HBO will lead AT&T"s challenge to Netflix

Time Warner"s crown jewel must scale up while maintaining quality

IN LATE 2012, just before the release of “House of Cards”, Ted Sarandos, chief content officer of Netflix, declared: “The goal is to become HBO faster than HBO can become us”. Few took him seriously. HBO had a globally recognised brand with some of the best programmes in television, including “Game of Thrones”. Yet Netflix would go on to surpass HBO in subscribers, money spent on programming and, this year, Emmy-award nominations.

Meanwhile HBO did not try to become Netflix. It prioritised profits over growth as Jeff Bewkes, then chief of Time Warner, HBO"s parent, looked to sell the company. HBO achieved enviable operating-profit margins of 30-40% ($2.2bn on $6.3bn of revenue in 2017), and was comparatively restrained in its pursuit of high-profile shows (Netflix committed $100m in outbidding HBO for “House of Cards”, and was ridiculed for it). The network also lagged behind in the technologies of personalisation and streaming that made Netflix a killer app. At one point Reed Hastings, boss of Netflix, puckishly joked that the password used by Richard Plepler, his HBO counterpart, for online access was “Netflix bitch”.

Now HBO is preparing to launch its counter-attack, backed by a phone giant. In June AT&T finalised its $109bn purchase of Time Warner. The wireless firm, which is also America"s largest distributor of pay-TV, views itself as locked in an existential battle with Netflix, Amazon, Facebook and Google for people"s attention. Facebook and YouTube each command screen time from about 2bn users a month, while Netflix wins about two hours of viewing a day per subscription. With its newly-acquired media assets, AT&T wants to match that kind of engagement.

Ma Bell rides out

AT&T is pinning its hopes in part on a new subscription streaming service to be rolled out in 2019 under Time Warner"s new banner of WarnerMedia. A bigger HBO will be the “cornerstone” of that strategy, says John Stankey, boss of WarnerMedia. The phone firm hopes video customers will become wireless customers, and vice versa, driving down both churn and the cost of acquiring subscribers. It will join a crowded field: Disney and Apple are launching streaming-video services next year.

HBO is not far behind Netflix in subscribers, with more than 100m worldwide (142m when counting subscribers to Cinemax, HBO"s other premium service), including about 40m subscribers in America. Netflix has nearly 60m subscribers in America and 137m globally. But most of HBO"s customers are acquired through a third-party distributor, depriving it of direct customer relationships and data.

Under AT&T, HBO will have a better crack at both. AT&T already offers HBO-over-the-internet in America in high-end wireless plans and in packages with DirecTV Now, a streaming pay-TV service (and will do the same with its new streaming product). Eventually AT&T will allow HBO to sell more directly to consumers around the world. With accompanying investments in technology HBO should get a lot more data about what those subscribers are watching.

And the new HBO will have a lot more shows to watch. Its budget for programming had grown at a snail"s pace under Time Warner, to $2.3bn in 2017; Netflix increases its spending on programming by an entire HBO or more each year, to $12bn-13bn in 2018. Under AT&T, HBO will spend several hundred millions more on original programming next year, and more than that thereafter. Mr Plepler, who has fretted in the past that he could not say “yes” to everything he wanted, has already started saying “yes” to a lot more. HBO"s slate of big-budget shows in the coming years now includes adaptations of “The Time Traveller"s Wife”, “His Dark Materials” and “Watchmen”. HBO is also developing a prequel to its biggest hit, “Game of Thrones”. Mr Stankey says he wants “a more muscular HBO” that engages customers so regularly that they consider it important enough to keep year round.

But HBO will not try to muscle its way into becoming another Netflix, which releases hundreds of original feature films, documentaries and series a year. Netflix sells its product on volume, personalisation and ease of user experience. HBO by contrast wins subscribers through a few hit shows and a reputation for quality television, which could be wrecked by an over-rapid expansion. As the network"s margins may be eroded in the near term, AT&T will need to be cautious. WarnerMedia will already take a hit to revenues as it pulls its content from Netflix to beef up its offer.

Yet HBO will still face a challenge to maintain its reputation as it expands. One Hollywood executive reckons that its schedule of original shows is about to double in size in the next few years. Among TV networks, he says, “I don"t think anybody has ever tried to scale it at the level that HBO is attempting to scale it.”

AT&T"s bosses show signs of understanding this. Randall Stephenson, its chief executive, has referred to HBO as Tiffany"s to Netflix"s Walmart. Still, making the transition under AT&T will not be easy. In June Mr Stankey told a gathering of HBO employees that the year ahead would be such hard work at times that “it feels like childbirth”. AT&T is expected to surround HBO"S programmes with a variety of assets from WarnerMedia, from Warner Bros studio"s films (such as “The Dark Knight”) and TV shows (like “Friends”) to Turner"s library of classic films. Under Time Warner those assets were farmed out to a wide array of outlets including Netflix, HBO, Cinemax, Turner"s cable networks and niche streaming services like FilmStruck (which will shut this month). If they are consolidated in one streaming product, to be sold alongside HBO, subscribers would in theory have something else to watch between servings of “True Detective” and “Westworld”. “There are nights you want to go to a four- or five-star restaurant,” Mr Stankey says. “But we also know there are nights where you want to get a cheeseburger.”

vue中token如何进行刷新处理

本篇文章给大家分享的是关于vue中token如何进行刷新处理,内容很不错,有需要的朋友可以参考一下,希望可以帮助到大家。token身份验证机制客户端登录请求成功后,服务器将用户信息(如用户id)使用特殊算法加密后作为验证的标志发送给用户(即token),当用户下次发起请求时,会将这个token捎带过来,服务器再将这个token通过解密后进行验证,通过的话,则向客户端返回请求的数据;反之,则请求失败。token优点它是无状态的,且服务器不用像传统的身份认证(session)那样需要保存会话信息,减轻了服务器的压力。vue的token刷新处理在对token身份验证机制进行一次简单介绍后,进入正文...一般为了安全性,token都会设置一个过期时间,在过期之后就无法请求相关接口了,这时应该怎么办呢,是直接退出登录吗?在目前公司的项目里,为了更好的用户体验,我们选择手动刷新token。登录请求成功后,会返回一个token和token过期时间,在每次请求api时,前端可以先判断一下token是否即将过期或已过期,如果是,则请求刷新token的接口,成功替换原来的token之后才可以重新发起请求。下面,我们直接看代码,这是在vue的请求拦截器里进行的相关操作:/*是否有请求正在刷新token*/window.isRefreshing = false/*被挂起的请求数组*/let refreshSubscribers = []/*获取刷新token请求的token*/function getRefreshToken () { return JSON.parse(localStorage.auth).refresh_token}/*push所有请求到数组中*/function subscribeTokenRefresh (cb) { refreshSubscribers.push(cb)}/*刷新请求(refreshSubscribers数组中的请求得到新的token之后会自执行,用新的token去请求数据)*/function onRrefreshed (token) { refreshSubscribers.map(cb => cb(token))}/*请求拦截器*/ajax.interceptors.request.use( config => { const authTmp = localStorage.auth /*判断是否已登录*/ if (authTmp) { /*解析登录信息*/ let auth = JSON.parse(authTmp) /*判断auth是否存在*/ if (auth) { /*在请求头中添加token类型、token*/ config.headers.Authorization = auth.token_type + " " + auth.token /*判断刷新token请求的refresh_token是否过期*/ if (util.isRefreshTokenExpired()) { alert("刷新token过期,请重新登录") /*清除本地保存的auth*/ localStorage.removeItem("auth") window.location.href = "#/login" return } /*判断token是否将要过期*/ if (util.isTokenExpired() && config.url.indexOf("admin/auth/current") === -1) { /*判断是否正在刷新*/ if (!window.isRefreshing) { /*将刷新token的标志置为true*/ window.isRefreshing = true /*发起刷新token的请求*/ apiList.refreshToken({refresh_token: getRefreshToken()}).then(res => { /*将标志置为false*/ window.isRefreshing = false /*成功刷新token*/ config.headers.Authorization = res.data.data.token_type + " " + res.data.data.token /*更新auth*/ localStorage.setItem("auth", JSON.stringify(res.data.data)) /*执行数组里的函数,重新发起被挂起的请求*/ onRrefreshed(res.data.data.token) /*执行onRefreshed函数后清空数组中保存的请求*/ refreshSubscribers = [] }).catch(err => { alert(err.response.data.message) /*清除本地保存的auth*/ // localStorage.removeItem("auth") window.location.href = "#/login" }) } /*把请求(token)=>{....}都push到一个数组中*/ let retry = new Promise((resolve, reject) => { /*(token) => {...}这个函数就是回调函数*/ subscribeTokenRefresh((token) => { config.headers.Authorization = "Bearer " + token /*将请求挂起*/ resolve(config) }) }) return retry } } return config } else { /*未登录直接返回配置信息*/ return config } }, /*错误操作*/ err => { return Promise.reject(err) })这里需要注意几点:1、当token即将过期或者已过期时,原则上,我们只需要有一个接口去触发刷新token的请求即可,这里的isRefreshing 变量,就起到这样一个监控的作用,它相当于一把锁,当刷新token的操作被触发后,其他的触发操作就被排斥在外了。window.isRefreshing = false2、刷新token的接口,用到了一个另外的token(refresh_token),这也是出于安全性考虑的,并且它也有过期时间,不过这个过期时间一般都比普通token的过期时间要长,所以在上面代码中,会发现,我在请求拦截中优先判断了refresh_token是否过期,如果过期则直接退出登录,不再进行下一步的操作。 /*判断刷新token请求的refresh_token是否过期*/if (util.isRefreshTokenExpired() && config.url.indexOf("admin/auth/current") === -1) { alert("刷新token过期,请重新登录") /*清除本地保存的auth*/ localStorage.removeItem("auth") window.location.href = "#/login" return}3、在触发了刷新token的操作后,我们还需要先将其他的请求挂起,在获取新的token之后再重新发起这些请求。/*把请求(token)=>{....}都push到一个数组中*/let retry = new Promise((resolve, reject) => { /*(token) => {...}这个函数就是回调函数*/ subscribeTokenRefresh((token) => { config.headers.Authorization = "Bearer " + token /*将请求挂起*/ resolve(config) })})return retry在刷新token请求的成功回调里执行下面代码,重新发起请求。 /*执行数组里的函数,重新发起被挂起的请求*/ onRrefreshed(res.data.data.token)4、因为有人在评论里问util文件,应该是想知道具体怎么判断token过期的,其实在获得token时,是有返回一个token过期时间 ,你可以先将它先保存起来,然后在需要时,拿出来与本地时间比较即可/*判断token是否过期*/function isTokenExpired() { /*从localStorage中取出token过期时间*/ let expiredTime = new Date(JSON.parse(localStorage.auth).expired_at).getTime() / 1000 /*获取本地时间*/ let nowTime = new Date().getTime() / 1000 /*获取校验时间差*/ let diffTime = JSON.parse(sessionStorage.diffTime) /*校验本地时间*/ nowTime -= diffTime /*如果 < 10分钟,则说明即将过期*/ return (expiredTime - nowTime) < 10*60}

高三英语阅读理解

高三英语阅读理解   要提高英语的阅读理解就要多练习,以下是我收拾整理的高三的英语阅读理解练习题和答案,希望能帮助到大家!   第一篇:   Shopping for clothes is not the same experience for a man as it is for a woman. A man goes shopping because he needs something. His purpose is settled and decided in advance. He knows what he wants, and his objective is to find it and buy it; the price is a secondary consideration. All men simply walk into a shop and ask the assistant for what they want. If the shop has it in stock, the salesman promptly produces it, and the business of trying it on follows at once. All being well, the deal can be and often is completed in less than five minutes, with hardly any chat and to everyone"s satisfaction.   For a man, slight problems may begin when the shop does not have what he wants, or does not have exactly what he wants. In that case the salesman, as the name implies, tries to sell the customer something else, he offers the nearest he can to the article required. No good salesman brings out such a substitute impolitely; he does so with skill: “I know this jacket is not the style you want, sir, but would you like to try it for size? It happens to be the color you mentioned.” Few men have patience with this treatment, and the usual response is: “This is the right color and may be the right size, but I should be wasting my time and yours by trying it on.”   Now how does a woman go about buying clothes? In almost every respect she does so in the opposite way. Her shopping is not often based on need. She has never fully made up her mind what she wants, and she is only “having a look round”. She is always open to persuasion; indeed she sets great store bywhat the saleswoman tells her, even by what companions tell her. She will try on any number of things. Uppermost in her mind is the thought of finding something that everyone thinks suits her. Contrary to a lot of jokes, most women have an excellent sense of value when they buy clothes. They are always on the lockout for the unexpected bargain. Faced with a roomful of dresses, a woman may easily spendan hour going from one rail to another, to and fro, often retracing her steps, before selecting the dresses she wants to try on. It is a laborious process, but apparently an enjoyable one. Most dress shops provide chairs for the waiting husbands.   17. The passage mainly talks about ________.   A. differences between men and women shoppers   B. A man goes shopping because he needs something   C. How women go about buying clothes.   D. Women are better at shopping than men   18. The underlined sentence “the price is a secondary consideration” in the first paragraph means when a man is shopping ________.   A. he buys good quality things, so long as they are not too dear   B. he buys whatever he likes without considering its value   C. he does not mind how much he has to pay for the right things   D. he often buy things without giving the matter proper thought.   19. What does a man do when he can not get exactly what he wants?   A. He buys a similar thing because of the color he wants.   B. He usually does not buy anything.   C. At least two of his requirements must be met before he buys.   D. So long as the style is right, he buys the thing.   20. What is the most obvious difference between men and women shoppers?   A. Men do not try clothes on in a shop while women do.   B. Women bargain for their clothes, but men do not.   C. The time they take over buying clothes.   D. Men go shopping based on need, but women never.   第二篇:   A little under one-third of U.S. families have no Internet access and do not plan to get it, with most of the holdouts seeing little use for it in their lives, according to a survey released on Friday.   Park Associates, a Dallas-based technology market research firm, said 29 percent of U.S. families, or 31 million homes, do not have Internet access and do not intend to subscribe(预订)to an Internet service over the next 12 months. The second annual National Technology Scan conducted by Park found that the main reason why potential customers say they do not subscribe to the Internet is because of the low value to their daily lives rather than concerns over cost.   Forty-four percent of these families say they are not interested in anything on the Internet, versus just 22 percent who say they cannot afford a computer or the cost of Internet service, the survey showed. The answer “Iu2019m not sure how to use the Internet” came from 17 percent of participants who do not subscribe. The response “I do all my e-commerce shopping and YouTube-watching at work” was cited by 14 percent of Internet-access users. Three percent said the Internet doesnu2019t reach their homes.   The study found U.S. broadband adoption grew to 52 percent over 2006, up from 42 percent in 2005. Roughly half of new subscribers converted(转变)from slower-speed, dial-up Internet access while the other half of families had no prior access.   “The industry continues to chip(击破)away at the core of non-subscribers, but has a long way to go,” said John Barrett, director of research at Parks Associates. “Entertainment applications will be the key. If anything will pull in the holdouts, itu2019s going to be applications that make the Internet more similar to pay-TV,” he predicted.   1. What does the underlined word “holdouts” in the first paragraph most probably mean?   A. some American families   B. those who hold out oneu2019s opinions   C. those who have been surveyed   D. those who still havenu2019t access to the Internet currently   2. Many potential customers refuse to subscribe to the Internet mainly because _________.   A. they show too much concern about the cost B. they can find little value of it   C. they do most YouTube-watching at work D. the Internet doesnu2019t reach their homes   3. From the passage we can infer that ________.   A. It is not an easy job to transform those holdouts into the Internet users   B. people will adopt dial-up Internet access no more   C. many Americans enjoy doing e-commerce shopping at home   D. more than half of the population are using the Internet in 2005   4. According to John Barrett, what is the key to attracting more U.S. families to broadband service?   A. making the Internet look more similar to TV set   B. applying the Internet more to entertainment   C. providing more pay-TV programs   D. chipping away at the core of non-subscribers   5. Which is the best title for the passage?   A. Web develops with technology B. The present situation of web   C. Many Americans see little point to web D. It is urgent to promote web service   >>>>>>参考答案<<<<<<   第一篇:   17. A 主旨大意题。文章首句 Shopping for clothes is not the same experience for a man as it is for a woman 点题男人买衣服和女人买衣服是不同的经历。然后下文分别阐述男人和女人买东西的不同。故答案为 A。   18. C 语义理解题。根据第1段第 2、3、4 句 A man goes shopping because he needs something. His purpose is settled and decided in advance. He knows what he wants, and his objective is to find it and buy it 可知男人因为需要而买东西,他买东西的目的预先订下来,他知道他需要什么,而且他的目标是找到他需要的东西并买下来。由此可推断只要东西合适,是他需要的,价格则是次要的事情。故答案为 C。   19. B 推理判断题。根据第3段首句 For a man, slight problems may begin when the shop does not have what he wants, or does not have exactly what he wants. 和末句This is the right color and may be the right size, but I should be wasting my time and yours by trying it on 可知虽然价格和颜色都合适,但如果不是他想要的东西,他认为“试穿是浪费时间”,因此可推知他不会买。故答案为 B。   20. C 推理判断题。根据第1段 the deal can be and often is completed in less than five minutes 和第3段中 a woman may easily spend an hour going from one rail to another 可推知男人和女人买东西的`明显不同是他们所用的时间不同。本文阐述如何在参加面试的前几分钟时间里给人留下深刻的印象。   第二篇:   1. D 根据前文one third of the U.S. families have no Internet access and do not plan to get it 可知   2. B 由第二段u2026u2026found the main reason potential customers say they do not subscribe to the Internet is because of the low value to their daily lives they recognizeu2026u2026可知   3. A 从最后一段第一句可知   4.

详解vuex中action何时完成以及如何正确调用dispatch的思考

在项目中遇到关于action与dispatch使用的一些细节问题,经过搜索得到了一些答案。特意在此提出,如有错误还请指出,十分感谢~问题1:如果action是异步的,那么怎么知道它什么时候完成?在vuex的官网给出了答案:注:如果需要通过组合多个action来完成某些逻辑,用async/await会更简单一点问题2: 如果action是同步的,就不需要等待它完成了吗?其实这个问题相当于在w:dispatch("some action")是一个同步函数还是异步函数。如果dispatch是一个异步函数(返回一个promise),那么即使action里面的逻辑是同步的,如果需要等待这个action完成之后才进行某些操作,仍然是需要用异步等待dispatch().then(()=> {})来实现通过查看vuex的源码找到了答案: dispatch (_type, _payload) { // check object-style dispatch const { type, payload } = unifyObjectStyle(_type, _payload) const action = { type, payload } const entry = this._actions[type] if (!entry) { if (process.env.NODE_ENV !== "production") { console.error(`[vuex] unknown action type: ${type}`) } return } try { this._actionSubscribers .filter(sub => sub.before) .forEach(sub => sub.before(action, this.state)) } catch (e) { if (process.env.NODE_ENV !== "production") { console.warn(`[vuex] error in before action subscribers: `) console.error(e) } } const result = entry.length > 1 ? Promise.all(entry.map(handler => handler(payload))) : entry[0](payload) return result.then(res => { try { this._actionSubscribers .filter(sub => sub.after) .forEach(sub => sub.after(action, this.state)) } catch (e) { if (process.env.NODE_ENV !== "production") { console.warn(`[vuex] error in after action subscribers: `) console.error(e) } } return res }) }dispatch函数返回的是一个promise,所以dispatch后如果需要跟进操作(比如dispatch里面commit了一个state,后续要用到这个state),正确的做法应该是需要用异步的方式来完成后续的逻辑注:用同步的写法看起来好像state也是对的,但可能只是恰好我的业务场景io使用不是很高所以"看起来是对的",严谨的做法应该还是需要用异步来完成后续操作的

谁那里有全面的媒介专用术语

节目套餐(Package) 广告主所能提供的一整套节目。传阅读者(Pass Along Readers)非经由购买或订阅而看到杂志刊物的读者。普及率(Penetration)拥有电视或收音机之家庭数所占之百分比。黄金时间(Prime Time)电视之高峰收视时间,通常以晚上为多。拉式推广战略(Pull Strategy)推式推广战略(Push Strategy)综合浏览量(Page Views)网站各网页被浏览的总次数。一个访客有可能创造十几个甚至更多的Page Views。就是说假如有1000人次(User Sessions)访问你的网站,而Page Views是1200的话,那就说明其中有一些人看了2次以上这个网页。收费标准是Page Views而不是User Sessions,因为假如其中一个人看了2次以上这个广告的话,这个广告也就起到了相应的作用,就像电视广告一个晚上放了3次,也是按3次收费,虽然可能是被同一个人看到。点击广告后连到的页面(Portal Page)通常这个页面不是商家网的首页,而是针对广告内容重新设计的页面。价格保障(Rate Protection)广告主与媒体签约期间内,即使广告费上涨,广告主仍以原签约价格支付。收视(听)率(Rating)指收看(听)某一电视节目(广播节目)的人数或家庭户数占拥有电视机(收录机)的总人数或家庭户数的百分比。到达率(Reach)媒体所涵盖之阅听者总数;视听众的总人数。到达率不考虑重复。到达率的提高意味着载体的传播广度在增加,覆盖范围在扩大,广告宣传的产品的知名度会扩大。阅读率(Readership)阅读刊物或广告之读者人数或其所占之百分比。Number(%) of a target audience who claim to have “read” a publication(N.B.read after means looked into).传阅读者(Pass-Along Readers)阅读自己没有购买的刊物的读者(Readers of magazine who are not purchases/subscribers)。回扣(Rebate)媒体支付给广告主的退款,即支付款额与签订价格间的差额。节目视听众占有率(Share)人们通常会问,在所有看电视的人中,有多少人在看我的节目?节目视听众占有率是指某一节目,其收看者占开机者的百分比占有率=收看某一频道(节目)的观众人数÷所有正在看电视人数×100或占有率=某一频道(或节目)收视率÷所有频道收视率×100声量份额(Share of Voice/Share of Spending)某产品在其同类产品中的广告活动份额,用投入的经费来衡量(SOS-share of spending)或用出现在媒介的比重来衡量(SOV-share of voice计算单位通常为GRP)。广告排期表(Schedule)广告活动中所使用之媒体或广告时间、版面之列表。分刊法(Split Run)报刊广告中,将一位广告主的两种或多种不同的广告分刊于同期的各版次上,以测定各广告的效果。节目提供者(Sponsor)购买某一节目或节目片段广告独占权的广告主。插播广告(Spot)依地理分区或电台分区购买广告时段插播;节目中插播。(Spot)可为播映广告的时间或指广告本身。联合播出辛迪加(Syndication)联合播出是基于以每个地域市场的联合节目统筹播出安排方法,与常规的联线或以人造卫星传输节目不同。联合播出可由独立制片人、广告主、广告公司或联合发行公司负责。联合发行的节目可以是任何类型、任何长短的持续时间,并可日夜播出。联合播出的节目在联播网盟台播出时,通常都是在傍晚时段(下午4:00-7:30)、特级时段(周一至周六晚8:00-10:00,周日晚7:00-11:00)、甲级黄金时段(周日至周六晚7:30-8:00)播出。电视联播网(TV Network ,Television Broadcast Network)联播网是由任何组群的电视台联合播送相同的节目。美国有三个电视联播网,即ABC(美国广播公司 American Broadcasting Company)、CBS(哥伦比亚广播公司Columbia Broadcasting System)、NBC(国家广播公司National Broadcasting Company)。加入这些联播网的电视台与联播网签合约,按约每周播出一定数量的联播网节目,通常约55-60小时。目标群(Target Group)广告活动诉求对象:拥有类似特性的未来对象。撕页(Tear-Sheet)送给广告主核准或签核的的广告单页。悬疑广告(Teaser)广告活动中,企图使读者产生好奇心理的广告。裁切后尺寸(Trim Size)经裁切后之杂志大小。电话营销(Telemarketing)非重复视听众(Unduplicated Audience)累积视听众。独立访客(Unique Host)在网络广告中,由于每个访客可制造出多个Pageviews,而访客刷新网页也会使Impression数增,所以Pageviews或Impression都不能精确表现网站的访问人数。通常情况下每个访客都会来自于不同的地址,称为来自不同的IP。独立访客即将来自同一IP的访客视为同一个人,从而获得更精确的访客人数。像网易中文排行榜提供的易数统计所提供的数字就是Unique Host。通常很多网站公布的访问量都是Pageviews或Impression,Pageviews往往是Impression的数倍,而Impression又会比UNIQUE HOST高出很多。媒体(Vehicle)广告中的某一具体传播媒介。如杂志或某电视台(A specific carrier within a media category.)。浪费发行量(Waste Circulation) 不是产品或服务所要广告的未来顾客之刊物读者;未铺地区的发行量。

According to international routines, the popularization rate of Phone (Including Mobile Phone and telephone) should run up to 10 percent when the average GDP runs up to 1500 dollars.But China has exceeded this criterion with the average GDP only 900 dollars. Does this show that the development of Chinamobile Communication Bussiness runs too fast? Or that this criterion is improved along with the need of informationization? Incontestable facts show that Chinese informationization level is far lower than that of developed countries, for the world has entered into an informationized and international time! So, the development of Chinamobile Communication Bussiness should be increasing other than declining.According to a market survey in Beijing currently initiated by Xinhuaxin Marketing research & Counsultant company about using bases of newly increased mobile phone subscribers, During the first half-year of 2002, the propertion of the people aged within 30 to all the newly increased mobile phone subscribers is 80.5%,and the middle-income subscribers whose income being within 2000 present 80 percent of all. To some extent, this reflects the causes of the rapid increasing of Chinese mobile phone subscribers:even the income of young people is low, they have light burden of family and life, and they pay attention to daily communation with each other in their life, and their need of grasping information of jobs and interests is strong. Among them the student groups have the parents as their firm supporter. In summary, the development of Chinamobile Communication Bussiness is potential, and the increasing young customers are becoming the main stream.

英语语法问题

hanging out and playing pokers现代分词状语修饰guys,just是修饰a couple of guys,与后面无关。不是,后面是一个单词,behaviour,有前置限定性定语perplexing和后置定语of the women in the plant。journal可以allow的,allow的主语不一定人呀,你可以百度翻译allow,查一些用法就明白了。before making it freely available to是正确的,而且必须省略journal。加上了从句结构不正确了。目的状语

如何开发一个自定义库

这次给大家带来如何开发一个自定义库,开发一个自定义库的注意事项有哪些,下面就是实战案例,一起来看一下。当然这个库还处在刚刚开始阶段,功能实现的比较简单,在此发表出来,欢迎大家借此为基础一起去完善它。项目地址:Hoz.js,欢迎大家start,fork,以及提issues。特点声明式的模板语法借鉴redux,flux等的思想,引入状态管理引入virtual dom,diff 算法,提高性能声明式语法 <p id = "app"> <p> <img src="{{moveImage}}" /> <p>{{moveName}}</p> </p> </p>var hoz = new Hoz("app", state, changeStore)var state = { moveName: "", moveImage: ""}function changeStore (state, action) { switch (action.type) { case "SET_NAME": { state.moveName = action.data break } case "SET_IMAGE": { state.moveImage = action.data break } }}hoz.store.dispatch({ type: "SET_NAME", data: "后来的我们"})这就是一个hoz应用,通过简洁的模板语法声明式的将数据渲染进DOM系统。且所有东西都是响应式的。借鉴redux,flux等的思想,引入状态管理在状态管理方面借鉴redux的思想,实现了单向数据流的管理。主要定义了state,action,changeStore,dispatch4个概念。state存放数据var state = { moveName: "", moveImage: ""}changeStore相当于redux中的reducer,存放着对数据的所有操作function changeStore (state, action) { switch (action.type) { case "SET_NAME": { state.moveName = action.data break } case "SET_IMAGE": { state.moveImage = action.data break } }}接收action,执行对应的方法,修改state中的数据。不同于redux的是,redux放回的是全新的state,而它是直接操作当前的state,因为state中的数据已经通过Object.defineProperty方法进行了跟踪,这个后面再将。action和dispatch当想要对数据进行修改的时候,我们必须通过提交action的方式,在changeStore中去修改statehoz.store.dispatch({ type: "SET_NAME", data: "后来的我们"})这个就是hoz的状态管理策略 view -> dispatch -> action -> changeStore -> state -> view好处随着应用的日益复杂,数据量的增大,如果不对数据进行相应的管理,管理不断变化的状态,是非常困难的。状态在什么时候,由于什么原因,发生了怎样的变化都难以观察。这意味着应用中所有的数据都遵循相同的生命周期,这样可以让应用变得更加可预测且容易理解。我们可以从 changeStore 中看到state能够发生的所有变化对state修改的唯一方式就是向changeStore提交action,所以数据的每一次变化都会从一个地方流过,方便我们的debug等操作。引入virtual dom 和diff算法总所周知,由于dom元素的庞大,以及dom操作容易引起页面重排的原因,直接操作dom性能是非常非常差的。所以hoz引入了virtual dom算法,用原生的JavaScript对象去映射dom对象,因为原生JavaScript对象的操作更快更简单。如何映射呢?比如class VNode { constructor (sel, tagName, id, className, el, children, data, text, key) { this.tagName = tagName // p this.sel = sel // p#id.class this.id = id // id this.className = className // [] this.children = children // [] this.el = el // node this.data = data // {} this.key = key this.text = text }}export default VNode只是一个JavaScript对象,代表一个dom元素。我根据hoz构造函数中传进来的 id 所指向的元素作为根元素建立一个虚拟dom树,当数据改变的时候,不直接操作dom,而是在虚拟dom树上进行操作修改。然后通过diff算法对比新旧虚拟dom树,对真实dom进行最小单位的修改。数据响应式原理hoz式如何做到数据的响应式的呢?这里主要通过借助Object.defineProperty方法实现了一个发布/订阅模式,通过Object.defineProperty修改state中数据的getter和setter属性,在首次渲染的时候,在getter中将对应的订阅者添加到一个主题对象中去,当数据改变的时候在setter中调用对应数据的主题对象的notify方法发布消息,通知每个订阅者更新。state -> data -> publisher 一对多的关系 | Dep |view -> {{data}} -> subscribers希望大家借此为基础一起去完善它。项目地址:Hoz.js,欢迎大家start,fork,以及提issues。相信看了本文案例你已经掌握了方法,更多精彩请关注Gxl网其它相关文章!推荐阅读:前端,HTT,计算机与网络webkit-font-smoothing字体抗锯齿渲染使用案例详解

redis pub/sub 一段时间之后接收不到消息

这是最主要的部分:This is how Pub/Sub works performance wise in Redis.You have two things.1) Subscribers to channels (SUBSCRIBE)2) Subscribers to *patterns* (PSUBSCRIBE)3) Publishers (PUBLISH)You can consider the work of subscribing/unsubscribing as a constanttime operation, O(1) for both subscribing and unsubscribing(actually PSUBSCRIBE does more work than this if you are subscribedalready to many patterns with the *same* client).All the complexity on the end is on the PUBLISH command, that performsan amount of work that is proportional to:a) The number of clients receiving the message.b) The number of clients subscribed to a pattern, even if they"ll notmatch the message.This means that if you have N clients subscribed to 100000 differentchannels, everything will be super fast.If you have instead 10000 clients subscribed to the same channel,PUBLISH commands against this channel will be slow, and take maybe afew milliseconds (not sure about the actual time taken). Since we haveto send the same message to everybody.Also, if you have clients subscribed to 10000 *patterns* publish willbe slower than usually, but the work to do for every existing patternis smaller compared to the work that there is to do for every client*receiving* the message.About memory, it is similar or smaller than the one used by a key, soyou should not have problems to subscribe to millions of channels evenin a small server.Salvatore

立等可取的意思

问题一:立等可取是什么意思 站在那儿稍等片刻就可以拿到 问题二:“立等可取”的“立”的意思 形容词,本意是站立,这里只坐下到站立的时间 形容非常快 问题三:港澳证立等即取两个月内一次是什么意思 港澳签“立等可取”有两个前提:一是必须是电子卡式港澳通行证,本式的通行证暂时不行;同时申请人员必须是非国家机关报备人员,一些需要经过单位审批的人员在此机器上无法当场取证。通过一体机办理签注同样有次数限制:最多你可以每两个月在自助一体机上办理两次去香港 、一次去澳门。 问题四:港澳证立等可取的意思是2个月内没去香港才能办理吗?比如我今天刚把2次机会用完,要2个月后才能办理 立等可取是本地户籍的在自助机办理才有的。 问题五:港澳通行证 立等可取 问题 50分 没间隔两个自然月是不能即签即取的 问题六:one-touch是什么意思? one-touch的意思是:触发的,立等可取的,即席的,速效的。 但现在一般来说,常常翻译成“一键式的” 例句: The phone"s facebook button glows when a song is playing to remind users that thisone-touch sharing is possible. 手机在播放歌曲时,facebook键会闪烁,提醒用户可以使用一键分享功能。 And should onstar subscribers need assistance with something that the mobile appsdon"t provide, they can one-touch dial to specially trained advisors, who are availableto assist customers 24 hours a day, seven days a week. 如果onstar用户需要程序未提供服务的帮助,便可一键拨打电话给我们的专业人员,他们一天24小时工作,全年无休。 问题七:DLINK中文是什么意思 ? 国际著名网络设备和解决方案提供商友讯集团(D-Link)成立于1986年,并于1994年10月在台湾证券交易所挂牌上市,为台湾第一家公开上市的网络公司,以自创D-Link品牌行销电脑网络产品遍及全世界100多个国家。作为世界领导品牌的网络和解决方案提供商,D-Link致力于局域网、宽带网、无线网、语音网、网络安全、网络存储、网络监控及相关网络设备的研发、生产和行销;在50多个国家设立了分公司并在美国、中国大陆、台湾及印度设有研究发展中心,产品遍及170多个国家,拥有众多美国和日本的世界级影响客户;2006年全球营业额为12.66亿美元,增长幅度高达15%,并获得全球消费类网络产品销量第一、全球SOHO宽带路由器销量第一、全球传统交换机销量第一及全球千兆传统交换机销量第一的桂冠,并再度入选美国《商业周刊》IT百强,其“快速、创新、成本”的核心竞争力得到了充分体现。 1994年,友讯进入中国大陆市场,自主主导D-Link在中国大陆的品牌经营。在广东东莞设有制造工厂,在成都,北京设立了研发中心,并于2002年5月,开始实施将祖国大陆作为“Home Market”的“网络中国,纵横全球”战略。 经过多年的技术积累和市场经营,D-Link的全线网络产品正日益广泛地服务于大陆市场各行业的信息化建设之中。在中小企业、 *** 、电信、教育、金融、网吧等行业,D-Link产品及解决方案正为大陆的信息化建设发挥着积极的推动作用: 在中小企业领域,D-Link凭借卓越的产品品质和出色的技术服务深得广大用户的信赖,成为广大中小企业的首选品牌之一,有效地帮助了中小企业运用网络信息技术提升管理水平、技术创新能力和市场竞争力。 在电子政务领域,D-Link积累了丰富的行业经验,与相关 *** 部门建立了良好的合作关系并饱受好评,主要客户包括国家教委、钓鱼台国宾馆、江苏金税工程、四川省交通局、河南电力系统、北京石景山区 *** 、安阳政协、河南福利彩票发行中心、山西交通厅、中原铝业集团、昆明市公安局等;在金融行业的拓展也初见成效,用户包括国家开发银行、湖南省建行和南京平安保险公司等。 在对产品品质要求严格的电信行业,D-Link专为电信行业用户需求特点量身定做的、具有“定制化”特点的一系列特色整体解决方案在全国电信行业得到了全面认可和成功应用,用户包括中国电信、中国网通、中国铁通和中国移动等运营商。 作为全球第一家推出面向教育系统的“校校通”工程专用产品的厂商,D-Link凭借其在产品品质、技术研发、服务、性价比等方面贯有的优势和“定制化”的产品服务特色,一系列专为教育行业用户量身定做的交换机设备及特色解决方案在全国教育的信息化建设中得到了成功应用,连续三年入围北京市“校校通”工程并已完成北京市500多所中小学校园网。D-Link曾经服务过的项目还包括:国家计委方舟CPU网络工程全国18所重点学校校园网、广州“校校通”工程、西部大学校园网、复旦大学、天津大学、浙江大学、四川大学、河南登封教育城域网、青海教育城域网、天津市中小学信息技术教育的行业信息化配置项目、河南大学、河南师范大学、河南理工大学、河南科技学院、新乡学院、许昌学院、北京科技研修学院、青年政治学院、青岛海洋大学等。 面对蓬勃发展的网吧行业,D-Link全面出击,先后推出了备受网吧青睐的交换机、路由器、KVM、无线网络、视讯、网络安全等在内的多款产品。同时,根据网吧的不同规模及应用特点,D-Link为其量身打造了完善的网络解决方案,为网吧在网络的设计......>> 问题八:东方既白究竟什么来头? 东方既白 东方既白出处 “东方既白”语出苏东坡《前赤壁赋》,“客喜而笑,洗盏更酌,肴核既尽,杯盘狼藉。相与枕藉乎舟中,不知东方之既白”。 东方既白简介 “东方既白”是全球最大的餐饮集团百胜继肯德基、必胜客欢乐餐厅、必胜客宅急送、塔可钟墨西哥风情餐厅之后,在中国推出的第五大餐饮品牌。到2007年12月底为止,“东方既白”在上海已经有12家餐厅了。 东方既白第一家店早在04年5月就在上海大华低调开业。直到8月才有媒体注意到而爆出新闻。对此,百胜的解释是大华东方既白是家试验店,由于中式快餐是前所未有的尝试,百胜特意借此了解市场,完善营运模式,培养团队。在近一年的试验过程中,东方既白听取了大量消费者的要求和反馈,在品种种类、口味、制作方法、厨房和餐厅设计、服务方式等方面作了广泛的研究和改善。 为了保证一战成功,百胜团队在产品开发上下了极大的苦心。设计上首先要求所有不同餐期(早、中、晚餐,点心,小吃,冰点等),甚至儿童专用餐都得有几个硬底子的招牌产品;并且把所有中国人爱吃的包括饭、面、包子、豆浆、酸梅汤都包罗在内;再经过百胜的科学管理,务必保证每一样产品都是市场上质量最好,以及极具特色的东坡焖肉或鱼香肉丝包子。中、午餐一定要试试秘制糖醋小排和原汁鲜茄牛肉面。正餐之间可以尝尝东方既白的美味小吃;香酥翅霸和天椒辣子鸡。小朋友则一定喜欢特别为他们研发的岩烧海苔饭团,造型有趣、营养又好吃,还有玩具赠送。 新一代的东方既白,一改以前中式快餐的经营方式,完全采取肯德基的营运标准。餐厅的装饰风格现代、活泼、轻松。店堂干净清洁,就像走进肯德基一样。服务标准也是比照肯德基,员工活泼亲切。进门就是一字拉开的售卖柜台,上方是一目了然的餐牌,柜台后面是产品保温柜。顾客点餐,付款后食品即买即取,立等可取。 中国百胜餐饮集团旗下备受瞩目的中式快餐品牌东方既白,继05年四月下旬和五月中分别在上海徐家汇美罗城和浦东昌里连续开设两家餐厅后,近日又推出一系列独具特色的中式美食佳品:主食类的“鱼香肉丝饭”;小吃类的“一品芝麻球”;冰品饮料类的“玉米牛奶刨冰”、“冰洛神花茶”等,令其再次聚敛人气,客源大增。东方既白有关负责人指出:为了实现将东方既白打造成最受中国人欢迎的中式快餐品牌的承诺,东方既白自开业以来,一直不断调整并丰富产品的种类,在产品研发上勇于突破,锐意创新,与此同时,在工艺上更注重品质的稳定,确保开发出更多迎合消费者口味,而又能达到现代快餐需求的中式食品。 鱼香肉丝饭 据介绍,东方既白的菜单囊括了大江南北最为中国人普遍接受的品项,主食类代表产品有秘制糖醋小排饭、原汁鲜茄牛肉面、椰香咖喱牛肉饭等。这次推出的“鱼香肉丝饭”,是特别为喜欢川菜的消费者带来的惊喜。在原料选用上,特别下了一番功夫,力求突破传统、推陈出新。该产品除使用优质里脊肉外,特别配上鲜味竹笋、黑木耳,再佐以葱、姜、蒜、辣椒等多种调料精制而成,川辣入味,笋鲜肉嫩。再加上喷香的米饭、精美小菜、鲜蔬和汤,风味超凡,与众不同,是东方既白为满足消费者多种口味需求而推出的一款经典美食。 “一品芝麻球”是东方既白这次开发的小吃类主打产品,无论从口感和营养上,这款产品都达到了“一品” 的要求。该产品选用优质糯米粉和上等芝麻作为原料,经特殊工艺加工而成。据悉,为了将这款产品做出新意,东方既白研发部门进行了大量的摸索和烹调试验。最终的产品是“袖珍版”,这种精巧的设计既容易入口,又方便咀嚼。该产品的另一大特色是馅料的选择:采用营养价值高的黑芝麻,取代传统豆沙馅。整款产品味道独特,表皮酥香,内里韧劲十足,且甜而不腻,营养......>>

时尚双语:使你的网站在周末拥有更多流量的七种简易方法

使你的网站在周末拥有更多流量的七种简易方法 Web traffic for most websites drop during the Weekend because less people are using the inter to look for information or checking their favorite websites for new content. This is a natural and inevitable occurrence and a corresponding dip in traffic figures or sales is nothing to be alarmed about. Jay Wilson recently asked if I had any remendations to stop traffic from reducing during the weekends and as a matter of fact I do have some suggestions that might work although they will require some effort on your part. Getting traffic to your site during the weekends is no different from methods monly used to increase visitors to your site during the weekdays. The key is to focus on hitting defensible traffic sources for referral traffic since these are factors which you can control to a certain extent (as opposed to anic search traffic). Seven Easy Ways to Increase Traffic to Your Site on the Weekend Your goal is to target websites with regular traffic flows and large numbers of users and make them referral sources which will send visitors to your website. Naturally you should try to focus on getting targeted traffic whenever possible. These short-term strategies will allow you to get traffic very soon after you implement them. They will not only reduce your weekend traffic dip but may get you even more traffic to your website than the weekdays. I have omitted other long term traffic building methods like building a munity product development joint ventures or affiliate programs because they are not something you can easily implement for immediate results. 1. Neork within Social Communities. This includes posting and interacting with other people on relevant forums social neorks like Facebook news sites like Digg/Reddit as well as blog sites like Blogcatalog or MyBloglog. There will always been people on crowded online munities and you will always get some visitors if you plug your site discreetly in the right places. 2. Create a Weekend Link Bait. Establish the habit of creating and promoting a weekend Link Bait on popular social websites like Digg Reddit or StumbleUpon. This is by the far the easiest and most powerful way to get traffic to your site during the weekends. Social news sites usually get less news during the weekend and it is likely that your bait will be more successful during this time. 3. Comment on Blogs. While many blogs don"t update during the weekend you can still ment on the ones that do. Focus on those with more traffic and try to be the first few to leave a ment. Make your ment relevant and you"re likely to receive some visitors from others who visit the same blog. 4. Email Pitch Your Website. Write an email to bloggers within your niche to promote your website business or best article for last week. Give away a product or offer premium access for selected publishers in return for a mention. Some blogs like Daily Blog Tips have a habit of doing weekend speed-linking. Pitch your site to these blogs and you"ll get some traffic if you get a link. 5. Try Blog Traffic Exchanges. Blog traffic exchanges are tools which allow you to get traffic by visiting other blogs. They are more useful for newer blogs and as they require more time and effort on your part I suggest using them strategically to find new blogs within your niche as well. 6. Use Paid Advertising. This involves spending money on paid advertising in order to get traffic to your website. Pay per click advertising and social media advertising on sites like StumbleUpon can bring in traffic on the weekends. The benefit of this method is that you don"t have to do any work whatsoever. 7. Publish During the Weekend. Publishing during the weekend will get you some traffic especially if you have many feed subscribers as some of them will visit your site to read the full article or ments. Smaller sites can also benefit as new content will bring in a *** all amount of long tail search traffic. Future publish your post during the weekend so you don"t have to sit down in front of the puter to write. Asking a question is sometimes the quickest way to put out an extra blog post. The downside of all of these methods (with the exception of paid advertising) is the time-investment. Do you really want to spend time in front of the puter on the weekend? The amount of time needed for these tasks will vary and perhaps it would be better to alternate them each weekend to lessen the workload. Another way to deal with this would be to get someone to help promote your site for the weekend instead of doing it yourself. Learning how to oursource marketing is important even for *** webmasters or bloggers because they can really help your website to grow much faster. If you have the time and interest try implementing some of the tactics listed in this article. I"ll love to hear if it helps you to get more visitors this weekend. 由于几乎没有人会在周末利用网络搜索查找信息或者去查看他们感兴趣的网站是否更新,所以每当周末,大多数的网站流量都会有所下降。 这一现象是正常且普遍存在的,所以无论是流量测量及出售者都习以为常。 然而最近Jay Wilson问到了我关于如何防止流量在周末下降的问题,事实上,对此我的确有点见解,不过这可能需要大家付出些努力。 吸引访客在周末浏览你的网站所需要的做的工作总体来说和平时无二,关键在于要将推广重点集中在那些有流量来源保证的站点上以为你自己带来流量,这些流量来源相对于搜索引擎来说其推广广度是可以控制的。 七种为你的网站在周末带来更多流量的方法 你的主要目标是那些有固定流量以及大量用户的网站,以这些网站为中介,为你的站点带来访客。当然,如果可以的话,你应该尽可能以与你相关的网站为目标。 这种短期策略将在你执行后不久便为你带来实际流量。这将不仅仅作用于周末的流量同时也能为你在平常的日子也带去更多流量。 在此,我会略去的一些长期的流量策略如:建立社区、开发产品、参与合作或建立分支等一些你无法立刻看到效果的方法。 1.社会化网络羣体 在一些网站发布文章并和别人互动交流,比如facebook这样的社区论坛或社会化网络站,又比如类似Digg这样的新闻站,当然还有各种各样的博客站。这些站点永远会有大量的在线用户,你只要选对符合你需要的网站参与进去便可以得到源源不断地访问者。 2.建立一个周末链接诱饵(Linkbaiting) 拥有在流行的社会化网站(如Digg Reddit StumbleUpon等)上投放周末链接诱饵的习惯。这是一个使网站在周末拥有流量最容易最有效的方法。 社会新闻网站在周末几乎得不到新闻,在此时投放诱饵往往容易获得成功。 3.评论博客 尽管多数博客在周末不会更新,但是你依然可以评论。对那些流量大的博客做出评论,且尽可能第一个做出评论。作出中肯的评论可以为你带来浏览了同样博客的访客。 4.以Email带动你的网站 写一封宣传你的网站,介绍商务或者推荐最新最好的文章的Email寄给博客主们。放弃一些产品或酬劳以换取其他发布者为你宣传。 有些博客比如Daily Blog Tips就有做周末快速链接的习惯。向这些博客推荐你自己的网站,如果被其链接,你就会得到一些流量。 5.尝试博客流量交换 博客流量交换是一种通过浏览其他博客文章获得流量的方法。这对一些新的博客来说是非常有用的方法,由于这需要花费你的时间和精力,建议对一些新的博文使用该策略。 6.使用付费广告 为你的网站购买付费广告已获得流量。 在StumbleUpon这样网站上购买按点击次数付费广告及社会媒体广告就可以为你的带去周末流量。这么做的好处是,你不用再为推广做任何事。 7.在周末发表文章 在周末发表文章页可以为你带来流量,特别是如果你的网站有很多订阅者,他们中的一些人会去你的网站查看完整文章或作出评论。即使一些小网站也可以因为新文章带来长尾搜索流量从而受益。 预先发布篇在周末公布的文章,你就不一定要做在电脑前写作了。有时候提个问题是最快速保留博文位置的方法。 所有这些方法(除了付费广告外)的共同的坏处是花费时间。你真的想在周末也坐在电脑前花费时间吗?所有这些工作所耗费的时间是无法确定的,或许在每个周末交替着选用其中几个方法会减少工作量。 还有一种方法是请人帮你在周末宣传你的站点,学习一些营销方法是很重要的,因为即使是业余的站长和博主们也能帮助你的网站快速成长。 如果你有时间有兴趣的话,请尝试一下文章中所列的方法。我很希望听到你通过这些方法在周末获得了更多访客和流量的消息。

百度统计和CNZZ到底有哪些不同

从基本的统计数据指标比较:1、CNZZ各个不同的报告提供的指标有一定差异,有针对性,不过比较混乱,体系不够清晰。2、百度统计各个报告的指标设立的较有章法,各个最细的报告上都提供了完整的网站流量和质量评价指标,但有点过于严谨,不过数据也算完整齐全。3、在PV,UV,IP这些基本的统计指标上,百度统计和CNZZ没什么明显差异,而在流量质量评价方面,百度统计采用了基于Session的统计方法,这点是比较科学的。从数据统计的维度比较:1、CNZZ数据维度简单,提供的地区×网络接入商比较实用,但比较难做深入的分析。2、百度统计提供的数据维度非常丰富,特别是时间×来源×地域的组合,可以定位到某一个外链分小时的流量变化,帮助很大,当然,系统上手难一点。从实时网站流量统计比较:1、百度统计的访客访问记录,帮我把用户的访问过程都排列好了,而不像CNZZ是按照IP找,大家都知道一个网吧里出来的都是一个IP,查出来的访问记录那叫一个乱;2、百度统计没有cnzz那个最近15分钟的数据,不过它的最近30分钟的Flash会自动刷新,这点还算方便。从易用性和可用性比较:1、CNZZ要挣钱,肯定得有广告,不过这都还好,关键是偶尔出点问题这一点还是挺让人抓狂的。2、百度毕竟有很多服务器,带宽也大,所以易用性和可用性方面,百度统计胜出。从高级分析和增值功能比较:1、百度是站长无法忽视的重要流量入口,百度统计一旦利用起这一点优势,将非常可怕;2、百度统计的收录量查询、热力图都是非常值得期待的功能;3、广告分析方面,百度统计把来路广告和去向广告都整合了在一起,而CNZZ则分布在好几个系统中,所以百度统计这方面的用户体验较好;4、百度统计子目录的分析非常灵活,CNZZ没有类似功能,这一点我的朋友们反映挺多的;5、CNZZ有短信预警这种功能,这个挺不错的,百度的系统稳定速度快却没有这个功能,还是要好好改进下的。

等离子电视的工作原理(英文或图解)

PDP电视:Plasma Display Panel,简写PDP就是我们平常所说的等离子显示器。 发光原理:等离子显示器是一种利用气体放电的显示装置,这种屏幕采用了等离子管作为发光元件。大量的等离子管排列在一起构成屏幕。每个等离子对应的每个小室内部充有氖氙气体。在等离子管电极间加上高压后,封在两层玻璃之间的等离子管小室中的气体会产生紫外光,从而激励平板显示器上的红绿蓝三基色荧光粉发出可见光。 显著特点: (1) 亮度、高对比度。 (2)纯平面图像无扭曲。 (3)超薄设计、超宽视角。 (4)具有齐全的输入接口,可接驳市面上几乎所有的信号源。 (5)具有良好的防电磁干扰功能。 (6)环保无辐射。 (7)散热性能好,无噪音困优。 优点: 等离子显示器与传统的显像管显示器(就是我们家里现在用的普通模拟电视)相比,优势表现在: ·PDP显示器的体积更小、重量更轻,而且无X射线辐射。 ·由于PDP各个发光单元的结构完全相同,因此不会出现显像管常见的图像的几何变形。 ·PDP屏幕亮度非常均匀——没有亮区的和暗区;而传统显像管的亮度-屏幕中心总是比四周亮度要高一些。 ·PDP不会受磁场的影响,具有更好的环境适应能力。 ·PDP屏幕不存在聚焦的问题。因此,显像管某些区域因聚焦不良或年月已久开始散焦的问题得以解决,不会产生显像管的色彩漂移现象。 ·表面平直使大屏幕边角处的失真和色纯度变化得到彻底改善。高亮度、大视角、全彩色和高对比度,使PDP图像更加清晰,色彩更加鲜艳,效果更加理想,令传统电视叹为观止。 不足 从上面的论述可以看出来,等离子优点非常多,轻薄,这意味着可以满足用户越来越“大”的要求,亮度均匀而且非常明亮(这一点就是LCD液晶电视的缺点),不涉及聚焦问题。但是,最最大的缺点就是--太贵了。不过这是与技术相关的,随着技术的进步,价格就会大幅下降。从支持的厂商来说,国外厂商韩国的LG、三星、现代,我国台湾省的明基、中华映管等,美国的Plasmaco公司、荷兰的飞利浦公司和法国的汤姆逊公司等都开发了各自的PDP产品。我国的TCL、创维、海信都推出了自己的产品。就我个人来说,作为将来家庭电视影院化,PDP是首选,当然前提是期待价格速降

第一性原理

第一性原理如下:根据原子核和电子相互作用的原理及其基本运动规律,运用量子力学原理,从具体要求出发,经过一些近似处理后直接求解薛定谔方程的算法,习惯上称为第一性原理。资料扩展:第一性原理通常是跟计算联系在一起的,是指在进行计算的时候除了告诉程序你所使用的原子和他们的位置外,没有其它的实验的,经验的或者半经验的参量,且具有很好的移植性。作为评价事物的依据,第一性原理和经验参数是两个极端。第一性原理是某些硬性规定或推演得出的结论,而经验参数则是通过大量实例得出的规律性的数据,这些数据可以来自第一性原理(称为理论统计数据),也可以来自实验(称为实验统计数据)。但是就某个特定的问题,第一性原理和经验参数没有明显的界限,必须特别界定。如果某些原理或数据来源于第一性原理,但推演过程中加入了一些假设(这些假设当然是很有说服力的),那么这些原理或数据就称为“半经验的”。第一性原理,英文First Principle,是一个计算物理或计算化学专业名词,广义的第一性原理计算指的是一切基于量子力学原理的计算。我们知道物质由分子组成,分子由原子组成,原子由原子核和电子组成。量子力学计算就是根据原子核和电子的相互作用原理去计算分子结构和分子能量(或离子),然后就能计算物质的各种性质。从头算(ab initio)是狭义的第一性原理计算,它是指不使用经验参数,只用电子质量,光速,质子中子质量等少数实验数据去做量子计算。但是这个计算很慢,所以就加入一些经验参数,可以大大加快计算速度,当然也会不可避免的牺牲计算结果精度。
