BPMeasure
Languages: This was one of the first projects I worked on when I was new to programming. At the time, I ended up using Java since I felt comfortable with it. However, the code was unnecessarily complex. For my site, I decided to learn enough JavaScript (for BPM calculations) and jQuery (for form validation) to port my original project onto my site. The result is a simpler, more stable, and faster program. These web languages and frameworks also allow it to be displayed more easily on desktops, laptops, tablets, smart phones, and more.
Overview: BPMeasure is an easy way for DJ's to find out the beats-per-minute (BPM) percentage amount to increase or decrease to, given two songs. Previously, someone playing two songs would have to either do the math in their head (which leads to errors), or just know from previous experience what tempo they would need to increase to based on the current songs BPM.
