Creating and Applying Diffs with Rsync
At work recently, we had a need to generate diffs between two different directory trees. This is so that we can handle deploys, but it’s after we’ve already generated assets, so we can’t just use git for the diff creation, since git diff doesn’t handle files that aren’t tracked by git itself. We looked into…

Monitoring a Web Page for Changes
Today, I found myself needing a way to monitor a page. I didn’t need anything fancy, just something that would alert me if a page changed in any way. So, I set up a simple bash script and cron job to monitor the page. For me, this was a perfect solution. Since I’ve got a…
