps1 -Paths $args Shortcut Attempt 2 powershell.exe -noprofile -noexit -file c:\TestWrapper.ps1 Has anyone found a way to do this without the extra script?

  • Create window as child in third party application.

    - by Nathan W
    I'm trying to get my C# form to be parented correctly in a third party app, I have the handle to the control that I would like my form parented to but just can't seem to get it to work. I would like to create my form so that it is part of the MDIClient, handle 005E0ED6. Just like Window 01D7157D. Is this possible? If so can it be done in C#?

  • How can I use aliased commands with xargs?

    - by Nathan Fellman
    I have the following alias in my .aliases: alias gi grep -i and I want to look for foo case-insensitively in all the files that have the string bar in their name: find -name \*bar\* | xargs gi foo This is what I get: xargs: gi: No such file or directory Is there any way to use aliases in xargs, or do I have to use the full version: find -name \*bar\* | xargs grep -i foo Note: This is a simple example. Besides gi I have some pretty complicated aliases that I can't expand manually so easily. Edit: I used tcsh, so please specify if an answer is shell-specific.

There is any real example to use IMAGE?

  • jQuery image preload/cache halting browser

    - by Nathan Loding
    In short, I have a very large photo gallery and I'm trying to cache as many of the thumbnail images as I can when the first page loads. There could be 1000+ thumbnails. First question -- is it stupid to try to preload/cache that many? Second question -- when the preload() function fires, the entire browser stops responding for a minute to two. At which time the callback fires, so the preload is complete. Is there a way to accomplish "smart preloading" that doesn't impede on the user experience/speed when attempting to load this many objects? The $.preLoadImages function is take from here: http://binarykitten.me.uk/dev/jq-plugins/107-jquery-image-preloader-plus-callbacks.html Here's how I'm implementing it: $(document).ready(function() { setTimeout("preload()", 5000); }); function preload() { var images = ['image1.jpg', ... 'image1000.jpg']; $.preLoadImages(images, function() { alert('done'); }); } 1000 images is a lot. Am I asking too much?

  • Why does Chrome ignore local jQuery cookies?

    - by Nathan Long
    I am using the jQuery Cookie plugin (download and demo and source code with comments) to set and read a cookie. I'm developing the page on my local machine. The following code will successfully set a cookie in FireFox 3, IE 7, and Safari (PC). But if the browser is Google Chrome AND the page is a local file, it does not work. $.cookie("nameofcookie", cookievalue, {path: "/", expires: 30}); What I know: The plugin's demo works with Chrome. If I put my code on a web server (address starting with http://), it works with Chrome. So the cookie fails only for Google Chrome on local files. Possible causes: Google Chrome doesn't accept cookies from web pages on the hard drive (paths like file:///C:/websites/foo.html) Something in the plugin implentation causes Chrome to reject such cookies Can anyone confirm this and identify the root cause?

  • Where do I find a list of changes and bug fixes for .Net classes from 3.5 -> 4.0?

    - by Nathan Ridley
    I'm having trouble finding a list of the changes and bug fixes that have been made in the .Net framework for .Net 4.0. They're not easy to find, but surely they exist somewhere? Specifically I want to find out what changes and updates have been made for System.Net.HttpWebRequest and System.Net.CookieContainer, as both are quite bugridden in 3.5 and I want to evaluate whether I should write my code for .Net 4.0 or if I should create some custom classes to work around their issues.

  • Can't create an OgreBullet Trimesh

    - by Nathan Baggs
    I'm using Ogre and Bullet for a project and I currently have a first person camera set up with a Capsule Collision Shape. I've created a model of a cave (which will serve as the main part of the level) and imported it into my game. I'm now trying to create an OgreBulletCollisions::TriangleMeshCollisionShape of the cave. The code I've got so far is this but it isn't working. It compiles but the Capsule shape passes straight through the cave shape. Also I have debug outlines on and there are none being drawn around the cave mesh. Entity *cave = mSceneMgr->createEntity("Cave", "pCube1.mesh"); SceneNode *caveNode = mSceneMgr->getRootSceneNode()->createChildSceneNode(); caveNode->setPosition(0, 10, 250); caveNode->setScale(10, 10, 10); caveNode->rotate(Quaternion(0.5, 0.5, -0.5, 0.5)); caveNode->attachObject(cave); OgreBulletCollisions::StaticMeshToShapeConverter *smtsc = new OgreBulletCollisions::StaticMeshToShapeConverter(); smtsc->addEntity(cave); OgreBulletCollisions::TriangleMeshCollisionShape *tri = smtsc->createTrimesh(); OgreBulletDynamics::RigidBody *caveBody = new OgreBulletDynamics::RigidBody("cave", mWorld); caveBody->setStaticShape(tri, 0.1, 0.8); mShapes.push_back(tri); mBodies.push_back(caveBody); Any suggestions are welcome. To clarify. It compiles but the Capsule shape passes straight through the cave shape. Also I have debug outlines on and there are none being drawn around the cave mesh

  • Pattern matching in Perl ala Haskell

    - by Paul Nathan
    In Haskell (F#, Ocaml, and others), I can do this: sign x | x > 0 = 1 | x == 0 = 0 | x < 0 = -1 Which calculates the sign of a given integer. This can concisely express certain logic flows; I've encountered one of these flows in Perl. Right now what I am doing is sub frobnicator { my $frob = shift; return "foo" if $frob eq "Foomaticator"; return "bar" if $frob eq "Barmaticator"; croak("Unable to frob legit value: $frob received"); } Which feels inexpressive and ugly. This code has to run on Perl 5.8.8, but of course I am interested in more modern techniques as well.

  • NSDocument Subclass not closed by NSWindowController?

    - by Nathan Douglas
    Okay, I'm fairly new to Cocoa and Objective-C, and to OOP in general. As background, I'm working on an extensible editor that stores the user's documents in a package. This of course required some "fun" to get around some issues with NSFileWrapper (i.e. a somewhat sneaky writing and loading process to avoid making NSFileWrappers for every single document within the bundle). The solution I arrived at was to essentially treat my NSDocument subclass as just a shell -- use it to make the folder for the bundle, and then pass off writing the actual content of the document to other methods. Unfortunately, at some point I seem to have completely screwed the pooch. I don't know how this happened, but closing the document window no longer releases the document. The document object doesn't seem to receive a "close" message -- or any related messages -- even though the window closes successfully. The end result is that if I start my app, create a new document, save it, then close it, and try to reopen it, the document window never appears. With some creative subclassing and NSLogging, I managed to figure out that the document object was still in memory, and still attached to the NSDocumentController instance, and so trying to open the document never got past the NSDocumentController's "hmm, currently have that one open" check. I did have an NSWindowController and NSDocumentController instance, but I've purged them from my project completely. I've overridden nearly every method for NSDocument trying to find out where the issue is. So far as I know, my Interface Builder bindings are all correct -- "Close" in the main menu is attached to "performClose:" of the First Responder, etc, and I've tried with fresh unsullied MainMenu and Document xibs as well. I thought that it might be something strange with my bundle writing code, so I basically deleted it all and started from scratch, but that didn't seem to work. I took out my init method overrides, and that didn't help either. I don't have the source of any simple document apps here, so I didn't try the next logical step (to substitute known-working code for mine in the readfromurl and writetourl methods). I've had this problem for about sixteen hours of uninterrupted troubleshooting now, and needless to say, I'm at the end of my rope. If I can't figure it out, I guess I'm going to try the project from scratch with a lot more code and intensity based around the bundle-document mess. Any help would be greatly appreciated.

  • Fullcalendar jquery plugin Show years on nextYear buttons

    - by Nathan Neff
    I'm using the fullcalendar jquery plugin, and would like to display 2009 and 2011 in the nextYear and prevYear buttons. For exmaple: 2009 May 2010 2011 I know I can put static text on the buttons like this: buttonText: { prevYear: '2009', nextYear: '2011' }, But I would like those years to change, depending on the year that the calendar is currently viewing. There's documentation about 'year' here: http://arshaw.com/fullcalendar/docs/current_date/ but I don't know how to get that 'year' property. Any examples would be appreciated, Thanks, --Nate
