Thoughts on Opera Unite | FactoryCity: "Okay, so I shit all over Opera Unite, but you can’t come out and promise all kinds of world-changing, freedom-enhancing goodness and then not deliver! — worse, to do so when their newest competitor (Google!) is schooling everyone with the perfect example of how to do it right (see: Wave)."

An introduction to Opera Unite - Opera Developer Community

An introduction to Opera Unite - Opera Developer Community

The time has come to raise the curtain on yet another exciting new Opera technology release. The drums are playing a low roll, which increases in intensity as the onlookers stare in antici … pation; the lights begin to come up, along with the curtain; the stage is all set for passion and the energy of today’s performance; the narrator spoils the mood by talking through it (that’s me…)

So what is Opera Unite? In a nutshell, Opera Unite is a collaborative technology that uses a compact server inside the Opera desktop browser to share data and services. You can write applications — in the form ofOpera Unite Services — that use this server to serve content to other Web users.

Why is this exciting? Well, it allows you to interact with contacts, sharing data and services without the need for any third-party Web sites/applications to be involved at all. Think of the possibilities:

• You could play games and chat to your peers directly using the service
• You could share photos and videos with peers, straight off your hard drive, without needing to use third-party Web applications
• You can work collaboratively with others on files such as data and images (think wikis or drawing applications), and then work with those files offline if you wish, before sharing them again at a later date
• You could even start creating some crazy hacks, like an application that controls a remote car across the Web (I’ve seen a rough prototype in action)

Itching to know more? Good. In this article I first present a tour of Opera Unite, with details of how to activate it, how to install a Opera Unite service, and how to use those services to collaborate with your friends and colleagues. If you want to find out more about developing your own Opera Unite Services, read our Opera Unite developer's primer.

How to please the customer: "We have a tendency to focus on the easy comparisons and ignore those that may be more important but are harder.

Knowing this, salespeople often present us with a chain of carefully selected pairs of easy choices that lead us to the position they want to get us to."

URI Template

URI Template: Joe Gregorio from Google: "A URI Template is a compact sequence of characters used for the construction of URIs. This specification defines the URI Template syntax and the process for expanding a URI Template into a URI, along with guidelines and security considerations for the use of URI Templates on the Internet. The URI Template syntax allows for the construction of strings that are a superset of URIs, allowing an implementation to process any URI Template without knowing the scheme-specific requirements of every possible resulting URI."

Asa Dotzler: Firefox and more: one year of internet explorer usage share

Asa Dotzler: Firefox and more: one year of internet explorer usage share

Internet Explorer 6 continues its long downward trend, dropping about 10 points in the last year and IE 8 has been cannibalizing IE 7 users at a strong pace for the last 3 months.

I expect that the next month will see IE 6 finally fall under 15% (and hopefully trending to fall under 10% by the end of this year.) That's good news for everyone.

We should also see IE 8 meeting IE 7 and crossing at about 25% each in the next couple of months.

HTML 5 and Web video: freeing rich media from plugin prison - Ars Technica: "DailyMotion and Google are both experimenting with the HTML 5 video element and have strongly endorsed standards-based solutions for deploying video on the Web. Ars takes a close look at the state of open video and explores both the benefits and challenges of liberating rich media from the proprietary plugin prison."

Google Wave as infrastructure

Google Wave as infrastructure: "All of the things in the Wave demo are possible without Wave. The interesting thing about Wave is not so much the application, but the infrastructure, the protocol and the underlying concepts. Many limited collaboration apps have offered various subsets of the Wave functionality, for example, and the superficial functionality can be built using existing technology, without fancy new protocols and clients etc.

But that's missing the point. Wave is interesting because the infrastructure makes it extremely open-ended.

A lot of people have been comparing Wave to e-mail. That's missing the point too. Wave has the potential to be as important as the Web. I'm serious. Wave is taking the web and making it interactive, embeddable, recordable, and shareable on a whole different level than what we are used to. And like most great 'revolutionary' ideas it doesn't actually add all that much new"

Google Bets Big on HTML 5: News from Google I/O - O'Reilly Radar

Google Bets Big on HTML 5: News from Google I/O - O'Reilly Radar: "'Never underestimate the web,' says Google VP of Engineering Vic Gundotra in his keynote at Google I/O this morning. He goes on to tell the story of a meeting he remembers when he was VP of Platform Evangelism at Microsoft five years ago. 'We believed that web apps would never rival desktop apps. There was this small company called �Keyhole, which made this most fantastic geo-visualization software for Windows. This was the kind of software we always used to prove to ourselves that there were things that could never be done on the web.' A few months later, Google acquired Keyhole, and shortly thereafter released Google Maps with satellite view.
'We knew then that the web had won,' he said. 'What was once thought impossible is now commonplace.'
Google doesn't want to repeat that mistake, and as a result, he said, 'we're betting big on HTML 5.'"

Google Wave Preview

Google Wave PreviewThis presentation is an hour and 20 minutes but an interesting view into collaborative systems. Google are positioning this as the future of email while merging with tools like Google Docs. A chain of emails is a conversation, which in Wave is a type of document, somewhat like a Wiki or a bulletin board. In essence it is a server hosted document tree collaboratively edited. Changes are made real-time like Google Talk (pushed through via Jabber-like XMPP)

Draft Protocol Spec ‎(Google Wave Federation Protocol)‎

Draft Protocol Spec ‎(Google Wave Federation Protocol)‎: 

Google Wave is built on top of XMPP which is the core protocol of the Jabber Instant Messaging.

"Waves are a new medium for communication that could be described as a new form of multi-user document. Conceptually, waves do not exist themselves, instead being made up of a set of one or more wavelets which in turn contain one or more documents. A wave is visualised to participants primarily through display of its root conversation wavelet, which is discovered through convention (wavelet of ID '~conversation/root'). Users become notified of wavelets by being added as participants, ala being invited to edit and participate in a multi-user document. It is also worth noting that wavelets have create-on-use semantics, and as such, users must create a new wave by adding themselves to its (currently non-existant) root wavelet."

Google Wave Drips With Ambition. A New Communication Platform For A New Web.

Yesterday, during the Google I/O keynote, Google’s VP of Engineering, Vic Gundotra, laid out a grand vision for the direction Google sees the web heading towards with the move to the HTML 5 standard. While we’re not there yet, all the major browser players besides Microsoft are aligned and ready for the next phase, which will include such things as the ability to run 3D games and movies in the browser without additional plug-ins. But Google wants to take it one step further with a brand new method of communication for this new era. It’s called Google Wave.

John Resig - ECMAScript 5 Strict Mode, JSON, and More

John Resig - ECMAScript 5 Strict Mode, JSON, and More: "Altogether I think ECMAScript 5 makes for an interesting package. It isn't the massive leap that ECMAScript 4 promised but it is a series of respectable improvements that reduces the number of obvious bugs while making the language safer and faster. I'm looking forward to when some implementations start to go public."

Sarissa - Sarissa Home Page: "Sarissa is an ECMAScript library acting as a cross-browser wrapper for native XML APIs. It offers various XML related goodies like Document instantiation, XML loading from URLs or strings, XSLT transformations, XPath queries etc and comes especially handy for people doing what is lately known as 'AJAX' development."

John Resig - ECMAScript 5 Objects and Properties

John Resig - ECMAScript 5 Objects and Properties: "ECMAScript 5 is on its way. Rising from the ashes of ECMAScript 4, which got scaled way back and became ECMAScript 3.1, which was then re-named ECMAScript 5 (more details)- comes a new layer of functionality built on top of our lovable ECMAScript 3.

There are a few new APIs included in the specification but the most interesting functionality comes into play in the Object/Property code. This new code gives you the ability to dramatically affect how users will be able to interact with your objects, allowing you to provide getters and setters, prevent enumeration, manipulation, or deletion, and even prevent the addition of new properties. In short: You will be able to replicate and expand upon the existing JavaScript-based APIs (such as the DOM) using nothing but JavaScript itself."

Ajaxian � Digg shows Multipart XMLHttpRequest prototype

Ajaxian � Digg shows Multipart XMLHttpRequest prototype: "One of the ways that high-performance websites like Yahoo suggest speeding up load times is by reducing the number of HTTP requests per page. We started thinking about what we could do to reduce HTTP overhead, and where we could get the biggest benefits from it. Well, one thing led to another and the next thing we knew we were talking about writing a generalized framework for bundling files, sending them through a single request, then separating them for use once they head down the pipe."

ongoing � Database Helper: Tim Bray: "I’ve been in a lot of Cloud-flavored discussions recently about what kind of Platform-as-a-Service offerings might hit sweet spots. On several occasions, People Who Should Know have said things like “A huge proportion of apps, even really big apps, can coast along just fine on a single MySQL instance with help frommemcached.” Some numbers crossed my radar today that would tend to support that theory; and they’re sort of astounding.

Check out Zoran Radovic’s Scaling Memcached: 500,000+ Operations/Second with a Single-Socket UltraSPARC T2. The title kind of says it: hundreds of thousands of ops per second, and a saturated 10G Ethernet link, with a 1U single-socket server. Now, benchmarks aren’t reality, but them are still some mind-boggling numbers.

Our Shanti Subramanyam has been mining the same territory with the new Nehalem boxes; see Memcached Performance on Sun's Nehalem System and Multi-instance memcached performance. And there were some even scarier numbers being bandied about on an internal email list; stay tuned.

But still, at the end of the day, that throughput on a single-socket box is the real news story, to my eye."

The Dam Just Broke: Facebook Opens Up to OpenID - ReadWriteWeb

The Dam Just Broke: Facebook Opens Up to OpenID - ReadWriteWeb

In a few minutes Facebook will become the biggest example of a social network that allows users to log-in with OpenID credentials granted to them by other companies' websites. Major networks have said for months that their ID could be used as OpenID, but becoming "relying parties" that accepted OpenID from elsewhere was the step everyone was waiting for. The dam has broken.

It's ironic that it's Facebook that did it. Facebook is probably the most closed of all the major social networks (other than LinkedIn) and is so far ahead of everyone else in market share that traditional logic would argue that they have no interest in this kind of interoperability. This is the kind of step that was expected from networks more open and, frankly, far behind Facebook. Nevertheless, it has happened and it's big news.

New Facebook users will now be able to create Facebook accounts using their Gmail credentials and existing users will be able to associate and thus log in with Gmail or any other OpenID account that supports "automatic login."

Time and Space Tradeoffs in Version Control Storage

Time and Space Tradeoffs in Version Control Storage: "Storage is one of the most difficult challenges for a version control system.� For every file, we must store every version that has ever existed.� The logical size of a version control repository never shrinks.� It just keeps growing and growing, and every old version needs to remain available.

So, what is the best way to store every version of everything?"
