Why does active_record break the behavior of Ruby's trap and how do I work around it?

In the last couple of days, I've been trying to get a solution to an active_record issue that has been plaguing me. Posts on railsforum and stackoverflow have turned up completely dry.

Programming a Steganography application in C/C++

I have been reading up on on steno for a while. I have seen tools that help aid in embedding messages in .mp3's and png's etc. I am familiar that they do this by replacing the least important bit. In images, these LIB are colors that the human eye can't see; thus not needed. In audio files frequencies not audible to the human ear; also n...

How is Win32 event-driven programming implemented under the hood?

In a Win32 C++ application, we start a message loop that fetches messages from a queue, translates them and then dispatches them. Eventually, each message reaches our WndProc where the associated event can be handled. I understand that part. What I don't understand is the in between goings-on. Specifically: Different kinds of OS inter...

Raw Ethernet Frames Using Winsock

I am porting a communications library from Linux to Windows. I know what my approach is for the most part. The library uses all raw ethernet level frames for all the communications. The library I am porting from makes use of the PF_PACKET family and the struct sockaddr_ll. After browsing through the MSDN winsock site, I haven't fou...
