內容簡介“舊時王謝堂前燕，飛入尋常百姓家”，在研究圖形化編程時就有這種感覺，原來屬于程序員們玩的編程，通過 scratch 圖形化編程工具讓普通人經過幾個小時學習也能玩，每個人都可以通過它發揮自己的想象力，用編程的方式去表達自己的內心。這個過程就如同當年的 DOS 向 Windows 轉變，正是這種圖形化操作窗口的出現，讓普通人在電腦面前不再恐懼，電腦做為表達自己的一種工具逐漸開始普及。本書系統闡述了 scratch 圖形化編程軟件的一個開發版本 scratch for pcDuino 的初步應用。使讀者能夠初步了解用程序解決問題的一般步驟和方法。本書在編寫形式上以主題引領任務，以任務驅動應用，以應用帶動能力，使讀者在使用時可操作性強。本書結合本地化素材，通過“游戲介紹”、“準備道具”、“腳本設計”、“游戲拓展”以講故事的方式，啟發讀者在探究的過程中完成學習任務。這種編排也有利于使用本書進行教學的教師，可以在此基礎上建立自己的本地化教材。

The LogiCORE™ GTP Wizard automates the task of creating HDL wrappers to configure the high-speed serial GTP transceivers in Virtex™-5 LXT and SXT devices. The menu-driven interface allows one or more GTP transceivers to be configured using pre-definedtemplates for popular industry standards, or from scratch, to support a wide variety of custom protocols.The Wizard produces a wrapper, an example design, and a testbench for rapid integration and verification of the serial interface with your custom function Features• Creates customized HDL wrappers to configureVirtex-5 RocketIO™ GTP transceivers• Users can configure Virtex-5 GTP transceivers toconform to industry standard protocols usingpredefined templates, or tailor the templates forcustom protocols• Included protocol templates provide support for thefollowing specifications: Aurora, CPRI, FibreChannel 1x, Gigabit Ethernet, HD-SDI, OBSAI,OC3, OC12, OC48, PCI Express® (PCIe®), SATA,SATA II, and XAUI• Automatically configures analog settings• Each custom wrapper includes example design, testbench; and both implementation and simulation scripts

SDP Search and Record generator OVERVIEW: Recognizing the difficulty in creating an SDP service description and search from scratch, Microsoft is providing a sample utility in bthnscreate.cxx to automatically create a service or record. This utility can be run to create an SDP record or to setup an SDP Service, Attribute, or ServiceAttribute search based on information stored in a human readable file.

As of UnZip 5.42, this source has been removed from Info-ZIP s UnZip source distribution because of its conflicting copyright. There are no plans to ever rewrite this code from scratch, because the unreduce algorithm was never used in the "real" world.

In this paper, we describe the development of a rapidly reconfigurable system in which the users’ tacit knowledge and requirements are elicited via a process of Interactive Evolution, finding the image processing parameters to achieve the required goals without any need for specialised knowledge of the machine vision system. We show that the resulting segmentation can be quickly and easily evolved from scratch, and achieves detection rates comparable to those of a hand-tuned system on a hot-rolled steel defect recognition problem.
