I wish this site had been around when I was trying to figure out how to make serial communications work in Windows95. I, like many programmers, was hit with the double-whammy of having to learn Windows programming and Win95 serial comm programming at the same time. I found both tasks confusing at best. It was particularly frustrating because I had, over the years, written so much stuff (including lots of serial comm software) for the DOS environment and numerous embedded applications. Interrupt driven serial comm, DMA transfer serial comm, TSR serial comm, C, assembler, various processors... you name it, it had written it. Yet, everything I knew seemed upside-down in the message-driven-callback world of Windows.
This book is about using Python to get jobs done on Windows.This intended to be a practical book focused on tasks. It doesn t aim to teach Python programming, although we do provide a brief tutorial. Instead, it aims to cover:How Python works on Windows The key integration technologies supported by Python on Windows, such as the Win32 extensions, which let you call the Windows API, and the support for COM Examples in many topic areas showing what Python can do and how to put it to work.

This book, the Sun™ ONE Message Queue (MQ) 3.0.1 Administrator’s Guide,
provides the background and information needed to perform administration tasks
for an MQ messaging system.
This preface contains the following sections:
• Audience for This Guide
• Organization of This Guide
• Conventions

The purpose of this lab is to introduce the concept of FSMs with a datapath, and to
study the usage of more complex test benches. Also, we enforce a rudimentary design
methodology by assuming that the students are part of a bigger project, and have no
knowledge of VHDL-implementation of the datapath (made by a hypothetical other
group) other than its predefined Entity Interface until they come to the lab.
The rest of this document is structured as follows: Section 2 describes some prelimi-
nary reading and exercises that should be done before the lab. Section 3 details the
design tasks that should be carried out to pass this lab.
linux filesystem bootdisk-howto.This document describes how to design and build boot/root diskettes for Linux. These disks can be used as
rescue disks or to test new system components. You should be reasonably familiar with system
administration tasks before attempting to build a bootdisk. If you just want a rescue disk to have for
emergencies,
AI::Categorizer is a framework for automatic text categorization. It consists of a collection of Perl modules that implement common categorization tasks, and a set of defined relationships among those modules
In a preemptive priority based RTOS, priority inversion
problem is among the major sources of deadline
violations. Priority inheritance protocol is one of the
approaches to reduce priority inversion. Unfortunately,
RTOS like uC/OS can’t support priority inheritance
protocol since it does not allow kernel to have multiple
tasks at the same priority. Although it has different ways
to avoid priority inversion such as priority ceiling
protocol, developers still have some difficulties in
programming real time applications with it. In this paper,
we redesign the uC/OS kernel to provide the ability to
support round robin scheduling and implement priority
inheritance semaphore on the modified kernel. As result,
we port new kernel with priority inheritance semaphore to
evaluation board, and evaluate the execution time of each
of the kernel service as well as verify the operations of
our implementation.
This application report describes the use of Timer_A3 to decode RC5 and SIRC TV IR remote control signals. The decoder described in this report is interrupt-driven and operates a background function using specific features the Timer_A3. Only a small portion of the MSP430 CPU?s nonreal-time resources is used. Specific hardware bit-latching capabilities of the Timer_A3 module are used for real-time decoding of the IR data signal, independent
and asynchronous to the CPU. CPU activity and power consumption are kept to an absolute minimum level. The Timer_A3 decoder implementation also allows other tasks to occur simultaneously if required. The solutions provided are written specifically for MSP430x11x(1) and MSP430x12x derivatives, but can be adapted to any other MSP430 incorporating Timer_A3.

Feature selection is a preprocessing technique frequently used in data mining and machine learning tasks. It can reduce dimensionality, remove irrelevant data, increase learning accuracy, and improve results comprehensibility. FCBF is a fast correlation-based filter algorithm designed for high-dimensional data and has been shown effective in removing both irrelevant features and redundant features
