# Programming Languages ### and Programming Paradigms --- CS 135 // 2021-02-02 <!--=====================================================================--> # Welcome! My name is Titus Klinge<br> (Please call me **Titus**) --- <div class="twocolumn" style="font-size: 85%"> <div> **Office:** 305 Collier-Scripps<br> **Email:** <titus.klinge@drake.edu><br> **Phone:** (515) 271-4599 </div> <div> **Office Hours:** (Held via Zoom) By appointment only<br> **M/W:** 2:00–5:00 PM CT<br> </div> </div> --- Message me any time via **Microsoft Teams** <!--=====================================================================--> # Introductions It is time to test each of your microphones! --- 1. <!-- .element: class="fragment"--> I will **badly mispronounce** your name 2. <!-- .element: class="fragment"--> You will attempt to correct my terrible pronunciation by temporarily unmuting yourself 3. <!-- .element: class="fragment"--> Undoubtedly there will be technical difficulties<br>(Responding via chat is also OK) 4. <!-- .element: class="fragment"--> Share one hobby or interest you have <!--=====================================================================--> ## Nonverbal Feedback It is time to test nonverbal feedback features!  --- - <!-- .element: class="fragment"--> If you can find these, click **YES**, otherwise click **NO** <!----------------------------------> ## Nonverbal Feedback - There should also be a **raise hand** button somewhere in your Zoom client - <!-- .element: class="fragment"--> If you know the sculpture from the following picture, **raise your hand** and then I will call on you <!----------------------------------> <!-- .slide: data-background-image="/teaching/2021s/cs135/assets/images/sculpture.jpg" --> <!-- .slide: data-background-size="contain" --> <!--=====================================================================--> ## Polling It is time to test the **polling** feature of Zoom --- 1. <!-- .element: class="fragment"--> Are you a morning person or an evening person? 2. <!-- .element: class="fragment"--> Will you be taking this course from Drake University campus or will you be off campus? 3. <!-- .element: class="fragment"--> What OS will you be using in this course? <!--=====================================================================--> ## DISCUSSION It is time to test the **breakout room** feature of Zoom --- 1. <!-- .element: class="fragment"--> You will be automatically be placed in small groups 2. <!-- .element: class="fragment"--> Introduce yourselves again<br>(if you're like me, you might have already forgot) 3. <!-- .element: class="fragment"--> **Elect a delegate** for your group to take notes to share your discussion with the class - They should share their screen and type up comments so the rest of the group can see 4. <!-- .element: class="fragment"--> I will **randomly** select groups to share with the class <!----------------------------------> ## DISCUSSION Answer the following questions --- 1. <!-- .element: class="fragment"--> Why do so many programming languages exist? - How are they similar? How are they different? 2. <!-- .element: class="fragment"--> Can we group languages into categories? - If so, what are they? <!----------------------------------> ### Why do so many programming languages exist? - A lot of people need specific features, so they go off and make their own language - Languages are evolving and getting better, replacing older ones - A lot of domain-specific language <!----------------------------------> ### Categories of Programming Languages - Different paradigms such as: + Imperative, declarative + Object-oriented + Functional + Logic + Mathematical + Procedural + Reactive <!--=====================================================================--> ## Course Goals At the end of this course you will: --- 1. <!-- .element: class="fragment"--> Be exposed to new programming paradigms - <!-- .element: class="fragment"--> Especially **functional programming** 2. <!-- .element: class="fragment"--> Teach you to "learn how to learn" a new programming language 3. <!-- .element: class="fragment"--> Implement your own domain-specific language <!--=====================================================================--> ## Structure of this Course - First-half of the semester: + <!-- .element: class="fragment"--> Learn functional programming (via Haskell) + <!-- .element: class="fragment"--> Lab-focused / pair programming - <!-- .element: class="fragment"--> Midterm presentations + <!-- .element: class="fragment"--> Learn a new programming language + <!-- .element: class="fragment"--> Teach it to the class - <!-- .element: class="fragment"--> Second-half of the semester: + <!-- .element: class="fragment"--> Implement **our own** programming language---from scratch! <!--=====================================================================--> ## Course Website [analytics.drake.edu/teaching/2021s/cs135](/teaching/2021s/cs135/) <!----------------------------------> <!-- .slide: data-background-iframe="/teaching/2021s/cs135/" data-background-interactive --> <!--=====================================================================--> # Assignment 1 Due **Thursday, February 4th** (before class) 1.
