It is my collection of Sage code that can be run directly in your browser.
To get even more Sage power (with lots more fancy stuff like privacy settings, collaboration, basically your own Sage server), sign up for a free Sage Math Cloud account! Or download and run a local copy of Sage.

These are the tutorials I used to construct this blog:
- Build A Blog With Jekyll And GitHub Pages
- Embedding Sage Cell Instances
- How I Created a Beautiful and Minimal Blog Using Jekyll, Github Pages, and poole
- Alphabetizing Jekyll Page Tags In Pure Liquid (Without Plugins)
Everything else below is from the original Jekyll Now project and is not written by me.
Jekyll is a static site generator that's perfect for GitHub hosted blogs (Jekyll Repository)
Jekyll Now makes it easier to create your Jekyll blog, by eliminating a lot of the up front setup.
- You don't need to touch the command line
- You don't need to install/configure ruby, rvm/rbenv, ruby gems
- You don't need to install runtime dependancies like markdown processors, Pygments, etc
- If you're on Windows, this will make setting up Jekyll a lot easier
- It's easy to try out, you can just delete your forked repository if you don't like it
In a few minutes you'll be set up with a minimal, responsive blog like the one below giving you more time to spend on writing epic blog posts!
Step 1) Fork Jekyll Now to your User Repository
Fork this repo, then rename the repository to yourgithubusername.github.io.
Your Jekyll blog will often be viewable immediately at http://yourgithubusername.github.io (if it's not, you can often force it to build by completing step 2)
Step 2) Customize and view your site
Enter your site name, description, avatar and many other options by editing the _config.yml file. You can easily turn on Google Analytics tracking, Disqus commenting and social icons here too.
Making a change to _config.yml (or any file in your repository) will force GitHub Pages to rebuild your site with jekyll. Your rebuilt site will be viewable a few seconds later at http://yourgithubusername.github.io - if not, give it ten minutes as GitHub suggests and it'll appear soon
There are 3 different ways that you can make changes to your blog's files:
- Edit files within your new username.github.io repository in the browser at GitHub.com (shown below).
- Use a third party GitHub content editor, like Prose by Development Seed. It's optimized for use with Jekyll making markdown editing, writing drafts, and uploading images really easy.
- Clone down your repository and make updates locally, then push them to your GitHub repository.
Step 3) Publish your first blog post
/_posts/2014-3-3-Hello-World.md to publish your first blog post. This Markdown Cheatsheet might come in handy.
You can add additional posts in the browser on GitHub.com too! Just hit the + icon in
/_posts/to create new content. Just make sure to include the front-matter block at the top of each new blog post and make sure the post's filename is in this format: year-month-day-title.md
- Install Jekyll and plug-ins in one fell swoop.
gem install github-pagesThis mirrors the plug-ins used by GitHub Pages on your local machine including Jekyll, Sass, Gemoji, etc.
- Clone down your fork
git clone firstname.lastname@example.org:yourusername/yourusername.github.io.git
- Serve the site and watch for markup/sass changes
- View your website at http://0.0.0.0:4000
- Commit any changes and push everything to the master branch of your GitHub user repository. GitHub Pages will then rebuild and serve your website.
