About the INFORMS Certified Analytics Professional (CAP®) Program INFORMS is pleased to continue the implementation of CAP® the professional certification program that meets the needs of analytics professionals. The Certified Analytics Professional (CAP®) program was developed in 2011–2012. The first examination was administered on April 7, 2013, at the INFORMS Analytics Conference, April 7–9, in San Antonio, Texas. INFORMS analytics certification program advances the use of analytics by setting agreed upon standards for the profession and advances the profession by providing a means for organizations to identify and develop qualified analytics professionals, by contributing to the career success and continued competence for analytics professionals, and by improving the credibility and visibility of the analytics profession. INFORMS defines analytics as the scientific process of transforming data into insight for making better decisions. Analytics is seen as an end-to-end process beginning with identifying the business problem to evaluating and drawing conclusions about the prescribed solution arrived at though the use of analytics tools and methodologies. Analytics professionals are skilled at this process. INFORMS is the first professional society to develop a professional certification program for analytics professionals. Key components of the CAP® program include the following: 1. Formal credentialing requirements, including a standardized examination and required renewal process. 2. Program content based on the findings of a job task analysis working group, whose members represent a broad background of analytics practitioners (see the section titled “About the Professional Job Task Analysis Process”). 3. Agreed-upon eligibility criteria that consist of academic preparation, work experience in analytics, and an attestation from an employer confirming adequate mastery of soft skills in analytics. 4. Certification program content that is both software and vendor neutral. 5. Successful completion of the certification process enabling analytics professionals (and their employers) to have confidence that they bring a core set of analytics skills to a project team. The CAP® examination measures acceptable performance across seven major areas or domains of practice that adhere to the analytics end-to-end process: business problem framing, analytics problem framing, data, methodology selection, model building, deployment, and model life cycle management. See the “About the Professional Job Task Analysis Process” section for more information about the end-to-end process that is covered by the exam. Because analytics is an end-to-end process, the CAP® examination assesses a breadth of knowledge across the seven domains, but not a depth of knowledge in any one methodology. Those interested in taking the CAP® examination should consider themselves to be analytics professionals or semi-professionals, and not analytics amateurs. They should be interested in adhering to the highest standards of good analytics 2 practice and following a path of continual professional development in analytics. Candidates must have at least three years of experience in analytics depending on their academic degree. See the “Eligibility Requirements” section for more information on qualifying for the CAP® examination. CAP® program development formally began in August 2011, when INFORMS established the INFORMS Certification Task Force to plan and develop this new analytics certification.

前言 过去二十年，我一直在磁盘工业中打转。包括一九八五至一九九二年与 陈希孟先生两次同事，先在高智一年，又要海门(Seagate Technology)七年， 去年底返台，又见到希孟，他在一科技，带了一批年青的小伙子，在极其 因难的环境中，日夜努力，要为中国的磁盘机工业，立椿下地。看看他们 的人手，再看看他们的成果，好是佩服。参观之后，他拿出了这本书说： “你看，我们在空间的时候，写了本书＂。我好感动，“写这种参考书， 费时，费力，发不了财，也出不了名＂。他说，“我知道，只是觉得应 该有这样一本书，没人写，所以我们就写了＂。好是爽快。 返美之后，花了两个月才念完这本，看了之后，有几个感想，第一，此书 深入浅出，中英文一起来，对我是受用，好几相以前想不通的东西，现 在清楚多了。第二，他举的例子，都是实实在在的真实例子，他多少年身 体力学的东西，都平平白白的撬了出来。第三，书的重点从设计、生产、 品质控制、市场价格，都一一交待清楚。第四，任何一种设计，有个缺 点，折衷优劣都分析得 恰到好处，大半时间，还给一个实用的数字(Rule of Thumb)以为参考。第五，硬盘机是一门日新又新的工业，过去十年，台 湾、大陆，都见过人家的生产线，一两年这后就都落伍停工了。此书一而 再，再而三的强调，此行业是逆水行舟的行业，不进则退。因此，书中提 许多目前及将来的新发展如“磁阻式磁头，(MR Head),局部响应大相似 (PRML Read Channel),都定自选性调整(Read / Write Adaptive ) 都是未来数年热 门的科技。 有了这本书，台湾硬盘机工业的发展就有一个起发点，中英文名词对 照也有了个准则。Seagate 正在大陆无锡建厂，若我去那里，这本书会跟我 去，那么它就是台湾与大陆磁盘科技交流的开始。

0、工作组名一致。 1、检查两台电脑的IP是否处在同一网段，子网掩码是否相同。 2、在“控制面板”中的“用户帐户”启用Guest帐号。 3、在开始菜单运行中输入secpol.msc启动“本地安全策略”，本地策略 -> 用户权利分配， 打开“拒绝从网络访问这台计算机”，删除guest用户。 4、打开控制面板 -> 网络和Internet连接 -> Windows防火墙 -> 例外，勾选“文件和打印机共享”。 5、是否有共享资源（共享文件夹设为共享？）。 6、本地策略 -> 安全选项，禁止"帐户：使用空白密码的本地帐户只允许进行控制台登陆"。 7、运行注册表编辑器（在运行键入“regedit”），依次打开：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa， 将键名为“restrictanonymous”的值从“1”改为“0”，即可解决蕃茄花园v2.3局域网中的访问问题 8、访问XP的时候，登录对话框中的用户名是灰的,始终是Guest用户，不能输入别的用户帐号。 解决方法：本地策略 -> 安全选项 -> "网络访问：本地帐户的共享和安全模式"，修改为"经典-本 地用户以自己的身份验证" 9、对方电脑不弹出用户名框，可进入电脑，打不开对方电脑上某用户共享文件夹。原因为本机用户名为Administrator， 将本机用户名改为其它任一用户名。 另：为Guest设密码，为在“运行”中输入：rundll32 netplwiz.dll,UsersRunDll 在“用户帐户”的“用户”选项卡下先选中Guest 用户，然后再点下面的“重设密码”，给Guest用户设个密码，顺便把上面的那个勾也打上吧。——主要争对XP家庭版。 注：有些设置要重启电脑才有效果。

What follows are three distinct parts that can be read either independently or as a connected whole. Part 1 is about the purpose and importance of having principles in general, having nothing to do with mine. Part 2 explains my most fundamental life principles that apply to everything I do. Part 3, explains my management principles as they are being lived out at Bridgewater. Since my management principles are simply my most fundamental life principles applied to management, reading Part 2 will help you to better understand Part 3, but it’s not required—you can go directly to Part 3 to see what my management principles are and how Bridgewater has been run. One day I’d like to write a Part 4 on my investment principles. If you are looking to get the most bang for your buck (i.e., understanding for the effort), I suggest that you read Parts 1 and 2, and the beginning of Part 3 (through the Summary and Table of Principles) which will give you nearly the whole picture. It’s only about 55 pages of a normal size book. Above all else, I want you to think for yourself—to decide 1) what you want, 2) what is true and 3) what to do about it. I want you to do that in a clear-headed thoughtful way, so that you get what you want. I wrote this book to help you do that. I am going to ask only two things of you—1) that you be open-minded and 2) that you honestly answer some questions about what you want, what is true and what you want to do about it. If you do these things, I believe that you will get a lot out of this book. If you can’t do these things, you should reflect on why that is, because you probably have discovered one of your greatest impediments to getting what you want out of life.

介绍硬盘的自检功能。自检功能包含三大部分： 1) an electrical segment wherein the drive tests its own electronics. The particular tests in this segment are vendor specific, but as examples: this segment might include such tests as a buffer RAM test, a read/write circuitry test, and/or a test of the read/write head elements. 2) a seek/servo segment wherein the drive tests it capability to find and servo on data tracks. The particular methodology used in this test is also vendor specific. 3) a read/verify scan segment wherein the drive performs read scanning of some portion of the disk surface. The amount and location of the surface scanned are dependent on the completion time constraint and are vendor specific.

This standard defines JEDEC requirements for solid state drives. For each defined class of solid state drive, the standard defines the conditions of use and the corresponding endurance verification requirements. Although endurance is to be rated based upon the standard conditions of use for the class,the standard also sets out requirements for possible additional use conditions as agreed to between manufacturer and purchaser.

This document defines a standard NAND flash device interface interoperability standard that provides means for a system to be designed that can support Asynchronous SDR, Synchronous DDR and Toggle DDR NAND flash devices that are interoperable between JEDEC and ONFI member implementations. This standard was jointly developed by JEDEC and the Open NAND Flash Interface Wokrgroup, hereafter referred to as ONFI
