#ghc15: Natasha Murashev – The Zen Guide to WatchOS
My friend @NatashaTheRobot gave an awesome talk at GHC about WatchOS. I find a lot of tech talks focus on the how, not the why, but she completely inverted it – tying the technical details to the kind of experience you want to create. I’ve been pretty meh on watches (and glasses) because I want fewer…

A Brief Rant about TDD
I’ve been giving this talk about unit testing UI code lately and of course when you talk about testing, TDD (test driven development) keeps coming up. The question ranges from “have you embraced TDD as the One True Way Of Testing, and if not why not because you’re doing it wrong” and “I have heard that…

Over-Engineering Culture, Hacking, and Complexity
I was talking to a fellow escapee of The Conglomerate and we were talking about over-engineering culture. In the sense of “lol things built because it was time for someone to get promoted” and in the sense of complexity. The thing about layers and layers of (debatably necessary) abstractions is that they make things that should…

Refactoring and Legacy Code
The first iOS project I worked on was a big mess that shipped without unit tests. It was a project that had had a number of different directions taken from a product perspective… and the code was like an archeological record of them. Since then I’ve worked on various things, most of which have been greenfield…

Giving a Talk and a Workshop – in Two Days
Submitting I have two ways of submitting to CfPs. The first: a carefully written abstract of a talk that I have already prepped, and probably already given. The second: something that I have already been exploring in blog posts, collected into a “here is this thing that I think I could talk about, but I’m…

Some Thoughts on Mocking
When do we use mocks and when shouldn’t we? Some thoughts: Don’t Mock Data Structures We wouldn’t mock an NSArray or an NSDictionary, so why would we mock our own data structures? Data structures should be simple and well tested, so we can trust them to behave as they should. It will be…

Discoveries About OSS Culture
I was hanging out with an OSS-dude (OSS = Open Source Software) for a while, and I learned a couple of things. Firstly – don’t try and buy committed OSS types books. It’s a complete nightmare. Secondly – I’ve reached a better understanding of harassment and open source. And particularly the pushback, which comes from…

Unit Testing on iOS: Beyond the Model
I want to introduce you to my app, it’s called Show and Hide. It’s an image processing app. This is V1, so the UI is pretty simple, so I think it’s a reasonable example. Briefly, what the app does is it detects the dominant color in an image, and creates these cool partially colored images…

Launching! iOS Unit Testing: Beyond the Model
I’m super excited to release something that I’ve been working on for a while. Unit testing on iOS is… not common. And part of the problem is that people don’t know where to start. It can be overwhelming. Building on my years of experience leading iOS apps with over 80% test coverage, including at Google,…
