Hi, I’m Florian or @qwtel and I’m the the developer of Hydejack, the Jekyll theme you’re currently looking at.

Hydejack is the complete package for professionals on the web. It features a blog suitable for both prose and technical documentation, a showcase for your projects, and a resume that is well-integrated with the design.

Your presence on the web — A blog, a portfolio and a resume.

Hydejack is highly customizable and lets you achieve a variety of styles. Below you can find a selection of variations.

Syntax Highlighting

Syntax highlighting powered by Rouge.

// 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

LaTeX Math Blocks

Write formulas in familiar LaTeX syntax. Powered by KaTeX.

  \phi(x,y) &= \phi \left(\sum_{i=1}^n x_ie_i, \sum_{j=1}^n y_je_j \right) \\[2em]
            &= \sum_{i=1}^n \sum_{j=1}^n x_i y_j \phi(e_i, e_j)            \\[2em]
            &= (x_1, \ldots, x_n)
                 \phi(e_1, e_1)  & \cdots & \phi(e_1, e_n) \\
                 \vdots          & \ddots & \vdots         \\
                 \phi(e_n, e_1)  & \cdots & \phi(e_n, e_n)
                 y_1    \\
                 \vdots \\


Hydejack can be customized in a variety of ways, using only the _config.yml file.
