Dieter Rams, Vitsœ's furniture designer. Ten principles for good design (sometimes referred to as the ‘Ten commandments’).

Task Write a program that prints the integers from 1 to 100 (inclusive). But: for multiples of three, print Fizz (instead of the number)...

Mojo one-liners are just Perl one-liners. You will use -E (or -e) to write the program. You might use -n to loop over input, or -p to do the same while printing $_ after each item, just like normal one-liners.

To get the extra Mojo goodness, add -Mojo. The name itself is a cute hack. Since -M is what loads a module on the command line, the module name is therefore ojo.

From its start, Perl comes with most (Unix) core operating system trickery like forks, events and signals. So, you can implement real performing daemons for interesting tasks.

We will get into various features which show how straight-forward it is to implement an Apache-like webserver, with VirtualHosts, proxies, etc.

But we start by discussing many options how to set-up servers: processes, event-loops, and so on... before we reach to HTTP-servers processing requests.
