Protocol-oriented programming is strongly recommended in the Swift community, and Apple has given a lot of guidance on how to use it in your everyday code. However, there has not been a lot of attention on when it is not appropriate, and what to do in that case. We will explore this idea, and show that there is a completely straightforward and mechanical way to translate any protocol into a concrete datatype. Once you do this you can still write your code much like you would with protocols, but all of the complexity inherit in protocols go away. Even more amazing, a new type of composition appears that is difficult to see when dealing with only protocols. We will also demo a real life, open source library that was originally written in the protocol-oriented way, but after running into many problems with the protocols, it was rewritten entirely in this witness-oriented way. The outcome was really surprising, and really powerful. https://twitter.com/mbrandonw https://appbuilders.ch

try! Swift NYC Conference 2019 - try! Swift is an immersive community gathering about Apple Technologies, Swift Language Best Practices, Application Development in Swift, Server-Side Swift, Open Source Swift, and the Swift Community in New York! Topic - Getting Started with Combine Speaker - Shai Mishali Twitter - https://twitter.com/freak4pc Presentation Link - https://speakerdeck.com/freak4pc/getting-started-with-combine-try-swift-nyc-2019 Bio - Shai is iOS Tech Lead for Gett, the on-demand mobility company, and is involved in several open source projects on his spare time - mainly the RxSwiftCommunity and RxSwift projects, as well as an international speaker. Author on the upcoming Combine book from raywenderlich.com and a hackathon addict and 1st place winner of BattleHack World Finals 2014. You can find him on GitHub and Twitter as @freak4pc. Abstract - In the last WWDC, Apple has finally released it's very own framework for declarative processing of values over time, making the skill of Reactive Programming a must for your toolset. But what does it actually mean, and why is it at all helpful for you as a developer? What are the tools and constructs Apple provide for us as developers? In this talk you'll learn: * What _is_ Reactive Programming? * How Combine differs from other Reactive Declarative frameworks * Basic building blocks: Publisher, Subscriber, Subscription, Subjects and more * The anatomy and lifecycle of a Combine event * Combine vocabulary: Operators - the 'words' that make up your Combine chain * Combine & Foundation: Apple-provided APIs to ease your day-to-day development with Combine and existing Swift APIs * Combine's role in SwiftUI * What is Backpressure? * And much more ... try!

The closest professions to teaching are stage acting and stand-up comedy. Learn how they do it. [D]on’t focus on subtleties that interest you; focus on your audience.

More and more, I try to live in harmony with the seasons, not the clock. ​ It turns out that in northern Norway, “people view winter as something to be enjoyed, not something to be endured,” says Leibowitz, and that makes all the difference. ​ “there’s no such thing as bad weather, only bad clothing”

The system, then, does not particularly care for the individual user as much as it thrives on the decomposition and recomposition of the data that users provide Being shown what you are “supposed” to see is central to what social media offer (the promise of self-expression is mainly an alibi for that larger surrender to algorithmic recommendation); they allow us to consume that passivity toward what we want as pleasurable in itself.

We have a responsibility to learn the underpinnings of the standard of living we all enjoy. To understand and appreciate how we got here, and what it took. And ultimately, to keep it going

To hold someone's attention with a blank slate, all that's necessary is to put another blank slate beside it. You don't have to write anything on either of them. I start to think about the many selves I project, and how the phones work to align them beside themselves, inviting comparison.

I don’t want to suggest that we should resist change entirely. I do think we can be thoughtful about the rate of change that we introduce. I also think it’s a choice, rather than an inevitability, to drop bombs that throw an entire ecosystem off-balance. I tend to interpret this dismissiveness as a way of saying, “We don’t want to become a ‘thing’ because ‘things’ are destroyable by outsiders.” Avoiding labels is a way of keeping hidden cities away from the colonizers, like a nomadic tribe on the move.

i let summer take over the house for however long it needs --- making their way from meal to meal across the sky --- it’s not quite true that every car should stop while a poem is in operation but try to tell me it wouldn’t be nice

The problem, and it’s obvious, is that whatever sucks that I’m running away from will be there once I stop working. or doing things like not being available on the weekends, because they’re the weekends.

but `parseNonEmpty` gives the caller access to the information it learned, while `validateNonEmpty` just throws it away. Consider: what is a parser? Really, a parser is just a function that consumes less-structured input and produces more-structured output.

Lenses have gained some traction in the functional programming world, mainly in haskell. However, they are still viewed as a largely complicated, difficult, high level concept that is not really worth it to invest in learning or putting in your code base. It can be hard to get a good overview on what they actually are and how one can use them. They seem to be somewhat related to getters and setters, but what does that really mean? In addition, it seems to be one of the deepest rabbit holes around. Surely something like this can't be of interest for an everyday working programmer, trying to solve real world problems? Wrong! In this talk, it's my goal to give a brief overview of what lenses are. But more importantly, I will also try to present a "slice" of the world of lenses that is not only directly applicable and useful in our daily work, but is also strangely familiar to people coming from an imperative/object oriented background. Sara Fransson Sara is a software engineer by day and a math enthusiast by night. Sometimes the two worlds collide (and sometimes they make them collide by banging them together). After having taken several trips back and forth between academia and industry in an attempt to balance their love for both the pure abstract theory and the practice of leveraging it to solve concrete problems, they have landed in the core banking domain at Klarna. There they are making themself busy spreading the gospel of functional programming and type theory. When they're not busy building a bank or trying to find time for studying, they enjoy cooking and eating tasty vegan food and playing tetris as fast as possible.

How would you attack a pass code entered into a keypad without an "enter" key? Would requiring an enter key improve security more than requiring another digit?

I think doing math professionally can be stifling as it can feel like you’re expected to know everything while staying collected. This blog is my outlet to do my best to grow as a mathematician while giving myself and others permission to be wrong, ignorant, and emotional about math!

We also saw it’s possible to multiply things that aren’t numbers, and in that case we may not have... associativity, for instance. But that’s not a bad thing. In fact, it’s a beautiful thing!
