Engaging in-depth on the web with peer-to-peer connections.
As the web platform continues to evolve, tools have emerged for connecting people and computers in new and interesting ways. Web Real-Time Communication (WebRTC) stands out as one of the most significant and disruptive of these emerging technologies, allowing developers to embed peer-to-peer real-time communication in the browser without proprietary plugins, while breaking away from the traditional client-server paradigm.
Since Google released and open-sourced the WebRTC project in early 2011, the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C) have been working together to formalize the WebRTC standard and 1.0 stable release. Companies like Twilio and Vidyo have adopted WebRTC as a protocol for video chat in the browser, and established telco and VoIP players such as Cisco, Ericsson, and Telefónica have also lent support to the project.
At the most recent meeting of the IETF, Simon Pietro Romano, author of Real-Time Communication with WebRTC, hosted a panel to discuss developments in the WebRTC community and the road ahead. The panel, who are driving forces behind ongoing standardization and implementation, included:
- Justin Uberti, tech lead for the WebRTC team at Google
- Eric Rescorla of Mozilla
- Dan Burnett, editor of the PeerConnection and getUserMedia W3C WEBRTC specification
- Cullen Jennings, Cisco Fellow and Co-Chair of the IETF RTCWeb
I’d encourage you to listen to the whole conversation, but to get started, you might explore these highlights.
In this O'Reilly Radar Podcast: Simon St. Laurent discusses the web's potential, and Tom Greever chats about experience design.
Simon St. Laurent, O’Reilly’s strategic content director for our web space and co-chair of our Fluent Conference, recently launched an investigation looking into the web’s potential to change not only computing, but the world in general. For this podcast episode, I caught up with St. Laurent to talk about the timing, what he’s exploring, and why the web isn’t dead. He said that in some ways, it has always been the right time to launch this investigation — after all, the web has continued to grow amidst market crashes and the dot-com bust — but noted the driving factors behind the health of the web are becoming more clear:
Exploring open web crawl data — what if you had your own copy of the entire web, and you could do with it whatever you want?
For the last few millennia, libraries have been the custodians of human knowledge. By collecting books, and making them findable and accessible, they have done an incredible service to humanity. Our modern society, culture, science, and technology are all founded upon ideas that were transmitted through books and libraries.
Then the web came along, and allowed us to also publish all the stuff that wasn’t good enough to put in books, and do it all much faster and cheaper. Although the average quality of material you find on the web is quite poor, there are some pockets of excellence, and in aggregate, the sum of all web content is probably even more amazing than all libraries put together.
Google (and a few brave contenders like Bing, Baidu, DuckDuckGo and Blekko) have kindly indexed it all for us, acting as the web’s librarians. Without search engines, it would be terribly difficult to actually find anything, so hats off to them. However, what comes next, after search engines? It seems unlikely that search engines are the last thing we’re going to do with the web. Read more…
Plugin-free vector graphics are now easier than ever before
Thirteen years ago, in 2001, the World Wide Web Consortium (W3C) finalized the specification for Scalable Vector Graphics, version 1.0. A few months later, in early 2002, O’Reilly published the original SVG Essentials, describing both the basics and the wonderful potential of SVG. An open standard for vector graphics, with support for scripting and animation, was an area of boundless possibility.
From some perspectives, not much has changed. The official SVG specification is still at version 1.1, which was released in 2003 and edited in 2011. Neither update introduced new features to SVG, instead focusing on improving clarity and consistency in the details.
In practice, however, SVG has changed considerably. There are numerous tools for creating SVG, both full-featured graphics programs and online widgets. Most importantly, nearly every web browser out there treats SVG as a first-class citizen (some outdated mobile and Internet Explorer versions being exceptions), displaying SVG as an interactive part of your document with no need for plug-ins.
In search of the holy grail, again
When I started at @WalmartLabs I was placed on team that was tasked with creating a new web framework from scratch that could power large public facing web sites.
