Google has announced Eddystone, an open-source Bluetooth LE beacon format for developers to integrate into cross-platform applications.Eddystone defines a Bluetooth low energy (BLE) message format for proximity beacon messages, supporting multiple frame types for various application use cases on Android, iOS or other mobile platforms. Google is launching two new APIs along with Eddystone—the Nearby API and the Proximity Beacon API—allowing developers to enable beacon-based communication between devices in close proximity, and to associate semantic locations with beacons.Google engineer Chandu Thota and product manager Matthew Kulick detailed Eddystone and additional developer features of the format in a blog post.“By design, a beacon is meant to be discoverable by any nearby Bluetooth Smart device via its identifier, which is a public signal,” they stated. “At the same time, privacy and security are really important, so we built in a feature called Ephemeral Identifiers (EIDs) which change frequently, and allow only authorized clients to decode them. EIDs will enable you to securely do things like find your luggage once you get off the plane or find your lost keys. We’ll publish the technical specs of this design soon.”Salesforce launches Salesforce ShieldSalesforce has unveiled Salesforce Shield, a set of cloud application development services that expands the security and compliance toolsets of developers creating apps on the Salesforce1 platform for regulated industries. Built natively into the Salesforce1 Platform, Salesforce Shield is made up of three core services: event monitoring, field audit trail and platform encryption. These services bring drag-and-drop tooling functionality to building auditing, encryption, archiving and monitoring capabilities natively into Salesforce1 apps.More details are available in the Salesforce blog post.Glimpse joins Microsoft’s Visual Studio teamGlimpse, the startup behind the open-source Web debugging and diagnostics tool for ASP.NET, is joining Microsoft on the Visual Studio team.Glimpse is used by ASP.NET developers to provide an intuitive visual timeline of request execution, a log of SQL queries, a URL route debugger, and more embedded directly into the Web page.
