A reoccurring issue with web development has always been cross-browser checking. Does the site work and layout correctly in Firefox, Internet Explorer, Chrome, Safari, Opera, blah blah. A huge problem with doing all my development on Linux is that I can’t easily check Internet Explorer on Windows. Most of the rest of my team also decline to use Windows and most of them use Apple (a whole other debate, but I will skip that for now). Our clients are totally Window’s shops so this presents a problem. We have tried running VM’s locally, but this has its own issues such as resource usage on your local machine. You start up a VM and watch all your RAM go bye bye.
The solution I have for this now, which seems to work alright, is to run another box with a decent amount of RAM and let everyone RDP into it for testing. This coupled with the virtual machines that Microsoft provides for testing has been working very well.
