• URL Controller Mapping Strategies (PHP)

  - by sunwukung

  This is kind of an academic question, so feel free to exit now. I've had a dig through Stack for threads pertaining to URL/Controller mapping in MVC frameworks - in particular this one: http://stackoverflow.com/questions/125677/php-application-url-routing So far, I can ascertain two practices: 1: dynamic mapping through parsing the URL string (exploded on '/') 2: pattern matching matching url to config file containing available routes I wanted to get some feedback (or links to some other threads/articles) from folks regarding their views on how best to approach this task.

• Why membership provider is not generic?

  - by Timmy O' Tool

  I have to confess that I hate membership provider. The default implementation is not very appropriate normally and I haven't seen so far a good implementation of a custom membership provider, probably because this is not possible :-) So the question is: In your opinion: which are the reasons for not having membership/role provider as a generic class? I mean, why Microsoft didn't selected this approach.

• Imagecache for non image CCKs?

  - by Marc Bria

  I'm creating a view with images, videos, audio and documents (books) and I like to shown a picture of each of them in a carousel. Everything works nicely with images and videos as far as we added a image-thumbnail (image filefield) to their CCK but we like to show a default image for audio and documents without changing the original CCK. Is it possible with imagecache (may be with imagecache_custom_code or views_custom_php) or we need to look for a different approach? Thanks for your help, m.

• How to determine who changed a file?

  - by Cocowalla

  In Windows, how can I programmatically determine which user account last changed or deleted a file? I know that setting up object access auditing may be an option, but if I use that I then have the problem of trying to match up event log entries to specific files... sounds messy! I can't think of any other way, so does anyone either have any tips for this approach or any alternatives?

• GDI+: Set all pixels to given color

  - by Charles

  What is the best way to set the RGB components of every pixel in a System.Drawing.Bitmap to a single, solid color? If possible, I'd like to avoid manually looping through each pixel to do this. Note: I want to keep the same alpha component from the original bitmap. I only want to change the RGB values. I looked into using a ColorMatrix or ColorMap, but I couldn't find any way to set all pixels to a specific given color with either approach.

• Entity Data Model Wizzard not creating tables in EDMX file

  - by Shawn

  I'm trying the database first approach by creating an ADO.NET Entity Data Model using the Wizard with the Adventureworks2012 DB. Testing DB connection works, and the connection string is added to the App.Config. I'm selecting all the tables except the ones marked as (dbo) AWBuildVersion, DatabaseLog, and ErrorLog. When the Wizard finishes the .edmx file is blank, and if I view the file in XML view the EntityContainer is empty. I'm using VS 2010 & .NET Framework 4.0

• ruby - find and replace in a string for commonly used street suffix

  - by go minimal

  The post office actually publishes a list of commonly used street suffixes in addresses: http://www.usps.com/ncsc/lookups/abbr_suffix.txt I want to take this list and make a ruby function that takes a string, takes the last word ("183 main strt".split[' '].last) and if it matches any of the commonly used street suffixes ("strt"), replace it with the official Postal Service Standard Suffix ("st"). Is there a better way to approach this than a massive str.sub.sub.sub.sub.sub?

• server performance: multiple external connections and performance

  - by websiteguru

  I am creating a php script that requires the server to make several cURL requests per run. I'll be running this script through cron every 3 minutes. Im looking to maximize the amount of cURL requests I can make in a 24 hr period. What I am wondering is if it would be better from a performance standpoint to get a dedicated server, or several small shared hosting accounts. With the problem being number of external connections and not system resources I'm wondering which is the best approach.

  - by swisstony

  I'm trying to develop an app using Django 1.1 on Webfaction. I'd like to get the IP address of the incoming request, but when I use request.META['REMOTE_ADDR'] it returns 127.0.0.1.

• Dynamically Rendering in a Scrollable Area

  - by James

  What is the generic algorithm or process that is commonly used to dynamically render portions of a scrolling area? For example, in Google Maps, when the user scrolls past the bounds of the currently rendered area, a grey checkerboard pattern is displayed within the not-yet-rendered portions while the application loads and renders those areas. I'm looking specifically for the approach, or the mathematics, related to filling a graphics area in chunks based on what has just come into view. If possible, I'm looking for anything relevant to the GDI+ process of doing so.
