• Pseudo LRU tree algorithm.

  - by patros

  A lot of descriptions of Pseudo LRU algorithms involve using a binary search tree, and setting flags to "point away" from the node you're searching for every time you access the tree. This leads to a reasonable approximation of LRU. However, it seems from the descriptions that all of the nodes deemed LRU would be leaf nodes. Is there a pseudo-LRU algorithm that deals with a static tree that will still perform reasonably well, while determining that non-leaf nodes are suitable LRU candidates?

• In LINQPad can you access SYSOBJECTS using LINQ?

  - by Xanthalas

  In LINQPad is there any way to access either the SYSOBJECTS table or the various INFORMATION_SCHEMA.xxx views using LINQ? I spend a lot of time searching through our huge company database for partial names as there are too many tables and Stored Procedures to remember the names of them all. I know I can enter and run SQL in LINQPad but I would like to do this in LINQ instead of SQL as LINQ is more fun :) Thanks Xanthalas

• GDI handles in a DotNET application

  - by David Rutten

  My pure DotNET library runs as a plugin inside an unmanaged desktop application. I've been getting a steady (though low) stream of crash reports that seem to indicate a problem with GDI handles (fonts in error messages etc. revert to the system font, display of all sorts of controls break down, massive crash shortly after). My Forms have few controls, but I do a lot of GDI+ drawing in User controls. What's a good way to tell how many handles I'm using, or even leaking? Thanks, David
