March 2015 Summaries

As we move towards a more connected lifestyle, understanding how users are connected across multiple devices is crucial. Traditional methods such as cookies and authentication are not supported by all devices like mobile phones, tablets, and traditional televisions. SilverPush has developed a novel system for cross-device ad targeting using ultrasonic "audio beacons." These beacons can help correlate various devices connected to an individual, enabling advertisers to track user behavior across different platforms. The use of audio beacons is becoming increasingly popular in marketing and proximity-based advertising. However, challenges such as corporate responsibility and consumer privacy protection need to be addressed for widespread adoption. SilverPush has managed to scale its system using Aerospike, a NoSQL database solution that provides high performance and cost-effectiveness.

Aerospike, a company dealing with high scalability issues, has found effective solutions to combat memory fragmentation using JEMalloc, a dynamic memory allocator. Memory management is crucial in computer architectures and can lead to performance degradation or memory leaks if not handled properly. JEMalloc provides fast allocation and deallocation of memory while minimizing fragmentation. Aerospike's implementation of JEMalloc optimized memory utilization, reduced fragmentation, and improved overall application performance in multi-threaded environments.
