• Receiving data from a USB device in C or C++

  - by Midas

  It starts to bore me that I always have to ask questions about trifles. I simply need a list of all plugged in USB devices and have the user select one to let the console application receive any data the USB device sends. I can then start playing around with the data in my program. I don't want to use library's, only standard C++ functions, and the program should work in Windows 98.

• Establish SSH Connection Between Two Isolated Machines Using a 3rd System

  - by FurryHead

  I'd like to do the following with Python: Computer 1 starts SSH server (probably using twisted or paramiko) Computer 1 connects to Server 1 (idle connection) Computer 2 connects to Server 1 Server 1 forwards Computer 2's connection to Computer 1 (connection no longer idle) Computer 1 forwards Server 1's connection to listening SSH port (on computer 1) Result being Computer 2 now has a SSH session with Computer 1, almost as if Computer 2 had started a normal SSH session (but with Server 1's IP instead of Computer 1's) I need this because I can't port forward on Computer 1's network (the router doesn't support it).

I would like to make a word-based diff between them (like whe unix utility wdiff does) but with more information in the output (I mean, the character's posizion where the added/delited word starts).
