Contact records are generated based on the collected contact information, where such records are inserted into a contact list. After receiving a query from a user containing a keyword(s) that include a nickname (or portion thereof) of a second user whom the user desires to interact via the current collaborative application, a search is performed in the contact list for any record containing a nickname that is similar to the provided keyword(s). Record(s) in the contact list containing a nickname that exceeds a threshold degree of similarity as the keyword(s) are identified. Such identified records may contain a user identifier which is used to identify the appropriate nickname of the second user associated with the current collaborative application.

This document describes techniques and devices for a radar recognition-aided search. Through use of a radar-based recognition system, gestures made by, and physiological information about, persons can be determined. In the case of physiological information, the techniques can use this information to refine a search. For example, if a person requests a search for a coffee shop, the techniques may refine the search to coffee shops in the direction that the person is walking. In the case of a gesture, the techniques may refine or base a search solely on the gesture. Thus, a search for information about a store, car, or tree can be made responsive to a gesture pointing at the store, car, or tree with or without explicit entry of a search query.

In a server (111), an updater (201) updates a file by an editing process that includes an adding process that adds a record to the end of a file. A collector (202) reads, in order of location in the file, a record included in the file, causes a collection device of a collection system to associate and collect the record and a position of the record in the file, and non-transitorily stores the position as an offset. An estimator (203) estimates whether header records located between the beginning of the file and the recorded offset are updated. When it is estimated that any of the header records are updated, a starter (204) causes the collector (202) to start reading the record from the beginning of the file. When it is estimated that none of the header records have been updated, the starter 204 causes the collector (202 to start reading the record from the recorded offset.

The security engine performs an authenticated cryptographic operation for the data transfer operation. The authenticated cryptographic operation may be AES-GCM authenticated encryption or authenticated decryption. The security engine may perform encryption or decryption using multiple block cipher pipelines. The security engine may calculate an authentication tag using multiple Galois field multipliers. Other embodiments are described and claimed.

Systems, methods and apparatuses of fine grain data migration in using Memory as a Service (MaaS) are described. For example, a memory status map can be used to identify the cache availability of sub-regions (e.g., cache lines) of a borrowed memory region (e.g., a borrowed remote memory page). Before accessing a virtual memory address in a sub-region, the memory status map is checked. If the sub-region has cache availability in the local memory, the memory management unit uses a physical memory address converted from the virtual memory address to make memory access. Otherwise, the sub-region is cached from the borrowed memory region to the local memory, before the physical memory address is used.
