This is the first post of this blog. I do not currently plan to write here, but I wanted to test the Jekyll setup.

function print_hi(name)
  println("Hi, $name")
end
print_hi("JeanPetrelle")

#=> prints 'Hi, JeanPetrelle' to STDOUT.

$ \TeX $ is also supported.

so if I write say, \[ A \xrightarrow{f} B, \] it is rendered properly.

How to use $\TeX$ packages like tikz though?
