Due to the ample amount of internet - sharing and getting knowledge becomes simple and cost-effective. Nowadays, many schools provide online classes in all areas of the study. This simplicity and easiness attract more and more students towards acquiring knowledge online. According to a private company which helps users to find the best cost-effective coding bootcamps, between the year 2018 and 2019, online coding bootcamps increased 177% based on a market study of 79 cities in US and Canada. With the growth in online coding classes and bootcamps, need arise for tools to help instructors and students to get the highest benefits of the new methods of learning and delivering a lecture. The main problem of this kind of learning is the environment, in the coding/programming field setting up infrastructure and environment is the most crucial part. Another issue is the interaction between instructor and student and progress tracking. In this report, I will be focusing on providing a solution for two main issues: 1) Environment setup, 2) Progress tracking. This report includes my approach to solving these problems by developing software and description of its implementation. iv TABLE OF CONTENTS SIGNATURE PAGE .......................................................................................................... ii ACKNOWLEDGEMENTS............................................................................................... iii ABSTRACT.......................................................................................................................iv LIST OF FIGURES ........................................................................................................... vi CHAPTER 1: INTRODUCTION ....................................................................................... 1 CHAPTER 2: COLLABORATIVE CODE EDITOR ........................................................ 4 2.1 ACE code editor ................................................................................................... 5 2.2 Collaboration on editor......................................................................................... 6 2.3 Conflict resolution ................................................................................................ 7 CHAPTER 3: TERMINAL ON WEB ................................................................................ 8 3.1 Use of terminal ..................................................................................................... 8 3.2 REPL Concept ...................................................................................................... 9 CHAPTER 4: IMPLEMENTATION ............................................................................... 10 4.1 Overview ............................................................................................................ 10 4.2 Software/Platform requirement .......................................................................... 15 4.3 Open-source libraries used ................................................................................. 17 4.4 Deployment details ............................................................................................. 19 4.5 REST APIs ......................................................................................................... 22 4.6 User interface ..................................................................................................... 28 CONCLUSION................................................................................................................. 34 REFERENCES ................................................................................................................. 35 v LIST OF FIGURES Figure 1: Online bootcamp market growth between year 2018 and 2019.......................... 2 Figure 2: Collaborative text editor with user presence based on Firepad library ............... 6 Figure 3: Basic OT diagram and conflit resolution ............................................................ 7 Figure 4: REPL concept in flowchart ................................................................................. 9 Figure 5: User Diagram of the Co-IDE System................................................................ 11 Figure 6: Sequence diagram for instructor user................................................................ 13 Figure 7:Sequence diagram for student user..................................................................... 14 Figure 8: Firepad example with ACE code editor available on https://firepad.io/ ........... 17 Figure 9: GoTTY running example and accessing CLI to a web browser ....................... 19 Figure 10: Instructor's view for starting a new coding class/session................................ 29 Figure 11: Student's view once receive invite url from instructor.................................... 30 Figure 12: Instructor's three column view with student list, code editor and terminal..... 31 Figure 13: Student's view with code editor and terminal view once registered ............... 33 vi CHAPTER 1: INTRODUCTION The online classrooms are getting more popular these days in all field of studies. Due to the ample amount of internet - sharing and getting knowledge becomes simple and cost- effective. Nowadays, online courses have become prominent in schools, particularly for field of Computer Science. Also, Computer Science is the field that every other field of study and industry are integrating with. So, the requirement for learning coding/programming and concepts of computer science are highly on demand. On a small scale, schools offer online courses that have time, physical, instructor availability constraint. In this form of course offering, materials are presented through recorded lectures, problem sets, and readings, and students and professors use mechanisms such as discussion forums to communicate.[1] This simplicity and easiness attract more and more students towards acquiring knowledge online. As per the number published by Oregon State University, from 2013 to 2015, attendance in the CS classes in e-campus program – online course offering program - grew from 100 to more than 2,000 paying students.[4] According to a private company which helps users to find the best cost-effective coding bootcamps, between the year 2018 and 2019, online coding bootcamps increased 177% based on a market study of 79 cities in US and Canada. This market study shows 49% increase in coding bootcamp graduation, this growth includes in-person and online bootcamps. That means in-person method only able to grow by 31% whereas online method increased by 177%. In terms of number of students in online form of bootcamps, number increased from 2022 to 5519 students.[2] This numbers 1 clearly mentions popularity of online courses among learners. ONLINE BOOTCAMPS On line cod ing bootcamps are growing faster than in-person; 5,519 (of the total 23,043 students) wi ll graduate from full-time, online coding bootcamps in 2019. ~ ~~ II c,9-.0 24.3 WEEKS 12,900 ? - ,'1".,. e ONLINE BOOTCAMPS ARE l- LONGER + LESS EXPENSIVE THAN IN-PERSON SCHOOLS 2018 2019 Figure 1: Online bootcamp student graduation market growth between year 2018 and 2019[2] All the benefits come with issues and new problems, as these online programs provide convenience of time, commute and availability at a same time it also causes issues like environment setup and tracking of students’ progress during the session. On-campus instructors can easily interact with their students to resolve problems and keep track of their progress, but massive open online course (MOOC) students have fewer chances to interact with instructor and the other way around, which could limit efficiency of this kind of wonderful programs. Authors of one study suggest that MOOCs cannot offer the social experience of on-campus courses, which limits their effectiveness. [1][4] In computer science specifically in coding courses, environment setup is most important part. For on-campus courses, students have access of infrastructure with proper environment setup but on the 2 same time for online courses there is no such facility that accommodated course requirement. The students have to setup entire environment or in worse case they have to purchase new hardware which is not cost-effective.

    Basic Guide: Using VIM Introduction: VI and VIM Are In-Terminal Text Editors That Come Standard with Pretty Much Every UNIX Op

    Basic Guide: Using VIM Introduction: VI and VIM are in-terminal text editors that come standard with pretty much every UNIX operating system. Our Astro computers have both. These editors are an alternative to using Emacs for editing and writing programs in python. VIM is essentially an extended version of VI, with more features, so for the remainder of this discussion I will be simply referring to VIM. (But if you ever do research and need to ssh onto another campus’s servers and they only have VI, 99% of what you know will still apply). There are advantages and disadvantages to using VIM, just like with any text editors. The main disadvantage of VIM is that it has a very steep learning curve, because it is operated via many keyboard shortcuts with somewhat obscure names like dd, dw, d}, p, u, :q!, etc. In addition, although VIM will do syntax highlighting for Python (ie, color code things based on what type of thing they are), it doesn’t have much intuitive support for writing long, extensive, and complex codes (though if you got comfortable enough you could conceivably do it). On the other hand, the advantage of VIM is once you learn how to use it, it is one of the most efficient ways of editing text. (Because of all the shortcuts, and efficient ways of opening and closing). It is perfectly reasonable to use a dedicated program like emacs, sublime, canopy, etc., for creating your code, and learning VIM as a way to edit your code on the fly as you try to run it.

    Appendix a the Ten Commandments for Websites

    Appendix A The Ten Commandments for Websites Welcome to the appendixes! At this stage in your learning, you should have all the basic skills you require to build a high-quality website with insightful consideration given to aspects such as accessibility, search engine optimization, usability, and all the other concepts that web designers and developers think about on a daily basis. Hopefully with all the different elements covered in this book, you now have a solid understanding as to what goes into building a website (much more than code!). The main thing you should take from this book is that you don’t need to be an expert at everything but ensuring that you take the time to notice what’s out there and deciding what will best help your site are among the most important elements of the process. As you leave this book and go on to updating your website over time and perhaps learning new skills, always remember to be brave, take risks (through trial and error), and never feel that things are getting too hard. If you choose to learn skills that were only briefly mentioned in this book, like scripting, or to get involved in using content management systems and web software, go at a pace that you feel comfortable with. With that in mind, let’s go over the 10 most important messages I would personally recommend. After that, I’ll give you some useful resources like important websites for people learning to create for the Internet and handy software. Advice is something many professional designers and developers give out in spades after learning some harsh lessons from what their own bitter experiences.

It carries a legacy that Vcan be traced back to the 1970s, when Vi was born as the ‘visual mode’ for the Unix line editor, Ex (Ex itself was the eXtended version of the editor, Ed). The most jarring part of that legacy for new users is that PRO TIP Vim has two main operating modes. “:help vim-modes” helps Command Mode is where you interact with Vim to to explain Vim’s operating modes move around, alter, save and exit; pretty much everything you can think of except the one thing you might want to do: type text into it. That’s what the Vim benefits from many online learning resources, like other mode (Insert Mode) is for.

    A Web-Based Editor for Cloud-Based Programming

    A Web-Based Editor for Cloud-Based Programming Jan Bracker Master’s Thesis submitted in March 2014 Christian-Albrechts-Universität zu Kiel Institut für Informatik Arbeitsgruppe für Programmiersprachen und Übersetzerkonstruktion Advised by: Prof. Dr. Michael Hanus Eidesstattliche Erklärung Hiermit erkläre ich an Eides statt, dass ich die vorliegende Arbeit selbststän- dig verfasst und keine anderen als die angegebenen Quellen und Hilfsmittel verwendet habe. Kiel, ii Abstract Today’s programmers and development tools still use concepts and work- flows that were introduced with the early operating systems. Programs are still structured in files and to reuse code a developer still has to search and integrate appropriate libraries all by herself. One way to solve these problems is to structure source code using the semantic concepts a language offers and store them in a database to allow structured access and a more advanced search and support for reuse. These ideas lead to the concept of a code cloud. Last year a group of students at the Christian-Albrechts- University developed such a code cloud; they called it Claude. It supports simple Haskell code, up- and download of Haskell packages, and offers search functionality for the code. Though there are Haskell specific features the general structure of Claude is language independent and is supposed to fit as many languages as possible. This thesis extends Claude with a web-based editor to develop new packages in the code cloud and release them. The editor by design is also kept language independent, but offers integration of language specific features. iii Contents 1 Introduction1 2 Foundations and Technologies5 2.1 JavaScript...............................5 2.1.1 JavaScript Object Notation................6 2.1.2 Language Description...................6 2.1.3 Utility Libraries.......................8 2.1.4 CodeMirror: Editor Component............
