Using Squid as the internal http proxy

I moved to a new building. In the old building I used to have a few Linux machines and virtual machines connected to internet directly. Now we are on a temporary network, all our machines and VMs are behind a firewall. To connect a machine to internet, I have to open the browser from that machine and load the login page, enter my username and password. This is fine with desktop PC’s.

Example content

Howdy! This is an example blog post that shows several types of HTML content supported in this theme.

Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum. Sed posuere consectetur est at lobortis. Cras mattis consectetur purus sit amet fermentum.

Curabitur blandit tempus porttitor. Nullam quis risus eget urna mollis ornare vel eu leo. Nullam id dolor id nibh ultricies vehicula ut id elit.

Etiam porta sem malesuada magna mollis euismod. Cras mattis consectetur purus sit amet fermentum. Aenean lacinia bibendum nulla sed consectetur.

Inline HTML elements

HTML defines a long list of available inline tags, a complete list of which can be found on the Mozilla Developer Network.

  • To bold text, use <strong>.
  • To italicize text, use <em>.
  • Abbreviations, like HTML should use <abbr>, with an optional title attribute for the full phrase.
  • Citations, like — Mark otto, should use <cite>.
  • Deleted text should use <del> and inserted text should use <ins>.
  • Superscript text uses <sup> and subscript text uses <sub>.

Most of these elements are styled by browsers with few modifications on our part.

Footnotes

Footnotes are supported as part of the Markdown syntax. Here’s one in action. Clicking this number1 will lead you to a footnote. The syntax looks like:

Clicking this number[^fn-sample_footnote]

Each footnote needs the ^fn- prefix and a unique ID to be referenced for the footnoted content. The syntax for that list looks something like this:

[^fn-sample_footnote]: Handy! Now click the return link to go back.

You can place the footnoted content wherever you like. Markdown parsers should properly place it at the bottom of the post.

Heading

Vivamus sagittis lacus vel augue rutrum faucibus dolor auctor. Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Morbi leo risus, porta ac consectetur ac, vestibulum at eros.

Code

Inline code is available with the <code> element. Snippets of multiple lines of code are supported through Pygments. Longer lines will automatically scroll horizontally when needed.

// Example can be run directly in your JavaScript console


// Create a function that takes two arguments and returns the sum of those arguments

var adder = new Function("a", "b", "return a + b");

// Call the function

adder(2, 6);
// > 8

You may also optionally show code snippets with line numbers. Add linenos to the Pygments tags.

What's Jekyll?

Jekyll is a static site generator, an open-source tool for creating simple yet powerful websites of all shapes and sizes. From the project’s readme:

Jekyll is a simple, blog aware, static site generator. It takes a template directory […] and spits out a complete, static website suitable for serving with Apache or your favorite web server. This is also the engine behind GitHub Pages, which you can use to host your project’s page or blog right here from GitHub.

It’s an immensely useful tool. Find out more by visiting the project on GitHub.
