- 1. Bohyun Kim (@bohyunkim) Associate Director, LibraryApplications and Knowledge Systems University of Maryland, Baltimore HS/HSL http://bohyunkim.net/blog Slides: http://www.slideshare.net/bohyunkim/getting-started-with-coding NN/LM SEA Webinar | Feb. 18, 2015 | #seacode
- 2. LearningHow toCode isPopular Now! http://www.codecademy.com/
- 12. DiverseGroupsofPeopleLearningHowto Code • Kids • Journalists • Real-estate investors • Academics in digital humanities (literature, history, classical studies/philology) • Scientists • Politicians • Librarians

- 21. 4ThemesforToday 1) Why learn how to code? 2) What does coding, scripting, programming exactly mean? 3) What is it like to teach oneself how to code? 4) Tips and resources
- 22. (1)WhyLearnHow toCode? • Dress up or dynamic webpages • Website redesign • LibGuide customization • How to use CMS • Mobile-friendly/responsive library website • Customize/Add features to library systems • Example:GVSU Library Lab (https://gvsulib.github.io/) • Data processing in batch; automation
- 23. WhatYouCan Do withCoding • Write plug-ins • LibX, Zotero, etc. • Full-blown programs • http://showoffyourapps.challengepost.com/ • http://librarylab.law.harvard.edu/projects.html • http://www.nypl.org/collections/labs • http://code.library.arizona.edu/gots/ • Relevance to librarianship • Understand better the information systems and everyday software • Improve communication and collaboration with IT
- 28. It’sCalleda Languagefora Reason • Syntax: It has its own quirks. • Core concepts: • Variable • Constant • Array • Loop • Function • Object • Class • A programming language CANNOT be learned in a day or a month. • Practice: It takes a lot of time to master. • Very cool to see mastery in action.
- 29. Funky andforeign-looking • var a = ["do", "re", "mi", "fa"]; var len = a.length; for (var i = 0; i < len; i++) { console.log(a[i]);} • $a = array("do", "re", "mi", "fa"); for ($i=0; $i<count($a); $i++){ echo $a[$i]."<br/>";} • $a = array("do", "re", "mi", "fa"); foreach ($a as $i=>$note){ echo $note."<br/>";} • a = ['do', 're', 'mi', 'fa'] for i in a: print i • JavaScript • PHP • PHP • Python
- 30. Techinical≠Programming • XML • Bootstrap • PHP • API • R • HTML5 • JavaScript • Python • ColdFusion • Node • MashUp • RoR • CSS • .NET • Regex • XPATH • JavaScript • Drupal • VB • Django • XSLT • RDF • Ruby • SPARQL • CakePHP • MySQL • Apache
- 31. (2)WhatIs Programming? • What do you and others mean when they say “coding,” “scripting,” or “programming”? • Programming is NOT knowing how to use a CMS (Wordpress, Drupal) or a certain computer software like Dreamweaver (except IDEs). • Programming is NOT the same as editing HTML, CSS, XML. (http://www.cs.tut.fi/~jkorpela/prog.html ) • Programming is knowing and writing the logic for a computer to execute in a programming language that a computer understands. • N.B. Markup language vs. Programming language
- 33. Markup Language
- 34. • JavaScript • PHP • PHP • Python Programming Language • var a = ["do", "re", "mi", "fa"]; var len = a.length; for (var i = 0; i < len; i++) { console.log(a[i]);} • $a = array("do", "re", "mi", "fa"); for ($i=0; $i<count($a); $i++){ echo $a[$i]."<br/>";} • $a = array("do", "re", "mi", "fa"); foreach ($a as $i=>$note){ echo $note."<br/>";} • a = ['do', 're', 'mi', 'fa'] for i in a: print i
- 36. IsCoding Programming? • The distinction between these two can be murky. • Usually the term, ‘coding,’ is used to include the knowledge of a programming knowledge beyond that of a markup language. • http://blogs.jbllanda.com/markup-language-versus-programming- language/ • Here, I will use both terms – coding & programming – interchangeably. • See the difference between scripting. vs. programming: • https://en.wikipedia.org/wiki/Scripting_language • http://stackoverflow.com/questions/17253545/scripting-language-vs- programming-language

- 55. MyThoughtsonCoding • Not everyone, every child, or every librarian needs to learn how to code. • Learning how to code does not have to result in you becoming an expert or full-time coder. • Identify your goal in learning how to code. • Understanding how computer code works will help you navigate everyday information landscape. • You will understand better how software and systems are built, function, and maintained.
- 56. • Variable • Array • Loop • Function • Objet • Class • ….. http://cheezburger.com/6240227584
- 62. LotsofResources • Many resources online – discussions, tutorials, books… • W3SchoolsTutorials • Tuts+ • MOOC • Codecademy / CodeYear • Lynda.com;Treehouse; Code School • Pick One and ACTUALLY DOING IT • Code4Lib listserv/IRC/journal/conference • LibTechWomen (http://libtechwomen.org/) • Library CodeYear Interest Group – ALA (LITA/ALCTS)
- 63. It IsHard… • Syntax will throw you off. • More time will be spent on debugging than code writing. • A slow learning curve. • Not enough time to dedicate to intensive learning. • Not always a clear connection with your library work. • Life intervenes. • Coding is more BORING than exciting.
- 64. Practice!
- 66. Tips • Don’t be discouraged or frustrated. You are teaching yourself a language. • Be persistent and realistic. • Set small goals that solve real-life problems. • Form or join a study group & find like-minded folks! • Comment your code and document since you will forget what you have learned and made.
