CocoaHead Meeting Changes

New Start Time

We are changing the meeting times for our main, second Thursday of the month, meeting.

Doors will now open at 6pm (was 6:30pm) for pizza and socializing. The meeting itself will start at 6:30pm and we’ll shoot to end the meeting at 8:30pm (was 9:00pm). The goal of this change is to be a better guest of Apple and provide their cleaning crew enough time to restore the Briefing Room before the store officially closes.

Please continue to RSVP via meetup.com.

Presentation Etiquette

To help make sure we keep our agenda times, we will now ask that people hold their questions until the end of the presentations, and then give them only when time is available. This should help people stay closer to their planned script as well as make sure everyone on the agenda, including the final speaker, has the expected time to do their presentation. The leadership will make some changes to how we display our timer so everyone is aware where they stand.

If you’d like to present in 2017 contact zorn@phillycocoa.org.

Your Feedback Welcome

If you have any feedback on these or other changes / additions you’d like to see come in 2017 from CocoaHeads, let the leadership know. We may have some extra funding for something new and we welcome your feedback on what that should be.

Thanks for your continued participation in our local Apple developer community.

What Mobile Developers Should Know About Distributed Systems: Part 3, Kevin Lee

This multi-part lightning talk series will focus on important CS concepts and fundamentals that may be helpful for mobile developers to know. Part 3 will talk about Pets v. Cattle a.k.a. Infrastructure Automation.

Main Talks

Design by Intent, Taun Chapman

Good Design is an intentional process. When we make design decisions, those decisions are based on trying to achieve a certain objective. These intents are important to the design process and yet many are ignored by most of our design tools. This talk will highlight how our intents shape our design work. How our tools ignore these intents resulting in lost design information and developer friction. The talk will propose ways our tools or our habits could be modified to easily include the design intent thereby improving usability, reliability and end user satisfaction of the final product.

Dictionary Definition: Intend: “have (a course of action) as one’s purpose or objective”

Main Talk

Bindings, the Best Code is the Code Not Written, Taun Chapman

Cocoa Bindings enables you to establish a live connection between an item of data and its presentation in a view. Any change made to the data’s value, either in the view or in the object that stores the data, automatically propagates across the connection. Using Cocoa bindings reduces the glue code you once had to write to connect a view to its underlying model.

In this talk Taun Chapman will review the components that make up Cocoa Bindings and how he’s used them to great effect in his recent efforts.

An Introduction to Web Sockets, Nathaniel Symer

WebSockets is an advanced technology that makes it possible to open an interactive communication session between a client and server. With this API, you can send messages to a server and receive event-driven responses without having to poll the server for a reply. In this introduction talk Nathaniel Symer will review how the protocol works, what it could be used for, and how to use it safely; including implementing a client in Objective-C.
