This week we chat about WWDC 2017 with Tammy Coron and Greg Heo. We answer #askMTJC’s from Shawn Marston, Vic Hudson and Mike Pollard. We follow up on no longer being able to prompt for reviews, making $80,000 per month on the AppStore, Apple Park in open and we look at or rather laugh at WWDC 1997. Greg and Mark regale of tales from the McEnery Convention Center, home of WWDC 2017 and neighbor to AltConf 2017. We all chat about WWDC sessions; Core ML, Vision, Xcode 9, Swift 4, frameworks and lunch sessions. Picks: MLCamera – Vision & Core ML with AVCaptureSession Inceptionv3 model, New rules following WWDC 2017 – App Store Review Guidelines History, Apple Platform SDK API Differences and Visual Studio Code.
This week we are joined by Tammy Coron and Greg Heo. We follow up on Learning to Learn, a MacBook Pro saving a life, where Apple products are made and the math behind a 5-star rating. This week marked the 10 year anniversary of the iPhone announcement by Apple. So we asked listeners and friends to tell us what the iPhone has meant to them. We hear from Kim Ahlberg, Justin Stanley, Aaron Douglas, Peter Cook, George Stroumboulopoulos, Jaime Lopez Jr and Rich Turton. We talk about Phil Schiller’s press tour on the iPhone early history as well as some recent turnaround in iPhone sales and market growth. We speculate Chris Lattner’s move to Tesla. Cloud storage is mentioned. Picks: Kaleidoscope, Hyperdrive USB Hub
// For x 5 stars, and 1 1 star, the average is:
Ave = (5x + 1) / (x + 1)
// Solve for x to get the number of 5 stars needed to achieve this Ave with 1 star:
5x + 1 = (Ave)x + Ave
(5 - Ave)x = Ave - 1
x = (Ave - 1) / (5 - Ave)
// So to get Ave = 4.75, with 1 1-star, you need:
x = 15 5 stars
// And to get Ave = 4.5, you need:
x = 7 5 stars
// Say you have one 5-star and one 1-star. What’s the average?
(1 + 5) ÷ 2 = 3 stars! // How horrible!
// Then you get another 5-star review. Your new average:
(1 + 5 + 5) ÷ 3 = 3.7 stars. // Getting better.
/* So you could just keep adding another 5 and increasing the number after the ÷ until you hit 4.5.
As Mark says, 7 5-star reviews is the magic number to get back up to four and a half: */
(1 + 5 + 5 + 5 + 5 + 5 + 5 + 5) ÷ 8 = 4.5
