Here is an archive of what my desktop running Linux has looked like since 1995. There is about one screenshot a year. I blogged about this collection a while ago.

• January 22, 2011. In this screenshot, taken on the netbook I use as a wifi router, Ubuntu 10.04 is running in 64-bit mode. The theme is a high-contrast theme included with Ubuntu; I am running Deadwood in gdb to see if I can reproduce a crash that happened in Windows 7 approximately three months before.
• April 30, 2010. As blogged about here and here, I am seeing if I can be productive in an environment more recent than FVWM1. I'm giving XFCE 4.4 a try here; I previously used XFCE in 2001 and it looks a lot better than what was around back then.
• February 24, 2010 Here, I compare how my webpage looks in Opera 9 and Dillo 2.2, which is starting to support CSS. The toolbar at the top is created by VMware; since my hardware is not supported in CentOS 5, I am using CentOS 5.4 inside a virtual machine running on Windows XP Home Edition.
• February 6, 2009 In this screenshot, I am running three 32-bit virutal machines in 64-bit Ubuntu 8.10 using VMware player 2.5. Two of the virtual machines are running Windows XP; I use one for personal use, such as talking to my girlfriend on Skype or for playing games (as can be seen here). The other XP virtual machine is used for work; here I'm translating a document from English to Spanish, using Wordreference.com to look up a financial term. I also have a virtual machine running CentOS 5.2 with the old-school FVWM window manager that, while not as attractive as Gnome, is more suitable for my style of software development.

• KDE 1, May 1999
• FVWM 1, Feburary 1998. Designed to minimize eyestrain on DTSN laptop display.
• Caldera network desktop, June 28, 1996. This shows Word Perfect 6, the first commercial-grade word processor that was available for Linux. This also shows a proprietary desktop environment from a company that later went out of business.
• FVWM95, May 7 1996. This was the first desktop environment which emulated the look of Windows 95; it did not have Windows 95's user-friendliness.
• FVWM1, August 2, 1995. This is the very first screenshot I took of me using Linux.

Other tidbits

• Here is how the current design looks on a small-screen mobile device.
• Here is the initial 2011 redesign using hard-coded tables. Looks almost identical to the current (late 2011) design on most modern browsers, but the late 2011 update has improved rendering on older versions of Internet Explorer and, more importantly, better rendering on small-screen mobile devices.
• Here is my older webpage design from 2006. I used this design from 2006 until 2011.
• Here is the 2005 web page design, which was the first design to extensively use CSS. The 2006 design was a revision of this design.
