5 THE ROAD TO CODE Scott Baumbich, Swift Developer SWIFT DEVELOPMENT

6 What is Swift? Swift is a modern programming language that made its first appearance in June Powerful Intuitive Interactive Fun Concise Expressive

7 How Swift is used in the industry? ios OS X tvos WatchOS IBM Android? Facebook?

8 Focus Choosing Swift as your first programing languag Why do YOU want to program? Time commitment Learning curve Life style

9 Swift Pros Swift is easier to read and write Swift can result in shorter overall code length Swift has some clever tricks up its sleeve Cons It doesn't do everything Objective-C does You need to know Objective- C to debug the code/ framework Since, the language is new the pool of Swift developers is very limited.

10 The job market for Swift developers

11 Questions? Scott Baumbich, Swift Scott-Baumbich SBaumbich

12 Ruby, Rails & my coding journey Nicole Lopez

13 About Me Ruby on Rails engineer at Avant Majored in Arabic Language and Literature Worked in Immigration for 4 years Learned to code through the internet and Meetup groups Started learning with HTML, CSS, Sass, and then Python, Javascript, and eventually Ruby and Rails Started from the front end now I m here

14 How I Learned... Online Coursera -- Introduction to Programming with Python Codecademy -- HTML and CSS Meetups Girl Develop It -- Sass and Javascript Railsbridge -- Intro to Rails Chicago Women Developers -- Basic bash, Ruby Side Projects & Tutorials

15 Ruby

16 What is Ruby? A programming language. a dynamic, reflective, object-oriented, general-purpose programming language

17 Ruby s methods and object types are dynamically determined at runtime rather than compile time. But what does that mean? Ruby uses reflection to modify its own structure and behavior at runtime (think metaprogramming). Follows an object-oriented programming paradigm. In Ruby, everything is an object. Designed for general purpose use across a wide variety of application domains.

18 Why Ruby? Accessible, flexible, friendly community, and overall FUN

19 "I hope to see Ruby help every programmer in the world to be productive, and to enjoy programming, and to be happy. That is the primary purpose of Ruby language." - Yukihiro "Matz" Matsumoto, creator of Ruby pictured >>

20 PROS Ruby is ACCESSIBLE Low barrier of entry to learn Ruby Easy variable and method definitions without static typing Takes care of memory allocation & garbage collection so you don t have to Reads like English Great documentation Gems are plentiful

21 Simple code leveraging the power of Gems

22 PROS Ruby is FLEXIBLE Can write the same thing many different ways Object-Oriented by nature Duck-typing -- if it acts like a duck and quacks like a duck, it s a duck Metaprogramming -- can write code that writes more code

23 Can also define this array with Array.new(...) or [ hearts, diamonds ] Flexibility & brevity of metaprogramming The Deck object holds many Card objects, keeping Deck & Card logic separate. Reads like English

24 CONS With great power comes great responsibility. Metaprogramming -- is a blessing and a curse Not great for concurrency or high performance with real-time data Flexibility allows people to be too clever No strong typing allows for mysterious bugs Easy to depend on gems. Which may not always be 100% reliable or documented

25 Rails

26 What is Rails? An opinionated Model View Controller (MVC) framework written in Ruby that favors convention over configuration.

27 PROS Speed of app development rails generate commands rake commands (ruby make) Great documentation -- many tutorials Tons of features out of the box Database, ORM Server with Rack middleware RESTful routing Web pages with built in templating helpers Mailer, Job processor Test framework Tons of gems optimized for rails

28 What you d see at localhost:3000 when booting up a blank Rails app

29 Accessible documentation across experience levels

30 Helpful Errors

31 CONS For beginners, easy to confuse what s from ruby and what s from rails Rails handles a lot of set-up and configuration from you -- to learn more, you ll need to dig deeper The concept of models in rails can lead to problematic architecture with tight coupling between business logic and objects stored in the database Not performant at scale for same reasons Ruby isn t performant at scale

32 Opportunities in Ruby on Rails

33 Tons of opportunities for Ruby and Rails devs Many companies use Rails including Github, Airbnb, Soundcloud, Avant, Enova, Basecamp, Reverb the list goes on. 83 Ruby opportunities listed on Built in Chicago s job page Rails lends itself to rapid development, so is a language used by many start ups.

34 Main Takeaways Ruby is a great first language for beginners interested in building web apps, and Rails is a great first framework to learn. Rails is a great framework to use to get your app up and running fast. Don t stop learning at Ruby on Rails. Keep digging beneath the surface to further your knowledge! There are tons of job opportunities for Ruby and Rails developers.

40 Let s Talk about Java Not the coffee! Proprietary and Confidential / 2016 The Nerdery, LLC

41 What is Java? Java is a general purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need of recompilation.

59 WHY PYTHON?

60 QUICK INTRO Unrelated college degree Bootcamp grad 2 years in Python Chicago PyLadies Co-organizer 3-legged cat owner

61 WHAT IS!?

62 COMMON USES Data science and academia Web development Scripting

63 THE ZEN OF PYTHON Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated.

64 Sparse is better than dense

65 There should be one --and preferably only one-- obvious way to do it.

66 Errors should never pass silently.

67 POPULAR FRAMEWORKS Django Flask Falcon Pyramid

68 GETTING A JOB IN PYTHON

69 PYTHON DRAWBACKS Large community -> slow to adopt innovation The Global Interperter Lock (GIL) Fewer bootcamps

70 Now is better than never.
