Abstract: Technology related to determining a user engagement with software programs is disclosed. In one example of the disclosed technology, a method can include receiving a plurality of signals indicating states of the computer and a software application executing on the computer. The method can include combining the signals to determine a user engagement with the software application. The method can include storing a user engagement log based on the determined user engagement with the software application.

Abstract: Techniques are described for obtaining user activity information and navigational mnemonic information. The activity information and navigational mnemonic information can be used to control information presented in displays in a manner that can assist a user in locating an activity using displayed navigational mnemonics. User activity information can include an application identifier and a content identifier. Navigational mnemonic information can include a resource identifier and a relevance identifier. A user can search for activities based on a relationship between a navigational mnemonic and an activity, such as a temporal relationship. Applications can register both activity information and navigational mnemonic information through an interface, and a navigational mnemonic feed service can provide navigation mnemonics that are not directly related to user activity on user computer devices.

Abstract: Disclosed is a method of treating in a subject hair loss disorders that are beneficially treated by administering a JAK1 and/or JAK2 inhibitor. The method comprises administering to the subject an amount in the range of about 4 mg to about 50 mg of Compound (I): or a pharmaceutically acceptable salt thereof. This invention also provides compositions comprising Compound (I) and the use of such compositions in the described methods.

Abstract: Technology related to an activity feed service is disclosed. In one example of the disclosed technology, a method can include receiving updates to activity streams, where a respective activity stream indicates an engagement of a respective user with applications executing on a respective client device connected to a network. The different activity streams associated with a particular user can be merged to generate a merged activity stream associated with the particular user. The different received activity streams can correspond to different respective client devices. The merged activity stream associated with the particular user can be transmitted over the network.
