Academic and Educational Static Website Generation Recent Advances in Information Science Academic and Educational Static Website Generation ALMIR MUTAPCIC, Ph.D. Computer Science Department University Sarajevo School of Science and Technology Hrasnička cesta 3a, Sarajevo 72000 BOSNIA AND HERZEGOVINA [email protected] Abstract: - In this paper, we present a solution and a set of good practices for academic and educational static website generation and maintenance. We present a publishing framework based on open-source software such as Jekyll, Pygments, MathJax, Git, and others. We show how a sample educational site can be setup and hosted for free on modern web services such as GitHub, Amazon AWS, and Heroku. Key-Words: - Computer based education, Education, Open source software, Website generation 1 Introduction In this paper, we describe a solution and a set of There are many open-source and commercial good practices for generation and maintenance of blogging and content management system (CMS) academic and educational static websites, based on platforms such as Drupal, Joomla, and WordPress, the following components: which can be used to publish and maintain academic and educational websites. Most of these platforms 1. Jekyll: static site generation generate dynamic sites, in the sense that they require 2.

Recently there have been several attempts to These technologies (in particular Jekyll and Git) are simplify blogging platforms, and hence generation ideal for group collaboration when creating sites for and maintenance of blogging content. One of the educational courses, group research pages, and other more popular new blogging platforms is Jekyll, a similar sites. blog-aware, static site generator written in Ruby. Jekyll takes a template directory, representing a raw form of a website, runs its marked content through 2 Problem Formulation converters (such as Markdown, Textile, or Liquid We would like to find a framework for generation converters), and generates a complete, static website and maintenance of academic and educational sites. The framework would generate static sites and that can be served using Apache, Nginx, or any would not require dynamic server-side components, other web server. Jekyll is also the engine behind such as relational databases to store the site content. GitHub Pages, a service that hosts GitHub users’ The dynamic components should be implemented personal and open-source project pages for free [1]. using the front-end browser technologies, such as In the engineering academic community, jemdoc HTML5, CSS3, and JavaScript. has become a popular tool to generate academic and The framework should favor convention-over- educational static sites. jemdoc is a light text-based configuration, a popular design principle in modern markup language and static site generator written in web frameworks. It should also use LaTeX for Python, with advanced features such as LaTeX typesetting math equations and YAML/JSON for equation generation, table support, and CSS-based configuration markup. YAML and JSON are data styling. Its LaTeX support is the most interesting serialization formats designed for human readability feature for the engineering and math community; and easy interaction with scripting languages [3]. however, it also adds an external dependency on the The framework should use a modern distributed latex and dvipng system executables to process the version control systems, such as Git or Mercurial. embedded equations [2].

Here, we can set any We propose to use Jekyll for the main static site Jekyll predefined variables or custom variables. For generation. We recommend writing the site content example, we use custom variables lecture and lab such as lecture and lab material in GitHub-flavored to declare a lecture or lab post, respectively. markdown format [4]. We augment Jekyll with Pygments for code syntax highlighting [5] and use 3.2 Lecture posts MathJax to display math symbols and equations [6]. Each lecture post is denoted with the lecture field We use Git for version control and distributed that specifies the lecture number. For example, the group collaboration. It is often helpful to setup a first lecture post file with the name 2013-02-25- remote repository for the site on GitHub, BitBucket, lecture-1.md is given below: or a similar provider of hosted Git services.

  • Gitlab Letsencrypt and Certbot
    Gitlab and Certbot – Lets Encrypt SSL and HTTPS In this post we will talk about HTTPS and how to add it to your GitLab Pages site with Let's Encrypt. Why TLS/SSL? When discussing HTTPS, it's common to hear people saying that a static website doesn't need HTTPS, since it doesn't receive any POST requests, or isn't handling credit card transactions or any other secure request. But that's not the whole story. TLS (formerly SSL) is a security protocol that can be added to HTTP to increase the security of your website by: 1. properly authenticating yourself: the client can trust that you are really you. The TLS handshake that is made at the beginning of the connection ensures the client that no one is trying to impersonate you; 2. data integrity: this ensures that no one has tampered with the data in a request/response cycle; 3. encryption: this is the main selling point of TLS, but the other two are just as important. This protects the privacy of the communication between client and server. The TLS layer can be added to other protocols too, such as FTP (making it FTPS) or WebSockets (making ws://wss://). HTTPS Everywhere Nowadays, there is a strong push for using TLS on every website. The ultimate goal is to make the web safer, by adding those three components cited above to every website. The first big player was the HTTPS Everywhere browser extension. Google has also been using HTTPS compliance to better rank websites since 2014. TLS certificates In order to add TLS to HTTP, one would need to get a certificate, and until 2015, one would need to either pay for it or figure out how to do it with one of the available Certificate Authorities.

    ALGOHUB: A WEBSITE OF ALGORITHMS A Project Presented to the Faculty of California State Polytechnic University, Pomona In Partial Fulfillment Of the Requirements for the Degree Master of Science In Computer Science By Liang Zhang 2017 SIGNATURE PAGE PROJECT: ALGOHUB: A WEBSITE OF ALGORITHMS AUTHOR: Liang Zhang DATESUBMITTED: Fall 2017 Computer Science Department Dr. Gilbert S. Young Project Committee Chair Computer Science Dr. Hao Ji Computer Science ii ACKNOWLEDGEMENTS First, I would like to thank my wife, Yatong Liang, for her supporting not only on my study, but also in all aspects of my life. Thanks all the professors I have met in CalPoly Pomona, especially Dr. Young, and Dr. Ji, who taught me knowledge, tutored my research, and encouraged me overcoming the barricades. Last but not the least, thanks all the developers, who are contributing to the open source projects, for building so many wonderful software. Without your works, I couldn’t have finished my project. iii ABSTRACT In this project, a website (AlgoHub) is implemented, which mainly hosts contents of algorithms, such as title, algorithm description, applications, and so on. From the functionality perspective, modules like adding, modifying, searching, fulfills the requirements of different groups of users (students, teachers, software engineers, and etc.) who are interested in algorithms. From the technology perspective, the system architecture of AlgoHub is designed to achieve high performance and scalability according to the nature of this application. During the implementation, rather than building a website from scratch, many practically proved technologies and existing components, such as Jekyll, Jenkins, Git, and so on, are utilized after being carefully evaluated.

    The EICUG Software Website - an update Maxim Potekhin (BNL, NPPS) 09/02/2020 Why are we here? ● For many organizations their website is an important tool and an asset. ● Moreso for knowledge-intensive fields like ours. ● Let’s take stock of where we are with the website, decide on what can be improved or changed, and define items for future development. ● The content is a separate topic, these slides are mostly “how-to”. 2 Overview ● The website has been online for ~6 months https://eic.github.io/ ● See presentation from April 2020 for intro and general idea of the site ○ https://docs.google.com/presentation/d/1WCVlVNZldHm8exHJBhILLngr9yEXHUP1w_BdwB4F41s/edit?usp=sharing ● Healthy level of contributions to the site from the team members ○ A proof that the system is reasonably user friendly ● Changes to the layout can be done quite quickly ○ Not a problem to create a new skin, menu, color scheme, layout etc ● GitHub based ○ Free hosting with service level we are happy with for now ○ Pull requests make collaboration easy ● How are things looking going forward? What have we learned? 3 Updated layout/menus - recent changes 4 Updated layout/menus, cont’d 5 The platform ● Static site = security + performance. ● Template-based, hence separation of content and layout ● Jekyll is one of a few available static website generators. ● Markdown/Jekyll/Liquid/Bootstrap + GitHub. ● Jekyll does allow for a fairly liberal mix of HTML and MD for considerable flexibility ○ ...with a few caveats ● YAML, CSV and JSON files containing configuration and data are transparently parsed - creating data structures in an intuitive way ○ Example: migration of data from Postgres requires one line of sql and nothing else ● Manipulation of structured data is perhaps the most important feature.

    Cross-Platform Software Developer Expertise Learning by Norbert Eke A Thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfilment of the requirements for the degree of Master of Computer Science in Computer Science with Specialization in Data Science Carleton University Ottawa, Ontario c 2020 Norbert Eke The undersigned recommend to the Faculty of Graduate and Postdoctoral Affairs acceptance of the Thesis Cross-Platform Software Developer Expertise Learning Submitted by Norbert Eke in partial fulfilment of the requirements for the degree of Master of Computer Science Dr. Olga Baysal, Thesis Supervisor Dr. Majid Komeili, Internal Examiner Dr. Diana Inkpen, External Examiner Dr. Ahmed El-Roby, Chair of Defence Dr. Michel Barbeau, Department Chair Carleton University 2020 ii Abstract In today's world software development is a competitive field. Being an expert gives software engineers opportunities to find better, higher-paying jobs. Recruiters are always searching for the right talent, but it is difficult to determine the expertise of a developer only from reviewing their resume. To solve this problem expertise detection algorithms are needed. A few problems arise when expertise is put into application: how can developer expertise be defined, measured, extracted or even learnt? Our work is attempting to provide recruiters a data-driven alternative to reading the candidate's CV or resume. In this thesis, we propose three novel topic modeling based, robust, data-driven techniques for expertise learning. Our extensive analysis of cross-platform developer expertise suggests that using multiple collaborative platforms is the optimal path towards gaining more knowledge and becoming an expert, as cross-platform expertise tends to be more diverse, thus creating opportunities for more effective learning by collaboration.
