Abstract: In some implementations, a computing device can transfer a playback queue between the computing device and a playback device. For example, the computing device can detect when the computing device is within a threshold distance of a playback device. The computing device can establish a connection to the playback device and receive state information describing the media playback state of the playback device. The computing device can determine the media playback state of the computing device. The computing device can present graphical user interfaces for initiating a transfer of a playback queue between the computing device and the playback device based on the playback state of the devices. The computing device can initiate a transfer of the playback queue in response to user input to one of the graphical user interfaces or automatically based on the context of the computing device.

Abstract: In some implementations, a computing system can be configured so that a first user device can delegate a first user's media account credentials to second user device corresponding to a second user. For example, a playback device may be configured with the second user's media account credentials for accessing media items through a network media service. A first user may wish to play media items associated with the first user's media account credentials on the playback device. To do so, the first user device can request a device identifier for the playback device, request and obtain a delegate token for the device identifier from the media service, and provide the delegate token along with media item information to the playback device. The playback device can then use the delegate token to request the media item associated with the first user's media access account.

Abstract: Systems and methods are described for rate-limiting a message-sending client interacting with a message service based on dynamically calculated risk assessments of the probability that the client is, or is not, a sender of a spam messages. The message service sends a proof of work problem to a sending client device with a difficulty level that is related to a risk assessment that the client is a sender of spam messages. The message system limits the rate at which a known or suspected spammer can send messages by giving the known or suspected spammer client harder proof of work problems to solve, while minimizing the burden on normal users of the message system by given them easier proof of work problems to solve that can typically be solved by the client within the time that it takes to type a message.

Abstract: A method and an apparatus that provide rewriting code to dynamically mask program data statically embedded in a first code are described. The program data can be used in multiple instructions in the first code. A code location (e.g. an optimal code location) in the first code can be determined for injecting the rewriting code. The code location may be included in two or more execution paths of first code. Each execution path can have at least one of the instructions using the program data. A second code may be generated based on the first code inserted with the rewriting code at the optimal code location. The second code can include instructions using the program data dynamically masked by the rewriting code. When executed by a processor, the first code and the second code can generate identical results.

Abstract translation: 描述提供重写代码来动态地屏蔽静态嵌入在第一代码中的程序数据的方法和装置。 程序数据可以在第一个代码中的多个指令中使用。 可以确定第一代码中的代码位置（例如，最佳代码位置）用于注入重写代码。 代码位置可以被包括在第一代码的两个或多个执行路径中。 每个执行路径可以具有使用程序数据的指令中的至少一个。 可以基于在最佳代码位置插入重写代码的第一代码来生成第二代码。 第二代码可以包括使用由重写代码动态屏蔽的程序数据的指令。 当由处理器执行时，第一代码和第二代码可以产生相同的结果。
