An approach for controlling lighting in a digital video stream is presented. A user loads digital content into a light tracking system. The digital content includes three tracks, which are a video track, an audio track, and a light control track. After loading, the user selects either a “partial light effect setting” or a “full light effect setting.” When the user selects a partial light effect setting, the light tracking system lowers the environmental lighting device's illumination at the beginning of the digital content's playing, and raises the environmental lighting device's illumination at the end of the digital content's playing. When the user selects a full light effect setting, the light tracking system adjusts the environmental lighting device's illumination throughout the digital content's playback, as well as lowering and raising the environmental lighting device's illumination at the beginning and the end of the movie, respectively.

An approach that smoothes a cryptographic function's timing footprint is presented. A processor includes a “function timing smoother” that smoothes out spikes in the amount of time that a particular cryptographic function requires to execute. When a cryptographic function executes, the function timing smoother tracks the amount of time that the cryptographic function executes (current execution time) and compares the time with the amount of time that the same cryptographic function took for a previous execution (previous execution time). When the current execution time is less than the previous execution time, the function timing smoother adds instructions or varies an execution unit's clock speed in order to increase the cryptographic function's current execution time. Using this approach, a malicious user is not able to decipher sensitive information from the cryptographic function's timing footprint.

摘要:
A license handling information handling system receives an electronic message from a first computer system utilized by a first user. The first user's message requests a license to a licensed product that has previously been purchased by the organization. The license handling information handling system identifies a second user in the organization that currently has a license to the licensed product, and requests that the second user relinquish the license to the licensed product. The second user indicates that the second user's license will be relinquished for a temporary time period. The licensing handling information handling system sends an electronic message, including the temporary time period, to the first user. In response to the first user accepting the temporary time period, the second user's license to the licensed product is revoked, and the first user is granted a license to the licensed product.

An approach is provided that receives a message from a first user. The first user's message requests a license to a licensed product that has previously been purchased by the organization. The system identifies current users in the organization that currently have licenses to the licensed product. A need score is calculated that reflects a needs analysis of the first user to the licensed product. Current user need scores are calculated and these need scores correspond to the needs of the current users pertaining to the licensed product. The first user's need score is compared to the current user product need scores and a second user is selected based on the comparison where the first user's need score is better than the second user need score. The second user's license to the licensed product is revoked and the first user is granted a license to the licensed product.

Methods and apparatus, including computer program products, implementing and using techniques for facilitating in-transit meetings between users. Transit information is received for several users. The transit information for at least some users is compared. If an opportunity for an in-transit meeting between at least two users is detected when comparing the transit information, the at least two users are notified about the opportunity for the in-transit meeting.

摘要:
Online activity between a client computer and an online store is electronically monitored to determine that an item referenced in the online activity is a publication, such as a book or periodical. In response, an electronic library database is automatically queried to determine whether a physical or electronic copy of the publication is available from the library. The availability of the publication is communicated to a user of the client computer and the user is given an option to borrow the publication.
