It’s my great honor and the, I was invited about months ago. I did not expect,people said this is very sensitive time for me to talk,because about yahoo ,about alibaba about this ,that, so I promise promise,I come,T oday any question you have,I will answer any question you have.All right,so I‟ve been here for fifteen day and I planed to spend one year here. Nobody know,my company did not know that,I am gonna spend one year here. Cause people asked why you are here?Are you here for getting yahoo? “NO”Everybody was very sensitive when I said “,I am gonna spend one year here” ,and the I just come here I am tired ,too tired in the past sixteen year,I start my business ,when I started 1994 internet ,I got crazy about the internet,,gave up my job in the teaching, I called myself like blind man riding on the back of a blind tiger, jumping around,and still KIKI ,still surviving,and then join the govement organization for sixteen months, not successful ,started alibaba 1999. and we built up the alibaba,we are luck enough,we have the taobao ,we have the alipay we have ali cloud computing,and the so many things,after 12years,I say:”I need some time to rest” , especially,this year,so difficult for me , I did not expect. Per 12 years was china call the “本命年“. This is our 12 year for alibaba.At the beginning of the year,,we have the,you know ,moving for alibaba b2b CEO,because the customer cheating thing,and then we have the alipay about the VIE.I still don‟t know what the VIE is,”right”, and then we have the ,taobao separate into 4 parts,so many things ,It really make me fell tired,and I said:”well, why not give up 1 year ,because next year is my personal “本命年”,which could be much more difficult ,so this year is very tough and difficult,,I believe,next year,it‟s gonna be tough ,more difficult, more “听不清“,So I got ready for that, and I need think,need rest,so in order to for any another 3,,4year hard work,because this 3year,it‟s not my job,if something wrong,criticize the president of taobao,CEO of the alibaba and alicloud,it‟s their fault,3 year later ,something wrong,my fault.so I come here and I will spend most of time in United States,and then thingking relaxing.2 days ago,I picked up my golf,just relax ,nothing about ,the things people think about. So we are very luck company,and there is no chance that we survive, I don‟t have any sort of the background ,richfather,strong uncle, and the,I remember 1999,I came to Silicon Valley ,loking for venture capital. I talked to lots of venture capital,and I remember a few days ,I drop by Menlo park,I was rejected by so many venture capital, when talked about alibaba startup,they looked at the stranger,”what” ,”what are you talking about?I went back to china,with nothing,no money, nobody invested me,but I‟m full of confident,I saw America dream.At that time ,1999,I walked on the high “没听清”,every evening full of cars in the park of company,Sunday full of car,people work day and night,This is something ,I believe it‟s gonna happen in china,without getting any venture capital,but I think ,I went back china with America dream and we started the business there,and after 12 years,you know, a lot of things happen,we built up the B2B,nobody believed the B2B will work ,because the B2B at that time with aliba ,I don‟t know still there. “ariba .com”,”broadvision”,”commerce one”this is very famous B2B company. People said :”how can you do B2B in china. Because B2B in USA focus on big company ,they focus on buyer,and we believe that three is no big company in china,and I don‟t see, in the short term, china will have lots of big company,because big company is only SOE,SOE ,they do not the ecommerce, they need govement policy.so we focus on small business,we believe china,the small business ,the private sector are the future.so wefocus on that, and the B2B in usa ,they focus. They want to help the buyer save the cost ,save the time.we believe:”don‟t don‟t teach the SME,don‟t teach the small business how to save the cost.because know much better than you do. You shound help them how to make money.so we focus on helping small business,we focus on helping them make money ,sell things abroad.Very difficult to do business,at that time,but after 12 years,we got more than 58 millions small business around the world using our service.that model is not very successful,compare to “tencent “”baidu”,.we did not make that much money,like online gaming,but we can sleep well in the evening, because the money we made not online gaming, the money we made is helping small business survive, get business opportunity which I fell very proud of that, and today ,as always,I never fell proud of how much money we made,I fell proud of how much impact we can help others,especially small business,before the history of internet,no company can help over 50 millions SME,today we are trying.andf I fell proud of that this is the first company,and people said :”jack,if you make alibaba successful,that means :”you are pulling a million ton sheep on the top of the Himalayas and I said :”yes,we will carry that thing down” and we did. The second company call taobao ,and everybody said :”oh my god ,you are competing with ebay. I said :”why not,”, china need ecommerce site and building up china market take effort ,take time and take great “没听清“really want to build up something, so at that time people said :”there is no chance “ well !, if you never try ,how do you know that there is no chance. So we try . And I said :” if ebay is the sharp in the ocean, we are crocodile in the yangzi river. Never fight in the ocean, let‟s fight in the Yangzi river. it was difficult, it was lots of fun,and we survive . they got 90%market share at that time, today for C2C,we own 90%market share. And luck ,just luck,thre are lots of can be disscuss in the future. Today ,people always write about the successful story about alibaba. And I really don‟t think we are so smart.we made so many mistake.we were so stupid at that time.so I think someday the book I personnally really want to write about is alibaba 1001 mistakes. That‟s the things people should remember ,should learn. If you want to learn “how the other people succeed,it‟svery difficult.thre arelots of luck things at there. But if you want to learn “ how people fail “,you will benefit a lot,and I always like to read those book talking about “how people fail”,because,if you look into it any company theiy fail,the reason why they fail almost the same,and that really matters, so taobao succeed,and then we have the alipay,because everybody said:”china oh ,no credit system, banking is terrible, logistics is terrible. How can you do ecommerce .I never tell, just like today I come here without PPT without my business,I not come here sell you business ,sell my business. Because I don‟t stock to sell to you guys. But I think because china is not good at logistics,not good at credit system,not goog at banking system, that‟s why we need entrepreneurship, that‟s why we go ,we should go, build them up. So I believe ,if there is no, you build it up,later that‟s become the standard of china and I believe china need that.I remember ,6 years ago,I came to the states,I told the USA audience. I believe 5 years later, china will have more internet users than USA. people said “No” , I said :”well ,you have 300 millions population,china 1.3 billions ,right! If you guys have 400 millions internet users,without any people die, keep on having baby ,, it take 50 years , we need 5 years. it‟s just time issue, right !. let‟s wait and see, today we have more users ,today people say :”why your buy capability is low, let‟s see about 5 years later. 5 year later,today,peopleonly spend 200 RMB per month,5 years later,this guy will spend 2000. and we have patients, we are young,you know, my people only 26 average age, they are young. let‟s wait for the future. So ,alipay,was just like very ,at that time people said :”it‟s stupid “没听清“service. John wants to buy things from Stevens, John just not want to “没听清”the money . Stevens don‟t want to send the poducts. So we open account, “没听清“,ifyou happy ,” “没听清“the money ,not happy,return poduct,return money. People said :” how stupid the model is”, well! We don‟t care whether stupid or not stupid. we care whether the customer wanted or not,whether really meet the need of customer,, if it‟s stupid, but after 7years ,we have more than 600 millions users, registered users in china using that. So stupid thing , if you improve it every day,it …s gonna be very smart. And we believe that,and today , it …s good ,and it‟s growing, just like paypal,we are bigger than paypal right now , on transaction volume. And the last , most important is alicloud computing,and not like the other company ,they talk about cloud computing,they want to sell you the,hardware, software. We have nothing to sell you .we just want to compute our own datas. Because the datas we have from the SME,because the datas we have from consumer of taobao,datas from alipay. We believe in the future the world is going to data process in the world. How can we share the datas with others in a great way. Right! That‟s the business about, it‟s not that good yet, but it‟s very profitable,the whole com pany look health,we are very appreciate, we are the company from “没听清“,there is no chances we can win ,now we survive. I think we always ask our own question:” why we are still working so hard. I talked to my colleague one day ,and he said :” I never know that in my life, I can do that much”, second” I never know that the thing I doing that meaningful to the society, third ,I never know that life is that “没听清”hard。

To support this we have structured this guide in-line with the final assessment; giving your students the opportunity explore ideas and develop an understanding of the content, to practice and refine their skills, and gain an understanding of the depth and breadth that will be required in their final assessment. The project consists of five tasks covering a wide range of the standards. Each task includes several activities that students can carry out individually or in groups. If working within a group, we would advise that students contribute to each of the tasks, in order to gain the experience and skills required for the external assessment. The activities are designed to help teach the skills required within each of the tasks and give the opportunity for students to practice before their final assessment.The intention is that the students will be taught a range of knowledge and skills within each of the units and then carry out a series of tasks, linked to a scenario. Completion of each of the tasks successfully will demonstrate understanding and competency of the identified standards._____________________________________________________________________________________Make-up of the guideThe first section of the guide goes through the scenario and provides details of the company that will form the context of the project.Following this is a pack of teaching and learning activities, structured as 5 tasks, for all the content that needs to be taught, as well as activities to reinforce learning for the scenario.ScenarioYour friend is turning 40 next year and a group of you want to celebrate the special occasion by going on a 2-week holiday.

以下为马云在斯坦福大学演讲全文:马云:大家好.我今天感到非常荣幸能来到这里和大家见面。

大约几个月前,斯坦福邀请我来演讲。

我没有意料到。

很多人说因为所有关于雅虎,阿里巴巴,和许多其他的新闻,这个时间点来这里演讲是非常的敏感。

但是既然我做了一个承诺,我还是来了。

今天如果你有任何问题要问我,我都会一一回答。

The following is the Ma at Stanford University speech:Ma : Hello everyone 。

Today I feel very honored to be here to meet you 。

About a few months ago ,Stanford invited me to lecture . I did not expect . Many people say that because of all about Yahoo ,Alibaba,and many other news,this time to speak here is very sensitive . But since I made a promise that I came。

Today, if you have any questions to ask me, I will be to answer every qestions。

今天是我来美国的第15天,而且我打算在这里待上一年。

这个计划没有人知道。

甚至我的公司也不知道。

大家问我为什么要来这里.要打算作收购雅虎的准备吗?不,大家都太敏感了.我来这里是因为我累了.过去16年来太累了。

我在1994年开创我的事业,发现了互联网,并为之疯狂,然后放弃了我的教师工作。

那时候我觉得自己就像是蒙了眼睛骑在盲虎背上似的,一路摔摔打打,但依然奋斗着、生存着。

在政府机关工作了16个月之后,1999年建立了阿里巴巴.I came to the United States today is the first 15 days ,and I intend to stay here for a year . No one knows this plan 。

• All of Rn . It should be fairly obvious that given any x, y ∈ Rn , θx + (1 − θ)y ∈ Rn . • The non-negative orthant, Rn + . The non-negative orthant consists of all vectors in n R whose elements are all non-negative: Rn + = {x : xi ≥ 0 ∀i = 1, . . . , n}. To show that this is a convex set, simply note that given any x, y ∈ Rn + and 0 ≤ θ ≤ 1, (θx + (1 − θ)y )i = θxi + (1 − θ)yi ≥ 0 ∀i. • Norm balls. Let · be some norm on Rn (e.g., the Euclidean norm, x 2 = n n 2 i=1 xi ). Then the set {x : x ≤ 1} is a convex set. To see this, suppose x, y ∈ R , with x ≤ 1, y ≤ 1, and 0 ≤ θ ≤ 1. Then θx + (1 − θ)y ≤ θx + (1 − θ)y = θ x + (1 − θ) y ≤ 1 where we used the triangle inequality and the positive homogeneity of norms. • Affine subspaces and polyhedra. Given a matrix A ∈ Rm×n and a vector b ∈ Rm , an affine subspace is the set {x ∈ Rn : Ax = b} (note that this could possibly be empty if b is not in the range of A). Similarly, a polyhedron is the (again, possibly empty) set {x ∈ Rn : Ax b}, where ‘ ’ here denotes componentwise inequality (i.e., all the entries of Ax are less than or equal to their corresponding element in b).1 To prove this, first consider x, y ∈ Rn such that Ax = Ay = b. Then for 0 ≤ θ ≤ 1, A(θx + (1 − θ)y ) = θAx + (1 − θ)Ay = θb + (1 − θ)b = b. Similarly, for x, y ∈ Rn that satisfy Ax ≤ b and Ay ≤ b and 0 ≤ θ ≤ 1, A(θx + (1 − θ)y ) = θAx + (1 − θ)Ay ≤ θb + (1 − θ)b = b.

ACM 1-xxxxxxxxxxxxxxxxxx. Dreaming of Adaptive Interface Agents

Copyright is held by the author/owner(s). CHI 2007, April 28 – May 3, 2007, San Jose, USA ACM 1-xxxxxxxxxxxxxxxxxx.
Abstract This interactive project uses the metaphor of human sleep and dreaming to present a novel paradigm that helps address problems in adaptive user interface design. Two significant problems in adaptive interfaces are: interfaces that adapt when a user does not want them to do so, and interfaces where it is hard to understand how it changed during the process of adaptation. In the project described here, the system only adapts when the user allows it to go to sleep long enough to have a dream. In addition, the dream itself is a visualization of the transformation of the interface, so that a person may see what changes have occurred. This project presents an interim stage of this system, in which an autonomous agent collects knowledge about its environment, falls asleep, has dreams, and reconfigures its internal representation of the world while it dreams. People may alter the agent’s environment, may prevent it from sleeping by making noise into a microphone, and may observe the dream process that ensues when it is allowed to fall asleep. By drawing on the universal human experience of sleep and dreaming, this project seeks to make adaptive interfaces more effective and comprehensible.

Lecture 1: Colonial AmericaI. Historical Background:The earliest settlers included Dutch, Swedes, Germans, French, Spaniards, Italians, and Portuguese.The first permanent English settlement in North America was established at Jamestown, Virginia in 1617.The war for Independence(1776-1783)The colonies, most of which in old English tradition, made the original United StatesII. American Puritanism:1. Origin of "Puritanism":The term "Puritan" first began as a taunt or insult applied by traditional Anglicans to those who criticized or wished to "purify" the Church of England. Although the word is often applied loosely, "Puritan" refers to two distinct groups: "separating" Puritans, such as the Plymouth colonists, who believed that the Church of England was corrupt and that true Christians must separate themselves from it; and non-separating Puritans, such as the colonists who settled the Massachusetts Bay Colony, who believed in reform but not separation. Most Massachusetts colonists were nonseparating Puritans who wished to reform the established church, largely Congregationalists who believed in forming churches through voluntary compacts. The idea of compacts or covenants was central to the Puritans' conception of social, political, and religious organizations. (from /faculty/campbell/enl310/purdef.htm)2. A definition of American PuritanismPuritanism is the practices and beliefs of the Puritans.The Puritans were originally members of a division of the Protestant Church, who came into existence in the reigns of Queen Elizabeth and King James !. The first settlers who became the founding fathers of the American nation were quite a few of them Puritans. They came to America out of various reasons, but it should be remembered that they were a group of serious, religious people, advocating highly religious and moral principles.As the word itself hints, Puritans wanted to purify their religious beliefs and practices. They felt that the Church of England was too close to the Church of Rome in the doctrine form of worship, and organization of authority.The American Puritans, like their brothers back in England, were idealists, believing that the church should be restored to complete …purity‟.They accepted the doctrine of predestination, original sin and total depravity, and limited atonement through a special infusion of grace from God. But in the grim struggle for survival that followed immediately after their arrival in America, they became more and more practical, as indeed they had to be. Puritans‟ lives were extremely disciplined and hard. They dro ve out of their settlements all those opinions that seemed dangerous to them, and history has criticized their actions. Yet in the persecution of what they considered error, the Puritans were no worse than many other movements in history. As a culture heritage,Puritanism did have a profound influence on the early American mind. American Puritanism also had an enduring influence on American literature. It had become, to some extent, somuch a state of mind, so much a part of the national cultural atmosphere, rather than a set of tenets.3. 21st Century PuritanismA "21st Century Puritanism", then, is the always-reforming spirit of 17th-century Puritanism applied to the challenges of the 21st century church. In place of an Arminian "free-will" gospel that exalts human worth and ability, the 21st Century Puritan calls us back to the Biblical gospel that exalts the power and sovereignty of Almighty God. In place of the "seeker-sensitive", man-pleasing paradigm for worship, the 21st Century Puritan points us back to the Biblical, God-ordained pattern of worship revealed in Scripture—emphasizing a Godward focus—preaching His glories, rejoicing in His mercy to hell-deserving sinners, falling at His feet in humble supplication, singing from joyful, forgiven, God-saturated hearts psalms and hymns that exalt His majesty and honor.(for further information, please go to /puritan)III. Puritan PoetsAnne Bradstreet (the ninth muse):"CONTEMPLATIONS" comprises thirty-three stanzas rhyming ababccc, in which six iambic pentameter lines culminate with an alexandrine. Adopting the models of Fletcher and Quarles (Stanford 101), Bradstreet, with her three "c" rhymes and closing alexandrine, modifies the nine-line stanza of The Faerie Queene; this formal kinship with Spenser is compounded by the pace of her narrative. The work was probably completed in the 1660s.First appearing in the posthumous Several Poems, "Contemplations" belongs to a later group of writings, often domestic in their subject matter, in which Bradstreet's personal voice achieves its graceful maturity.(For further information, please go to: /~mseifert/bradstreet.html)2. Edward Taylor: "Huswifery" (Chang, p19)IV. Representatives of Dawning NationalismPhilip Freneau: "The Wild Honey Suckle" (Chang, p23),"The Indian Burying Ground" Benjamin FranklinLecture 2-4: American RomanticismI. Historical Background:American pioneers had pushed the frontier line of settlement beyond the Mississippi to the west, which has risen as a sectional power to challenge the political dominance of the East and the South.Before 1860, the United States had begun to change into an industrial and urban society. Literary characteristics: Romanticism, TranscendentalismThe rise of NationalismII. American RomanticismThe Romantic Period in the history of American literature stretches from the end of the 18thcentury to the outbreak of the Civil War, which started with the publication of Washington Irving's The Sketch Book and ended with Whitman's Leaves of Grass.In this period, a new emphasis was placed upon the imaginative and emotional qualities of literature, a liking for the picturesque, the exotic, the sensuous, the sensational, the supernatural and remote past was fostered, and an increasing attention to the psychic states of their characters was paid, and above all, the individual and the common man was exalted. Dr. F. H. Hedge, an American transcendentalist, thought the essence of romanticism was aspiration, having its origin in wonder and mystery.Among the aspects of the "romantic" movement in England may be listed as a) sensibility; b) primitivism; c) love of nature; d) sympathetic interest in the past, especially the medieval; e) mysticism; and f) individualism.III. Two Earlier WritersWashington IrvingJames Fenimore CooperIV. American TranscendentalismThe most clearly defined literary thought in this period is New England Transcendentalism. 1. The definition of TranscendentalismTranscendentalism has been defined philosophically as "the recognition in man of the capacity of knowing truth intuitively, or of attaining knowledge transcending the reach of the senses."Principal ideas of Transcendentalism are based on doctrines of ancient and modern European philosophers, particularly Kant. It was started by a group of members of the Transcendental Club in New England in the 1830s, whose leaders were Emerson, who was greatly influenced by Carlyle, Coleridge and others, and his young friend Thoreau.The major concepts include:it stresses the power of intuition.2. it places spirit first and matter second.3. it takes nature as symbolic of spirit or God.(认为自然是上帝之灵的显现,说自然就是披着睡衣的:超灵(over-soul),对人的心灵有更新和康健卫生作用。

一、6 台设备组网给你 6 台路由器,核心 2 个,汇聚 2 个,接入 2 个,构思两种拓扑,你怎么规划?有什么区别?给你 6 台路由器, 2 台高性能, 2 台中等性能, 2 台低性能,构思两种拓扑,你怎么规划?有什么区别?<1>第一种拓扑:日字形拓扑上面两台作为互联网汇聚使用,分别向下面注入缺省路由,缺省路由的度量值可以不同,以供内部网络选择合适的出口。

中间两台作为核心使用,上面连接园区网汇聚路由器,下面连接园区网汇聚路由器。

在核心路由器上还可以连接其他地域的专线汇聚路由器。

下面两台作为网络网汇聚路由器,为区域网不同网络作为网关使用。

这种网络拓扑设计结构简单,端口密度要求低,容易管理,具有网络冗余。

<2>第二种拓扑:在日字形拓扑的基础上交叉互联。

六台路由器的功能和日字形拓扑相似。

这种网络拓扑设计结构复杂,端口密度要求高,不容易管理,成本略高,冗余性更好。

1. 这种拓扑(交叉型),接入部分采用双上联,核心和汇聚设备之间全互联。

这种方式接入部分双上联保证冗余,进一步保证核心和汇聚之间全互联保证拓扑冗余性,和数据逻辑走向的灵活性。

2. 第 2 种拓扑(日字型),主要采用环形,核心部分如果设备有多台,可以采用环形或者使用全互联, 这种设计在保证冗余的前提下,可以减少线路和接口成本。

可以从如下几个方面考虑A、冗余性物理层面分为设备冗余和链路冗余,日字型和交叉型都满足设备和链路冗余;交叉型较日字型冗余性更高。

两种拓扑都有冗余能力,都不存在单点故障。

B、成本开销从设备角度考虑:使用交叉型连接,会需要更多的端口、板卡,插槽,光模块,需要增加采购成本。

从线路角度考虑:若节点和节点之间距离较远,在不同的城市中,租用运营商长途专线互联,口字型一般情况下,可以满足互联互通的需求,也提供基本的冗余能力,但要追求更高的冗余性则可以使用交叉型。

租用运营商的单条线路都是按月收取费用,一般价格比较昂贵,带宽越大费用越高,所以租用成本有可能高于设备采购成本。

哈佛大学 vs 斯坦福大学

哈佛大学 vs 斯坦福大学

哈佛大学vs 斯坦福大学哈佛大学和斯坦福大学的商学院是全世界最好的两个商学院,这绝非夸张,收到哈佛或者斯坦福MBA的录取信,更是一个人被视为最高的荣誉。

也正因此,大多申请者在申请哈佛大学时,必然不会落下斯坦福大学。

而对于两个学校来说,拒绝了橄榄枝的申请者们也大都是因为选择了彼此对方。

然而即便如此,在两个学校的商学院,尤其是MBA教育之间,仍然存在着一些差别,值得申请者们在选择前进行分析。

【地理位置】地理位置是两个学校间最明显,也很重要的一点区别。

斯坦福坐落于硅谷中心,整个校园里是到处可见的棕榈树。

在冬季,当哈佛的学生们裹得严严实实在冰雪中穿梭时,斯坦福的学生们则可能仍然穿着短衣短裤。

斯坦福位于San Jones和San Francisco之间,二者大约有45分钟的车程。

而哈佛,众所周知位于波士顿,学校距离波士顿棒球红袜队的“老家”芬威球场也只有数分钟的路程而已。

但哈佛的冬天对于任何人来讲都是难熬的——这是哈佛和斯坦福间不能忽视的重大差别。

【MBA规模】斯坦福的MBA较小,不到哈佛的一半——哈佛是世界MBA人数最多的大学。

每一届390人,能够保证学生间彼此的相互认识。

斯坦福full-time MBA的总数是765,哈佛的则有1837,由此两个学校规模上的差别可见一斑。

【设备设施】斯坦福商学院的规模是小而紧凑的,只有4座楼(还包括了住宿楼),MBA们要在一座1966年建造的教学楼中上课。

相反,哈佛商学院则拥有属于自己的33座独立建筑,其中有独立的健身中心和壮观辉煌的图书馆,甚至还有一个小教堂。

世界上没有任何一所商学院能和哈佛商学院在教室数量和建筑规模上相媲美。

斯坦福商学院的校园现状也将有所改善,他们将在2011年搬入新的校园——由斯坦福校友Nike创始人Phil Knight部分捐赠建成,新的校园将拥有9个世界一流的建筑设施。

【校园文化】当哈佛将其essay的题目公开——要求写出“your three most substantial accomplishments”时,我们就没有理由不去相信“成就”二字之于哈佛的重要性。

Comparing NULL’s to Values
The logic of conditions in SQL is really 3valued logic: TRUE, FALSE, UNKNOWN. Comparing any value (including NULL itself) with NULL yields UNKNOWN. A tuple is in a query answer iff the WHERE clause is TRUE (not FALSE or UNKNOWN).
