CVS for Beginners


OK. You and ten of your closest pals have decided to work on the greatest-ever web page/Perl script/whatever. You all want to work on the same file from the same location at the same time. Then when you’re good and ready, you’ll roll out releases of the code.

Does it sound like a logistical impossibility? Well it’s not if you have the right tool — a source control system.

A good source control system is the secret behind any successful web development project. If you look at any large-scale software development project, you’ll see a source control system at work.

Set Up Dynamic DNS

Now that everybody* has a home broadband connection, the need for IP addresses is a growing concern. With the rollout of IPv6 still pending, IP addresses are a limited resource.

Set Up a Home Server

Setting up a home server running an open-source operating system is a popular and useful activity. Useful in what ways, you may ask.

As you can guess, we have a great many tutorials on Webmonkey for getting the most out of that machine in your closet. But here are some guidelines for the hardware side of it.

Set Up a Debian or Ubuntu Machine as a Maildrop

The setup described here enables you to store all your email (and email for other people) on a single machine, which might be a home server, a remotely hosted server, or even a desktop, and then access it from anywhere.

Modify User Permissions

File permissions on Unix and Linux are one of the most ubiquitous stumbling blocks for even regular users of those operating systems. The intricate structure of which users on a system are allowed to do what is one of the foundations of Unix, providing security and interoperability, but at times it can make working with the system a pain. Here’s a look at how permissions work and how to work with them.
