Revisiting Linux Part 1: A Look at Ubuntu 8.04

It's Free – Libre
While the value of “free as in beer” is easy to describe, the value of “free as in speech – otherwise known as libre – is harder to relate. Nonetheless, rather large books have been written on the subject, so we'll try to stick with something condensed.
Virtually everything distributed with Ubuntu is an open source program in some manner. Many of the components of Ubuntu, such as the Linux kernel and the GNU toolset, are licensed under the GNU General Public License (GPL), which in a nutshell requires that any software distributed under the GPL license either include the source code with the software or a way to get the source code. Other bits of Ubuntu are under slightly different licenses with slightly different legal requirements, but the outcome is effectively the same. Ubuntu is free - you can get the source code to it and modify/distribute it as you see fit.
But when we're talking about Ubuntu, there's more than just being able to access the source, as most of the development teams that are responsible for the programs included in Ubuntu have their projects open for public participation. So not only can you take the code and modify it, but if your modifications are good enough they can be submitted back to the main project and possibly be included in a future version of the software. The fundamental idea of open source software is that users are empowered to see how software works and to modify it as they see fit. Other lesser benefits also exist, such as protecting authors' rights by preventing people from taking the code and improving it without sharing it (the GPL), and making sure all the authors are properly credited.
This does not always make open source relevant for the user however. The fundamental benefits of open source software are for people that are programmers, but most users are not programmers. Being able to see and edit the code is not necessarily useful if you don't know how to use it. Even with a background in programming, I would be hard pressed to be able to quickly contribute significant code changes to most projects; very few programs are small and simple enough to be able to easily jump into these days.
Still, there are some definite benefits for those of us that can't throw out code like Linux's chief architect Linus Torvalds. The most direct benefit of course is that this software exists at all. Since all of the software in Ubuntu is free as in beer, paid developers do not develop many of the programs. Open source as a default state makes it easier for people to contribute to the development of software, and that means it's easier for such gratis software to be continually developed in the first place.
Open source software is also a benefit for the longevity of software. Since no one person has absolute control over a project, no one can terminate it. This means that someone else can pick up a project and continue should the original developer(s) quit, as is sometimes the case with old software. It also allows for software to be forked, which is to take the code from a project and create a derivative separate from the original project – the benefit being that a forked project can be taken in a different direction than the original developer may want. As proof of the importance of forking, there are a number of programs in Ubuntu that are forks of older projects, such as X11 (otherwise known as just X), Ubuntu's base windowing system.
Finally, open source software is beneficial to overall software security. If you can see the source, you can analyze it for possible bugs. If you can edit the source, you can fix those bugs rather than wait for someone else to do so - and we can't even begin to overstate the importance of this. The direct relevance to the average user is once again limited here since most people cannot read or write code, but it does filter down through benefits such as rapid patching of security vulnerabilities in some cases. The security benefits of Ubuntu being open source are some of the most important reasons we consider Ubuntu to be secure.
In short: even if you can't code you benefit from Ubuntu being a free (libre) operating system.

"Not that it would necessarily be of much use, the last time I saw any statistics for instant messaging network usage, the vast majority of North American users were on AOL’s AIM network."IM use is highly regionalized. As such, AIM is clearly the dominant IM in the USA. However, Canada is dominated by MSN Messenger, and has been for many years (most of us migrated from ICQ to MSN around the release of Windows XP, I believe, due to the bundling of then Windows Messenger).
So, if Canada is dominated by MSN, while I can't speak for Mexico, it's misleading to claim that "the vast majority of North American users". As a Canadian, I can't think of anybody I know in person that uses AIM. They all use MSN or Google Talk without exception.

For myself, the thing that most bugs me when I have to go back to Windows is all the missing features from the window manager. I've come to rely on having multiple workspaces on my desktop, but I can adjust to having just one fairly easily when I'm not working on a lot of different stuff at once. What really bugs me, though, is how much more effort it takes to move or resize windows in Windows. On Linux I can press ALT and then click anywhere on the window, but with Windows I have to carefully click the title bar or the very edge of the window and that takes a noticeably longer time once you're used to doing things differently.Oh, and I find that the Linux scheduler seems to be noticeably better than the Windows one in preserving responsiveness when the system is under load.

Great article!How about some benchmarks of "minimal" distros (like Puppy, Tine Core, ...)??
I like the idea of "ressurect" an old PC, but I would like to see benchmarks in Quad Cores, i7 too!
Anandtech is great, Bench(beta) is awesome!!
(sorry by bad english)
Thanks

A few months ago most major trackers unbanned Transmission, but it still doesn't seem to be universally accepted on private trackers.I remember offhand (I could be wrong) that the main gripe was due to the fact it made excessive queries and thus flooded trackers with requests, or had the ability to.

I think you really need to mention the big picture here.I myself just tried Ubuntu for the first time 2 months ago and although I will admit that I have spent up to 8 hours trying to figure out how to install a specific program (before I found out there was a way to get the package manager to find the install), and I wanted to smash my computer at times. Now that I have learned quite a bit more, I realized that the few things I have installed worked great and flawlessly.
Anyhow back to the big picture. I can understand some of your concerns with how the OS will work with specific programs but what I have found is that most people I know use their computers for 2 things email and web browsing. Most of these people are constantly having problems with the system running too slow and cant seem to get rid of hidden viruses/malware. So I think that those people could easily be much happier with a simple OS like Ubuntu just for email and web browsing (And I would get a heck of alot of less calls from my dad asking my why his computer is running too slow). Lets also not forget that everything is moving to be browser compatible (like you mentioned).
Also, for people like myself, I use my Ubuntu system for a file server as well as a media center (XBMC is Awesome).
So, yes, for burning DVDs/CDs/Playing Games/Microsoft Office, I see no reason why you wouldn't use windows, but I think 95% of the users would be perfectly fine with ubuntu which is something that Mr Bill would not be very happy about when the public realizes this.

I think you have missed one small but important part.I am Ubuntu user since 8.04. I came to Linux because of the constant treat of viruses.
Last month I have installed 7 and it is very user friendly and I think it is very user frinedly but after Avira Antivir got crashed by virus I installed Kaspersky INternet security 2010. then it took almost twice as long to boot. Then I gladly returned to Ubuntu 9.04. Because MIcrosoft can not exist without Antivirus I think you should do some real benchmarking and test windows WITH Antivirus.
On Ubuntu I have ClamWin just in case i get some files from Windows users:)
Thanks

just wanted to point out that you can install software under the LiveCD. Of course it does not install on the hard drive. It remains on a ram-drive, so when you reboot, it's gone. It's still useful, if you wish to test out some package or perform some task with a tool not installed by default on the LiveCDstrikeback03 - Wednesday, August 26, 2009 - link
Even more useful (and not mentioned) is that Ubuntu can easily run off a flash drive, and more recent versions even include a GUI tool for installing it to one. Then all installs and other changes are saved from session to session, and everything runs much more quickly than the LiveCD.Mr Pearce - Wednesday, August 26, 2009 - link
It would be great if you could do more articles on compiler and especially driver performance differences. That was the most interesting part of this article.Ryan Smith - Wednesday, August 26, 2009 - link
This is what Part 2 will look at. I can compile some stuff by hand to see if it closes the Windows/Ubuntu gap, and I have plenty of video cards on hand to test what I can when it comes to graphics.
