This article should acquaint you with basic Arduino programming
and show you how to write programs that interact with objects in the real world. (A
mandatory disclaimer: the last time I really studied
electronics was way back in high school, so this article focuses more on the
programming aspects, rather than the electronic side of things.)
In a previous article, we started a script that worked backward from a day and month
date and figured out the most recent year—including possibly the current
year—that would match that date occurring on that particular day.
iptables is the user-space tool for configuring firewall rules in the

iptables has been the Linux firewall solution since the 2.4 kernel.
In previous articles, I've looked at a number of uses for
JavaScript, on both the server and the client. I hope to continue my
exploration of such systems, particularly on the client side, in the
coming months.
Ditch your laptop and code in the cloud—it's easier than you'd think.
On September 19, 2011, I said goodbye to my trusty MacBook Pro and started
developing exclusively on an iPad + Linode 512. This is the surprising
story of three months spent working in the cloud.
Most people today are used to having a nice, intuitive graphical
environment when they sit down to use a computer. Gone are the days of
using a DOS machine or being lucky enough to have a dial-up account at
300 baud on a UNIX mainframe.
