This will be the first part in a new series of articles about setting up your own Ubuntu LAMP (Linux, Apache, MySQL, PHP) server. If you are already proficient with Linux and/or Ubuntu then you can skip this first part because it is just about the basic post-install set up and configuration. For those of us who haven’t set up an Ubuntu system a hundred times over, here is the quick and dirty base Ubuntu set up guide.

Once you have your Ubuntu operating system installed there are still a few things you need to do to get it ready for prime time. A fresh install of Ubuntu will have a root account (you chose the password during installation) and the SSH server running. At the moment my recommendation for version is 10.04 LTS.

Without further ado, lets get this show on the road. Start by connecting to your system via SSH and logging in to the root account. (For Windows users I recommend PuTTY as an SSH client)

Ultimate web site optimization trick: data URIs

Are you an obsessive compulsive web site optimization nut? Are you willing to sacrifice maintainability for one less HTTP request? Have people ever asked you to seek a mental health professional because of your OCD? If so, then you are in good company. Us optimization nuts may not be very well received when we start building a project, but we become very appreciated when someone asks how to make it scale. Depending on who you ask, web optimization is either the most useless talent ever or the single most important skill on a web developers resume.

Allow me to broaden your optimization toolbox with the ultimate HTTP connection killer, the data URI scheme. Most web developers have never heard of data URIs but they can dramatically reduce the number of HTTP connections required to download your web site.

This article will explain what data URIs are, how to use them, and how to properly implement them.

How to circumvent internet filtering and enhance privacy

Censored

The whole world knows about the so called “Great Wall” that protects the Chinese people from dangerous western ideals, the serious concerns about internet privacy in the United Kingdom, now we have Australia making a real push towards internet filtering legislation as well as all of North America and most of Europe signing on with the ACTA legislation. Of course we still have Iran blocking news, social media and even gmail. But even countries that we wouldn’t expect to support censorship are signing bad legislation, such as France, New Zealand, and Ireland.

For at least a decade the very idea of filtering information was something first world countries laughed at as a tactic only dictatorships and xenophobes would seriously consider, now it seems the stage is changing and governments and ISPs are becoming more open to the idea of national censorship.

This is a terrible, and dangerous trend. I for one hope the aussies block the forced internet filtering law and I hope the whole world sees ACTA as the scam that it is. There is a quote that I often like to cite when the topic of internet filtering comes up, “The internet sees censorship as damage, and automatically routes around it”. Unfortunately, when censorship happens at the ISP level, that automatic routing is broken, so you have to do some manual routing to circumvent the broken tubes.

I think it is important to know how to get around censorship schemes and I believe that the greater the number of people with this knowledge the better off the internet, and the world will be. So here’s how to circumvent internet censorship, the VPN.

Calculate page size and view port position in JavaScript

Have you ever had to try to figure out the dimensions of a page or browser in JavaScript? This task seems very simple at first glace, every browser has simple properties that will give you this information. Unfortunately, not every browser agrees what object these properties belong to, or even what the names are.

I’ve built a couple nifty tools in JavaScript that need to know the exact dimensions of the document as well as the exact dimensions of the browser view port. Since these scripts are uses on very high traffic sites with a very wide audience I have had to make sure they work in a multitude of browsers.

In this article I will show you how I support all modern (and not so modern) browsers with one function and I will explain a little about exactly what techniques I’m using to accomplish this.

Building a home Network Attached Storage server. Part 3: Wrapping up and product reviews

April 6th, 2010 – System Administration (, , ) 6 Comments »

It’s taken me a quarter of a year to write this series, partially because I wanted to make sure I got it right, partially because I’m a lazy writer. But now the wait is over, here is the third and final installment of the NAS series about my home NAS server build.

80MB/s Network Throughput!

80MB/sec across the network!

In this article I will discuss the final garnishing that you need to do to get you NAS to fire and forget server status. I will also give you my reviews of the various pieces of hardware that I used and offer a general wrap up statement on the project.
