This repository serves as the official website for the tutorial "Online Clustering: Algorithms, Evaluation, Metrics, Applications and Benchmarking" at this site.

This website is generated using Github Pages, using The Cayman theme.

Cayman is a Jekyll theme for GitHub Pages. You can preview the theme to see what it looks like, or even use it today.

To use the Cayman theme:

1. Add the following to your site's _config.yml:

   remote_theme: pages-themes/cayman@v0.2.0
   plugins:
   - jekyll-remote-theme # add this line to the plugins list if you already have one

2. Optionally, if you'd like to preview your site on your computer, add the following to your site's Gemfile:

   gem "github-pages", group: :jekyll_plugins

Cayman will respect the following variables, if set in your site's _config.yml:

title: [The title of your site]
description: [A short description of your site's purpose]

Additionally, you may choose to set the following optional variables:

show_downloads: ["true" or "false" (unquoted) to indicate whether to provide a download URL]
google_analytics: [Your Google Analytics tracking ID]

If you'd like to add your own custom styles:

1. Create a file called /assets/css/style.scss in your site
2. Add the following content to the top of the file, exactly as shown:

   ---
   ---
   
   @import "{{ site.theme }}";

3. Add any custom CSS (or Sass, including imports) you'd like immediately after the @import line

Note: If you'd like to change the theme's Sass variables, you must set new values before the @import line in your stylesheet.

If you'd like to change the theme's HTML layout:

1. For some changes such as a custom favicon, you can add custom files in your local _includes folder. The files provided with the theme provide a starting point and are included by the original layout template.
2. For more extensive changes, copy the original template from the theme's repository
   (Pro-tip: click "raw" to make copying easier)
3. Create a file called /_layouts/default.html in your site
4. Paste the default layout content copied in the first step
5. Customize the layout as you'd like

Google has released several iterations to their Google Analytics code over the years since this theme was first created. If you would like to take advantage of the latest code, paste it into _includes/head-custom-google-analytics.html in your Jekyll site.

Templates often rely on URLs supplied by GitHub such as links to your repository or links to download your project. If you'd like to override one or more default URLs:

1. Look at the template source to determine the name of the variable. It will be in the form of {{ site.github.zip_url }}.
2. Specify the URL that you'd like the template to use in your site's _config.yml. For example, if the variable was site.github.url, you'd add the following:

   github:
     zip_url: http://example.com/download.zip
     another_url: another value

3. When your site is built, Jekyll will use the URL you specified, rather than the default one provided by GitHub.

Note: You must remove the site. prefix, and each variable name (after the github.) should be indent with two space below github:.

For more information, see the Jekyll variables documentation.

See the open issues for a list of proposed features (and known issues).

The Cayman theme is intended to make it quick and easy for GitHub Pages users to create their first (or 100th) website. The theme should meet the vast majority of users' needs out of the box, erring on the side of simplicity rather than flexibility, and provide users the opportunity to opt-in to additional complexity if they have specific needs or wish to further customize their experience (such as adding custom CSS or modifying the default layout). It should also look great, but that goes without saying.

Interested in contributing to Cayman? We'd love your help. Cayman is an open source project, built one contribution at a time by users like you. See the CONTRIBUTING file for instructions on how to contribute.

If you'd like to preview the theme locally (for example, in the process of proposing a change):

1. Clone down the theme's repository (git clone https://github.com/pages-themes/cayman)
2. cd into the theme's directory
3. Run script/bootstrap to install the necessary dependencies
4. Run bundle exec jekyll serve to start the preview server
5. Visit localhost:4000 in your browser to preview the theme

For users with ARM achitecture CPUs on Macbooks running macOS Big Sur and later, please note that script/bootstrap will not work. It will return an error similar to the following

You don't have write permissions for the /Library/Ruby Gems/2.x.y directory. 
## x,y are arbitrary numbers that represent the version of Ruby

, simply because macOS would not let you change anything with the default Ruby version that come pre-installed with your Macbook.

As such, you should proceed to install the latest version of Ruby with Homebrew, using the tutorial here. This will allow you to have a version of Ruby later than 3.0.0.

However, this should not be enough to work with Github pages. The latest versions of Ruby does not have webrick installed included by default. The following issue from GitHub and the following thread from StackOverFlow also mentioned a similar phemomenon. This issue can simply be fixed by running the command

bundle add webrick

which include the following command into Gemfile:

gem "webrick", "~> 1.7"

Then, we can repeat the command

bundle exec jekyll serve

and everything should be complete.

The theme contains a minimal test suite, to ensure a site with the theme would build successfully. To run the tests, simply run script/cibuild. You'll need to run script/bootstrap once before the test script will work.
