• Invalidating the HTTP Cache on read only front servers

  - by Microserf

  We have a CMS system and in the production mode a number of servers only have read-only access to the content (with a few exceptions) and the editors for the site work on the content on servers behind it (which are not available to the public). We're caching the content quite a long time on the front servers, but sometimes we want the content the editors publish to be available for visitors instantly. What would the best way be to invalidate the cache in this situation, should we trigger it from our code?

• CodePage ID to CodaPage name: GetEncoding equivalent in Delphi?

  - by Steve

  Hello all, I'm looking for a Win32 equivalent of the .Net Encoding.GetEncoding Method to be used in Delphi7. What I would like to achieve is to convert a Codepage ID (ie.: 28592) to a Codapage name (iso-8859-2 in this case). I've found a Win32 function called GetCPInfoEx, but that returns a long CodePage name, and I need the short one, like the ones listed on this page: (see Name column) http://msdn.microsoft.com/en-us/library/system.text.encoding.aspx Thank you!

• Why is changing displays slow?

  - by Josh Bronson

  I've had many laptops over the course of many years, and while many things have sped up, one thing remains as slow today as it was years ago: (dis)connecting an external display.
