iPhone 7 may come in three distinct models

Apple's iPhone 7 may come in three distinct models, according to a recent report from Mobipicker. Based on a photo obtained from an anonymous tipster, Mobipicker relays that Apple later this year may release three iPhone models: an iPhone 7, an iPhone 7 Plus and an iPhone 7 Pro.While details remain scant, a three-model release cycle would prove intriguing and would certainly be a shrewd way to bump up iPhone sales that, according to some analysts, have plateaued. That being the case, and based on other rumblings from the rumor mill, there exists a possibility that Apple this fall will release a 4.7-inch iPhone 7, an 5.5-inch iPhone 7 Plus and a 5.5-inch iPhone 7 Pro that will exclusively feature an advanced dual camera system.To read this article in full or to leave a comment, please click here

Mininet flow analytics

Mininet is free software that creates a realistic virtual network, running real kernel, switch and application code, on a single machine (VM, cloud or native), in seconds. Mininet is useful for development, teaching, and research. Mininet is also a great way to develop, share, and experiment with OpenFlow and Software-Defined Networking systems.

This article shows how standard sFlow instrumentation built into Mininet can be combined with sFlow-RT analytics software to provide real-time traffic visibility for Mininet networks. Augmenting Mininet with sFlow telemetry realistically emulates the instrumentation built into most vendor's switch hardware, provides visibility into Mininet experiments, and opens up new areas of research (e.g. SDN and large flows).

The following papers are a small selection of projects using sFlow-RT:

IDG Contributor Network: Time for digital detox? Searching for Wi-Fi becomes normal vacation behavior

Almost a quarter (21 percent) of Americans would rather give up sex than lose Wi-Fi for a month, and 10 percent would give up a friend than forego wireless connectivity.Those are just two of the findings in a survey conducted by a travel agency that runs digital detox tours.Digital detox vacations are trips where social media, smartphone and camera use is banned by the tour organizers.
