Any experience with Itzam Portable Embedded Database Engine?

Has anybody ever used or have useful comments on Itzam/core? I am attracted to it partly because I was impressed by the author's book C++ Components & Algorithms and as a possible backend for my search for a large non-SQL portable database engine.

Actor model to replace the threading model?

- by prosseek

I read a chapter in a book (Seven languages in Seven Weeks by Bruce A. Tate) about Matz (Inventor of Ruby) saying that 'I would remove the thread and add actors, or some other more advanced concurrency features'. Why and how an actor model can be an advanced concurrency model that replaces the threading? What other models are the 'advanced concurrency model'?

WinForms name chooser

- by PavelR

I have a set of names (first, last, salutation) and need a control to allow users to select a single name using WinForms. A ComboBox works fine if the there are ~20 names, but not so well when there are 100 names. Can anyone recommend a name picker? Perhaps an address book control that I could customize? It's not too hard to write my own, but I have other wheels to invent.

What Sorting Algorithm Is Used By LINQ "OrderBy"?

- by Mystagogue

Evidently LINQ's "OrderBy" had originally been specified as unstable, but by the time of Orca it was specified as stable. Not all documentation has been updated accordingly - consider these links: Jon Skeet on OrderBy stability Troy Magennis on OrderBy stability But if LINQ's OrderBy is now "stable," then it means it is not using a quicksort (which is inherently unstable) even though some documentation (e.g. Troy's book) says it is. So my question is: if not quicksort, then what is the actual algorithm LINQ's orderBy is using?
