• How much more efficient is one big image rather than many small images. Facebook style.

  - by Jesse Gibbs

  So I was looking at the facebook HTML with firebug, and I chanced upon this image and came to the conclusion that facebook uses this large image (with tricky image positioning code) rather than many small ones for its graphical elements. Is this more efficient than storing many small images? Can anybody give any clues as to why facebook would do this.

• django flatpage redirects

  - by Joe

  I want to make sure all of my flatpages have the "www" subdomain and redirect to it if they don't. I've looked at some middlewares that redirect to www, but 1. they usually redirect all urls to www and 2. the ones I've found don't work with flatpages. I don't want all of my site urls to redirect to include the www subdomian, just the flatpages. Anyone know how I should go about doing this? Thanks

• Does Silverlight require the .NET framework to be installed?

  - by Mohit Deshpande

  I have been exploring the possibilities of Microsoft Silverlight and how it runs in web browsers. I just wonder if Silverlight requires the .NET framework? Meaning that Mac or Linux users cannot run Silverlight. I will be making the application using the .NET framework 3.5. Will this application run in any web browser, or just major ones like Internet Explorer, Firefox, or Safari?

  - by Stonkz

  What kind of frameworks / libraries are used to develop cross (console)-platform games, like ones that get released on Xbox 360 / PlayStation 3 at the same time? Or similarly, Xbox Live / PlayStation Network / WiiWare all at once? Surely such things are not freeware, but just... what are they in the first place?

• Netbeans IDE tutorials

  - by James P.

  I mostly use Eclipse but have mentionned Netbeans on my cv. Are there any good concise and up-to-date tutorials apart from the official ones that could bring me up to speed on how to use the IDE efficiently (shortcuts, debugging, views ...)? This excludes programming tutorials as I don't really need them unless there's a special manipulation involved.

  I'm trying to log URLs that access broken images, using an HTTP module to catch those images when accessed. How do you retrieve the URL where that image sits on? is there a way to do it the other way round too? That is, loop through images served in a URL and decide which ones are broken. This is all in ASP.NET with C#.

• Is there a (Linux) C++ IDE that can 'construct' a project from a makefile?

  - by Paul

  I am working on a legacy C app which uses makefiles. I am more comfortable (and more productive) working from within an IDE, so I am looking for an IDE that can import the makefile and create a project. Incidentally, these are hand written makefiles (not complicated ones like those generated by Autoconf). I am using Code::Blocks at the moment, but it seems it is unable to import makefiles ...

• Including different code for other home screen replacement screens

  - by radicam2

  I have put together a Skin for OpenHome but have since ran across AHome code for their IPhone theme and was wondering that if I included for AHome their Dock_Bg or widget_drawer among other things which is not on OpenHome that the Launcher for the respective screen replacement would just call the items it uses.I want to keep the mb as low as I can but reach more handsets.I can just make seperate ones but see many that include even Freshface as well as OpenHome and AHome.

• Cleaning up images in matlab

  - by Taegeuk

  How would you use Matlab to do the following? I've got fuzzy square images about the same size and then inside the fuzzy square there's smaller fuzzy squares, and I want to clean up the larger squares - not the smaller ones - so that they are no longer blurred. It looks like I'd have to make some type of morphological mask, but I'm not sure how in this case.

• How can I limit the number of registrants to an event?

  - by user356900

  I've set up a basic html/php submission form where people can register for our event, but need a way to replace the submission form webpage with one that reads something like "We have reached our registration limit" when we reach a certain number of submitted forms. Our database is MySQL (if that makes a difference) I've looked around on the web but people either say to count the entries by hand, or the ones that do have an automated system use CMS like drupal or joomla. Is it possible to setup an automated script that will do this?
