Chinese search engine Baidu is trying to speed the performance of its deep learning models for image search using field programmable gate arrays, or FPGAs, made by Altera. Baidu has been experimenting with FPGAs for a while (including with Altera rival Xilinx’s gear) as a means of boosting performance on its convolutional neural networks without having to go whole hog down the GPU route. FPGAs are likely most applicable in production data centers where they can be paired with existing CPUs to serve queries, while GPUs can still power much behind-the-scenes training of deep learning models.

Apache Mesos co-creator and former Twitter lead engineer Benjamin Hindman is joining the startup Mesosphere, which provides commercial backing for the open-source Mesos resource management system. Hindman will help Mesosphere build out its first distributed operating system (OS) that will use Mesos as the OS kernel, which is essentially the part of the OS that’s responsible for managing system resources. Twitter, Airbnb, PayPal and Netflix are all companies that use Mesos to help manage their infrastructure. In June, Mesosphere announced a $10.5 million series A round.

Once you upgrade to the latest Microsoft-owned Skype client for iOS 8, you’ll be able to answer incoming voice or video calls much faster. The newest Skype version takes advantage of extensions in Apple’s mobile software, allowing Skype notifications to appear right on the lock screen of an iPhone. These are actionable notifications — both on the lock screen and though the regular drop-down notification method — so one tap picks up the call. The updated Skype client is available for free in the iTunes App Store.
