'What Do You Really Want From Us?' 【The Washington Post】 Sunday, May 18, 2008 This poem appeared on the Internet in March and has since gone viral, popping up on thousands of blogs and Web sites, in both English and Chinese. Its authorship could not be confirmed. When we were the Sick Man of Asia, We were called the Yellow Peril. When we are billed as the next Superpower, we are called The Threat. When we closed our doors, you launched the Opium War to open our markets. When we embraced free trade, you blamed us for stealing your jobs. When we were falling apart, you marched in your troops and demanded your fair share. When we tried to put the broken pieces back together again, Free Tibet, you screamed. It was an Invasion! When we tried communism, you hated us for being communist. When we embraced capitalism, you hated us for being capitalist. When we had a billion people, you said we were destroying the planet. When we tried limiting our numbers, you said we abused human rights. When we were poor, you thought we were dogs. When we lend you cash, you blame us for your national debts. When we build our industries, you call us polluters. When we sell you goods, you blame us for global warming. When we buy oil, you call it exploitation and genocide. When you go to war for oil, you call it liberation. When we were lost in chaos, you demanded the rule of law. When we uphold law and order against violence, you call it a violation of human rights. When we were silent, you said you wanted us to have free speech. When we are silent no more, you say we are brainwashed xenophobes. Why do you hate us so much? we asked. No, you answered, we don't hate you. We don't hate you either, But do you understand us? Of course we do, you said, We have AFP, CNN and BBC. . . . What do you really want from us? Think hard first, then answer . . . Because you only get so many chances. Enough is Enough, Enough Hypocrisy for This One World. We want One World, One Dream, and Peace on Earth. This Big Blue Earth is Big Enough for all of Us. http://www.washingtonpost.com/wp-dyn/content/article/2008/05/16/AR2008051603460.html 【译文-中文】你究竟想让我们怎么样？ 【翻译作者】：mossblue This poem appeared on the Internet in March and has since gone viral, popping up on thousands of blogs and Web sites, in both English and Chinese. Its authorship could not be confirmed. 这首诗在三月时出现在互联网上，自此之后如病毒一样在英国和中国两地的上千篇博客和网站传播。这首诗的作者尚未得到确认。 When we were the Sick Man of Asia,We were called the Yellow Peril. 曾经我们是东亚病夫，我们被叫成黄祸。 When we are billed as the next Superpower, we are called The Threat. 现在我们被宣传为下一个超级大国，我们又被称作恐吓。 When we closed our doors, you launched the Opium War to open our markets. 曾经我们闭关锁国，你发动鸦片战争撞开我们的大门。 When we embraced free trade, you blamed us for stealing your jobs. 最终我们拥抱了自由贸易，而你则谴责我们抢断了你们的工作。 When we were falling apart, you marched in your troops and demanded your fair share. 曾经我们势如危卵，你调转铁蹄来强取豪夺。 When we tried to put the broken pieces back together again, Free Tibet, you screamed. It was an Invasion! 当我们想重拾旧山河，你高叫着：解放西藏，希望我们相向倒戈！ When we tried communism, you hated us for being communist. 我们走上共产主义道路，你仇视我们是布尔什维克。 When we embraced capitalism, you hated us for being capitalist. 我们和资本主义结合，你厌恶我们是资本投机者。 When we had a billion people, you said we were destroying the planet. 我们拥有数十亿人民，你说我们挤占地球。 When we tried limiting our numbers, you said we abused human rights. 我们控制人口膨胀，你控诉我们人权龌龊。 When we were poor, you thought we were dogs. 我们贫穷落魄，你认为我们是猪猡。 When we lend you cash, you blame us for your national debts. 现在你借债许多，却责骂我们是你是的债权国。 When we build our industries, you call us polluters. 我们建设自己的工业，你叫我们污染者。 When we sell you goods, you blame us for global warming. 我们销售你的商品，你给我们扣上全球变暖的黑锅。 When we buy oil, you call it exploitation and genocide. 我们购买石油，你说我们进行能源剥削导致枯竭 When you go to war for oil, you call it liberation. 你们为石油大动干戈，你美名曰拯救尔等于水火。 When we were lost in chaos, you demanded the rule of law. 当我们混乱不堪、你呼吁什么法律规则。 When we uphold law and order against violence, you call it a violation of human rights. 当我们有法可循、除暴安良，你指着这是践踏人权、罪不可赦。 When we were silent, you said you wanted us to have free speech. 当我们沉默，你说想要我们发出自由之声。 When we are silent no more, you say we are brainwashed xenophobes. 当我们不再沉默，你却将我们描绘被洗脑的仇外者。 Why do you hate us so much? we asked. 为什么你如此仇视我们？我们问到 No, you answered, we don’’t hate you. 不，你回答，我们没有仇视。 We don’’t hate you either, 我们对你亦无仇恨。 But do you understand us? 但你们可了解我们？ Of course we do, you said, 当然了解，你说道， We have AFP, CNN and BBC. . . . 我们有AFP、CNN和BBC…… What do you really want from us? 你究竟想让我们怎么样？ Think hard first, then answer . . . 好好想想吧，你们能如此一簧两舌…… Because you only get so many chances. 只因我们宽宥待人、有容乃大。 Enough is Enough, Enough Hypocrisy for This One World. 就此打住吧，我们看尽了世间假仁假义。 We want One World, One Dream, and Peace on Earth. 只求得美美与共、天下大同。 This Big Blue Earth is Big Enough for all of Us. 在这片碧顶穹空下是我们共同的家园。 http://www.tianya.cn/publicforum/content/no110/1/124576.shtml

这个事很无奈，应引起重视！属于个人信息安全问题，恶意挖掘个人信息要遏制！！！ DoNotTrack.Us is a collaboration of researchers at the Stanford Law School Center for Internet and Society and the Security Laboratory at the Stanford Department of Computer Science to explore implementation and foster pluralist discussion of Do Not Track. The principal researchers are Jonathan Mayer and Arvind Narayanan . Overview Do Not Track is a technology that enables users to opt out of third-party web tracking, including behavioral advertising. At present a user cannot opt out of many of the hundreds of tracking services and advertising networks; those that do allow opting out each require setting (and not deleting!) an opt-out cookie. Much like the popular Do Not Call registry, Do Not Track provides users with a single, persistent setting to opt out of web tracking. Here's how it works: Whenever a web browser requests content or sends data using HTTP, the protocol that underlies the web, it can optionally include extra information, called a "header." Do Not Track simply adds a header indicating the user wishes to not be tracked. Note that Do Not Track differs from the Do Not Call registry in employing a decentralized design; it thus avoids the substantial technical and privacy challenges inherent to compiling, updating, and sharing a comprehensive registry of tracking services or web users. Compliance with Do Not Track could be purely voluntary, enforced by industry self-regulation, or mandated by state or federal law. We do not take a position on these alternatives. 详细情况进网站：http://donottrack.us/

All accepted papers must be presented at the symposium by one of the authors. http://www.dcs.gla.ac.uk/conferences/gi2011/cfp.html
... or you could be stuck with a rejected manuscript that can no longer be considered by a paper journal... What does this mean for you? The Internet has greatly facilitated scientific publication. It has also made possible the creation of entirely new types of publication venues that do not conform to the traditions of the pre-Internet era peer-review system. In this brave new world all is not what it might seema reference in the format of a peer-reviewed journal may not have passed peer review; it might very well be rejected work that is published on the Internet. Similarly, authors who are considering submitting their work to a journal that publishes submissions on-line should be aware of the possible consequences. If their work is not accepted, it could end up in scientific limbo because traditional journals will very likely consider it as already published. While one intent of EGUs publication model is to ensure publication precedence for authors, in practice it can serve as a barrier to publication. You can read the whole article here: ASLO_Bullein
Journal of Medical Internet Research (JMIR) Volume 12 (2010) * Impact Factor (2008): 3.6 - Ranked top (#1/20) in the Medical Informatics and second (#2/62) in the Health Services Research category * http://www.jmir.org/2010 Content Alert, 15 Mar 2010 ==================================== ================================= UPCOMING ISSUE Volume 12, Issue 1 http://www.jmir.org/2010/1 ================================= The following article(s) has/have just been published in the UPCOMING JMIR issue (Volume 12 / Issue 1): (articles are still being added for this issue) Original Papers ------------------ Effects of Internet Use on Health and Depression: A Longitudinal Study Katie Bessire, Sarah Pressman, Sara Kiesler, Robert Kraut J Med Internet Res 2010 (Mar 12); 12(1):e6 HTML (open access): http://www.jmir.org/2010/1/e6/ PDF (members only): http://www.jmir.org/2010/1/e6/PDF Background: The rapid expansion of the Internet has increased the ease with which the public can obtain medical information. Most research on the utility of the Internet for health purposes has evaluated the quality of the information itself or examined its impact on clinical populations. Little is known about the consequences of its use by the general population. Objective: Is use of the Internet by the general population for health purposes associated with a subsequent change in psychological well-being and health? Is the effect different for healthy versus ill individuals? Does the impact of using the Internet for health purposes differ from the impact of other types of Internet use? Methods: Data come from a national US panel survey of 740 individuals conducted from 2000 to 2002. Across three surveys, respondents described their use of the Internet for different purposes, indicated whether they had any of 13 serious illnesses (or were taking care of someone with a serious illness), and reported their depression. In the initial and final surveys they also reported on their physical health. Lagged dependent variable regression analysis was used to predict changes in depression and general health reported on a later survey from frequency of different types of Internet use at an earlier period, holding constant prior depression and general health, respectively. Statistical interactions tested whether uses of the Internet predicted depression and general health differently for people who initially differed on their general health, chronic illness, and caregiver status. Results: Health-related Internet use was associated with small but reliable increases in depression (ie, increasing use of the Internet for health purposes from 3 to 5 days per week to once a day was associated with .11 standard deviations more symptoms of depression, P = .002). In contrast, using the Internet for communication with friends and family was associated with small but reliable decreases in depression (ie, increasing use of the Internet for communication with friends and family purposes from 3 to 5 days per week to once a day was associated with .07 standard deviations fewer symptoms of depression, p = .007). There were no significant effects of respondents initial health status (P = .234) or role as a caregiver (P = .911) on the association between health-related Internet use and depression. Neither type of use was associated with changes in general health (P = .705 for social uses and P = .494 for health uses). Conclusions: Using the Internet for health purposes was associated with increased depression. The increase may be due to increased rumination, unnecessary alarm, or over-attention to health problems. Additionally, those with unmeasured problems or those more prone to health anxiety may self-select online health resources. In contrast, using the Internet to communicate with friends and family was associated with declines in depression. This finding is comparable to other studies showing that social support is beneficial for well-being and lends support to the idea that the Internet is a way to strengthen and maintain social ties. ============================================ NEWS ANNOUNCEMENTS http://www.jmir.org/announcement __JMIR launches Open Peer Review__ A new feature on the JMIR website, open peer review articles (a href=http://www.jmir.org/reviewer/openReview/abstractshttp://www.jmir.org/reviewer/openReview/abstracts/a), allows JMIR users to sign themselves up as peer reviewers for specific articles currently considered by the Journal (in addition to author- and editor-selected reviewers).

However, reviews of these interventions to date have not systematically identified intervention characteristics and linked these to effectiveness. Objectives: The present review sought to capitalize on recently published coding frames for assessing use of theory and behavior change techniques to investigate which characteristics of Internet-based interventions best promote health behavior change. In addition, we wanted to develop a novel coding scheme for assessing mode of delivery in Internet-based interventions and also to link different modes to effect sizes. Methods: We conducted a computerized search of the databases indexed by ISI Web of Knowledge (including BIOSIS Previews and Medline) between 2000 and 2008. Studies were included if (1) the primary components of the intervention were delivered via the Internet, (2) participants were randomly assigned to conditions, and (3) a measure of behavior related to health was taken after the intervention. Results: We found 85 studies that satisfied the inclusion criteria, providing a total sample size of 43,236 participants. On average, interventions had a statistically small but significant effect on health-related behavior (d+ = 0.16, 95% CI 0.09-0.23). More extensive use of theory was associated with increases in effect size (P = .049), and, in particular, interventions based on the theory of planned behavior tended to have substantial effects on behavior (d+ = 0.36, 95% CI 0.15-0.56). Interventions that incorporated more behavior change techniques also tended to have larger effects compared to interventions that incorporated fewer techniques (P .001). Finally, the effectiveness of Internet-based interventions was enhanced by the use of additional methods of communicating with participants, especially the use of short message service (SMS), or text, messages. Conclusions: The review provides a framework for the development of a science of Internet-based interventions, and our findings provide a rationale for investing in more intensive theory-based interventions that incorporate multiple behavior change techniques and modes of delivery. ============================================ NEWS ANNOUNCEMENTS http://www.jmir.org/announcement __Medicine 2.0'10 in Maastricht: Mark your calendar__ In 2010, the Medicine 2.0 congress (Social Media and Web 2.0 in Health, Medicine, and Biomedical Research) will - for the first time ever - be hosted in Europe: Maastricht (The Netherlands) - centrally located in Europe a short train ride from Brussels - is the conference venue.

However, little is known about user characteristics, adherence, attrition, and predictors of repeated participation on open access physical activity websites. Objective: The focus of this study was Active-online, a Web-based individually tailored physical activity intervention. The aims were (1) to assess and compare user characteristics and adherence to the website (a) in the open access context over time from 2003 to 2009, and (b) between trial participants and open access users; and (2) to analyze attrition and predictors of repeated use among participants in a randomized controlled trial compared with registered open access users. Methods: Data routinely recorded in the Active-online user database were used. Adherence was defined as: the number of pages viewed, the proportion of visits during which a tailored module was begun, the proportion of visits during which tailored feedback was received, and the time spent in the tailored modules. Adherence was analyzed according to six one-year periods (2003-2009) and according to the context (trial or open access) based on first visits and longest visits. Attrition and predictors of repeated participation were compared between trial participants and open access users. Results: The number of recorded visits per year on Active-online decreased from 42,626 in 2003-2004 to 8343 in 2008-2009 (each of six one-year time periods ran from April 23 to April 22 of the following year). The mean age of users was between 38.4 and 43.1 years in all time periods and both contexts. The proportion of women increased from 49.5% in 2003-2004 to 61.3% in 2008-2009 (P .001). There were differences but no consistent time trends in adherence to Active-online. The mean age of trial participants was 43.1 years, and 74.9% were women. Comparing contexts, adherence was highest for registered open access users. For open access users, adherence was similar during the first and the longest visits; for trial participants, adherence was lower during the first visits and higher during the longest visits. Of registered open access users and trial participants, 25.8% and 67.3% respectively visited Active-online repeatedly (P .001). Predictors of repeated use were male sex (odds ratio = 1.2, 95% confidence interval = 1.04-1.38) and increasing age category in registered open access users, and age 46-60 versus 30 years (OR = 3.04, 95% CI = 1.25-7.38) and Swiss nationality (ORnonSwiss = 0.64, 95% CI = 0.41-1.00) in trial participants. Despite reminder emails, attrition was much higher in registered open access users compared with trial participants, with a median lifetime website usage of 0 days in open access users and 290 days in trial participants. Conclusions: Adherence, patterns of use, attrition, and repeated participation differed between trial participants and open access users. Reminder emails to encourage repeated participation were effective for trial participants but not for registered open access users. These issues are important when interpreting results of randomized controlled effectiveness trials. ============================================ NEWS ANNOUNCEMENTS http://www.jmir.org/announcement __Forthcoming Theme Issue on e-Mental Health (NEW DEADLINE!)__ The organizers of the e-Mental Health Summit (the Trimbos-institute, VU University and University of Amsterdam and the International Society for Research in Internet Interventions board) in collaboration with Gunther Eysenbach, editor-in-chief of JMIR, are pleased to invite summit presenters to submit their paper for a special issue on e-mental health in the Journal of Medical Internet Research (JMIR, www.jmir.org).

Eysenbach) ------------------ Web Usage Data as a Means of Evaluating Public Health Messaging and Outreach Hao Tian, Dana J Brimmer, Jin-Mann S Lin, Abbigail J Tumpey, William C Reeves J Med Internet Res 2009 (Dec 21); 11(4):e52 HTML (open access): http://www.jmir.org/2009/4/e52/ PDF (members only): http://www.jmir.org/2009/4/e52/PDF Background: The Internet is increasing utilized by the public to seek medical information. As a result, an increasing number of health-related websites are created to disseminate health information and interventions to the public. Understanding how people use the website is critical for website developers to provide better services to the intended users. Objective: To examine the utilization of the chronic fatigue syndrome (CFS) website at Centers for Disease Control and Prevention. We measured outcomes of the CFS public awareness outreach via the website and analyzed user behavior in terms campaign materials and continuing education courses. Methods: We collected web usage data over an 18-month period and extracted page views, visits, referring domains, and geographic locations to describe and evaluate web utilization. We used pages views as the primary measure for the CFS awareness outreach effort. Market basket analysis and Markov chain model techniques were used to study user behavior related to utilization of campaign materials and continuing medical education courses. Results: The CDC CFS website received 3,647,736 views from more than 50 countries over an 18-month period. Among 71% referred by web search engines Google accounted for approximately 73% of search engine referrals to the website. A sharp increase and a quick drop in web traffic were observed around the launch of a CFS public awareness campaign. Visitors preferred longer radio clips of public service announcements over shorter ones and user interest shifted from areas targeting consumer basic knowledge to information for healthcare professionals following the campaign. Conclusions: Web usage data showed that the CFS website was an important online resource for people seeking basic information about CFS and for those looking for professional information. The website was an effective means for providing health information about CFS and serves as an important public health tool for community outreach. ============================================ Do you have any end-of-grant / end-of-year funds to spend?

张海粟 这篇随笔是读了David D. Clark和Marjory S. Blumenthal的文章： Rethinking the design of the Internet : The end to end arguments vs. the brave new world 之后的简单思考，主要内容曾经在我以前的博客中有所说明，这里做了进一步的修订和补充说明。但是不论怎样，还只是片断的思考，部分内容肯定不甚准确，欢迎批评指正。 一、因特网具有何种特性使其获得了巨大成功？ 当今世界计算机和网络已经渗透到人类社会的方方面面，信息时代彻底改变着人们的生产和生活方式。当我们惊叹于这种巨大的变化同时，常常会为因特网的成功究竟缘由何方而思考。也许不同专业背景的人从不同的角度来看有不同的答案。因为计算机网络成功归功于的因素太多，既有PC机、操作系统、光纤通信、以太网、网络应用技术大发展起的基础支撑作用；也是计算机设计制造商、操作系统生产商、网络建设维护商、应用程序厂商和内容提供商等商业实体在市场上的成功运作的结果；还有政府、非赢利组织、个人用户热衷于网络的推广应用的不可或缺的推动作用。计算机网络的发展咄咄逼人，在与传统电信网、有线电视网的竞争中出现了融合（甚至吞并）的态势，连电力网似乎都要向上靠近。那么如何拨开这些不同因素缠绕的迷雾，因特网的发展究竟与其自身的那些性质有关？ 在阅读了关于端到端原则的这篇经典文献后，我似乎看到了重重迷雾中间的一束清新阳光，这束阳光简单地照亮了人们的思维，因为其昭示了因特网有着促使自身的发展、立于不败之地（尽管计算机网络底层曾经基于X.25，出现过ATM等结构，再到以太网、光纤网，趋向IP over DWDM的全光网，现在计算机网络依然依靠TCP/IP完美地覆盖了这些底层网络的不同特性）的根本因素。结合我自己在通信网方面工作的粗浅感知，个人认为，这个因素是因特网设计之初就表现出来的对网络用户的平等看待、利于创新的特性，因特网的大发展也是基于端到端原则所支撑的因特网创新哲学、冒险精神实践后的必然结果。 今天又看到了一段精彩的话（RESTful web services，Leonard and Sam，徐涵等译，电子工业出版社），摘抄如下： 若不是得益于分配不当的国防资金、创新的工程项目、差点则更好的工程实践、大科学、天真的自由理想主义、古怪的自由主义政治、技术迷信，以及那些认为自己找到了发财之路的程序员和投资者的汗水与资本，因特网和万维网也许不一定会诞生。 二、端到端原则是什么？ 自Jerome Saltzer, David Clark and David P.Reed在1981年提出端到端原则以来，其普遍指导了网络设计者开发网络协议及应用程序。从理解的角度来说，遵循端到端原则的网络设计思路应该是这样的：如果一种机制能在端系统实现，那么就不应该将其在网络核心中实现，网络核心应该尽可能提供通用的服务，而具体应用相关的功能应该避免在网络核心中出现。端到端原则旨在让客户机承担网络应用的开发和创新，而让网络本身保持相对简单。这种相对简单的核心网络模型也是网络能够在上层变换实现不同应用的技术基础，确保网络能够被位于边缘的用户扩展新的应用功能。端到端原则的显著好处是保持了因特网的伸缩性、通用性和开放性。具体说，其一，核心网的复杂性得以降低。其二，网络容易支持新应用程序。其三，增加了网络应用的可靠性。（原文中关于对端到端原则的理解已有详细说明，此处不再赘述。） 三、端到端原则给因特网带来了什么？ 端到端原则指导了因特网的体系结构设计 因为网络应用能够迅速在边缘网上开发、运行、产生效益，无需对核心网进行改动，所以因特网上不断创新的应用能够应运而生，发展了资源共享、通信、游戏、信息发布等各种各样丰富多彩的应用模式，成为因特网得以被普通用户广泛使用的根本原因。 图1 因特网的创新模式 基于端到端原则的因特网创新模式使用户能够自由发布自己的新的网络应用功能，其他相关的用户可以选择使用这种应用功能，也可以选择不使用这种应用功能。如图1所示，这个创新的过程并不会受到网络的制约，也就意味着不再受到传统电信网中的网络强权（如ISP）提供的通信服务的制约。对于习惯了使用电信网的用户来说，这种创新功能带来的是一个真正的新世界。电信网上不论是电话还是电报，也不论电话提供了怎样的增值服务，要让一个普通用户发布这样的创新应用或者思想是完全不可能的。 端到端原则突出了因特网的冒险精神 因特网的冒险精神体现在多个方面。其一就是是上述的用户创新过程，这是典型的冒险之举。因为尽管存在着获利的可能，但是真正能够风靡的创新应用（比如QQ和BT之类的成功者）只是极少部分。其二，因特网上用户的行事原则更多的是自我约束，国家和权威机构的介入力度不够，介入难度也很大，因此这似乎给用户之间冒险性的竞争提供了温床。这种竞争导致所有用户都倾向于使用功能更加强大的软件，倾向于更好地保护自己的信息和其他利益，同时也就有人倾向于攫取他人的正当利益。其三，因特网是风险投资非常活跃的领域，这是因特网商业化能够发展起来的基本源泉。正是端到端的设计原则，包括游戏、聊天和P2P等在内的风险投资不需要在ISP的支配下进行，而只需要和端用户打交道即可。从产业链角度来说，如图2、图3所示，哭泣曲线转变成了微笑曲线（资料来自于中国通信企业联合会《2006年信息产业发展研究报告》）。图3说明现在位于产业链上方的服务提供商利润高于位于产业链中部的ISP。具有讽刺意味的刺激作用是，这甚至反过来促使各ISP积极向信息服务商的角色积极进行转型。 图2 哭泣曲线 图3 微笑曲线 四、端到端原则在因特网上的发展趋势怎样？ 原文中说明了端到端的原则受到了不少挑战。这些挑战可能会该端到端的原则带来损害，但是正如作者坚持的那样，端到端原则不应该被放弃，而应该被逐渐改良。 端到端的原则受到损害的根源是什么 原文也注意到端到端原则的损害很大程度上是由于各方利益的纠纷所带来的，因此着重提出了要注意把握以下各方之间的相关利益：一是利用端到端原则进行通信的终端用户之间；二是终端用户和因特网服务提供商之间；三是终端用户、ISP和第三方之间。显而易见，这里各方的关注焦点在于对网络功能的需求逐渐变化和丰富（如需要QoS保证的多媒体、实时通信等；需要更加坚固的安全保障；需要向用户提供更快的服务，等等）。而因特网随着规模的增大，用户间的信任关系却已经很难建立（引入认证机构还是加密能够解决此问题？）。从ISP、政府机构积极介入因特网的态度来看，尤其是ISP期望能够向信息服务转型的愿望会给因特网端到端原则带来最本质的冲击。也许ISP最期望看到的就是因特网不仅从技术上和电信网融合，而且从服务模式甚至赢利模式上也统一到经典的电信网模式上？尽管这听起来不太可能，但是这正是原文作者认为现有因特网的大量投资隐藏于网络中使得ISP和ICP都倾向于短期效益行为的潜台词。 端到端的原则不会被抛弃 前文已经反复强调了因特网发展壮大的原因和因特网的创新精神、冒险哲学，以及基于端到端原则建立起来的因特网体系结构，这些都是端到端原则不会被抛弃的强有力保证。试想象一个不符合端到端原则的计算机网络还是因特网吗？用户也许就不再认识这样的因特网了。 但是端到端原则必须要着眼于解决如何满足前一小节提出的各种需求，必须能够满足ISP和政府等第三方对网络期望进行操作的要求。因此，因特网的端到端原则在逐渐地向着一系列相互合作的原则过渡因特网不再是一揽子不管用户行为的端到端原则的尽力而为服务，而以网络为中心的新模式也能够在网络中间逐渐建立起来。不久的将来，也许用户可能就会习惯于在ISP提供的业务和单纯的ICP提供的服务之间转变，但是用户自身创新的新应用业务还必将会受到ISP的核心网的支持。
In compare witn the PC Internet,handheld Internet is at least engaged in two shortages. one is the size of cell-phone's screen;they can't display stand Web pages.It should be to reformat Web pages on the fly,so that they fit the device. The other major hurdle to be overcome is the cell phone's negligible memory. its network software may be rebuilt in order to as much information as possible will be stored on the server,rather than on the phone's limited menory. Though this tast is not an easy one,the Internet is a whole different animal when you're looking at it on a cell phone.And Internet economy will give us a good,strong whiff of the future.
