At one of my first jobs, we were tasked with building a new website for the company. Since we were the first in-house web development team (everything done prior to us had been contracted out), we had NO relevant software or tools available to use because the company had never needed them before.

On top of that, our computers were on complete lockdown: we had no permissions to install anything ourselves, and any software installation requests had to go through a formal review process that took a minimum of a few months for approval.

So: for the first couple of months, we coded everything in Notepad (!) on Windows (so no autocomplete, no syntax highlighting, etc.)...and tested only in IE6, the sole browser we had at our disposal 😮
