Networking. If you’re interested in learning more about OpenFlow and software-defined networking but need to do this on a shoestring budget in your home lab, a number of guides have been written to help out. First up is Brent Salisbury’s how to build an SDN lab without needing OpenFlow hardware. Servers/Hardware.

While we aren’t expecting any announcements on the level of Apple’s shift to custom silicon in its computers, which was WWDC 2020’s big news, Apple presumably has some notable changes in the works for iOS, iPadOS, macOS, and its other operating systems. Read on to learn everything we expect from the big show.

First up is a treatise from Mircea Ulinic on whether network automation is needed. I first ran into Forward Networks a few years ago at Fall ONUG in New York.

Many iPhone users and Apple fanboys alike stand by their product no matter how limited Apple makes their storage capacities, while Android geeks have long time been able to freely add storage/memory cards to their devices and take advantage of more powerful hardware. Aesthetics, Hardware and Price. iPhones have a beautiful design.

This means that basically, just like Hyper-V the hypervisor is native to the operating system. A better comparison would be with XenClient which I wrote about here. The foundation of the traditional VDI solutions has been based on screen streaming technology which requires an always on network connection.
