2.9 段寄存器 我们前面讲到. 8086CPU 在访问内存时要由相关部件提供内存单元的段地址和偏移地 址，送入地址加法器合成物理地址。 这里，我们要看一下，是什么部件提供段地址。 段地 址在 8086CPU 的段寄存器中存放。 8086CPU 有 4 个段寄存器: CS , DS , SS 、 ES。当 8086CPU 要访问内存时由这 4 个段寄存器提供内存单元的段地址。 我们本课中只介绍 CS o 2.10 CS 和 IP CS 和 IP 是 8086CPU 中两个最关键的寄存器，它们指示了 CPU 当前要读取指令的地

网上其他地方基本找不到的资源——Jim Adams的《Programming Role Playing Games with DirectX》第二版的源代码，用DirectX 9.0b写成的。

经典的DX11龙书，作者依然是Frank Luna，非常值得一看

About This Book, Use Python and QGIS to create and transform data, produce appealing GIS visualizations, and build complex map layoutsLearn undocumented features of the new QGIS processing moduleA set of user-friendly recipes that can automate the entire geospatial workflows by connecting Python GIS building blocks into comprehensive processes, Who This Book Is For, If you are a geospatial analyst who wants to learn more about automating everyday GIS tasks or a programmer who is responsible for building GIS applications,this book is for you. The short, reusable recipes make concepts easy to understand. You can build larger applications that are easy to maintain when they are put together., What You Will Learn, Build a library of reusable scripts with ScriptRunner Create, import, and edit geospatial data on disk or in memory Get to know more about dynamic mapping Create and add features to static maps Create a mapbook Reproject a vector layer Geolocate photos on a map Combine multiple rasters into one image, In Detail, QGIS Python Programming will teach you how to write Python code that works with spatial data to automate geoprocessing tasks in QGIS. It will cover topics such as querying and editing vector data and using raster data. You will also learn to create, edit, and optimize a vector layer for faster queries, reproject a vector layer, reduce the number of vertices in a vector layer without losing critical data, and convert a raster to a vector. Following this, you will come across recipes that will help you to compose static maps, create heavily customized maps, and add specialized labels and annotations. Apart from this, the book will also share a few tips and tricks based on different aspects of QGIS.

This guide is ideal if you're a professional, manager, or student who wants practical knowledge of analyzing data, without having to get a PhD in statistics. It's also good for people who have a PhD in statistics, but may not know how to write programs that apply statistical methods to real data. Discover how to apply the R language to data analysis through active learning and hands-on demonstration. You'll learn how to use R libraries that useful and reliable for data analysis, and how they can save you time and stress. Learn from a PhD-level statistician who develops and leads R courses Start analyzing data with R, rather than absorb academic statistics concepts Run more powerful analyses and make better-looking graphs Spend less time coding, with ggplot2, plyr, reshape2, and lubridate Learn how to make decisions during a data analysis
