As we announced earlier this month at the annual Adobe Max Conference, DMXzone has been working on extension that provides complete support for Twitter Bootstrap in Dreamweaver. With the DMXzone Bootstrap you'll have a crafty tool in your hands to edit your layouts fully visual in DW design view and experience the great bootstrap power with its responsive grid. This and many more comes on DMXzone next week so stay tuned.

The Web Application Security Working Group has published a Working Draft of User Interface Security Directives for Content Security Policy. This document defines directives for the Content Security Policy mechanism to declare a set of input protections for a web resource's user interface, defines a non-normative set of heuristics for Web user agents to implement these input protections, and a reporting mechanism for when they are triggered. Learn more about the Security Activity.

The Device APIs Working Group and the Web Applications (WebApps) Working Group have published Working Group Note of Web Intents. This informative specification defines a service discovery and light-weight RPC mechanism for web apps called Web Intents. This document defines DOM interfaces and markup used by client and service pages to create, receive, and reply to Web Intents messages, and the procedures the User Agent carries out to facilitate that process. Learn more about the Ubiquitous Web Applications Activity.

The Device APIs Working Group has published a Last Call Working Draft of Vibration API. This specification defines an API that provides access to the vibration mechanism of the hosting device. Vibration is a form of tactile feedback. Comments are welcome through 13 June. Learn more about the Ubiquitous Web Applications Activity.

Distributed transactions are costly because they use agreement protocols. Calvin says, surprisingly, that using a deterministic database allows you to avoid the use of agreement protocols. The approach is to use a deterministic transaction layer that does all the hard work before acquiring locks and the beginning of transaction execution. Overview: Many distributed storage systems achieve high data access throughput via partitioning and replication, each system with its own advantages and tradeoffs. In order to achieve high scalability, however, today’s systems generally reduce transactional support, disallowing single transactions from spanning multiple partitions. Calvin is a practical transaction scheduling and data replication layer that uses a deterministic ordering guarantee to signi?cantly reduce the normally prohibitive contention costs associated with distributed transactions. Unlike previous deterministic database system prototypes, Calvin supports disk-based storage, scales near-linearly on a cluster of commodity machines, and has no single point of failure. By replicating transaction inputs rather than effects, Calvin is also able to support multiple consistency levels—including Paxos based strong consistency across geographically distant replicas—at no cost to transactional throughput. If you are interested Daniel Abadi gives a very accessible overview of Calvin in If all these new DBMS technologies are so scalable, why are Oracle and DB2 still on top of TPC-C? A roadmap to end their dominance.

The User Agent Accessibility Guidelines Working Group has published two Working Drafts today. User Agent Accessibility Guidelines (UAAG) 2.0. UAAG 2.0 provides guidelines for designing user agents that lower barriers to Web accessibility for people with disabilities. User agents include browsers and other types of software that retrieve and render Web content. A user agent that conforms to these guidelines will promote accessibility through its own user interface and through other internal facilities, including its ability to communicate with other technologies (especially assistive technologies). Furthermore, all users, not just users with disabilities, should find conforming user agents to be more usable. Implementing UAAG 2.0. This document provides supporting information for the User Agent Accessibility Guidelines (UAAG) 2.0 for designing user agents that lower barriers to Web accessibility for people with disabilities. In addition to helping developers of browsers and media players, this document will also benefit developers of assistive technologies because it explains what types of information and control an assistive technology may expect from a conforming user agent.

We received so much feedback about our last week's Creative Studio showcase that we decided to turned it into a Dreamweaver template and today, it's available for free download in our Templates section. If you missed this stunning page, below you will find the showcase and a video tutorial how it's been created. Note that you need to have the HTML5 Parallax Slider and DMXzone Nivo Slider installed in order to be able to install and edit/customize the template in Dreamweaver.

Google is enabling a more naturally spoken question-and-answer interface to its search service for people with a new version of Chrome. Google demonstrated conversational search at Google I/O a week ago, a style of search designed to be more like natural human speech than the technically constructed search queries that people often use today to retrieve information from a search engine.
