Methods and apparatus to provide extended object notation data are disclosed. An example apparatus includes a data handler having a first input to receive object data and a first output to output an object notation key-value pair for the object data; a string processor having a second input coupled to the first output and a second output to convey the object notation key-value pair without string literals; and a hashing and encryption handler having a third input coupled to the second output and a third output to convey the key-value pair signed with a private key, to convey the key-value pair encrypted with a public key, and to convey an indication that the encrypted key-value pair is encrypted in a key of the encrypted key-value pair.

Techniques and configurations for streaming metadata between devices are disclosed herein. In one example embodiment, streaming textual data, for example subtitles or closed caption data, are provided from a consumer television or set top box (STB) platform to a tablet computer platform. XMPP and BOSH are used as infrastructural components to help establish the client/server connection between the platforms. These components also maintain this connection and support real-time communications and transfer of data between the platforms. In an example embodiment, an application on the primary platform has a string of metadata which is communicated to a client application on a second platform. For example, client application may be a smart phone app in the form of an HTML5 app running on browser. The system may stream and control bi-directionally. In this architecture an XMPP-implementing JavaScript library allows XMPP client interaction through an XML stanza.

In one example of the present disclosure, a method for establishing communication between a browser and a native application is disclosed. The method may be initiated by executing a browser extension associated with the browser. The method may execute a native host to initiate startup of the native application. The native host may interface with the native application to establish bidirectional communication between the native host and the native application. The native host may also interface with the browser extension to establish bidirectional communication between the native host and the browser extension to connect the browser and the native application.

A method is disclosed for exposing virtual disk images on a user device, which is running an HTML5 KVM virtual media client in a Web browser, and which has established a KVM session with a KVM device associated with a remote device. A selected disk image file is initially obtained by the user device and a message sent to the remote device that the disk image file is available for use. The HTML5 KVM virtual media client exposes the disk image file for use to the remote device, which sends a message to the HTML5 KVM virtual media client requesting a specific portion of the disk image file. The HTML5 KVM virtual media client receives the message and a script engine running in the Web browser creates a new file available to the Web browser of just the portion requested by the remote device, which is then transmitted to the remote device.

Certain example embodiments relate to web applications. In certain example embodiments, an instance of a web application is executed using a client device. In response to the instance being started up, metadata is retrieved using a service embedded in the application and invoked at a bootstrap hook. The metadata is associated with earmarked programmatic elements in the application. At the client device and using an evaluation service injected into operation of the instance, one or more configured rules are evaluated against input. The rules are definable in relation to the earmarked programmatic elements using the retrieved metadata. They specify behavior of the web application and are dynamically (re)configurable while the instance of the web application is running. The (re)configured rules are dynamically effective without requiring web application redeployment, even if (re)configured while the instance of the web application is running. The instance is controllable responsive to the evaluation.

Methods, apparatus, systems, and articles of manufacture are disclosed to generate usage dependent code embeddings. An example apparatus includes parsing circuitry to select a usage context of a code snippet including at least one line of code (LOC) before the code snippet or an LOC at which the code snippet is called, the code snippet, and at least one LOC after the code snippet or the LOC. The example apparatus additionally includes embedding circuitry to generate a first list of token embedding vectors for first tokens of a second list of tokens for the code snippet and a third list of token embedding vectors for second tokens of a fourth list of tokens for the usage context. The example apparatus also includes concatenation circuitry to concatenate a transformed token embedding vector of a close token and a fifth list of transformed token embedding vectors for the first list.

Methods, systems, and media enabling a progressive web application (PWA) across a web domain are provided. The PWA may be enabled by web applications among a plurality of web applications executing respective portions of the PWA functionality via linking a root level web page to a manifest. The manifest may contain metadata describing a PWA architecture across the web domain. Enabling the PWA may further include executing, by a root service worker, one or more scripts configured to enable registration by one or more component service workers according the manifest To enable the PWA, applications among a plurality of web applications, and registering, by the one or more component service workers, the web applications among the plurality of web applications.

Systems and methods for providing reliable and efficient data transfer involving a user browser configured to run JavaScript which permits a user browser to communicate with components of a media distribution system. The user browser may request specific media content on the company website which may inform components of the media distribution system of the request. To facilitate the downloading of the requested media content, components of the media distribution system may arrange for the generation of a torrent files, informing the user browser where the requested media content may be downloaded. A fake torrent file may be generated and distributed to the user browser to permit viewing of the media content before generation of a real torrent file is possible. Upon receiving the torrent files, a user may download and play the media content.

Techniques are described herein that are capable of implementing a client-side policy on client-side logic. The client-side policy is configured to support client-side hooks by configuring a rule in the client-side policy to be applied to the client-side logic, which is configured to be executed in a browser of a client device in a network-based system. The rule indicates an administrator-defined action to be performed in response to a request to execute the client-side logic. The request to execute the client-side logic in the browser is received. The administrator-defined action is performed based at least in part on the rule in the client-side policy in response to receipt of the request.

Systems and methods for storing information in a web browser by dynamically generating service worker codes are provided. In one example, an online system receives a request from a client device to store data included in the request in a service worker code. The online system modifies a source code of a particular service worker code to include the data to be stored and transmits the modified service worker code to the client device. The client device receives and stores the modified service worker code embedded with the data. The client device receives a request for a particular data associated with a web page and determines that the modified service worker code contains the requested particular data. The client device retrieves the requested particular data from the modified service worker code and updates the web page with the retrieved particular data.
