Kernel Hopping

Tim Brooks — Tue, 30 Jul 2013 00:27:00 +0100

I keep some old PC hardware around as a filesystem and test machine running Archlinux. I only occasionally bring it up (since the cloud does everything now, right?) but yesterday it failed to boot. Last time I had it on I updated Arch over the filesystem change but having done …

Odd. Checking my switch, I saw that there were no lights at all. For some …

So this is a test of code in markdown with Pelican.

For Python:

import readline, rlcompleter
readline.parse_and_bind("tab: complete")
print("Hello world!")

For C++:

#include <iostream>

int main() {
    std::cout << "Hello world!" << std::endl;
}

And for LaTeX

\begin{equation}
e^{i \pi} = -1
\end{equation}

The command line is very powerful: There are a few tools to learn that do very simple jobs, but piping their output to each other allows you to get things done without scripting. Here’s an example for downloading specific files in a grid dataset.
