Opera Unite 掀起网络应用新革命
2009年06月16日15:31
来源:搜狐IT
2009年6月16日,浏览器厂商Opera软件公司发布了一项革命性的网络技术:
Opera Unite。它将彻底颠覆互联网传统的“客户端-服务器”计算模式。有了Opera
Unite,每一台电脑都可以既成为客户端也成为服务器,从此电脑之间可以直接通
过网络进行点对点互动和信息共享,再也不需要通过第三方服务器中转。
Opera Unite使得传输数据就像浏览网络般轻松简单。对于消费者而言,使用
Opera Unite技术可保证用户对数据资料拥有更强的控制权,并可轻松实现与任何
安装有现代网络浏览器的设备联网共享信息。
对于网络开发人员而言,由于Opera Unite应用服务基于与日常网站开发所遵
循的一样的开放式网络标准,创建开发网络应用的难度就极大地降低了。有了
Opera Unite,创建一个完全的网络应用跟编写一个普通网页一样简单。
使用Opera Unite步骤:
1. 到http://labs.opera.com/ 下载并安装含有Opera Unite的Opera 10 beta
浏览器特别版本;
2. 安装完毕启动Opera浏览器后,点击浏览器左下角Opera Unite图标,然后
用你已有的Opera ID登录,即可启动Opera Unite。该Opera ID就是你登录My
Opera社区或者使用Opera Link(浏览信息同步)的账号;如无,你也可即时注册
一个。
3. 现在你可以享用美妙的Opera Unite了。打开浏览器左侧的Opera Unite面
板,尽情享受各种Opera Unite应用服务吧。你还可以到http://Unite.opera.com/
去下载安装更多的服务。
4. 当启动一个服务后,你会得到一个指向运行在本设备上的该服务的网址。
例如,如果你在你的笔记本电脑上启动了“照片共享”服务,你会得到这个网址:
http://notebook.username.operaunite.com/photo_sharing/ 。这里,
“notebook”是你的设备名(由你自己定义),“username”是你的用户名,
“photo_sharing”是你启动的Opera Unite服务名。你的朋友只需在他们自己电脑里
的浏览器里输入这个网址,就能联机使用你的这项服务了。
目前Opera Unite已开通的应用服务有:
文件共享(File Sharing):与好友安全地分享文件而无需上传。你需要做
的就是选定你希望分享的文件所在的文件夹,Opera Unite将自动生成一个网址直
接指向该文件夹。将该网址发送给你的朋友,你就可与他轻松共享文件而不需调用
任何第三方网络服务。
网络服务器(Web Server):在自己的PC上直接创建并运行一个网站。选定
包含有你创建的网站所有网页的文件夹,Opera Unite能自动识别index文件并按照
你的设计生成一个网站。把网址发布出去,只要你开着机联着网,网友们就都可以
顺畅访问你独家发布的网站!
媒体播放器(Media Player):不管身在何方,随意聆听电脑里的好歌。在
选定分享歌曲所在文件夹后,你和你的好友可在联网的设备里使用任何浏览器登录
由Opera Unite生成的网址直接听歌。
照片共享(Photo Sharing):无需上传,直接与好友远程分享电脑里的照
片。选定照片文件夹后,Opera Unite将创建照片缩略图并生成一个网址。你的好
友只需在任何浏览器里输入该网址,就可点击缩略图从而欣赏完整尺寸的照片。
休息厅(The Lounge):你自己的网上聊天室,任意与好友私聊。你的好友
不需使用任何别的服务就能通过Opera Unite生成的网址在浏览器里进入并参与聊
天。当然,发起方可以创建进入聊天室的密码进行准入管理。
冰箱门(The Fridge):虚拟的冰箱门,可随意贴条留言。把这个服务网址
发给你的好友后,他们就可以在你的冰箱门上实时留言和交流了。
以上这六个服务只是一切可能性的开始。网络开发者们可以充分发挥创造力开
发各种网络应用,Opera Unite的潜力是无限的。

“今天,我们为所有人开启了通往网络全部潜力的大门,”Opera软件公司全球
首席执行官谭咏文(Jon S. von Tetzchner)表示,“技术的发展往往是周期性
的。若干年前,个人电脑的出现把计算从大型计算机主机中分散开来。现在,
Opera Unite则将计算从云上分散开来,进一步发挥用户的能动性。当浏览器拥有
了服务器功能,网络开发者们就可以更轻松地开发网络应用;而用户也拥有了选择
更安全和有效的信息共享方式的自由。我们相信,Opera Unite将是迄今为止Opera
最重大的创新之一;因为它将彻底颠覆网络的基本架构。”
“Opera Unite让我最感兴趣的是:现有技术和社会世界是如何相互关联的,”
Opera网络推广专家Molly E. Holzschlag女士说,“只需使用一些包括HTML、CSS和
JavaScript等在内的公开的网络标准,网络开发人员甚至是略懂网络标准的网络爱
好者就能开发出他们自己的Opera Unite应用服务。Opera Unite赋予了人们通过技
术去实现想象力的能力,人们能够创建广泛的技术应用和社交服务;而这一切都只
需使用已有的、公开的网络标准。”

My name is Lawrence Eng, and, as a product analyst for Opera Software, my job is to understand our users and what they need, so we can serve them better. Today, I will share my thoughts on Opera Unite, a new Opera technology that I’m extremely excited about. I’ve been an avid Opera user since 2001 and have seen the numerous innovations Opera has introduced to dramatically improve the experience of Web browsing. Of all the new features we’ve introduced over the years, none of them have filled me with as much anticipation as Opera Unite. This technology is a radical first step towards addressing what I call “the Internet’s unfulfilled promise”, which is about our ability to connect with each other and participate meaningfully online—on our own terms, and without losing control of our data.
In this article I will explain what Opera Unite is, discuss “the Internet’s unfulfilled promise” in more detail (and explain how it led to us creating Opera Unite), and share some inspirational ideas to illustrate what you can do with it.
If you haven’t already, download the new Opera Unite alpha builds available, and start playing:
Let us know what you think!
Opera Unite is a unique technology that turns any computer or device running Opera into a Web server. In other words, your computer (running Opera Unite) is truly part of the fabric of the Web, rather than just interacting with it, and it’s something anyone can use. With Opera Unite, everyday non-technical users can serve and share content and services directly from their own computers in the form of intuitive applications. That sounds kind of cool from a technology point of view, but what can you do with it, and why is it important?
With Opera Unite, we are giving developers a chance to develop applications (known as Opera Unite services) that directly link people’s personal computers together, so that you can connect with one or more of your friends at the same time. It all happens through the browser, so no additional software has to be downloaded, and it will work wherever Opera works (Windows, Mac, Linux, and later mobile phones and other devices). Opera provides the platform and you provide the applications—what you create is limited only by your imagination. We believe Opera Unite will redefine what’s possible with Web applications, and we invite you to join us in moving beyond stale ideas and limitations.
What will Opera Unite services look like? How will they be different from other application platforms out there, and what will users be doing with Opera Unite that they weren’t doing before, using other technologies?
The initial applications offered by Opera Unite are just simple demos (such as a “messenger” application and a media player) that replicate existing services and online functionality, showing them working in the context of Opera Unite. That’s just the tiniest tip of the iceberg—the potential for what can be done is much larger. The key to Opera Unite is that it enables a whole new class of social software on the Web, applications that benefit from two or more people being online at the same time. And, with Opera Unite, these people can all connect directly without needing middlemen who control third-party servers.
What Opera Unite offers is an opportunity and a challenge to developers and entrepreneurs who are creative enough to envision new ways that people can interact online, so that computing becomes truly interpersonal.
At this point, if you’re already convinced about Opera Unite’s potential, feel free to jump to part 3 for some examples of what Opera Unite services might look like in the near future. If you want to learn more about whywe created this technology, read the next part.
Originally the Internet’s promise was that it would connect us all, bringing people together in a whole new way, bypassing the constraints of geography. The Web meant that we could all be part of a larger human network. How we actually interact with each other online, however, has been shaped by particular techno-social circumstances. Because of those circumstances, our online interactions have been constrained and are far from perfect.
Undoubtedly, the ability to participate online has increased, especially for people in developed countries. Self-publishing, self-expression, and social networking retain their status as the cornerstone of online activity for millions of people around the world. That said, people who create and share content will never approach true empowerment online until the computers they use are actually part of the Internet. Currently, most of us contribute content to the Web (for example by putting our personal information on social networking sites, uploading photos to Flickr, or maybe publishing blog posts), but we don’t contribute to its fabric — the underlying infrastructure that defines the online landscape that we inhabit.
Our computers are only dumb terminals connected to other computers (meaning servers) owned by other people — such as large corporations — who we depend upon to host our words, thoughts, and images. We depend on them to do it well and with our best interests at heart. We place our trust in these third parties, and we hope for the best, but as long as our own computers are not first class citizens on the Web, we are merely tenants, and hosting companies are the landlords of the Internet.
Social networking is important, but who owns it — the online real estate and all the content we share on it? How much control over our words, photos, and identities are we giving up by using someone else’s site for our personal information? How dependent have we become? I imagine that many of us would lose most of our personal contacts if our favorite Web mail services shut down without warning. Also, many of us maintain extensive friend networks on sites like MySpace and Facebook, and are, therefore, subject to their corporate decisions via “Terms of Service” and click-through agreements. Furthermore, what does it mean anyway to be connected to hundreds of our “closest” friends? What about our real social networks, the people we want to interact with on a regular basis (like once a week, or even every day)? Why are online solutions to help us with our real-world social needs so few and far between?
We are connected to a Web that has democratized much and is an amazing source of information. However, “the wisdom of the crowd,” along with the notion that our data ought to live on other people’s computers that we don’t control, has contributed to making the Internet more impersonal, anonymous, fragmented, and more about “the aggregate” than the individual. In fact, quite the opposite of the original promise. For too long, we’ve been going online to connect to each other, but sacrificing intimacy as a result.
With Opera Unite, I think we can start moving in a different direction. I hope you’ll join me in imagining a more personal and social computing experience that actually begins to deliver on the old (but not forgotten) promise of the Internet bringing people together in meaningful ways.
The first few services we’ve released for Opera Unite are fairly simple and offer functionality that you’ve likely seen elsewhere, perhaps on desktop applications or 3rd party web sites. These first few demos are meant to illustrate how Opera Unite services are put together and the basics behind the new technology. Building on that foundation, what power will developers unlock when they create and deploy Unite Services in the future? Below is an illustration of what an Opera Unite service could look like. In coming weeks, we’ll follow this up with further ideas and concepts.
At Opera, when we first talked about media applications created for Opera Unite, one idea was a simple music player, where I would play a song on my computer, and my friends on their computers would then hear the same song on their machines. That’s not a bad idea, but is it something people would truly want to use? Does it offer anything revolutionary or anything fun, like a social component, that makes it worthwhile to use?
In trying to come up with something better, I envisioned the Opera Unite Jukebox application. Instead of just choosing a song and forcing all of my online friends to hear it, the Opera Unite Jukebox will let me choose 10 songs from my collection and put it in the queue, and all 8 of my friends who are connected to me (via Opera Unite) will do the same. In doing so, we create a virtual jukebox that contains the songs we’ve all selected. The jukebox will then play the songs to all of us (in random order), creating a shared listening experience. It’s sort of like online radio but with a social component, harking back to the days of going to a friend’s house to listen to records/tapes/CDs together. It’d be great for get-togethers too, allowing everyone to be the party DJ.
Additional application features might include:
The Opera Unite Jukebox is just one simple example. Opera Unite services can be just about anything. It’s up to developers, companies, entrepreneurs, end users, and anyone with a vision of what the interpersonal Web really means, to take that vision and build the next generation of applications that bring people together online in brand new ways.
Think of multiplayer games, from simple two-player challenges like Chess up to sprawling RPGs. And Opera Unite is not just about fun. Think about collaborative applications such as spreadsheets, documents or Wikis, which you can work on with friends and colleagues without having to host them on a third-party site such as Google Spreadsheets or installing specialized applications on a dedicated server. You could use reverse Ajax or “COMET” techniques to mean that all the updates are seen on everyone’s computers in real time; multiple people could make changes at once, without having to lock people out.
Opera Unite applications can be just about anything. It’s up to developers, companies, entrepreneurs, end users, and anyone with a vision of what the interpersonal Web really means, to take that vision and build the next generation of applications to bring people together online in brand new ways.
In upcoming installments of this series, we will discuss other uses we envision for Opera Unite services.
