• Difference between URI and URL

  - by Sarfraz

  If you read the documentation of CodeIgniter or Kohana, there is a lot of confusion about the usage of URI and URL. Sometimes they use one and other times the other. They also incorporate URI class which makes it easier working with URLs. I know that: URI stands for Uniform Resource Identifier URL stands for Uniform Resource Locator But that doesn't make much sense. What exactly is the difference? or are they same?

  - by xyzzy

  I have a bunch of images that are in a hidden div. The div is shown when the user clicks on some links.

• OSX Weak Linking - check if a class exists and use that class

  - by psychotik

  I'm trying to create a universal iPhone app, but it uses a class defined only in a newer version of the SDK. The framework exists on older systems, but a class defined in the framework doesn't.

  Is the iTunes COM interface available on Mac OS/X? From the documentation I could find, it seems much more extensive than the Applescript interface I could expose through the Automator program. Disclaimer: absolute OS/X newbie here.

• Custom Map using iPhone MapKit

  - by DHamrick

  I am attempting to use MapKit to create a custom map (similar to this concept http://mapwow.com/) using an image instead of the google maps image. This is so we can include the gps functionality and the pins functionality. I have looked in the documentation and there does not appear to be a standard way of doing it. Is there a way to do this using MapKit or has someone found a way to achieve something similar?

  - by Eric J.

  According to the Spring documentation, By default, the dm Server trace file is called $SERVER_HOME/serviceability/logs/dm-server/log_i.log ... The index i varies from 1 to 4, on a rolling basis, as each log file exceeds 10Mb. I'm aware that the default trace file name can be changed in server.config. Is it possible to change the number of log files that are kept before rolling over and/or the maximum log file size? How?

• jQuery jFlow plugin. How can I have more than one on a single page?

  - by Michael

  Hi, I'm using a very lovely and simple plugin called jFlow that gives me a basic content slider etc. However, I can see no documentation or help on how to get two (or more) on one page at the same time working seperately from one another. At the moment, if I set two up, they almost combine as one, despite having a different configuration from one another. Any help would be great, thanks. Michael.

  - by Artyom

  Hello, I'm using pthreads-win32 for portable threading support for windows. At least, according to the documentation pthreads-win32 should work with MSVC and even MSVC builds provided.
