These routines transmit and receive serial data using two general
* I/O pins, in 8 bit, No parity, 1 stop bit format. They are useful
* for performing serial I/O on 8051 derivatives not having an
* internal UART, or for implementing a second serial channel.

Decoding most of the infrared signals can be easily
handled by PIC16C5X microcontrollers. This application
note describes how this decoding may be done.
The only mandatory hardware for decoding IR signals
is an infrared receiver. The use of two types is
described here. Both are modular types used often by
the consumer electronics industry. The first type
responds to infrared signals modulated at about
40 kHz. The second responds to non-modulated infrared
pulses and has a restricted range. The hardware
costs of each approach will be less than two dollars.

MFC Black Book
Introduction:
Are you an MFC programmer? Good. There are two types of MFC programmers. What kind are you? The first kind are the good programmers who write programs that conform to the way MFC wants you to do things. The second bunch are wild-eyed anarchists who insist on getting things done their way. Me, I’m in the second group. If you are in the same boat (or would like to be) this book is for you.
This book won’t teach you MFC—not in the traditional sense. You should pick it up with a good understanding of basic MFC programming and a desire to do things differently. This isn’t a Scribble tutorial (although I will review some fundamentals in the first chapter). You will learn how to wring every drop from your MFC programs. You’ll discover how to use, abuse, and abandon the document/view architecture. If you’ve ever wanted custom archives, you’ll find that, too.

The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d .
Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet.
Create a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1.

The Linux kernel is one of the most interesting yet least understood open-source projects. It is also a basis for developing new kernel code. That is why Sams is excited to bring you the latest Linux kernel development information from a Novell insider in the second edition of Linux Kernel Development. This authoritative, practical guide will help you better understand the Linux kernel through updated coverage of all the major subsystems, new features associated with Linux 2.6 kernel and insider information on not-yet-released developments. You ll be able to take an in-depth look at Linux kernel from both a theoretical and an applied perspective as you cover a wide range of topics, including algorithms, system call interface, paging strategies and kernel synchronization. Get the top information right from the source in Linux Kernel Development.

Title: STL Tutorial and Reference Guide: C++ Programming with the Standard Template Library (2nd Edition)
Author: David R. Musser / Gillmer J. Derge / Atul Saini / Gilmer J. Derge
Publisher: Addison-Wesley
Page: 560
Edition: 2nd edition (March 27, 2001)
Format: PDF
Summary: The Standard Template Library was created as the first library of genetic algorithms and data structures, with four ideas in mind: generic programming, abstractness without loss of efficiency, the Von Neumann computation model, and value semantics. This guide provides a tutorial, a description of each element of the library, and sample applications. The expanded second edition includes new code examples and demonstrations of the use of STL in real-world C++ software development it reflects changes made to STL for the final ANSI/ISO C++ language standard.
